A wax pattern flipping device

Abstract

The application discloses a wax mold overturning device, which comprises the following steps: providing force support to the adhesion of the wax mold with an irregular top surface overturned to a downward state and a runner wax mold to achieve a stable wax mold overturning device. The wax mold is matched with a matching groove A and a matching groove B through a root boss and an extension boss respectively. Only the flat bottom surface of the tool body is in stable contact with the operation table plane, so that the wax mold with the irregular top surface is supported. Then, the runner wax mold is adhered to the upward bottom surface of the stable wax mold, which avoids the situation that it is difficult to obtain force support to achieve stability on the operation table plane by taking the irregular top surface as a force basis, and solves the problem that the two clamped force top surfaces and bottom surfaces of the casting wax mold are damaged due to the uneven clamping contact caused by the V-shaped clamping groove on the vice.

Description

TECHNICAL FIELD

[0001] The present application relates to a wax mold overturning device, belonging to the technical field of casting wax mold auxiliary tooling. BACKGROUND

[0002] The quality of wax mold combination in investment casting affects the final quality of the casting, and the bonding conditions of the runner and the runner, and the runner and the casting wax mold in the process of wax mold combination will affect the quality of the final wax mold combination. When bonding the runner wax mold on the casting wax mold, the casting wax mold needs to be stabilized on a stable stress basis, and then the runner wax mold is bonded to the bottom surface of the casting wax mold for fixation. For the casting wax mold 1 with irregular top surface 11, when bonding the runner wax mold 2 on the bottom surface of the casting wax mold 1 (see Figure 1 、 Figure 2 ), it is difficult to obtain stress support on the workbench plane with the irregular top surface 11 as the stress basis.

[0003] The existing wax mold bonding auxiliary tooling, such as the clamping device for wax mold combination in investment casting disclosed in Chinese Patent Publication No. CN204122690U, discloses that a clamping operating rod is installed on a V-shaped clamping groove to support the runner, and after the first layer of wax mold is bonded and combined, the runner is turned over on the vice and fixed, and then the second layer of wax mold is bonded and combined. Although the V-shaped clamping groove on the vice can clamp the casting wax mold, when clamping the casting wax mold with irregular top surface, the two clamped stress top surfaces and the bottom surface of the casting wax mold will be damaged due to uneven clamping contact. SUMMARY

[0004] To solve the above technical problems, the present application provides a wax mold overturning device.

[0005] The present application is realized by the following technical solutions.

[0006] The present application provides a wax mold overturning device, which comprises:

[0007] The wax mold overturning device provides stress support to stabilize the bonding of the wax mold with irregular top surface in the overturned downward state and the runner wax mold.

[0008] The wax mold overturning device comprises a tooling body with axial top surface and bottom surface being flat, and the tooling body is provided with a notch on the circumferential side edge;

[0009] The tooling body located at the inner face of the notch is provided with a matching groove A, which is sunken from the top surface to the bottom surface,

[0010] The tooling body at the matching groove A is provided with a matching groove B, which is sunken from the top surface to the bottom surface, and the matching groove B is in communication with the matching groove A.

[0011] The matching groove A does not penetrate the bottom surface.

[0012] The groove B does not penetrate the bottom surface.

[0013] Also included is an irregular top surface downward wax mold, the wax mold has a root boss, an extension boss, and the extension boss is integrally fixed with the root boss and continuously fixed on the wax mold.

[0014] The irregular top surface of the wax mold is higher than the bottom surface of the tool body.

[0015] The beneficial effects of the present application are that the wax mold is matched with the matching groove A and the matching groove B through the root boss and the extension boss respectively, only the flat bottom surface of the tool body stably contacts the operation table plane, so that the wax mold with irregular top surface is supported, and then the wax mold with irregular top surface is bonded to the runner wax mold, avoiding the situation that the irregular top surface is difficult to be used as a force receiving basis to obtain force support and stability on the operation table plane, and solving the problem that the two clamped force receiving top surfaces and the bottom surface of the casting wax mold are damaged due to uneven clamping contact caused by the V-shaped clamping groove on the vice.

[0022] The technical solutions of the present application are further described below, but the scope of protection is not limited to the description.

[0023] As shown in the figure. Figures 1 to 5

[0024] A wax mold turning device of the present application comprises:

[0025] ​The axial top surface 31 and bottom surface 32 are both flat, as shown in 4, and the tool body 3 is provided with a notch 33 on the circumferential side for clamping the wax mold 1.

[0026] The tool body 3 at the inner surface of the notch 33 is provided with a matching groove A4, which is sunken from the top surface 31 to the bottom surface 32, as shown in Figure 3 The matching groove A4 cooperates with the upper root boss 14 of the wax mold 1.

[0027] The tool body 3 at the matching groove A4 is provided with a matching groove B5, which is sunken from the top surface 31 to the bottom surface 32, and the matching groove B5 is in communication with the matching groove A4, as shown in Figure 3 The matching groove B5 cooperates with the extended boss 13 of the wax mold 1.

[0028] The wax mold 1 is turned over so that the irregular top surface 11 faces downward, as shown in Figures 1 to 2 The bottom surface of the wax mold 1 is upward, and the wax mold 1 is matched with the tool body 3 through the root boss 14 and the extended boss 13, respectively, which correspond to the matching groove A4 and the matching groove B5, so that the wax mold 1 is not moved. At this time, the irregular top surface 11 of the wax mold 1 faces downward and is higher than the bottom surface 32 of the tool body 3, so that the irregular top surface 11 of the wax mold 1 does not contact the workbench plane, but the flat bottom surface 32 of the tool body 3 stably contacts the workbench plane, so that the wax mold 1 with the irregular top surface 11 is supported, and then the wax mold 1 is upwardly bonded to the runner wax mold 2, as shown in Figure 5 The irregular top surface 11 is difficult to be used as a force basis to obtain force support and stability on the workbench plane, and the V-shaped clamping groove on the vice can clasp the wax mold 1, but the two clamped force top surfaces and bottom surfaces of the wax mold may be damaged due to uneven clamping contact.
