The requirements for sand mold quality in mold casting mainly include the following aspects:
1. Precision and accuracy: the production of sand mold needs to ensure the accurate reproduction of the shape and size of the casting, to ensure the accuracy and quality of the casting. Therefore, the production of sand mold requires high precision, can accurately show the shape and size of the design requirements.
2. Surface quality: the surface quality of the sand mold directly affects the surface finish and accuracy of the final casting. Good surface quality of the sand mold can reduce the defects and defects of the casting, and improve the surface finish and appearance quality of the casting.
3. Strength and stability: the sand mold needs to bear the high temperature and pressure of metal in the process of pouring, so the strength and stability of the sand mold are very important. The high strength sand mold can resist metal erosion and impact, and keep the shape and size of the casting stable.
4. Fire resistance: sand mold needs to have good fire resistance, can maintain stable structure and performance at high temperature, without deformation, cracking or damage. Sand molds with strong fire resistance can ensure the quality and size of castings.
5. Adaptability and reusability: The materials made by sand mold need to have certain adaptability and can be applied to different types and sizes of castings. At the same time, the material of sand mold should also have a certain degree of reusability, can be used for many times, reduce costs and resource waste.
To sum up, the requirements for sand mold quality in sand casting mainly include precision and accuracy, surface quality, strength and stability, fire resistance, adaptability and reusability, etc. High quality sand mold can ensure the quality and production efficiency of castings, and improve the competitiveness and market position of enterprises.
