Abstract
A consumable casting mould is composed of main body and sprue gate and is made up of styrene foam by negative-pressure suction moulding. Said styrene foam has low residual dreg ratio (one 3000th) and low fusion temp (less than 250 deg.C).
Description
Affiliated technical field
The present invention relates to a kind of mould that metal casting is used, especially a kind of vanish mould for casting polystyrene foam.
Background technology
At present, the casting of metal adopts wooden mould to do founding, during its foundry practice, generally need operations such as molding, founding, the demoulding and mould assembling, not only technology is loaded down with trivial details, complicated for this operation, the technology operation easier is big, and take a lot of work, time-consuming, its castability also can not get good guarantee, though technologies such as some paraffin castings are also arranged, the founding ratio is easier to, many because wax-pattern weight is big, intensity is low, be not easy to make, carry and operation,, also do not have good solution at present this.
Summary of the invention
In order to overcome the shortcoming in the metal current casting, the invention provides a kind of vanish mould for casting polystyrene foam, use this die operation, make operation simple, convenient, super quality and competitive price, saving of work and time, can reach the hot investment casting requirement fully, and this mould is extremely light, be easy to carry especially transportation and Job Operations, and this mould has great economy and promotional value.
The present invention solves the concrete scheme that its technical problem adopts: this mould comprises gating pattern (3) and die body (4) two parts; It is characterized in that: (1) this mould is made by styrofoam negative pressure plastic uptake, and this moulding process can make the die body after the moulding enrich complete bright and clean; (2) the forming moulding bed of this foam mould made for aluminum alloy materials, and it is easy to process, and is economical and practical; (3) foamed plastic of this mould selects for use the residue ratio smaller or equal to 1/3000th, and melting temperature is lower than 250 ℃ special-purpose styrofoam.
Its beneficial effect is: use this die operation operation not only extremely simple, convenient, super quality and competitive price, saving of work and time, can reach the hot investment casting requirement fully, and this mould is extremely light, be easy to carry especially transportation and Job Operations, and this mould has great economy and promotional value.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples;
Accompanying drawing is a structural representation of the present invention;
Among the figure, 1 casting case, 2 molding sand, 3 gating patterns, 4 die bodys.
Specific embodiment
The operation principle of this mould is: die body (4) is imbedded the interior compacting of casting case (1), and the last plane of gating pattern (3) is concordant with the molding sand upper surface in the casting case, during casting, directly the molten iron of fusing is aligned gating pattern (3), and direct pouring gets final product; At this moment, gating pattern (3) and die body (4) fusing rapidly become gaseous volatilization, and molten iron flows in the space that die body (4) is occupied in the molding sand in proper order, treats promptly to may be molded to casting body after molten iron is full of.
In the drawings, the molding sand (2) in the casting case (1) is the same with conventional molding sand, does not have any variation, and the granularity of molding sand (2) requires to determine that the high granularity requirements of precision is thinner according to the molding sand of essence casting.
In the drawings, gating pattern (3) is up big and down small funnel shaped, and its underpart and die body (4) are connected, and this mould can be with die body (4) moulding, also can make separately, is same material.
Claims (2)
1 vanish mould for casting polystyrene foam, this mould comprise gating pattern (3) and die body (4) two parts; It is characterized in that: (1) this mould is made by styrofoam negative pressure plastic uptake, and this moulding process can make the die body after the moulding enrich complete bright and clean; (2), the forming moulding bed of this foam mould make for aluminum alloy materials, it is easy to process, and is economical and practical; (3) foamed plastic of this mould selects for use the residue ratio smaller or equal to 1/3000th, and melting temperature is lower than 250 ℃ special-purpose styrofoam.
2 vanish mould for casting polystyrene foam according to claim 1 is characterized in that: gating pattern (3) is up big and down small funnel shaped, and its underpart and die body (4) are connected.
