Aluminum-alloy wheel air injection machine safety insurance mechanism, be made up of safety insurance mechanism (7), board stationary platen (8), board moving bedplate (9), bed die (10) and mold (11), it is characterized in that: described pull bar (4) is fixed on board moving bedplate, the piston of hydraulic jack (1) stretches out or resets, promote latch (2) to shift out or insert in the skewed slot of pull bar (4), realize safety insurance mechanism (7) to the unblock of board moving bedplate (9) or locking.The present invention, moving bedplate can drive pull bar freely up and down movable, and namely safety insurance mechanism is in open state; When air injection machine is out-of-work time, hydraulic cylinder piston bounces back, and latch inserts the skewed slot of pull bar under the force of a spring, and the moving bedplate of steady brace cannot be fallen, and has ensured the personal safety of operator by it.

Description

Aluminum-alloy wheel air injection machine safety insurance mechanism
Technical field
The invention belongs to metal casting machine technical field, refer more particularly to the safety insurance mechanism of aluminum alloy low-pressure casting machine.
Background technology
The manufacture of present automobile industry aluminum-alloy wheel generally adopts air injection machine to cast out aluminum-alloy wheel blank, and its equipment is made up of frame, hydraulic system, electric-control system, mould etc.Its production process operates electric-control system by operator makes the mould be fixed in frame automatically close, then aluminium liquid automatically enters mould and realizes blank and fill type, finally operates electric-control system by operator and completes mold open, frame lifting, automatically gets the process of workpiece.This kind of method operator must enter board cleaning mould, maintenance etc. in casting process, and it certainly exists frame and declines suddenly due to hydraulic pressure or mechanical breakdown and the injury that causes personnel.
Summary of the invention
For above problem, the object of the present invention is to provide a kind of aluminum-alloy wheel air injection machine safety insurance mechanism, is by installing a set of safety insurance mechanism on board, when board is normally worked, its insurance institution is in open state, does not affect the normal operation of board; When board is out of service, its insurance institution is in the close position, realizes mechanical forced locking, thus ensures the personal safety of operator to greatest extent.
The technical solution used in the present invention is: aluminum-alloy wheel air injection machine safety insurance mechanism, be made up of safety insurance mechanism, board stationary platen, board moving bedplate, bed die and mold, safety insurance mechanism is fixed on board moving bedplate, can move up and down along with board moving bedplate, the below of board moving bedplate is provided with mold, electric-control system makes the upper/lower die be fixed in frame automatically close or open, and it is characterized in that: described safety insurance mechanism is made up of hydraulic jack, movable latch, back-moving spring, pull bar and latch pressing plate; It is characterized in that: described pull bar is fixed on board moving bedplate, the piston of hydraulic jack stretches out or resets, and promotes latch and shifts out or insert in the skewed slot of pull bar, realizes safety insurance mechanism and unlocks or locking board moving bedplate.
Described pull bar radially side is provided with jagged skewed slot, latch and back-moving spring are located in latch pressing plate, latch pressing plate and hydraulic jack are fixed on board stationary platen, one end of pull bar and board moving bedplate are fixed, mold can be driven freely up and down movable.
The piston of described hydraulic jack stretches out, and promotion latch moves to left, and pull bar rotates, and latch shifts out in the skewed slot of pull bar, promotes back-moving spring and moves to left, unlock, and board moving bedplate drives upper and lower mould automatically close or open.
The piston reset of described hydraulic jack, promote latch and moved to right by the elastic force of back-moving spring, pull bar rotates, and latch enters in the skewed slot of pull bar, and pull bar locks, and board moving bedplate closes locking.
The present invention, moving bedplate can drive pull bar freely up and down movable, and namely safety insurance mechanism is in open state; When air injection machine is out-of-work time, hydraulic cylinder piston bounces back, and latch inserts the skewed slot of pull bar under the force of a spring, and the moving bedplate of steady brace cannot be fallen, and has ensured the personal safety of operator by it.

Fig. 2 is that safety insurance mechanism unlocks schematic diagram.
Fig. 3 is the top view of Fig. 2.
Fig. 4 is that safety insurance mechanism closes locking schematic diagram.
Fig. 5 is the top view of Fig. 4.
In figure: 1 hydraulic jack, 2 movable latch, 3 back-moving springs, 4 pull bars, 5 latch pressing plates, 6 pull bar skewed slots, 7 safety insurance mechanisms, 8 stationary platens, 9 moving bedplates, 10 bed dies, 11 molds.
Detailed description of the invention
Known by Fig. 1, aluminum-alloy wheel air injection machine safety insurance mechanism, be made up of safety insurance mechanism 7, board stationary platen 8, board moving bedplate 9, bed die 10 and mold 11, safety insurance mechanism 7 is fixed on board moving bedplate 9, can move up and down along with board moving bedplate 9, the below of board moving bedplate 9 is provided with mold 11, electric-control system makes the upper/lower die be fixed in frame automatically close or open, and it is characterized in that: described safety insurance mechanism 7 is made up of hydraulic jack 1, movable latch 2, back-moving spring 3, pull bar 4 and latch pressing plate 5; Described pull bar 4 is fixed on board moving bedplate, and the piston of hydraulic jack 1 stretches out or resets, and promotes latch 2 and shifts out or insert in the skewed slot of pull bar 4, realizes safety insurance mechanism 7 pairs of board moving bedplates 9 and decontrols unblock or closed locking.
Being known by Fig. 2, Fig. 3, is that safety insurance mechanism unlocks schematic diagram.Pull bar 4 radially side is provided with jagged skewed slot 6, latch 2 and back-moving spring 3 are located in latch pressing plate 5, latch pressing plate 5 and hydraulic jack 1 are fixed on board stationary platen 8, one end of pull bar 4 and board moving bedplate 9 are fixed, mold 11 can be driven freely up and down movable.The piston of hydraulic jack 1 stretches out, and promote latch 2 and move to left, pull bar 4 rotates, and latch 2 shifts out in the skewed slot 6 of pull bar 4, promotes back-moving spring 3 and moves to left, unlock, and board moving bedplate 9 drives upper and lower mould automatically close or open.
Being known by Fig. 4, Fig. 5, is that safety insurance mechanism closes locking schematic diagram.The piston reset of described hydraulic jack 1, promote the elastic force of latch 2 by back-moving spring 3, move to right, pull bar 4 rotates, and latch 2 enters in the skewed slot 6 of pull bar 4, and pull bar 4 locks, and board moving bedplate 9 closes locking.
