Description
Technical field
The utility model relates to a kind of silica gel mould that accelerates to cool off, and is used for improving the silica gel mould thermal diffusivity, belongs to non-ferrous metal silica gel mould centrifugal casting field.
Background technology
The process of setting of metal is the generation of nucleus and the growth process of nucleus, and these two processes are carried out simultaneously.In the limited time and space, it is more many that nucleus produces, and what crystal grain will be all the more is tiny, and the degree of refinement of crystal grain directly has influence on plasticity and the toughness of foundry goods.Degree of supercooling is to influence liquid phase to the decisive factor of the phase driving force of solid transformation, and degree of supercooling is more big, and it is just more big to solidify phase driving force, thereby nucleation rate is just more high.Therefore, increasing the degree of supercooling of melt, is crystal grain thinning, the effective way of raising casting quality.
Usually be attached to forming core on the external surface of solids in the liquid during actual metal crystallization, this forming core mode is called heterogeneous nucleation.Minute impurities in the external surface of solids and the melt can be used as the substrate of heterogeneous nucleation, and the quantity of forming core substrate has determined the quantity of forming core.For the heterogeneous nucleation process, the contact angle of separating out solid phase and external particle is the most critical factor that determines forming core speed.Therefore, when the forming core substrate surface is uneven, forming core efficient will improve when having a large amount of re-entrant angle.
When using the silica gel mould to carry out low-melting alloy centrifugal casting, because the thermograde of silica gel mould is little, make metal bath be difficult for forming core, cause the thick of crystal grain, reduced the plasticity and toughness of alloy, have a strong impact on the quality of foundry goods, also influenced the life-span of silica gel mould.
Patent publication No. is that the patent of CN101066552A has proposed a kind of " metal decoration moulding silicon rubber mould material and application thereof ", a kind of metal decoration moulding composition of silica gel mould material is disclosed, make it have good thermal conductivity and hear resistance, the degraded that can reduce the intensification of mold materials and cause thus, the service life of prolongation silica gel mould.But it is little still not solve silica gel mould thermograde, causes thick this shortcoming of casting crystalline grain.
At present in the domestic and international research, also not about controlling the relevant report of silica gel mould thermograde.Therefore, the utility model uses physical method to increase silica gel mould cooling velocity, increases nucleation rate, can effectively avoid chemical thinning method to bring the adverse effect of alloy impurity into when improving cast properties, obtains better mechanical castings.
Summary of the invention
The purpose of this utility model is to overcome existing silica gel mould poor radiation, and the silica gel mould temperature is too high during the alloy cast, and casting crystalline grain is thick, poor mechanical property, the problem that yield rate is low.
The purpose of this utility model realizes in the following way: comprise patrix 3, counterdie 2, patrix runner 6 and die cavity 4, and patrix 3 is installed on the counterdie 2 installation cooling device 1 on patrix 3 and/or the counterdie 2.
Described cooling device 1 can be cooling medium or fin.
The center of the patrix 3 of described silica gel mould has the patrix runner 6 of up/down perforation, and patrix 3 and counterdie 2 have die cavity 4, and the counterdie runner 5 that is communicated with die cavity 4 is arranged on the counterdie 2.
When described counterdie at silica gel mould was installed cooling device 1, cooling device 1 was installed in the center of counterdie 2.
When described cooling device 1 is cooling medium, cooling medium can be iron, copper, zinc, aluminium or magnesium material, when cooling medium is installed in counterdie 2, it is the center that is embedded in counterdie runner 5 surfaces of counterdie 2 and is positioned at counterdie 2, the different lines of cooling medium surface distributed, increase roughness, it is cold excessively to improve curvature.
Described fin is that material stamping-outs such as aluminium alloy, copper alloy or kirsite form, and fin is embedded in upper die and lower die or is embedded in upper die and lower die simultaneously.
Because it is little than metal material to make the silica gel thermal conductivity of silica gel mould, has only 0.16W/ (m.K), and the thermal conductivity of copper is 393.56W/ (m.K), and the thermal conductivity of aluminium is 217.71 W/ (m.K), and the thermal conductivity of silica gel is more than percent even a few one thousandth of metal material.As shown in Figure 1, by in the silica gel mould counterdie, embedding the heat abstractor that a metal material is made, can improve the thermal conductivity of silica gel mould, the heat radiation of acceleration silica gel mould, the heat that discharges when making the cast alloy graining is transmitted to the external world fast, reduces the silica gel mould temperature, increases the foundry goods degree of supercooling, crystal grain thinning, the effect that improves mechanical castings.
Though the specific heat capacity of silica gel is 1700J/ (kg. ℃), big than metal, the density of silica gel is 1.2g/cm
3Little a lot of than metals such as copper, aluminium, iron and steel, the silica gel of equal volume is compared with metal material, the metal material heat absorption capacity is stronger, so in the silica gel mould counterdie, embed the heat abstractor of a metal material, can strengthen the heat absorption capacity of entire die, reduce the degree that the cast alloy raises mold temperature, effectively control the temperature of silica gel mould.
Heat abstractor is a kind of metal material, and the aluminium alloy material is made the weight that heat abstractor can effectively reduce mould, selects for use Cu alloy material to make the thermal diffusivity that heat abstractor can significantly improve mould.
According to the size of silica gel mould and foundry goods, can select the heat abstractor of difformity and size.As shown in Figure 2, heat abstractor is made a boss at the sprue place, reduces the distance of heat abstractor and sprue, can further improve heat-transfer effect.
When heat flow through two contacted solid interfaces, interface itself presented tangible thermal resistance to hot-fluid, is referred to as thermal contact resistance.If can not well contact between silica gel and the fin, can increase thermal resistance on the contrary, make the difficulty of conducting heat, so can connect silica gel mould and heat abstractor by silica gel mould heat curing process, silica gel mould is closely contacted with heat abstractor, increase degree of being connected firmly on the one hand, increase contact-making surface on the other hand, reduce thermal resistance.
Using method of the present utility model: silica gel mould adopts interference fit that patrix is snapped in the counterdie, makes its one-tenth as a whole.The upper and lower mould matched moulds is put into centrifuge and is carried out.
Advantage of the present utility model and good effect:
Adopt said method in silica gel mould, to embed a metal material heat abstractor, can accelerate the silica gel mould radiating rate, silica gel mould is cooled off fast, reduce the generation that silica gel mould burns the mould phenomenon, prolong die life, reduce production costs, increase economic efficiency.
The tradition silica gel mould is subjected to raw-material restriction, when processing ornaments, toy and process gift, can not change the thermal diffusivity of silica gel mould, by in silica gel mould, embedding the mode of fin, make the Mold Making personnel break away from the constraint of silica gel, the silica gel mould of the different thermal diffusivities of development and Design has strengthened the flexibility of technology voluntarily.After silica gel mould does not re-use or scraps, fin can be pulled down and be embedded in other silica gel moulds, be repeatedly used, reach recycling purpose.
