Abstract

The invention discloses a kind of casting die, including movable floor, urceolus, inner core, casting pressing port and die main body, described casting pressing port is fixed on the top of die main body, described movable floor is positioned at the bottom of described die main body, within inner core is wrapped in by described urceolus, in described urceolus, setting direction is perpendicular to two guiding gutters of movable floor, and arranges upper and lower two through holes at the sidewall of described urceolus, and said two through hole is each passed through the sidewall of described urceolus and is connected with guiding gutter.Described casting pressing port is tubular structure, and internal cavity is rounding bench-type cavity, and the opening at the opening that in described rounding bench-type cavity, diameter is less and inner core top matches, it is simple in casting pressing port, injection liquid is to inner core.Present configuration is simple, and before efficiently solving, mould structure makes foundry goods produce the problem of transverse grain boundaries, and the casting quality of production is reliable, stable performance.

Description

A kind of casting die
[technical field]
The present invention relates to machine die technical field, particularly to a kind of casting die.
[background technology]
The grain coarsening of traditional casting die casting, easily makes foundry goods produce transverse grain boundaries, have impact on the physics of foundry goods Performance and mechanical performance.Preferably cast structure is to have uniform, tiny equiax crystal on the whole cross section of foundry goods, this is because etc. Axialite anisotropy is little, and during processing, deformation is uniform, excellent performance, plasticity are good, is beneficial to casting and plastic working subsequently, existing Casting die structure is typically relatively inaccessible to this level.
[summary of the invention]
In view of this, for overcoming the deficiencies in the prior art, the present invention provides a kind of casting die, solves in prior art The problem of casting die casting crystal grain coarse language, the guiding gutter arranged by inside, is injected cooling water and foundry goods is carried out lasting determining To solidification, cooling, product is made not produce transverse grain boundaries.
For achieving the above object, technical scheme is as follows:
A kind of casting die, including movable floor, urceolus, inner core, casting pressing port and die main body, described casting pressing port is solid Being scheduled on the top of die main body, described movable floor is positioned at the bottom of described die main body, and inner core is wrapped in it by described urceolus In, in described urceolus, setting direction is perpendicular to two guiding gutters of movable floor, and arranges upper and lower two at the sidewall of described urceolus Individual through hole, said two through hole is each passed through the sidewall of described urceolus and is connected with guiding gutter.
Further, described casting pressing port is tubular structure, and internal cavity is rounding bench-type cavity, and described inverted round stage The opening that in type cavity, diameter is less matches with the opening at inner core top.
In casting die cooling procedure, this inverted circular platform type cavity structure, be conducive to from casting pressing port along sky Cavity wall adds liquid, flows slowly into inner core and former liquid is carried out feeding, prevent shrinkage cavity phenomenon.
The upper surface of described movable floor is horizontal plane, seals mutually with the bottom of described inner core and welds.
Making it is also preferred that the left described casting pressing port is filled sand mold by thick walled steel tube, stabilized structure, casting pressing port is use in casting mold In the cavity of storage molten metal, feed metal when foundry goods is formed, have and prevent shrinkage cavity and porosity, aerofluxus and the effect of collection slag.
The invention has the beneficial effects as follows, simple in construction, design ingenious that the guiding gutter arranged by inside injects cooling water Foundry goods is carried out lasting directional solidification, cooling, makes product not produce transverse grain boundaries, efficiently solve and prior art is watered mold The problem of tool casting crystal grain coarse language.
[accompanying drawing explanation]
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing In having technology to describe, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only this Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to Other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the present invention.
In figure, 1, movable floor, 2, urceolus, 3, inner core, 4, casting pressing port, 5, through hole, 6, guiding gutter, 7, through hole, 8, mould Tool main body.
[detailed description of the invention]
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise Embodiment, broadly falls into the scope of protection of the invention.
With reference to Fig. 1, a kind of casting die, including movable floor 1, urceolus 2, inner core 3, casting pressing port 4 and die main body 8, Within inner core 3 is wrapped in by urceolus 2, two guiding gutters 6 being perpendicular to movable floor 1 are set in urceolus 2, and in the side of urceolus 2 Portion arranges upper and lower two through holes 5,7, and described through hole 5 is each passed through urceolus 2 sidewall and connects with guiding gutter 6 with through hole 7.
Movable floor 1 is positioned at the bottom of die main body 8, is used for the sealed bottom of the inner core 3 in die main body 8, simultaneously Die main body 8 is fixed.
The upper surface of movable floor 1 is horizontal plane, and by the way of welding, the bottom with inner core 3 seals mutually.
Casting pressing port 4 is fixed on the top of die main body 8, and casting pressing port 4 is tubular structure, the sky within casting pressing port 4 Chamber is rounding bench-type cavity, and the opening at the opening that in described rounding bench-type cavity, diameter is less and inner core 3 top matches.
Casting pressing port 4 is filled sand mold by thick walled steel tube and is made, stabilized structure, and casting pressing port 4 is that casting mold is interior for storing gold Belong to the cavity of liquid, feed metal when foundry goods is formed, have and prevent shrinkage cavity and porosity, aerofluxus and the effect of collection slag.
During the use of casting die, the opening from casting pressing port 4 upper end injects liquid, arrives bottom inner core 3, with Time uniform temperature the cooling through hole 5 that starts from top of water inject, flow along guiding gutter 6 water conservancy diversion direction, through hole 7 from below flows Going out, foundry goods is oriented cooling, during cooling, the liquid in inner core 3 can produce volume and size reduces phenomenon, this Time casting pressing port 4 liquid can be carried out feeding, be effectively prevented the phenomenons such as shrinkage cavity, improve quality and the performance of foundry goods.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention Within god and principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
