Problems solved by technology
At present, there are many kinds of manufacturing processes for the injection head. The traditional production process is made of ductile iron, which is low in cost but short in life; the surface treatment of the injection head, such as laser alloying surface treatment, has a long service life but high cost; using beryllium Made of bronze, the injection head cooperates well with the die-casting cavity, and has a long service life, but the cost is high, and beryllium is a highly toxic substance, and the production of beryllium bronze pollutes the environment; made of bimetal, the service life is long, but the processing technology is complicated ,high cost

Abstract
The invention relates to a melting cup for a die-casting machine. The melting cup comprises a cup body and a core cylinder; a through hole is formed in the first end face of the cup body; an expansion hole is formed in the first end face of the cup body, the expansion hole and the through hole are coaxially formed, and the diameter of the expansion hole is larger than that of the through hole; the core cylinder is coaxially arranged in the expansion hole; coincident liquid inlets are formed in the first ends of the side walls of the cup body and the core cylinder; and the core cylinder is detachably connected with the cup body. According to the melting cup for the die-casting machine, the expansion hole is formed in the cup body, so that the core cylinder and the cup body are detachably arranged, when the liquid inlet is altered by alloy liquid to form a cavity, the melting cup can be continuously used by replacing the damaged core cylinder, the whole cup body does not need to be replaced, and cost is saved; and the melting cup is simple in structure and convenient to disassemble and assemble, and the replacement efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of melting cups, in particular to a melting cup used in a die-casting machine. Background technique [0002] Die casting is a metal casting process characterized by the application of high pressure to molten metal using the cavity of a mold. Molds are usually machined from stronger alloys, a process somewhat similar to injection molding. Most die castings are ferrous, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Depending on the type of die casting, a cold chamber die casting machine or a hot chamber die casting machine is used. The cost of casting equipment and molds is high, so the die casting process is generally only used for mass production of a large number of products. Manufacturing die-cast parts is relatively easy, generally requiring only four major steps with low incremental cost per item. Die casting is especially suitable for manufacturing a lar...
