Embodiment 1

[0028] Embodiment 1 A water-cooled middle shell

[0029] Such as figure 2 As shown, the present invention provides a water-cooled intermediate shell, including an intermediate shell casting 1, a sprue 2, a runner 3, an inner sprue 4, a riser 5, an air collecting bag 6, an outer sand shell 7, and an oil chamber core 8, water cavity core 9;

[0030] The sprue 2 is arranged at the center of the template and is perpendicular to the ground, and one sprue 2 is provided.

[0031] The runner 3 is arranged symmetrically on both sides of the sprue 1 and parallel to the ground,

[0032] The sprue 2 is connected to the runner 3, and the runner 3 is connected with a plurality of inrunners 4, and the inrunner 4 is connected to the riser 5, and the riser 5 is connected to two intermediate shell castings 1. The riser 5 and the two intermediate shell castings 1 are placed in the outer sand shell 7, and two air collection bags 6 are arranged on the top of the outer sand shell 7.

Embodiment 2

[0040] Embodiment 2 Casting process of a water-cooled middle shell

[0041] The invention provides a casting process for a water-cooled turbine shell, comprising the following steps:

[0042] Step S1: setting the sprue 2 at the center of the template and perpendicular to the ground;

[0043] Step S2: The runner 3 is arranged symmetrically on both sides of the sprue 2 and parallel to the ground, and the sprue 2 is connected to the runner 3;

[0044] Step S3: the runner 3 is connected with a plurality of ingates 4, and the ingates 4 are connected to the riser 5;

[0045] Step S4: The riser 5 connects the two middle shell castings 1, and the riser 5 and the two middle shell castings 1 are placed in the outer sand shell 7;

[0046] Step S5: Inject molten iron from the sprue 2 during pouring. The molten iron flows through the runner 3 and enters the cavity of the riser 5 through the inrunner 4. The molten iron in the riser 5 enters the two intermediate The cavity of the shell ca...

Abstract

The invention provides a water-cooled middle shell. A water cavity is formed in the middle shell, the water-cooled middle shell comprises a middle shell casting, straight of runners, cross of runners,inner of runners , risers, gas collecting bags and an outer sand shell; the straight of runners are arranged at the center position and is perpendicular to the ground, the cross of runners are symmetrically distributed on the two sides of the straight of runners and are parallel to the ground, wherein the straight of runners are connected with the cross of runners, the straight of runners are connected with a plurality of inner of runners , the inner of runners are connected with the risers, the risers are connected with two middle shell castings, the risers and the two middle shell castingsare placed in the outer sand shell, two gas collecting bags are arranged at the top of the outer sand shell. The water-cooled middle shell provides a casting process of the water-cooled middle shell.According to the water-cooled middle shell, the problem that the proportion of the water-cooled intermediate shell is relatively high can be solved, and the casting cost of the casting is effectivelyreduced.

Description

technical field [0001] The invention discloses a water-cooled intermediate shell and its casting process, 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 working principle of the turbocharger is that the exhaust gas from the engine drives the turbine to rotate, and the turbine drives the coaxial impeller to rotate to compress the air. The rotor shaft connecting the turbine and the impeller is installed in the middle casing through the floating bearing. The speed of the turbocharger is generally high, especially the speed of the turbocharger of the gasoline engine can reach hundreds of thousands of revolutions per minute, so the heat dissipation of the middle casing The performa...
