Description

Technical Field

[0001] The utility model relates to the technical field of plastic shell processing, in particular to a plastic shell molding device. Background Art

[0002] Plastic shell is a kind of shell made of plastic as the main raw material. Plastic is a high molecular compound polymerized by addition polymerization or condensation polymerization with monomer as raw material. Its deformation resistance is medium, between fiber and rubber. It is composed of synthetic resin and fillers, plasticizers, stabilizers, lubricants, colorants and other additives.

[0003] After searching, the Chinese patent with application number 202021086336.1 discloses a molding device for processing plastic shells, including a box body, a rocker, an extrusion plate, an electric lifting rod and a door panel. Both ends of the bottom end of the box body are installed with slide rails, and a slider is arranged inside the slide rail. A support plate is installed at the end of the slider away from the slide rail, and a fixing plate is evenly installed at the top of the support plate. An electric lifting rod is installed at the top of the box body, and a U-shaped plate is installed at the bottom end of the electric lifting rod. A first groove is opened at the bottom end of the U-shaped plate, and both ends of the first groove are opened inside. A mounting block is arranged inside the first groove, and a fixing rod is evenly installed at the bottom end of the box body. The limiting block of the molding device for processing plastic shells is detached from the inside of the limiting hole, which makes it easy for the mounting block to detach from the inside of the first groove, so that the operator can disassemble and install it, reducing the labor intensity of the operator. Most of the plastic shells are injection molded by injection molding devices during processing. The following defects or deficiencies exist in the processing of plastic shells:
