One-step three-station injecting, drawing and blowing plastic molding machine

Abstract

The invention provides a one-step three-station injecting, drawing and blowing plastic molding machine which comprises a mounting base, a fixing frame, an injection device, an injection bottle blank component, a rotating template assembly, a pre-blowing mould component, a drawing blowing component and a product de-molding component, wherein the fixing frame is arranged on one side of the mounting base; the injection device is arranged on the mounting base; the injection bottle blank component is fixed on the fixing frame; the rotating template assembly is fixed on the fixing frame; the pre-blowing mould component is fixed on the mounting base; the drawing blowing component is fixed on the fixing frame; the product de-molding component is fixed on the fixing frame; the injection bottle blank component is injected and molded into a semi-finished product bottle blank in an injection bottle blank mould; an injection mould core lifting cylinder is used for driving the semi-finished product bottle blank to ascend; an injection bottle blank mould lifting cylinder is used for driving the semi-finished product bottle blank to descend; and then a rotary power motor is used for driving the rotating template assembly to rotate, thereby driving the semi-finished product bottle blank to enter into a drawing blowing molding mould; and an end product is drawn, blown and molded after the temperature is adjusted by a temperature adjusting cylinder, or the pre-blowing mould component is used for adjusting the temperature and drawing, thereby obtaining a semi-finished product bottle after pre-blowing, and then the drawing blowing molding mould is used for blowing and molding, thereby forming the end product.

Description

technical field [0001] The invention relates to the technical field of plastic molding devices, in particular to a one-step injection stretch blow plastic molding machine. Background technique [0002] The existing traditional hollow product molding adopts a "two-step method". The first step is to prepare the preform on the injection molding machine and take it off manually; the second step is to heat the injected preform and take it to the blow molding machine for blow molding. forming. This not only causes the pollution of the preform during the transfer process, but also wastes electricity, increases the footprint of the injection molding machine and the turnover space of the preform, and increases labor costs. Based on the many disadvantages of the above-mentioned "two-step method", a "two-step method" gradually emerges One-step injection stretch-blow plastics are used to make products. However, the existing one-step injection stretch blow molding machines in China are ...

Problems solved by technology

This not only causes the pollution of the preform during the transfer process, but also wastes electricity, increases the footprint of the injection molding machine and the turnover space of the preform, and increases labor costs. Based on the many disadvantages of the above-mentioned "two-step method", a " One-step "injection stretch blowing plastics production method, but the existing domestic one-step injection stretch blowing plastic molding machine is not yet mature, the product quality is not up to the standard, only to rely on imports
