Furthermore, a lap joint channel communicated with the middle vertical pouring gate is obliquely and upwards arranged; the cross section of the lap joint channel communicated with the middle vertical pouring gate and the cross section of the lap joint channel communicated with the top pouring gate are smaller than that of the lap joint channel communicated with the first-stage vertical pouring gate.
Particularly, the middle pouring gate forms a plurality of layers of stepped pouring gates from bottom to top, and one sides of the plurality of layers of stepped pouring gates are respectively connected with the casting cavity through lap passages; the lap joint channel communicated with the multilayer stepped pouring channel is provided with an upward inclined or downward inclined extension part; the upward inclined extending part is communicated with a casting cavity, and the downward inclined extending part extends into a lap joint channel communicated with the primary vertical pouring gate.
In conclusion, the invention has the following beneficial effects: the casting mold for casting the automobile clutch pressure plate, which is disclosed by the invention, aims at the problem that the existing casting mold has a serious shrinkage cavity compensation defect at the lower part of a riser, and is specifically characterized in that:
(1) the invention improves the feeding performance of the riser, eliminates the feeding defect, increases the section of the bottom pouring gate by using step type pouring, shortens the length and the section of the feeding pouring gate, shortens the mold filling time and reduces the temperature difference in the mold filling process;
(2) according to the invention, the lapping channel of the middle pouring channel is obliquely and upwards arranged, so that the impact on the mould wall caused by high flow speed due to the fact that molten iron directly flows into the mould cavity from the middle pouring channel is reduced, and meanwhile, when the first pouring channel pours, two liquid flows form circulation and the phenomenon that metal is also wrapped by gas occurs;
(3) the middle pouring channel of the invention forms a plurality of layers of ladder-shaped pouring channels from bottom to top, the horizontal lapping channel and the lapping channel which inclines upwards enable the mold filling process to be stable, the impact of molten metal on the mold wall is small, when the molten iron mold filling contacts with a riser, the molten iron flowing from the top pouring channel can not be lifted to pour, and the molten metal can splash.
