Slide rail type automatic mold opening device of injection molding machine and injection molding machine composed of same

Abstract

The invention provides a slide rail type automatic mold opening device of an injection molding machine. At the joint of a buckle handle and an upslope bevel edge, along with continuous operation of a disk, the buckle handle bears upward push force of the upslope bevel edge, and an anti-uplift device limits a mold bottom plate so that a lower mold cannot be lifted up; after the buckle handle moves a certain distance on the upslope bevel edge, the upslope bevel edge can enable an upper mold to be completely separated from the lower mold; and accordingly, automatic mold opening can be realized in the operating process of the disk, and continuous and automatic mold opening can be realized in the continuous operating process of the disk. Moreover, by adopting a frame structure, a metal tube or a mold opening execution mechanism of a metal bar form, on the basis of guaranteeing the structural strength, consumption and weight of materials can be greatly reduced, the cost is remarkably lowered, and the practicality is improved. Furthermore, a frame is borne by a slide rail, the whole mold opening execution mechanism can get close to or away from the disk through guidance and carrying of the slide rail, so that various molds are opened in due time, or mold opening is stopped. The invention further provides the injection molding machine.

Description

technical field [0001] The invention relates to the field of injection molding machinery, in particular to a slide rail type automatic mold opening device of the injection molding machine and an injection molding machine with the automatic mold opening device. Background technique [0002] The structure of the disc type injection molding machine is known, such as the Chinese utility model patent CN201320005864.3, a kind of shoe sole injection molding equipment, including a blower, a preheating and cooling device, a mold and a supporting plate; the blower includes a goose head structure and a turntable; the preheating and cooling device includes a cooling fan, a heating rod and an airtight chamber, the preheating and cooling device is fixed on the goose head structure, and the heating rod is fixed inside the airtight chamber, so The cooling fan is fixed outside the airtight cavity; the mold is installed on the upper end of the supporting plate, and the supporting plate is ins...

Problems solved by technology

[0004] In the actual injection molding process of the aforementioned injection molding machine and mold, it is usually necessary to manually use tools such as metal sticks to knock the buckle structure of the mold, and then insert the metal stick etc. into the gap between the upper mold and the lower mold, and press the Pry open the upper mold, and then push it up to fully open the upper mold. This manual mold opening process is time-consuming, laborious, inefficient, poor mold opening quality, and harmful to the mold itself. Moreover, the heated mold will pose a safety threat to people.
