Wherein, when the film is combined, the first mold body 10, the second mold body 20 and the row position assembly 30 jointly enclose a forming cavity, and the glue material is formed in the forming cavity.

[0036] Please refer to Figures 1 to 4The delay assembly 40 comprises a trigger 1, a clamping piece 2 and an elastic piece 3. The trigger 1 is arranged on the first mold body 10 and can move to the first position or the second position along with the first mold body 10. The clamping piece 2 is rotatably connected to the second mold body 20 and has oppositely arranged clamping end 21 and controlled end 22. One end of the elastic piece 3 is connected to the controlled end 22 and the other end is connected to the second mold body 20. The elastic piece 3 is arranged on one side of the controlled end 22. When the trigger 1 is in the first position, the other side of the controlled end 22 abuts against the trigger 1, the elastic piece 3 is in a compressed state, and the clamping end 21 is clamped and matched with the row position assembly 30. When the trigger 1 is in the second position, the controlled end 22 rotates to be separated from the row position assembly 30 under the restoring force provided by the elastic piece 3.

[0037] In the process of mold opening, first, the first mold body 10 moves away from the second mold body 20 under the abutting force, and the first mold body 10 and the second mold body 20 are separated to complete the parting. The first mold body 10 continues to move until the trigger 1 is in the second position. At this time, the clamping piece 2 rotates to be separated from the row position assembly 30 under the restoring force provided by the elastic piece 3, and the row position assembly 30 can be separated from the second mold body 20 to complete the parting. When the mold is closed, the first mold body 10 and the second mold body 20 are attached. At this time, the trigger 1 is in the first position, one side of the clamping piece 2 elastically abuts against the second mold body 20 through the elastic piece 3, and the other side abuts against the trigger 1, so that the clamping piece 2 cannot rotate relative to the second mold body 20, and the clamping piece 2 and the row position assembly 30 remain in the clamped and matched state.

[0038] By arranging the trigger 1 that can move to the first position or the second position along with the first mold body 10, the clamping piece 2 and the row position assembly 30 are controlled to remain in the clamped and matched state or rotate to be separated from the row position assembly 30, and then the row position assembly 30 and the second mold body 20 are controlled to be fixed or separated, so that the row position assembly 30 and the second mold body 20 can be separated only after the first mold body 10 moves a certain distance (i.e. after a certain time), the parting of the first mold body 10 and the second mold body 20 is before the parting of the row position assembly 30 and the second mold body 20, the parting order is controlled, the delayed mold opening is realized, and the injection molding product is prevented from sticking to the mold or deforming. Moreover, when the mold is closed, the clamping piece 2 and the row position assembly 30 remain in the clamped and matched state, the connection firmness of the row position assembly 30 and the second mold body 20 can be improved, and the injection molding product is prevented from deforming due to the movement of the row position assembly 30.

[0039] It should be noted that when the first mold body 10 and the second mold body 20 are parted, the row position assembly 30 is first fixed with the second mold body 20 under the action of the delay assembly 40, so as to facilitate the first mold body 10 to break the gate tail; after a certain time, the clamping piece 2 is separated from the row position assembly 30, at this time, the row position assembly 30 and the second mold body 20 can be parted, and the injection molding product and the second mold body 20 are separated.
