Problems solved by technology

Among them, the gypsum mold has low cost and simple preparation process, but the service life and the surface quality of the finished product are low; while the electrolytic copper mold and the alloy aluminum mold can make the finished product have a good surface quality, and the service life is relatively long, but the cost of the two It is higher than the plaster mold, and the preparation process is complicated and the preparation cycle is long

Abstract

The invention discloses a preparation method of a gypsum plastic suction mold. The preparation method comprises a, work mold preparation, b, reinforcement treatment, c, polishing treatment, and d, mold aftertreatment. The preparation method has reasonable processes, can be implemented simply, and has a moderate preparation cost. The gypsum plastic suction mold has a reinforced layer structure on the surface. The reinforced layer structure has the advantages of reasonable cost and stable and excellent film forming ability and can effectively improve strength, surface quality and a service life of the gypsum mold and improve practicality of the gypsum plastic suction mold.

Description

technical field [0001] The invention relates to a preparation method of a plaster blister mold, in particular to a preparation method of a gypsum blister mold with excellent surface quality and service life and moderate cost, and belongs to the technical field of plastic blister forming machine accessories. Background technique [0002] Blister molding machine is also called thermoplastic molding machine. Its working principle is: use the vacuum suction generated by the vacuum pump to heat and soften thermoplastic plastic sheets such as PVC, PET, PETG, APTT, PP, PE, PS, etc., through the mold suction. It can be molded into vacuum covers of various shapes, or attached to the surface of products of various shapes. The blister process can be divided into thin sheet blister and thick sheet blister according to the thickness of the sheet. [0003] The mold used on the blister forming machine is called a blister mold, which heats a flat plastic sheet to soften it, then absorbs it...
