Description

[0002] Currently, in the field of high-temperature alloy casting for aerospace, wax pattern preparation and treatment are key steps to ensure the accuracy of castings and directly affect the quality of subsequent alloy forming. However, existing wax pattern treatment devices have many shortcomings in practical applications and cannot meet the stringent requirements of aerospace casting for high precision and high stability.

[0003] Among them, the existing heating components are mostly fixed structures, which can only heat a local area of ​​the inner wall of the wax mold and cannot fully cover all parts of the inner wall. There are obvious heating dead spots, resulting in insufficient melting of the wax layer and a lot of residue, which requires additional manual cleaning, increasing the operation process and error risk. An improperly designed wax collection system can cause melted wax to drip onto equipment surfaces or workbenches, resulting in low collection efficiency.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1, referring to Figures 1 to 6 This is the first embodiment of the present invention, which provides a high-temperature alloy casting device for aerospace applications, capable of achieving uniform heating of the interior of a wax mold, comprising: A bracket 1 is provided inside the bracket 1, and a number of wax molds 18 are fixedly connected to the mold frame 17. A clamping component and a driving component are respectively provided on both sides of the mold frame 17. The clamping component is used to clamp the mold frame 17, and the driving component is used to drive the mold frame 17 to rotate. A workbench 2 is fixedly connected to the bottom of the inner side of the bracket 1. A base box 23 is installed on the top of the workbench 2 via a lifting component. Several insertion rods 25 are provided on the top of the base box 23. Heating components are installed on the insertion rods 25. The insertion rods 25 correspond to the ports of the vertical wax mold 18. The heating components are used to heat and melt the wax on the inner wall of the wax mold 18. The reciprocating mechanism is located inside the bottom box 23. The reciprocating mechanism can drive the insertion rod 25 to rotate back and forth. It can first drive the insertion rod 25 to rotate forward half a turn, and then rotate backward half a turn.

[0033] In use, the clamping component is activated and applies clamping force to the mold frame 17 inside the bracket 1, fixing the position of the mold frame 17; then the drive component outputs power, driving the fixed mold frame 17 to rotate at a constant speed around a preset axis, ensuring that several wax molds 18 on the mold frame 17 rotate synchronously; the lifting component at the bottom of the workbench 2 receives the control signal and drives the base box 23 to rise and fall vertically, adjusting the height of the base box 23 until the insertion rod 25 is precisely aligned with the port of the vertical wax mold 18, so that the insertion rod 25 is inserted into the wax mold 18; at the same time, the heating component is powered on and starts to heat the wax layer on the inner wall of the wax mold 18 in a targeted manner; the reciprocating mechanism inside the base box 23 operates synchronously, driving the insertion rod 25 to rotate forward half a turn and then reverse half a turn through the transmission structure, ensuring that the heating component fully sweeps the inner wall of the wax mold 18; after the wax layer melts, the collection mechanism, driven by the dedicated drive component, starts the wax recovery process, collecting the melted wax and transporting it to a designated container.

[0034] Specifically, the clamping assembly includes a first electric push rod 15 fixedly installed at one end of the side wall of the bracket 1, and a push plate 16 rotatably installed at the drive end of the first electric push rod 15, with the outer wall of the push plate 16 corresponding to one end of the mold frame 17.

[0035] When it is necessary to fix the mold frame 17, the external controller sends a command to the first electric push rod 15. The drive end of the first electric push rod 15 extends axially and pushes the push plate 16, which is rotatably connected to it, to move towards the mold frame 17 until the outer wall of the push plate 16 is tightly fitted with one end of the mold frame 17. The clamping force of the push plate 16 on the mold frame 17 can be precisely controlled by adjusting the extension length of the electric push rod, so as to avoid the mold frame 17 shifting due to excessive looseness or damaging the mold frame 17 due to excessive tightness. When the drive assembly drives the mold frame 17 to rotate around its own axis, the push plate 16 can rotate synchronously around the drive end of the first electric push rod 15, always maintaining a tight fit with the outer wall of the mold frame 17. This does not hinder the rotation of the mold frame 17, but can continuously provide a stable clamping force, ensuring that the mold frame 17 is accurately positioned during rotation.

[0036] Furthermore, the drive assembly includes a support frame 11 rotatably mounted on one side of the top of the bracket 1 via a bearing. A first gear 12 is fixedly mounted on one end of the support frame 11, and a second gear 13 is meshed with the first gear 12. A first motor 14 is fixedly mounted on the top outer side of the bracket 1. The drive output end of the first motor 14 is connected to the drive shaft. The bracket 1 through which the drive shaft passes is fixedly connected to the central shaft of the second gear 13.

[0037] The first motor 14 on the top outer side of the bracket 1 is started. The output end of the first motor 14 transmits torque to the transmission shaft, which drives the second gear 13, which passes through the bracket 1 and is fixedly connected to itself, to rotate. Since the second gear 13 meshes with the first gear 12 fixed at one end of the abutment 11, the rotation of the second gear 13 is transmitted to the first gear 12 through tooth surface contact, causing the first gear 12 to drive the abutment 11 to rotate synchronously around its rotation mounting point at the top of the bracket 1. When the abutment 11 rotates, its inner sidewall is tightly fitted with the outer wall of the mold frame 17, thereby causing the mold frame 17 to rotate together with the abutment 11. Since the gear transmission has a fixed transmission ratio, by adjusting the speed of the first motor 14, the rotation speed of the second gear 13 and the first gear 12 can be precisely controlled, thereby achieving precise control of the rotation speed and angle of the mold frame 17, ensuring that each area of ​​the wax mold 18 receives uniform heating.

[0038] The lifting assembly includes a second electric push rod 21 fixedly installed at the bottom center of the workbench 2. Both sides of the workbench 2 are provided with through grooves, and limit rods 22 are slidably installed in the through grooves. The top of the limit rods 22 is fixedly connected to the bottom of the base box 23.

[0039] When it is necessary to adjust the docking position of the insert rod 25 and the wax mold 18, the second electric push rod 21 at the bottom of the workbench 2 is energized and activated. Its drive end extends and retracts in the vertical direction, driving the bottom box 23, which is fixedly connected to it, to rise and fall synchronously. During the rising and falling of the bottom box 23, the limiting rods 22 fixed on both sides of the bottom of the bottom box 23 always slide in the through groove at the corresponding position on the workbench 2. The through groove constrains the movement trajectory of the limiting rods 22, preventing the bottom box 23 from deviating horizontally during the rising and falling process. The sliding cooperation between the limiting rods 22 and the through groove further enhances the stability of the rising and falling of the bottom box 23, and avoids the bottom box 23 shaking, which would cause the insert rod 25 and the wax mold 18 port to misalign.

[0040] Preferably, the heating assembly includes a protrusion 26 fixedly connected to the top of the plug rod 25, a heating strip 27 fixedly installed on the protrusion 26 and one side of the outer wall of the plug rod 25, a wire fixedly connected to one end of the heating strip 27, and the wire passing through the side wall of the plug rod 25 and connected to an external power source.

[0041] After the insert rod 25 is inserted into the wax mold 18, the protrusion 26 on its top fits against the inner wall of the wax mold 18, so that the heating strip 27 fixed to the outer wall of the insert rod 25 and the surface of the protrusion 26 is in complete contact with the wax layer on the inner wall of the wax mold 18. The external power supply supplies power to the heating strip 27 through the wire passing through the side wall of the insert rod 25. After the heating strip 27 is powered on, it converts electrical energy into heat energy. The heat is directly transferred to the wax layer through the contact interface between the heating strip 27 and the wax layer, realizing targeted heating of the wax layer. According to the difference in melting point of the wax mold material, the heating temperature of the heating strip 27 can be changed by adjusting the output power of the external power supply: when the power is increased, the heating temperature rises, accelerating the melting of the wax layer; when the power is decreased, the heating temperature drops, avoiding excessive melting of the wax layer or damage to the mold, and ensuring that the wax layer melts evenly at a suitable temperature.

[0042] It should be noted that a top cover 24 is detachably installed on the top of the bottom box 23, and a collection cover 28 is provided on the outer side of the bottom of the insertion rod 25. The collection cover 28 is fixedly installed on the top of the top cover 24.

[0043] When maintenance is required on the insertion rod 25 and heating component, the removable top cover 24 on the top of the base box 23 can be directly removed to fully expose the insertion rod 25 and heating component inside the base box 23. After the maintenance operation is completed, the top cover 24 can be reinstalled to restore the function of the equipment without disassembling the entire base box 23, thus shortening the maintenance time. During the heating and melting of the wax layer by the heating component, the liquid wax drips down the inner wall of the wax mold 18 under the action of gravity and falls into the collection hood 28 fixed on the top of the top cover 24 and corresponding to the port of the wax mold 18. Since the adjacent collection hoods 28 are connected to each other through the conduit, the wax liquid in a single collection hood 28 can flow into other collection hoods 28 through the conduit, realizing the centralized collection of wax liquid from multiple sets of wax molds 18 and avoiding the wax liquid dripping onto the workbench 2 or equipment surface and causing pollution.

[0044] It should be noted that the reciprocating mechanism includes several inner rings 3 rotatably mounted on the bottom of the top cover 24 via bearings. A connecting frame 31 is fixedly mounted on the outer wall of the inner ring 3. An outer ring 32 is fixedly mounted on the other end of the connecting frame 31. Several transmission teeth 33 are fixedly mounted on the outer wall of the outer ring 32. The transmission teeth 33 on the outer sides of two adjacent outer rings 32 mesh. Several external teeth 34 are fixedly mounted on the inner wall of the outer ring 32. Several internal teeth 35 are fixedly mounted on the outer wall of the inner ring 3. A third gear 36 is provided between the outer ring 32 and the inner ring 3. The third gear 36 passes through the bottom of the top cover 24 and is fixedly connected to the bottom of the corresponding insertion rod 25.

[0045] An external power source drives one of the outer rings 32 to rotate around its own axis. Because the transmission teeth 33 on the outer walls of adjacent outer rings 32 mesh with each other, the rotating outer ring 32 drives all outer rings 32 to rotate synchronously through tooth surface meshing. When the outer ring 32 rotates, the outer teeth 34 fixed on its inner wall mesh with the third gear 36 between the outer ring 32 and the inner ring 3, driving the third gear 36 to rotate clockwise around its own axis. At this time, the heating component sweeps across one side of the inner wall of the wax mold 18 with the insertion rod 25 rotating clockwise. The inner ring 3 is fixedly connected to the outer ring 32 through the connecting bracket 31 and rotates synchronously with the outer ring 32. When the third gear 36 rotates to the area of ​​the inner ring 3, the inner teeth 35 on the outer wall of the inner ring 3 mesh with the third gear 36, driving the third gear 36 to rotate counterclockwise around its own axis until the third gear 36 completes half a revolution of counterclockwise rotation. By controlling the rotation angle of the outer ring 32, it is ensured that the heating component fully covers the inner wall of the wax mold 18 without any heating dead angles.

[0046] It should be noted that the internal teeth 35 extend from the top to the bottom along the axial direction of the inner ring 3, and the external teeth 34 extend from the bottom to the top along the axial direction of the outer ring 32.

[0047] During the rotation of the reciprocating mechanism driving the insertion rod 25, the third gear 36 will move slightly along the axial direction along with the movement of the outer ring 32 and the inner ring 3. Since the outer tooth 34 extends from the bottom to the top along the axial direction of the outer ring 32, the teeth of the third gear 36 are always engaged with the outer tooth 34 in the initial stage of axial movement, continuously driving the insertion rod 25 to rotate forward. When the third gear 36 moves axially to the top of the outer ring 32, its teeth just disengage from the outer tooth 34 and immediately engage with the inner tooth 35 of the inner ring 3. The tooth direction of the inner tooth 35 is opposite to that of the outer tooth 34, so that the third gear 36 instantly switches to the reverse state, and the meshing process is without gaps or interruptions, avoiding the insertion rod 25 from rotating and ensuring that the heating component smoothly sweeps across the inner wall of the wax mold 18, improving the uniformity of wax melting.

[0048] Example 2, refer to Figures 7 to 9 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a collection mechanism for a high-temperature alloy casting device for aerospace, which solves the problem of wax solution collection. It includes a collection mechanism, which is set on one side of the workbench 2. The collection mechanism is used to collect the heated wax solution. The drive component is located on one side of the collection mechanism and is used to drive the collection mechanism.

[0049] Specifically, the collection mechanism includes a sealing cylinder 46 fixedly installed on one side of the workbench 2. A sealing plug 45 is movably installed inside the sealing cylinder 46. A squeezing rod 44 is fixedly connected to the middle of one side of the sealing plug 45. Both ends of one side of the sealing cylinder 46 are connected to feed pipes 47. The other end of the feed pipe 47 is connected to the inner cavity of the corresponding collection hood 28. Two adjacent collection hoods 28 are connected through conduits. Both ends of the other side of the sealing cylinder 46 are connected to discharge pipes 48. One-way valves 49 are installed on both the discharge pipe 48 and the feed pipe 47. The flow direction of the one-way valve 49 of the discharge pipe 48 is introduced to the outside through the sealing cylinder 46, and the flow direction of the one-way valve 49 of the feed pipe 47 is introduced into the sealing cylinder 46 through the collection hood 28.

[0050] When the collecting mechanism is activated, external force drives the extrusion rod 44 to reciprocate along the axis of the sealing cylinder 46, causing the sealing plug 45 to slide synchronously within the inner cavity of the sealing cylinder 46. When the sealing plug 45 moves away from the feed pipe 47, the volume of the inner cavity of the sealing cylinder 46 increases, creating a negative pressure inside. At this time, the one-way valve 49 on the feed pipe 47 opens, and the one-way valve 49 on the discharge pipe 48 closes. The wax liquid concentrated in the collecting hood 28 is drawn into the inner cavity of the sealing cylinder 46 through the feed pipe 47 under the action of negative pressure. When the sealing... When the plug 45 moves toward the feed pipe 47, the volume of the inner cavity of the sealing cylinder 46 decreases, creating positive pressure inside. The one-way valve 49 of the feed pipe 47 closes, and the one-way valve 49 of the discharge pipe 48 opens. Under the action of positive pressure, the wax liquid in the sealing cylinder 46 is discharged through the discharge pipe 48 to the external recycling container. Adjacent collection hoods 28 are connected by conduits, which can collect the wax liquid from multiple collection hoods 28 into the same feed pipe 47, achieving efficient centralized recycling of the wax liquid. The sealing structure also prevents the wax liquid from leaking or evaporating.

[0051] Furthermore, the drive assembly includes a second motor 38 fixedly installed on one side of the inner wall of the base box 23. The drive output end of the second motor 38 is connected to the drive shaft. The other end of the drive shaft and the other end of the inner wall of the base box 23 are both equipped with couplings 4. Correspondingly, two couplings 4 are equipped with drive belts 41. One coupling 4 is fixedly connected to the central shaft of the fourth gear 37. The middle of the other coupling 4 passes through the bottom of the base box 23 and is fixedly connected to an eccentric disk 42. A drive arm 43 is rotatably installed on the outer wall of the eccentric disk 42. The other end of the drive arm 43 is rotatably connected to the other end of the extrusion rod 44.

[0052] The second motor 38 on the inner wall of the base box 23 is started. The motor drive output end transmits power to the transmission shaft, which drives the couplings 4 at both ends of the inner wall of the base box 23 to rotate synchronously. One of the couplings 4 is fixedly connected to the central shaft of the fourth gear 37. Its rotation directly drives the fourth gear 37 to rotate. The fourth gear 37 meshes with the transmission teeth 33 of the outer ring 32 of the reciprocating mechanism, thereby driving the reciprocating mechanism to operate. The middle part of the other coupling 4 passes through the bottom of the base box 23 and is fixedly connected to the eccentric disk 42. Its rotation drives the eccentric disk 42 to make a circular motion around the axis of the coupling 4. The rotation mounting point on the outer wall of the eccentric disk 42 generates a periodic displacement with the circular motion. Through the drive arm 43 rotatably connected to it, the circular motion is converted into the axial reciprocating motion of the extrusion rod 44, thereby driving the sealing plug 45 of the collection mechanism to slide.

[0053] The rest of the structure is the same as in Example 1. It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it.
