Automatic mold opening device for injection molding machine and injection molding machine composed of same

Abstract

The invention provides an automatic mold opening device for an injection molding machine. The automatic mold opening device comprises a rack body, a mold-opening execution mechanism and an anti-lifting device. The mold-opening execution mechanism is provided with an upslope bevel edge, and the upslope bevel edge is changed to be higher gradually in the rotation direction of a disc. In this way, in the practical application process of the automatic mold opening device, the connection position of a buckle handle and the upslope bevel edge continues to operate along with the disc; the buckle handle is subjected to upward pushing force of the upslope bevel edge; the anti-lifting device limits a mold bottom plate, and consequently a lower mold cannot be lifted; after the buckle handle travels for a certain distance on the upslope bevel edge, an upper mold and the lower mold can be separated completely through the upslope bevel edge; in the operation process of the disc, automatic mold opening can be achieved; and in the continuous operation process of the disc, continuous automatic mold opening is achieved. By means of the mold-opening execution mechanism which is of a frame structure and in the form of metal tubes or metal rods, on the basis that structural strength is guaranteed, material consumption and weight are greatly reduced; cost is remarkably lowered; and practicability is remarkably improved. 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 an automatic mold opening device for an 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 installed on the t...

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.
