Hollow forming machine for one-step injection, drawing and blowing of plastic

Abstract

The invention discloses a hollow forming machine for one-step injection, drawing and blowing of plastic, comprising a mounting base, an injection device which is arranged at one side of the mounting base, a fixed mount which is arranged at the other side of the mounting base, a bottle embryo injection assembly which is fixed on the fixed mount, a temperature adjustment device, an blowing-drawing assembly, a blow-molding clamping mechanism assembly which is arranged on the mounting base and matched with the blowing-drawing assembly, a rotary die plate assembly, an injection station which is arranged below the bottle embryo injection assembly and used for placing a bottle embryo die, a product de-molding assembly and a rapid die change mechanism, wherein a power motor is arranged above the rotary die plate assembly and used for driving the rotary die plate assembly to rotate and a fixed mount lifting cylinder is arranged below the rotary die plate assembly; a semi-finished bottle embryois injection-molded in the bottle embryo die via the bottle embryo injection assembly; the fixed mount lifting cylinder drives the rotary die plate assembly to rise and then the power motor drives the rotary die plate assembly to rotate so that the semi-finished bottle embryo is driven to enter the position of a drawing-blowing die; and under the driving of the cylinder, the rotary die plate assembly falls into the drawing-blowing die; and drawing and blow molding are carried out by the drawing-blowing assembly so that the finished bottle is obtained.

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 hollow 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 hollow products. However, the existing domestic one-step injection stretch-blow plastic...

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-blow plastic" method for making hollow products, however, the existing domestic one-step injection stretch-blow plastic hollow molding machines are immature, and the product quality is not up to standard, so they can only rely on imports
