The I-shaped base 21 structure can provide better support and stability, making the entire mold body 11 system more firm and stable during the operation process, reducing vibration and shaking. Moreover, since the middle part of the I-shaped base 21 is wider, the pressure applied during demoulding can be dispersed to a larger area, reducing the concentrated pressure on the bottom of the mold body 11, thereby reducing the risk of deformation and wear. Finally, by using the fixing member 22, the mold body 11 can be fixed to ensure that the mold body 11 maintains a stable position during the production process.

[0031] Working principle:

[0032] As Figure 1 - Figure 4 shown, when the present utility model is in use, according to the needs of the user, by rotating the lead screw 18, it will move at its original position as it rotates.
