One-step method injection molding stretching and blowing forming integration machine and one-step method injection molding stretching and blowing forming machining method

Abstract

The invention belongs to the technical field of plastic product forming devices, and particularly relates to a one-step method injection molding stretching and blowing forming integration machine and a one-step method injection molding stretching and blowing forming machining method. The machine comprises a machine frame, an injection molding device, a bottle blank forming mold, a heating and bottle blowing forming device, a first mechanical hand device and a second mechanical hand device. The injection molding device, the bottle blank forming mold, the first mechanical hand device and the heating and bottle blowing forming device are sequentially arranged on the machine frame, and the second mechanical hand device is arranged beside the heating and bottle blowing forming device. The injection molding device injects plasticized plastic into the bottle blank forming mold, a bottle blank is cooled and formed in a bottle blank forming cavity of the bottle blank forming mold, and then the first mechanical hand device takes out the cooled and formed bottle blank; and then the second mechanical hand device transfers the bottle blank clamped on the first mechanical hand device to the heating and bottle blowing forming device, finally the heating and bottle blowing forming device conducts heating and bottle blowing working procedures on the bottle blank, and a formed bottle body is obtained.

Description

technical field [0001] The invention belongs to the technical field of plastic product molding devices, and in particular relates to a one-step injection stretch blow molding machine and a processing method thereof. Background technique [0002] With the continuous development of the demand for plastic parts, the methods of plastic processing are also constantly updated. Injection molding is one of the main plastic molding processing methods; the so-called injection molding is to heat thermoplastics (PC, PE, PS, PP, PVC, PA, ABS, etc.) After melting, inject it into a mold with a cooling device at a certain injection pressure, and obtain various plastic products after rapid cooling. However, simple injection molding is difficult to meet the requirements for some high-demanding beverage bottles, water bottles, hanging bottles or medicine bottles. As the mainstream processing technology for plastic hollow containers, "injection stretch blowing" and "multiple Layer co-extrusio...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a one-step injection stretch blow molding integrated machine and its processing method, aiming to solve the multi-station "one step" injection stretch blow molding equipment in the prior art, which adopts the form of a turntable for processing. The position is connected, which causes the turntable to swing back and forth every time it moves to a processing station, so that the turntable can stop stably and accurately, which takes a long time and has low stability, which affects the production efficiency and product quality.
