Description

Technical Field

[0001] The present application relates to the technical field of casting production technology, and in particular to a titanium alloy casting mold shell support device. Background Art

[0002] Titanium alloys have become indispensable advanced structural materials in modern industry due to their excellent comprehensive properties, such as low density, high specific strength, high temperature resistance and corrosion resistance. Especially in recent decades, with the rapid development of the aviation field and the defense industry, the use and application level of titanium alloys have been significantly improved. However, due to its high chemical activity, low thermal conductivity and low plasticity, titanium alloys are difficult to form under traditional processing methods, which undoubtedly limits the further application of titanium alloys. In order to break this deadlock, the investment casting technology with near-net-shape process was studied and developed to cast titanium alloy components.

[0003] Investment casting is also called lost wax casting: (1) Making wax mold: Make a mold with the same shape and size as the required titanium alloy casting, and then use soluble primary mold material, such as wax, to die-cast to form a wax mold. (2) Making mold shell: After removing the wax mold and cleaning it, heat-melt the end of the wax mold on the support, then clamp the support, apply paint, and then spray a coating, such as quartz sand, and then dry it. After repeating this process many times, dry and harden it so that the surface of the wax mold forms a solid mold shell structure with a certain thickness. The support part provides a channel for the mold shell to flow out after the wax mold melts. (3) Dewaxing: Set the wax mold in the hot melting chamber to promote the hot melting of the wax mold, leaving only the mold shell, thereby obtaining the mold shell. (4) Casting: Pour the molten liquid titanium alloy into the mold shell, and solidify it after degassing and other processes. (5) After the casting is out of the furnace, it is slide-polished and heat-treated, and stored after passing the inspection.

[0004] In the above process, when the mold shell is dewaxed, it is mostly baked and heat treated in a hot melt chamber or hot melt box, or poured with hot water, or fumigated with hot steam to melt the wax and flow out from the mold shell port. These methods are all steaming and baking from the outside to the inside, heating and melting from the outside to the inside, which is not only inefficient, but also has a delayed pressure, which can easily cause the mold shell to crack and affect the mold shell yield. In addition, when the mold shell is made, the wax mold support is hot-melted on the support after it is completed, which not only increases the process steps; then in the dewaxing process, after the wax mold melts, the support falls into the wax liquid, and it needs to be salvaged later, which increases the labor burden.

[0005] To this end, the present application provides a titanium alloy casting mold shell support device, so that the wax mold can be heated more evenly during the dewaxing process, which can not only improve the demolding efficiency but also reduce the mold shell scrap rate; at the same time, during dewaxing, it can also prevent the support from falling into the wax liquid to increase subsequent problems; and the mold shell can remain stable during dewaxing.

DETAILED DESCRIPTION

[0044] The following will be combined with the attached examples of the present application Figure 1-15 , the technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0045] Embodiment 1, in order to solve the problem of uneven heating of the mold shell 4 during dewaxing in the prior art, which leads to cracking of the mold shell 4, this embodiment provides a titanium alloy casting mold shell support device, comprising:

[0046] The wax model support 12 is used to fix the wax model 3. The wax model support 12 is provided with a water inlet pipe 13 and a drain pipe 15 at intervals. The water inlet pipe 13 is connected to a plurality of shunt pipes 14 inserted into the wax model 3. The ends of the shunt pipes 14 are connected to the drain pipe 15.

[0047] A support frame 1, the upper axis of the support frame 1 is provided with a sink groove 17 for embedding the bottom end of the wax model support 12, and the sink groove 17 and the wax model support 12 embedded in the sink groove 17 are both non-circular structures; the end surface of the support frame 1 is located at the periphery of the sink groove 17 and has a plurality of main splints 2 in a circular array, and the plurality of main splints 2 are synchronously gathered or separated by the claw plate driving structure, and each main splint 2 is vertically spaced and rotatably installed with a secondary splint 1 5 on the side facing the axis of the support frame 1, and each secondary splint 1 5 is vertically spaced and rotatably installed with a plurality of secondary splints 2 6, and each secondary splint 2 6 is vertically spaced and rotatably installed with a plurality of secondary splints 3 7;

[0048] The wax receiving barrels 8 are divided into multiple groups and assembled into a ring shape. The outer wall of the bottom end of the wax receiving barrels 8 is in contact with the inner wall of the sink 17, and the inner wall is in contact with the outer wall of the wax model support 12. The bottom end of each group of wax receiving barrels 8 is connected to a discharge pipe 16, which passes through the sink 17.

[0049] Principle details of this embodiment:

[0050] A titanium alloy casting mold shell support device includes: a wax mold support 12 for carrying and fixing a wax mold 3, a support frame 1 for embedding the wax mold support 12 and lifting the mold shell 4, and a wax receiving barrel 8 for receiving and transferring molten wax liquid.

[0051] The wax model support 12 is made of a material that is resistant to high temperatures and not easily deformed, and has a rough surface. The wax model support 12 is provided with a socket 1 and a socket 2 at intervals. A water inlet pipe 13 is inserted into the socket 1, and the water outlet of the water inlet pipe 13 is inserted into the wax model 3 and is connected to a plurality of shunt pipes 14 located in the wax model 3. The ends of the plurality of shunt pipes 14 are commonly connected to a water storage chamber located in the wax model 3, and the water storage chamber is connected to a drain pipe 15. The drain pipe 15 passes through the wax model 3 and then passes through the wax model support 12 from the socket 2. A one-way valve is provided at the position where the shunt pipe 14 is connected to the water storage chamber to prevent hot water from backflowing. The water inlet pipe 13, the shunt pipe 14, the drain pipe 15, and the water storage chamber are all made of materials that are resistant to high temperatures and not easily deformed, such as copper.

[0052] In order to realize the integral distribution structure of the wax model support 12, the wax model 3, the water inlet pipe 13, the diversion pipe 14, the water storage chamber, and the drain pipe 15, in this embodiment, refer to the attached Fig.15 As shown, a wax mold 3 die-casting mold (hereinafter referred to as a die) is also designed to cooperate with the wax mold support 12. In addition to the die having a cavity with the same shape and size as the titanium alloy workpiece, an installation cavity is also provided in the upper and lower molds of the die at the end of the cavity away from the pouring port, and the installation cavity is connected with the cavity. After the installation cavities on the upper and lower molds are combined, they can be tightly fastened to the outer wall of the support without leaving any gaps. The installation cavity also leaves space gaps for the water inlet of the water inlet pipe 13 and the drain outlet of the drain pipe 15. When the wax mold 3 is made, the end of the wax mold support 12 is embedded in the installation cavity of the lower mold, and then the upper mold is closed and fastened. Thereafter, wax liquid is poured into the cavity through the pouring port, and the wax liquid accumulates in the cavity and wraps the water inlet pipe 13, the diversion pipe 14, the water storage chamber, and the drainage pipe 15. After condensation, the wax mold 3 and the wax mold support 12 form an integrated structure and cover all the pipelines. This one-piece molding does not require the subsequent step of hot-melting the wax mold 3 and fixing it on the support, which not only saves manpower, but also shortens the entire casting time, thereby indirectly improving the casting efficiency.

[0053] The upper end of the support frame 1 is disc-shaped, and there are multiple legs in a circular array around the disc. A sink 17 is provided at the upper axis of the disc-shaped part of the support frame 1. The shape and size of the sink 17 are completely consistent with the bottom part of the wax model support 12, and is used to embed the wax model support 12. A through hole is provided at the axis of the sink 17. The diameter of the through hole is smaller than the bottom end of the wax model support 12, providing space for the water inlet of the water supply pipe 13 and the drain outlet of the drain pipe 15. In addition, the sink 17 and the wax model support 12 embedded in the sink 17 are non-circular structures, such as rectangular, plum blossom, etc., so that after the wax model support 12 is placed in the sink 17, the degree of freedom is limited. Except for pulling it out upward from the port of the sink 17, it cannot be detached in other directions, which increases the restriction on the wax model support 12. The end face of the support frame 1 is located in the surrounding circular array of the sink 17 with multiple main clamps 2, which are used to lift and clamp the mold shell 4. The multiple main plates 2 are synchronously gathered or separated by the claw plate driving structure, and the claw plate driving structure refers to the structure of the three-claw chuck 18. Each main plate 2 is vertically and spacedly mounted with a semicircular auxiliary plate 1 5 on the side facing the axis of the support frame 1, and each auxiliary plate 1 5 is vertically and spacedly mounted with a plurality of semicircular auxiliary plates 2 6, and each auxiliary plate 2 6 is vertically and spacedly mounted with a plurality of semicircular auxiliary plates 3 7.

[0054] The rotational connection structures between the auxiliary splint 1 5 and the main splint 2, the auxiliary splint 2 6 and the auxiliary splint 1 5, and the auxiliary splint 3 7 and the auxiliary splint 2 6 are the same. Take the main splint 2 and the auxiliary splint 1 5 as examples: a semicircular groove is provided on the end face of the main splint 2 facing the axis of the sink 17, and the shape and size of the semicircular groove match the shape and size of the auxiliary splint 1 5. A slot is provided on the end face of the semicircular groove along the outer edge of the semicircular groove. The slot does not penetrate the end face of the main splint 2 and is a closed groove body. A plug rod is provided on the end face of the auxiliary splint 1 5 close to the outer edge. The auxiliary splint 1 5 is embedded in the semicircular groove, and the plug rod is inserted into the slot, so that the auxiliary splint 1 5 swings within the range of the semicircular groove and will not fall off. In this way, the rotational connection between the auxiliary splint 1 5 and the main splint 2 is completed, and the rest of the structure is the same. The main plate 2, the auxiliary plate 1 5 and the auxiliary plate 2 6 are all two-piece structures, that is, they are divided into two halves along the center line, and the two halves are fastened and installed by fasteners such as screws, providing a disassembly and assembly basis for the installation of the next level components.

[0055] The wax receiving barrel 8 is divided into multiple groups of fan-shaped barrels, which are assembled together to form a ring. The outer wall of the bottom end of the wax receiving barrel 8 assembled together by multiple groups of fan-shaped barrels fits with the inner wall of the sink 17, and the inner wall fits with the outer wall of the wax mold support 12, so as to achieve the purpose of being embedded in the sink 17. The lower port of the mold shell 4 is completely located within the barrel mouth range of the wax receiving barrel 8 to ensure that the wax liquid after hot melting will not overflow. The bottom wall of the sink 17 is provided with a socket three corresponding to the fan-shaped barrels one by one, and each group of wax receiving barrels 8 is connected to a feed pipe 16 at the bottom end. The feed pipe 16 passes through the sink 17 from the socket three and extends from the lower end of the support frame 1. The wax receiving container is placed under the support frame 1 to recover the wax liquid. After the bottom end of the wax mold support 12 is embedded in the sink 17, there is still space for the wax receiving barrel 8 to be embedded. The wax receiving barrel 8 is embedded in the sink 17 and will not deviate to form a gap, causing the wax liquid to leak out of the wax receiving barrel 8.

[0056] According to the above technical solution:

[0057] When in use, the wax mold support 12 with the wax mold 3 is placed in the sink 17, and then the fan-shaped barrels are embedded one by one in the sink 17 to splice into a wax receiving barrel 8. After that, the multiple main splints 2 are driven to move closer to the axial direction of the sink 17 through the chuck drive mechanism. After the multiple auxiliary splints 3 7 contact the mold shell 4, as the concave and convex changes of the outer surface of the mold shell 4, the auxiliary splints 3 7, the auxiliary splints 2 6, and the auxiliary splints 1 5 deflect to fit the mold shell 4; or part of the auxiliary splints 3 7 contacts the surface of the mold shell 4. Thereby, the lifting and clamping of the mold shell 4 is completed. After that, the support frame 1 is placed in the hot melt chamber, and the water inlet pipe 13 is connected to the hot water tank through a pump, and the drain pipe 15 is connected to the other side of the hot water tank. There is an electric heating component in the hot water tank.

[0058] Then start the pump, which draws the hot water in the hot water tank into the water inlet pipe 13, and then flows along the diversion pipe 14, and then flows back to the hot water tank along the drain pipe 15, and the hot water circulates. The heat dissipated during the flow of hot water causes the wax mold 3 to heat up until it melts. The melted wax liquid drips from the lower end of the mold shell 4 and falls into the wax receiving barrel 8, and falls into the wax receiving container below along the discharge pipe 16 for wax liquid recovery. After dewaxing is completed, the mold shell 4 is loosened through the claw disk drive structure, the mold shell 4 is removed, and then the wax receiving barrel 8 is taken out, and then the wax mold support 12 is taken out to complete the entire dewaxing process.

[0059] In summary, during dewaxing, under the action of the shunt pipe 14, the heat is evenly dispersed into the wax mold 3, so that the wax mold 3 is heated evenly and melted to a similar degree, thereby avoiding the problem of possible cracking due to temperature difference in the mold shell 4. The hot water circulates, which can not only provide thermal energy with stable flow and heat, but also recover heat and reduce heat waste. After the wax mold 3 is melted, the wax liquid drips into the wax receiving barrel 8, and the wax mold support 12 is located in the sink 17, so that the wax mold support 12 is isolated from the wax liquid, saving subsequent salvage and cleaning operations. During the dewaxing process, the mold shell 4 is clamped and lifted by the main splint 2 and the multi-stage auxiliary splint, which avoids the subsequent problems such as the mold shell 4 falling and being damaged without stable support after the wax mold 3 melts, and the wax liquid is thrown out of the wax receiving barrel 8. In addition, the cooperation of the main splint 2 and the multi-stage auxiliary splint can be applied to columnar regular or irregular mold shells 4 with different calibers and different structures, and the flexibility of use is greatly improved.

[0060] In this embodiment, the wax model support 12 and the wax receiving barrel 8 are thermally conductive, and the wax receiving barrel 8 is heated to prevent the wax liquid from solidifying and staying in the wax receiving barrel 8, thereby ensuring the smoothness of the wax liquid guidance.

[0061] Embodiment 2, in a further embodiment of the present solution, in this embodiment, a specific claw disk driving structure is provided that allows all chucks 18 to be synchronously approached or separated:

[0062] The claw disk driving structure includes an annular chuck 18 rotatably mounted on the support frame 1, the inner diameter of the chuck 18 is larger than the diameter of the sink groove 17, the end face of the chuck 18 is provided with a flat rectangular thread 19, the bottom end of the main splint 2 is meshed with the flat rectangular thread 19, the main splint 2 is radially slidably installed on the end face of the support frame 1, the outer edge surface of the chuck 18 is provided with a worm wheel 9, the worm wheel 9 is meshed with a worm 10 rotatably mounted on the support frame 1, and the shaft end of the worm 10 is provided with a ratchet wrench 11.

[0063] Principle details of this embodiment:

[0064] The claw disk driving structure includes an annular chuck 18, which is rotatably mounted on the upper end face of the support frame 1. The inner diameter of the chuck 18 is larger than the diameter of the sink 17, and does not affect the embedding of the wax model support 12 and the wax receiving barrel 8. A flat rectangular thread 19 is provided on the upper end face of the chuck 18, and the flat rectangular thread 19 is vortex-shaped. A vortex groove is provided at the bottom end of the main splint 2, and the vortex groove is meshed with the flat rectangular thread 19 to achieve the matching relationship between the main splint 2 and the chuck 18. The main splint 2 is radially slidably installed on the end face of the support frame 1, and a worm wheel 9 is fixed on the outer edge surface of the chuck 18 through a sleeve, and the worm wheel 9 is meshed with a worm 10 rotatably mounted on the support frame 1. Rectangular shafts are provided at both ends of the worm 10, which are used in conjunction with a ratchet wrench 11, and there is no need to rotate the wrench a full circle. In this way, the space for the worm wheel 9 and its driving part to extend outward from the support frame 1 is reduced, and the problem of drive interference is also avoided.

[0065] Embodiment 3, in a further embodiment of this scheme, in order to prevent the chuck 18 from being exposed outside the support frame 1, the flat rectangular thread 19 needs additional cleaning due to dust or wax dripping on it. In this embodiment, the end face of the support frame 1 is provided with an annular inner cavity 103, the chuck 18 is rotatably installed in the inner cavity 103, the top wall of the inner cavity 103 is provided with a slide groove 20, and the main splint 2 penetrates into the inner cavity 103 from the slide groove 20 and engages with the flat rectangular thread 19. That is, the isolation of the chuck 18 is achieved, and the sliding fit connection between the main splint 2 and the support frame 1 can be achieved.

[0066] Embodiment 4, in a further embodiment of this scheme, after the wax model support 12 is inserted into the sink 17, the position is fixed, and some components are irregular cylindrical, and the position of the main plate 2 needs to be adjusted to adapt to the cylindrical titanium alloy mold shell 4 structure of different shapes. Therefore, in this embodiment, the support frame 1 includes a fixed seat 101 and a rotating ring 102 rotatably mounted on the fixed seat 101, the sink 17 is set at the axis of the fixed seat 101 and located in the inner diameter of the rotating ring 102, and the chuck 18 driving structure is set on the rotating ring 102.

[0067] Principle details of this embodiment:

[0068] The support frame 1 includes a fixed seat 101 and a swivel 102 rotatably mounted on the fixed seat 101. The legs are arranged around the fixed shaft. The fixed seat 101 is convex, and the swivel 102 is rotatably mounted on the end surface of the fixed seat 101 where the shaft diameter changes. The sink 17 is arranged at the axis of the fixed seat 101 and is located in the inner diameter of the swivel 102. The inner cavity 103 is placed in the swivel 102, so that the chuck 18 driving structure is arranged on the swivel 102.

[0069] When in use, the rotating ring 102 can be driven to deflect to adapt to the shape of the mold shell 4 (the device in this solution is suitable for cylindrical regular or irregular components), thereby improving the applicability and flexibility of use of the device.

[0070] Embodiment 5, in a further embodiment of this scheme, the bottom end of the main plate 2 extends into the inner cavity 103 and meshes with the plane rectangular thread 19. When the main plate 2 or the auxiliary plate on it needs to be replaced and repaired, it is inconvenient to disassemble and assemble. Therefore, in this embodiment, the main plate 2 includes a sliding member 201 and a disassembly member 202. The sliding member 201 and the disassembly member 202 are detachably connected. The disassembly member 202 has different shapes and models. The auxiliary plate 5 is rotatably mounted on the disassembly member 202. The bottom end of the sliding member 201 penetrates into the inner cavity 103 from the slide groove 20 and meshes with the plane rectangular thread 19.

[0071] Principle details of this embodiment:

[0072] The main plate 2 comprises a sliding member 201 and a disassembling member 202, wherein the sliding member 201 is detachably connected to the disassembling member 202, and the auxiliary plate 5 is rotatably mounted on the disassembling member 202, and the bottom end of the sliding member 201 penetrates into the inner cavity 103 from the slide groove 20 and meshes with the plane rectangular thread 19. Thus, the multi-stage auxiliary plate can be replaced with the disassembling member 202, so that the connection part between the main plate 2 and the multi-stage auxiliary plate and the connection part with the swivel 102 are separated, and can be replaced separately, which is more convenient to use.

[0073] Embodiment 6, in a further embodiment of the present scheme, in this embodiment, a detachable connection method of a quick-disconnect and quick-assemble disassembly component 202 and a sliding component 201 is provided: the sliding component 201 is provided with a trapezoidal groove 203 inclined downwardly toward the end away from the axis of the support frame 1, the upper end of the trapezoidal groove 203 and the side facing the axis of the support frame 1 are both open, and the bottom end of the disassembly component 202 is provided with a trapezoidal block 204 that cooperates with the trapezoidal groove 203.

[0074] When in use, the assembly of the disassembly member 202 and the sliding member 201 can be realized by inserting the trapezoidal block 204 into the trapezoidal groove 203. The trapezoidal groove 203 is inclined downward toward the side away from the axis of the support frame 1, so that the disassembly member 202 has a tendency to move down along the trapezoidal groove 203 by its own weight. In this way, even without fasteners or the like, it can maintain a relatively stable state and will not fall off easily, so that the disassembly member 202 can be quickly disassembled and assembled, and the replacement efficiency is improved.

[0075] Embodiment 7, in a further embodiment of this solution, the existence of the chute 20 allows the inner cavity 103 to still have a through channel with the outside world, and then there is the possibility of dust falling and wax dripping. Therefore, in this embodiment, the sliding member 201 is provided with telescopic rods 21 on both sides along the direction of the chute 20, and the width of the telescopic rod 21 is greater than the width of the chute 20 and the length is greater than the length of the chute 20. The chute 20 is blocked by the telescopic rod 21 to ensure the isolation of the inner cavity 103 from the outside world.

[0076] In this embodiment, in order to make the telescopic rod 21 fit tightly against the end surface of the slide groove 20, the lower end of the fixed end of the telescopic rod 21 fixed on the sliding member 201 is open, and a movable end is installed in the fixed end via a spring, and the bottom end of the movable end is flush with the bottom end of the fixed end, thereby ensuring that it fits tightly against the end surface of the slide groove 20.

[0077] Embodiment 8, in a further embodiment of the present scheme, some components may be clamped by the main clamping plate 2 and the multi-stage auxiliary clamping plates in a lifted state, and the hot water injected into the water inlet pipe 13 by the pump has a certain impact, which may cause the wax model support 12 to loosen. Therefore, in this embodiment, the wax receiving barrel 8 is convex, the depth of the sink 17 is exactly the same as the height of the embedded part of the wax model support 12, and the upper end surface of the convex part of the wax receiving barrel 8 is flush with the end surface of the rotating ring 102. After the sliding member 201 moves, the extended end of the telescopic rod 21 abuts against the side wall of the wax receiving barrel 8, thereby blocking the wax receiving barrel 8, and the wax receiving barrel 8 abuts against the outer extension of the bottom end of the wax model support 12, thereby limiting the wax receiving barrel 8, and then the mold shell 4 remains vertically stable during the initial clamping.

[0078] Embodiment 9, in a further embodiment of this scheme, since the columnar titanium alloy component also has different shape structures (such as convex or side eaves at different positions), the applicability of the main plate 2 and the multi-stage auxiliary plate of the same structure is relatively low. Therefore, in this embodiment, the disassembly and assembly part 202 has different shapes. In this embodiment, the side of the disassembly and assembly part 202 facing the sink 17 is a flat surface, and can also be any one of an outer convex surface, an inner concave surface, a curved surface, and a wavy surface, so as to be suitable for different component mold shells 4.
