DETAILED DESCRIPTION

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] like Figure 1-4 As shown, the mold is installed on the machine table of the die-cutting machine and is used to feed and punch the upper and lower materials to facilitate pasting. The mold mainly includes an upper module 1 and a lower module 2, wherein the upper module 1 and the lower module 2 are separated from each other, and the upper module 1 is located directly above the lower module 2.

[0019] The upper module 1 mainly includes an upper die base 11, an upper frame plate 12 and an upper stripping plate 13 which are sequentially arranged and installed from top to bottom. The top of the upper die base 11 of the upper module 1 is connected to the machine platform through a stamping structure that can move vertically.

[0020] The lower module 2 includes a lower die base 21, a lower frame plate 22 and a concave die plate 23 which are sequentially arranged from bottom to top, and the upper stripper plate 13 of the upper module 1 is located directly above the concave die plate 23 of the lower die base 21. The lower module 2 of the lower die base 21 is placed and installed on the machine platform, and a cavity 24 which is concave upward is provided on the bottom surface of the concave die plate 23.

[0021] In addition, the machine table is provided with a discharge shaft and a receiving shaft, which are respectively located above the two sides of the upper module 1. When feeding, the upper material is discharged from the discharge shaft, passes between the upper module 1 and the lower module 2, and is then received by the receiving shaft. The lower material passes through the cavity 24 on the bottom surface of the concave mold plate 23, wherein the shape and size of the cavity 24 can be designed according to the type and size of the lower material.

[0022] Preferably, in order to facilitate the entry and exit of the lower material, slopes 27 may be provided at both ends of the cavity 24 .

[0023] A row of punches 14 are installed at the bottom of the upper die base 11, each punch 14 penetrates the upper frame plate 12 and the upper stripper plate 13, and a row of punch holes 26 are provided on the lower die block 2, each punch hole 26 penetrates the concave die plate 23 and is respectively located directly below each punch 14. The punches 14 and the punch holes 26 can be used to punch the upper material and the lower material.

[0024] Two rows of guide posts 15 are installed at the bottom of the upper die base 11, and each guide post 15 passes through the upper frame plate 12 and the upper stripper plate 13, and two rows of avoidance holes 25 are vertically arranged on the lower die block 2, and each avoidance hole 25 passes through the lower frame plate 22 and the concave die plate 23 and is respectively located directly below each guide post 15. The guide posts 15 and avoidance holes 25 are provided to guide the punching work of the upper die block 1 and the lower die block 2. Among them, each avoidance hole 25 is distributed on both sides of the outside of the die cavity 24, and is staggered from the die cavity 24, so that when only the upper material needs to be punched, the lower material passing through the bottom will not be punched.

[0025] In addition, two rows of positioning columns 16 are installed at the bottom of the upper die base 11, and two rows of positioning holes 28 are provided on the lower die block 2, each positioning hole 28 passes through the concave die plate 23 and is respectively located directly below each positioning column 16. The positioning columns 16 and the positioning columns 16 can be used to further position the punching of the upper material and the lower material.

[0026] The double-feeding rapid mold in the utility model mainly has the following beneficial effects:

[0027] 1. When punching the upper material, the lower material that passes through the bottom will not be punched;

[0028] 2. The material can be changed for punching according to the demand;

[0029] 3. It can realize the simultaneous punching of different materials, and also the asynchronous punching of upper and lower materials;

[0030] 4. Reduce the pasting time, improve production efficiency and product quality.

[0031] 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.
