Injection molding feeding device

Abstract

The invention discloses an injection molding feeding device, and relates to the technical field of injection molding. The injection molding feeding device comprises a material conveying box, wherein a conveying pipe is fixedly mounted at the bottom of the material conveying box, a material conveying hole is formed in the position, corresponding to the bottom of the material conveying box, of the inner side of the conveying pipe, a limiting shaft is arranged at the right end of the inner side of the conveying pipe, the right end of the limiting shaft is fixedly connected with an output shaft of an injection molding device driving device, and an injection molding screw rod is fixedly mounted at the left end of the limiting shaft. According to the injection molding feeding device, along with rotating and rising of an inner adjusting plate, the inner adjusting plate and a plugging adjusting plate can generate pressure on the inner portion of a limiting air block, so that air pressure expands spiral arc blocks and side arc plates on an expanding arc plate and an auxiliary dredging pipe, the storage density of raw materials in the material conveying box is compressed, in this way, after a limiting shaft shrinks, the spiral arc blocks and the side arc plates on the expanding arc plate and the auxiliary dredging pipe shrink, then the storage density in the material conveying box is expanded, and therefore, the effect of carding the raw materials in the material conveying box is achieved.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to an injection molding feeding device. Background technique [0002] In the injection molding operation, the plastic granule raw materials are usually transported to the inside of the injection pipe through the conveying device and the feeding box, and the injection molding screw and the end of the injection pipe inside the injection molding tube can carry out injection molding on the telescopic rod that seals the bottom of the feeding box, but , when the injection molding screw is performing injection molding operations, the telescopic rod that can be sealed at the end of the injection molding screw will seal the bottom of the feeding box. characteristics, so that the raw materials inside the upper material box are extruded and adapted to shrink. When the extrusion shrinks to the appropriate degree, the plastic raw materials will be buckled inside the upper material box,...

When the extrusion shrinks to the appropriate degree, the plastic raw materials will be buckled inside the upper material box, causing blockage. For this reason, we propose An injection molding feeding device
