A plastic bottle forming machine

Abstract

The invention discloses a plastic bottle forming machine. The plastic bottle forming machine comprises a rack, a cooling device, an injection molding device positioned on the top of the rack, two guide rails which are arranged in parallel on the rack, two lifting mechanisms which are correspondingly arranged on the two guide rails, a bracket of which two ends are correspondingly arranged on the two lifting mechanisms, and an opposite-opening die which is arranged on the bracket and positioned below the injection molding device, wherein the opposite-opening die comprises a left die body, a middle die body and a right die body; the right end of the left die body can cling to the middle die body to form a plurality of first empty forming cavities; the left end of the right die body can cling to the middle die body to form a plurality of second empty forming cavities; the middle die body is fixedly arranged on the bracket; compressing mechanisms for correspondingly releasing and compressing the left die body and the right die body are arranged at the left end of the left die body and the right end of the right die body and are positioned on the bracket. According to the plastic bottle forming machine, the plurality of first empty forming cavities and the plurality of second empty forming cavities are arranged, so that a plurality of plastic bottles can be formed and manufactured by injection molding in one time, and as a result, the production efficiency can be greatly improved.

Description

technical field [0001] The invention relates to a device for forming plastic into a plastic container, in particular to a plastic bottle forming machine. Background technique [0002] Blow molding machine is a conventional plastic processing method. It is a tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin. The compressed air is passed into the parison to inflate the plastic parison and cling to the inner wall of the mold, and after cooling and demoulding, various hollow bottle products can be obtained. Blow molding machines can be divided into three categories: extrusion blow molding machines, injection blow molding machines and special structure blow molding machines. Extrusion blow molding machine is a combination of extruder, blow molding machine and mold clamping mechanism. It is composed of extruder, parison die head, inflation device, mold clamping mechanism, parison thickness control system and transmission mechanism. Injecti...

Problems solved by technology

According to the above blow-molded plastic processing equipment, there are: only one or two can be molded at a time, and the production efficiency is low, resulting in relatively high cost and high energy consumption. Although this type of bottle-making equipment has been partially optimized and improved for many years , but failed to fundamentally solve the problem
