[0023] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] Figure 1-Figure 3 As one embodiment of the utility model, a hot pressing punching and forming mold includes a mounting base frame 1, a module 2 for hot pressing raw materials is mounted in the mounting base frame 1, and a traction component 3 is arranged opposite to the module 2 to establish a separation state of the guiding module 2.

[0026] The specific problem addressed by this specific embodiment is that it solves the problem that the waste from punching the product sticks to the mold, making it difficult to demold the product and affecting continuous production. The utility model utilizes the upper mold insert 23 and the lower mold insert 24 installed between the upper mold core 21 and the lower mold core 22 for punching the raw material, which can achieve the punching of the raw material and the removal of the waste, and the waste channel 244 opened on the lower mold insert 24 separates the waste, the raw material and the mold, and maintains the position of the punch block 232 in the raw material to facilitate the maintenance of the punching shape.

[0027] In this specific embodiment, the traction assembly 3 includes a load-bearing frame 31 and a lifting and synchronous frame 32 connected by a cylinder. The mold group 2 includes an upper mold core 21 and a lower mold core 22. The load-bearing frame 31 is installed on the installation reference frame 1 and is symmetrically connected to both sides of the lower mold core 22. Relatively, the upper mold core 21 is installed between two symmetrical lifting and synchronous frames 32 and is synchronously driven by the lifting and synchronous frames 32. The lifting and synchronous frames 32 are connected to a top frame 6, which is rigidly connected to the upper mold core 21 by bolts, thereby indirectly forming a connection state between the lifting and synchronous frames 32 and the upper mold core 21. An inner sinking groove is provided on the lower mold core 22 for filling raw materials. When in use, the overall structure is in a static state, that is, the cylinder between the load-bearing block and the lifting block is in a contracted state, and the upper mold core 21 and the lower mold core 22 are in a docking state. When in use, the static state is first released, and the controller controls the cylinder to extend, that is, the top frame 6 is pushed up by the lifting synchronization frame 32 and rises, and synchronously drives the upper mold core 21 connected to the top frame 6, thereby exposing the raw material loading position.

[0028] In this specific embodiment, an upper die insert 23 and a lower die insert 24 are embedded between the upper die core 21 and the lower die core 22 for punching the raw material. The upper die insert 23 includes an upper die fixing rod 231 connected to the upper die core 21. The upper die fixing rod 231 is a screw in this embodiment, which is threadedly connected to the upper die core 21. In this embodiment, both the upper die core 21 and the lower die core 22 are provided with an inner cavity. The lower end of the lower die insert 24 is provided with two left-right symmetrical lower die fixing screw rods connected to the lower die core 22. A positioning block and a punch block 232 connected to the positioning block are installed at its lower end. The punch block 232 extends downward. The length is greater than the structural length of the positioning block itself, and the lower mold insert 24 includes a docking block 242 installed in the inner sink groove and provided with a punching cutout 241. The docking block 242 is formed with a docking port 243 that is adapted to the position and size of the punching block 232. The lower end of the docking port 243 is connected to a waste channel 244 opened on the structure of the lower mold core 22. The opening length of the waste channel 244 passes through the lower mold core 22 and extends toward the mounting reference frame 1. The lower mold core 22 and the mounting reference frame 1 are spaced apart by a plurality of support columns 4. The plurality of support columns 4 are divided into a plurality of inner cavities at the spacing, and a drawer 5 is slidably installed in a single inner cavity. First, the upper die insert 23 and the lower die insert 24 are placed in the upper die core 21 and the lower die core 22, wherein the upper die insert 23 is fixed to the upper die core 21 by the threaded connection of the upper die fixing rod 231, and the lower die insert 24 is connected to the lower die core 22 by screwing the lower die fixing screw. Then, the raw material is heated and placed in the inner sink. After the punch block 232 contacts the raw material and cuts the raw material, it continues to press down, that is, the cylinder gradually retracts, and the punch block 232 gradually passes through the raw material and docks into the inner interface. The fragments at the punching place of the raw material will be cut by the punch block 232 and the shear of the lower die insert 24. As a result, the waste will fall into the drawer 5 under the push of the punch block 232, and will be cleaned after accumulating to a certain amount. The punched surface of the raw material will form a smooth surface facing the heating of the mold. As a result, the punched product can be obtained when the upper die core 21 and the lower die core 22 are separated again.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
