Specifically, as shown in fig. 1 to 4, the side pressing actuator 9 is vertically disposed, an upper end of the side pressing actuator 9 is fixedly connected to an upper die body of the automobile tailgate press-fit die, the upper die body is disposed to be linearly movable in the vertical direction, and the upper die body drives the side pressing actuator 9 to synchronously perform linear movement. The slider 1 is the slope setting, and gyro wheel 6 is installed in the upper end of slider 1 through round pin axle 3, and the lower extreme at slider 1 is fixed mounting to the pressure core insert 12, has the contained angle and this contained angle is the acute angle between the length direction of slider 1 and the vertical direction. The base 8 plays the guide effect to slider 1, sets up the baffle 15 that contacts with the internal face of base 8 on the slider 1, baffle 15 and slider 1 fixed connection, and base 8 has the hole of dodging that lets slider 1 pass, and baffle 15 contacts with the internal face in the hole of dodging. Base 8 is connected with uide pin 2, and uide pin 2 is vertical setting, and the upper end and the pressure core of uide pin 2 are connected, and uide pin 2 plays the guide effect to base 8, and base 8 can carry out rectilinear movement for the pressure core along vertical direction. The pressure core is located the below of last mould body, and the pressure core passes through nitrogen gas spring and last mould body coupling.

As shown in fig. 1 and 2, in the present embodiment, the elastic element 7 is a tension spring, one end of the elastic element 7 is connected to the slider 1, and the other end of the elastic element 7 is connected to the base 8. The elastic elements 7 are provided in plurality, all the elastic elements 7 being distributed on opposite sides of the base 8. The elastic element 7 is obliquely arranged, the length direction of the elastic element 7 is parallel to the length direction of the sliding block 1, and the elastic element 7 applies upward pulling force to the sliding block 1.

As shown in fig. 1 and 2, in the present embodiment, four elastic members 7 are provided, two elastic members 7 are provided on both sides of the base 8,

as shown in fig. 1 to 4, the side pressing driver 9 has a driving surface 10 and a holding surface 11, which are in contact with the outer circumferential surface of the roller 6, the outer circumferential surface of the roller 6 is a cylindrical surface, the axis of the roller 6 is a horizontal line, the driving surface 10 is an inclined plane, an included angle is formed between the length direction of the driving surface 10 and the length direction of the slider 1 and is smaller than 180 degrees, the holding surface 11 is a vertically arranged plane, the holding surface 11 is parallel to the axis of the roller 6, the driving surface 10 is located below the holding surface 11, and the upper end of the driving surface 10 is connected with the lower end of the holding surface 11.
