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. The feeding device comprises a mixing box, a first shell, a second shell, a cleaning mechanism and a drying mechanism. A feeding openingis formed in the bottom of the mixing box. A feed opening communicating with the feeding opening is formed in the top face of the first shell, and a first discharge opening is formed in the bottom face of the first shell. The second shell is of a barrel structure with an opening formed in the upper end, and a second discharge opening is formed in the bottom face of the second shell. The cleaningmechanism comprises multiple guide components, multiple drainage pipes, multiple sets of sweeping components, a first guide plate and two second guide plates. The drying mechanism comprises a spiral pipe, a disc and a rotating shaft. According to the feeding device, plastic particles can be subjected to pretreatment of cleaning dust removal and drying dehumidification, the quality of the raw material plastic particles can be improved, it can be guaranteed that raw materials are heated uniformly in the subsequent hot melting injection molding process, molten liquid is balanced in concentrationand free of bubbles, then the quality of a plastic shell product is improved, and the service life of a plastic shell is prolonged.

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...
