The invention discloses an automatic injection device for a two-color plastic rain boot injection molding machine, and belongs to injection molding equipment. A feed port is formed in the rear end of a die head. A threaded rod bushing is fixedly arranged at the feed port. A feeding threaded rod is sleeved in the threaded rod bushing, and is connected with the feed port. A material sealing head is arranged in the feed port. A runner is formed in the die head. The head part of the runner is connected with the material sealing head. A bushing hole is formed in the front end of the die head, and a pull rod bushing is arranged in the bushing hole in an inserting manner. The head part of the pull rod bushing is fixedly arranged on the die head, and a through hole is formed in the tail part of the pull rod bushing. The pull rod bushing is perpendicular to the runner. The runner penetrates through the through hole in the tail part of the pull rod bushing, and reaches the bottom of the die head. A pull rod is arranged in the pull rod bushing in the inserting manner. The head part of the pull rod is connected with a piston of a cylinder, and the tail part of the pull rod and the runner are movably sealed. The automatic injection device has the advantages that materials can be smoothly injected, blockage and industrial accidents are avoided, the quality of a product is improved, and the automatic injection device is high in production efficiency, safe, reliable and fully automatic.
Description
technical field [0001] The invention belongs to injection molding equipment, and more specifically relates to an automatic injection device for a double-color plastic rain boot injection molding machine. Background technique [0002] At present, the injection nozzle of the two-color plastic rain boots injection molding machine is a nozzle set inside an outer screw sleeve. There is a discharge port around the nozzle, and the outer screw sleeve is connected to the outlet end of the flow channel in the die head. When the injection nozzle of this structure injects raw materials, the nozzle is lifted up through the mold to form a certain gap between the nozzle and the outer screw sleeve, and then the glue is injected from the outlet around the nozzle. Because the gap between the nozzle and the outer screw sleeve is small, the material is often blocked in the gap between the outer screw sleeve and the nozzle, so that the injection molding machine cannot work normally. At this time...
