When the mold is opened, the core-pulling slide block 22 moves reversely to the X axis relative to the movable mold plate 5, when the mold is closed, the core-pulling slide block 22 moves forward to the X axis relative to the movable mold plate 5, and the movement of the core-pulling slide block 22 to the X axis is buffered through the arrangement of the elastic piece 27, so that the core-pulling slide block 22 is prevented from being collided with other structures by mistake. Here, the elastic member 27 is a spring, and the spring is in a compressed state, and when the mold is opened, the spring provides power for the core pulling slide 22 to move in the reverse direction of the X axis.
As shown in fig. 2 and 6, a receiving groove 28 is disposed on the core back slider 22 and/or the movable mold plate 5, and the receiving groove 28 is used for receiving the elastic member 27. That is, the spring is at least partially received in the receiving groove 28, and the receiving groove 28 is used for limiting the displacement of the spring along the radial direction of the spring.
