Gravity casting machine is one of the basic technologies of modern machinery manufacturing technology. Gravity casting machine uses casting technology to melt metal into a liquid that meets certain requirements and pour it into a mold. After cooling, solidification and cleaning, the predetermined shape can be obtained , scale and function of foundry machinery.
At present, bisphenol A epoxy resin is widely used in the world. Unsaturated polyester resin is also used in Europe and the United States. Other resins can also be used, but the application and process control are different from bisphenol A epoxy resin. For different structures , the use of additives for resin and curing systems, different grades of fillers and desiccants for aggregate drying, or the necessary process for the proper mixing of resins and curing agents. plan.
According to the function of ore castings, reasonable structural design is carried out to ensure that the advantages of ore castings are fully utilized. Mold design, including the manufacturing formula of steel molds, wooden molds and other materials, as well as the use method, ensure the surface lubrication of ore castings, and the internal strengthening is beautiful. , greatly improving the rigidity of ore castings.
Due to the complexity of castings, aluminum alloy casting molds are also different. Even for the same part, the casting process used is different, and the shell method is generally different, but in any case, aluminum alloy profile force casting molds may have their relevance.
1. Analysis of Influencing Factors
During the production process of the casting machine, the temperature will have a great influence. If the temperature is too high, it will affect the quality of the equipment, and the surface of the equipment will appear broken, air bubbles, shrinkage cavities and other phenomena, which will seriously affect the processing accuracy and use effect of the equipment.
2, The cause analysis of the factors
There are many factors that affect the production temperature of the casting machine. Due to the temperature of the steel itself and the high surface temperature of the steel at the beginning of production, the production temperature of the casting rises rapidly, which affects the normal production of the casting machine and endangers the quality of production. The second is about the production of materials , Due to the different manufacturers of casting machine materials, the quality of the materials is difficult to control, resulting in unstable temperature control of the casting machine during the production process.
In order to solve the above problems, it is necessary to select qualified materials as the production materials of the pouring machine as far as possible, and control the temperature well.
