And the runner preset line generating module is used for generating a runner preset line according to the characteristic parameters of the die. As shown in fig. 3, the flow channel preset line 8 includes a cooling part preset line 9 and a connecting part preset line 10; the cooling portion preset line 9 is at least one curve extending in the working surface area 6; the connecting part preset line 10 extends in the cooling flow passage reserved space 7 in the die shell 3 and is respectively connected to the center point of each flow passage inlet and outlet; the cooling part preset line 9 is connected to the connecting part preset line 10 through an end point 11. In some embodiments, as shown in fig. 3A and 3D, the cooling portion preset line 9 is a curve extending in the working surface area 6, and two end points 11 are respectively connected to two connecting portion preset lines 10; in other embodiments, the cooling portion preset lines 9 are a plurality of curves extending in the working surface area 6, and each cooling portion preset line 9 is connected to a corresponding connecting portion preset line 10, as shown in fig. 3C; or the plurality of preset cooling part lines 9 cross the same end point and share one preset connecting part line 10, as shown in fig. 3B.
