Description

Technical Field

[0001] The utility model relates to the technical field of mold equipment, in particular to a hard alloy mold which is easy to assemble and disassemble. Background Art

[0002] Cemented carbide is an alloy material made from a hard compound of a refractory metal and a binder metal through a powder metallurgy process. It exhibits excellent properties such as high hardness, wear resistance, strength and toughness, heat resistance, and corrosion resistance. Cemented carbide is widely used as a tool material for turning tools, milling cutters, planers, drills, and boring tools. It is used for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone, and ordinary steel. It can also be used to cut difficult-to-machine materials such as heat-resistant steel, stainless steel, high-manganese steel, and tool steel. When cemented carbide is processed into alloy components such as turning tools and milling cutters, it is typically produced through injection molding. The mold typically consists of two separate and removable parts: an upper mold and a lower mold. Separating the mold allows the part to be removed, while closing the mold allows the blank to be injected into the mold cavity.
