A hot runner mold with multiple hot gates

Abstract

The invention discloses a hot runner mold with a multipoint hot gate, comprising an upper mold plate, heat barriers and an overload protector. The bottom end of the upper mold plate is provided with abottom mold plate that is releasably connected with the upper mold plate; the end of the upper mold plate far away from the bottom mold plate is provided with an insulation plate; the insulation plate is fixedly connected with the upper mold plate; the heat barriers are distinguished via connectors and are mounted in separate zones; a hot divider plate can be opened through a mounting cover, so that the heat barriers are convenient to mount, maintain and replace, maintenance speed for the damaged heat barriers is increased, and time and manpower are saved, with working efficiency of the hot runner mold ensured; a filter mesh plate can filter off metal particles in melt so that the metal particles are avoided blocking an injection nozzle or causing damage to the injection nozzle; the overload protector can protect the safety of the heat barriers in other zones when the heat barriers mounted the separate zones fail, so that maintenance cost is lowered, and normal running of the hot runner mold is ensured.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a hot runner mold with multi-point hot gates. Background technique [0002] The hot runner mold is a mold that uses a heating device to keep the melt in the runner from solidifying. Because it has a shorter forming cycle than traditional molds and saves more raw materials, hot runner molds are widely used in various industrially developed countries and regions in the world today. [0003] The original hot runner mold with multi-point hot gate still has some shortcomings. During the use of the hot runner mold, the heat splitter plate may be short-circuited and cannot be used normally, resulting in damage to the thermal resistance strip, and the thermal resistance strip Maintenance is troublesome, time-consuming and labor-intensive, which affects the working efficiency of the hot runner mold. Contents of the invention [0004] The purpose of the present invention is ...
