Description

Technical Field

[0002] Casting (casting) is a method of melting gold and silver into a liquid state and casting it into molds to form objects. It is one of the earliest gold and silver processing methods. Casting involves pouring the mixed slurry into the engine housing, which solidifies to form an engine charge that meets the design requirements. The crankshaft connecting rod mechanism is a key component in automobile engines. Its function is to convert the expansion pressure of the gas generated by fuel combustion acting on the top of the piston into torque that rotates the crankshaft, thereby continuously outputting power. When casting some crankshaft connecting rods, the molten material is poured into a manually fixed mold for casting and forming. The molding mold is then manually separated and the formed crankshaft connecting rod is removed, which greatly increases the difficulty of manual operation. Utility Model Content
