[0031] In the utility model, the working principle of the device is as follows:

[0032] The hot raw material is added from the runner 5 into the molding cavity between the lower mold 2 and the upper mold 4 for pressing and molding. After the mold is molded and cooled, the upper mold 4 is separated from the lower mold 2, and the inclined rod 10 is driven to disengage from the slider 9 to release the restriction on the slider 9. Then, the driving motor 701 is started to push the roller 702 to move horizontally, so that the roller 702 pushes the inclined surface 704 on the fixed block 703. Under the limiting action of the guide rod 11, the fixed block 703 and the movable plate 602 can be pushed upward, and the slider 9 can be driven to move horizontally. The rail 603 moves upward, driving the connecting rod 604 to move upward through the sliding block 605, and finally driving the ejection plate 606 to move upward, gradually applying a supporting force to the workpiece to eject the workpiece. During the ejection process, the ejection plate 606 is subjected to force, and the sliding block 605 at the bottom thereof slides in the slide rail 603, which can play a buffering effect and avoid scratches on the workpiece. At the same time, the ejection plate 606 is a block-shaped body, which increases the contact area with the workpiece compared to the traditional ejector, making the ejection more uniform and avoiding deformation of the workpiece.
