[0010] Preferably, the axes of the first limiting hole and the second limiting hole are perpendicular to each other.

[0011] Preferably, the axial direction of the second limiting hole is parallel to the length direction of the pull rod.

[0012] Preferably, the first limiting block and the second limiting block are respectively provided with a first connecting post and a second connecting post on the side facing the pull rod. The pull rod is provided with an inclined groove and a positioning hole for the first connecting post and the second connecting post to be inserted. During assembly, the first connecting post can slide along the inclined groove, and the second limiting block can move together with the pull rod.

[0013] Preferably, the inclined groove slopes upward from left to right and extends along the length of the tie rod.

[0014] Preferably, the first pin slot and the second pin slot pass through the first guide groove and the second guide groove respectively, and respectively form the first limiting groove and the second limiting groove.

The male head molding cavity 11 has a first pin slot 12 and a second pin slot 13 corresponding to the first pin 31 and the second pin 32. The first pin 31 and the second pin 32 are respectively provided with a first limiting hole 311 and a second limiting hole 321. The locking assembly includes a pull rod 21 disposed on the other side of the strip body 10 and a locking mechanism. The first limiting block 22 and the second limiting block 23 are pulled by the pull rod 21. The first limiting block 22 has a first limiting post 222 corresponding to the first limiting hole 311 on the side facing the first pin 31, and the second limiting block 23 has a second limiting post 232 corresponding to the second limiting hole 321 on the side facing the second pin 32. In use, the pull rod 21 drives the first limiting block 22 and the second limiting block 23 to move, so that the first limiting post 222 and the second limiting post 232 are respectively inserted into the first limiting hole 311 and the second limiting hole 321, thereby limiting the first pin 31 and the second pin 32. By setting a locking component in the mold strip body, and setting a limiting hole for the pin to cooperate with the locking component, during injection molding, the pin is inserted into the pin slot, and the pull rod is moved to make the limiting post insert into the limiting hole of the pin, thereby locking the pin and ensuring that the pin does not move during the injection molding process, thus solving the problems of low plug yield and high production cost.

[0029] Specifically, the template body 10 is provided with a sliding groove 16 for the pull rod 21 to slide. The template body 10 is also provided with a first guide groove 14 and a second guide groove 15 corresponding to the first limiting block 22 and the second limiting block 23, respectively. The sliding groove 16 connects the first guide groove 14 and the second guide groove 15 in sequence. The first pin slot 12 and the second pin slot 13 pass through the first guide groove 14 and the second guide groove 15, respectively forming the first limiting groove 141 and the second limiting groove 151. During assembly, the plug 30 is inserted into the male head forming cavity 11, the first pin 31 and the second pin 32 pass through the first pin slot 12 and the second pin slot 13, and the first limiting hole 311 and the second limiting hole 321 are respectively placed in the first guide groove 14 and the second guide groove 15.

[0030] Specifically, the template body 10 has mounting plates 17 on opposite sides of the slide groove 16 along its length extension direction. The mounting plates 17 have through holes 171 for the pull rod 21 to pass through. It should be noted that the mounting plates 17 can be fixedly installed on the template body 10 by bolts or screws.

[0031] In another embodiment, the module body 10 is provided with a mounting seat on the side where the pull rod 21 is provided, and the mounting seat is provided with a limiting groove corresponding to the pull rod 21.

[0032] Specifically, the first limiting block 22 and the second limiting block 23 are respectively provided with a first connecting post 221 and a second connecting post 231 on the side facing the pull rod 21. The pull rod 21 is provided with an inclined groove 211 and a positioning hole 212 for the insertion of the first connecting post 221 and the second connecting post 231. The inclined groove 211 is inclined upward from left to right and extends along the length of the pull rod 21. During assembly, the first connecting post 221 can slide along the inclined groove 211, and the second limiting block 23 can move together with the pull rod 21. During assembly, the pull rod 21 is installed in the slide groove 16, the first limiting block 22 and the second limiting block 23 are located in the first guide groove 14 and the second guide groove 15 respectively, the first connecting post 221 is inserted into the inclined groove 211, and the second connecting post 231 is inserted into the positioning hole 212.

[0033] Specifically, the axial directions of the first limiting hole 311 and the second limiting hole 321 are perpendicular to each other, and the axial direction of the second limiting hole 321 is parallel to the length direction of the pull rod 21.

[0034] More specifically, in the unlocked state, the first limiting post 222 is away from the first limiting groove 141, and the second limiting post 232 is away from the second limiting groove 151; when locked, the pull rod 21 is moved, the first limiting block 22 moves towards the side closer to the first pin 31, and the second limiting block 23 moves towards the side closer to the second pin 32, and the first limiting post 222 and the second limiting post 232 are respectively inserted into the first limiting hole 311 and the second limiting hole 321 to complete the locking.

[0035] In summary, this utility model has the following beneficial effects: by setting a locking component in the body of the mold strip and setting a limiting hole for the pin to cooperate with the locking component, during injection molding, the pin is inserted into the pin slot, and the pull rod is moved to make the limiting post insert into the limiting hole of the pin, thereby locking the pin and ensuring that the pin does not move during the injection molding process, thus solving the problems of low plug yield and high production cost.
