The specific embodiment
As depicted in figs. 1 and 2, this vertical die-casting machine mold closing mechanism comprises die cylinder 1, top board 7, moving platen 9, quiet template 11, guide pillar 4, column 2, pedestal 12 and linkage 5. columns 2 have two, be positioned at both sides, the lower end of column and pedestal 12 fix. and quiet template 11 is fixed on the bottom of column, with pedestal near. top board 7 is fixed on the top of column. guide pillar 4 has four, divide four jiaos that are listed in top board 7 and quiet template 11, the lower end of guide pillar and quiet template fix, four jiaos of top board are linked on the guide pillar. and die cylinder 1 is fixed on the center of top board 7 upper surfaces. as shown in Figure 3, the piston rod 13 of die cylinder stretches out downwards. and four jiaos of moving platen 9 are linked on the guide pillar 4, be slidingly matched with guide pillar, the top of moving platen is connected with the piston rod 13 of die cylinder by linkage 5. and screw thread is arranged at the top of guide pillar, be with pinion 3 on the screw thread on the top of guide pillar, pinion is close to mutually with the upper surface of top board, have on the inner peripheral surface of pinion with guide pillar on the screw thread of threads engaged. the outside of pinion is with a pinion cover 19, the pinion cover fixes with the upper surface of top board. and there is a gear wheel 6 at the middle part of the upper surface of top board, this gear wheel is meshed with pinion on four guide pillars. and the top board edge also has a manual pinion 20, and this manual pinion is meshed with gear wheel.
With rocking handle rotation manual pinion 20, manually pinion drives gear wheel 6 rotations, gear wheel drives four pinions 3 and rotates, because the pinion cover limits pinion, make top board 7, die cylinder 1, linkage 5 and moving platen 9 with respect to guide pillar 4 and quiet template 11 upper and lower moving, thereby regulate the distance between moving platen and the quiet template, to adapt to the needs of different-thickness mould, regulate meticulousr, also be convenient to the operation.After adjusting is finished, pinion is held out against, and lock screw is locked with nut with lock screw.
As Fig. 2, Fig. 4 and shown in Figure 5, in this vertical die-casting machine mold closing mechanism, described linkage 5 is a hyperbolic elbow linkage, comprises piston rod contiguous block 14, fixed block 17, first connecting rod 15, second connecting rod 16 and third connecting rod 18.Piston rod contiguous block 14 is fixed on the lower end of piston rod, described fixed block, first connecting rod, second connecting rod and third connecting rod have two groups, divide the both sides that are listed in piston rod, every group fixed block 17 be fixed on top board 7 the edge below, one end and the piston rod contiguous block 14 of first connecting rod 15 are hinged, the upper end of the other end of first connecting rod and third connecting rod 18 is hinged, the limit portion of the lower end of third connecting rod and moving platen 9 is hinged, one end of second connecting rod 16 and the upper end of third connecting rod are hinged, and the bottom of the other end of second connecting rod and fixed block 17 is hinged.
This hyperbolic elbow linkage has amplification to the thrust of piston rod, moves down when finishing mould assembling action at piston rod, and the thrust of moving platen is the several times of piston rod thrust, and this moment moving platen translational speed the slowest.When moving on the piston rod, the translational speed of moving platen is come more soon.This manner of execution just in time meets the requirement of matched moulds process, and just can obtain enough clamp forces with the die cylinder of smaller power.
Linkage among Fig. 2 is in piston rod and moves down near finishing the mould assembling action state, and the linkage among Fig. 5 is on the piston rod state that moves, moves on the moving platen.
As depicted in figs. 1 and 2, can also there be a mold mounting plate 10 quiet template 11 tops in this vertical die-casting machine mold closing mechanism, and four jiaos of mold mounting plate are enclosed within on four guide pillars 4, accompany spring between mold mounting plate and the quiet template.This structure, counterdie is fixed on the mold mounting plate.During matched moulds, under the effect of mold clamping force, mold mounting plate 10 moves down with quiet template 11 and fits, and mould contacts with the nozzle of injection mechanism.During die sinking, under the effect of spring force, move in the mold mounting plate short distance, counterdie and nozzle are separated, the automatic breaking cast gate separates thermal source, makes to be easy to the demoulding, can also avoid mould overheated, avoids nozzle temperature to descend and the generation clogging.
As depicted in figs. 1 and 2, also have two drawing cylinders 24 on the pedestal 12 of this vertical die-casting machine mold closing mechanism, drawing cylinder be positioned at pedestal panel 22 below, relative two jiaos of the piston rod of drawing cylinder and quiet template 11 fix.Drawing cylinder makes quiet template 11 and guide pillar 4, moving platen 9 and top board 7 move up and down with respect to column 2 with adopting, thereby adjusts its height, so that quiet template and top mould thereof are in the suitable position of the nozzle top of injection mechanism.
23 is guide post among Fig. 3, is used for the moving direction of stable plunger bar contiguous block 14, and 8 is the guide post fixed head, and with adopting stable guide post, 21 is the workpiece knock-pin, is used for after the die sinking workpiece being ejected from patrix.
