Description
Technical field
The utility model relates to a kind of compression mod oblique core drawing mechanism, belongs to die casting field.
Background technology
Have in some die castings and have and die joint off plumb two inclined holes, this inclined hole, core rheo-die-casting can not be set and this two holes at dynamic, cover half.Due to diecasting alloys liquid shrink from high temperature coagulation time, there will be shrinkage cavity at the heavy wall position of foundry goods.If these two holes do not have die casting out but entity, the foundry goods of die casting has shrinkage cavity defect in the entity inside of hole site, causes foundry goods defective.
Two inclined holes of this kind of foundry goods, can not use normal core to cast out the inclined hole of foundry goods at dynamic model or cover half side; In die joint or dynamic model side, can directly use slide block, device of loosing core looses core, and inner because there is no enough spaces at cover half side die cavity, can not directly use slide block, device of loosing core looses core.
Utility model content
The purpose of this utility model is to provide a kind of compression mod oblique core drawing mechanism, to solve the problem.
The utility model have employed following technical scheme:
A kind of compression mod oblique core drawing mechanism, it is characterized in that having: at least one tiltedly takes out core, is predetermined angular with the die joint of mould; At least one slide plate of loosing core, and tiltedly takes out core and matches, and with tiltedly take out core and be fixedly connected with, slide plate of loosing core also has slide guide hole; At least one curved guide pillar, curved guide pillar is arranged in slide guide hole; Loose core oil cylinder, be connected with curved guide pillar, the curved guide pillar of push-and-pull on the direction parallel with die joint, the angle between the axis of curved guide pillar and oil cylinder of loosing core is obtuse angle.
Further, compression mod oblique core drawing mechanism of the present utility model, can also have such feature, also comprise: slide block, is arranged on after curved guide pillar.
Further, compression mod oblique core drawing mechanism of the present utility model, can also have such feature, also comprise: I-shaped joint, is arranged on after slide block.
Further, compression mod oblique core drawing mechanism of the present utility model, can also have such feature, also comprise: connection watt, is connected to after I-shaped joint.
Further, compression mod oblique core drawing mechanism of the present utility model, can also have such feature, also comprise: oil cylinder of loosing core, be connected to connect watt after.
The beneficial effect of utility model
According to compression mod oblique core drawing mechanism of the present utility model, tiltedly take out core owing to have employed, loose core slide plate and curved guide pillar, and curved guide pillar can move along the slide guide hole of slide plate of loosing core, when pulling curved guide pillar, by the power of the left and right directions to distortion guide pillar, be converted into the power of the axis along inclined hole to slide plate of loosing core, thus extract out tiltedly taking out core from mould in a limited space.
Accompanying drawing explanation
Fig. 1 is the structural representation that compression mod oblique core drawing mechanism uses in a mold.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1, compression mod oblique core drawing mechanism has first and tiltedly takes out core 11, and second tiltedly takes out core 12, first looses core slide plate 13, second looses core slide plate 14, the curved guide pillar 16 of the first curved guide pillar 15, second, slide block 18, I-shaped joint 19, connect watts 20, the compositions such as oil cylinder 21 of loosing core.
Present embodiment is to manufacture the mould with two inclined holes, therefore there are two and tiltedly take out core, namely, first tiltedly take out core 11 and second and tiltedly take out core 12, these two angles tiltedly taken out between core and the die joint of mould can need to arrange according to part, are set to 75 ° in the present embodiment.
First slide plate 13 and second slide plate 14 of loosing core of loosing core tiltedly is taken out core 11 and second respectively and is tiltedly taken out core 12 and be connected with first.First slide plate 13 and first of loosing core tiltedly takes out core, and second tiltedly takes out core and second looses core together with slide plate 14 screw fastening, together with time motion.First slide plate 13 and second slide plate 14 of loosing core of loosing core has slide guide hole, respectively for installing curved guide pillar.
First curved guide pillar 15 and the second curved guide pillar 16 tilt certain angle, are arranged on the first slide plate 13 and second of loosing core and loose core in the slide guide hole of slide plate 14.
Slide block 18 and the first curved guide pillar 15 and the second curved guide pillar 16 are with together with screw fastening.During assembling, the first curved guide pillar 15 and the second curved guide pillar 16 have injected in advance looses core in the slide guide hole of slide plate.
Loose core and slide plate has the structure of slide guide hole, curved guide pillar is limited in slide guide hole and slides, simultaneously, curved guide pillar becomes obtuse angle with the central axis direction of oil cylinder 21 of loosing core, therefore when curved guide pillar is subject to the power of horizontal direction, owing to loosing core slide plate and tiltedly take out core and be limited in the horizontal direction in a mold, the effect that slide plate of therefore loosing core is subject to the tangential force of curved guide pillar along the axially-movable of self, thus can only be extracted by from mould.
Cover half cage plate 17 and fixed die insert 7 are the structures on mould.
I-shaped joint 19, connect watts 20 and oil cylinder 21 of loosing core be successively set on after slide block 18.
To loose core action: when loosing core, the piston driving piston rod of oil cylinder 21 of loosing core does the action of loosing core, piston rod is by connecting watts 20 and I-shaped joint 19, and band movable slider 18 and the first curved guide pillar 15 move (namely moving right to the position shown in Fig. 1) with the second curved guide pillar 16 outside the direction parallel with die casting die joint; The curved guide pillar 16 of first curved guide pillar 15, second utilizes its elbow, drives first tiltedly to take out core 11, second and tiltedly takes out core 12, first and to loose core slide plate 13, and the second slide plate 14 of loosing core outwards moves in the core fixing hole of fixed die insert, extracts oblique core out.
Lock pin action: during lock pin, the piston driving piston rod of oil cylinder 21 of loosing core does the action of lock pin, piston rod is by connecting watts 20 and I-shaped joint 19, promotion slide block 18 and the curved guide pillar 16 of the first curved guide pillar 15, second move (namely to the position shown in Fig. 1 to left movement) inwards along the direction parallel with die casting die joint; The curved guide pillar 16 of first curved guide pillar 15, second utilizes its elbow, promote to loose core slide plate and tiltedly core in the core fixing hole of fixed die insert, do lock pin motion, insert oblique core.Curved deformation during in order to prevent lock pin, affects the positional precision that oblique core inserts, and time after inserting, cover half cage plate 17 will be close in the head inclined-plane of curved guide pillar.
Different from mould, mould of the present utility model has oblique core drawing mechanism in cover half side, oblique extraction core in the past.It is more ingenious that compression mod oblique core drawing mechanism of the present utility model designs, and the precision comparison of manufacture is high, stable movement during use, reliable in action, and the life-span is long, uses no abnormality seen situation to occur at press casting procedure.The quality of die casting produced is qualified, and steady quality.
