The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention.
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.
On above-mentioned moving die plate 1, cohesion nut 6 is set, for lower link in obvolvent 8, sees Fig. 5.
As shown in Figure 5, rapid mould-moving oil cylinder 7 is also set on moving die plate 1, during die sinking, can carrys out fast moving moving die plate 1 by rapid mould-moving oil cylinder 7.
As shown in Figure 9, above-mentioned pull bar 8 tail ends arrange Mode-locking oil cylinder 12, on the cylinder tube of Mode-locking oil cylinder, by screw, fixedly lead gripper shoe 24, 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.
Between above-mentioned Mode-locking oil cylinder and fixed form, be also provided with clamping device, the clamping device of the present embodiment comprises the groove 19 being arranged on Mode-locking oil cylinder and is fixed on the hydraulically operated fixture 18 on fixed form, when Mode-locking oil cylinder is with can extract pull bar out and move into place time, hydraulically operated fixture 18 actions, its plug is inserted in groove 19, thereby make Mode-locking oil cylinder location, see Fig. 6, Fig. 8.
Certainly clamping device also can be other similar means.
As shown in Figure 7, between above-mentioned Mode-locking oil cylinder and fixed form, be also provided with guiding mechanism, the guiding mechanism of the present embodiment comprises the reset positioning pin 14 being fixed on fixed form 3 and is arranged on the gathering sill 13 on Mode-locking oil cylinder, can make like this Mode-locking oil cylinder move original position with extracting pull bar 8 out, guarantee that clamp mechanism accurately clamps Mode-locking oil cylinder.
Certainly guiding mechanism also can be other guiding mechanisms.
Above-mentioned cap ned 21 one end are also provided with limited block 5, and Mode-locking oil cylinder with extracting out while encountering limited block when pull bar moves and spacing, prevents excessively pulling 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 that first pull bar can be extracted out 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 7 effects of rapid mould-moving oil cylinder, 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 states are removed; Then pumping rod oil cylinder 4 work, drive gripper shoe 24, Mode-locking oil cylinder bonnet 20, Mode-locking oil cylinder cylinder 12, can extract pull bar 8 out and retreat simultaneously, pull bar 8 is extracted out from moving die plate 1, moving to pull bar 8 does not block between fixed form and moving die plate till lateral space, now, injection machine main body one side only has the pull bar 8 of bottom to stop, can carry out from the side installation or the replacing of mould thus, can easily mould laterally be hung in or be moved between solid plate and moving platen at lower height, see Fig. 2.
2, install after mould, then pull bar is inserted to original position, specific as follows:
Pumping rod oil cylinder 4 work, 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 directions; Through reset positioning pin 14 guiding, Mode-locking oil cylinder cylinder 12 and fixed form 3 laminatings; After laminating, hydraulically operated fixture 18 work, pin 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.
Fig. 2 is shown in the simple signal of above-mentioned installation process.
The present embodiment be take fore side and pull bar is extracted out as example, and the pull bar of not operation side can also be extracted out by same method.
