Description

Technical Field

[0001] This utility model relates to the technical field of molds, specifically to a punching die that is easy to adjust. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, molds are tools used to make shaped objects. These tools are composed of various parts, and different molds are composed of different parts. They mainly achieve the processing of the shape of the object by changing the physical state of the material being molded. They are known as the "mother of industry." They are tools that make blanks into parts with specific shapes and sizes under the action of external forces. They are widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. Punching dies are molds for punching products.

[0003] In the existing technology, the die core, die base, and connecting plate in the punching die are fixedly connected by screws. The die core can only process parts of one shape. When it is necessary to process parts of different sizes, both the upper and lower die cores need to be replaced, which is cumbersome, time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to provide an easily adjustable punching die. By adjusting the upper die core, parts of different sizes can be processed without replacement, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides an easily adjustable punching die, comprising a moving die assembly and a fixed die assembly. The moving die assembly includes a top plate, an upper template, and an upper die core. The upper die core includes a first die core, a second die core, and an adjusting screw. The first die core and the second die core are symmetrically arranged. The upper template is located at the bottom of the top plate and has a sliding groove. The first die core and the second die core are slidably connected to the sliding groove. The adjusting screw connects the first die core and the second die core. One section of the adjusting screw has a positive thread, and the other section has a negative thread. The positive thread is threaded to the first die core, and the negative thread is threaded to the second die core. The fixed die assembly includes a bottom plate and a lower die core. The lower die cores are in multiple groups, each group having a different size, and each group of lower die cores is arranged at the same height.

[0006] Furthermore, a first locking nut is provided on one end of the adjusting screw, and a second locking nut is provided on the other end of the adjusting screw. The first locking nut abuts against the first mold core, and the second locking nut abuts against the second mold core.

[0007] Furthermore, the base plate is provided with a processing position and a placement position. The lower mold core to be used is placed in the processing position, and the remaining lower mold cores are placed in the placement position.

[0008] Furthermore, both the processing position and the placement position are provided with positioning posts, and the lower mold core is provided with positioning holes that are adapted to the positioning posts.

[0009] Furthermore, the machining position is provided with a locking stud, which abuts against the lower mold core on the machining position.

[0010] Furthermore, the locking studs are provided on both sides of the processing position, and the base plate is provided with a support block, with the locking studs threadedly connected to the support block.

[0011] Furthermore, the support blocks are in two sets and are respectively disposed on both sides of the lower mold core, forming a placement cavity between the two sets of support blocks, with one end of the placement cavity being open.

[0012] Furthermore, the punching die also includes a guide post assembly, which is disposed on the base plate. The top plate is provided with a guide hole, through which the guide post assembly passes, and the guide hole is slidably connected to the guide post.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Before machining a part, select a suitable lower die and install it in the designated position. Then, adjust the distance between the first and second die cores by rotating the adjusting screw to ensure the upper and lower die cores are properly matched. The moving die assembly can then be activated for the punching operation. When machining a second type of part, replace the lower die core. Again, adjust the distance between the first and second die cores by rotating the adjusting screw to ensure the upper and lower die cores are properly matched. The moving die assembly can then be activated for the punching operation. When machining parts of different sizes, only the lower die core needs to be replaced and the upper die core adjusted. This simple operation improves machining efficiency.

[0015] 2. The base plate has a machining position and a placement position. The lower mold core to be used is placed in the placement position, and the remaining lower mold cores are placed in the placement position. The machining position is equipped with a locking stud. After the locking stud is rotated, it can abut against the lower mold core on the machining position to fix the lower mold core.

[0016] 3. The punching die also includes a guide post assembly, which is located on the base plate. A guide hole is provided on the top plate, through which the guide post assembly passes, and the guide hole is slidably connected to the guide post. By setting the guide post, the movement direction of the moving die assembly can be limited, allowing for precise docking between the moving die assembly and the fixed die assembly.

[0027] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] Reference Figures 1 to 4 As an embodiment of this utility model, an easily adjustable punching die includes a moving die assembly 1 and a fixed die assembly 2. The moving die assembly 1 includes a top plate 11, an upper template 12, and an upper die core 13. The upper die core 13 includes a first die core 131, a second die core 132, and an adjusting screw 133. The first die core 131 and the second die core 132 are symmetrically arranged. The upper template 12 is located at the bottom of the top plate 11. A sliding groove 121 is provided on the upper template 12. The first die core 131 and the second die core 132 are slidably connected to the sliding groove 121. The adjusting screw 133 connects the first die core 131 and the second die core 132. One end of the adjusting screw 133 is provided with a positive thread, and the other end is provided with a negative thread. The positive thread is threaded to the first die core 131, and the negative thread is threaded to the second die core 132. The fixed die assembly 2 includes a bottom plate 21 and a lower die core 22. There are multiple sets of lower die cores 22, each set of lower die cores 22 has a different size, and each set of lower die cores 22 is set at the same height.

[0029] Before machining a part, a suitable lower die core 22 is selected and installed in the designated position. Then, the distance between the first die core 131 and the second die core 132 is adjusted by rotating the adjusting screw 133, so that the upper die core 13 matches the lower die core 22. Then, the moving die assembly 1 can be started to perform the punching operation. When a second type of part machining operation is required, the lower die core 22 is replaced. At this time, the distance between the first die core 131 and the second die core 132 is adjusted again by rotating the adjusting screw 133, so that the upper die core 13 matches the lower die core 22. Then, the moving die assembly 1 can be started to perform the punching operation. When machining parts of different sizes, only the lower die core 22 needs to be replaced and the upper die core 13 needs to be adjusted. The operation is simple and improves the machining efficiency of parts.

[0030] Specifically, a first locking nut 134 is provided on one end of the adjusting screw 133, and a second locking nut 135 is provided on the other end of the adjusting screw 133. The first locking nut 134 is connected to the positive thread end of the adjusting screw 133 and can abut against the first die core 131. The second locking nut 135 is connected to the negative thread end of the adjusting screw 133 and can abut against the second die core 132. By setting the first locking nut 134 and the second locking nut 135, the first die core 131 and the second die core 132 can be effectively fixed. There are multiple sets of lower die cores 22, each set of lower die cores 22 has a different size, and each set of lower die cores 22 is arranged adjacent to each other to save placement space. In order to avoid the lower die cores 22 interfering with the punching process of the upper die core 13 when not in use, each set of lower die cores 22 is set at the same height.

[0031] Furthermore, the base plate 21 is provided with a machining position 211 and a placement position 212. The lower mold core 22 to be used is placed in the machining position 211, and the remaining lower mold cores 22 are placed in the placement position 212.

[0032] Specifically, both the machining position 211 and the placement position 212 are provided with positioning pins 213, and the lower mold core 22 is provided with positioning holes that are adapted to the positioning pins 213. To ensure consistent installation of the lower mold core 22, the positioning pins 213 of the machining position 211 and the placement position 212 have identical structures. The machining position 211 is provided with a locking stud 23, which abuts against the lower mold core 22 on the machining position 211. The locking stud 23 abuts against the lower mold core 22 on the machining position 211, effectively fixing the lower mold core 22.

[0033] In this embodiment, locking studs 23 are provided on both sides of the machining position 211, and support blocks 24 are provided on the base plate 21. The locking studs 23 are threadedly connected to the support blocks 24. After the locking studs 23 rotate, they can abut against the lower mold core 22 on the machining position 211. Through the positioning action of the positioning pin 213 and the abutting action of the locking studs 23, the lower mold core 22 can be effectively fixed. There are two sets of support blocks 24, which are respectively arranged on both sides of the lower mold core 22. A placement cavity is formed between the two sets of support blocks 24. One end of the placement cavity is open. This structure facilitates the replacement of the lower mold core 22. Only the lower mold core 22 that needs to be machined is abutted by the locking studs 23, while the other lower mold cores 22 are fixed only by the positioning pins 213.

[0034] Furthermore, the punching die also includes a guide post 3 assembly, which is mounted on the base plate 21. The top plate 11 has a guide hole 111, through which the guide post 3 assembly passes. The guide hole 111 is slidably connected to the guide post 3. By setting the guide post 3, the movement direction of the moving die assembly 1 can be limited, so that the moving die assembly 1 and the fixed die assembly 2 can be precisely aligned.

[0035] In this embodiment, before machining the part, a suitable lower die core 22 is selected and installed in the designated position. Then, the distance between the first die core 131 and the second die core 132 is adjusted by rotating the adjusting screw 133, so that the upper die core 13 and the lower die core 22 are adapted to each other. Then, the moving die assembly 1 can be started to perform the punching operation. When a second type of part machining operation is required, the lower die core 22 is replaced. At this time, the distance between the first die core 131 and the second die core 132 is adjusted by rotating the adjusting screw 133 again, so that the upper die core 13 and the lower die core 22 are adapted to each other. Then, the moving die assembly 1 can be started to perform the punching operation. When it is necessary to machine parts of different sizes, only the lower die core 22 needs to be replaced and the upper die core 13 needs to be adjusted. The operation is simple and improves the machining efficiency of the parts.

[0036] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
