Problems solved by technology

[0003] Traditional injection molding machines do not have supporting feeding devices. Granular plastic raw materials are usually directly put into the injection molding machine, and then heated by the screw. A large amount of dust and moisture are adsorbed on the outer surface of the plastic, which causes air bubbles to affect the subsequent hot-melt injection molding process. The quality and service life of plastic case products

Abstract

The invention discloses a feeding device for an injection mold, which comprises: a mixing box, the bottom of which is provided with a feeding port; The discharge port; the second shell, which is a cylinder structure with an open upper end, and the bottom surface of the second shell is provided with a second discharge port; the cleaning mechanism, which includes a plurality of material guide parts, a plurality of drainage pipes, a plurality of sets A cleaning component, a first material guide plate and two second material guide plates; a drying mechanism, which includes a spiral tube, a disc and a rotating shaft. The invention can carry out pretreatment of cleaning, dust removal, drying and dehumidification of plastic particles, improve the quality of raw material plastic particles, ensure that the raw materials are heated evenly in the subsequent hot-melt injection molding process, and the concentration of the molten liquid is balanced without bubbles, thereby improving the quality of plastic shell products and prolonging the life of plastic products. The service life of the plastic case.

Description

technical field [0001] The invention relates to the technical field of plastic case processing. More specifically, the present invention relates to a feeding device for an injection mold. Background technique [0002] Molded case refers to the use of plastic insulators as the casing of the device to isolate conductors and grounded metal parts. Injection molding machine is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. It is one of the main equipment for plastic case processing. [0003] Traditional injection molding machines do not have supporting feeding devices. Granular plastic raw materials are usually directly put into the injection molding machine, and then heated by the screw. A large amount of dust and moisture are adsorbed on the outer surface of the plastic, which causes air bubbles to affect the subsequent hot-melt injection molding process. The quality and serv...
