What are the general steps of injection mold design?

The general steps of injection mold design cover the entire process from product analysis to mold manufacturing completion, each step is crucial to ensure the accuracy, efficiency and longevity of the final mold. Here are the detailed design steps:

1. Product analysis and design preparation

First of all, the product should be analyzed in detail, including its geometry, dimensional accuracy, material characteristics, etc. This stage also needs to consider the mass production requirements of the product to determine the type and structure of the mold. At the same time, the designer also needs to assess the potential design risks and manufacturing difficulties, and prepare for the subsequent design work.

2. Mold structure design

In the mold structure design stage, designers need to determine the overall layout of the mold, parting surface, flow channel system and other key elements according to the results of product analysis. This stage also requires detailed mechanical calculations to ensure the stability and reliability of the mold during injection molding. In addition, the die’s exhaust, cooling and ejection systems also need to be carefully designed to optimize production efficiency and product quality.

3, mold parts design

The design of mold parts includes core, cavity, slider, inclined top and other key parts. The shape, size and accuracy of these parts directly affect the molding quality of the product and the service life of the mold. Therefore, designers need to use appropriate design software and manufacturing technology to accurately complete the design of these parts according to the results of the mold structure design.

4, mold assembly drawing design

After the completion of the mold parts design, the designer needs to draw the mold assembly drawing to clarify the assembly relationship and movement trajectory between the parts. At this stage, the assembly accuracy of the mold also needs to be adjusted and optimized to ensure that the mold can achieve the expected use effect after assembly.

5. Mold manufacturing and debugging

Finally, according to the mold assembly drawing and related technical requirements, the mold manufacturing and debugging. In the manufacturing process, it is necessary to strictly control the machining accuracy and assembly quality of the parts. In the commissioning phase, the mold needs to be comprehensively inspected and tested to ensure that it can meet the production requirements of the product.

In summary, the general steps of injection mold design cover the entire process from product analysis to mold manufacturing completion. Each step requires the designer to have a wealth of expertise and practical experience to ensure the quality and performance of the final mold.
