A hydraulic rod 5 pushes the pressure plate 14 to extrude and form the sheet. When production is complete or when changing molds 15, the ejector plate 11 ejects the mold 15, and the new mold is placed on the worktable and fixed, facilitating easier mold disassembly.

[0036] When using the molding equipment for high molecular weight polyethylene sheets, water is first injected into the water tank 10 through the funnel 12. Excess water overflows from the outlet pipe 22. Then, the copper pipe 23 is cooled by the heat sink 9, which cools the water in the water tank 10. Then, the fan 8 is turned on to promote the heat dissipation effect of the heat sink 9. The water pump 18 draws water out of the water tank 10 through the water pipe 17 at the input end. Then, the water is injected into the water pipe 17 through the output end of the water pump 18 so that the cooling water cools the pressure plate 14, achieving the cooling effect in the process of making high molecular weight polyethylene sheets.
