Container liner plastics suction mold for refrigerator production

Abstract

The invention discloses a container liner plastics suction mold for refrigerator production. The container liner plastics suction mold comprises a material bearing plate. Brackets are fixedly arrangedat the corner positions of the outer surface of the lower end of the material bearing plate. Hydraulic tanks are movably arranged at the inner corner positions of the material bearing plate. A mold main body is fixedly arranged at the middle position of the outer surface of the upper end of the material bearing plate. Hydraulic rods are movably arranged at the corner positions of the outer surface of the upper end of the material bearing plate. A material pressing frame is fixedly arranged at the upper ends of the hydraulic rods. A sealing cavity is formed in the material pressing frame. Plates are movably arranged on the inner surface of the periphery of the material pressing frame. An air inlet hole is formed in one side of the outer surface of the front end of the pressing frame. According to the container liner plastics suction mold, a series of structures are arranged to enable the device to realize mold forming in the using process by a vacuumizing mode and a pressure emptying mode, so that the forming effect of a plastics suction liner is better, the forming time is shorter, the efficiency is higher, the yield is higher, and the using process is optimized.

Description

technical field [0001] The invention relates to the technical field of plastic-absorbing molds, in particular to a plastic-absorbing mold for tanks used in the production of refrigerators. Background technique [0002] The tank of the refrigerator is made of a plastic mold. The plastic mold for the tank is made of a thermoplastic sheet. After it is softened by heating, it is stretched evenly under the action of an external force. Movement, to make the sheet undergo secondary stretching, and to form a vacuum by extracting the air between the sheet and the surface of the mold, so that the sheet is completely adsorbed on the surface of the mold, and then cooled, shaped, and demoulded to become a mold for the desired part , but the existing box tank plastic mold of the refrigerator has a simple structure, and the molding effect of the plastic tube is poor, the molding time is long, the efficiency is low, the yield rate is low, and the performance of the device is reduced.
