Precise injection mold capable of eliminating weld line

Technical Field

The utility model relates to an accurate injection mold technical field, concretely relates to can eliminate accurate injection mold of weld line.

Background

A precision injection mold is a device in which a resin material is injected into a metal mold to obtain a product having a predetermined shape. In fact, in order to control the temperature of the mold, there are also devices such as cooling holes for passing a refrigerant, heaters, and the like. The material which becomes melt enters the main runner, passes through the sub-runners and the sprue and is injected into the die cavity. After the cooling stage, the mold is opened, and the ejector rod is ejected out by the ejector device on the forming machine to push out the product. The molded article is composed of a main runner for flowing a molten resin, a sub-runner for guiding the molten resin into a cavity, and a product. We usually design the lengths of the sub-runners to be equal. The main runner and the sub-runners of the returned molded article are not products, and may be discarded or pulverized and reused as a molding material. We call it a feed back. The recycled materials are not generally used alone as molding materials, but are usually used after being mixed with virgin materials. This is because the mechanical properties, flowability, color and other properties of the resin change after the primary molding.
