Problems solved by technology

[0003] Because the traditional manifold flow channel processing technology is mostly processed by gun drilling, the process of using gun drilling to process hot runner is more complicated, and sharp corner transitions will be formed at the corners of the flow channel, which will cause large pressure loss during injection molding. , and it will bring high shear heat and color change troubles, especially for complex flow channels, the existing manifold flow channel processing technology is difficult to meet customer requirements

Abstract

The invention provides a 3D printing channel splitter plate processing technology. The technology comprises directly printing a metal channel by a 3D printing technology, carrying out metal casting on the metal channel and a splitter plate obtained by preliminary machining molding so that the metal channel and the splitter plate are assembled into an integral body, and carrying out machining molding. A drill gun is used for processing a channel so that processes are simple, the 3D printing channel has any shape so that the 3D printing channel is suitable for complex channel processing, the channel prepared by a 3D printing technology has smooth inner holes and corners with circular arc transition so that pressure loss is small, shearing heat is small and color change in injection molding is fast and convenient.

Description

technical field [0001] The invention relates to a hot runner system, in particular to a process for processing a splitter plate of the hot runner system. Background technique [0002] A hot runner is a collection of heating components used in injection molds to inject molten plastic into the cavity of the mold. The hot runner system generally consists of several parts such as hot nozzles, manifolds, temperature control boxes and accessories. The hot runner manifold is the central part of the hot runner system, which distributes the plastic melt from the main runner nozzle to each injection point nozzle through the runner. The splitter plate can make the cavity of the mold be filled evenly, the plastic flow is balanced, and the system heat is balanced. The diverter plate series include X type, H type, I type, Y type, K type and others. There are two heating methods for the hot runner manifold, one is internal heating, that is, setting the heating rod in the runner to heat ...
