The design of plastic molding mold has the characteristics of external constraints, complex and flexible structure, and strong experience and exploration. There are a lot of contents to analyze and discuss in mold design. If the design procedure is not reasonable or imperfect, the quality of mold design will be affected. Therefore, it is necessary to standardize and perfect the plastic mold design procedure. Generally, the design of plastic molding molds can be divided into three main stages.

(1) Discussion stage this stage is mainly the preparation stage of the design work, fully grasp the provided plastic parts and technical requirements, collect relevant technical information, explore technical measures to meet the requirements. Make necessary modification to plastic parts or technical requirements if necessary.

(2) the conceptual phase of this phase is according to the requirement of the previous stage have collected and the related technical data as well as the main part of special technical measures for mould design, and research in the mould design of major parts of how to suitable for the existing processing equipment and technology, and how to ensure the quality of mould processing, molding speed and improve the economic benefit.

(3) Design Stage This stage is mainly to put the finished idea into practice. Give the general assembly drawing and parts drawing of plastic molding mold, and put forward the standard parts to be used, standard parts to be modified and mold material plan.

The above is the three main stages of plastic molding mold, control each stage of each mold, is the follow-up mass production process to improve production efficiency, effective guarantee of qualified product output, but also to extend the service life of plastic molding mold is an important guarantee.
