At present, the application of mold involves every product (such as automobile, aerospace, daily necessities, electrical communication, medical equipment, etc.). As long as it is a large number of products, mold production will be applied, and the mold base is an inseparable part of the mold. At present, the precision requirements of the formwork will be determined according to the product requirements according to different levels, and the appropriate supply will be provided to meet the different needs of various customers.
The mold base is a semi-finished product of the mold, which is composed of various steel plate fitting parts, and can be said to be the skeleton of the whole mold. Since the mold formwork is basically at a relatively high temperature during use, the formwork must have a certain high temperature resistance and can withstand a certain pressure.
The processing involved in the mold base and the mold is very different. The mold manufacturer will choose to order the mold base from the mold base manufacturer, and take advantage of the production advantages of both sides to improve the overall production quality and efficiency. The steel used in the mold base will also be used. There are strict requirements to ensure the overall performance of the formwork.
1. The steel used in the mold base must be properly polished to make its surface smoother. The impurities in the steel should not be too much. There will be no pitting and orange peel in the polishing. Wait.
2. The cutting process will have a long-term influence on the performance of the mold formwork. In order to make the cutting tool can be used for a long time, to ensure good cutting performance and reduce roughness, it is necessary to use suitable steel in the mold formwork.
3. The mold base needs to be heat treated to increase its hardness and ensure a thicker stiffness. Because the mold is subjected to large pressure and friction during use, it is necessary to ensure the accuracy and stability of the mold shape and size to ensure that the mold frame can be used for a longer period of time. The impact on the wear resistance of the mold formwork is greatly affected by the chemical composition of the steel and the hardness of the heat treatment. Therefore, when the hardness of the mold form is increased, it will have better wear resistance. .
