Description

Technical Field

[0001] The present application relates to the technical field of investment casting, and in particular to a wax pattern dewaxing device. Background Art

[0002] Investment casting is also known as lost wax casting. In the specific operation, wax is first used to make a wax model of the required casting parts. Then the slurry is applied to the wax model, and then gravel, sand and other materials are attached to the side of the slurry away from the wax model. After the gravel, sand and other materials are dried, they are placed in the hot water inside the dewaxing tank. After the wax model is melted, the mud mold formed by gravel, sand and other materials can be removed for subsequent processing.

[0003] By placing the wax model in the dewaxing pool, when the wax model melts into small wax blocks, the staff manually fishes out the wax blocks inside the dewaxing pool for subsequent use.

[0004] With respect to the above-mentioned related technologies, the staff manually collects the wax blocks inside the dewaxing tank, and the collection efficiency of the wax blocks is low. Summary of the invention

[0005] In order to improve the collection efficiency of melted wax blocks inside a dewaxing pool, the present application provides a wax mold dewaxing device.

[0006] The wax model dewaxing device provided in this application adopts the following technical solution:

[0007] A wax model dewaxing device comprises a dewaxing pool, a heating plate is provided in the dewaxing pool, the dewaxing pool is connected to a water inlet pipe, the dewaxing pool is also connected to a drain pipe, a support plate is provided above the dewaxing pool, the support plate is connected to a lifting assembly for driving the support plate to move up and down, a wax pushing plate is provided on the side of the support plate close to the dewaxing pool, a wax collecting assembly is also provided on the side of the support plate close to the dewaxing pool for collecting melted wax blocks inside the dewaxing pool, a driving assembly is also provided on the support plate for driving the wax collecting assembly to perform a wax collecting operation, and the driving assembly is connected to the wax pushing plate.

[0008] By adopting the above technical solution, when the wax model needs to be demolded, water is first injected into the dewaxing pool from the water inlet pipe, and then the water inside the dewaxing pool is heated by the heating plate, and the wax model is placed inside the dewaxing pool, and then the support plate is driven downward by the lifting assembly, and the support plate drives the wax pushing plate to move downward during the downward movement, and the wax pushing plate pushes the wax model into the water inside the dewaxing pool during the movement, and then the wax model is melted into a wax block inside the dewaxing pool;

[0009] The heating plate is then turned off, allowing the wax blocks inside the dewaxing pool to condense, and the wax collecting assembly is driven by the driving assembly to collect the wax blocks inside the dewaxing pool, thereby achieving rapid collection of the wax blocks inside the dewaxing pool and improving the efficiency of the staff in collecting the wax blocks inside the dewaxing pool.

[0010] Optionally, the wax collecting assembly includes two wax collecting frames arranged opposite to each other, and the side wall of each of the wax collecting frames can abut against the inner wall of the dewaxing pool, and the side of each of the wax collecting frames close to the support plate is slidably connected to the support plate, and no side walls are provided on the opposite sides of the two wax collecting frames, and each of the side walls of the wax collecting frames is provided with multiple leakage holes, and the driving assembly can drive the two wax collecting frames to move towards each other.

[0011] By adopting the above technical solution, when it is necessary to collect the wax blocks inside the dewaxing pool through the wax collecting assembly, the two wax collecting frames are driven by the driving assembly to move in a direction close to each other, so that the opposite surfaces of the two wax collecting frames are fitted. During the movement, the wax collecting frame collects the wax blocks inside the dewaxing pool to the middle position of the two wax collecting frames, and then the lifting assembly drives the support plate to be lifted, thereby driving the two wax collecting frames to be lifted. During the lifting process of the two wax collecting frames, since the side walls of the wax collecting frames are provided with leakage holes, the water inside the wax collecting frames can leak out from the leakage holes, so that the wax blocks are retained inside the wax collecting frames, thereby realizing the collection of the wax blocks inside the dewaxing pool.

[0012] Optionally, the bottom side wall of any one of the wax collecting frames is arranged to be gradually inclined downward from a side close to the other wax collecting frame to a side away from the other wax collecting frame.

[0013] By adopting the above technical solution, since the bottom side walls of the two wax collecting frames are inclined, the wax blocks collected by the wax collecting frames can be moved along the inclined direction of the bottom side walls of the wax collecting frames to one side close to one of the side walls of the wax collecting frames, thereby making it convenient for staff to collect the wax blocks inside the wax collecting frames.

[0014] Optionally, the wax pushing plate is made of a material with a density less than that of water, and the driving assembly includes a driving rod fixedly connected to the wax pushing plate, the driving rod passes through the support plate and is slidably connected to the support plate, and a plurality of driving tooth blocks are fixedly connected on opposite sides of the driving rod, and two driving gears are installed on both sides of the driving rod above the support plate, and a side of each driving gear close to the driving rod is meshed with a plurality of driving tooth blocks on one side of the driving rod, and each driving gear is meshed with a driving rack, and each driving rack is arranged parallel to the moving direction of the wax collecting frame during the wax collecting process, and the two driving racks are arranged in a one-to-one correspondence with the two wax collecting frames, and one side of each driving rack is connected to the corresponding wax collecting frame.

[0015] By adopting the above technical solution, when the support plate drives the wax pushing plate to move downward, since the wax pushing plate is made of a material with a density lower than that of water, when the wax pushing plate contacts water, the wax pushing plate moves upward, driving the driving rod to move upward. In the process of the driving rod moving upward, the driving gears on both sides are driven to rotate by multiple driving gear blocks on both sides. The rotation of the driving gear drives the driving rack to move. The movement of the driving rack drives the two wax collecting frames to move towards each other, thereby realizing the collection of wax blocks inside the dewaxing pool and facilitating the process of the staff moving the two wax collecting frames.

[0016] Optionally, a fixing component is also installed on the support plate to prevent the driving rod from moving downward.

[0017] By adopting the above technical solution, due to the presence of the fixed component, the driving rod is reduced to move downward under the action of gravity during the process of the support plate driving the two wax collecting frames to move upward, driving the two wax collecting frames to move away from each other, thereby reducing the occurrence of wax blocks falling between the two wax collecting frames.

[0018] Optionally, the fixing assembly includes a plurality of fixed ratchet blocks fixedly connected to one side of the driving rod, a fixed pawl is installed on the support plate, one side of the fixed pawl is meshed with the fixed ratchet block, the fixed pawl is rotatably connected to a fixed block on a side away from the driving rod, and a fixed sliding hole is opened on the support plate for the fixed block to be slidably inserted.

[0019] By adopting the above technical solution, when the support plate drives the two wax collecting frames to move upward, since the fixed pawl is engaged with the fixed ratchet block, the driving rod is difficult to move downward during the process of moving upward driven by the support plate, so that the relative surfaces of the two wax collecting frames can still remain in contact with each other during the process of moving upward with the support plate.

[0020] When the driving rod needs to move downward so that the two wax collecting frames move away from each other and collect the wax blocks between the two wax collecting frames, the fixed block is moved to the side away from the driving rod so that the fixed pawl no longer engages with the fixed ratchet block, thereby allowing the driving rod to move downward under the action of gravity. When the two wax collecting frames move away from each other driven by the driving rod, the wax blocks inside the two wax collecting frames can be collected.

[0021] Optionally, the side wall of the fixed block is slidably plugged with multiple plug-in blocks, a plug-in spring is connected between each plug-in block and the inner wall of the fixed block, and a plurality of plug-in holes for the plug-in blocks to be plugged in are opened on the side wall of the fixed sliding hole close to the driving rod.

[0022] By adopting the above technical solution, due to the cooperation of the plug-in block, the plug-in spring and the plug-in hole, when the fixed block moves to the side close to the driving rod, the plug-in block can be plugged into the plug-in hole driven by the plug-in spring, thereby fixing the position of the fixed block, and further making the fixed pawl more stable during the process of clamping the fixed ratchet block.

[0023] Optionally, the lifting assembly includes multiple lifting ropes connected to the support plate, each of the lifting ropes is provided with a fixed pulley on one side above the support plate, each of the lifting ropes is provided with a winding drum at one end passing through the fixed pulley, and each of the winding drums is provided with a lifting motor on one side for driving the winding drum to rotate.

[0024] By adopting the above technical solution, when it is necessary to drive the support plate to move, the lifting motor is started, and the lifting motor drives the lifting rope to move around the fixed pulley. The lifting rope drives the support plate to move during the movement, thereby realizing the process of driving the support plate to move up and down through the lifting motor.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. Through the cooperation of the wax collecting assembly, the support plate, the wax pushing plate and the driving assembly, the wax blocks inside the dewaxing pool can be collected, thereby facilitating the process of the staff to collect the wax blocks inside the dewaxing pool and speeding up the efficiency of the staff to collect the wax blocks inside the dewaxing pool;

[0027] 2. With the existence of the fixing assembly, when the support plate lifts the positions of the two wax collecting frames, the fixing assembly can limit the positions of the two wax collecting frames, and when it is necessary to collect the wax blocks inside the wax collecting frames, the fixing assembly can be opened to collect the wax blocks inside the two wax collecting frames;

[0028] 3. The lifting rope is driven by the lifting motor to move, and the lifting rope drives the support plate to move up and down, which facilitates the process of the staff to move the support plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1 -Attached Figure 5 This application is described in further detail.

[0036] The present application embodiment discloses a wax model dewaxing device, referring to Figure 1 , including a dewaxing pool 1, a notch is provided in the middle of the upper side of the dewaxing pool 1. The upper end of one of the side walls of the dewaxing pool 1 is connected with a water inlet pipe 11, and a water inlet valve 111 is installed at the part of the water inlet pipe 11 outside the dewaxing pool 1, and the lower end of the side wall of the dewaxing pool 1 away from the water inlet pipe 11 is connected with a drain pipe 12, and a drain valve 121 is installed at the part of the drain pipe 12 outside the dewaxing pool 1.

[0037] Reference Figure 2 and Figure 3 A heating plate 13 for heating the water inside the dewaxing tank 1 is installed on the bottom wall of the dewaxing tank 1.

[0038] A support plate 2 is provided above the dewaxing tank 1, and the support plate 2 is arranged horizontally. A lifting assembly 3 for driving the support plate 2 to move up and down is connected to the upper surface of the support plate 2, and the side wall of the support plate 2 can slide against the inner wall of the dewaxing tank 1 during the movement. A wax push plate 21 is also provided in the middle position of the lower surface of the support plate 2.

[0039] The lower surface of the support plate 2 is also provided with a wax collecting assembly 4, which can collect the wax blocks dissolved in the dewaxing tank 1. The support plate 2 is also provided with a driving assembly 5, which is used to drive the wax collecting assembly 4 to move so as to collect the wax blocks in the dewaxing tank 1. The driving assembly 5 is connected to the wax pushing plate 21.

[0040] When the mold needs to be dewaxed, open the water inlet valve 111, close the drain valve 121, and inject a certain amount of water into the dewaxing pool 1 from the water inlet pipe 11, and then heat the water inside the dewaxing pool 1 through the heating plate 13. Then, place the wax mold inside the dewaxing pool 1, and drive the support plate 2 to move downward through the lifting component 3. During the downward movement of the support plate 2, the wax pusher plate 21 is driven to move downward. During the downward movement of the wax pusher plate 21, the wax mold is driven to sink into the water inside the dewaxing pool 1. Since the heating plate 13 heats the water inside the dewaxing pool 1, when the wax mold enters the dewaxing pool 1, the wax mold gradually melts into wax blocks, and then the wax collecting component 4 is driven by the driving component 5 to collect the wax blocks in the dewaxing pool 1, thereby realizing the collection of wax blocks.

[0041] The wax collecting assembly 4 is driven by the driving assembly 5 to collect the wax blocks, thereby increasing the efficiency of wax block collection and further increasing the overall production efficiency.

[0042] Reference Figure 2 and Figure 4 The wax collecting assembly 4 includes two wax collecting frames 41, and the two wax collecting frames 41 are arranged opposite to each other on the lower surface of the support plate 2. The side of each wax collecting frame 41 close to the inner wall of the dewaxing pool 1 is in contact with the inner wall of the dewaxing pool 1. No side walls are provided on the opposite surfaces of the two wax collecting frames 41. Two T-shaped sliders 42 are fixedly connected to the upper surfaces of the two oppositely arranged side walls of each wax collecting frame 41, and there is a certain distance between the two sliders 42 connected to the side walls of the same wax collecting frame 41. Two wax collecting holes 22 that are arranged opposite to each other and penetrate the support plate 2 are provided on the support plate 2. Each slider 42 is plugged into the inside of an adjacent wax collecting hole 22, and the sliders 42 connected to different wax collecting frames 41 can be located inside the wax collecting hole 22 and slide in a direction close to each other.

[0043] Each wax collecting frame 41 has multiple side walls with water leakage holes 43. The driving assembly 5 can drive the two wax collecting frames 41 to move toward each other, so that the side walls of the two wax collecting frames 41 on opposite sides are attached to each other, so that a cavity is formed in the middle of the two wax collecting frames 41.

[0044] When the wax blocks are dissolved inside the dewaxing pool 1, the heating plate 13 is turned off, so that the wax blocks inside the dewaxing pool 1 are condensed, and then the two wax collecting frames 41 are driven by the driving component 5 to move towards each other. When the two wax collecting frames 41 are in contact with each other, the wax blocks in the dewaxing pool 1 can be collected in the cavity formed between the two wax collecting frames 41, thereby realizing the collection of the wax blocks inside the dewaxing pool 1.

[0045] The bottom side wall of each wax collecting frame 41 is inclined, and the bottom side wall of any wax collecting frame 41 is gradually inclined downward from a side close to another wax collecting frame 41 to a side away from another wax collecting frame 41 .

[0046] Since the bottom side wall of the wax collecting frame 41 is set as an inclined surface, when the wax block is located below the wax collecting frame 41, the wax block can move along the inclined surface of the lower surface of the bottom side wall of the wax collecting frame 41 to the middle position of the two wax collecting frames 41 during the upward movement to be collected. When the wax block is collected between the two wax collecting frames 41, the wax block can move along the inclined surface of the upper surface of the bottom side wall of the wax collecting frame 41 to the edge of the bottom side wall of the wax collecting frame 41, so that it is more convenient for the staff to collect.

[0047] Reference Figure 2 The wax pushing plate 21 can be made of a variety of materials with a density less than that of water. In this embodiment, the wax pushing plate 21 is made of plastic that can float in water.

[0048] The driving assembly 5 includes a vertically arranged driving rod 51, the lower end of which passes through the middle position of the supporting plate 2 and is slidably connected to the supporting plate 2. One end of the driving rod 51 passing through the supporting plate 2 is fixedly connected to the upper surface of the wax pushing plate 21.

[0049] The driving assembly 5 further includes a plurality of driving gear blocks 511 fixedly connected to a side of the driving rod 51 close to each wax collecting frame 41, and the plurality of driving gear blocks 511 are evenly arranged along the length direction of the driving rod 51. Two driving gears 52 are provided on the support plate 2, and the two driving gears 52 are correspondingly arranged with two rows of driving gear blocks 511. One side of each driving gear 52 is meshed with a corresponding row of driving gear blocks 511.

[0050] A mounting shaft 521 passes through and is rotatably connected to the middle of each driving gear 52. Both ends of each mounting shaft 521 are fixedly connected to mounting rods 522, and the mounting rods 522 are vertically arranged. One end of each mounting rod 522 away from the mounting shaft 521 is fixedly connected to the upper surface of the support plate 2.

[0051] A driving plate 53 is fixedly connected to the upper surface of the side wall of each wax collecting frame 41 that is not connected to the slider 42. Two sliding holes 23 are provided on the support plate 2, and the two sliding holes 23 are arranged one-to-one with the two driving plates 53. Each driving plate 53 is plugged into the corresponding sliding hole 23 and can move toward the side close to the driving rod 51. A driving rack 54 is fixedly connected to the side of each driving plate 53 close to the driving gear 52. Each driving rack 54 is horizontally arranged, and the side of each driving rack 54 away from the driving plate 53 is meshed with the adjacent driving gear 52. The two driving racks 54 are staggered on both sides of the driving rod 51, so that the two driving racks 54 can move staggeredly when the two driving plates 53 move toward each other.

[0052] In the process of pushing the wax model into the dewaxing pool 1 by the wax pushing plate 21, since the wax pushing plate 21 is made of plastic that can float on the water surface, the wax pushing plate 21 gradually moves downwards during the downward movement of the support plate 2. After the wax pushing plate 21 contacts the water surface, the wax pushing plate 21 moves upwards relative to the support plate 2 that continues to move downwards, thereby driving the driving rod 51 to move upwards. During the upward movement of the driving rod 51, the two driving gears 52 are driven to rotate. During the rotation, the two driving gears 52 drive the meshing driving racks 54 to move. During the movement of the driving racks 54, the driving plate 53 and the wax collecting frame 41 are driven to move, thereby fitting the opposite surfaces of the two wax collecting frames 41. Then, the wax blocks inside the dewaxing pool 1 are collected in the cavities inside the two wax collecting frames 41, thereby realizing the collection of the wax blocks.

[0053] And because the bottom side walls of the wax collecting frames 41 are set as inclined surfaces, the wax blocks inside the two wax collecting frames 41 can move to the side of the bottom of the wax collecting frames 41 close to the side walls, so that when the support plate 2 is lifted upward by the lifting assembly 3, the driving rod 51 moves downward, and when the two wax collecting frames 41 move away from each other, the wax blocks inside the wax collecting frames 41 are difficult to fall off.

[0054] Reference Figure 4 and Figure 5 A fixing assembly 6 is also provided on one side of the driving rod 51, and the fixing assembly 6 can prevent the driving rod 51 from moving downward.

[0055] Due to the presence of the fixing component 6, when the two wax collecting frames 41 collect the wax blocks inside the dewaxing pool 1, when the lifting component 3 is started to drive the support plate 2 to move upward, the driving rod 51 is difficult to move downward due to the presence of the fixing component 6. As a result, during the upward movement of the two wax collecting frames 41, the relative surfaces of the two wax collecting frames 41 always remain in contact with each other, so that the wax blocks between the two wax collecting frames 41 can be collected more stably.

[0056] The fixing assembly 6 includes a plurality of fixed ratchet blocks 61 fixedly connected to one side of the driving rod 51, and the end of each fixed ratchet block 61 is tilted downward. A fixed pawl 62 is also provided on the support plate 2, and one side of the fixed pawl 62 can be engaged with the fixed ratchet block 61, and the side of the fixed pawl 62 close to the fixed ratchet block 61 is tilted upward. The end of the fixed pawl 62 away from the fixed ratchet block 61 is rotatably connected to a fixed block 63.

[0057] The support plate 2 is provided with a fixed sliding hole 24 for the fixed block 63 to be inserted and slided. The fixed sliding hole 24 is opened along a side close to the driving rod 51 to a side close to one of the driving plates 53. The fixed block 63 is inserted into the fixed sliding hole 24 and slides against the inner wall of the fixed sliding hole 24 along the length direction of the fixed sliding hole 24.

[0058] When the driving rod 51 moves upward, a plurality of fixed ratchet blocks 61 pass through the fixed pawl 62 in sequence and drive the fixed pawl 62 to rotate. When the support plate 2 moves upward driven by the lifting assembly 3, the fixed ratchet block 61 engages with the fixed pawl 62, making it difficult for the driving rod 51 to move downward under the action of gravity. When the lower part of the two wax collecting frames 41 is supported to collect the wax blocks inside the two wax collecting frames 41, the fixed block 63 is moved to the side away from the driving rod 51, so that the fixed pawl 62 is no longer engaged with the fixed ratchet block 61, so that the driving rod 51 can move downward. In the process of the driving rod 51 moving downward, the two wax collecting frames 41 can be driven to move away from each other, so that the staff can collect the wax blocks inside the two wax collecting frames 41.

[0059] Holes are provided on the two opposite side walls of the fixed block 63, and a plug-in block 631 is slidably inserted in each hole. A plug-in spring 632 is fixedly connected to one end of each plug-in block 631 located in the hole, and one end of each plug-in spring 632 away from the plug-in block 631 is fixedly connected to the inner wall of the hole of the fixed block 63. Plug-in holes 241 are provided on the two opposite inner walls of the fixed sliding hole 24. The two plug-in holes 241 are arranged one-to-one with the two plug-in blocks 631, and the two plug-in holes 241 can be inserted into the corresponding plug-in blocks 631 when the fixed pawl 62 is engaged with the fixed ratchet block 61. The side of each plug-in block 631 close to the extension direction of the fixed sliding hole 24 is inclined from the side close to the plug-in spring 632 to the side away from the plug-in spring 632, and gradually to the side away from the fixed sliding hole 24 and away from the extension direction of the driving rod 51.

[0060] When the fixed block 63 moves toward the side close to the driving rod 51, after the fixed block 63 moves to the side close to the driving rod 51, the two plug-in blocks 631 are plugged into the corresponding plug-in holes 241, thereby determining the position of the fixed block 63, so that the fixed pawl 62 can be more stable when clamping the fixed ratchet block 61, and when the fixed block 63 needs to move to the side away from the driving rod 51, since one side of each clamping block is set as an inclined surface, during the movement of the fixed block 63, the inclined surface on one side of the plug-in block 631 abuts against the inner wall of the plug-in hole 241, so that the plug-in block 631 can be retracted into the hole of the fixed block 63, thereby realizing the movement process of the fixed block 63.

[0061] Reference Figure 2 and Figure 3 , both ends of the upper surface of the support plate 2 are fixedly connected with a connecting frame 25. The lifting assembly 3 includes a lifting rope 31 connected to each connecting frame 25. A fixed pulley 32 is sleeved on one side above each lifting rope 31, and a rotating shaft 321 is passed through and rotatably connected to the middle of each fixed pulley 32, and a connecting rod 33 is fixedly connected to the end of each rotating shaft 321, and one end of each connecting rod 33 away from the rotating shaft 321 is fixedly connected to the upper surface of the side wall of the dewaxing tank 1. One end of each lifting rope 31 passing through the fixed pulley 32 is fixedly wound with a winding drum 34. A lifting motor 35 is provided on one side of each winding drum 34. The output shaft of each lifting motor 35 passes through the middle position of the adjacent winding drum 34 and is fixedly connected to the winding drum 34. The side of each lifting motor 35 close to the side wall of the dewaxing tank 1 is fixedly connected to the side wall of the dewaxing tank 1.

[0062] When the support plate 2 needs to be lifted, the two lifting motors 35 are started at the same time. The two lifting motors 35 drive the two winding drums 34 to rotate. The two winding drums 34 gather the two lifting ropes 31. The two lifting ropes 31 lift the support plate 2 during the gathering process, thereby driving the support plate 2 to move upward.

[0063] The implementation principle of a wax model dewaxing device in the embodiment of the present application is as follows: when the wax model needs to be melted, water is injected into the dewaxing pool 1 through the water inlet pipe 11, and the water inside the dewaxing pool 1 is heated by the heating plate 13. Then the wax model is placed inside the dewaxing pool 1, and then the two lifting motors 35 are started to drive the support plate 2 to move downward. During the downward movement of the support plate 2, the wax pushing plate 21 is driven to move downward, pushing the wax model into the dewaxing pool 1.

[0064] After the wax pattern melts inside the dewaxing tank 1, the heating plate 13 is turned off, so that the wax pattern inside the dewaxing tank condenses into wax blocks. Then, as the wax pushing plate 21 moves upward, the two wax collecting frames 41 are driven to move toward the middle, so that the wax blocks inside the dewaxing tank 1 are collected in the middle position of the two wax collecting frames 41.

[0065] Then, the lifting assembly 3 is started to lift the support plate 2 to the top of the dewaxing tank 1, the fixed block 63 is moved to the side away from the driving rod 51, and the middle position below the two wax collecting frames 41 is received, so as to realize the collection of wax blocks.

[0066] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
