to the Installation Method and Precautions of Drawer Slide Rails
Drawers are an essential component of furniture, and the quality of drawer slides greatly affects the overall user experience of drawer furniture. Good quality drawer slides ensure smooth operation and excellent usability, while poor quality ones can result in a frustrating experience. In this article, we will discuss the installation method of drawer slides and the precautions that need to be taken during the installation process.
How to Install Drawer Slides:
1. If you are installing drawers in furniture that is not a finished product and is being made on-site by a carpenter, you need to reserve space for the drawer to bounce back before installing the slide rail. However, if you are buying finished furniture, you can skip this step as the manufacturer has already designed and produced the furniture with the necessary space.
2. The installation methods of drawers can be categorized into low drawers and inner drawers. Low drawers have a protruding drawer panel even when fully pushed into the cabinet, while inner drawers have the drawer panel completely inside the box. Ensure you understand the type of drawer you are working with before proceeding with the installation.
3. The drawer slide rail consists of three parts: the movable rail (inner rail), the middle rail, and the fixed rail (outer rail).
4. Before installing the slide rail, the inner rail (movable rail) needs to be removed from the main body of the slide rail. Carefully detach the inner rail without causing any damage to the slide rail. The disassembly process is quite simple – locate the snap spring on the inner rail and gently remove it. Remember not to disassemble the outer rail or the middle rail.
5. Start by installing the outer and middle rails of the split slide on both sides of the drawer box. Then, install the inner rails on the side panels of the drawer. If you are working with finished furniture, you will find pre-drilled holes on the drawer box and drawer side panels for easy installation. However, for on-site installations, you will need to punch the holes yourself. It is recommended to assemble the entire drawer before installing the slide rail. The tracks have holes that allow you to adjust the up-down and front-back distance of the drawer.
6. Finally, place the drawer into the box. While installing, make sure to press the snap ring of the inner rail mentioned earlier, and then gently push the drawer into the box parallel to the bottom.
Precautions for Installation of Drawer Slide Rails:
1. Pay attention to the selection of the right size. Different types of drawers require different types of slide rails. When installing, ensure that the length of the slide rail matches the length of the drawer. If the slide rail is too short, the drawer will not fully extend, and if it is too long, it will be difficult to install.
2. Approach the installation process by thinking in reverse from the dismantling process. Installing drawer slides is relatively simple if you think in reverse and follow the steps of removal.
Installing drawer slide rails requires technical expertise and patience. It is always advisable to seek the assistance of professionals to ensure proper installation. By doing so, you can maximize the performance and usability of your drawer slides. Attempting to force the installation without proper knowledge can lead to significant problems. Therefore, it is essential to focus on the details and follow the correct procedure to achieve a successful installation.
How to Install the Track on the Drawer and How to Position It:
The installation process is as follows:
1. Installing drawer slide rails is simple, but certain details require attention to ensure that the drawers function properly. We usually refer to three-section slides, where the drawer slides consist of three parts: the outer rail, middle rail, and inner rail.
2. When installing the slide rail, you need to detach the inner rail from the main body of the slide rail. The removal process is also straightforward. The back of the drawer slide rail will have a spring buckle that needs to be released to remove the rail.
3. Note that the middle rail and outer rail are not removable and should not be forced to remove.
4. Begin by installing the outer and middle rail parts of the split slide on both sides of the drawer box. Then, install the inner rail on the side panel of the drawer. Finished furniture usually has pre-drilled holes for easy installation, while on-site installations require hole punching.
5. It is recommended to assemble the drawer before installing the slide rail. The rail has two holes for adjusting the up-down and front-back distances of the drawer. Ensure that the left and right slide rails are at the same horizontal position.
6. Proceed to install the inner and outer rails. Use screws to fix the inner rails to the measured position on the drawer cabinet, making sure they are aligned with the installed and fixed middle and outer rails.
7. Tighten the two screws in the corresponding holes.
8. Repeat the same process on the other side, keeping the inner rails on both sides horizontal and parallel.
9. If the middle and outer rails are not horizontal, the drawer may not slide properly. In this case, check the position of the outer rail and adjust the inner rail accordingly.
10. After installation, test the drawer by pulling it in and out. If any issues arise, make the necessary adjustments. If the drawer slides smoothly, the installation is complete.

The rapid development of the space industry has necessitated the utilization of large-scale space deployment mechanisms to meet various application requirements. However, due to the limitation of space vehicle capacity, these mechanisms need to be folded and stored during the launch phase. When unfolded, these mechanisms may experience reduced rigidity, resulting in lower natural frequencies and undesirable coupling vibrations between the spacecraft body and the deployment mechanism. Therefore, it is essential to understand the factors influencing the natural frequency of the space hinge rod deployment mechanism for better design and calibration.
Abstract:
When different materials and reinforcement methods are employed in the space hinge rod expansion mechanism, their natural frequencies differ significantly. Modal analysis using finite element software ANSYS can be conducted to determine the impact of material density and reinforcement method on the natural frequency. The research findings indicate that material density has a significant influence on the natural frequency, with a greater impact observed for higher densities. Additionally, different reinforcement methods also lead to substantial natural frequency differences. This study provides valuable guidance for the dynamic analysis and further optimization of space hinge rod deployment mechanisms.
Model of Space Hinge Rod Deployment Mechanism:
The space hinge rod deployment mechanism consists of a frame part and a rod part, with a scissor support formed by the middle two rods of the frame and the rods. The frame is equipped with hinge shafts at both ends, allowing it to be hinged with the upper and lower frames. The rods' hinge shafts serve as three-point fixation, ensuring stability. Moreover, two strengthening structures are included: the connecting rod structure and the steel wire rope structure. The connecting rod reinforcement employs U-shaped rods connected in the same direction, while the steel wire rope reinforcement involves winding a steel wire rope around a roller for added rigidity.
Finite Element Model:
The frame and strut parts are modeled using solid three-dimensional modeling with the Solid45 unit. This unit accurately reflects the actual situation and provides precise results. On the other hand, the reinforcement part is modeled directly using the BEAM188 unit, offering powerful linear analysis capabilities and better section data definition functions. The beam element generates a one-dimensional mathematical model of the three-dimensional structure, enabling efficient and effective analysis.
Modal Analysis of Space Hinge Rod Deployment Mechanism:
Modal analysis aids in determining the vibration characteristics of the structure, including its natural frequency and mode shape. These parameters are crucial in bearing dynamic loads and serve as the basis for other dynamic analysis problems. Since the space expansion mechanism requires lightweight design, modal analysis of aluminum and carbon fiber materials with either connecting rod or steel wire rope reinforcement is conducted. The obtained fundamental frequencies are presented in Table 1.
The study reveals that the natural frequencies of space hinge rod deployment mechanisms vary based on the materials and reinforcement methods employed. Material density has a significant influence on the natural frequency, with higher densities leading to lower fundamental frequencies. Furthermore, different reinforcement methods result in substantial differences in the natural frequency. Overall, understanding these factors enables the selection of appropriate reinforcement methods and materials for improved performance of space hinge rod deployment mechanisms.
In conclusion, the research findings highlight the importance of considering material density and reinforcement method in the design and calibration of space hinge rod deployment mechanisms. The information provided in this study will aid in the accurate selection of materials and reinforcement methods, thus optimizing the dynamic performance and stability of space deployment mechanisms.

An Analysis of the Casting Process
The bracket part, made of ZL103 alloy, has a complex shape with numerous holes and thin thickness. This poses challenges during the ejection process, as it is difficult to push out without causing deformation or dimensional tolerance issues. The part requires high dimensional accuracy and surface quality, making the feeding method, feeding position, and part positioning crucial considerations in mold design.
The die-casting mold, depicted in Figure 2, adopts a three-plate type, two-part parting structure, with a center feed from the point gate. This design yields excellent results and an appealing appearance.
Initially, a direct gate was used in the die-casting mold. However, this resulted in difficulties during the removal of residual materials, affecting the quality of the casting's upper surface. Moreover, shrinkage cavities were observed at the gate, which did not meet the casting requirements. After careful consideration, a point gate was chosen as it proved to produce smooth casting surfaces with uniform and dense internal structures. The inner gate diameter was set at 2mm, and a transition fit of H7/m6 was adopted between the gate bushing and the fixed mold seat plate. The gate bushing's inner surface was made as smooth as possible to ensure proper separation of the condensate from the main channel, with a surface roughness of Ra=0.8μm.
The mold employs two parting surfaces due to the gating system's shape limitations. Parting Surface I is used to separate the remaining material from the sprue sleeve, while Parting Surface II is responsible for removing residual material from the casting surface. The baffle plate at the end of the tie rod facilitates sequential separation of the two parting surfaces, while the tie rod maintains the desired distance. The length of the mouth sleeve (remaining material separated from the sprue sleeve) is adjusted to aid in the removal process.
During parting, the guide post emerges from the movable template's guide hole, allowing the mold cavity insert to be positioned by the nylon plunger installed on the movable template.
The original design of the mold included a one-time push rod for ejection. However, it resulted in deformations and size deviations in the thin, long castings due to the increased tightening force on the moving mold's center insert. To address this issue, secondary pushing was introduced. The mold incorporates a hinge connection structure, allowing simultaneous movement of the upper and lower push plates during the first push. When the movement exceeds the limit stroke, the hinge bends, and the push rod's force only acts on the lower push plate, stopping the motion of the upper push plate for the second push.
The mold's working process involves the rapid injection of liquid alloy under pressure, followed by the mold opening after formation. The initial separation occurs at the I-I parting surface, where the remaining material at the gate is detached from the sprue sleeve. The mold continues to open, and the remaining material from the ingate is pulled off. The ejection mechanism then initiates the first push, wherein the lower and upper push plates move forward synchronously. The casting is smoothly pushed away from the moving plate and the fixed mold's center insert, allowing for core-pulling of the fixed insert. As the pin shaft moves away from the limit block, it bends towards the mold's center, causing the upper push plate to lose force. Subsequently, only the lower push plate continues to move forward, pushing the product out of the cavity of the push plate through the push tube and push rod, completing the demolding process. The ejection mechanism resets during mold closure through the action of the reset lever.
During mold usage, the casting surface initially exhibited a mesh burr, which gradually expanded with each die-casting cycle. Research identified two factors contributing to this issue: large mold temperature differences and a rough cavity surface. To address these concerns, the mold was preheated to 180°C before use and maintained a surface roughness (Ra) of 0.4μm. These measures significantly improved casting quality.
Thanks to the nitriding treatment and proper preheating and cooling practices, the mold's cavity surface enjoys enhanced wear resistance. Stress tempering is carried out every 10,000 die-casting cycles, while regular polishing and nitriding further increase the mold's lifespan. To date, the mold has successfully completed over 50,000 die-casting cycles, demonstrating its robust performance and reliability.
