Description

Technical Field

[0001] This utility model relates to the field of molding molds and processing equipment, and in particular to an automatic positioning molding mold for supports. Background Technology

[0002] The automatic positioning and forming mold for supports is a high-efficiency and precision industrial mold. It adopts automation technology and a precise positioning system, which can quickly and accurately position and form support components during the production process. The mold is equipped with high-precision sensors and servo drive devices, which can monitor and adjust forming parameters in real time to ensure product dimensional accuracy and consistency.

[0003] The automatic positioning and ejection device for support molds is a key component for ensuring smooth demolding of the finished product. This device typically consists of ejector pins, ejector rods, an ejector plate, and a drive mechanism, powered by hydraulic, pneumatic, or mechanical transmission. During operation, the drive mechanism pushes the ejector plate, causing the ejector pins or ejector rods to move synchronously, smoothly ejecting the molded support product from the mold cavity and preventing product deformation or damage.

[0004] When the automatic positioning forming mold ejection device for the support cannot eject the support completely and accurately, it is because the layout of the ejector pins or ejector rods is unreasonable or the number is insufficient, resulting in uneven force and causing the support to stick to the mold in some areas, making it difficult to remove. Therefore, an automatic positioning forming mold for the support is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic positioning and forming mold for supports, which aims to improve the problem that the support cannot be ejected completely and accurately in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic positioning and forming mold for a support includes a base. A second hydraulic cylinder is fixedly connected inside the base. A push plate is fixedly connected to the drive end of the second hydraulic cylinder. A pin is fixedly connected to the top of the push plate. Two push rods are fixedly connected to the top of the push plate. A follower plate is slidably connected inside the base. Two push rods are fixedly connected to the top of the follower plate. Two spring blocks are slidably connected to the outer wall of the pin. A slot is opened inside the base. A positioning and shock absorption assembly is provided on the top of the base.

[0008] As a further description of the above technical solution:

[0009] The positioning and shock absorption assembly includes a limiting post, the outer wall of which is fitted with a spring, a movable plate is slidably connected to the outer wall of which, and the bottom of which is fixedly connected to the top of the base.

[0010] As a further description of the above technical solution:

[0011] The top of the base is fixedly connected to multiple support columns, the top of the support columns is fixedly connected to a top plate, and the top of the top plate is fixedly connected to a hydraulic cylinder.

[0012] As a further description of the above technical solution:

[0013] A movable plate is fixedly connected to the drive end of the hydraulic cylinder one. A hydraulic push rod is fixedly connected inside the movable plate. A follower block is rotatably connected to the drive end of the hydraulic push rod. A locking pin is rotatably connected to the inner wall of the follower block. A connecting plate one is rotatably connected to the outer wall of the locking pin. A connecting plate two is rotatably connected to the outer wall of the connecting plate one. A fixed block is rotatably connected to the other end of the connecting plate one. A punch is movably connected to the outer wall of the locking pin.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the first push rod is slidably connected to the inside of the base, and the outer wall of the second push rod is slidably connected to the inside of the base;

[0016] As a further description of the above technical solution:

[0017] The outer wall of the push plate is slidably connected to the inside of the base, and one end of the connecting plate is rotatably connected to the bottom of the fixed block;

[0020] As a further description of the above technical solution:

[0021] The outer wall of the spring block is in contact with the inner wall of the follower plate, and the outer wall of the spring block is in contact with the slot.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the second hydraulic cylinder pushes the push plate to move upward, and the first ejector rod fixed on the plate rises accordingly. At the same time, the pin also moves upward. The tip of the pin cooperates with the spring block, and the follower plate slot locks the spring block. The pin moves upward and lifts the spring block, causing the second ejector rod at the top of the follower plate to rise. Together with the first ejector rod, the first ejection is completed, allowing the support to initially separate from the cavity. As the pin continues to move upward, the spring block is pushed into the slot of the base. The pin continues to move, driving the follower plate to move upward again, realizing the second ejection, and ensuring that the support is completely demolded.

[0024] 2. In this utility model, the punch is prone to wear and needs to be replaced after long-term use. When the hydraulic push rod is activated and retracted, it drives the connecting plate two and the follower block to move synchronously. The connecting plate two then pulls the connecting plate one, and the two form a pulling force combination, driving the locking pin to move down and releasing the locking and fixing of the punch. Through this mechanical linkage, the operator can quickly complete the replacement of the punch, effectively improving the mold maintenance efficiency and extending the service life of the mold.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2This utility model provides an embodiment of an automatic positioning and forming mold for a support, comprising a base 1. A second hydraulic cylinder 8 is fixedly connected inside the base 1. A push plate 9 is fixedly connected to the drive end of the second hydraulic cylinder 8. The outer wall of the push plate 9 is slidably connected to the inside of the base 1, achieving smooth and precise linear motion. A pin 10 is fixedly connected to the top of the push plate 9. Two push rods 13 are fixedly connected to the top of the push plate 9. The outer walls of the push rods 13 are slidably connected to the inside of the base 1. The push rods 13 slide along a preset slide rail on the base 1 to ensure precise movement. Driven by the push plate 9, an upward thrust can be applied to the formed support. A follower plate 12 is slidably connected inside the base 1. Two push rods 14 are fixedly connected to the top of the follower plate 12. The outer walls of the push rods 14 are slidably connected to the inside of the base 1. The follower plate 12 slides within the base 1, with the two push rods 14 fixed to the top of the follower plate 12. Working in conjunction with the push rod 13, a multi-point support ejection structure is formed. Two spring blocks 11 are slidably connected to the outer wall of the pin 10. The outer wall of the spring block 11 contacts the inner wall of the follower plate 12 and the outer wall of the spring block 11 contacts the slot 15. The slot 15 is provided inside the base 1. As the pin 10 continues to move upward, the spring block 11 is pushed into the slot 15 of the base 1. The pin 10 continues to move, driving the follower plate 12 to move upward again, realizing secondary ejection. The top of the base 1 is provided with a positioning and shock absorption component, which includes a limiting post 5. The top of the limiting post 5 is fixedly connected to the bottom of the top plate 3. A spring 7 is sleeved on the outer wall of the limiting post 5. A moving plate 6 is slidably connected to the outer wall of the limiting post 5. The bottom of the limiting post 5 is fixedly connected to the top of the base 1. The moving plate 6 can slide up and down along the limiting post 5. The spring 7 absorbs and buffers the impact force through compression and rebound, preventing the moving plate 6 from rebounding quickly and causing damage to the device.

[0033] Reference Figure 3 and Figure 4The top of the base 1 is fixedly connected to multiple support columns 2. The top of the support columns 2 is fixedly connected to a top plate 3. The top of the top plate 3 is fixedly connected to a hydraulic cylinder 4. The drive end of the hydraulic cylinder 4 is fixedly connected to a moving plate 6. When the hydraulic cylinder 4 is activated, it pushes the moving plate 6 to move linearly along the direction of the limit column 5. The inside of the moving plate 6 is fixedly connected to a hydraulic push rod 20. The drive end of the hydraulic push rod 20 is rotatably connected to a follower block 19. When the hydraulic push rod 20 is activated, the rotatably connected follower block 19 converts the linear motion into flexible multi-angle motion. The inner wall of the follower block 19 is rotatably connected to a locking pin 21. The outer wall of the locking pin 21 is rotatably connected to a connecting plate 17. The outer wall of the connecting plate 17 rotates... A connecting plate 218 is connected. The hydraulic push rod 20 drives the follower block 19 to rotate, and at the same time drives the connecting plate 218 to move. The connecting plate 218 converts the linear retraction force of the hydraulic push rod 20 into a pulling force on the connecting plate 17, and transmits the pulling force to the locking pin 21. The other end of the connecting plate 17 is rotatably connected to the fixing block 16. The top of the fixing block 16 is fixedly connected to the inside of the moving plate 6. The fixing block 16 is installed inside the moving plate 6 and acts as a fulcrum. The outer wall of the locking pin 21 is movably connected to the punch 22. Under the action of the pulling force, the locking pin 21 moves downward along the preset motion trajectory, and the structure that is tightly engaged with the punch 22 is gradually released. One end of the connecting plate 17 is rotatably connected to the bottom of the fixing block 16.

[0034] Working principle: The operator activates hydraulic cylinder 4, which pushes the moving plate 6 downwards vertically. Thanks to its precise guiding structure, the moving plate 6 remains stable during descent, simultaneously driving the punch 22 to precisely press down onto the surface of the base 1. Once the support is formed, hydraulic cylinder 4 retracts, pulling the moving plate 6 upwards in the opposite direction. Two limiting posts 5 running through the moving plate 6, together with springs 7, form a double protection system. The limiting posts 5 constrain the movement trajectory of the moving plate 6, while the springs 7 absorb impact through elastic deformation, achieving positioning and shock absorption.

[0035] Hydraulic cylinder 28 is activated, which pushes push plate 9 upward. Push plate 9 is fixed with ejector rod 13. As ejector rod 13 moves upward, push plate 9 is also fixed with pin 10. The top of pin 10 is pointed. A specially designed groove inside follower plate 12 precisely locks spring block 11. When pin 10 moves upward, spring block 11 is lifted by the force of the inclined surface at the tip. At the top of follower plate 12 is ejector rod 24. Ejector rod 24 at the top of follower plate 12 rises accordingly and works with ejector rod 13 to complete the first ejection action, initially separating the molded support from the cavity. Ejector rod 24 moves upward synchronously to achieve one ejection. As pin 10 moves upward, it drives spring block 11 to move upward. Spring block 11 moves upward to the fixed position. The base 1 has a slot 15. Spring block 11 is pushed into the slot 15. Pin 10 continues to move upward, driving follower plate 12 to move upward to achieve a second ejection, ensuring that the support is completely demolded.

[0036] The punch 22 will wear out after prolonged use and needs to be replaced. Activating the hydraulic push rod 20 causes it to retract, which drives the connecting plate 28 and the follower block 19 to move synchronously. The connecting plate 28 pulls the connecting plate 17, creating a pulling force combination that drives the locking pin 21 downwards, releasing the locking of the punch 22. This allows operators to quickly replace the punch 22, greatly improving the maintenance efficiency and service life of the mold.

[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.
