[0062] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0063] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0064] Embodiment 1:

[0065] In order to solve the problems in the prior art of mobile phone four-frame glue products that waste is difficult to discharge during the production and processing, resulting in a high product defect rate and high product production cost, the present embodiment provides an automatic punching and waste discharge mold. By arranging a waste discharge mechanism on the punching and cutting mold, automatic waste removal can be achieved during the punching and cutting process, with high production efficiency and good product quality stability.

[0066] See also Figure 1 The embodiment discloses an automatic punching and waste discharge mold, comprising: a lower mold assembly 1, an upper mold assembly 2, a cutting blade 3, a waste discharge mechanism 4 and a material pushing mechanism 5.

[0067] The upper die set 2 is located above the lower die set 1 and can move in the vertical direction to approach or move away from the lower die set 1 .

[0068] The cutter member 3 is installed on the surface of the upper die set 2 opposite to the lower die set 1 , and has a square-shaped cutting edge 31 , which can punch and cut the material when the upper die set 2 is close to the lower die set 1 .

[0069] The waste discharge mechanism 4 is located between the upper die set 2 and the lower die set 1 and is connected to the upper die set 2 and the lower die set 1 respectively, and can realize horizontal movement when the upper die set 2 approaches or moves away from the lower die set 1 .

[0070] Specifically, when the upper die group 2 moves downward to approach the lower die group 1 to achieve material punching, the waste discharge mechanism 4 moves horizontally to the outside of the upper die group 2 and the lower die group 1. After completing the punching of the material, when the upper die group 2 moves upward to move away from the lower die group 1, the waste discharge mechanism 4 moves horizontally to below the blade 31 of the cutting blade 3.

[0071] The pushing mechanism 5 is arranged in the upper mold assembly 2 and is located above the cutting blade 3. The pushing mechanism 5 abuts against the waste discharge mechanism 4 and can move in the vertical direction during the horizontal movement of the waste discharge mechanism 4 to push the waste located in the blade 31 out into the waste discharge mechanism 4.

[0072] Specifically, when the waste discharge mechanism 4 moves horizontally to below the blade 31 of the cutting blade 3, the pushing mechanism 5 is forced to move downward to push the waste located in the blade 31 out into the waste discharge mechanism 4; when the waste discharge mechanism 4 moves horizontally to the outside of the upper die set 2 and the lower die set 1, the pushing mechanism 5 moves upward.

[0073] Therefore, the automatic punching and waste discharge mold disclosed in this embodiment is provided with a waste discharge mechanism 4 which is respectively connected to the upper die group 2 and the lower die group 1, and is capable of realizing horizontal movement when the upper die group 2 approaches or moves away from the lower die group 1. The control process of the waste discharge mechanism 4 adopts a mechanical principle. At the same time, the pushing mechanism 5 also moves up and down during the movement of the waste discharge mechanism 4, thereby pushing the waste and pushing it to the waste discharge mechanism 4 for discharge. The pushing mechanism 5 cooperates with the waste discharge mechanism 4 to realize the automatic discharge of the waste, which improves the product production efficiency while also improving the product quality.

[0074] In some optional embodiments, since the punching and waste removal mold disclosed in this embodiment is used to produce four-frame glue for mobile phones, Figure 2 As shown, the cutting blade 3 includes a square-shaped blade 32, and the blade edge 31 is the space surrounded by the blade 32. A blade groove 33 is provided between the blade 32 and the blade edge 31. It can also be understood that the blade groove 33 is provided along the blade 32 on the side of the blade 32 close to the blade edge 31. The cutting blade 3 implements punching of the material when the upper die set 2 is close to the lower die set 1, and the waste material after punching occupies the blade groove 33 and the blade edge 31.

[0075] In addition, in this embodiment, the punching and waste discharge mold also includes a plurality of sharp needles 61, which are installed on the opposite surface of the upper mold group 2 to the lower mold group 1. A needle hole 62 matching the sharp needles 61 is provided on the upper mold group 2. The sharp needles 61 pass through the blade 31 and can position the material when the cutting blade 3 punches the material, and cooperate with the knife groove 33 to limit and fix the waste after the material is punched.

[0076] Specifically, Figure 3 As shown, the end of the sharp needle 61 extends outwardly along the radial direction of the sharp needle 61 to form a locking portion 611. When the upper die set 2 moves downward, the sharp needle 61 penetrates the material and is embedded in the needle hole 62 to fix the material. When the cutter 3 completes punching the material, the waste material after punching is located above the locking portion 611 of the sharp needle 61, and cooperates with the knife groove 33 to stabilize the waste material at the knife edge 31, and moves upward synchronously with the upper die set 2. Then, with the cooperation of the waste discharge mechanism 4 and the material pushing mechanism 5, the waste material is pushed out from the knife edge 31 into the waste discharge mechanism 4.

[0077] In some optional embodiments, the waste discharge mechanism 4 includes a guide frame 41 and a waste discharge hopper 42 fixedly connected to the guide frame 41; a first sliding portion 43 is provided at the upper end of the guide frame 41, a second sliding portion 44 is provided at the lower end of the guide frame 41, a third sliding portion 211 is provided on the upper mold group 2 and slidingly cooperates with the first sliding portion 43, and a fourth sliding portion 13 is provided on the lower mold group 1 and slidingly cooperates with the second sliding portion 44.

The side wall of the mounting seat 54 away from the ejector pin 51 abuts against the connecting plate 413 of the waste discharge mechanism 4. The mounting seat 54 forces the pushing block 52 to move along the first guide groove 511 during the horizontal movement of the waste discharge mechanism 4, so as to force the ejector pin 51 to move in the vertical direction.

[0084] This embodiment is a preferred embodiment. The first guide groove 511 is inclined. The push block 52 includes a horizontal block 521 connected to the mounting seat 54 and an inclined block 522 that can be embedded in the first guide groove 511.

[0085] After punching is completed, the upper die set 2 moves upward and away from the lower die set 1, and the waste discharge mechanism 4 moves horizontally to below the blade 31 of the cutting member 3. At the same time, the mounting seat 54 is forced to compress the elastic member 53 and move horizontally toward the ejector pin 51, so that the push block 52 extends into the first guide groove 511. In this process, the ejector pin 51 is forced to move downward to eject the waste fixed in the blade 31 into the waste discharge hopper 42 of the waste discharge mechanism 4.
