Chinese patent Granted publication number: CN202088334U on December 28 2011 Granted publication day, discloses a kind of die positioning structure; Include two templates, be fixed with locating piece in the said template, be provided with mesopore in the said locating piece; In mesopore, be provided with fixture block; Said fixture block and mesopore size are complementary, and fixture block is provided with projection, are provided with spring between fixture block and the template; Be provided with spacing clamp in another template, said spacing clamp be provided with fixture block on the corresponding limited block of projection.The location structure of this utility model is to be used for two templates are positioned.Therefore, the weak point of this utility model is that function singleness can not be used for die sleeve and mould pin are positioned.
The utility model content
The utility model is the deficiency for the function singleness that overcomes die casting of the prior art, provide a kind of can be with the location structure of mould pin and the pinpoint die casting of die sleeve.
To achieve these goals, the utility model adopts following technical scheme:
A kind of location structure of die casting; Said mould comprises lower die-sleeve and mould pin; Location structure and syndeton are located between lower die-sleeve and the mould pin, and said location structure comprises cylindrical locating piece and bolt, match with lower die-sleeve in locating piece top; In the locating piece, the bottom matches with the mould pin, bolt is located on the mould pin; Be provided with the bolt hole of lower ending opening in the locating piece, bolt top is stretched into bolt hole and is connected with locating piece.
The location structure of the utility model can accurately be located lower die-sleeve and mould pin, and syndeton is fixedly connected lower die-sleeve with the mould pin; And location structure be arranged so that the follow-up operation that connects with syndeton become simply, quick.
Syndeton is made up of several connecting bolts of uniformly-spaced arranging of being located between die sleeve and the mould pin.The length of connecting bolt is 140 millimeters to 250 millimeters.
The utility model has effectively overcome in the die casting engineering, and between mould pin and the die sleeve squint easily in the position, the problem that causes mould and press to damage.
The operating process that lower die-sleeve and mould pin are located by connecting comprises the steps:
At first, the locating piece in the location structure is connected with bolt fixing;
Then, locating piece is put into the locating hole of lower die-sleeve, accurately locate the position between lower die-sleeve and the mould pin;
At last, with syndeton lower die-sleeve is fixedly connected with the mould pin.
As preferably, the edge of said locating piece is provided with annular chamfer.Annular chamfer is more prone to the compounding practice of locating piece and lower die-sleeve and mould pin.
As preferably, the top, side of said locating piece tilts to the axle center of locating piece, and the top, side of locating piece and the angle between the vertical guide are that 0.5 degree is to 3 degree.Being arranged so that locating piece cooperates with lower die-sleeve and being more prone to of this structure.
As preferably, the diameter of said locating piece is 40 millimeters to 60 millimeters, and the height of locating piece is 30 millimeters to 50 millimeters.
As preferably, the length of said bolt is 180 millimeters to 290 millimeters, and the diameter of bolt is 20 millimeters to 36 millimeters.
As preferably, the fit clearance between locating piece and the lower die-sleeve is 0.03 millimeter to 0.05 millimeter.The qualification of the size of fit clearance has improved the positioning accuracy between locating piece and the lower die-sleeve.
As preferably, the fit clearance between locating piece and the mould pin is 0.03 millimeter to 0.05 millimeter.The qualification of the size of fit clearance has improved the positioning accuracy between locating piece and the mould pin.
Therefore, the utlity model has following beneficial effect:
(1) location structure be arranged so that the follow-up operation that connects with syndeton become simply, quick;
(2) positioning accuracy is high between die sleeve and the mould pin, has effectively overcome in the die casting engineering, and between mould pin and the die sleeve squint easily in the position, the problem that causes mould and press to damage.
