Processing equipment adapting to thickness change and used for automobile special-shaped plastic covering part processing

Abstract

The invention discloses processing equipment adapting to thickness change and used for automobile special-shaped plastic covering part processing, and relates to the technical field of automobile plastic covering part injection molding processing. The equipment particularly comprises a cooling pool, an injection mold mechanism, a heat transmission extrusion mechanism and a disc type continuous drying mechanism, a conveying belt is arranged at the middle end of the cooling pool, a through groove is formed in the surface of a piston injection molding mechanism, a piston is arranged in a piston cavity, the disc type continuous drying mechanism is arranged on one side of the surface of a shell, a bin body is arranged on the surface of the disc type continuous drying mechanism, material bafflesare fixed to the periphery of a second drying disc, and a discharging port is formed in the bottom of the bin body. According to the equipment, by arranging the cooling pool, workpieces, the appearance of which is required to have no sink marks but the interiors of which are allowed to have shrinkage holes, can be quickly soaked in frozen water after mold stripping, so that the workpieces are cured and cooled in a short time, and the sink marks are prevented from being generated; and this method is relatively effective for products with relatively large wall thicknesses.

Description

technical field [0001] The invention relates to the technical field of injection molding processing of automobile plastic cover parts, in particular to a processing equipment adapted to thickness changes for processing special-shaped plastic cover parts of automobiles. Background technique [0002] The key link of injection molding processing is to make various forms of plastics (powder, pellets, solutions or dispersions) into products or blanks of the desired shape. There are more than 30 molding methods, and its choice is mainly determined by The type of plastic (thermoplastic or thermosetting), the initial form, and the shape and size of the product. Common methods for processing thermoplastics include extrusion, injection molding, calendering, blow molding, and thermoforming. Plastic, injection molding is also used. Lamination, molding and thermoforming are used to shape plastics on a plane. In addition, there are castings using liquid monomers or polymers as raw materia...

AI Technical Summary

Problems solved by technology

The common problems of the existing injection molding processing equipment for plastic panels of automobiles are: plastic processing shrinkage is one of the most common problems in plastic processing, and shrinkage is even more difficult for plastic products that require high surface quality. The cooling rate of the thick area is much slower than that of the surrounding area, and the difference in cooling rate leads to the formation of depressions and shrinkage marks at the joint surface
