Abstract

The invention discloses spraying-free plastic, a forming device for production and a forming method, and relates to the technical field of plastic forming. The demolding problem is solved. The spraying-free plastic comprises ABS resin and 15-20 parts of AS resin, the forming device comprises a base, the top of the base is connected with a supporting seat through a supporting column, an automatic demolding type forming mechanism is arranged at the top of the supporting seat, and the automatic demolding type forming mechanism comprises two sets of opposite half mold assemblies. The forming method comprises the steps that a hydraulic cylinder is started, two half mold bodies are attached to each other to form a closed cavity, then mixed and molten raw materials are injected into the closed cavity of the two half mold bodies, forming can be achieved after the raw materials are cooled, the hydraulic cylinder is controlled to contract at the moment, and automatic demolding of a finished product and the two half mold bodies can be completed. According to the spraying-free plastic, the forming device for production and the forming method, in the whole forming process, demolding of the finished product and the two half mold bodies can be achieved, demolding is carried out automatically and is synchronous with mold closing and mold splitting, and the demolding is reliable and convenient to use.

Description

technical field [0001] The invention relates to the technical field of plastic molding, in particular to a spray-free plastic, a molding device for production and a molding method. Background technique [0002] Spray-free plastics have been widely used due to their advantages of saving process steps. The preparation process of spray-free plastics is similar to that of ordinary plastics. They are basically formed by injection molding. After the raw materials are fully mixed, heated and melted, they are sealed It can be cooled and formed in the mold. [0003] After retrieval, the Chinese Patent Publication No. is CN211334250U, which discloses an intelligent plastic floor production hot press forming device, including a support seat, a support rod, a connecting and fixing rod, a top plate, an electric push rod, and a heatable stamping seat structure. The structure of the heating placement seat can observe the structure of the preheating box, the infrared temperature sensor, th...
