The bidirectional core-pulling structure 41 is arranged so that when the die is opened, the bidirectional core-pulling structure 41 can firstly pull the first core-pulling block 412 out of the buckling position 91, and a straight-top space is reserved for the buckling position 91, so that the straight-top structure 42 can conveniently eject the air curtain interior trim 9. By adopting the bidirectional core-pulling structure 41, the left and right air curtain interior trim panels 9 can be pulled in one step, the die volume is reduced, meanwhile, the I-shaped sliding is adopted to ensure the accurate movement of the first core-pulling block 412 in the die opening and closing process, and the stable and reliable ejection process and the accuracy of forming the air curtain interior trim panels 9 are ensured.
Referring to fig. 3 and 5, the upper die 2, the lower die 3 and the ejector mechanism 4 together form a casting cavity 5, the upper die 2 comprises an injection port 21 and a runner 6 communicated with the injection port 21, the runner 6 is communicated with the injection port 21 and the cavity 5, the injection port 21 is connected with an external injection molding machine, and an air curtain interior decoration plate 9 is formed by injection molding into the cavity 5 through the runner 6.
