Description
Technical field
The utility model relates to a kind of annex of injection machine, specifically is a kind of mould whirligig of clear double coloured plastic injection machine.
Background technology
Along with the continuous development of injection machine technology, the technology of double-shot moulding in the application in injection machine field more and more widely.Existing double coloured plastic injection machine is divided into mixed doubles look injection machine, clear double coloured plastic injection machine, wherein the injection moulding of mixed doubles look is prior plastics fusion plastification in two barrels with two kinds of required different colours, be expelled in the mould by same nozzle, therefore the product colour that comes out is a colour mixture, and its color is unordered change at random.And to produce two kinds of double-colored goods that color limit is clearly demarcated, and then must use double coloured plastic injection machine clearly, promptly must adopt two barrels, so the device of its control mould rotation just seems particularly important.The version of at present clear double coloured plastic injection machine control mould rotation is varied, wherein the rotary turnplate structure arranged than widespread usage, it is all to be installed in two secondary moulds on the rotary turnplate, the rotary turnplate cylindrical is processed into gear wheel, its rotation is to drive the gear wheel rotary turnplate by the driver pinion that is fixed on the fluid motor-driven motor drive shaft on the moving platen, the gear wheel rotary turnplate is rotated back and forth between two secondary moulds, and the repeatable accuracy that the gear wheel rotary turnplate is rotated is to locate by the alignment pin that is fixed on the moving platen.But there is following shortcoming in this mould whirligig: a side that 1. all is installed in the big plane of moving platen owing to gear wheel rotary turnplate, driving wheel pinion, take very big space, thereby greatly wasted the spacing in the injection machine pull bar and the installing space of mould.2. therefore gear wheel rotary turnplate processed complex causes the manufacturing cost height.
The utility model content
Technical problem to be solved in the utility model is that a kind of mould whirligig that can reduce the clear double coloured plastic injection machine of the shared space of mould whirligig, low cost of manufacture is provided.
For solving the problems of the technologies described above, the mould whirligig of a kind of clear double coloured plastic injection machine that the utility model provides, comprise rotating shaft, rotary turnplate, alignment pin, described rotary turnplate is rotatably connected on the moving platen by rotating shaft, described alignment pin and moving platen tight fit, one end of described rotating shaft and rotary turnplate tight fit, the other end is provided with rack and pinion drive mechanism, described gear is a tight fit in the rotating shaft, described tooth bar is connected on the moving platen, and described alignment pin and rotary turnplate are slidingly matched.
After having adopted such scheme, the utility model compared with prior art has the following advantages: owing to be provided with rack and pinion drive mechanism at the other end of rotating shaft, make the transmission mechanism of mould whirligig simpler, volume is littler, therefore can reduce the shared space of mould whirligig, also reduce manufacturing cost simultaneously.
As improvement, described tooth bar is connected on the moving platen, is meant on the described moving platen to be connected with oil cylinder, and the piston rod of oil cylinder is connected with tooth bar, and described oil cylinder and tooth bar all are horizontally disposed with.After adopting this structure, make the structure of mould whirligig simpler, it is more steady to move.
As further improvement, described alignment pin and rotary turnplate are slidingly matched, and are meant that described rotary turnplate is provided with semi-circular grooves near the one side on the big plane of moving platen, and described alignment pin and semi-circular grooves are slidingly matched.After adopting this structure, make the rotational positioning of rotary turnplate between two secondary moulds more accurate, more convenient.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
By Fig. 1, the mould rotary device structure schematic diagram of the clear double coloured plastic injection machine of the utility model shown in Figure 2 as can be known, the mould whirligig of clear double coloured plastic injection machine, comprise rotating shaft 7, rotary turnplate 6, alignment pin 3, described rotary turnplate 6 is rotatably connected on the moving platen 2 by rotating shaft 7, described alignment pin 3 and moving platen 2 tight fits, one end of described rotating shaft 7 and rotary turnplate 6 tight fits, the other end is provided with rack and pinion drive mechanism, described gear 1 is a tight fit in the rotating shaft 7, described tooth bar 8 is connected on the moving platen 2, and described alignment pin 3 is slidingly matched with rotary turnplate 6.Described tooth bar 8 is connected on the moving platen 2, is meant on the described moving platen 2 to be connected with oil cylinder 11, and the piston rod 10 of oil cylinder 11 is connected with tooth bar 8, and described oil cylinder 11 and tooth bar 8 all are horizontally disposed with.Described alignment pin 3 is slidingly matched with rotary turnplate 6, is meant that described rotary turnplate 6 is provided with semi-circular grooves 9 near the one side on moving platen 2 big planes, and described alignment pin 3 is slidingly matched with semi-circular grooves 9.
When alignment pin 3 is positioned at semi-circular grooves 9 on the rotary turnplate 6 topmost the time, mould I4, mould II5 on this moment rotary turnplate 6 are in symmetric position up and down.When the rodless cavity of oil cylinder 11 be in the fuel feeding state, when rod chamber is in the oil return state, piston under the effect of rodless cavity horizontal thrust together with piston rod 10, tooth bar 8 to direction horizontal movement away from oil cylinder 11, then drive with tooth bar 8 meshed gears 1 and rotate, thereby by rotating shaft 7 driven rotary rotating disks 6 and mould I4 and the equidirectional rotation of mould II5, this moment, alignment pin 3 just slided in semi-circular grooves 9.When the semi-circular grooves on the rotary turnplate 69 bottom be fixed on moving platen 2 on alignment pin 3 when contacting, tooth bar 8, gear 1 have stopped engaged transmission, this moment, mould I4 and mould II5 finished 180 ° rotatablely moving around rotating shaft 7, had realized location swap.
Then moving platen 2, rotary turnplate 6, mould I4, mould II5 under the effect of plastic injection molding machine clamp force be fixed on solid plate on corresponding mould realize that locked mode moves.When mould I4, mould II5 inject respectively finish after, moving platen 2, rotary turnplate 6, mould I4, mould II5 under the effect of injection moulding machine mould open power be fixed on solid plate on corresponding mould separate.Put in place through die sinking, after goods on the mould eject affirmation, the rod chamber of oil cylinder 11 is in the fuel feeding state, rodless cavity is in the oil return state, this moment piston under the effect of rod chamber horizontal thrust together with piston rod 10, tooth bar 8 to direction horizontal movement near oil cylinder 11, then drive with tooth bar 8 meshed gears 1 and rotate, thereby by rotating shaft 7 driven rotary rotating disks 6 and mould I4 and the equidirectional rotation of mould II5, this moment, alignment pin 3 just slided in semi-circular grooves 9.When the semi-circular grooves on the rotary turnplate 69 topmost be fixed on moving platen 2 on alignment pin 3 when contacting, tooth bar 8, gear 1 have stopped engaged transmission, this moment, mould I4 and mould II5 finished 180 ° rotatablely moving around rotating shaft 7, realized location swap, for matched moulds is next time got ready.
