Injection molding process of fine-tune type dust collector shell

Abstract

The invention relates to an injection molding process of a fine-tune type dust collector shell, and belongs to the technical field of injection molding processes. Clay minerals and metal oxides are added to injection molding raw materials, so that the mechanical strength and aging resistance of the injection molding materials are effectively improved. Moreover, materials with high mechanical strength are mixed with nano magnet powder, and the nano magnet powder is adsorbed in the porous-structure materials with high resistance. An external electromagnet is arranged at the corresponding position of a cavity of an injection mold, and after the external electromagnet is electrified, the flow direction of the injection molding materials with high mechanical strength is fine tuned in the injection molding process. Even if the materials with high mechanical strength are gathered to a designated position under the magnetic effect, the use requirements of the end face of an existing dust collector shell for different strengths can be better met. Gas in the injection mold can be easily absorbed and discharged in the mold closing process, and when the mold is opened, the gas which is pushedout effectively blows chips adhered to the parting surface of the mold.

Description

Technical field [0001] The invention relates to the technical field of injection molding technology, in particular to an injection molding process of a micro-adjustable vacuum cleaner housing. Background technique [0002] In modern society, vacuum cleaners are becoming products in people's lives, and its development drives the rise of a series of scientific and technological fields. With the continuous maturity of vacuum cleaner products and the change of people's consumption concepts, the quality, function and appearance of vacuum cleaners have become the focus of competition among businesses. [0003] Existing vacuum cleaner shells have different requirements for stress points, and the tolerance of the shell surface is also different. In the prior art, in the injection molding process, the mechanical hardness of the molten injection plastic injected into the mold is often They are all the same, so the hardness of the produced shells are all the same, so it is difficult to adapt...

Problems solved by technology

This method has poor exhaust and low efficiency. In many plastic molds, the mold exhaust requirements cannot be met, resulting in poor filling of the product, resulting in poor smoothness and flatness of the product.
