Further, the vibrator comprises a supporting angle iron and a buzzer arranged in the supporting angle iron, and the adhesion between the blank and the die is broken through vibration of the buzzer, so that the demolding effect is improved.
Further, a cooling pipe is arranged in the fixed die, and two ends of the cooling pipe are connected with connecting ports. Is used for rapidly cooling the embryo body.
Furthermore, the cooling pipe is a coil pipe, so that the heat conduction efficiency is further improved.
Further, the bolt is stainless steel, and the magnet block is arranged in the movable mould and corresponds to the bolt insertion position, and is attracted by the magnet after the bolt is inserted, so that the bolt is not easy to loosen.
The beneficial effects of the utility model are as follows: the vibrator is utilized to drive the blank and the mould to vibrate, so that the adhesion relationship between the sticky lipid on the surface of the blank and the mould is destroyed, and the demoulding effect is improved.
