[0030] Specifically, as Figure 1 shown, during processing, the material is added into the heating box 2 through the feeding port 7. After heating, the material guiding valve pipe 10 is opened to inject the molten material into the moving mold 11. After the workpiece is formed, the hydraulic cylinder 6 is started to drive the lifting plate 3 to rise. The lifting plate 3 drives the moving mold 11 at the bottom to rise through the heating box 2 and the material guiding valve pipe 10, so as to quickly open the mold for convenient discharging. And the limiting sleeve barrels 8 and the limiting sleeve plates 12 are attached to the outside of the column 4 to limit the moving mold 11, ensuring that the moving mold 11 rises vertically to improve the mold closing accuracy, realizing automatic opening and closing of the mold.

[0031] Embodiment 2: An installation cavity 16 is arranged on one side inside the bottom box 1. A water pump 15 is fixedly connected to the bottom end inside the installation cavity 16. The output end of the water pump 15 is fixedly connected to a water injection pipe 14. The input end of the water pump 15 is fixedly connected to a water suction pipe 17.

After heating, the guiding valve pipe 10 is opened to inject the molten material into the moving mold 11. When the material is fed into the moving mold 11 and the forming groove 20, the water pump 15 can be started to draw out the cooling water in the bottom box 1 through the water suction pipe 17, and then the water is introduced into the inside of the fixed mold base 18 through the water injection pipe 14 and the water inlet 13. After the cooling water flows into the fixed mold base 18 and adheres to the bottom end of the forming groove 20, it can quickly exchange heat with the material inside the forming groove 20, thereby accelerating the cooling rate of the workpiece inside the forming groove 20. After the workpiece is formed, the hydraulic cylinder 6 is started to drive the lifting plate 3 to rise. The lifting plate 3 drives the moving mold 11 at the bottom to rise through the heating box 2 and the guiding valve pipe 10, so as to quickly open the mold for convenient discharging.

After demolding is completed, the positioning plate 19 is reset and attached to the inside of the groove 23. The gasket 24 inside the groove 23 is attached to the bottom end of the positioning plate 19 to prevent water seepage.
