Embodiment Construction

[0013] figure 1 and figure 2 Shown, a kind of manufacturing method of the pressure casting product that alloy liner is housed. The centrifugal pump casing mold with alloy lining is a hollow composite mold. The centrifugal pump casing hollow composite mold is composed of a centrifugal pump casing hollow sub-mold. The centrifugal pump casing hollow sub-mold is made of steel plate stamping and welding. It is stamped and welded with stainless steel plate, brass plate or aluminum alloy plate. Melt steel slag powder or glass powder with an oxyacetylene flame and spray it on the inner surface of the hollow sub-mold of the centrifugal pump casing that is in contact with molten steel during pressure casting, or use 'water glass' to blend steel slag powder or glass powder, and then coat it on the mold during pressure casting The inner surface of the hollow sub-mold of the centrifugal pump casing in contact with the molten steel, and then heated and melted with oxyacetylene flame to m...

Abstract

The invention discloses a manufacturing method of a pressure casting product with an alloy lining or inner container. The pressure casting product die provided with the alloy lining or the inner container is a hollow combined die, the hollow combined die is composed of hollow sub-dies made of steel plates, and the alloy lining is formed by stamping and welding a stainless steel plate, a brass plate or an aluminum alloy plate. The inner surface of the hollow sub-die is coated with molten steel slag powder or glass powder, and water is injected into the hollow sub-die and the alloy liner. The hollow sub-dies are assembled into the hollow combined die through screws and nuts, the hollow combined die is clamped on a metal conveying belt to be conveyed to the position below a molten steel pipe, the molten steel pipe moves in the direction to be in butt joint with a molten steel inlet of the hollow combined die, a spiral extrusion pump pressurizes molten steel, and then the molten steel enters the hollow combined die from the molten steel pipe through an opened ceramic valve. Water in the hollow sub-dies and the alloy inner container is heated into water vapor which is discharged from a safety valve to cool the alloy inner container, so that the alloy inner container is prevented from being melted and deformed; and meanwhile, a blank in the hollow combined die is cooled.

Description

Technical field: [0001] The invention relates to a manufacturing method of a pressure casting product equipped with an alloy inner liner or inner tank. Background technique: [0002] If the die-casting product is hollow, a sand core should be placed in the die-casting combination mold. To press the sand into a sand core, it is necessary to put some mineral oil in the sand, and the mineral oil will produce flammable gas during pressure casting, which will collapse the sand core and affect the quality of the pressure casting product. [0003] The lining of water pumps and valves used in food, medicine, and chemical production needs stainless steel or aluminum alloy to prevent rust. Medical oxygen should be clean, and oxygen cylinders made of stainless steel meet hygienic standards. Invention content: [0004] A method for manufacturing a pressure casting product with an alloy lining. The centrifugal pump casing mold with alloy lining is a hollow composite mold. The centri...
