Industrial robot for injection molding production

Abstract

The invention relates to the field of industrial robots, in particular to an industrial robot for injection molding production, which comprises a cylinder body, a pushing part is arranged on the inner side of the cylinder body, a feeding part is arranged on the side surface of the cylinder body close to the upper end, and a communicated injection molding pipe is arranged at the lower end of the cylinder body. The mold comprises an injection molding pipe, the position, close to the lower end, of the outer surface of the injection molding pipe is slidably sleeved with a sleeve through an elastic mechanism, the lower end face of the sleeve is provided with a plurality of sealing plates which are in sliding fit with the sleeve, the sealing plates are arranged in an annular array, and the lower end of the sleeve is jointly sealed by the sealing plates. The step of reverse pressure relief after screw propulsion is omitted, the self-plugging function is achieved, meanwhile, molding particles at the end of an injection molding material can be removed during injection molding, the possibility of plugging is effectively reduced, meanwhile, the self-plugging device can be applied to the environment with long adjacent injection molding intervals, the universality is better, and the injection molding stability is improved.

Description

technical field [0001] The invention relates to the field of industrial robots, in particular to an industrial robot for injection molding production. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Plastic injection molding is a method of plastic products. The molten plastic is injected into the mold of plastic products by pressure, and the various plastic parts are obtained by cooling and molding. There are mechanical equipment specially used for injection molding. At present, the most commonly used plastics are polyethylene, polypropylene, ABS, PA, polystyrene, etc., while existing industrial robots use screw propulsion in the process of injection molding. Push the injection molding, and after the injection is completed, the screw will rotate in the opposite direction to reduce the pressure at the end of the injection pipe and prevent the ...

AI Technical Summary

Problems solved by technology

There are mechanical equipment specially used for injection molding. At present, the most commonly used plastics are polyethylene, polypropylene, ABS, PA, polystyrene, etc., and the existing industrial robots use screw propulsion during the injection molding process. Push injection molding, and after the injection is completed, the screw will rotate in reverse to reduce the pressure at the end of the injection tube and prevent the injection material from ejecting during the demoulding process. Therefore, during the injection molding production process, the screw is intermittently positive Inversion requires two processes, and the corresponding parameters need to be input for the servo equipment. In actual use, maintenance and operation are more inconvenient. In addition, the injection plastic at the port is prone to cooling and hardening. Therefore, in the continuous injection molding process, In the case of poor heat control at the port and too long injection intervals, the port is prone to blockage, which brings inconvenience
