The quality of injection molds can be evaluated in the following aspects:

The stability and conformity of the size and size of the injection molded product, the smoothness and appearance of the product surface, the utilization rate of plastic raw materials, etc.;

The life of the injection mold: on the premise of ensuring the quality of the product, the number of cycles that the mold can use can also be called the number of products produced;

The ease of use of the mold: whether it is the most convenient to use, whether it is easy to demould, the production assistance time (waiting time) is as short as possible; and the cost of mold maintenance and the length of the mold maintenance cycle, etc.

The basic method to improve the quality of the mold is to consider the mold design, including the selection of mold materials, the usability and safety of the mold structure, the machinability of the mold parts and the convenience of mold maintenance. Considering the trade-off of comprehensive performance, the favorable factors are maximized.

The manufacturing process of the mold is also an important part of ensuring the quality of the mold. The processing method and machining accuracy in the mold manufacturing process will also affect the service life and ease of use of the mold. The accuracy of each part directly affects the overall assembly of the mold. Considering that the accuracy cannot reach 100%, it is necessary to improve the processing method of the parts and improve the technical level of the mold fitter in the mold grinding process to improve the mold parts processing. precision. The surface of the main forming parts of the mold is strengthened to improve the surface wear resistance of the mold parts, so as to better improve the quality of the mold.

The correct use and maintenance of the mold is also a major factor in improving the quality of the mold. For example, the installation and debugging method of the mold should be appropriate, in the case of a hot runner, the power supply wiring should be correct, the cooling water circuit should meet the design requirements, and the parameters of the injection molding machine, die-casting machine and press during the production of the mold should be consistent with the design requirements. etc. When using the mold correctly, it is also necessary to carry out regular maintenance on the mold. The guide posts, guide sleeves and other parts with relative movement of the mold should be frequently filled with lubricating oil. For forging molds, plastic molds, die-casting molds and other molds Lubricant or mold release agent should be sprayed on the surface of the formed parts before molding.

With the development of society, plastic products are more and more widely used in people's lives because of their safety and ease of use. At the same time, the appearance and internal quality requirements of plastic products are getting higher and higher, which determines the quality of plastic products. The key factor is the mold.
