Description

Technical Field

[0001] This invention relates to the field of casting wax technology, specifically to a continuous low-temperature wax precision casting mechanism. Background Technology

[0002] Low-temperature wax refers to wax oil whose temperature cannot exceed 70 degrees Celsius when poured. The finished wax has a white frost on its body. In the low-temperature wax casting process, the wax oil needs to be poured into the mold to form the wax. The wax oil cools and solidifies in the mold. Because the wax oil solidifies quickly, the formed wax block needs to be quickly removed from the mold so that the mold can be quickly recycled and the casting function can be achieved.

[0003] In the process of low-temperature wax casting, the mold needs to be recycled. Generally, the mold needs to be manually placed at the wax outlet to receive the wax. This is not only inefficient, but also prone to errors in mold placement, resulting in the wax not dripping accurately into the mold and wasting the wax. Therefore, a continuous low-temperature wax precision casting mechanism is proposed to solve the above problems. Summary of the Invention

[0012] Furthermore, a U-shaped strip is slidably installed at one end of the hollow shell, and an arc groove is formed inside the U-shaped strip. A groove is formed inside the hollow shell, and a cylindrical rod is fixedly installed inside the groove. A slider is slidably installed on the cylindrical rod, and one end of the slider is fixedly installed on the U-shaped strip.

[0013] Based on the aforementioned scheme, a rotating shaft is rotatably installed inside the hollow shell, and the rotating shaft is located on the lower side of the U-shaped strip.

A spring is fixedly installed at one end of the block, and the other end of the spring is fixedly installed on the inner wall of the through groove.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a continuous low-temperature wax precision casting mechanism, which has the following beneficial effects:

[0018] 1. Wax oil is poured into the injection tank through the guide pipe, thereby achieving the purpose of precise casting of low-temperature wax. The electric push rod drives the moving plate to move downward, which in turn drives the guide pipe to move downward close to the square frame and the injection tank, thereby improving the pouring accuracy of wax oil. The controller controls the working time of the solenoid valve to adjust the output of wax oil, so as to accurately control the casting of low-temperature wax. The solenoid valve is activated to pour wax oil into the injection tank. After the wax oil is poured, the controller controls the solenoid valve to close.

[0019] 2. The cylindrical disk is rotated and adjusted by a stepper motor to facilitate the pouring of the next injection tank. When the controller controls the electric push rod to close, it simultaneously controls the stepper motor to open. The stepper motor drives the cylindrical disk to rotate and move an angle, thereby aligning the next injection tank with the guide pipe. This facilitates uninterrupted low-temperature wax casting and improves the efficiency of the casting process.

[0020] 3. The movement of inclined block one compresses inclined block two, thereby pushing the limiting rod to move into the limiting hole. The moving plate moves downward, driving the U-shaped rod downward through the connecting rod. The U-shaped rod moves downward, driving inclined block two downward. Inclined block one and inclined block two are attached to each other, with one end being inclined. The downward movement of inclined block two compresses inclined block one through the inclined surface, causing inclined block one to move horizontally. The horizontal movement of inclined block one drives the limiting rod to move and insert into the limiting hole, thereby helping to fix the position of the cylindrical disk.

[0021] 4. The electric push rod moves the rack, which in turn drives the feed wheel to rotate and pull the U-shaped strip, thus realizing the feeding function of the low-temperature wax. The push rod moves, which drives the rack through the bar rod. The rack moves, which drives the gear to rotate. At the same time, the gear rotates, which drives the rope wheel to rotate through the rotating shaft. The rotation of the rope wheel drives the magnetic block to move and separate from the iron bar. The rotation of the rope wheel winds up the pull rope, which in turn pulls one end of the pull rope downward. The pull rope pulls the U-shaped strip downward. The U-shaped strip moves downward, which pulls the L-shaped rod downward. The L-shaped rod moves downward along the square block and stretches the spring, causing the spring to generate elastic force. The downward movement of the L-shaped rod pushes the T-shaped push block to move, thus pushing the solidified low-temperature wax to the outside of the square frame. The push rod moves and pushes the low-temperature wax to separate from the T-shaped push block, completing the rapid feeding of the low-temperature wax.

[0022] 5. The spring force facilitates the movement and reset of the T-shaped push block. The push rod continues to move, driving the rack to move, which in turn drives the gear to rotate in the opposite direction. The gear's reverse rotation drives the rope wheel to rotate in the opposite direction through the rotating shaft, causing the magnetic block to move and separate from the iron bar. This facilitates the reverse rotation of the gear and rope wheel. The reverse rotation of the rope wheel causes the pull rope to unfold. Under the action of the spring force, the T-shaped push block moves and resets, driving the L-shaped rod and U-shaped bar to move and reset in the opposite direction. At this time, the addition of wax oil into the injection tank by the guide tube ends. The stepper motor rotates at a certain angle to facilitate pushing the next L-shaped rod into the U-shaped bar, thus facilitating the ejection of the low-temperature wax from the next injection tank.

[0032] Reference Figures 1-7A continuous low-temperature wax precision casting mechanism includes a hollow shell 1, a stepper motor 2, a cylindrical disk 3, a sprue 4, and a square frame 5. The cylindrical disk 3 is rotatably mounted inside the hollow shell 1. The stepper motor 2 is mounted at one end of the hollow shell 1, extending into the hollow shell 1 and connecting to the cylindrical disk 3. The stepper motor 2 facilitates the rotation of the cylindrical disk 3 at a certain angle, ensuring that the guide tube 29 is always vertically aligned with one of the sprue 4. A controller 38 is mounted at one end of the hollow shell 1 via screws, and the controller 38 is electrically connected to the stepper motor 2. The controller 38 is designed to easily control the operation of the stepper motor 2. Two or more sprue 4 are evenly machined on the annular side of the cylindrical disk 3. The design of the sprue 4 facilitates... To facilitate the collection of wax oil and its solidification within the injection tank 4, two or more square frames 5 are evenly welded to the annular side of the cylindrical disk 3, and these square frames 5 are aligned with the injection tank 4. The design of the square frames 5 facilitates the casting of low-temperature waxes of different sizes. A support frame 24 is welded to one end of the hollow shell 1, and an electric push rod 25 is bolted to the top of the support frame 24. This design facilitates the fixed installation of the electric push rod 25. The electric push rod 25 is electrically connected to the controller 38, and a movable plate 26 is bolted to the top of the electric push rod 25. A conveying hose 27, a solenoid valve 28, and a guide pipe 29 are installed on the top of the movable plate 26. One end of the conveying hose 27 is connected to an external wax oil conveying device, thus facilitating the collection of wax oil. Continuous delivery is achieved through the design of solenoid valve 28, which facilitates the periodic dripping of wax oil. Solenoid valve 28 is electrically connected to controller 38. A conveying hose 27 and a guide pipe 29 are respectively installed at both ends of solenoid valve 28. The guide pipe 29 is designed to facilitate the delivery of wax oil into the filling tank 4. The bottom end of the guide pipe 29 passes through the moving plate 26 and is vertically aligned with one of the filling tanks 4. A square rod 32 is bolted inside the hollow shell 1. Two limiting rods 39 are symmetrically slidably installed at the end of the square rod 32 away from the cylindrical disk 3. One end of the limiting rod 39 passes through the square rod 32 and extends into the cylindrical disk 3. The limiting rods 39 are designed to assist in fixing the cylindrical tank, improving the stability of the cylindrical disk 3 during the wax oil dripping into the filling tank 4, thereby improving the low-temperature performance. The precision of the hot wax casting is achieved by welding a sloping block 34 to the other end of the limiting rod 39. A U-shaped rod 37 is slidably installed inside the hollow shell 1. Sloping blocks 35 are welded to both ends of the U-shaped rod 37, and the sloping blocks 34 and 35 are aligned horizontally. The sloping blocks 34 and 35 are in contact with each other, and both ends of the sloping blocks 34 and 35 are sloping, which facilitates the downward movement of the sloping blocks 35 to push the sloping blocks 34 to move, thereby pushing the limiting rod 39 to move. Two connecting rods 31 are symmetrically installed at the bottom of the moving plate 26, and the bottom ends of the two connecting rods 31 pass through the support frame 24 and are fixedly connected to the U-shaped rod 37. The vertical movement of the moving plate 26 drives the vertical movement of the U-shaped rod 37 through the connecting rods 31.

[0033] In this invention, it should be noted that annular heaters 30 are installed on the outside of the conveying hose 27, solenoid valve 28, and guide pipe 29. The design of the annular heaters 30 is to heat the conveying hose 27, solenoid valve 28, and guide pipe 29, preventing the wax oil from solidifying inside the conveying hose 27, solenoid valve 28, and guide pipe 29, thus affecting the flow and output of the wax oil. Two fixing rings are symmetrically welded inside the hollow shell 1, and a U-shaped rod 37 is slidably installed inside the fixing ring. The design of the fixing rings facilitates the sliding installation of the U-shaped rod 37. The cylindrical disk 3... Two or more limiting holes 33 are evenly machined at each end, and the number of limiting holes 33 is the same as the number of filling grooves 4. One end of the limiting rod 39 extends into the limiting hole 33. The limiting hole 33 facilitates the insertion of the limiting rod 39 into the cylindrical disk 3, thereby providing auxiliary fixation for the cylindrical disk 3. A second spring 36 is mounted on the annular side of the limiting rod 39, and the two ends of the second spring 36 are respectively welded to the inclined block 34 and the square rod 32. The design of the second spring 36 facilitates the movement and reset of the inclined block 34 and the limiting rod 39, thereby facilitating the adjustment of the cylindrical disk. Angle 3 allows for the recycling of the injection groove 4 on the cylindrical disk 3. The injection groove 4 has a cylindrical groove machined inside, and a T-shaped pusher 6 is slidably installed inside the cylindrical groove. An L-shaped rod 20 is welded to one end of the T-shaped pusher 6. Two or more square holes are evenly opened at one end of the cylindrical disk 3. One end of the L-shaped rod 20 passes through the square holes and extends to the outside of the cylindrical disk 3. The design of the L-shaped rod 20 facilitates the movement of the T-shaped pusher 6, thereby facilitating the pushing of the solidified low-temperature wax to the outside of the injection groove 4. A U-shaped strip 15 is slidably installed at one end of the hollow shell 1, and the U-shaped strip 15 contains... The cylindrical plate 3 has an arc-shaped groove, the center of which is on the same horizontal line as the center of the rotating plate. This facilitates the L-shaped rod 20 to enter the arc-shaped groove of the U-shaped bar 15 during the rotation of the cylindrical plate 3, thus facilitating the vertical pulling of the L-shaped rod 20. The hollow shell 1 has a groove inside, and a cylindrical rod 16 is welded inside the groove. A slider 17 is slidably installed on the cylindrical rod 16, and one end of the slider 17 is fixedly installed on the U-shaped bar 15. The design of the cylindrical rod 16 and the slider 17 facilitates the sliding installation of the U-shaped bar 15.

[0034] Specifically, a rotating shaft 7 is rotatably mounted inside the hollow shell 1, and the rotating shaft 7 is located below the U-shaped bar 15. A rope wheel 8 and a gear 9 are connected and mounted on the annular side of the rotating shaft 7 via a key. A pull rope 23 is mounted on the annular side of the rope wheel 8 via screws, and the other end of the pull rope 23 is mounted on the bottom end of the U-shaped bar 15 via screws. The rotation of the rope wheel 8 facilitates the winding of the pull rope 23, thereby facilitating the downward pulling of the U-shaped bar 15. An iron bar 19 is welded to one end of the hollow shell 1. A magnet 18 is mounted on the end of the rope wheel 8 near the hollow shell 1 via screws, and the magnet 18 is attracted and adhered to the iron bar 19. The attraction and adhesion of the magnet 18 and the iron bar 19 facilitates the fixation of the position of the rotating shaft 7, thereby fixing the position of the rope wheel 8 and the gear 9. A guide rod 13 is welded inside the hollow shell 1, and a push rod 12 is slidably mounted on the annular side of the guide rod 13. An electric motor is installed inside the hollow shell 1 via bolts. Push rod 14, with one end of electric push rod 14 fixedly connected to push rod 12. The design of electric push rod 14 facilitates horizontal movement. Electric push rod 14 is electrically connected to controller 38. A strip rod 11 is welded to one end of push rod 12. A rack 10 is installed at one end of the strip rod 11 by screws, and the rack 10 meshes with gear 9. The movement of rack 10 facilitates the rotation of gear 9, which in turn drives the rotating shaft 7 and rope wheel 8 to rotate. A square block 21 is installed inside the cylindrical groove by screws. A through groove is machined on the annular side of T-shaped push block 6, and square block 21 is slidably installed inside the through groove. The design of square block 21 and through groove facilitates the sliding installation of T-shaped push block 6. A spring 22 is welded to one end of square block 21, and the other end of spring 22 is welded to the inner wall of the through groove. The design of spring 22 facilitates the movement and reset of T-shaped push block 6.

[0035] The working principle of this embodiment is as follows: When wax oil needs to be poured into the injection tank 4, the electric push rod 14 is activated. The electric push rod 14 drives the moving plate 26 downward, which in turn drives the guide pipe 29 downward to approach the square frame 5 and the injection tank 4, thereby improving the pouring accuracy of the wax oil. The controller 38 controls the working time of the solenoid valve 28 to adjust the output of the wax oil, so as to accurately control the casting of low-temperature wax. When the guide pipe 29 moves downward to approach the square frame 5 and the injection tank 4, the controller 38 controls the electric push rod 14 to close, and at the same time activates the solenoid valve 28, thereby... Wax oil is poured into the injection tank 4. After the wax oil is poured, the controller 38 controls the solenoid valve 28 to close and simultaneously starts the electric push rod 14, which drives the moving plate 26 to move upward and pull the guide tube 29 to a farther position to avoid collision with the guide tube 29 during the rotation of the cylindrical disk 3. When the guide tube 29 moves to the appropriate position, the controller 38 controls the electric push rod 14 to close and simultaneously controls the stepper motor 2 to open. The stepper motor 2 drives the cylindrical disk 3 to rotate and move by an angle, thereby aligning the next injection tank 4 with the guide tube 29 vertically, thus facilitating uninterrupted low-temperature wax casting.

[0036] During the downward movement of the movable plate 26, the downward movement of the movable plate 26 drives the U-shaped rod 37 to move downward through the connecting rod 31. The downward movement of the U-shaped rod 37 drives the inclined block 35 to move downward. The inclined block 34 and the inclined block 35 are both inclined at one end. The downward movement of the inclined block 35 compresses the inclined block 34, causing the inclined block 34 to move horizontally. The horizontal movement of the inclined block 34 drives the limiting rod 39 to move and insert into the limiting hole 33, thereby helping to fix the position of the cylindrical disk 3. The horizontal movement of the inclined block 34 compresses the spring 36, causing the spring 36 to generate elastic force. When the movable plate 26 moves upward, the upward movement of the movable plate 26 drives the U-shaped frame to move. The movement of the U-shaped frame drives the inclined block 35 to move and separate from the inclined block 34. Under the action of the elastic force of the spring 36, the movement of the inclined block 34 drives the limiting rod 39 to move and disengage from the limiting hole 33, thereby facilitating the rotation of the cylindrical disk 3.

[0037] During the pouring process inside the injection trough 4 via the guide pipe 29, the controller 38 simultaneously controls the operation of the electric push rod 14. The operation of the electric push rod 14 drives the push rod 12 to move along the guide rod 13. The movement of the push rod 12 drives the rack 10 to move via the strip rod 11. The movement of the rack 10 drives the gear 9 to rotate. At the same time, the rotation of the gear 9 drives the rope wheel 8 to rotate via the rotating shaft 7. The rotation of the rope wheel 8 drives the magnetic block 18 to move and separate from the iron bar 19. The rotation of the rope wheel 8 winds up the pull rope 23, thereby pulling one end of the pull rope 23 downward. The pull rope 23 pulls the U-shaped bar 15 downward. The downward movement of the U-shaped bar 15 pulls the L-shaped rod 20 downward. The L-shaped rod 20 moves downward along the block 21 and stretches the spring 22, causing the spring 22 to generate elastic force. The downward movement of the L-shaped rod 20 pushes the T-shaped push block 6. The movement pushes the solidified low-temperature wax to the outside of the square frame 5. At this time, the magnetic block 18 rotates once and is attracted and adhered to the iron strip 19 again, thereby fixing the position of the rotating shaft 7, gear 9 and rope wheel 8. The rack 10 moves and separates from the gear 9. The attraction force between the magnetic block 18 and the iron strip 19 is greater than the elastic force of the spring 22, so the L-shaped rod 20 will not move upward to pull the rope wheel 8 to rotate. At the same time, the push rod 12 is in contact with the ejected low-temperature wax from the left and right. The push rod 12 continues to move to push the low-temperature wax, so that the low-temperature wax separates from the T-shaped push block 6, thereby facilitating the discharge of the low-temperature wax. During the subsequent movement of the push rod 12, the strip rod 11 passes under the gear 9 without pushing the gear 9 to rotate, thereby completing the discharge of the low-temperature wax. This makes it easy to add wax oil into the injection tank 4 again for casting processing, so that the casting work can be carried out continuously.

[0038] After the low-temperature wax is fed, the controller 38 controls the electric push rod 14 to work in the opposite direction to pull the push rod 12. The push rod 12 moves in the opposite direction and drives the rack 10 to move through the bar rod 11. The rack 10 moves and meshes with the gear 9. The push rod 12 continues to move and drives the rack 10 to move, which in turn drives the gear 9 to rotate in the opposite direction. The reverse rotation of the gear 9 drives the rope wheel 8 to rotate in the opposite direction through the rotating shaft 7, so that the magnetic block 18 moves and separates from the iron bar 19, which facilitates the reverse rotation of the gear 9 and the rope wheel 8. The reverse rotation of the rope wheel 8 causes the pull rope 23 to unfold. Under the action of the spring 22, the T-shaped push block 6 moves and resets, which drives the L-shaped rod 20 and the U-shaped bar 15 to move and reset in the opposite direction. At this time, the feeding tube 29 finishes adding wax oil into the filling tank 4. The stepper motor 2 rotates at a certain angle to facilitate pushing the next L-shaped rod 20 into the U-shaped bar 15, which in turn facilitates the ejection of the low-temperature wax from the next filling tank 4.
