Automatic demoulding device of bevel-connection special-shape bottle of plastic injection and blow molding machine

Abstract

The invention discloses an automatic demoulding device of a bevel-connection special-shape bottle of a plastic injection and blow molding machine. The automatic demoulding device comprises a workbench, wherein the workbench is provided with a turret; the turret is provided with a mandril; the mandril is matched with the inner wall of the bottle neck of the bevel-connection special-shape bottle; the workbench is provided with a demoulding rack; the demoulding rack is provided with a demoulding plate; the demoulding plate is matched with the neck of the bevel-connection special-shape bottle; anoverturning oil cylinder is installed below the demoulding rack; the piston rod of the overturning oil cylinder is connected with an overturning connecting rod; and the overturning connecting rod drives the demoulding plate to rotate. The automatic demoulding device is characterized in that the side wall of a workbench is provided with a fixed support; the fixed support is provided with a linear guide rail; the demoulding rack is installed on the linear guide rail; the linear guide rail is connected with a demoulding oil cylinder; the fixed support is provided with a guide rail; a guide rod is installed below the demoulding rack; and the guide rod is matched with the guide rail. The scheme has the advantages of stable and reliable demoulding action and wide applicable range.

Description

technical field [0001] The invention relates to an automatic stripping device for special-shaped bottles with oblique openings of a plastic injection blow molding machine, which belongs to the field of plastic machinery. Background technique [0002] Using plastic (mainly referring to PE, PP, PC) as raw material, it is processed into hollow containers (plastic bottles) by injection blowing, such as medicine bottles, cosmetic bottles and food bottles, etc., and can be applied to a one-step automatic plastic injection blow molding machine The machine has two parts: injection molding and blow molding, and the injection blow mold is installed on the same worktable, which is divided into three stations: injection molding, blow molding and demoulding. A triangular turret is installed on the workbench. Mandrels are installed on the three sides respectively, and the mandrels cooperate with the injection mold to make the plastic injection molded into preforms. The preforms are rotate...

AI Technical Summary

Problems solved by technology

The demoulding oil cylinder described in the prior art is fixed on the side wall of the workbench by the fixing plate, and the demoulding oil cylinder is connected with the stripping plate, and both the demoulding oil cylinder and the stripping plate cannot be moved, but if the plastic bottle to be blown is a special-shaped bottle, according to The shape of the special-shaped bottle needs to adjust the position of the stripping plate at all times so that the stripping plate can match the neck of the special-shaped bottle. Therefore, the demoulding device in the prior art cannot achieve the purpose of stripping the special-shaped bottle
