Classification and application of casting molds for copper castings
There are many types of copper casting molds, which can be divided into: ①Metal molds according to the processing objects and processing technology. ② Processing non-metal and powder metallurgy molds. Including plastic molds (such as two-color molds, compression molds and extrusion molds, etc.), lost foam molds, rubber molds, and powder metallurgy molds. According to the structural characteristics, the mold can be divided into a flat punching mold and a cavity mold with space. Molds are generally single-piece, small batch production.
Aluminum castings should choose different copper castings casting molds according to the molding process. Molds are mainly divided into hardware molds, plastic molds, and their special molds.
Hardware molds are divided into: including stamping molds (such as blanking molds, bending molds, deep drawing molds, turning molds, shrinkage molds, undulating molds, bulging molds, plastic molds, etc.), forging molds (such as forging molds, upsetting molds, etc.) Forging die, etc.), extrusion die, extrusion die, die-casting die, forging die, etc.;
Non-metal molds are divided into: plastic molds and inorganic non-metal molds. According to the different materials of the mold itself, the mold can be divided into: sand mold, metal mold, vacuum mold, paraffin mold and so on. Among them, with the rapid development of polymer plastics, plastic molds are closely related to people's lives.
Plastic molds can generally be divided into: injection molding molds, extrusion molding molds, gas-assisted molding molds and so on.
In addition to the copper casting mold itself, it also needs a mold base, a mold base, and a mold core leading to the ejection device of the part. These parts are generally made into a universal type. Mold companies need to be bigger and more refined. They must determine product positioning and market positioning according to market demand, technology, capital, equipment and other conditions. These practices are especially worthy of learning and reference by small mold companies, and focus on gradually forming their own technical advantages and products. Advantage.
