An embedding groove is opened on the rear surface of the die body, a circle of limit grooves is opened on the groove wall of the embedding groove, and a plurality of forming holes are opened at the bottom of the limit groove; the mesh body is embedded in the embedding groove, the C-shaped steel bar is embedded in the embedding groove, and the C-shaped steel bar is elastically pressed on the bottom of the limit groove or the edge of the outer groove of the limit groove, and the C-shaped steel bar is tightly pressed on the outer surface of the mesh body; the limit block is arranged in the embedding groove, and the limit block is pressed on the outer surface of the mesh body, and the two ends of the limit block are respectively pressed on the end faces of the two ends of the C-shaped steel bar; the screw passes through the limit block and the mesh body in turn and is screwed to the bottom of the embedding groove. The utility model has the advantages of simple structure, high reliability, convenient maintenance, etc., and can effectively improve the extrusion quality of related products.

[0004] The above-mentioned patent embodiment records that "because the mesh body is embedded in the embedding groove, the mesh body can be located on the inner side of each forming hole, so that the molten plastic must be filtered by the mesh body before entering the forming hole, which can filter out impurities and unmelted granular raw materials through the mesh body, thereby avoiding them from being mixed in the molded product, and thus helping to improve the quality of the product."

[0024] The outside of the two pulling components are both sleeved with springs 5, and the pulling components include pulling plates 4. The proximal sides of the two pulling plates 4 are respectively fixedly connected to the distal sides of the two limit plates 3, so that when the pulling plates 4 move, the limit plates 3 will be driven to move. The distal sides of the two pulling plates 4 respectively penetrate the distal inner walls of the two cavities 2 and extend outward. The proximal sides of the two pulling plates 4 are respectively slidably connected to the inside of the two cavities 2, so that the movement of the pulling plates 4 can be more stable. The proximal sides of the two limit plates 3 are fixedly connected with a locking plate 6.

[0025] Furthermore, when the limit plate 3 moves, the locking plate 6 will be driven to move. A filter plate 7 is provided inside the discharge pipe 1. Locking grooves 8 are provided in the middle of the left and right sides of the filter plate 7. The adjacent sides of the two locking plates 6 respectively penetrate the adjacent inner walls of the two cavities 2 and extend outward. The adjacent sides of the two locking plates 6 are respectively locked with the inside of the two locking grooves 8, so that the filter plate 7 is fixed to the inside of the discharge pipe 1 through the internal locking of the locking plate 6 and the locking groove 8. The rear side of the discharge pipe 1 is threadedly connected with a feeding pipe 9, so that the material entering the feeding pipe 9 can enter the inside of the discharge pipe 1, and the rear side of the feeding pipe 9 is fixedly connected with a supporting plate 10.

[0026] A motor 11 is fixedly connected to the top of the supporting plate 10, so that the supporting plate 10 can provide support for the motor 11, and the output end of the motor 11 is fixedly connected to the auger conveyor 12. Then starting the motor 11 can make the output end of the motor 11 drive the auger conveyor 12 to rotate, so that the auger conveyor 12 can convey the material entering the feeding pipe 9 when rotating. The rear side of the auger conveyor 12 penetrates the rear inner wall of the feeding pipe 9 and extends outward, and the top of the feeding pipe 9 is fixedly connected to the feeding pipe 13.
