Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: see Fig. 2, Fig. 3, a kind of aluminium alloy guide pin bushing die casting, comprises dynamic model and cover half, and described dynamic model comprises moving clamping plate 1, dynamic model cage plate 2, moving die insert 3 and punch 4, and described cover half comprises fixed clamping plate 5, cover half cage plate 6 and fixed die insert 7.Accurate in order to ensure the contraposition of dynamic model cage plate 2 and cover half cage plate 6, dynamic model cage plate 2 is connected by guidance set with cover half cage plate 6, described guidance set comprises straight guide pin bushing, straight guide pillar, straight guide pin bushing is fixedly arranged on dynamic model cage plate 2, to insert in described straight guide pin bushing and the straight guide pillar that can slide along straight guide pin bushing is installed on cover half cage plate 6.
Described punch 4 one end has limited step, and moving die insert 3 is provided with Scalar male die 4 locating hole, and this punch 4 is fixed with coordinating of dynamic model cage plate 2 by moving die insert 3 after this punch 4 locating hole passes away from one end of limited step.The position that described fixed die insert 7 is corresponding with punch 4 has a die, and when dynamic model and cover half matched moulds, punch 4 inserts in this die away from one end of limited step, and forms die cavity between punch 4 and circular groove.During concrete enforcement, moving die insert 3 is fixedly connected with cover half cage plate 6 with dynamic model cage plate 2 respectively by bolt with fixed die insert 7; Like this, after punch 4 or die damage, maintenance, the replacing of punch 4 can be realized by dismounting moving die insert 3 and fixed die insert 7, and the reparation of moving die insert 3 and fixed die insert 7 or replacing, thus make maintenance, change more convenient, and maintenance cost is lower.During concrete enforcement, described moving die insert 3, punch 4 are many groups with fixed die insert 7, and as a kind of embodiment, its group number is 10 groups, thus can realize a mould 10 die casting simultaneously, thus promotes die casting efficiency further, improves production efficiency.
Be provided with the first pouring basin at moving die insert 3 near the side of fixed die insert 7, fixed die insert 7 is provided with the second pouring basin near the side of moving die insert 3, and described first pouring basin and the second pouring basin partly overlap; The degree of depth of described second pouring basin near one end of die cavity reduces gradually, and is connected with die; When after dynamic model and cover half matched moulds, the first pouring basin forms with the second pouring basin the ingate be connected.
Moving die insert 3 is provided with a spreader 8, and described spreader 8 is in column, and it is interior and fixing with moving die insert 3 that its one end embeds moving die insert 3, and the other end stretches in the first pouring basin, and the one end stretching into the first pouring basin is tapered.Water conservancy diversion can be played by spreader 8 and reduce metal liquid to the erosion effect of punch 4 profile, and filling pressure can be increased, thus making cast better effects if, can better die cavity be filled up; Thus make the compactness of product better, improve the die casting quality of product.Cover half is provided with sprue bush 16, and described sprue bush 16 is through fixed clamping plate 5, cover half cage plate 6 fixing with fixed clamping plate 5 and cover half cage plate 6; After dynamic model and cover half matched moulds, the inlet of ingate is connected with this sprue bush 16.
Fixed die insert 7 is provided with a steam vent 9, and one end of described steam vent 9 is connected with die, and the other end runs through fixed die insert 7; To being provided with sealing column 10 by steam vent 9 on punch 4, when dynamic model and cover half matched moulds, described sealing column 10 can be inserted in steam vent 9, and is closed by steam vent 9.Like this, in matched moulds process, the air in die can be discharged from steam vent 9, thus air impacts Forming Quality in minimizing die, increase the compactness of product further, improve the quality of products, meanwhile, when there being a small amount of metal liquid stream hand-hole to solidify, through hole is convenient to cleaning.
Two cushion block 11, two cushion blocks 11 are provided with respectively near the both sides of moving clamping plate 1 and dynamic model cage plate 2 between moving clamping plate 1 and dynamic model cage plate 2; Between two cushion blocks 11, be provided with an ejector pin retaining plate 12, ejector pin retaining plate 12 is provided with push rod 13 and release link 14, one end of described push rod 13 is connected with ejector pin retaining plate 12, and the other end is through dynamic model cage plate 2 and moving die insert 3; During concrete enforcement, push rod 13 is many, and is distributed in punch 4 around; The two ends of described release link 14 are connected with ejector pin retaining plate 12 with dynamic model cage plate 2 respectively.When dynamic model and cover half matched moulds, push rod 13 all protrudes from moving die insert 30.1-0.2mm away from one end of ejector pin retaining plate 12, thus can reduce following process, to enhance productivity; Fast the product of die cast can be ejected from punch 4 in the process of die sinking by push rod 13, thus make speed of production faster.
Moving clamping plate 1 is also provided with stop screw 15, and described stop screw 15 is at least 2, can avoid in the process of die sinking, and moving clamping plate 1 and ejector pin retaining plate 12 direct collision, damage moving clamping plate 1 and ejector pin retaining plate 12.And when dynamic model and cover half matched moulds, can the position of regulating pushing rod fixed head 12 by this stop screw 15.
In the course of work, carried out the cast of molten aluminium alloy by sprue bush 16 after matched moulds, in the process of die sinking, dynamic model moves towards the direction away from cover half with lathe, when punch 4 and die-cast product are after cover half disengaging, ejector pin retaining plate 12 withstands by through moving clamping plate 1 connecting rod be attached thereto, thus form moving clamping plate 1, dynamic model cage plate 2 continues mobile and ejector pin retaining plate 12 and push rod 13 no longer move, until ejected by product under the effect of push rod 13; When lathe moves towards cover half direction, ejector pin retaining plate 12 resets under the effect of release link 14.
Finally it should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model but not restriction technologies scheme, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present utility model.
