[0034] The shape of the ingate 7 is a sheet shape...

Embodiment 2

[0036] Casting process of embodiment 2 water-cooled turbine casing

[0037] The invention provides a casting process for a water-cooled turbine shell, comprising the following steps:

[0038] Step S1: placing the sprue 5 on one side of the casing 1;

[0039] Step S2: placing the runner 6 in a ring around the outside of the housing 1 and connecting it with the sprue 5;

[0040] Step S3, two inrunners 7 are opened on the runner 6, and the inrunners 7 are connected with the housing 1;

[0041] Step S4, placing a semicircular fan-shaped cold iron 8 in the inner hole of the housing 1;

[0042] Step S5, pouring molten iron from the sprue 5 during pouring, the molten iron flows through the runner 6 and then enters the cavity of the housing 1 through the two inrunners 7, and forms a turbine casing casting after cooling.

[0043] In the present invention, the molten iron is poured from the sprue 5, and the part of the inner hole that is prone to shrinkage is quenched by the cold iro...

Abstract

The invention discloses a water cooling turbine shell. The water cooling turbine shell comprises a shell body which is internally provided with a water cavity. The water cooling turbine shell also comprises a straight pouring channel, a transverse pouring channel and inner pouring channels. The straight pouring channel is arranged on one side of the shell body and is perpendicular to ground. The transverse pouring channel is arranged on one side of the shell body and is parallel to the ground. The straight pouring channel is connected with the transverse pouring channel and the transverse pouring channel is connected with the inner pouring channels. The number of the inner pouring channel is two. The inner pouring channels are connected with the shell body. A chill block is arranged in aninner hole of the shell body. The invention also provides a casting technology of the water cooling turbine shell. According to the water cooling turbine shell and the casting technology thereof, theproblem of low production rate of the water cooling turbine shell is solved; casting cost is lowered; the effect of sequential solidification from interior to exterior is achieved; casting defects arenot caused in a casting piece; a feeding head with heavy weight is omitted; the production rate is high; and production cost of the casting pieces is effectively lowered.

Description

technical field [0001] The invention discloses a water-cooled turbine casing and a casting process thereof, and relates to the technical field of turbochargers. Background technique [0002] The turbocharger is one of the most important parts of the engine at present. Under the condition of a certain engine displacement, it can effectively increase the output power of the engine, and has achieved the effect of saving energy and reducing consumption. The power source of the turbocharger is the high-temperature and high-pressure exhaust gas discharged from the engine. The exhaust gas enters the turbine housing of the turbocharger to drive the turbine to rotate. Therefore, the turbine housing needs a certain high temperature resistance and good heat dissipation performance. When the working environment is special Or when the heat dissipation capability is required to be high, the turbine casing is generally designed as a water-cooled turbine casing. Compared with the ordinary a...
