Description

Technical Field

[0001] The utility model relates to the field of molds, in particular to a cutting and stabbing integrated hardware mold. Background Art

[0002] The die-cutting industry processes a lot of products with holes, which are mainly processed by engraving die waste suction, metal die punching and engraving die waste discharge. However, each of the above processes has its drawbacks. For example, the inner holes of products cut by the engraving die waste suction process have problems of embossing and crushing, and are prone to knife collapse and unclean waste discharge; metal die punching has edge hair problems for softer and thicker materials, and the price is high and the delivery time is long; and the engraving die waste discharge process will cause waste to fly around when cutting some materials, affecting the waste discharge of the next step, and easily causing poor die cutting in the subsequent process.

[0003] At present, there is no good way to universally solve the waste removal problem of almost all types of materials, so as to ensure both the inner hole cutting effect and the waste removal effect; in addition, for some materials, the three existing processes cannot meet the requirements.

[0006] In some embodiments, the blades and the waste punches are arranged in two rows. The advantage is that the position distribution of multiple blades and waste punches is described, and they can also be arranged in other positions according to processing needs.

[0007] In some embodiments, two rows of positioning punches extend from the bottom surfaces of both sides of the upper template, respectively. The advantage of this is that the positioning punches can be used to position the waste of the lower template.

[0008] In some embodiments, two rows of positioning pins extend from the bottom surfaces of both sides of the upper template, respectively. The advantage of this is that the positioning pins can be used to position the installation of the engraving mold.

[0009] In some embodiments, the engraving die has a countersunk hole in the center, which is advantageous in that the engraving die can be mounted using screws through the countersunk hole.

[0010] In some embodiments, the engraving die has a plurality of nesting holes, which is beneficial in that the engraving die can be precisely nested and installed through the nesting holes. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 1-4 As shown, the mold mainly includes an upper template 10, a lower template 20 and an engraving mold 30, wherein the upper template 10, the lower template 20 and the engraving mold 30 are all roughly rectangular, the upper template 10 is installed on the top, the engraving mold 30 is fixedly installed on the bottom of the upper template 10, the lower template 20 is fixed directly below the upper template 10 and the engraving mold 30, and the upper template 10, the lower template 20 and the engraving mold 30 can be molded together for processing.

[0020] The engraving die 30 has a plurality of blades 31, which are annular and can be used to cut the inner hole of the product; and the bottom of the upper die plate 10 has a plurality of waste punches 11, and each waste punch 11 extends into each blade 31. The positions of each blade 31 and each waste punch 11 are specifically set according to the processing conditions, and preferably, they are generally arranged in two rows.

[0021] There are a plurality of waste holes 21 on the lower mold plate 20, and the positions of the waste holes 21 correspond to the blades 31 and the waste punches 11. The size of the waste holes 21 is smaller than the blades 31 and larger than the waste punches 11, and after the mold is closed, the waste punches 11 are located directly above the center of the waste holes 21, and the blades 31 are located directly above the periphery of the waste holes 21.

[0022] Two rows of positioning punches 12 extend from the bottom surfaces of both sides of the upper template 10, and corresponding positioning punches (not shown in the figure) are also provided on the lower template 20, so as to coordinate with the positioning of the mold closing and punching waste.

[0023] In addition, two rows of positioning pins 13 extend from the top surfaces on both sides of the upper template 10, and corresponding positioning holes (not shown in the figure) are also provided on the lower template 20, so as to coordinate with the mold closing and waste positioning and ensure that the material strip can run straight and the step distance is stable.

[0024] A countersunk hole 32 is provided at the center of the engraving die 30 , and the engraving die 30 can be stably fixed on the upper die from the top surface using screws through the countersunk hole 32 .

[0025] The engraving die 30 is also provided with a plurality of nesting holes 33 , and the upper die plate 10 is also provided with corresponding nesting rods (not shown in the figure), which can cooperate with the installation of the engraving die 30 for further precise positioning.

[0026] When using the mold, first nest the engraving mold 30 on the upper mold plate 10 and tighten it with screws, then place the lower mold plate 20 directly below the engraving mold 30 and the upper mold plate 10, and make each waste punching needle 11 correspond to each waste hole 21.

[0027] like Figure 5-6 As shown, when the mold is used, the raw material 40 to be processed is conveyed to the lower mold plate 20 through the material belt, and then the mold is closed for processing. When the mold is closed, the blade 31 on the engraving mold 30 falls to cut the raw material 40 and cut out the inner hole. At this time, the waste punching needle 11 on the upper diaphragm plate can punch the cut waste 41 into the waste hole 21 on the lower diaphragm plate, so that the waste 41 is discharged through the waste hole 21.

[0028] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
