[0032] like Figure 1 、 Figure 2 As shown, the main body 1 is slidably connected to the sliding part 2, so that the main body 1 and the sliding part 2 can slide relative to each other along the length direction of the mold core.

[0033] In this embodiment, a sliding groove 23 is formed on the side wall of the installation groove 22 along the length direction of the mold core, and a slider 11 is provided on the side wall of the main body 1 , and the slider 11 is slidably connected to the sliding groove 23 .

[0034] Preferably, the cross-sectional shape of the slide groove 23 is a dovetail shape, and the slide groove 23 passes through the end of the sliding part 2 away from the finger body 21. The cross-sectional shape of the slider 11 matches the cross-sectional shape of the slide groove 23, so that the slider 11 will not loosen along the lateral direction of the mold core and can only slide along the length direction of the mold core, thereby improving the stability of the sliding part 2 and the main body 1 when sliding relative to each other.

[0035] As another solution, the positions of the slide groove 23 and the slider 11 may be interchanged, or the shape of the slide groove 23 may be designed to be a "T" shape.

[0036] Of course, the sliding portion 2 may also be directly slidably engaged with the mounting groove 22 without the need to provide an additional sliding groove 23 .

[0037] like Figure 1 、 Figure 3 、 Figure 4 As shown, a connection mechanism 3 is provided between the main body 1 and the sliding part 2 to connect or separate the two.

[0041] The working principle of this embodiment is as follows:

[0042] When the mold core is in the working state, the side of the mounting groove 22 close to the finger body 21 is in contact with the side of the main body 1 close to the sliding part 2, and one side of the limiting portion 342 is in contact with the side of the connecting groove 31 close to the finger body 21. There is a gap between the other side of the limiting portion 342 and the limiting block 32. The mounting seat 343 is located in the channel 33 and is in contact with the end of the limiting portion 342.

[0043] When demoulding is required, the main body 1 moves a certain distance relative to the sliding part 2, so that there is a certain space between the main body 1 and the sliding part 2. The sliding part 2 rotates with the product, so that the limiting part 342 of the main body 1 moves to the position aligned with the channel 33. The sliding part 2 and the main body 1 can be separated by sliding, so that the main body 1 can slide out relative to the product and be demoulded smoothly.
