Description

Technical Field

[0001] The utility model relates to a cooling device for a plastic sheet material mold, belonging to the technical field of plastic sheet material production equipment. Background Art

[0002] In the production process of plastic sheet materials, the plastic is first heated to a molten state, and then various additives such as stabilizers, pigments, and reinforcing materials are added. The mixture is then fed into a mold for extrusion and pressing to form the desired sheet shape. After searching, it was found that the Chinese patent with the publication number CN220052809U discloses a wear-resistant plastic sheet extrusion molding die. In this patent, the motor is turned on, and the motor drives the driving sprocket to rotate through the transmission chain. The rotation of the driving sprocket is transmitted to the driven sprocket, which in turn drives the bidirectional screw to rotate. The rotation of the bidirectional screw drives the nut to move along the screw axis. The movement of the nut is transmitted to the power plate through the side connecting column, causing it to move relative or toward each other along the guide groove to adjust the molding size of the plastic sheet, so that the thickness of the plastic sheet can be adjusted during the extrusion process. However, in this patent, when the molten plastic mixture enters the mold, a large amount of heat is transferred to the mold. If the mold is not cooled in time, substandard products will be produced, increasing production costs. Summary of the Invention
