Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a molding die for a textile machine casing. Background Technology

[0002] In the field of textile machinery manufacturing, the outer casing of a textile machine is the core protective and aesthetic component of the entire machine. Its structural integrity directly affects operational safety, protecting internal components and preventing accidental contact by personnel; dimensional accuracy affects assembly compatibility and determines the seamless integration with the entire machine; and molding efficiency is related to production cost-effectiveness, with high-efficiency molding reducing costs. These three factors collectively constitute the key to evaluating the performance and economy of a textile machine. Traditional textile machine housing molding dies typically employ a "single punch + single die" structure. During operation, a single drive source propels the punch into the die cavity in a single direction, first forming the main body of the housing. Subsequent processes such as drilling and milling are then used to process features like heat dissipation holes and assembly clips to complete the overall housing molding. However, the existing textile machine housing molding dies, due to their unidirectional extrusion structure of "single punch + single die," are prone to uneven stress on the housing cavity, leading to surface warping and affecting molding accuracy. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a molding die for a textile machine casing.

[0004] The molding die for the outer shell of a textile machine provided by this utility model includes a base on which a calibration rod is mounted; an upper mold base mounted on the calibration rod, a lower module mounted on the base, an upper module mounted on the upper mold base, and telescopic rods mounted on both the lower and upper modules. Each telescopic rod is fitted with a return spring. The cooperation between the telescopic rod and the return spring can effectively balance the mold closing pressure and avoid local pressure concentration; and a side pressure component mounted on the telescopic rod can assist in conforming to the contour of the outer shell. Preferably, the side-pressure component includes a protective box and a compression plate, with the protective box mounted on the telescopic rod located on the lower module and the compression plate mounted on the telescopic rod located on the upper module.

[0005] Preferably, a cylinder is installed inside the protective box, a die cavity body is installed on the cylinder, and a silicone pad is installed on the die cavity body. The silicone pad is made of high temperature resistant material, which is conducive to adjusting the position of the die cavity body through the cylinder to adapt to different specifications of shells. It also helps the silicone pad to protect the surface of the shell and avoid scratches during high temperature molding.

[0006] Preferably, a sliding groove is provided at the bottom of the protective box, and a sliding block is installed at the bottom of the die cavity body. The sliding block is slidably connected to the sliding groove, which is conducive to the smooth movement of the die cavity body driven by the cylinder, and makes it easier to ensure the accuracy of die position adjustment and avoid deviation affecting molding accuracy.

[0007] Preferably, both the upper and lower modules are equipped with mold bodies, and the protective box and the extrusion plate are respectively provided with through holes of the same size. The mold body is located in the through holes, which is conducive to the stable penetration of the mold body through the side pressure component. When the side pressure component applies pressure to conform to the outer shell contour, it does not interfere with the core forming function of the mold body.

[0008] Preferably, a hydraulic cylinder is mounted on the upper mold base via a motor frame, and the output end of the hydraulic cylinder is connected to the upper module. This facilitates the provision of a stable and controllable mold-closing driving force to the upper module, enabling precise control of the mold-closing pressure and speed, and ensuring consistent molding.

[0009] Preferably, a water storage tank is installed on the base, and a water pump is installed inside the water storage tank. The water pump has an outlet pipe and a suction pipe installed at its outlet and inlet ends, respectively. The end of the outlet pipe away from the water pump is connected to the main body of the die cavity, which is conducive to building a cooling circulation system to cool down the main body of the die cavity, facilitates the rapid removal of molding heat, and reduces the deformation of the outer shell caused by uneven cooling.

[0010] Preferably, the water storage tank has a water inlet with a cap, which facilitates timely replenishment of cooling water through the water inlet and makes it easy for the cap to seal the water storage tank, preventing dust and impurities from entering and contaminating the cooling water.

[0011] Compared with related technologies, the molding die for the textile machine housing provided by this utility model has the following advantages: 1. This utility model, through its designed side-pressure component, ensures that during the molding of a textile machine shell, when the upper module is moved downwards by the hydraulic cylinder and the mold body is embedded in the molding area, the protective box and extrusion plate of the side-pressure component are subjected to the elastic pre-tightening force and linkage force of the telescopic rod and the return spring, causing them to respectively conform to the bottom and top contours of the shell, simultaneously applying balanced lateral auxiliary pressure. Unlike traditional molds that only apply unidirectional main pressure, this design ensures that during shell molding, both the side wall curvature and edge details are precisely wrapped and supported by lateral pressure, achieving multi-directional pressure balance and eliminating localized stress concentration. This significantly improves the flatness and contour accuracy of the shell, preventing warping and deformation.

[0012] 2. This utility model, through its designed water storage tank, water pump, water outlet pipe, and water suction pipe, enables the cooling and shaping of the textile machine shell after molding. When the main body of the die cavity needs rapid cooling due to accumulated heat during molding, the cooling water is first drawn from the water storage tank through the suction pipe by the forward-rotating water pump, and then injected into the internal flow channel of the die cavity through the water outlet pipe. After the water is absorbed, the water pump switches to reverse, and the cooled water, having absorbed heat, flows back to the water storage tank along the same water outlet pipe, forming a "single-pipe bidirectional" cooling cycle. Unlike traditional natural cooling or dual-pipe water return methods, this ensures that during the cooling and shaping of the shell, whether it's deep cooling inside a thick-walled shell or uniform cooling of a thin-walled shell, the circulating cooling water efficiently heats the shell, truly achieving rapid and uniform cooling without uneven cooling and internal stress. This improves the shell shaping efficiency and structural stability, avoids cooling deformation, simplifies the system structure, reduces pipe space, and lowers mold complexity.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0017] Please see Figure 1 - Figure 5A molding die for a textile machine housing includes a base 1, on which a calibration rod 2 is mounted; an upper mold base 3 mounted on the calibration rod 2, a lower module 4 mounted on the base 1, an upper module 5 mounted on the upper mold base 3, and telescopic rods 6 mounted on both the lower module 4 and the upper module 5. Each telescopic rod 6 is fitted with a return spring 7. The cooperation between the telescopic rod 6 and the return spring 7 can effectively balance the mold closing pressure and avoid local pressure concentration; and a side pressure component 8 mounted on the telescopic rod 6 can assist in conforming to the contour of the housing.

[0018] The following describes some embodiments of this application in detail with reference to the accompanying drawings: The side-pressure component 8 includes a protective box 9 and an extrusion plate 10. The protective box 9 is installed on the telescopic rod 6 located in the lower module 4, and the extrusion plate 10 is installed on the telescopic rod 6 located in the upper module 5. Please see Figure 1 - Figure 3 Through the designed side-pressure component 8, during the molding of the textile machine shell, when the hydraulic cylinder 18 drives the upper module 5 to move downward and the mold body 16 is embedded in the molding area, the protective box 9 and the extrusion plate 10 of the side-pressure component 8 are driven by the elastic pre-tightening force and linkage force of the telescopic rod 6 and the return spring 7, respectively, to fit against the bottom and top contours of the shell, and simultaneously apply lateral balanced auxiliary pressure. Unlike the structure of traditional molds with only unidirectional main pressure, this ensures that during the molding of the shell, regardless of the curvature of the side wall or the edge details, it can be accurately wrapped and supported by lateral pressure, achieving multi-directional pressure balance and no localized force concentration, greatly improving the flatness and contour accuracy of the shell, and avoiding warping and deformation.

[0019] In addition, a cylinder 11 is installed inside the protective box 9. A cavity body 12 is installed on the cylinder 11. A silicone pad 13 is installed on the cavity body 12. The silicone pad 13 is made of high temperature resistant material, which is conducive to adjusting the position of the cavity body 12 through the cylinder 11 to adapt to different specifications of shells. It is also convenient for the silicone pad 13 to protect the surface of the shell and avoid scratches during high temperature molding.

[0020] Meanwhile, a sliding groove 14 is provided at the bottom of the protective box 9, and a sliding block 15 is installed at the bottom of the die cavity body 12. The sliding block 15 is slidably connected to the sliding groove 14, which is conducive to the smooth movement of the die cavity body 12 driven by the cylinder 11, which helps to ensure the accuracy of die position adjustment and avoids deviation from affecting molding accuracy. In this technical solution, such as Figure 1 - Figure 5As shown, mold bodies 16 are installed on both the upper module 5 and the lower module 4. The protective box 9 and the extrusion plate 10 are respectively provided with through holes 17 of the same size. The mold body 16 is located in the through hole 17, which is conducive to the stable penetration of the mold body 16 through the side pressure component 8. When the side pressure component 8 applies pressure to conform to the outer shell contour, it does not interfere with the core forming function of the mold body 16. A hydraulic cylinder 18 is installed on the upper mold base 3 through the motor frame. The output end of the hydraulic cylinder 18 is connected to the upper module 5, which is conducive to providing a stable and controllable mold closing driving force for the upper module 5. It is convenient to accurately adjust the mold closing pressure and speed to ensure the consistency of forming.

[0021] The base 1 is equipped with a water storage tank 19, and a water pump 20 is installed inside the water storage tank 19. The water pump 20 has an outlet pipe 21 and a suction pipe 22 installed at its outlet and inlet ends, respectively. The end of the outlet pipe 21 away from the water pump 20 is connected to the cavity body 12, which is conducive to building a cooling circulation system to cool down the cavity body 12, and facilitates the rapid removal of molding heat, reducing the deformation of the shell caused by uneven cooling.

[0022] In addition, the water storage tank 19 is provided with a water inlet 23 and a cap 24 is installed on the water inlet 23, which is conducive to timely replenishment of cooling water through the water inlet 23 and facilitates the cap 24 to seal the water storage tank 19 to prevent dust and impurities from entering and contaminating the cooling water.

[0023] The working principle of the side pressure component 8 is explained below: First, pre-start preparations and debugging are carried out to ensure that all systems are in a stable, ready-to-operate state. Personnel must first conduct a comprehensive inspection of the overall mold structure, focusing on confirming that all components on base 1 are securely installed, that calibration rod 2 is not misaligned or loose, and that the upper mold base 3 can slide smoothly along calibration rod 2, providing precise guidance for subsequent mold closing actions. Next, the cooling system is prepared. The cap 24 of the water storage tank 19 is opened, and sufficient cooling water is injected into the tank through the inlet 23. After filling, the cap 24 is tightened to prevent dust and impurities from entering and contaminating the water. Simultaneously, the sealing of the water pump 20 and connecting pipes is checked to ensure there are no potential leaks, laying the foundation for subsequent cooling circulation. Subsequently, according to the specifications of the shell to be molded, the position of the die cavity body 12 is adjusted: the cylinder 11 inside the protective box 9 is activated, and the cylinder 11 drives the die cavity body 12 to move. With the cooperation of the bottom sliding block 15 and the sliding groove 14 inside the protective box 9, the die cavity body 12 is smoothly adjusted to the appropriate size. At the same time, the silicone pad 13 on the surface of the die cavity body 12 is checked to ensure that it is undamaged and fits tightly, so as to effectively protect the surface of the shell during high-temperature molding. Finally, the mold closing parameters are set. The output pressure and moving speed of the hydraulic cylinder 18 are adjusted by the control terminal. Reasonable parameters are determined according to the shell material and thickness to ensure that the mold closing process is stable and controllable.

[0024] Secondly, the mold-closing procedure is initiated and lateral auxiliary pressure is applied simultaneously to achieve initial shell forming. After the preparation work is completed, the hydraulic cylinder 18 starts working, driving the upper mold base 3 to move the upper module 5 smoothly down along the calibration rod 2. As the upper module 5 gradually approaches the lower module 4, the mold body 16 on both gradually embeds into the forming area. At this time, the side pressure component 8 installed on the telescopic rod 6 begins to move in tandem. Since the telescopic rod 6 is fitted with a return spring 7, under the action of the mold-closing pressure, the return spring 7 generates an elastic preload, causing the protective box 9 and the extrusion plate 10 to fit against the bottom and top contours of the shell respectively, and simultaneously applying lateral balanced auxiliary pressure. This multi-directional pressure coordination method, unlike the traditional mold structure that only relies on unidirectional main pressure, ensures that during shell forming, both the side wall curvature and edge details can be accurately wrapped and supported by lateral pressure, effectively avoiding local stress concentration, providing a guarantee for improving the flatness and contour accuracy of the shell, and reducing the risk of warping and deformation.

[0025] Then, the cooling circulation system is activated and molding pressure is maintained to promote stable shell shaping. After mold closing and lateral pressure application, the water pump 20 in the water tank 19 is activated. The water pump 20 draws cooling water from the water tank 19 through the suction pipe 22 and delivers it to the die cavity body 12 through the outlet pipe 21. The cooling water flows inside the die cavity body 12, quickly absorbing the heat generated during molding, and then returns to the water tank 19 through the return channel, forming a complete cooling cycle. The operator needs to monitor the operating status of the cooling system in real time, observe the changes in cooling water temperature, and add new cooling water through the inlet 23 if necessary to ensure stable cooling effect. At the same time, the hydraulic cylinder 18 continuously maintains the mold closing pressure, and the side pressure component 8 also maintains lateral auxiliary pressure, so that the shell is always in a stable pressure environment during the cooling process, avoiding dimensional deviations or deformation of the shell due to pressure relaxation or uneven cooling. According to the characteristics of the shell material, a reasonable cooling time is set to ensure the complete stability of the internal structure of the shell.

[0026] Finally, after cooling, the mold opening and part removal operations are performed, and the mold is cleaned and maintained. When the cooling time reaches the preset requirement and the shell is fully formed, the hydraulic cylinder 18 drives the upper mold base 3 to move the upper module 5 upward, gradually separating it from the lower module 4, and the mold body 16 detaches from the shell. During the mold opening process, the rising speed of the upper module 5 is controlled to avoid the shell sticking to or being damaged by excessive speed. After the upper module 5 moves to the designated position, the telescopic rod 6, with the help of the elastic action of the return spring 7, drives the protective box 9 and the extrusion plate 10 back to the initial position. The staff carefully removes the formed shell using special tools, checks the appearance quality of the shell, including flatness, contour accuracy, and whether there are scratches on the surface, and records the reasons for the problems of unqualified products for subsequent optimization. After the part is removed, the residual waste and impurities in each part of the mold are cleaned, the surface dust is blown away with compressed air, and stubborn stains are wiped clean with special cleaning agent; the silicone pad 13 is checked for wear, and if damaged, it is replaced in time; at the same time, the working performance of the telescopic rod 6, return spring 7, cylinder 11 and other components is checked to ensure that there is no jamming or damage. Finally, turn off the system power and properly dispose of the remaining cooling water in the water tank 19 to prepare for the next mold operation.
