[0024] By providing the ejection structure 4, the molded workpiece can be ejected, which is convenient for personnel to demould. By starting the driving motor 501 to push the roller 502 to move horizontally, the roller 502 pushes the inclined surface 504 on the connecting block 503. Under the limiting effect of the guide column 404, the connecting block 503 and the movable plate 402 can be pushed to move upward, and the ejector pin 403 can be driven to move upward at the same time, so that the top end of the ejector pin 403 gradually applies a supporting force to the workpiece to eject the workpiece.

[0025] See also Figure 1 to Figure 2 , the fixed plate 401 is fixedly connected to the upper surface of the base 1, the movable plate 402 is slidably connected to the fixed plate 401, the bottom end of the ejector pin 403 is fixedly connected to the upper surface of the movable plate 402, and the top end of the ejector pin 403 is located inside the lower mold 2, the bottom end of the guide column 404 is fixedly connected to the fixed plate 401, and the movable plate 402 is sleeved on the surface of the guide column 404, the bottom end of the return spring 405 is fixedly connected to the upper surface of the movable plate 402, and the top end of the return spring 405 is fixedly connected to the bottom of the lower mold 2;

[0026] By pushing the movable plate 402 to move upward, the ejector pin 403 is also driven to move upward, so that the top of the ejector pin 403 gradually applies a supporting force to the workpiece to eject the workpiece. The provision of multiple ejector pins 403 can make the ejection more uniform and avoid deformation of the workpiece.

[0027] See also Figure 1 and Figure 3 An adjusting assembly 5 is provided between the base 1 and the lower mold 2, and the adjusting assembly 5 includes a driving motor 501, a roller 502, a connecting block 503, an inclined surface 504 and an adjusting bolt 505.

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

[0032] The hot raw material is added from the runner 9 into the molding cavity between the upper mold 3 and the lower mold 2 for compression molding. During the mold closing process, the positioning is performed accurately by the positioning rod 6. After the mold is formed and cooled, the upper mold 3 is separated from the lower mold 2, and then the driving motor 501 is started to push the roller 502 to move horizontally, so that the roller 502 pushes the inclined surface 504 on the connecting block 503. Under the limiting action of the guide column 404, the connecting block 503 and the movable plate 402 can be pushed to move upward, and the ejector pin 403 is driven to move upward at the same time, so that the top of the ejector pin 403 gradually applies a supporting force to the workpiece to eject the workpiece. The provision of multiple ejector pins 403 can make the ejection more uniform and avoid deformation of the workpiece. When the ejection height of the ejector pin 403 needs to be adjusted, the horizontal position of the connecting block 503 can be moved by loosening the adjusting bolt 505, thereby adjusting the contact position between the roller 502 and the inclined surface 504 and the ejection height of the ejector pin 403.
