Anti-deformation wax mold structure of frame casting for precision investment casting

Abstract

The utility model discloses an anti-deformation wax mold structure of a frame casting for precision investment casting. The anti-deformation wax mold structure comprises an anti-deformation wax mold structure body capable of dispersing gravity loads on a structural wax mold at a cantilever. Structural wax molds at the cantilevers of the casting wax mold body are connected in a pulling mode through the pulling wax molds, the pulling wax molds disperse stress to the reinforcing frame wax molds through the longitudinal wax molds and the transverse wax molds to be dispersed to the casting wax mold body, and therefore the gravity loads of the structural wax molds at the cantilevers are dispersed. The problem that the structural wax mold at the cantilever is easy to separate or deform due to the fact that the gravity load is not heavy is solved.

Description

Technical Field

[0001] The utility model relates to an anti-deformation wax mold structure for investment casting frame type castings, belonging to the technical field of investment casting. Background Art

[0002] In investment castings, sometimes the casting 1 has a cantilever structure 11. When the wax model tree is built, the wax model itself does not have a heavy gravity load, which can easily cause detachment or deformation. Figure 2 At the same time, after the wax mold sandblasting shell is cast into a casting, the cantilever structure 11 of the casting will also be deformed during tempering. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides an anti-deformation wax mold structure for investment precision casting frame-type castings.

[0004] The utility model is realized through the following technical solutions.

[0005] The utility model provides an anti-deformation wax mold structure for investment casting frame type castings, comprising:

[0006] The anti-deformation wax model structure can distribute the gravity load to the structural wax model at the cantilever.

[0007] The invention comprises: a casting wax mold main body, on which are relatively distributed cantilever structure wax molds, and the cantilever structure wax molds are connected by drawing and connecting wax molds.

[0008] It also includes a reinforcing frame wax mold which is contact-connected and located at the periphery of the casting wax mold body.

[0009] The reinforcing frame wax mold is connected to the tie wax mold through the longitudinal wax mold; the longitudinal wax molds are distributed in multiple intervals, and the longitudinal wax molds are connected to the reinforcing frame wax mold through the transverse wax mold.

[0010] The beneficial effect of the utility model is that the structural wax molds at the cantilever of the casting wax mold body are connected to each other through the tie wax mold, and the tie wax mold distributes the force to the reinforcing frame wax mold through the longitudinal wax mold and the transverse wax mold and disperses it to the casting wax mold body, so that the gravity load of the structural wax mold at the cantilever is dispersed, which solves the problem that the gravity load of the structural wax mold at the cantilever itself is not heavy and it is easy to detach or deform.

[0014] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0015] like Figure 1 shown.

[0016] The present application discloses an anti-deformation wax pattern structure for investment casting frame-type castings, comprising:

[0017] The casting wax mold body 2 is an integral casting wax mold body, on which are relatively distributed cantilever structure wax molds 21 , and the cantilever structure wax molds 21 are connected by a tie wax mold 22 .

[0018] It also includes a reinforcing frame wax mold 3 that is in contact and connected to the outer periphery of the casting wax mold body 2. The reinforcing frame wax mold 3 is connected to the tie wax mold 22 through a longitudinal wax mold 31. The longitudinal wax molds 31 are distributed in multiple intervals, and the longitudinal wax molds 31 are connected to the reinforcing frame wax mold 3 through transverse wax molds 32.

[0019] The cantilever structure wax molds 21 of the casting wax mold body 2 are connected to each other through the tie wax mold 22. The tie wax mold 22 distributes the force to the reinforcing frame wax mold 3 through the longitudinal wax mold 31 and the transverse wax mold 32 and then to the casting wax mold body 2, so that the gravity load of the cantilever structure wax mold 21 itself is dispersed, which solves the problem that the gravity load of the cantilever structure 11 wax mold itself is not heavy and is prone to detachment or deformation; at the same time, after the casting is cast by the wax mold sandblasting shell, the cantilever structure 11 of the casting will not be easily deformed during tempering. The tie wax mold 22, the reinforcing frame wax mold 3, the longitudinal wax mold 31 and the transverse wax mold 32 are Figure 1 The thicker line shows the part.
