Injection mold manufacturing method based on CAD/CAE/CAM and products

Abstract

The invention relates to an injection mold manufacturing method based on CAD / CAE / CAM. The method includes the steps of a, designing a mold, to be more specific, using three-dimensional software to build 3D models of the structural parts of the mold, and manufacturing the general assembly drawing of the mold; b, manufacturing the engineering drawing of each part and setting a mold tolerance standard; c, manufacturing the injection mold, to be more specific, CAM tool path programming and importing a CNC manufacturing process, an EEM manufacturing process, a WEEM manufacturing process and a grinding process; d, soaking the mold in special plant oil for more than 24 hours; e, detecting the mold. The method has the advantages that a mold prototype drawing CAD design link can avoid problems in actual machining according to graphic simulation analysis, overall mold design is further optimized, and subsequent processes can be implemented reliably; due to the fact that the mold is soaked in the plant oil for more than 24 hours, the precision of the mold can be increased evidently, the service life of the mold is prolonged evidently, and the yield of injection molding products is increased evidently.

Description

technical field [0001] The invention relates to digital mold design and manufacturing technology, in particular to a CAD / CAE / CAM-based injection mold manufacturing method and products. Background technique [0002] Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products complete structure and precise dimensions. Its application must be extensive. [0003] Injection molds are generally composed of a moving mold and a fixed mold. The moving mold is installed on the moving template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form the gating system and the cavity, and the movable mold and the fixed mold are separated to take out the plastic product when the mold is opened. [0004] Although the structure of the mold may vary due to the variety and performance of the plastic, the ...

AI Technical Summary

Problems solved by technology

[0006] The traditional manufacturing method of injection mold is relatively simple, and the precision is low in the process of design, manufacture, and inspection, and there may be bad surfaces, which will cause the tool to be raised and affect the machining accuracy. In addition, a complete and systematic process flow has not been established, resulting in After the mold cavity is processed, it is inevitable that it will take a lot of energy and time to repeatedly try the mold and modify the product parameters and mold parameters, and it is impossible to quickly achieve the effect of zero FIT mold

[0007] In addition, the surface properties of molds processed and treated by existing methods cannot fully meet the requirements, which affects the quality of injection molding products and the service life of molds
