Vertical shaft type automatic mold opening device and injection molding machine for a disc type injection molding machine

Abstract

The invention provides a vertical rotation shaft type automatic mold opening device of a disc type injection molding machine. The vertical rotation shaft type automatic mold opening device comprises a frame body, a mold opening actuator and a lift-preventing device; the mold opening actuator is provided with an upslope inclination side, and the upslope inclination side is gradually heightened in the rotation direction of a disc. In the actual use process of the device, at the joint between a buckle handle and the upslope inclination side, the buckle handle receives the upward thrust of the upslope inclination side along with continuous operation of the disc, the lift-preventing device limits a mold bottom plate so that a lower mold cannot be lifted, after the buckle handle walks on the upslope inclination side for a certain distance, the upslope inclination side can completely separate an upper mold and the lower mold, and therefore automatic mold opening can be realized in the operation process of the disc, and continuous and automatic mold opening can be realized in the continuous operation process of the disc. In the actual work process, the frame body bears the mold opening actuator and enables the mold opening actuator to get close to or away from the disc through a vertical rotation shaft in a door opening and closing mode; the structure is simple and reasonable and the movement is simple. 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 vertical shaft type automatic mold opening device for a disc type 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...

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.
