Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5This utility model provides a technical solution: a simplified core-pulling structure for injection molds, including an upper mold 1, a lower mold 2, a pneumatic cylinder 3, a drive rod 4, a closed template 5, a core 6, a mold core 7, a first bolt rod 8, a sealing groove 9, a sealing buckle 10, a splicing slot 11, a positioning block 12, a positioning slot 13, a limiting groove 14, a second bolt rod 15, a connecting slot 16, a limiting slider 17, a transmission telescopic rod 18, and a closed cover plate 19. The lower mold 2 is installed at the lower end of the upper mold 1, and the mold core 7 is installed at the middle position of the upper end of the lower mold 2. A splicing slot 11 is opened on one side of the upper mold 1, and a sealing groove 9 is opened on one edge of the inner wall of the splicing slot 11. A closed template is inserted and installed on the inner wall of the splicing slot 11. 5. A sealing buckle 10 is fixedly connected to one edge of the outer wall of the closed template 5. The closed template 5 is installed in a sealed manner by inserting the sealing groove 9, the sealing buckle 10 and the splicing slot 11. The sealing buckle 10 is fixedly installed to the sealing groove 9 by the first bolt rod 8. This makes it easy to position, seal and disassemble the closed template 5 for easy replacement. The sealing buckle 10 is inserted into the sealing groove 9, and the first bolt rod 8 is inserted through the inner wall of the sealing groove 9 and the sealing buckle 10. The insert 6 is movably inserted into the inner wall of the closed template 5, and one end of the insert 6 is fixedly connected to the limiting slider 17. The insert 6 is connected to the closed template 5 in a limited telescopic connection within the limiting groove 14 by the limiting slider 17. This allows the insert 6 to be limited. To prevent incomplete or excessive suction and improve performance, a limiting slider 17 is fitted with a limiting groove 14 on its outer wall. One end of the limiting groove 14 is fixedly connected to the outer wall of the closed template 5. A transmission telescopic rod 18 is vertically fixedly connected to the middle of the other end of the limiting slider 17. A connecting slot 16 is provided on the inner wall of the other end of the transmission telescopic rod 18. A closing cover 19 is installed at the other end of the limiting groove 14. A positioning block 12 is fixedly connected to the protruding edge of the other end of the closing cover 19. A pneumatic cylinder 3 is fitted to the other end of the closing cover 19. The pneumatic cylinder 3 is installed in a positioning splicing manner with the limiting groove 14 through the positioning block 12 and the positioning slot 13. This makes it easy to position and splice the pneumatic cylinder 3 for easy fixed use. 3. The drive rod 4 is installed in the connecting slot 16 and the transmission telescopic rod 18 in an interlocking manner. The drive rod 4 is fixed to the connecting slot 16 by the second bolt rod 15. This allows the pneumatic cylinder 3 to easily drive the drive rod 4 for stable operation. The closed cover plate 19 is screwed to the limiting groove 14 for easy opening and closing. This allows the limiting groove 14 to be easily opened for cleaning and disassembly and assembly of the insert 6. The pneumatic cylinder 3 has a positioning slot 13 on one edge. The positioning block 12 is installed in the positioning slot 13. The output end of the pneumatic cylinder 3 is fixedly connected to the drive rod 4, and the drive rod 4 is installed in the connecting slot 16. The connecting slot 16 and the drive rod 4 are installed in the side by the second bolt rod 15.

[0020] Working principle: When using this simplified male mold core-pulling structure for injection molds, the device is first assembled and installed, and then injection molding is performed. When demolding is required, the pneumatic cylinder 3 can drive the core 6 to retract, and the limiting groove 14 and limiting slider 17 provide limiting support, so that one end of the core 6 is flush with the inner side of the closed template 5. Then demolding is performed. When the pneumatic cylinder 3 is damaged, it can be disassembled and installed independently through the positioning block 12, positioning slot 13 and the second bolt rod 15. When it is necessary to replace a different core 6, the closed template 5 can be removed through the first bolt rod 8, sealing groove 9 and sealing buckle 10. Then the closed template 5, core 6, limiting groove 14 and limiting slider 17 can be removed and replaced. When the inner wall of the limiting groove 14 needs to be cleaned or lubricated, the closing cover plate 19 can be screwed open for cleaning. This is the usage process of this simplified male mold core-pulling structure for injection molds.
