[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] A Chinese patent with publication number CN116748469B discloses a steam dewaxing kettle, including a steam generator; a dewaxing kettle is installed on the steam generator; a liquid inlet pipe is connected to the steam generator, and a liquid discharge pipe and an exhaust pipe are connected to the dewaxing kettle, and a waste heat utilization mechanism matching the liquid inlet pipe, the liquid discharge pipe and the exhaust pipe is arranged on the outer side of the steam generator; the waste heat utilization mechanism includes a liquid treatment box, the upper end of the liquid treatment box is connected to a gas treatment box matching the exhaust pipe, and a plurality of evenly distributed heat exchange plates are connected between the middle part of the liquid treatment box and the gas treatment box. This scheme facilitates the recovery of heat from waste gas and waste liquid for preheating of liquid inlet, increases the temperature of water input into the steam dewaxing kettle, reduces the energy consumption when heating water to steam, and easily ensures full utilization of the heat of waste liquid and waste gas.

[0004] In the current prior art, when the wax mold is dewaxed, the mold is melted into small wax blocks, and the wax blocks inside the dewaxing pool are fished out manually by staff. In the process of manually fishing out the wax blocks, the staff usually use a brush or a stick, which can easily break the complete wax blocks and leave wax residues. The staff also needs to process it bit by bit, which is very time-consuming.

[0005] To this end, the present invention provides a wax pattern dewaxing device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

When the bottom of the cover tube contacts the annular opening in the containing box, the steam flow outlet on the gas blocking rod slides to adapt to the inner wall of the steam flow tube. At this time, the steam in the steam kettle will flow out to operate on the wax mold in the containing box, so as to prevent the steam from flowing out continuously without control when the operation is completed, which will not only affect the production but also easily scald the operators, thereby achieving the effect of blocking air.

When the barrier of the cover tube completely enters the annular opening, the two fit tightly, and the wax mold placed in the circular opening is inside the cover tube. The motor drives the containing boxes on the two push arms to slide in and out inside the device through the push plate, which is convenient for operation, and the sliding rod maintains the stability of the two push arms when sliding.

[0013] Preferably, a wax suction box is symmetrically fixedly installed on the outer wall of the machine wall, and the inner wall of the wax suction box is fixedly connected to the outer wall of the wax flow tube. A horizontal tube is arranged inside the wax suction box, and both ends of the horizontal tube are fixedly connected to one end of the wax flow tube. A lower suction tube is fixedly installed on the outer wall of the horizontal tube. There are three lower suction tubes, and the outer wall of the lower suction tube passes through the inner wall of the wax suction box.

[0019] 1. A wax model dewaxing device described in the present invention drives the containing box on the two push arms to slide into the interior of the device through a motor via a push plate, and the telescopic cylinder drives the cover tube to slide downward in the compressed air valve via a connecting frame plate. When the lower edge of the cover tube completely slides down to fit the inner wall of the annular opening in the containing box, the cover tube and the annular opening in the containing box form a sealed space. At the same time, the telescopic cylinder drives the gas blocking rod to slide in the steam flow tube. When the bottom of the cover tube contacts the annular opening in the containing box, the steam flow outlet on the gas blocking rod slides to fit the inner wall of the steam flow tube. The steam in the steam kettle flows out to operate on the wax model in the containing box, thereby preventing the steam from flowing out uncontrollably when the operation is completed, which not only affects the production but also easily scalds the operators, thereby achieving the effect of melting wax.

[0020] 2. The wax model dewaxing device described in the present invention, by pressing a button, the suction fan performs air extraction, and the wax inlet head of the wax extractor is aimed at the wax particles. The wax particles in the wax model will enter the wax storage box through the wax flow tube driven by the wind, and then fall on the wax partition plate. In the traditional process, the operators basically brush them off with a brush. During the brushing process, it is necessary to apply gentle force, otherwise the internal surface of the wax model is easily damaged, and the swept wax particles are scattered in the air and are not easy to collect. The use of air suction can not only save the workers' physical strength, but also avoid damage to the inside of the wax model, thereby achieving the effect of processing the wax particles.

[0033] During operation, in the prior art, when the wax model is dewaxed, the model is melted into small wax blocks, and the wax blocks inside the dewaxing pool are fished out manually by the staff;

[0034] By placing the wax model that needs to be dewaxed into the annular opening in the containing box, the cover tube 12 and the annular opening in the containing box form a sealed space, and the steam kettle 5 supplies hot steam to the inside of the air compressor 7 through the steam flow pipe 10. Then the air compressor 7 presses the introduced hot steam into the sealed space formed by the cover tube 12 and the containing box to melt the wax in the wax model.

[0035] like Figure 3 to Figure 4 As shown, a telescopic cylinder 8 is fixedly installed on the top of the inner wall of the machine wall 1, and a connecting frame plate 11 is fixedly installed on the output shaft of the telescopic cylinder 8. The outer walls of the two groups of cover tubes 12 are fixedly connected to the outer wall of the connecting frame plate 11. A gas blocking rod 13 is fixedly installed on the top of the connecting frame plate 11. There are two groups of gas blocking rods 13. The outer wall of the gas blocking rod 13 is slidably connected to the inner wall of the steam flow pipe 10. A steam flow port is opened on the inner wall of the gas blocking rod 13. The size of the steam flow port opened on the inner wall of the gas blocking rod 13 is adapted to the inner diameter flow width of the steam flow pipe 10.

[0036] During operation, the telescopic cylinder 8 drives the cover tube 12 to contact the containing box, and at the same time, the telescopic cylinder 8 drives the gas blocking rod 13 to slide in the steam flow tube 10. When the bottom of the cover tube 12 contacts the annular opening in the containing box, the steam flow opening on the gas blocking rod 13 slides to match the inner wall of the steam flow tube 10. At this time, the steam in the steam kettle 5 will flow out to operate the wax mold in the containing box, preventing the steam from flowing out uncontrollably when the operation is completed, which will not only affect production but also easily scald the operators.

[0037] like Figures 3 to 5As shown, a motor 9 is arranged inside the machine wall 1, and a push plate 28 is symmetrically fixedly installed on the output shaft of the motor 9, and push arms 14 are fixedly installed on the outer walls of the two push plates 28, and a slide bar 15 is symmetrically fixedly installed between the push arms 14, and three containing boxes are fixedly installed on the outer walls of the push arms 14, and a circular opening and an annular groove are opened inside the three containing boxes, and the circular opening contains the wax mold, and the annular opening fits with the wall of the cover tube 12. When the wall of the cover tube 12 completely enters the annular opening, the two are tightly fitted, and the wax mold placed in the circular opening is inside the cover tube 12;

[0038] During operation, the motor 9 drives the containing boxes on the two push arms 14 to slide in and out of the device through the push plate 28, which is convenient for operation. The slide bar 15 maintains the stability of the two push arms 14 during sliding.

[0039] like Figures 3 to 5 As shown, the outer wall of the push arm 14 is symmetrically mounted with a shaft 16, the inner wall of the machine wall 1 is provided with a slide groove 26, the outer wall of the shaft 16 is slidably connected with the inner wall of the slide groove 26, and the inner wall of the machine wall 1 is provided with a slide opening 29;

[0040] During operation, the motor 9 drives the shaft 16 to slide in the slide groove 26 . The slide groove 26 provides a path for the two push arms 14 to slide. The setting of the slide opening 29 facilitates the push arms 14 to slide out and in.

[0041] like Figures 3 to 6 As shown, a suction fan 18 is fixedly installed at the bottom of the machine wall 1, a wax extraction pipe 19 is fixedly installed on the outer wall of the suction fan 18, a wax storage box 2 is symmetrically fixedly installed on the outer wall of the machine wall 1, and a wax flow pipe 4 is symmetrically installed on the outer wall of the wax storage box 2;

[0042] When working, the suction fan 18 performs air extraction through the wax extraction pipe 19, and the wax particles enter the wax storage box 2 through the wax flow pipe 4 driven by the wind, and the wax particles are extracted.

[0043] like Figures 3 to 6 As shown, a wax suction box 30 is symmetrically fixedly installed on the outer wall of the machine wall 1, and the inner wall of the wax suction box 30 is fixedly connected to the outer wall of the wax flow tube 4. A transverse tube 6 is arranged inside the wax suction box 30, and both ends of the transverse tube 6 are fixedly connected to one end of the wax flow tube 4. A lower suction tube 21 is fixedly installed on the outer wall of the transverse tube 6. There are three lower suction tubes 21, and the outer wall of the lower suction tube 21 passes through the inner wall of the wax suction box 30;

[0044] During operation, the wax particles enter the transverse tube 6 through the lower suction tube 21, and then enter the wax storage box 2 through the transverse tube 6 through the wax flow tube 4, providing a path for the flow of the wax particles.

[0045] like Figure 6 to Figure 7As shown, a conversion elbow 25 is fixedly installed at the bottom of the lower extraction tube 21, a button 24 is slidably connected to the inner wall of the conversion elbow 25, and a wax extractor 23 is fixedly installed on the outer wall of the button 24;

[0046] When working, the button 24 is pressed to slide on the conversion elbow 25, and the wax extractor 23 will absorb the wax particles to play a control role.

[0047] like Figure 6 to Figure 7 As shown, a rack rod 20 is fixedly installed on the inner wall of the machine wall 1, and a storage platform 22 is fixedly installed on the top of the rack rod 20;

[0048] During operation, the storage platform 22 on the rack 20 is convenient for placing the wax extractor 23 .

[0049] like Figures 3 to 6 As shown, a wax partition plate 17 is fixedly installed on the inner wall of the wax storage box 2;

[0050] During operation, after the wax particles are drawn into the wax storage box 2, the wax particles fall steadily on the wax partition plate 17. The installation of the wax partition plate 17 prevents the wax particles from being sucked into the fan 18 by the wind, thereby avoiding blockage.

[0051] like Figure 1 to Figure 2 As shown, a leg frame 3 is fixedly installed at the bottom of the machine wall 1;

[0052] During operation, when the device is operating, the leg frame 3 can provide good support for the device and stabilize the stability of the body.

[0053] Working principle: When in use, put the wax model that needs to be dewaxed into the annular opening in the containing box. After the placement is completed, the motor 9 drives the containing box on the two push arms 14 to slide into the device through the push plate 28. When sliding to a certain position, the motor 9 stops operating, and then the telescopic cylinder 8 drives the cover tube 12 to slide downward in the air compression valve 7 through the connecting frame plate 11. When the lower edge of the cover tube 12 completely slides down to fit the inner wall of the annular opening in the containing box, the telescopic cylinder 8 stops operating. At this time, the cover tube 12 and the annular opening in the containing box form a sealed space. While the telescopic cylinder 8 is operating, the steam kettle 5 supplies heat to the inside of the air compression valve 7 through the steam flow pipe 10. The steam is then compressed by the air compression valve 7 into the sealed space formed by the cover tube 12 and the containing box to melt the wax in the wax model. The air blocking rod 13 inserted into the steam flow tube 10 plays a role in blocking the air. When the telescopic cylinder 8 drives the cover tube 12 to contact the containing box, the telescopic cylinder 8 also drives the air blocking rod 13 to slide in the steam flow tube 10. When the bottom of the cover tube 12 contacts the annular opening in the containing box, the steam flow opening on the air blocking rod 13 slides to match the inner wall of the steam flow tube 10. At this time, the steam in the steam kettle 5 will flow out to operate on the wax model in the containing box, so as to prevent the steam from being uncontrolled and flowing out when the operation is completed. The continuous outflow affects the production and is also very likely to scald the operators. When the wax melting is completed, the telescopic cylinder 8 drives the cover tube 12 and the gas blocking rod 13 to move up, the gas blocking rod 13 blocks the steam flow tube 10, and the cover tube 12 is separated from the containing box. When the telescopic cylinder 8 slides to a certain position, it stops operating, and the motor 9 drives the two push arms 14 to slide out of the device through the sliding port 29. When sliding out, the staff takes out the wax mold in the containing box, and then replaces it with another wax mold for wax melting. The staff of the taken out wax mold stirs the wax that has been melted into wax blocks inside, and the stirred wax blocks are placed aside for easy recycling. When the wax blocks are broken into small pieces or there is residue in the wax mold When the workers cannot move the smaller wax particles, they pick up the wax extractor 23 and press the button 24, the suction fan 18 will start the exhaust process, and the wax inlet head of the wax extractor 23 is aimed at the wax particles. The wax particles in the wax mold will enter the wax storage box 2 through the wax flow tube 4 under the drive of the wind, and then fall on the wax partition board 17. In the traditional process, the workers basically use a brush to brush them off. During the brushing process, it is necessary to apply gentle force, otherwise it is easy to damage the internal surface of the wax mold, and the swept wax particles are scattered in the air and are not easy to collect. The use of air suction can not only save the workers' physical strength, but also avoid damage to the inside of the wax mold, so as to achieve the effect of processing wax particles. At this point, the device operation is completed.
