Injection-molded component manufacturing method

Abstract

The invention provides an injection-molded component manufacturing method for inserting an iron insert part into an injection-molded blank which is injection-molded in an injection mold of an injection molding machine so as to obtain an injection-molded component by means of integral formation. The injection-molded component manufacturing method is characterized by adopting the injection molding machine, the injection mold connected with the injection molding machine, an insert part placing device for inserting an iron metal insert part, and an injection-molded component manufacturing system of a control device for manufacturing, and the specific manufacturing method is shown in the abstract and attached drawings. By designing a set of injection-molded component manufacturing system and manufacturing method, the insert part is placed at a preset position of the mold in an injection molding process of the injection molding machine so that the metal insert part can be inserted by just preforming or designing one connecting opening in the existing injection mold, and thus the cost is lowered, the design is simplified, and an existing mold can be used just after being simply modified.

Description

technical field [0001] The invention relates to the field of injection molded parts production machinery, in particular to a mechanical system for embedding metal parts into injection molded parts, and belongs to the field of injection molded parts processing. Background technique [0002] In automobile manufacturing and other related fields, it is necessary to make such parts: some parts are embedded in metal parts on injection molded plastic parts. There are roughly two methods for making such parts. One is to pour the embedding holes in the predetermined parts of the plastic parts, and then press or bond the inserts non-detachably. This situation is mostly suitable for embedding nuts or bolts; the other is The first method is to place the part to be embedded on the casting mold when the plastic part is poured, and pour the insert directly on the plastic part. [0003] Obviously, the former method is not as good as the latter's integrated casting method in terms of manufa...

AI Technical Summary

Problems solved by technology

[0004] First of all, the cost is high, and the pouring mold needs to be designed separately for different parts, and for the same injection molded part but different inserts, the pouring mold needs to be remade, or the cavity corresponding to the insert is processed in the cavity of the existing mold. groove;

[0005] Secondly, the operation is complicated. Every time before pouring, the mold must be opened to place the insert to be embedded in the predetermined position, which is not easy to operate and seriously affects the production efficiency.
