Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in Figure 3, Figure 4, two-plate injection machine, comprises fixed form 3, moving die plate 1, upper lower link 8, and between fixed form 3, moving die plate, 1 is connected by upper lower link 8, and moving die plate 1 is supported by two boards shoe slipper 2.
Above-mentioned moving die plate 1 arranges cohesion nut 6, and in obvolvent, lower link 8, is shown in Fig. 5.
As shown in Figure 5, moving die plate 1 also arranges rapid mould-moving oil cylinder 7, by the quick mobile moving die plate 1 of rapid mould-moving oil cylinder 7 during die sinking.
As shown in Figure 9, above-mentioned pull bar 8 tail end arranges Mode-locking oil cylinder 12, and the cylinder tube of Mode-locking oil cylinder fixedly leads gripper shoe 24 by screw, and slide block 23 is fixed in gripper shoe 24 by screw.
The cylinder body of above-mentioned pumping rod oil cylinder is fixed in gripper shoe 24, and the piston rod external part 30 of pumping rod oil cylinder is fixed on cap ned 21 by piston rod attachment 29, sees Figure 10.
Also clamping device is provided with between above-mentioned Mode-locking oil cylinder and fixed form, the clamping device of the present embodiment comprises the groove 19 be arranged on Mode-locking oil cylinder and the hydraulically operated fixture 18 be fixed on fixed form, when Mode-locking oil cylinder with can extract out pull bar move into place time, hydraulically operated fixture 18 action, its plug is inserted in groove 19, thus Mode-locking oil cylinder is located, see Fig. 6, Fig. 8.
Certain clamping device also can be other similar means.
As shown in Figure 7, also guiding mechanism is provided with between above-mentioned Mode-locking oil cylinder and fixed form, the guiding mechanism of the present embodiment comprises the reset positioning pin 14 be fixed on fixed form 3 and the gathering sill 13 be arranged on Mode-locking oil cylinder, Mode-locking oil cylinder can be made like this to move original position with pull bar 8 can be extracted out, ensure that clamp system accurately clamps Mode-locking oil cylinder.
Certain guiding mechanism also can be other guiding mechanisms.
Above-mentioned cap ned 21 one end is also provided with limited block 5, spacing when encountering limited block when Mode-locking oil cylinder moves with extraction pull bar, prevents the excessive pull-out of pull bar 8, sees Fig. 4.
The whole process of installation or more mold exchange is as follows:
1, for convenience of installation mold, the pull bar of two-plate injection machine one side first can extracted out by pull bar is extracted out, and detailed process is as follows:
After cohesion nut 6 is opened under the effect of band-type brake oil cylinder (not shown in FIG.), under rapid mould-moving oil cylinder 7 acts on, moving die plate 1 shrinks back, and completes die sinking action; Hydraulically operated fixture 18 is retracted from the groove 19 of Mode-locking oil cylinder cylinder 12 subsequently, and Mode-locking oil cylinder cylinder 12 locking state is removed; Then pumping rod oil cylinder 4 works, drive gripper shoe 24, Mode-locking oil cylinder bonnet 20, Mode-locking oil cylinder cylinder 12, pull bar 8 can be extracted out retreat simultaneously, pull bar 8 is extracted out from moving die plate 1, moving to pull bar 8 not to block between fixed form and moving die plate till lateral space, now, injection machine main body side only has the pull bar 8 of bottom to stop, can carry out installation or the replacing of mould thus from the side, can easily mould laterally be hung at lower height or move between solid plate and moving platen, see Fig. 2.
2, after installing mould, then pull bar is inserted original position, specific as follows:
Pumping rod oil cylinder 4 works, and drives gripper shoe 24, Mode-locking oil cylinder bonnet 20, Mode-locking oil cylinder cylinder 12 simultaneously, can extract pull bar 8 out and move toward fixed form 3 direction; Lead through reset positioning pin 14, Mode-locking oil cylinder cylinder 12 and fixed form 3 are fitted; After laminating, hydraulically operated fixture 18 works, and is pinned by Mode-locking oil cylinder cylinder 12; Rapid mould-moving oil cylinder 7 drives moving platen 1 to complete matched moulds subsequently; Last fixed mould, equally with common injection machine carries out normal operating.
Above-mentioned installation process is simply illustrated to see Fig. 2.
Pull bar is extracted out for fore side by the present embodiment, and the pull bar of not operation side can also be extracted out by same method.
