Description

Technical Field

[0001] The present invention is applied to the background of lost foam casting, and its name is a lost foam casting device capable of automatic detection and its working method. Background Art

[0002] Lost foam casting is a new casting method in which paraffin or foam models similar in size and shape to the casting are bonded and combined into a model cluster.

In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0023] Please refer to Figure 1-6, the present invention provides a technical solution: a lost foam casting device capable of automatic detection and its working method, including a base 1, a first slide rail 2 is fixedly installed above the base 1, a motor 3 is arranged below the first slide rail 2, a controller 4 is slidably connected to the right side of the first slide rail 2, a commutating track 5 is connected to the controller 4 by bearings on the right side, a support plate 6 is slidably connected to the front side of the commutating track 5, a first cylinder 7 is fixedly installed on the front side of the support plate 6, a fixed plate 8 is arranged at the rod end of the first cylinder 7, a transfer furnace 9 is arranged on the front side of the fixed plate 8, a conversion pipe 10 is arranged at the bottom left side of the first cylinder 7, a first air chamber 11 is arranged at the bottom of the support plate 6, the bottom of the first air chamber 11 is connected to the conversion pipe 10, a first air pipe 12 is slidably connected inside the first air chamber 11, a second air chamber 13 is arranged on the front side of the support plate 6, a second air pipe 15 is slidably connected inside the second air chamber 13, a first spring 14 is welded to the bottom of the second air chamber 13, the other end of the first spring 14 is welded to the bottom of the second air pipe 15, an exhaust chamber 16 is arranged at the top of the second air chamber 13, an exhaust top 17 is slidably connected inside the exhaust chamber 16, a control board 18 is arranged above the support plate 6, a control block 19 is slidably connected to the right side of the control board 18, a first induction plate 20 is arranged on the right side of the control block 19. By the up and down sliding of the controller 4, the up and down displacement of the transfer furnace 9 is controlled and the rotation and inclination of the transfer furnace 9 are controlled. The position change of the transfer furnace 9 is controlled by the commutating track 5. Before pouring, a specified amount of molten water needs to be poured into the transfer furnace 9. Different specifications of castings require different amounts of molten water, so it is necessary to detect and limit the pouring amount. When pouring molten water into the transfer furnace 9, the weight of the transfer furnace 9 increases. At this time, the rod of the first cylinder 7 will be pressed down by the fixed plate 8. The gas inside the first cylinder 7 will be discharged from the conversion pipe 10 under the pressure. At this time, the gas in the first air chamber 11 will increase and push up the first air pipe 12. The second air chamber 13 is normally under the elastic force of the first spring 14, and the second air pipe 15 inside is at the lowest end. When the first air pipe 12 rises, it will push the second air pipe 15. At this time, the gas in the second air chamber 13 will be transferred from the second air chamber 13 to the exhaust chamber 16, so as to push out the exhaust top 17. The worker adjusts the position of the first induction plate 20 on the control board 18 according to the required specified amount. When the exhaust top 17 touches the first induction plate 20, it means that the weight of the molten water in the transfer furnace 9 has reached the standard. At this time, the injection of molten water will be stopped, achieving the effect of automatically detecting the weight of the transfer furnace 9 and preventing accidents, avoiding accidental situations such as errors in subsequent castings;

[0024] A first support frame 22 is provided on the front side of the support plate 6, a down-pressor 23 is provided inside the first support frame 22, a second cylinder 24 is provided at the output end of the down-pressor 23, a pressure plate 27 is provided at the gas rod end of the second cylinder 24, and a detection cover 21 is provided above the pressure plate 27. A limit plate 26 is provided on the outer side of the first support frame 22, and a second spring 25 is welded on the top of the limit plate 26. The top of the second spring 25 is welded to the second cylinder 24. When the injection into the transfer furnace 9 is completed and reaches the specified position, the detection cover 21 will rotate to be flush with the transfer furnace 9. Because there will be a subsequent inspection of the outlet, it is necessary to press down and seal the detection cover 21 and the transfer furnace 9 to prevent the smelting water from overflowing from other positions. After the detection cover 21 is closed, the down-pressor 23 drives the second cylinder 24 to fall to the specified position, so that the detection cover 21 contacts the transfer furnace 9, and then the second cylinder 24 starts to press the pressure plate 27 through the gas rod, so that the detection cover 21 and the transfer furnace 9 are tightly fitted;

[0025] A rotating plate 60 is provided at the opening of the detection cover 21, a piston 36 is provided on the outside of the detection cover 21, a rotating rod of the rotating plate 60 is connected to the internal cam of the piston 36, a contact piece 37 is provided at the output end of the piston 36, a buffer 39 is provided on the outside of the detection cover 21, and a second induction plate 38 is provided below the buffer 39. After the transfer furnace 9 reaches the specified position, it rotates and tilts to pour the internal smelting water into the pouring bin 49. At this time, in order to facilitate pouring, the smelting water will flow out of the outer outlet of the transfer furnace 9. In order to prevent the outlet from being blocked, a rotating plate 60 is provided through a special high-temperature resistant material. When the smelting water flows out, it will impact the rotating plate 6 0 to make it rotate. At this time, the rotating shaft of the rotating plate 60 will drive the internal cam of the right piston 36 to rotate, so that the piston 36 makes a piston movement. Each time the piston 36 slides outward, it will contact the second sensing plate 38 under the buffer 39 and then retract, indicating that the smelting water flows out normally. When the outlet is blocked, causing the smelting water to flow out slowly or completely blocked and unable to flow out, the rotating plate 60 will rotate slowly or stop rotating. At this time, the second sensing plate 38 will not be able to receive a signal within the specified time interval or will not be able to receive a signal at all. At this time, the pouring will be stopped and the staff will be notified to check, so as to achieve the detection effect of whether the outlet is blocked;

[0026] Above the base 1, there is a second slide rail 29. A support base 30 is slidably connected above the second slide rail 29. At the top of the support base 30, there is a second support frame 31. At the top of the second support frame 31, there is a third air cylinder 32. A connecting rod 33 is slidably connected to the fixed shaft at the air rod end of the third air cylinder 32. The inner side of the second support frame 31 is connected to a melting furnace 34 by bearings. The connecting rod 33 is connected to the rotating shaft of the melting furnace 34. On the support base 30, there is a fifth air cylinder 35. At the air rod end of the fifth air cylinder 35, there is a third support frame 40. Above the third support frame 40, there is a heater 42. At the bottom of the heater 42, there is a sealing cover 41. Raw materials are put into the melting furnace 34, and then the fifth air cylinder 35 is started to drive the third support frame 40 to drop. At this time, the sealing cover 41 contacts the melting furnace 34, and then the heater 42 is started to heat the raw materials through the internal heating elements and detect the internal temperature in real time;

[0027] Above the base 1, there is a detection frame 28. Above the base 1, there is a first heightening frame 43. Above the first heightening frame 43, there is a first robotic arm 44. Above the first robotic arm 44, there is a salvage hand 45. When the transfer furnace 9 slides to the right on the transposition track 5, the detection frame 28 detects the surface of the melting water in the transfer furnace 9. If impurities are detected floating on the top and need to be cleaned, the first robotic arm 44 controls the salvage hand 45 to carry out the salvage and cleaning;

[0028] Above the base 1, there is a second heightening frame 46. Above the second heightening frame 46, there is a third slide rail 47. A pouring bin 49 is slidably connected above the third slide rail 47. There is a rotating bottom 48 outside the pouring bin 49. Above the rotating bottom 48, there is a second robotic arm 50. Above the second robotic arm 50, there is a third robotic arm 51. At the end of the third robotic arm 51, there is a limiting ring 52. Above the limiting ring 52, there is a lighter 53. At the bottom of the lighter 53, there is a fuel injector 58. There is a pusher 57 outside the fuel injector 58. A push rod 56 is slidably connected inside the pusher 57. Above the limiting ring 52, there is a support ring 59. At the bottom of the support ring 59, there is a fourth air cylinder 54. At the air rod end of the fourth air cylinder 54, there is an elastic force sensor 55. Before pouring, the second robotic arm 50 and the third robotic arm 51 cooperate with each other to fit the limiting ring 52 above the casting hole in the casting sand, and then wait for pouring. At the same time, the fourth air cylinder 54 slowly presses down the air rod, thereby pushing the push rod 56, so that the fuel in the fuel injector 58 is ejected from the lighter 53 and ignited by the lighter 53, so as to ignite the smoke during pouring and protect the environment. When the melting water overflows, the melting water will block the lighter 53, so that the fuel in the fuel injector 58 cannot be ejected. At this time, the continuous advancement of the fourth air cylinder 54 will cause the elastic force sensor 55 to detect an increase in resistance, thereby stopping the continuous pouring.
