A kind of hot shaping tool of die casting steel disc
Technical field
This utility model relates to die casting steel disc production field, particularly to a kind of hot shaping tool of die casting steel disc.
Background technology
In prior art, die casting steel disc is usually present metaboly in molding, ejection process, and die casting flat-type steel disc is widely used in modern production, such as, apply on mobile phone magnalium center product.Owing to the planarity requirements of the mobile phone magnalium center plane fitting surface of die casting flat-type steel disc is higher, so be generally required for die cast, eject after die casting steel disc carry out shaping, conventional Training system is to be flattened by upper die and lower die, but existing upper die and lower die are planar structure, after routine plastic, the deformation-recovery of die casting steel disc is big, it is difficult to use.The die casting steel disc of effective and high yield i.e. cannot be gone out by conventional plane shaping tool alignment.
A kind of hot shaping tool of die casting steel disc becomes demand.
Utility model content
The purpose of this utility model is, for the problems referred to above, a kind of hot shaping tool of die casting steel disc is provided, it is simple and reasonable, designs ingenious, by coordinating of arc bump and arc groove, well die casting steel disc can be carried out alignment, after alignment, deformation-recovery is low, and the die casting steel disc yield after alignment is high, it is possible to meet the demand used.
The technical scheme that this utility model is used for achieving the above object is:
A kind of hot shaping tool of die casting steel disc, it includes the upper die and lower die of corresponding setting, the bottom of described upper mold is provided with arc bump, the corresponding described arc bump in the top of described lower mold is provided with arc groove, in this arc groove, this arc-shaped groove bottom prominent is provided with some positioning needles, and on described arc bump, corresponding described positioning needle is provided with and dodges hole.
The centre position, bottom of described upper mold is provided with depression, and described arc bump is arranged in this depression, and the bottom of this upper mold is stretched out at the top of this arc bump.
The corresponding described arc bump of described arc groove is arranged at the crown center position of this lower mold.
Top and the bottom of running through described lower mold are provided with the hole that places with described positioning needle equal number, described positioning needle pass described in place hole and be arranged in this lower mold.
The lower diameter of described positioning needle is more than the top of this positioning needle, and the top of this positioning needle is provided with sphere.
Described positioning needle is two, and these two positioning needles are respectively arranged on the diagonal angle of this described arc groove.
The beneficial effects of the utility model are: it is simple and reasonable for this utility model, designs ingenious, by coordinating of arc bump and arc groove, well die casting steel disc can be carried out alignment, after alignment, deformation-recovery is low, and the die casting steel disc yield after alignment is high, it is possible to meet the demand used.
Below in conjunction with the accompanying drawings with embodiment, this utility model is further illustrated.

Detailed description of the invention
Embodiment: as depicted in figs. 1 and 2, this utility model one hot shaping tool of die casting steel disc, it upper mold 1 including corresponding setting and lower mold 2, the bottom of described upper mold 1 is provided with arc bump 11, the corresponding described arc bump 11 in the top of described lower mold 2 is provided with arc groove 21, being provided with some positioning needles 22 bottom this arc groove 21 prominent in this arc groove 21, on described arc bump 11, corresponding described positioning needle 22 is provided with and dodges hole.
The centre position, bottom of described upper mold 1 is provided with depression 12, and described arc bump 11 is arranged in this depression 12, and the bottom of this upper mold 1 is stretched out at the top of this arc bump 11.
The corresponding described arc bump 11 of described arc groove 21 is arranged at the crown center position of this lower mold 2.
Top and the bottom of running through described lower mold 2 are provided with the hole that places with described positioning needle 22 equal number, described positioning needle 22 pass described in place hole and be arranged in this lower mold 2.
The lower diameter of described positioning needle 22 is more than the top of this positioning needle 22, and the top of this positioning needle 22 is provided with sphere.
Described positioning needle 22 is two, and these two positioning needles 22 are respectively arranged on the diagonal angle of this described arc groove 21.
When in use, the die casting steel disc 3 of deformation is placed in lower mold 2, the epirelief part of this die casting steel disc 3 is just to arc bump 11, and described positioning needle 22 is that the hole, location 31 on corresponding die casting steel disc 3 is arranged, and makes positioning needle 22 be positioned by die casting steel disc 3 through hole 31, location, upper mold is pressed for 1 time, it is thus possible to convex under being divided to become by the upper convex portion of die casting steel disc 3, after die casting steel disc 3 is taken out from lower mold 2, die casting steel disc 3 deformation-recovery, complanation or slight under convex, thus meet and use requirement.
It is simple and reasonable for this utility model, designs ingenious, by coordinating of arc bump 11 and arc groove 21, it is possible to well die casting steel disc 3 being carried out alignment, after alignment, deformation-recovery is low, and die casting steel disc 3 yield after alignment is high, it is possible to meet the demand used.
As described in this utility model embodiment, other hot shaping tools of die casting steel disc of structure same or similar with this utility model, all in this utility model protection domain.
