Embodiment Construction

[0046] In order to make the object, technical solution and advantages of the present invention clearer, the method for optimal design of the ceramic injection mold and the specific implementation of the ceramic injection mold of the present invention will be described below with reference to the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047] The ceramic injection mold optimization design method of the present invention is used for designing the ceramic injection mold, especially the injection flow channel in the ceramic injection mold with reasonable design and good injection molding effect. And the design of the present invention is mainly aimed at a multi-cavity ceramic injection mold. For this type of ceramic injection mold, each mold includes at least two cavities of ceramic products. Of course, in general, the cavities of two different ...

Abstract

The invention discloses a ceramic injection mould optimal design method and a ceramic injection mould. The optimal design method includes the following steps that a required ceramic injection mould model is designed through mould design software to serve as an original ceramic injection mould needing to be optimized; a 3D mould model of the original ceramic injection mould is guided out and guided into simulation software; an initial injection moudling channel allowing injection moulding materials to flow into a cavity is built in the 3D model; the 3D model is subjected to ceramic injection moulding forming process simulation through simulation software, and the difference of injection moudling time required by injection moulding of two ceramic products is recorded; whether the injection moulding time is within a preset time range is judged, and the injection moulding channel built in the original ceramic injection mould is improved till injection moulding time difference is within a preset time range. The software is used for injection moulding process simulation, cost in the mould development process is greatly reduced, and mould development and design efficiency is improved. The precision and the quality of the ceramic products are guaranteed, and meanwhile waste of ceramic materials is reduced.

Description

technical field [0001] The invention relates to the technical field of ceramic injection molding, in particular to a ceramic injection mold optimization design method and a ceramic injection mold. Background technique [0002] In the process of making ceramic injection molds, the flow channel balance of one mold with multiple cavities (a set of molds with multiple products with different sizes, each product corresponding to a cavity) is very important. In the past, the size of the flow channel was generally designed through experience, but in order to achieve a flow balance of the ceramic melt in the cavity, it was necessary to perform multiple mold modifications to change the flow channel in the mold. And every time it is necessary to make a re-modified mold, and use injection molding materials to inject the modified mold to judge whether the mold has reached the requirement again. Such a mold design process often results in long product development time and waste of cost....
