Abstract
The utility model discloses a fired mould for casting a high temperature alloy thin section casting, which belongs to the fired mold mould. The utility model aims to provide a fired mold mould capable of preventing the casting from contraction and cracking. The fired mould for casting the high temperature alloy thin section casting comprises a wax mould (1), and a fireproof shell coating the surface of the wax mould. The fireproof shell consists of a fireproof inner shell (2) coating the surface of the wax mould (1), a separation layer (3) coating the surface of the fireproof inner shell (2) and a fireproof outer shell (4) coating the surface of the separation layer. The fireproof inner shell provided by the utility model not only slide with the casting which is solidified and contracted to lighten blocking of the shell on contraction of casting and eliminate the factors that generate cracks, but also has the insulating effect by the gap between the fireproof inner shell and the fireproof outer shell so as to improve the quality of casting. The utility model is a fired mould for casting the high temperature alloy thin section casting.
Description
Technical field:The utility model relates to a kind of mould, relates in particular to a kind of investment pattern die.
Background technology:As everyone knows, when the casting high-temperature alloy thin-section casting, adopt the investment shell mould usually; This mould is made through dry, dewaxing by the refractory material of brushing on the wax-pattern surface.The obstruction that in the solidification shrinkage process, can receive shell owing to foundry goods cracks, so percent defective is high.
Summary of the invention:To the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of fusible pattern that can avoid the casting high-temperature alloy thin-section casting of foundry goods shrinkage cracking.
To achieve these goals, the utility model adopts following technical scheme: comprise wax-pattern, be coated on the surperficial fire-resistant shell of this wax-pattern; This fire-resistant shell is made up of the fire-resistant inner casing that is coated on wax-pattern surface, the separation layer that is coated on this fire-resistant inner casing surface, the refractory outer cover that is coated on this insulation surface.
Compare with prior art; The utility model is owing to adopted technique scheme; Changed the fire-resistant shell that was coated on the wax-pattern surface originally into three-decker: first brushing one deck refractory material is as fire-resistant inner casing on the wax-pattern surface; Be stained with on the surface of this fire-resistant inner casing and cover one deck husk or wood fragments bits as separation layer, and then at external coating one deck refractory material of this separation layer as refractory outer cover; Therefore when fire-resistant shell being carried out the roasting typing, consider to be worth doing as the husk of separation layer or wood fragments and also can burn and between fire-resistant inner casing and refractory outer cover, form the space.Like this, in casting cycle, fire-resistant inner casing can slide with the foundry goods of solidification shrinkage, thereby has alleviated obstruction that shell shrinks foundry goods, eliminated the factor that crackle produces, and has improved casting qualified rate; In addition, insulation effect can also be played in the space between fire-resistant inner casing and the refractory outer cover, helps improving casting quality.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Among the figure: wax-pattern 1 fire-resistant inner casing 2 separation layers 3 refractory outer covers 4
The specific embodiment:Below in conjunction with accompanying drawing and concrete embodiment the utility model is described further:
As shown in Figure 1, be coated with fire-resistant inner casing 2 on the surface of wax-pattern 1, be coated with separation layer 3 on the surface of this fire-resistant inner casing, be coated with refractory outer cover 4 on the surface of this separation layer.During making, some at the external coating of wax-pattern 1 earlier all over reaching design thickness by the formulated slurry of refractory material, form fire-resistant inner casing 2; Perfuse husk or wood fragments bits then on the still undried surface of this fire-resistant inner casing, form separation layer 3; After treating fire-resistant inner casing dry tack free, some at the external coating of separation layer 3 again all over reaching design thickness by the formulated slurry of refractory material, form refractory outer cover 4; Treat after this refractory outer cover drying whole shell to be carried out roasting, typing, the wax material of discharging fusing at last gets final product.
Claims (1)
1. the fusible pattern of the high-temperature alloy thin-section casting of casting comprises wax-pattern (1), is coated on the surperficial fire-resistant shell of this wax-pattern; It is characterized in that: this fire-resistant shell is made up of the fire-resistant inner casing (2) that is coated on wax-pattern (1) surface, the separation layer (3) that is coated on this fire-resistant inner casing surface, the refractory outer cover (4) that is coated on this insulation surface.
