Description
Technical Field
The invention relates to the technical field of melting cups, in particular to a universal melting cup for a die casting machine.
Background
Die casting is a metal casting process and is characterized in that high pressure is applied to molten metal by utilizing an inner cavity of a die. The mold is typically machined from a stronger alloy, a process somewhat similar to injection molding. Most die cast parts are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Depending on the type of die casting, either a cold chamber die casting machine or a hot chamber die casting machine may be used. The casting equipment and molds are expensive to manufacture, and therefore the die casting process is typically only used to mass produce a large number of products. It is relatively easy to manufacture die-cast parts, which typically require only four main steps, with a low incremental cost alone. Die casting is particularly suitable for manufacturing a large number of small and medium-sized castings, so die casting is the most widely used one of various casting processes. Compared with other casting technologies, the die-cast surface is smoother and has higher size consistency.
Inside traditional die-casting melting cup often need pour high temperature working liquid into die-casting melting cup body when using, when using for a long time, if the inside inner chamber of die-casting melting cup is untimely to be changed, will seriously influence foundry goods quality, general die-casting melting cup all is whole scrapping the change after using a period of time, and this kind of way cost is higher, inconvenient extensive using widely.
In addition, the injection punch is a key part for metal die casting production. The injection punch head is matched with the melting cup, the working principle of the injection punch head is similar to that of a push rod and a needle cylinder of an injector, and molten alloy liquid is pushed and extruded into the melting cup. The size clearance between the injection punch and the inner wall of the melting cup is small and is generally less than 0.05 mm. In the using process, the cylindrical surface of the injection punch is worn by two types, and the injection punch is scrapped when the wear amount of the injection punch is larger than the allowable clearance. At present, the injection head has a plurality of manufacturing processes, and the traditional production process is manufactured by nodular cast iron, so that the cost is low, but the service life is short; the injection head is subjected to surface treatment, such as laser alloying surface treatment, so that the service life is long, but the cost is high; the injection head is well matched with the die-casting cavity, so that the injection head is long in service life, but high in cost, beryllium is a highly toxic substance, and the production of the beryllium bronze pollutes the environment; the bimetal is used for manufacturing, so that the service life is long, but the processing technology is complex and the cost is high.
