Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a demolding auxiliary device for molds. Background Technology

[0002] Demolding aids are an important technical means to improve mold forming efficiency, reduce product damage, and improve production quality. With the continuous development of mold manufacturing technology, demolding aids are becoming more and more diversified. Combined with different production processes and material characteristics, they can effectively improve production efficiency and product quality.

[0003] Existing mold release aids include the following common types: pneumatic release devices, mechanical release devices, electric release devices, vibration release devices, thermal expansion and contraction release devices, and hydraulic release devices. The appropriate release method is often selected based on the difficulty of release, production efficiency, and cost.

This is especially true for parts with complex shapes or high precision requirements. Excessive friction not only affects demolding efficiency but can also damage the mold and the molded part. Therefore, a mold release aid is proposed to solve the above problems. Utility Model Content

Two side plates 2 are fixedly connected to the top of the base plate 1. The two side plates 2 provide additional support, which can improve the robustness of the entire device and prevent shaking during operation. A fixing plate 3 is fixedly connected to the top of the two side plates 2. The function of the fixing plate 3 is to provide a fixing platform for the upper components, ensuring that the structure of the device is more stable and preventing the components from shifting due to vibration. A mold base fixing block 13 is fixedly connected to the top of the fixing plate 3. A baffle 14 is fixedly connected to one side of the inner wall of the mold base fixing block 13. A motor 15 is fixedly connected to the top of the baffle 14. The function of the baffle 14 is to fix the motor 15. The motor 15 is the power source of the demolding component and can provide power for the subsequent demolding work.

[0033] A circular plate 27 is fixedly connected to the drive end of motor 15. The circular plate 27 is an intermediate component for motion transmission. A rotating rod 16 is rotatably connected to one side of the circular plate 27. A push rod 17 is rotatably connected to one end of the rotating rod 16. The push rod 17 and the rotating rod 16 convert rotational motion into linear pushing force, which is an important component for pushing open the mold during demolding, ensuring that the molded part is ejected from the mold. A fixed rod 18 is slidably connected to the outer wall of the push rod 17. An ejector 19 is fixedly connected to one end of the push rod 17. The ejector 19 is in direct contact with the workpiece and is responsible for pushing the workpiece out of the mold, ensuring that the item in the mold is smoothly ejected and avoiding jamming or damage. A lower mold base 20 is slidably connected to one side of the mold base fixing block 2 13. The lower mold base 20 can slide on the inner wall of the mold base fixing block 2 13, so that the base of the mold can be adjusted according to the needs to adapt to different specifications of molds and improve the flexibility of demolding. A detachable component is provided on the top of the fixing plate 3, and a feeding component is provided on the top of the base plate 1.

[0034] Reference Figure 1 , Figure 2 and Figure 4The detachable components include a hydraulic telescopic joint 5, which provides power for the stamping of the device. A die base fixing block 7 is fixedly connected to the drive end of the hydraulic telescopic joint 5. A slider 6 is fixedly connected to the bottom of the die base fixing block 7, serving as a guide to ensure the smooth operation of the entire device. Two sliding rods 4 are slidably connected to the inner wall of the slider 6, providing support and guidance to ensure stable movement. An upper die base 8 is slidably connected to one side of the die base fixing block 7. A retainer housing 9 is fixedly connected to the top of the die base fixing block 7, protecting the internal components and providing structural support. Two springs 10 are fixedly connected to the inner wall of the retainer housing 9, providing reaction force to maintain the tension and balance of the components. A top plate 11 is fixedly connected, and a stop block 12 is fixedly connected to one side of the top plate 11. The stop block 12 can fix the position of the upper die base 8 and prevent the upper die base 8 from shaking during the stamping process. The unloading assembly includes a second baffle 21. A second motor 22 is fixedly connected to the top of the second baffle 21. A drive wheel 23 is fixedly connected to the drive end of the second motor 22. The drive wheel 23 controls the material conveying by driving the transmission device. Driven wheels 25 are rotatably connected to the adjacent sides of the two side plates 2. A belt 24 is coupled to the outer wall of the drive wheel 23 and the driven wheel 25. The belt 24 transmits power from the drive wheel 23 to the driven wheel 25, thereby driving the unloading process. Two unloading plates 26 are provided on both sides of the inner wall of the fixed plate 3. The unloading plates 26 are used to limit the sliding of the ejected workpiece and ensure that the workpiece falls smoothly to the designated position.

[0035] Working principle: By starting motor 15, the drive end of motor 15 can drive the circular plate 27 to rotate. The rotation of the circular plate 27 can drive the rotating rod 16 to swing. The swing of the rotating rod 16 can drive the push rod 17 to move horizontally. The fixed rod 18 can limit the movement range of the push rod 17 to prevent the push rod 17 from moving excessively. The movement of the push rod 17 can drive the ejector 19 to move. The ejector head of the ejector 19 can slide in the inner wall of the fixed plate 3 and the lower die base 20. When the die stamping is completed, starting motor 15 can eject the workpiece on the lower die base 20.

[0036] During die stamping operations, different die models can be replaced. By pressing the stop block 12, the stop block 12 can drive the top plate 11 to move. The movement of the top plate 11 can compress the spring 10 to retract inward. When the stop block 12 is pushed into the interior of the retainer housing 9, the upper die holder 8 can be removed for replacement. After replacement, the stop block 12 can be ejected by the spring 10 to lock the upper die holder 8, preventing the upper die holder 8 from shaking during die stamping, which would result in insufficient die stamping precision. By activating the hydraulic telescoping device 5, the hydraulic telescoping device 5... The drive end can drive the slider 6 and the die holder fixing block 7 to slide on the two slide rods 4, so that the upper die holder 8 can be combined with the lower die holder 20 to perform stamping work. When the stamping operation is finished, the workpiece ejected by the ejector 19 will slide down the two blanking plates 26 onto the belt 24. By starting the motor 22, the drive end of the motor 22 can drive the drive wheel 23 to rotate. The rotation of the drive wheel 23 can drive the belt 24 to rotate, thereby conveying the workpiece, which is convenient for the workers to transport and reduces the risk of manual operation.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
