What Is Casting Mold?
Casting mold means that in order to obtain the structural shape of the part, the structural shape of the part is made in advance with other easily formed materials, and then the mold is placed in the sand mold, so that a cavity having the same structural size as the part is formed in the sand type. A fluid liquid is then poured into the cavity, and the liquid is cooled and solidified to form a part identical to the shape of the mold. Casting molds are an important part of the casting process.
The casting mold refers to a mold used to form a casting in a casting forming process. The casting mold is matched with the casting process, mainly including gravity casting mold, high pressure casting mold (die casting mold), low pressure casting mold, and extrusion casting mold. Casting mold is one of the most important process equipment in casting production, which has a great influence on the quality of castings. The improvement of casting mold technology will be of great significance to improve the quality of castings, develop new castings and improve the near-net processing level. The advancement of casting mold technology will provide more precise, complex and high-quality castings for the pillar industries of the automobile, electric power, shipbuilding, rail transit, aerospace and other industries.
In order to shorten the molding cycle and improve the market competitiveness, mold companies are adopting more and more high-speed cutting technology. HSM is generally used for large and medium-sized mold processing, such as automotive cover molds, die-casting molds, large plastic molds and other surface machining, and its surface machining accuracy can reach 0.01mm. The use of CNC high-speed milling technology in production can greatly shorten the molding time. The mold surface after high-speed milling and finishing can be used only with a little polishing, saving a lot of grinding and polishing time. The addition of CNC high-speed milling machines is one of the key points of equipment investment in mold enterprises.
Electro discharge machining (EDM) is an indispensable process in the manufacture of foundry molds. EDM is still an effective solution for the processing of deep and small cavities after quenching.
Users demand shorter and shorter mold delivery times and lower mold prices. In order to ensure on-time delivery, effective management and control of costs has become a major factor in the survival and development of mold companies. The use of advanced governance information systems to achieve integrated governance, for mold companies, especially large-scale mold enterprises, has become an extremely important task.
