Electric power equipment metal mold casting combined mold

Abstract

The electric power equipment metal mold casting combined mold is characterized in that mold column assemblies are provided with movable interconnection mechanisms, the mold column assemblies can be directly and movably connected, and nut columns are arranged at the top ends of the mold column assemblies; the bolt is screwed into the screw hole of the positioning plate, penetrates out of the screw hole and then is screwed into the nut column of the die column assembly, and when the bolt is screwed to the bottom, the thin shaft end at the root of the bolt is embedded into the screw hole, so that the bolt is positioned and the telescopic length of the die column assembly is positioned; the combined mold core frameworks in various shapes can be formed through various connection and combination modes of the mold column assemblies, and the mold frame is fixed after being nested in the combined mold core frameworks; the adjustable interconnection mechanism is nested in the movable interconnection mechanism at the outer end of the combined mold core framework, the mold transverse plate, the mold longitudinal plate and the mold special-shaped plate are movably connected with the adjustable interconnection mechanism, and the lower mold plate and the upper mold plate are connected with through holes of the mold column assembly. The fine difference between the combined metal mold casting mold and an ideal casting model can be compensated by nesting the lining plate of the mold plate, so that the advantage that the lining plate is easy to process can be fully utilized, and a complete combined mold core with a complex shape or a precise structure can be formed after finishing.

Description

technical field [0001] The invention relates to a metal mold for casting. Background technique [0002] Metal mold casting, also known as hard mold casting, is a widely used casting form. Non-ferrous alloy castings such as bronze, brass, and aluminum can be obtained by metal mold casting. Metal mold casting is a casting method in which liquid metal is first poured into a metal mold, then kept for an appropriate time, and finally the mold is opened to take out the casting after the metal solidifies to obtain a casting. [0003] Because the castings produced by metal mold casting, first, their mechanical properties are higher than those of sand castings. For the same alloy, the tensile strength can be increased by 25% on average, the yield strength can be increased by about 20% on average, and its corrosion resistance and hardness are also significantly improved. Second, the precision and surface finish of castings are higher than those of sand castings, and the quality and d...
