Description
Technical field
The utility model relates to die casting technical field, specifically a kind of Yu Ding mechanism of three-plate type die casting.
Background technology
Due to the particularity of three-plate type die casting, foundry goods sprue must be separated with foundry goods cross gate in die sinking process, and in mold mechanism in the past, the mode adopted is: mould tailgate is pulled by die casting machine, mould tailgate relies on the package power of the foundry goods body in mould tailgate and mould between plate to pull plate in mould again, and in mould, foundry goods sprue and foundry goods cross gate are broken by plate again.This mode, because pulling force transitional function is on foundry goods body, easily makes foundry goods body crack, thus cannot ensure the serviceability of foundry goods.
Utility model content
The utility model, for above-mentioned Problems existing, provides a kind of Yu Ding mechanism of the three-plate type die casting can effectively avoiding foundry goods body to crack.
The utility model for achieving the above object, takes following technical scheme to be achieved:
A kind of Yu Ding mechanism of three-plate type die casting, comprise plate and mould tailgate in die head plate, mould, described die head plate is provided with the die cavity of foundry goods sprue, in described mould, plate is provided with the die cavity of foundry goods cross gate, the die cavity of foundry goods body is provided with between plate and mould tailgate in described mould, described foundry goods sprue top has back-off structure, and the contact surface of described die head plate in the middle part of itself and mould is provided with pre-top component.
Foundry goods sprue is connected with cross gate, has back-off structure on sprue top, and when mould die sinking, sprue can be stuck on die head plate, can not along with the movement of plate in mould and cross gate and break away from moulds head plate.Back-off structure coordinates pre-top component, for separating of foundry goods sprue and cross gate.
Preferably, described pre-top component comprises base, spring, pre-fore-set and fixed screw, and die head plate is provided with through hole, base is fixed on through hole one end by fixed screw, pre-fore-set is arranged in through hole, and pre-fore-set is T-type structure, and spring housing is in the bottom of described T-type structure.
Preferably, described pre-top component is arranged on die head plate top.
Preferably, described pre-top component is some groups.
Preferably, described pre-top component is arranged on surrounding and the middle part of the contact surface of plate in die head plate and mould.
Compared with prior art, the beneficial effects of the utility model are as follows: the utility model adopts Yu Ding mechanism, by pre-top component as chief motivation, the back-off structure on the top of foundry goods sprue can fix sprue, thus foundry goods sprue is separated with foundry goods cross gate, main pulling force no longer transitional function, on foundry goods body, effectively can be avoided foundry goods body to crack, thus ensure that the serviceability of foundry goods.
Accompanying drawing explanation
Fig. 1 is the structure chart of the Yu Ding mechanism of a kind of three-plate type die casting of the present utility model;
Fig. 2 is the structure chart of pre-top component.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
See Fig. 1 ~ 2, a kind of Yu Ding mechanism of three-plate type die casting, comprise plate 2 and mould tailgate 3 in die head plate 1, mould, wherein, die head plate 1 is provided with the die cavity of foundry goods sprue 4, and in mould, plate 2 is provided with the die cavity of foundry goods cross gate 5, is provided with the die cavity of foundry goods body 6 in mould between plate 2 and mould tailgate 3, foundry goods sprue 4 top has back-off structure 7, die head plate 1 in the middle part of itself and mould 2 contact surface be provided with pre-top component 8.
Foundry goods sprue 4 is connected with cross gate 5, has back-off structure 7 on sprue 4 top, and when mould die sinking, sprue 4 can be stuck on die head plate 1, can not along with the movement of plate in mould 2 and cross gate 5 and break away from moulds head plate 1.Back-off structure 7 coordinates pre-top component 8, for separating of foundry goods sprue 4 and cross gate 5.
See Fig. 2, pre-top component 8 comprises base 81, spring 82, pre-fore-set 83 and fixed screw 84, die head plate 1 is provided with through hole 11, base 81 is fixed on through hole 11 one end by fixed screw 84, pre-fore-set 83 is arranged in through hole 11, pre-fore-set 83 is T-type structure, and spring 82 is enclosed within the bottom of described T-type structure.
Pre-top component 8 can arbitrarily be arranged on die head plate 1, and preferably, pre-top component 8 is arranged on die head plate 1 top.Pre-top component 8 can be one, also can be multiple.More preferably, pre-top component 8 is arranged on surrounding and the middle part of the contact surface of plate in die head plate and mould, and the dynamics on so pre-top is larger, ejects better effects if.The concrete quantity of pre-top component 8 is arranged according to actual needs.
After mould matched moulds puts in place, in mould, pre-fore-set 83 is pressed into by plate 2, and pre-fore-set 83 Compress Spring 82, thrust saved by spring 82.
When mould die sinking, mould tailgate 3 is pulled by die casting machine; Spring 82 is replied and is released by pre-fore-set 83, and pre-fore-set 83 promotes plate 2 in mould as main thrust; By the pulling force of plate 2 in the back-off structure 7 on the top of foundry goods sprue 4 and mould, sprue 4 and cross gate 5 are broken.After pre-fore-set 83 is released and put in place, in mould, plate 2 is pulled by mould tailgate 3, continues die sinking, until die sinking puts in place.
The utility model adopts Yu Ding mechanism, when mould is opened, by the restoring force of the pre-top spring of pre-top component as the chief motivation of plate in mould, foundry goods sprue and foundry goods cross gate are carried out breaking being separated, foundry goods body is made no longer to be subject to excessive pulling force, foundry goods body effectively can be avoided to crack, thus ensure that the serviceability of foundry goods.
Only as described above, be only the preferred embodiment of the utility model, when can not limit the scope of the utility model enforcement with this, namely generally according to equivalence change simple done by the content described in the utility model claim and utility model description and modification, all still belong within the utility model claim scope.In addition, summary part and title are only used to the use of auxiliary patent document search, are not used for the interest field of restriction the utility model.
