DETAILED DESCRIPTION

[0021] Below, we combine the turbine supercharger volute casting mould of the utility model described in the further explanation of the drawings.

[0022] It should be explained that, all directionality instructions such as upper, lower, left, right, front, back in the embodiment of the application only are used to explain the relative position relationship, movement condition etc. between each component in a certain specific posture, such as the drawing shows, if the specific posture changes, then the directionality instruction also changes accordingly.

[0023] Referring to the drawingsFigures 1-7 The turbine supercharger volute casting mold shown in the embodiment comprises a bottom mold 1, a lower mold 2 installed on the bottom mold 1, an upper mold 3 installed on the lower mold 2, and a sand core 4 installed on the bottom mold 1, characterized in that a removable insert 5 for realizing casting of different specifications of flanges on the volute is installed in the lower mold 2, and a locking piece 6 for locking the insert 5 is installed in the lower mold 2 through threads; a plug 601 matched with a cavity in the lower mold 2 is removably installed on the locking piece 6 through threads; the locking piece 6 can be a screw or a screw rod; by installing the plug 601 into the lower mold 2 through the locking piece 6, the corresponding specification of flange on the volute can be cast according to the size of the cavity of the lower mold 2; by installing the insert 5 into the cavity of the lower mold 2, different specifications of flanges on the volute can be cast, so that the same mold can be used to cast turbine supercharger volutes of different specifications, thereby reducing the cost of production and improving the efficiency of production; by installing the insert 5 into the lower mold 2 through the locking piece 6, the insert 5 can be removed by only removing the locking piece 6 from the lower mold 2, thereby facilitating the installation and removal of the insert 5.
