Casting process of diesel engine bearing seat

Abstract

The invention discloses a casting process of a diesel engine bearing seat. The casting process comprises the following steps: making a mold of the diesel engine bearing seat; preparing a manufacturing tool; forming a pouring gate, a dead head and an exhaust port in the mold; putting resin sand into the mold so as to model the resin sand; patching the modeled resin sand mold; brushing a coating at the surface of the resin sand mold; arranging and closing the resin sand mold; lifting the resin sand mold; putting a pouring cup at the pouring gate of the mold; putting a dead head cup at the dead head; pouring molten iron into a cavity of the resin sand mold by a crane ladle for pouring; and introducing water into the cavity to cool the resin sand mold after the pouring, wherein the water temperature is controlled not to exceed 80 DEG C through controlling the flow of cooling water. The casting process of the diesel engine bearing seat, disclosed by the invention, has the advantages of capability of improving cast quality, short production period and low production cost.

Description

Technical field: [0001] The invention relates to a casting process of a diesel engine bearing seat. Background technique: [0002] At present, when the diesel engine bearing seat is cast, the hole during pouring is in a horizontal state. In order to prevent the sand core from being unable to resist the high temperature of the high-temperature molten iron and the buoyancy of the double action, resulting in softening of the core bone and bending of the sand core, a core support has to be used. The integrity of the casting is damaged, reducing the quality of the casting. Invention content: [0003] The purpose of the present invention is to overcome the above disadvantages and provide a casting process for diesel engine bearing seats with improved casting quality, short production cycle and low production cost. [0004] The purpose of the present invention is achieved through the following technical solutions: a casting process for a diesel engine bearing seat, comprising th...
