In this embodiment, the receiving groove 112 extends along the vertical direction, and the receiving groove 112 is adapted to the cavity 12. The cavity 12 can slide up and down in the receiving groove 112, and during the mold closing process, the cavity 12 slides down to gradually approach the core 22. Specifically, a telescopic cylinder may be disposed in the groove of the receiving groove 112, and an output end of the telescopic cylinder is connected to the cavity 12 to lift the cavity 12. In other embodiments, the sliding and locking of the cavity insert 12 can be realized by other sliding stoppers. It can be understood that during the mold clamping process, the cavity 12 moves downward in the receiving groove 112, i.e. toward the core 22, so that the press-fit surface 121 presses the bearing surface 221 of the core 22.

Referring to fig. 6 and 7, in an embodiment, the bottom wall of the receiving groove 112 is provided with a through hole 113 penetrating through the front mold plate 11, the cavity 12 is provided with an inclined hole 122 corresponding to the through hole 113, the movable mold assembly 1 further includes a jacking member 13, and the jacking member 13 movably penetrates through the through hole 113 and is in sliding abutment with the hole wall of the inclined hole 122; the lifting member 13 moves along the through hole 113 and slides relative to the wall of the inclined hole 122, so that the cavity 12 slides along the wall of the receiving groove 112 and moves closer to or away from the core 22.

It will be appreciated that one end of the jack 13 passes through the via 113 and is movable back and forth relative to the via 113. Meanwhile, the cavity 12 is provided with an inclined hole 122 corresponding to the via hole 113, and the shape of the inclined hole 122 is matched with one end of the jacking piece 13 far away from the via hole 113. Specifically, the inclined hole 122 is disposed in an upward inclined manner in a direction gradually away from the via hole 113, and one end of the jacking piece 13 penetrating through the inclined hole 122 is also disposed in an upward inclined manner, and it can be understood that the upper surface and the lower surface of one end of the jacking piece 13 penetrating through the inclined hole 122 are both disposed as inclined surfaces, wherein the upper surface is slidably abutted against the top wall of the inclined hole 122, and the lower surface is slidably abutted against the bottom wall of the inclined hole 122. Specifically, the jacking piece 13 is further provided with a stop surface, the stop surface and the upper surface of the jacking piece 13 are arranged at an included angle, namely, a step surface is formed on the upper surface of the jacking piece 13, and the stop surface is used for being in limit abutting contact with the cavity insert 12 so as to stop the cavity insert 12.

For example, when the jacking piece 13 moves towards the direction away from the cavity 12, the jacking piece 13 slides and abuts against the hole wall of the inclined hole 122, and meanwhile, because the inclined hole 122 is arranged obliquely, the jacking piece 13 jacks up the cavity 12 gradually, so that the cavity 12 moves upwards in the accommodating groove 112; on the contrary, when the knock-up member 13 moves toward the cavity insert 12, one end of the knock-up member 13 gradually passes through the inclined hole 122, and the cavity insert 12 moves downward by the guide of the inclined hole 122. It will be appreciated that the end of the jacking members 13 remote from the inclined apertures 122 may be arranged to be connected to a drive arrangement, such that the drive arrangement drives the jacking members 13 to move back and forth.

Referring to fig. 3 and fig. 5, in an embodiment, positioning blocks 14 are convexly disposed on two opposite side walls of the accommodating groove 112, positioning grooves 123 are disposed on two opposite side walls of the cavity 12 corresponding to the positioning blocks 14, and the positioning blocks 14 are accommodated in the positioning grooves 123 and slidably abut against the cavity 12.
