In the injection molding process, the injection mold base plays a crucial role. It is the basic support of the whole injection mold, and its precision requirements directly affect the quality of injection products.

The accuracy of the injection mold base is first reflected in the dimensional accuracy. A high precision injection mold base must have strict dimensional tolerance control. If the size of the base is not accurate, it will lead to problems in the assembly of the entire mold. For example, when the length, width or height of the base is deviated, the various parts of the mold may not be accurately installed in place, thus affecting the closing accuracy of the mold. In the process of injection molding, the closing accuracy of the mold is directly related to the dimensional accuracy of the injection molding product. If the mold is not tightly closed, it will lead to defects such as flash and burr in the injection molding product, which seriously affects the appearance quality of the product. Therefore, the high precision injection mold base can ensure the accurate assembly of the mold, thus ensuring the dimensional accuracy of the injection product.

Secondly, the flatness of the injection mold base is also an important aspect of the accuracy requirements. A flat base ensures that all parts of the mold are on the same plane, thus ensuring an even distribution of injection pressure. If the flatness of the base is not enough, it will lead to uneven force in the injection molding process, which will cause uneven thickness and deformation of the injection molding product. For example, in the production of thin-walled injection molded products, the flatness of the base is required to be higher. Because the wall thickness of thin-walled products is very thin, any uneven force may cause the product to deform or break. Therefore, the high-precision injection mold base can provide stable support and ensure the uniform distribution of injection pressure, thereby improving the quality of injection products.
