Description

Technical Field

[0001] The invention relates to a rod injection molding device. Background Art

[0002] For some accessories, such as rod-type accessories, the main part of the rod can be made of strong metal materials such as aluminum or stainless steel, and the end or middle part of the rod can be formed into various shapes of plastic or plastic-like materials by a glue injection machine, such as forming a connecting part, to facilitate matching with other accessories. Compared with metal molding, the injection molding temperature is lower and the injection mold is easier to design. Traditional glue injection machines of this type generally manually place the rod in the injection mold of the glue injection device. After the glue injection is completed at the corresponding position of the rod, the injected rod is ejected by the ejector mechanism, and then the excess sprue material is removed. The overall processing efficiency is relatively low, the labor intensity is high, and the stability is relatively poor. Especially for some long rods, during injection molding, some parts of the rod do not need to be injected, and they extend outside the mold. If the material is not released accurately, it will affect the accuracy of injection molding.
