Plastic bottle plastic injection mold opening and taking manipulator

Abstract

The invention discloses a plastic bottle plastic injection mold opening and taking manipulator. The manipulator structurally comprises a fixing base, an adjusting motor, and a grabbing frame; the fixing base is fixedly connected with the rear side of the grabbing frame in an embedded mode; the adjusting motor is in threaded connection with the upper side of the fixing base; the grabbing frame comprises a cooling device, a bending base, a push rod, an arc rod, and clamping heads; the cooling device is fixedly connected with the front end of the fixing device in an embedded mode. The push rod drives a push disc at the inner side of an outer cover to move upwards, then cooling liquid is pumped into a connecting pipe through a one-way valve, and then claw heads are cooled through flowing of afirst connecting rod and a second connecting rod of the connecting pipe, so that the cooling speed of the clamping heads is increased, and meanwhile the bottle cap grabbing speed is increased; and a linkage frame in a threaded ring shakes towards the left side, so that the inner side of a threaded cover is extruded into an arc to be ejected outwards to push out adhesive wires adhered to the innerside of the threaded cover, so that the number of the adhered clamping heads is reduced, and the grabbing stability of the clamping heads is improved.

Description

technical field [0001] The invention belongs to the field of injection mold opening, and more specifically relates to a manipulator for plastic bottle injection mold opening and pick-up. Background technique [0002] The plastic bottle mold opening and picking manipulator is a manipulator used to pick up the plastic bottle mold opening. In modern industry, the mold taking manipulator grabs the bottle mouth and places the preform to improve the manufacturing speed of plastic bottles. However, due to the The grasping frequency is too high, resulting in that the temperature of the bottle mouth will not be lowered when the bottle body is placed, and it will adhere to the outside of the gripping head of the manipulator, which will damage the thread structure of the bottle mouth and reduce the strength of the bottle mouth, making the blow molding process There will be a demoulding phenomenon, and the bottle mouth will adhere to the outside of the manipulator with residual plastic ...

In modern industry, the mold taking manipulator grabs the bottle mouth and places the preform to improve the manufacturing speed of plastic bottles. However, due to the The grasping frequency is too high, resulting in that the temperature of the bottle mouth will not be lowered when the bottle body is placed, and it will adhere to the outside of the gripping head of the manipulator, which will damage the thread structure of the bottle mouth and reduce the strength of the bottle mouth, making the blow molding process There will be a demoulding phenomenon, and the bottle mouth will adhere to the outside of the manipulator with residual plastic sticky wire. The sticky wire will harden after cooling, which will cause the surface of the gripping head of the manipulator to not match the bottle mouth, making subsequent clamping difficult, and even causing the preform to fall. , the machine is stuck
