The specific embodiment
Like Fig. 1, shown in Figure 2; The middle template die dish tumbler that provides by the utility model; Comprise mould pressing plate 1, mould 2, middle plate 3, axle sleeve 4, rotating shaft 5, gland 6, mould location steel bushing 7, positional cylinder 8, oil motor 9, mould pinion 10, mould near sensor block 11, mould is near installation sleeve 12, mould locating piece 13 and mould position block 14.Mould wherein is installed on the mould 2 to rotate in axle sleeve 4 with mould locating piece 13 and with rotating shaft 5 near sensor block 11; Axle sleeve 4 is glanded 6 and is fixed on the middle plate 3; On the middle plate 3 mould position block 14 is installed; Be equipped with near sensitive switch at mould, the second cover mould also be installed on mould pressing plate 1, can play spacing and the security protection effect near installation sleeve 1.2 and sensitive switch near installation sleeve 12.During work; The mould pinion is installed on the oil motor 9 through oil circuit and electrical equipment control and drives mould 2 and gyroaxis 5 rotates with fast speeds axle sleeve 4 in, rotate to a position after, the sensitive switch in the installation sleeve 12 is touched the generation transducing signals by mould near sensor block 11; The rotating speed of control oil motor 9 slows down; Thereby mould 2 is put in place with slower speed rotation, and when mould continued to forward to the b position, the second cover sensing was touched near sensor block 11 by mould near switch; Produce transducing signal again mould 2 is stopped operating, the mould locating piece 13 that is arranged on simultaneously on the mould 2 is adjacent to mould position block 14 on the middle plate mutually.Malfunctioning in order to prevent sensitive switch, the utility model is provided with the nearly gauge tap of two windings and one group of mechanical positioner altogether, the nearly gauge tap of every winding be two near switch; Make mould elder generation fast rotational; Become at a slow speed during approaching putting in place,, when it rotates, can produce very big inertia force because the weight after installing mould on the mould is very big; If rotary speed is too fast; The one, be difficult for making it to stop in position accurately, the 2nd, can bring very big impulsive force to spacing part, reduce the service life of part; If adopt (prerequisite is that speed must be reduced to enough slowly) at a slow speed, can address the above problem, but increase the time that the mould rotation replaces, reduce production efficiency.For preventing that the utility model also is designed with positional cylinder 8 because of locating inaccurate mold damage, after mould 2 stopped operating, positional cylinder 8 produced action simultaneously, and the alignment pin of positional cylinder 8 inserts in the steel bushing 7 of mould location mould 2 is accurately located.In like manner, when reverse rotation, following two near switch and mould position block 14 work mould 2 is put in place after, the alignment pin of positional cylinder 8 inserts in the steel bushing 7 of mould location mould is accurately located.
Realization mould speed change can be controlled through oil circuit and realize that its oil channel structures is as shown in Figure 2, when clockwise rotating; Coil S2 gets electric, position, a reversal valve V break-in left side, and motor M1 drives variable pump P process reversal valve V to revolving die oil motor M2 fuel feeding; Thereby make oil motor M2 fast turn-around drive mould 2 motion clockwise fast, when mould 2 forwarded first near the position of switch near sensor block 11, first produced a signal to the PLC (not shown) near switch; Signal of PLC (not shown) feedback slows down motor M1 rotating speed, thereby the rotating speed of revolving die oil motor M2 is slowed down to motor M1 place; When mould 2 forwards second position near switch near sensor block 11; Second produces a signal to the PLC (not shown) near switch, and signal of PLC feedback makes coil S2 dead electricity to reversal valve V place; Thereby make reversal valve V to meta, revolving die oil motor M2 stops operating.When counterclockwise rotating, situation is opposite.
As shown in Figure 6, two injection members 15 and 16 are housed on double-colored machine, their arranged verticals have independently melten gel screw device, can select different plasticizing process conditions for use according to material character.Connecting the rotating disk 2 that has punch 17 on the middle plate 3 of clamping mechanism.Injection is carried out as follows: during A, a kind of melt of color injects die cavity in the position, and after the cooling die sinking, oil motor 9 rotates through gear driven rotating disk 2, and semi-finished product are turned to position B together with punch, and the die of position B is darker, makes die cavity that bigger volume arranged.In this die cavity, inject the melt of second kind of color, form the plastic products of two clear looks.
As required, the transmission device of the utility model can be rotated through gear & rack structure drive mould by oil cylinder and replace present oil motor directly to drive the structure that mould rotates.
