T-shaped first piston is connected to, T-shaped second piston is plugged with the horizontal part of hydraulic channel, clamps and is bolted with seat and second
The opposite fishbolt of piston, forms counterbore on the bottom face of fishbolt, second piston is fixed with block through external thread sleeve
And be plugged in the counterbore of fishbolt, external thread sleeve is screwed onto in the counterbore of fishbolt；One end of pressing plate forms boss, convex
Fulcrum is plugged with platform, the downside of boss is equipped with briquetting, and the both sides of briquetting form journal stirrup, and journal stirrup is hinged on fulcrum.
Preferably, it is described to clamp the oiling passage for forming on seat and being connected with hydraulic channel, the outlet of oiling passage
End is fixed with plug.
Preferably, the articulated shaft upper sleeve has a torsional spring, one end of torsional spring be fixed on clamp on seat, the other end is fixed on
On pressing plate.
Preferably, the first piston upper sleeve has stop collar, and stop collar, which is fixed on, to be clamped on seat.
Preferably, the bar footpath of the second piston is less than the diameter of external thread sleeve inner ring.
Preferably, the length of the first piston is more than articulated shaft to the distance for clamping a upper surface.
The beneficial effects of the utility model are：It contacts the rectification of the pressure holding contact surface of mould for face, while by second
Connection rectification between piston and fishbolt is radial type, and the fit precision between fishbolt and second piston is low, saves
Cost of manufacture.
