Plastic uptake forming method, plastic uptake forming machine and auxiliary devices

Abstract

The invention discloses a plastic uptake forming method, a plastic uptake forming machine and auxiliary devices, and belongs to the field of plastic uptake formation. The plastic uptake forming machine comprises a plastic uptake forming machine body, and multiple plastic uptake forming machine auxiliary devices distributed around the plastic uptake forming machine for pushing the edge parts of products covered on the plastic uptake forming machine body to an appointed position. The plastic uptake forming machine auxiliary devices comprise pressure parts for contacting with the edge parts of the products, extension parts connected with the pressure parts and extending to move the pressure parts, and power parts for providing power for extension of the extension parts. The plastic uptake forming machine overcomes such quality defects as easy wrinkling on the outer surfaces of the manufactured products, acute texture change, thinning by stretching or damage by stretching when a traditional plastic uptake forming process is adopted to manufacture the products with higher high-low falls on structures.

Description

technical field [0001] The invention relates to the field of blister forming, and more specifically, to a blister forming method, a blister forming machine and an auxiliary device thereof. Background technique [0002] Plastic molding is the process of making plastics in various forms (powder, pellets, solutions and dispersions) into products or accessories of the desired shape. Plastic molding methods include injection molding, extrusion molding, compression molding, blow molding, casting molding, and blister molding. Blister forming, also known as vacuum forming, is one of the thermoplastic thermoforming methods. The method of blister forming is to use a blister forming machine to clamp the sheet or plate material on the frame of the vacuum forming machine. After heating and softening, it will be absorbed on the mold by vacuum through the air channel on the edge of the mold. After a period of cooling, molded plastic products are obtained. Automotive interior parts gener...
