The connecting block 4 is formed with a fourth clamping portion 41 along the vertical direction, and the second clamping portion 23 is clamped with the fourth clamping portion 41 in a matched manner and can slide relatively along the vertical direction. In this embodiment, the second engaging portion 23 is a fastening block disposed along the vertical direction, and the fourth engaging portion 41 is a fastening groove disposed along the vertical direction. The clamping block is matched with the clamping groove in a sliding clamping mode, so that the clamping block can only slide along the vertical direction.
In other embodiments, the clamping groove and the clamping block can be interchanged, that is, the second clamping portion 23 is the clamping groove formed along the vertical direction, the fourth clamping portion 41 is the clamping block formed along the vertical direction, and the clamping block and the clamping groove are matched and slidably clamped together.
One end of the second joint module 3 is fixedly connected with the connecting block 4, and the other end of the second joint module is matched with the second groove structure 12.
Further, in this embodiment, in order to connect the second clamping portion 23 and the fourth clamping portion 41 more stably, a first connecting hole is formed in the connecting block 4, and the transmission block 5 passes through the first connecting hole and is connected to the first mold assembly 2. And the fourth catching portions 41 are provided on the inner walls of the first connecting hole, preferably two fourth catching portions 41 are provided on the opposite inner walls, respectively. Meanwhile, two second clamping parts 23 are correspondingly arranged on two opposite side surfaces of the first mold clamping module 2. Therefore, the two sides of the first mold closing module 2 are stressed uniformly, and the movement is more stable during demolding.

Because first joint portion 22 and third joint portion 52 cooperation joint, the relative motion direction between transmission block 5 and the first matched mould 2 can only be followed first domatic 21, simultaneously because second joint portion 23 and fourth joint portion 41 cooperation joint, the relative motion direction between connecting block 4 and the first matched mould 2 can only be followed vertical direction. The two are superposed, and when the transmission block 5 moves horizontally towards the direction departing from the workpiece 1, the first die assembly 2 moves upwards along with the transmission block, and is separated from the first groove structure 11. The driving block 5 is then in contact with the stop 61 and slides the sliding seat 6 along the base 7 via the stop 61. Base 6 and connecting block 4 fixed connection, connecting block 4 and second compound die block 3 fixed connection drive second compound die block 3 along the horizontal direction upward movement, with the separation of second groove structure 12, connecting block 4 drives first compound die block 2 in the horizontal direction through second joint portion 23 and the cooperation joint of fourth joint portion 41 and moves together simultaneously.
