The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Shown in Fig. 2-1,2-2,3-1 and 3-2, the mould structure of the double-colored wheel of the utility model comprises front mould and back mould, and front mould and mould middle part, back are core rod 14 and die cavity 13.Wherein front mould comprises runner plate, A plate 3 and is arranged on slide block 2 on the A plate 3, back mould is made up of B plate 4, B plate supporting plate 5, base plate 7 and liftout attachment 6, be provided with hot mouth 10 in the described front mould, run through between described A plate 3 and the B plate 4 and be provided with guide shaft, be fixed with button crucian carp 8 on the described B plate 4, B plate supporting plate 5 is provided with and produces base 15 and slide block guide post 1.Be added with caging bolt 11 in the middle of described B plate and the B plate supporting plate.Guide shaft is fixed between A plate and four holes of B plate, runs through a whole set of mould, because guide shaft moves, so the centre is provided with guide pin bushing.Described slide block guide post and product base are fixed on the B plate supporting plate, and described slide block is placed on the A plate by briquetting, and described button crucian carp is fixed on the B plate, and effect is exactly to guarantee in the process of mould die sinking, and mould is opened B plate supporting plate earlier, and then opens A, B plate.

Shown in Fig. 2-1,2-2,3-1,3-2,5-1 and 5-2, mould structure of the present utility model is the double-color mold of four products of one one mould, 8 slide blocks of front mould, in establish sliding block spring 9, be provided with hot mouth 10 in the front mould, then mould is made up of B plate 4, B plate supporting plate 5, base plate 7, liftout attachment 6, producing base 15 is fixed on the B plate supporting plate 5, slide block guide post 1 is fixed on and produces on the base 15, and the centre is provided with spring 12 and guarantees that the B plate can flick smoothly, and spring 12 is between B plate and B plate supporting plate.

As shown in Figure 4, the crucian carp of buckleing of the utility model mould is fixed on the B plate, and hook and the push rod of button crucian carp 8 are separately fixed on A plate 3 and the B plate supporting plate 5.

It shown in Fig. 1-1a, 1-2a the product schematic diagram of the mould structure of the double-colored wheel of the utility model.

The course of work of the utility model double-color mold is as follows: when mould closes when touching, slide block guide post 1 drives slide block 2 and advances, the wear-resistant block that produces on the base 15 kills slide block, at this moment, product can carry out injection moulding, after injection moulding is finished, the mould die sinking, slide block guide post 1 drives slide block 2 motions, sliding block spring 9 limits slide block 2, slide block 2 moves forward owing to inertia, and sliding block spring 9 plays spacing effect, and because the effect of button crucian carp 8, because hook fastens crucian carp, so A, spring 12 effects between B plate and the B plate supporting plate are added in the not die sinking earlier of B plate, so B plate and B plate supporting plate are opened earlier, when B plate and B plate supporting plate reach certain stroke, push rod promotes the mold insert of button crucian carp the inside, and hook is inoperative, so A, the die sinking of B plate.Because caging bolt 11 is arranged, so B plate and B plate supporting plate stroke stop to certain distance, after the mould die sinking, because the effect of liftout attachment, product comes off automatically.

The utility model mould adopts twice-die-opening and is in back mould one side; producing that base and guide pillar be fixed on the B plate supporting plate and detain crucian carp must be to allow B plate and B plate supporting plate open earlier; A then; the B plate is opened; be to drive the front mould slide block movement when being die sinking; preceding mode slider is fixed on the front mould by compact heap; slide block is the sealing position at front mould, and flexible glue is by the slide block sealing, because the slide block of mould is located at front mould; and mould itself is provided with hot mouth; so mould slide block guide pillar; produce base and stay on the B plate supporting plate, when the mould matched moulds, slide block guide post passes slide block; producing base kills slide block; product carries out injection moulding, when the mould die sinking, because the effect of button crucian carp; B plate and the die sinking of B plate supporting plate elder generation; thereby produce base and slide block guide post motion, and the motion of producing base and slide block guide post has driven the motion of slide block, and slide block retreats.When supporting plate die sinking certain distance, the button crucian carp opens, because caging bolt is arranged, and A, the die sinking of B plate, the thimble of liftout attachment ejects.

The mould structure of the double-colored wheel of the utility model is simple, safe and reliable, not only makes things convenient for full-automatic operation in the injection moulding process, and has saved raw material, has reduced cost.
