[0037] Working principle: When injection molding work needs to be carried out, start Motor 1 2. Motor 1 2 drives the rotating shaft 5 to rotate through a gear, and then drives the bottom plate 9 and the connected lifting seat 10 to move upward through the short rod 7 and the long rod 8. When reaching the apex, the connecting rod 16 pushes the lower annular plate 33 upward until the annular slider 34 catches the inside of the limit ring 35, compressing the shock-absorbing spring 32. The rod head 15 is tightly connected to the lower mold 28. At this time, the injection molding chamber composed of the upper mold 30, the lower mold 28, the rod head 15, and the lower annular plate 33 is kept airtight, and then injection molding work is carried out into the injection molding chamber through the injection pipe 36. After the injection molding is completed, when the part has cooled, start Motor 1 2 again to drive the lifting seat 10 to move downward. At this time, the connecting rod 16 gradually moves away from the lower annular plate 33, and the pressure spring 12 extends, pushing the pressing plate 13 to move relative to the lifting seat 10. The rod head 15 pushes the injection-molded part away from the lower mold 28. During this process, since the positioning post 11 is slidably connected inside the pressing plate 13 and the ejector rod 14 is slidably connected inside the receiving plate 17, the hollow shaft 20, the fourth gear 21, and the limit plate 22, the stability of the lifting seat 10 and the pressing plate 13 during the lifting movement can be ensured.

[0038] When the mold needs to be replaced, start Motor 2 18. Motor 2 18 drives the fourth gear 21 to rotate. The fourth gear 21 drives the hollow shaft 20 to rotate. The hollow shaft 20 drives the limit plate 22 to rotate. Through the cooperative movement of the curved chute 23 on the limit plate 22 and the slide rod 26, the two slide rods 26 drive the connected fixed seats 27 to move horizontally away from each other. At this time, the locking of the two fixed seats 27 on the lower mold 28 is released. The operator can first disassemble the rod head 15 on the ejector rod 14, then take out the lower mold 28 from the fixed seat 27, and then perform maintenance or mold replacement. After the operation is completed, connect the rod head 15 to the ejector rod 14, start Motor 2 18, and drive the two fixed seats 27 to move towards each other. When the two slide rods 26 both move to one end of the curved ring groove, the closing work is completed. At this time, the lower mold 28 is locked by the two fixed seats 27 and can move up and down with the lifting seat 10.
