Method for manufacturing injection mold

Abstract

The invention belongs to the field of a frontier of mold processing and manufacturing and in particular relates to a method for manufacturing a zero FIT injection mold. The method comprises the following steps: performing CAM tool path process design, performing a numerical control machining process, performing electric spark and wire-electrode cutting machining, performing grinding machine processing and performing mold detection according to mold design, engineering drawing manufacturing, mold tolerance standard setting and mold processing. After the mold processing and manufacturing operation is finished, the assembling requirements can be met, and the manufacturing precision of the mold is greatly improved, so that qualified products are obtained at a time, and the cumbersome process of performing repeated mold testing and modifying product parameters and mold parameters is avoided after the mold processing is finished. The method is high in practicability and good in service effect and can be widely popularized and applied in the field of manufacturing of injection molds.

Description

[0001] technical field [0002] The invention relates to the field of mold processing and manufacturing, mainly relates to a zero-FIT mold control technology, and specifically relates to a manufacturing method of an injection mold. Background technique [0003] The production scale of my country's mold industry now accounts for nearly 10% of the world's total, ranking third in the world, second only to Japan and the United States. Moreover, the supply of molds with low technical content has exceeded demand, and the market profit space is narrow. The medium and high-end molds with high technical content are still far from meeting the needs of national economic development. A large part depends on imports. For medium and high-end molds with high technical content, most mold factories purchase high-precision CNC, EDM, WEDM and other processing machine tools in order to obtain high manufacturing precision, but lack a comprehensive control technology and cannot obtain a an...

Problems solved by technology

However, it has not made further optimization in the prototype design, 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 the mold cavity being processed. , inevitably, it takes a lot of energy and time to repeatedly try molds and modify product parameters and mold parameters, and it is impossible to achieve the effect of zero FIT mold
