[0026] Reference Figure 1-5This utility model discloses a hot runner insert mold, comprising: a mold plate 1, with disassembly heads 3 movably connected to the four corner edges of the mold plate 1. The disassembly heads 3 facilitate the disassembly and replacement of insert pins 7. Insert pins 7 are fixedly connected to the bottom end of the disassembly head 3. Locking grooves 8 are provided on both sides of the circumferential surface of the disassembly head 3. A pin block 19 is inserted into one side of the locking groove 8. After the pin block 19 disengages from the locking groove 8, the protective sleeve 16 at the corresponding end of the disassembly head 3 is threaded off. A connecting block 12 is inserted into the other side of the locking groove 8. The connecting block 12 engages with the disassembly head 3 to achieve locking and fastening. A connecting rod 13 is fixedly connected to the end of the connecting block 12 away from the insert pin 7. A buffer spring 14 is sleeved on the outside of the connecting rod 13. The buffer spring 14 increases the elastic support of the connecting rod 13 to one end. The other end of the buffer spring 14 is fixedly connected to the inner wall of the mold plate 1. The top center of the mold plate 1 is fixedly connected to the injection tube 2. By covering the two mold plates, the liquid is injected through the injection tube 2 at the top. The bottom end of the injection tube 2 is fixedly connected to the insert pin 7. The liquid flows through the branch tube 17 to the inside of the insert pin 7 to complete the injection molding of the mold. Rubber layers 15 are provided on both sides between the disassembly head 3 and the mold plate 1. The end of the connecting rod 13 away from the plug block 12 is fixedly connected to the pull rod 5.
