Description

Technical Field

[0001] This utility model relates to the field of smelting molds, and in particular to a smelting mold for producing high-temperature alloy castings. Background Technology

[0002] The smelting of high-temperature alloys generally involves steps such as batching, smelting, refining, and casting.

[0003] During casting, the refined high-temperature alloy solution is poured smoothly and quickly through the gate into the cavity of the already closed smelting mold and waits for it to cool.

[0004] However, existing casting molds do not adjust the angle again after mold closing. During the casting process, air or gas will be drawn in by the high-temperature alloy solution. If the gas cannot be discharged smoothly, it will form pores inside the casting, reducing the density and mechanical properties of the casting. Moreover, high-temperature alloys usually contain a variety of alloying elements. During the casting and cooling process, due to the difference in gravity and solidification rate, compositional segregation is prone to occur, resulting in inconsistent performance of different parts of the casting.

[0005] Therefore, it is necessary to provide a smelting mold for the production of high-temperature alloy castings to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides a smelting mold for producing high-temperature alloy castings, which solves the problem that existing casting molds do not readjust their angle after mold closing, and that air or gas is drawn into the high-temperature alloy solution during casting. If the gas cannot be discharged smoothly, it will form pores inside the casting, reducing the density and mechanical properties of the casting. Moreover, high-temperature alloys usually contain multiple alloying elements, and during casting and cooling, due to differences in gravity and solidification rate, compositional segregation is prone to occur, leading to inconsistent performance in different parts of the casting.

[0007] To solve the above-mentioned technical problems, this utility model provides a smelting mold for producing high-temperature alloy castings, comprising: a mounting base;

[0008] The driving device comprises two sets of driving devices fixedly installed on both sides of the outer surface of the mounting base. Each driving device includes a mounting plate, a first driving component, and a connecting rod. A lower mold is provided on one side of the driving device, and the driving device is used to drive the lower mold to rotate.

[0009] An upper mold is disposed on top of a lower mold. A second assembly plate is fixedly installed on the outer surface of the upper mold, and a first assembly plate is fixedly installed on the outer surface of the lower mold.

[0010] Preferably, support columns are fixedly installed around the bottom of the mounting base, and a base is fixedly installed at the bottom end of the support columns. A demolding component is provided in the middle of the bottom of the lower mold.

[0011] Preferably, a limiting device is fixedly installed on both sides of the top of the base. The limiting device includes a lifting member and a support plate. The lifting member is fixedly installed on one side of the top of the base, and the support plate is fixedly connected to the top end of the output shaft of the lifting member.

[0012] Preferably, the mounting plate is fixedly mounted on one side of the outer surface of the mounting base, the first driving member is fixedly mounted in the middle of one side of the outer surface of the mounting plate, and the connecting rod is fixedly connected to the end of the output shaft of the first driving member.

[0014] Preferably, support plates are fixedly installed on both sides of the outer surface of the base, and a second driving member is fixedly installed on one side of the outer surface of one of the support plates, and a rotating rod is fixedly connected to the end of the output shaft of the second driving member.

[0015] Preferably, the rotating rod is fixedly connected to the inside of the base.

[0016] Compared with related technologies, the smelting mold for producing high-temperature alloy castings provided by this utility model has the following beneficial effects:

[0017] This invention provides a smelting mold for producing high-temperature alloy castings. The output shaft of the first driving component rotates alternately in both directions, driving the connecting rod to rotate. The connecting rod then drives the lower and upper molds to rotate and tilt in both directions. This device has a simple structure and strong practicality. By rotating the mold to tilt it, the flow direction of the alloy solution is changed, making it easier for gas to rise to the surface of the solution and then be discharged from the mold cavity.

[0028] Support columns 7 are fixedly installed around the bottom of the mounting base 1, and a base 8 is fixedly installed at the bottom end of the support columns 7. A demolding component 10 is provided in the middle of the bottom of the lower mold 3.

[0029] Both sides of the top of the base 8 are fixedly installed with limiting devices 9. The limiting devices 9 include a lifting member 91 and a support plate 92. The lifting member 91 is fixedly installed on one side of the top of the base 8, and the support plate 92 is fixedly connected to the top end of the output shaft of the lifting member 91.

[0030] The mounting plate 21 is fixedly installed on one side of the outer surface of the mounting base 1, the first driving member 22 is fixedly installed in the middle of one side of the outer surface of the mounting plate 21, and the connecting rod 23 is fixedly connected to the end of the output shaft of the first driving member 22.

[0031] The first driving component 22 adopts a servo motor structure, and the lifting component 91 adopts a hydraulic cylinder structure.

[0032] The upper mold 5 and the lower mold 3 are equipped with water cavities inside, which are connected by water pipes for cooling.

[0033] The output shaft of the lifting component 91 pushes the support plate 92 to support the bottom surface of the mounting base 1, so that the bottom of the lower mold 3 is flat and fits against the top of the support plate 92, keeping the lower mold 3 horizontally supported.

[0034] When the mold needs to be tilted, the support plate 92 can be controlled to move downward to release the support of the lower mold 3.

[0035] The demolding assembly 10 includes a hydraulic cylinder and a push plate. The output shaft of the hydraulic cylinder extends to the interior of the lower mold 3 and connects to the push plate. The push plate is slidably installed at the bottom of the casting groove of the lower mold 3. The output shaft of the hydraulic cylinder pushes the push plate to move up and down, pushing out the molded part inside the lower mold 3 to form demolding, which is an existing demolding technology.

The refined high-temperature alloy solution is injected into the mold through the gate.

[0038] The output shaft of the first driving component 22 is controlled by an external power source to rotate alternately in both directions, which in turn drives the connecting rod 23 to rotate.

[0047] The working principle of the smelting mold for producing high-temperature alloy castings provided by this utility model is as follows:

[0048] During operation, the output shaft of the second drive component 12 is first rotated alternately in both directions by the external power supply, which drives the rotating rod 13 and the base 8 to rotate alternately in both directions, causing the base 8 to tilt the mold to both sides.
