Description
Technical field
The utility model relates to metal working technical areas, and in particular, to one kind pours mold sealing structure.
Background technique
Overlap is also known as overflow edge, burr etc., mostly occurs on the division position of mold, such as the die joint of dynamic model and quiet mould,
The slide fit position of sliding block, the exhausted gap of mold insert, mandril hole etc., overlap is largely due to mold or board clamp force
Failure causes.Metal extra in impression is cast when casting to flow into flash gutters and formed and enclose metal around the one of forging surrounding.This
It is since the closely sealed precision of contact surface between dynamic model and quiet mould is low, doses is excessive, and clout is leaked at weak seal and formed.
In the technical solution that new energy passenger car battery pack is connect with vehicle frame, a kind of scheme is by battery pack and vehicle frame
It is connected by bracket.For lightweight needs, battery pack is usually aluminum profile, and vehicle frame is usually steel structure, battery pack with
Vehicle frame casts bracket connection by aluminium, and bracket is fastened in battery pack and vehicle frame respectively with bolt, nut (or flange nut) again.
For function needs, preset pour of steel nut is cast from aluminum component, but nut is usually cold-heading molding, and dimensional tolerance is larger, when casting
It can not be fitted close with mold, cause that casting nut edge overlap is serious or even threaded hole is blocked phenomenon, in turn result in part
Scrap and increase deflashing process cost.
Utility model content
For the defects in the prior art, the purpose of the utility model is to provide one kind to pour mold sealing structure.
Mold sealing structure is poured according to one kind provided by the utility model, it is fixed that at least two floatings are provided in mold
Position device, the float positioning device includes locating piece and elastic component, and the locating piece is connected to mold by the elastic component
Interior, the shape of the locating piece is adapted with the threaded hole of nut.
Preferably, further including the overlap mould being set to around the float positioning device, the metal in the overlap mould is molten
The bound edge of the liquid working face after molding as the nut.
Preferably, the upper mold and/or lower die of the mold is arranged in the float positioning device and the overlap mould.
Preferably, the overlap mould is trapezoidal.
Preferably, the elastic component includes spring.
Preferably, the locating piece includes positioning pin.
Compared with prior art, the utility model have it is following the utility model has the advantages that
The mold sealing structure that pours of the utility model absorbs nut end face aluminium caused by height of nut difference using elastic component
Liquid leakage problem；Guarantee center, flatness and two and the multiple nut end faces of nut using locating piece positioning action
Between the depth of parallelism, while for subsequent bound edge design lay the groundwork；By the design of overlap mould, amplifies finning, make overlap
The bound edge of working face as nut becomes a part of part assembly, increases nut support face area, prevents by opponent
Part conquassation.In addition, can save deflashing process by the utility model, simplification of flowsheet reduces cost and improves finished product
Qualification rate.
Detailed description of the invention
Upon reading the detailed description of non-limiting embodiments with reference to the following drawings, other spies of the utility model
Sign, objects and advantages will become more apparent upon:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the molding schematic diagram of product structure using the utility model；
Fig. 3 is the molding schematic diagram of product structure using the utility model；
Fig. 4 is the partial enlarged view of molding product.
Specific embodiment
The utility model is described in detail combined with specific embodiments below.Following embodiment will be helpful to this field
Technical staff further understands the utility model, but does not limit the utility model in any form.It should be pointed out that ability
For the those of ordinary skill in domain, without departing from the concept of the premise utility, several changes and improvements can also be made.
These are all within the protection scope of the present invention.
As shown in Figure 1, one kind provided by the utility model pours mold sealing structure, at least two are provided in mold 1
A float positioning device 2, float positioning device 2 include locating piece and elastic component, and locating piece is connected in mold by elastic component,
The shape of locating piece is adapted with the threaded hole of nut.Pouring mold sealing structure further includes being set to around float positioning device
Overlap mould 3, the bound edge of the molten metal working face after molding as nut in overlap mould 3.
Elastic component can be spring, be also possible to other elastic constructions, and locating piece can be positioning pin, be also possible to other
Location structure；In addition, the upper mold and/or lower die of mold 1 is arranged in float positioning device 2 and overlap mould 3, the present invention does not make this
Limitation.
When in use, nut is passed through after locating piece is located on mold 1 respectively, mold clamp is cast.At
Product after type is as shown in Figures 2 to 4.The packet of molten metal two working faces after molding as nut 5 in overlap mould 3
Side makes casting 4 be closely as one with nut 5.Common, overlap mould 3 uses structure trapezium structure, therefore packet after molding
Side is also trapezium structure.The supporting surface area for increasing nut 5 prevents opponent's part to be crushed product.
The mold sealing structure that pours of the utility model absorbs nut end face aluminium caused by height of nut difference using elastic component
Liquid leakage problem；Guarantee center, flatness and two and the multiple nut end faces of nut using locating piece positioning action
Between the depth of parallelism, while for subsequent bound edge design lay the groundwork；By the design of overlap mould, amplifies finning, make overlap
The bound edge of working face as nut becomes a part of part assembly, increases nut support face area, prevents by opponent
Part conquassation.In addition, can save deflashing process by the utility model, simplification of flowsheet reduces cost and improves finished product
Qualification rate.
Leakage causes product bad caused by part is unable to close fit with mold when avoiding casting, we courageously set
Think, amplify finning, so that overlap is become a part of part assembly, mass defect is made to become product design characteristic.
In the description of the present application, it is to be understood that term " on ", "front", "rear", "left", "right", " is erected at "lower"
Directly ", the orientation or positional relationship of the instructions such as "horizontal", "top", "bottom", "inner", "outside" is orientation based on the figure or position
