Description

Technical Field

[0001] This utility model relates to the field of mold design, and in particular to a stamping mold that can simultaneously punch and shape holes on both a plane and an inclined plane. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts.

[0003] Commercially available stamping dies typically involve placing material between an upper and lower die for stamping. After stamping, the material is pressed into the same shape as the die, enabling mass production. However, some parts require multiple punches during stamping, with some punches facing planar and others inclined. Currently, the common method for punching inclined surfaces is to use a slanted ejector pin, but this cannot simultaneously punch holes in different directions. Multiple stamping dies are needed, requiring the product to be stamped and shaped sequentially. This process involves multiple die-cutting operations, which can easily lead to defects. Furthermore, multiple stamping dies increase the production cost of parts. Therefore, it is necessary to design a structure that can simultaneously punch holes in both planar and inclined directions, based on existing stamping dies. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0005] A stamping die for simultaneously punching and shaping holes on a plane and an inclined plane includes an upper die and a lower die, wherein the upper die and the lower die are mutually engaged for stamping.

[0006] The upper mold includes a first template, a spring, a lifting plate, and an upper stamping part;

[0007] The lifting plate is located below the first template, and multiple springs are evenly arranged and installed between the first template and the lifting plate.

[0008] The upper stamping part is fixedly installed in the middle of the lifting plate. The upper stamping part includes a flat punching part, an inclined punching part and a bottom stamping part. The bottom stamping part is fixedly installed at the bottom of the lifting plate. The middle of the lifting plate is formed with an installation groove. The flat punching part and the inclined punching part are both clearance-fitted into the installation groove.

[0009] The lower ends of the planar punched part and the inclined punched part are punched in the bottom stamping part, and the upper ends of the planar punched part and the inclined punched part are fixedly installed on the bottom side of the first template.

[0010] Furthermore: the upper side of the bottom stamping part is formed with an oblique stamping groove, and the oblique stamping groove and the upper side of the bottom stamping part are both formed with first stamping holes. The first stamping holes are set through the bottom stamping part. The lower ends of the flat punching part and the oblique punching part are fixedly installed with stamping shafts, and the stamping shafts are inserted into the first stamping holes with a clearance fit to perform the punching action.

[0011] Furthermore: the inclined punching part includes an upper pressing part and a lower pressing part. The upper pressing part is fixedly installed below the first template. An inclined translation part is fixedly installed inside the lower pressing part. A first inclined surface is formed on the lower side of the upper pressing part, and a second inclined surface is formed on the upper side of the lower pressing part. The first inclined surface abuts against the second inclined surface. The lower end of the inclined translation part extends out of the lower pressing part. The lower end of the inclined translation part is inserted into the inclined punching groove with a clearance fit. The punching shaft is fixedly installed at the lower end of the inclined translation part.

[0012] Furthermore: the lower die includes a second template and a lower stamping part. The upper stamping part and the lower stamping part are matched and stamped with each other. The lower stamping part has a stamping slope and a stamping plane. The stamping slope and the stamping plane are both formed with second stamping holes. The second stamping holes are arranged one-to-one below the first stamping holes. When the upper die and the lower die are closed, the stamping shaft is inserted into the first stamping hole and the second stamping hole in sequence.

[0013] Furthermore: Several lifting blocks are fixedly installed on the bottom side of the second template, and a waste collection drawer is provided between two adjacent lifting blocks. The waste collection drawer is located below the two second punching holes.

[0014] Furthermore, a drawer handle is fixedly installed on the front side of the waste collection drawer.

[0015] Furthermore: at least four positioning guide posts are fixedly installed on the bottom side of the first template, and at least four lifting holes are formed on the lifting plate, with the positioning guide posts slidingly fitted into the lifting holes one by one.

[0016] Furthermore: Several positioning bolts are fixedly installed on the bottom side of the lifting plate, and the bottom end of the positioning bolts is provided with nuts. The number of positioning bolts is twice the number of lifting holes, and the nuts of the positioning bolts are one-to-one abutting the bottom end of the lifting holes. Limiting rings are fixedly installed on the positioning guide post, and the nuts of the positioning bolts are set to abut against the limiting rings. The nuts of the positioning bolts and the positioning guide post are staggered from each other.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: Before the upper and lower dies close together, the spring is in a taut state. At this time, the lower ends of the flat punch and the inclined punch are far away from the bottom stamping part. When the dies close, the lifting plate first presses on the material of the lower die for stamping and shaping. After stamping and shaping, the spring is compressed. At this time, the lower ends of the flat punch and the inclined punch perform punching action in the bottom stamping part, realizing the action of punching on the flat and inclined surfaces of the material at the same time, which speeds up the production efficiency. Moreover, it is not necessary to set up multiple stamping dies to punch holes in different directions, thereby reducing manufacturing costs. At the same time, the production quality of the product is higher. Since multiple stamping is not required, the probability of product wear can be reduced.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] like Figure 1-11 As shown, the present invention provides a stamping die for simultaneously punching and shaping holes on a plane and an inclined plane, comprising an upper die 1 and a lower die 2, wherein the upper die 1 and the lower die 2 are mutually engaged for stamping.

[0038] The upper mold 1 includes a first template 1.1, a spring 1.2, a lifting plate 1.3, and an upper stamping part 1.4;

[0039] The lifting plate 1.3 is located below the first template 1.1, and multiple springs 1.2 are evenly arranged and installed between the first template 1.1 and the lifting plate 1.3.

[0040] The upper stamping part 1.4 is fixedly installed in the middle of the lifting plate 1.3. The upper stamping part 1.4 includes a flat punching part 1.41, an inclined punching part 1.42 and a bottom stamping part 1.43. The bottom stamping part 1.43 is fixedly installed at the bottom of the lifting plate 1.3. The middle of the lifting plate 1.3 is formed with an installation groove 3. The flat punching part 1.41 and the inclined punching part 1.42 are both clearance-fitted into the installation groove 3.

[0041] The lower ends of the planar punched part 1.41 and the inclined punched part 1.42 are punched in the bottom stamping part 1.43, and the upper ends of the planar punched part 1.41 and the inclined punched part 1.42 are fixedly installed on the bottom side of the first template 1.1.

[0042] The principle is as follows: Before the upper mold 1 and the lower mold 2 close together, the spring 1.2 is in a taut state. At this time, the lower ends of the flat punch 1.41 and the inclined punch 1.42 are far away from the bottom stamping part 1.43. When the mold closes, the lifting plate 1.3 first presses on the material of the lower mold 2 for stamping and shaping. After stamping and shaping, the spring 1.2 is compressed. At this time, the lower ends of the flat punch 1.41 and the inclined punch 1.42 are driven to punch holes in the bottom stamping part 1.43, realizing the action of punching holes on the flat and inclined surfaces of the material at the same time. This speeds up the production efficiency and eliminates the need to set up multiple stamping dies to punch holes in different directions, thereby reducing manufacturing costs. At the same time, the production quality of the product is higher. Since multiple stamping is not required, the probability of product wear can be reduced.

[0043] Furthermore, the upper side of the bottom stamping part 1.43 is formed with an oblique stamping groove 4, and both the oblique stamping groove 4 and the upper side of the bottom stamping part 1.43 are formed with first stamping holes 5. The first stamping holes 5 penetrate the bottom stamping part 1.43. The lower ends of the planar punching part 1.41 and the oblique punching part 1.42 are fixedly installed with stamping shafts 6. The stamping shafts 6 are inserted into the first stamping holes 5 with a corresponding clearance to perform the punching action. The punching of the material can be achieved by inserting the stamping shafts 6 into the first stamping holes 5, which is convenient and fast, and can achieve punching in both planar and oblique directions at the same time, thereby speeding up production efficiency.

[0044] Furthermore: the inclined punched part 1.42 includes an upper pressing part 1.421 and a lower pressing part 1.422. The upper pressing part 1.421 is fixedly installed below the first template 1.1. An inclined translational part 18 is fixedly installed inside the lower pressing part 1.422. A first inclined surface 19 is formed on the lower side of the upper pressing part 1.421, and a second inclined surface 20 is formed on the upper side of the lower pressing part 1.422. The first inclined surface 19 abuts against the second inclined surface 20. The lower end of the inclined translational part 18 extends out of the lower pressing part 1.422. The .422 setting is configured such that the lower end of the inclined translation component 18 is inserted into the inclined stamping groove 4 with a clearance fit, and the stamping shaft 6 is fixedly installed at the lower end of the inclined translation component 18. When the upper mold 1 closes and presses down, the lower pressing component 1.422 will be driven to move along the direction of the inclined stamping groove 4 through the first inclined surface 19 and the second inclined surface 20. Therefore, the stamping shaft 6 in the inclined direction can be inserted into the corresponding first stamping hole 5 at an angle to realize the punching action in the inclined direction, which can ensure the production quality of the punching.

[0045] Furthermore: The lower die 2 includes a second template 2.1 and a lower stamping part 2.2. The upper stamping part 1.4 and the lower stamping part 2.2 are matched and stamped together. The lower stamping part 2.2 is formed with a stamping inclined surface 7 and a stamping plane 8. Both the stamping inclined surface 7 and the stamping plane 8 are formed with second stamping holes 9. The second stamping holes 9 are arranged one-to-one below the first stamping holes 5. When the upper die 1 and the lower die 2 are closed, the stamping shaft 6 is inserted into the first stamping hole 5 and the second stamping hole 9 in sequence. The setting of the second stamping holes 9 can ensure that the stamping shaft 6 can complete the stamping through the material placed on the lower die 2, thereby achieving the effect of precise punching and ensuring the quality of its punching process.

[0046] Furthermore: Several lifting blocks 10 are fixedly installed on the bottom side of the second template 2.1, and a waste collection drawer 11 is provided between two adjacent lifting blocks 10. The waste collection drawer 11 is located below the two second punching holes 9; the waste generated by punching will automatically fall into the waste collection drawer 11 for recycling, which is convenient for actual use.

[0047] Furthermore, a drawer handle 12 is fixedly installed on the front side of the waste collection drawer 11, which facilitates the removal of the waste collection drawer 11 for waste cleaning.

[0048] Furthermore: at least four positioning guide posts 13 are fixedly installed on the bottom side of the first template 1.1, and at least four lifting holes 14 are formed on the lifting plate 1.3. The positioning guide posts 13 are slidably installed in the lifting holes 14 in a one-to-one correspondence; this can effectively improve the punching accuracy and ensure stable mold closing between the upper mold 1 and the lower mold 2.

[0049] Furthermore: Several positioning bolts 15 are fixedly installed on the bottom side of the lifting plate 1.3. The bottom end of the positioning bolt 15 is provided with a nut 16. The number of positioning bolts 15 is twice the number of lifting holes 14, and the nuts 16 of the positioning bolts 15 are correspondingly pressed against the bottom end of the lifting holes 14. A limit ring 17 is fixedly installed on the positioning guide post 13. The nuts 16 of the positioning bolts 15 are set against the limit ring 17. The nuts 16 of the positioning bolts 15 and the positioning guide post 13 are staggered. The cooperation of the positioning bolts 15 and the limit ring 17 can realize the lifting stroke limit of the lifting plate 1.3, ensuring the effect of precise stamping and punching.

[0050] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
