[0034] Working principle:

[0035] First, the injection port inside 5 is connected to the injection head on the external injection molding machine, and then the oil cylinder 8 is driven so that the output shaft of the oil cylinder 8 drives the connected top plate 11 to move upward, and then the two male molds 7 on the top plate 11 are overlapped with the male mold groove 14 inside the female mold 6. During the overlapping process, the limit block inside the male mold groove 14 is overlapped with one end of the ejection hole on the male mold 7 to prevent the injection melt from overflowing from the ejection hole inside the male mold 7. When the injection molding machine injects the plastic melt into the injection port, the plastic melt reaches the outside of the male mold 7 through the injection groove. When the injection melt on the male mold 7 is formed, the output shaft of the oil cylinder 8 drives the top plate 11 to slowly move upward. The mold 7 is pulled down, and the ejector pin 10 on the bottom plate 16 passes through the ejection hole during the pulling process, thereby loosening the plastic product on the male mold 7, so that the product can be taken out. When the male mold 7 needs to be maintained, the motor 15 can be driven to make the output shaft of the motor 15 drive the screw 17 to rotate, and then the rotation of the screw 17 drives the sleeved movable seat 18 to move, and then the bottom plate 16 fixedly connected to the movable seat 18 is moved, so that the bottom plate 16 slides on the slide groove 12 along the slider 13 at the bottom, and then the male mold 7 is moved to one side of the support plate 1, so that it can be maintained, reducing the labor intensity of workers carrying the mold.
