Description

Technical Field

[0001] This application relates to the field of composite mold technology, and more specifically, to a cutting and punching composite mold. Background Technology

[0002] Molds are tools used in industrial production to shape articles. By applying pressure, heat, or other forces to raw materials, they cause physical or chemical changes to produce parts or products with predetermined shapes and functions. Molds can be classified into metal forming molds and non-metal forming molds according to the forming material, into single-process, compound, and progressive molds according to their process functions and structures, into automotive and electronics molds according to their application fields, and into precision and large molds according to their accuracy and technical difficulty.

[0003] The patent with publication number CN222643001U discloses a composite mold for edge trimming and punching. Through the interaction of structures such as positioning post, first spring, stamping layer, edge trimming layer, progressive post and second spring, the stamping and edge trimming operations can be completed respectively through the progressive descent effect of the top mold and the middle mold. In addition, with the punching post in the punching assembly, the processing can be completed in one go, saving processing steps and reducing costs. It has a good forming effect and practicality.

[0004] Although the patent can complete the stamping and trimming operations, after the stamping is completed, the stamped product will remain in the lower die holder, requiring manual removal of the product from the lower die, which can easily lead to safety accidents such as pinching and collision injuries. Utility Model Content

[0005] To address the aforementioned problems, this application provides a composite die for edge trimming and punching.

[0006] The technical solution of the edge trimming and punching composite mold provided in this application is as follows:

[0007] A composite die for cutting edges and punching includes a base, a top seat on the top of the base, a lower die on the top of the base, and an ejection assembly below the lower die.

[0008] The ejection assembly includes a top plate, and there are two top plates. The base has a cavity inside, and a connecting rod is slidably connected inside the cavity. Both top plates are fixedly connected to both ends of the connecting rod. The connecting rod has two threaded sections inside, and a moving rod is fixedly connected to the bottom end of each of the two threaded sections. The base has two disassembly cavities inside.

[0009] Through the above technical solutions, the ejection component enables the automatic ejection of products from the stamping template, which significantly improves material handling efficiency, shortens the production cycle, and replaces manual operation with mechanical transmission, avoiding personnel contact with the inside of the mold and greatly reducing safety risks such as pinching and collision injuries.

[0010] Furthermore, springs are fitted at one end of each of the two moving rods located in the disassembly cavity, and connecting blocks are fixedly connected to the bottom ends of each of the two moving rods. The two ends of the two springs respectively contact the disassembly cavity and the connecting blocks.

[0011] Furthermore, the cavity is internally connected to a cam for rotation, and a geared motor is provided at one end of the disassembly cavity, with the output end of the geared motor fixedly connected to the cam.

[0012] Furthermore, the base is equipped with a stamping template at the top, and both top plates are slidably connected to the stamping template.

[0013] Furthermore, a top seat is fixedly connected to the top of the base, and a cylinder is provided on the top of the top seat. The output end of the cylinder is fixedly connected to the upper mold.

[0014] Furthermore, the upper mold has a stamping cavity inside, and multiple punching posts are fixedly connected to the outer wall of the stamping cavity. A cutting edge ring is provided on the outer side of the stamping cavity, and the cutting edge ring is fixedly connected to the upper mold.

[0015] Through the above technical solution, the punching column and the blanking groove cooperate to complete the punching in one stamping stroke, and the cutting ring completes the cutting at the same time. This changes the traditional step-by-step operation mode of the equipment, improves the processing efficiency, and reduces the process connection time.

[0016] Furthermore, the stamping template has multiple blanking slots inside, and multiple punched columns are inserted into the corresponding blanking slots.

[0017] Furthermore, the base has multiple connecting holes inside, each of which is connected to a corresponding material discharge chute.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] (1) By setting the ejection component, this utility model realizes the automatic ejection of products from the stamping template, which significantly improves the material handling efficiency, shortens the production cycle, and replaces manual operation with mechanical transmission, avoiding personnel contact with the inside of the mold and greatly reducing safety risks such as pinching and collision.

[0020] (2) This utility model achieves integrated composite processing of punching and trimming by using a cylinder to drive the upper mold to move synchronously with the punching column and the trimming ring. In one punching stroke, the punching column and the blanking groove work together to complete the punching, and the trimming ring completes the trimming synchronously. This changes the traditional step-by-step operation mode of the equipment, improves processing efficiency, and reduces the process connection time. Attached Figure Description

Detailed Implementation

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figures 1-6 A composite die for cutting edges and punching holes includes a base 1, a top seat 2 on the top of the base 1, a lower die 3 on the top of the base 1, and an ejection assembly below the lower die 3.

[0030] The ejection assembly includes a top plate 12, and there are two top plates 12. The base 1 has a cavity inside, and a connecting rod 13 is slidably connected inside the cavity. The two top plates 12 are fixedly connected to both ends of the connecting rod 13. The connecting rod 13 has two threaded sections 18 inside, and a moving rod 14 is fixedly connected to the bottom end of each of the two threaded sections 18. The base 1 has two disassembly cavities inside.

[0031] When the stamping is complete and material needs to be removed, the geared motor 19 is started via an external control button. Its output end drives the cam 17 to rotate inside the cavity. During the rotation of the cam 17, the connecting rod 13 is pushed. The connecting rod 13 slides inside the cavity and drives the top plates 12 at both ends to slide synchronously. At this time, the spring 15 is compressed, thereby realizing the ejection action of the top plate 12 against the stamping template 9. After the stamping is completed, the geared motor 19 drives the cam 17 to continue rotating. The spring 15 rebounds, causing the moving rod 14 and the connecting rod 13 to reset. The top plate 12 returns to its initial position, completing one ejection cycle.

[0032] When the cam 17 rotates to the vertical position, the top plate 12 is at its highest position. When the cam 17 is not in contact with the connecting rod 13, the top plate 12 will be located inside the stamping template 9.

[0033] During stamping, cam 17 is in Figure 5 As shown in the figure, when in this position, the top of the top plate 12 is flush with the stamping template 9.

[0034] By setting the ejection component, the stamping template 9 can automatically eject the product, which significantly improves the material handling efficiency, shortens the production cycle, and replaces manual operation with mechanical transmission, avoiding personnel contact with the inside of the mold and greatly reducing safety risks such as pinching and collision.

[0035] Reference Figures 4-6 Two movable rods 14 are each fitted with a spring 15 at one end of the disassembly cavity, and a connecting block 16 is fixedly connected to the bottom end of each movable rod 14. The two ends of the two springs 15 are respectively in contact with the disassembly cavity and the connecting block 16.

[0036] When the spring 15 loses its elasticity, rotate the connecting block 16 to disengage the moving rod 14 from the connecting rod 13. Since the spring 15 is in contact with the disassembly cavity and the connecting block 16, and is not fixedly connected, the spring 15 can rotate synchronously with the connecting block 16 when the moving rod 14 rotates. When the moving rod 14 disengages, the spring 15 can be disengaged for replacement.

[0037] Reference Figures 4-6 The cavity is rotatably connected to a cam 17. One end of the disassembly cavity is equipped with a reduction motor 19. The output end of the reduction motor 19 is fixedly connected to the cam 17. The top of the base 1 is equipped with a stamping template 9. Both top plates 12 are slidably connected to the stamping template 9.

[0038] Reference Figures 1-3The top of the base 1 is fixedly connected to the top seat 2. The top of the top seat 2 is equipped with a cylinder 5. The output end of the cylinder 5 is fixedly connected to the upper mold 4. The upper mold 4 is equipped with a stamping cavity 6. The outer wall of the stamping cavity 6 is fixedly connected with multiple punching posts 7. The outer side of the stamping cavity 6 is equipped with a cutting edge ring 8. The cutting edge ring 8 is fixedly connected to the upper mold 4. The stamping template 9 is equipped with multiple blanking grooves 10. The multiple punching posts 7 are respectively inserted into the corresponding blanking grooves 10. The base 1 is equipped with multiple connecting holes 11. The multiple connecting holes 11 are respectively connected to the corresponding blanking grooves 10.

[0039] When the mold is working, the cylinder 5 is activated, and its output end drives the upper mold 4, which is fixedly connected to it, to move downward. Multiple punching pins 7 on the outer wall of the stamping cavity 6 inside the upper mold 4 are inserted into the corresponding blanking grooves 10 inside the stamping template 9 to perform punching operations on the workpiece placed on the stamping template 9; at the same time, the trimming ring 8 on the outer side of the stamping cavity 6 moves down synchronously with the upper mold 4 to trim the workpiece.

[0040] The waste generated from punching is discharged through the discharge groove 10 in the stamping template 9 and the connecting hole 11 in the base 1, realizing the automatic collection and cleaning of waste.

[0041] The waste generated during trimming will then be discharged along the outer side of the stamping die 9, because the outer side of the stamping die 9 is inclined (e.g., Figure 5 As shown in the figure, after the cutting ring 8 completes the cutting operation on the workpiece, the scrap separates from the workpiece. The scrap, which has lost its support, slides down the inclined outer surface of the stamping template 9 under its own gravity and falls into the discharge groove at the bottom of the stamping template 9. Since the discharge groove is existing technology, it is not shown in the figure.

[0042] Working principle: First, the workpiece is placed on the stamping template 9. At this time, the cam 17 is in the initial position, and the top of the top plate 12 is flush with the stamping template 9, which does not affect the workpiece positioning. Then, the operator starts the cylinder 5 through the external control equipment. The output end of the cylinder 5 drives the upper mold 4 to move downward. The punching post 7 on the outer wall of the stamping cavity 6 in the upper mold 4 is precisely inserted into the blanking groove 10 of the stamping template 9. At the same time, the trimming ring 8 on the outer side of the stamping cavity 6 moves down synchronously, completing the combined processing of punching and trimming on the workpiece. The generated waste is discharged through the blanking groove 10 and the connecting hole 11 respectively.

[0043] After processing, cylinder 5 drives the upper mold 4 to move upward and reset. At this time, the operator presses the external control button to start the reduction motor 19. The reduction motor 19 drives the cam 17 to rotate inside the cavity. During the rotation of the cam 17, the connecting rod 13 slides inside the cavity, thereby driving the top plates 12 at both ends to move upward synchronously, compressing the spring 15, realizing the ejection action of the top plate 12 against the stamping template 9, and ejecting the stamped workpiece for material removal. When the cam 17 rotates to the vertical position, the top plate 12 reaches the highest position, completing the ejection. After material removal, the reduction motor 19 continues to drive the cam 17 to rotate. When the cam 17 is no longer in contact with the connecting rod 13, the spring 15 rebounds, pushing the moving rod 14 and the connecting rod 13 to reset. The top plate 12 retracts into the stamping template 9, returning to the initial state, waiting for the next stamping cycle. If the spring 15 loses its elasticity, the moving rod 14 can be disengaged from the connecting rod 13 by rotating the connecting block 16, realizing the quick disassembly and replacement of the spring 15, ensuring the continuous and stable operation of the ejection assembly.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
