The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
As Fig. 1, Fig. 2, shown in Figure 3, distinguish the disk shaft composite device of double coloured plastic injection machine, the fixing servomotor 40 of a side on its moving platen 1 connects gear 25 with transition gear 27,28 on the servomotor 40, servomotor torsion is passed to toothed disc 26; Rotating shaft cover 15 in toothed disc 26 is fixed to by flat key 30, interior rotating shaft cover 15 is positioned on the outer shaft cover 9 by bearing 16,18 and clamp nut 10, and outer shaft overlaps 9 and is fixed on the moving platen 1 by bearing 17,19 and clamp nut 22; Rotating disk 2 is fixed on the outer shaft 9 by screw and alignment pin, and rotating disk 2 is connected by adpting flange 11 with interior rotating shaft 15; Rotating shaft oil cylinder 37 is fixed on the moving platen 1 by flange 36, and the rotating shaft piston rod is connected with rotating shaft 12 by 35,34,33,32 bindiny mechanisms that form, and rotating shaft 12 is connected with interior rotating shaft cover 15 by dive key.
When said structure was used as rotating disc type, matched moulds structure matched moulds compressed the mould that is contained on the rotating disk, and interior big plane of rotating disk this moment and moving platen 1 big plane fit tightly, and two penetrate platform to mould type intracavitary administration molten plastic.Work as pressurize; the clamping die sinking of cooling back; this moment, rotating disk 2 broke away from the big plane of moving platen under the effect of rotating disk ejecting mechanism 7; die sinking on earth the time one side ejecting mechanism eject goods; servomotor 40 drives down then; by connecting gear 25; transition gear 27; toothed disc 26 is given in 28 transmissions; rotating shaft cover 15 in toothed disc 26 drives; by adpting flange 11; drive rotating disk 2 and outer shaft 9, clockwise or be rotated counterclockwise 180 degree, put in place and confirm that back positional cylinder 39 drives alignment pins and accurately locatees disk position; for preventing rotating disk 2 overshoots; ad hoc meter overshoot alignment pin 3 plays the overshoot protection effect, and rotating disk 2 is in rotation process simultaneously; can in computer, set the rotating disk decelerate position; signal is given servomotor 40 when putting in place, so that rotating disk 2 underspeeds the positioning accuracy of raising rotating disk 2 when slowing down the position.After rotating disk is accurately located, begin matched moulds and advance, the next working cycles of row.Mold cools down can be carried out mold cools down through matched moulds fixed head center by cooling water by system in said process, twines to prevent cooling water pipe.
When above-mentioned matched moulds structure is used as rotary shaft, take adpting flange 11 earlier apart, rotating shaft cover 15 and outer shaft cover 9 separates with rotating disk 2 in making, the alignment pin of positional cylinder 39 is in running order, fix rotating disk 2, simultaneously one signal output is arranged all the time on the positional cylinder 39, fix to guarantee rotating disk 2 pin that is positioned near switch.The course of work is: matched moulds structure matched moulds, compress the mould that is contained on the rotating disk, and interior big plane of rotating disk this moment and moving platen 1 big plane fit tightly, and two penetrate platform to mould type intracavitary administration molten plastic.Work as pressurize; the clamping die sinking of cooling back; this moment, rotating disk 2 broke away from the big plane of moving platen under the effect of rotating disk ejecting mechanism 7; die sinking on earth the time one side ejecting mechanism eject goods; straight line at rotating shaft oil cylinder 37 ejects under the effect; rotating shaft 12 is held out the mould die joint with the mould inner mould core; after obtaining the affirmation of rotating shaft oil cylinder 37 position signallings; under servomotor 40 drives; by connecting gear 25; transition gear 27; toothed disc 26 is given in 28 transmissions; rotating shaft cover 15 in toothed disc 26 drives by connecting dive key, makes rotating shaft do clockwise or be rotated counterclockwise 180 degree; be contained on the toothed disc 26 near switch output signal; after confirming that the position puts in place, rotating shaft oil cylinder 37 is done straight line and is retreated under the effect of hydraulic oil; core rod in the mould is returned in the mold cavity, be ready to the beginning of next circulation.Mold cools down can directly insert mould goods in the mould are cooled off in the said process.
No matter the disk shaft composite device is as rotating disc type or rotary shaft, its positive and negative 180 degree rotation location all be by be arranged on rotating disk or the toothed disc near the switch electric eye, rotating disk or rotating shaft rotation time-division supplementary biography pass rotating disk or rotating shaft clockwise with the position signalling that rotates counterclockwise.These parts all belong to existing structure, do not describe in detail.
