Description
Technical field
The utility model relates to be pressed and molded field, more particularly to a kind of hydraulic crank arm compression molding device.
Background technique
The folding and locking of the moving die plate of traditional semi-automatic or full-automatic compression molding device need hydraulic cylinder
It completes, hydraulic cylinder is under the hydraulic oil effect that hydraulic system provides, and from the oil inlet of piston-rodless end, piston rod stretches out oil cylinder,
Under the promotion of piston rod, moving die plate is run under the guiding of load-bearing guide rod to the direction of fixed form, completes moving die plate
Mould assembling action.After moving die plate molding is to fixed form, piston rod cannot continue to stretch out, at this point, hydraulic system can provide height
Pressure oil completes the locking of moving die plate to hydraulic cylinder, locks pressure generally in 11-20Mpa.When die sinking, hydraulic cylinder is in liquid
Under the hydraulic oil effect that pressure system provides, from there is tailpiece of the piston rod oil inlet, piston rod retracts oil cylinder, under the pulling of piston rod, moves

It is hinged on the right side of crank arm b tail end and the rack, hydraulic cylinder, hydraulic cylinder (4) are hingedly installed on the right side of the rack (1)
Piston rod and the b that cranks arm it is hinged.Using the structure, the locking of moving die plate directly locks change by the hydraulic cylinder of conventional molding machines
At mechanical interlocking, clamp force can be reduced, so the piston area of hydraulic cylinder also can reduce, movement speed is faster；Together
When reduce energy consumption and equipment cost；But the device is horizontally formed mechanical dead point by a and b that cranks arm that cranks arm, and leads to
Crossing hydraulic cylinder drives the movement for a that cranks arm to drive the b that cranks arm, so that forming the hinge joint of the crank arm a and the b that cranks arm of mechanical dead point
Stability is poor.
