Here, the elastic member 27 is a spring, which is in a compressed state, and which provides power for the core-pulling slider 22 to move in the X-axis reverse direction when the mold is opened.
As shown in fig. 2 and 6, the core-pulling slide 22 and/or the movable mold plate 5 are provided with a receiving groove 28, and the receiving groove 28 is used for receiving the elastic member 27. That is, the spring is at least partially accommodated in the accommodating groove 28, and the accommodating groove 28 is used for limiting displacement of the spring in the radial direction of the spring.

Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention, and the scope of the invention should be assessed accordingly to that of the appended claims.
