With the development of science and technology and the vigorous development of foundry industry, different foundry methods have different mold preparation contents. Taking the most widely used sand casting as an example, mold preparation includes two major tasks: molding material preparation, molding and core making. In sand casting, all kinds of raw materials used for molding and core making, such as casting raw sand, molding sand binder and other auxiliary materials, as well as molding sand, core sand and coating prepared from them, are collectively referred to as molding materials. The task of preparing molding materials is to select appropriate raw sand, binder and auxiliary materials according to the requirements of castings and the properties of metals, and then mix them into tools according to a certain proportion Molding sand and core sand with certain properties. The commonly used sand mixing equipment includes wheel mixer, counter current mixer and continuous mixer. The latter is specially designed for mixing chemical self hardening sand, which is continuously mixed and has high mixing speed.
Molding and core making are carried out on the basis of determining the molding method and preparing the molding materials according to the casting process requirements. The accuracy of castings and the economic effect of the whole production process mainly depend on this process. In many modern casting workshops, the molding and core making are mechanized or automated. The commonly used sand molding and core making equipment includes high, medium and low pressure molding machine, air impact molding machine, non box injection molding machine, cold box core making machine, hot box core making machine, film coated sand core making machine, etc.
After the casting is taken out from the casting mould cooled by pouring, there are gates, risers, metal burrs and draping seams. Sand is also adhered to the casting of sand casting, so it must be cleaned. The equipment for this kind of work includes polishing machine, shot blasting machine, pouring and riser cutting machine, etc. Sand casting cleaning is a process with poor working conditions, so when choosing the molding method, we should try to create convenient conditions for sand cleaning. Some castings need to be treated after casting due to special requirements, such as heat treatment, reshaping, antirust treatment, rough machining, etc.
Casting process
The casting process can be divided into three basic parts: the preparation of casting metal, the preparation of casting mold and the treatment of casting. Cast metal refers to the metal material used for casting in casting production. It is an alloy composed of a metal element as the main component and other metal or non-metal elements. It is commonly known as cast alloy, mainly including cast iron, cast steel and cast non-ferrous alloy.
After the casting is taken out from the casting mold cooled by pouring, there are gates, risers and metal burrs. The casting of sand casting also adheres to sand, so it must go through the cleaning process. The equipment for this kind of work includes shot blasting machine, gate riser cutting machine, etc. Sand casting cleaning is a process with poor working conditions, so when choosing the molding method, we should try to create convenient conditions for sand cleaning. Some castings need to be treated after casting due to special requirements, such as heat treatment, reshaping, antirust treatment, rough machining, etc.
