Feeding device for injection mold

Abstract

The present invention relates to the technical field of chemical equipment, in particular to a feeding device for injection molds, including a stirring box, a dust collector, a high-pressure fan assembly, a propulsion device and a support frame. A second motor is fixedly connected to the center of the top of the stirring box, and The end of the main shaft of the second motor is fixedly connected with a vertical stirring rod, and the right side of the stirring box is fixedly connected with a hot air blower, which can dry and dehumidify the plastic raw materials. The dust device includes a dust removal box, an air guide pipe and a dust removal filter element, which can remove dust from plastic raw materials. The propulsion device includes a propulsion tube, a first motor and a propulsion screw, and the top left side of the propulsion tube is provided with a material inlet; A collecting hopper is fixedly connected to the bottom end of the stirring tank, and the bottom end of the collecting hopper is fixedly connected to the propulsion pipe. The structure of the present invention is scientific and reasonable, has huge economic benefits and wide market demand, and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a feeding device for an injection mold. Background technique [0002] Injection molding is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain complex-shaped parts. The injection molding machine is injected into the mold cavity under high pressure, and after cooling and solidification, the molded product is obtained. With the continuous development of the times, the use of plastic products is becoming wider and wider. Therefore, the demand for injection molds is increasing day by day. [0003] At present, the injection mold feeding devices on the market directly push the plastic raw materials into the barrel of the injection molding machine under high pressure, without dehumidification and dust removal for the plastic...

AI Technical Summary

Problems solved by technology

[0003] At present, the injection mold feeding devices on the market directly push the plastic raw materials into the barrel of the injection molding machine under high pressure, without dehumidification and dust removal for the plastic raw materials, because a large amount of dust and impurities will be mixed in the plastic raw materials during the production, processing, transportation and mixing process , if it is not treated, it will seriously affect the quality of the molded plastic, and because many plastic raw materials have strong hygroscopicity, the water content must be reduced before the product is formed to avoid air bubbles in the subsequent hot-melt injection molding process that will affect the quality and service life of the product. , Aiming at the above problems, a feeding device for injection molds is proposed
