[0015] In the description of the utility model, it is necessary to explain that for the orientation words, such as the term "center", "transverse (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate the orientation and positional relationship based on the orientation or positional relationship shown in the drawing, which is only for the convenience of describing the utility model and simplifying the description, and is not indicative or implicit of the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, and can not be understood as limiting the specific protection scope of the utility model.

[0016] In addition, if the terms "first", "second" are only used for the purpose of description, and can not be understood as indicating or implying relative importance or implicitly indicating the number of technical features. Therefore, the "first", "second" features can be explicitly or implicitly included one or more features, and in the description of the utility model, the meaning of "several", "several" is two or more than two, unless otherwise explicitly specified.

[0017] ​Reference is made to Figures 1 to 4 The utility model further illustrates.

[0018] A vehicle subframe die, including upper die 1 and lower die 2, be provided with mould cavity 3 on upper die 1 and lower die 2, be provided with several cooling runner 4 on upper die 1 and lower die 2, the several cooling runner 4 is distributed around mould cavity 3 periphery, be connected with liquid outlet runner 5 and liquid inlet runner 6 on cooling runner 4, liquid outlet runner 5 is connected with the liquid discharge pipe 7 of outside, liquid inlet runner 6 is connected with the liquid supply pipe 8 of outside, liquid outlet runner 5 and liquid inlet runner 6 are close to each other, liquid outlet runner 5 is located the side of cooling liquid to on cooling runner 4, liquid inlet runner 6 is located the side of cooling liquid to.
