Preferably, the prepressing piece is cylindrical and is arranged on the support frame at equal intervals, a prepressing spring is sleeved outside the prepressing piece, and one end of the prepressing spring is fixed on the support frame.

Preferably, the pressure plate is concave and is provided with a concave cavity matched with the workpiece.

Preferably, the pre-pressing cylinder and the clamping cylinder are respectively fixed on supporting plates on two sides, and a connecting rod is fixed between the supporting plates.

Preferably, the two sides of the base are symmetrically provided with fixing plates, and the fixing plates are uniformly provided with a plurality of fixing holes.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses a clamping piece mechanism carries out the pre-compaction through pre-compaction cylinder drive casting die to the work piece earlier, ensures the extraction of manipulator, has avoided easily leading to the problem of waiting to process work piece dislocation, aversion because of static, remanence, extraction force control are not good etc. and the centre gripping is stable, reliable.

2. Move by pre-compaction cylinder earlier and promote pre-compaction spare pre-compaction work, drive the clamp plate by the centre gripping cylinder and carry out further centre gripping to the work piece after that, the structural design of this practical clamping piece mechanism pre-compaction spare and clamp plate all set up on the support frame, and simple structure, reasonable in design and centre gripping effect are good.
