Technical Field

[0001] This invention relates to the field of MIM part processing technology, specifically an automatic loading and unloading device for MIM part processing and shaping, and its usage method. Background Technology

[0002] MIM parts are widely used in the manufacturing industry, mainly by injection molding a plasticized mixture of metal powder and binder.

[0003] When manufacturing MIM parts, workers need to place multiple sets of molded parts inside the product loading machine, and use the handling mechanism and stamping device to shape the molded parts, and then use the unloading device to unload them.

[0004] Through long-term observation, it was found that some of the cylinders on the conveying mechanism accumulate a lot of impurities after prolonged use, causing the conveying mechanism to experience greater resistance during movement. Regularly applying lubricating oil to the slide rods of the conveying mechanism is too cumbersome and affects the part forming progress. Therefore, to address the above problems, an automatic loading and unloading device for MIM part processing and forming and its usage method are proposed. Summary of the Invention

[0007] Preferably, the top of the second top block is fixedly connected to a housing; a sliding rod is fixedly connected to the inner side wall of the top of the collection box; a sliding plate is fixedly connected to the end of the sliding rod; the sliding plate is slidably configured in the middle of the housing; two sets of liquid outlet grooves are opened in the middle of the sliding plate; a rotating plate is connected to the end of the liquid outlet groove by a torsion spring; this reduces the phenomenon of large resistance and jamming when the slider slides.

[0008] Preferably, a valve is fixed to the inner wall of the outlet; a connector is fixed to the middle of the valve; a first elastic rope is fixed to the bottom of the connector; the other end of the first elastic rope is fixed to the bottom of the collection box; this reduces the phenomenon that some external impurities transfer into the collection box through the large aperture of the outlet when the outlet is not in use, thus reducing the troublesome problem for staff during cleaning.

[0009] Preferably, two sets of second elastic ropes are fixed to the inner sidewall of the collection box; a water guide plate is fixed to the end of the second elastic rope; the end of the water guide plate is arc-shaped; a rotating shaft is rotatably connected inside the collection box; a pull rope is fixed to the end of the water guide plate; the other end of the pull rope is fixed to the end of the second top block; the pull rope is slidable at the bottom of the rotating shaft; this reduces the phenomenon of some lubricating oil accumulating at the edge of the inside of the collection box for a long time, making it difficult to transfer to the outside.

[0010] Preferably, the inner wall of the collection box is provided with two sets of sliding grooves; two sets of limiting blocks are fixed to the end of the water guide plate; the limiting blocks are slidably set in the middle of the sliding groove; this can reduce the phenomenon of the water guide plate shifting after long-term use, thus preventing the problem of jamming when the pull rope pulls the water guide plate.

[0011] Preferably, a telescopic rod is fixedly connected to the top of the second top block; the top of the telescopic rod is fixedly connected to the inner side wall of the top of the collection box; the telescopic rod is set in the middle of the spring; this can reduce the spring from becoming too elastic and bending after long-term use, and improve the stability of the spring during operation.

[0012] Preferably, a gasket is fixed to the end of the second top block; the end of the pull rope is located in the middle of the gasket; this can reduce the phenomenon of the end of the pull rope breaking due to prolonged bending.

[0013] A method of using an automatic loading and unloading device for machining and shaping MIM parts, applicable to any of the above-mentioned automatic loading and unloading devices for machining and shaping MIM parts, the method comprising the following steps:

[0014] S1: After removing the molded parts from the mold, weigh the multiple molded parts using a weighing tool, and divide the weighed molded parts into equal portions for later use.

[0015] S2: Place the multiple shaped parts into the feeding device in sequence, turn on the feeding device switch to transfer the shaped parts to the end of the cylinder body in sequence, and transfer the parts to the processing body with the help of the feeding and conveying device.

[0016] S3: When the slider in the middle of the cylinder body slides, it will cause the first top block to contact the second top block and squeeze out the lubricating oil inside the collection box until it falls on the middle of the cylinder body. The sliding slider will evenly apply the lubricating oil to the middle of the cylinder body, and at the same time, it will work with the worktable to shape the parts.

[0017] The advantages of this invention are:

[0018] 1. The automatic loading and unloading device and its usage method for machining and shaping MIM parts as described in this invention, by setting a collection box at the end of the cylinder body, can apply lubricating oil to a part of the cylinder body, and use a sliding slider to apply it to the middle of the cylinder body. This can reduce the problem of excessive impurities or rust adhering to the middle of the cylinder body after long-term use, which would cause greater resistance when the slider slides in the middle of the cylinder body, and improve the stability of the cylinder body and slider during operation.

[0019] 2. The automatic loading and unloading device and its usage method for processing and shaping MIM parts according to the present invention, by providing a housing on the top of the second top block, increases the time that the liquid outlet end leaks into the collection box, thereby increasing the contact area between the lubricating oil inside the collection box and the middle part of the cylinder body, improving the stability of the slider in the middle part of the cylinder body when sliding, and reducing the phenomenon of large resistance and jamming when the slider slides.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 2-4As shown, the system includes a workbench 1; a feeding assembly 11 is installed at one end of the workbench 1; a cylinder body 12 is installed in the middle of the workbench 1; a slider 13 is slidably connected to the middle of the cylinder body 12; a first top block 14 is fixed to the top of the slider 13; the middle of the first top block 14 is arc-shaped; a collection box 15 is fixed to the end of the cylinder body 12; multiple sets of springs 16 are fixed to the inner side wall of the top of the collection box 15; a second top block 17 is fixed to the bottom of the multiple sets of springs 16; the bottom of the second top block 17 is arc-shaped; multiple sets of liquid outlets 18 are opened in the middle of the second top block 17. During operation, the operator needs to install the workbench 1 on the ground, and then inject an appropriate amount of molded parts into the workbench 1. After the feeding assembly 11 works, the parts are transferred one by one to the position of the cylinder body 12. At this time, the cylinder body 12 is turned on to transport the parts and process them. Because the collection box 15 is set at the end of the cylinder body 12, the operator needs to pre-fill the collection box 15. An appropriate amount of lubricating oil is injected internally, causing the slider 13 to gradually approach the collection box 15 as it slides in the middle of the cylinder body 12, until the first top block 14 and the second top block 17 come into contact. The curved surfaces of these two blocks push the second top block 17 into the collection box 15. At this time, the lubricating oil inside the collection box 15 flows along the outlet 18 in the middle of the second top block 17 onto the middle of the cylinder body 12. When the slider 13 grips a part, the first top block 14 and the second top block 17 move away from each other, aided by the spring 1. The reaction force generated after the 6th is squeezed will reset the second top block 17. This step can apply lubricating oil to part of the cylinder body 12 and apply it to the middle of the cylinder body 12 with the help of the sliding slider 13. This can reduce the problem of more impurities or rust adhering to the middle of the cylinder body 12 after long-term use, which would cause greater resistance when the slider 13 slides in the middle of the cylinder body 12, thus improving the stability of the cylinder body 12 and the slider 13 during operation.

[0030] like Figure 4 and 5As shown, a housing 2 is fixedly connected to the top of the second top block 17; a sliding rod 21 is fixedly connected to the inner side wall of the top of the collection box 15; a sliding plate 22 is fixedly connected to the end of the sliding rod 21; the sliding plate 22 is slidably disposed in the middle of the housing 2; two sets of liquid outlet grooves 23 are opened in the middle of the sliding plate 22; a rotating plate 24 is connected to the end of the liquid outlet groove 23 by a torsion spring; during operation, by setting the housing 2 on the top of the second top block 17 and injecting an appropriate amount of liquid into the housing 2 in advance, when the second top block 17 moves upward, the liquid at the bottom of the sliding plate 22 will be squeezed to the top of the sliding plate 22 after the sliding plate 22 moves, and the rotating plate 24 will... 4 will be pushed open by the water flow, thereby accelerating the liquid flow speed. At the same time, the slide plate 22 will gradually move downward after being subjected to the reaction force of the spring 16. Combined with the torsional force of the rotating plate 24 and the force of the water flow, the rotating plate 24 and the liquid outlet 23 will be closed, and the reset speed of the second top block 17 will be reduced. This step increases the time that the end of the liquid outlet 18 leaks into the collection box 15, thereby increasing the contact area between the lubricating oil inside the collection box 15 and the middle part of the cylinder body 12, improving the stability of the slider 13 in the middle of the cylinder body 12 when sliding, and reducing the phenomenon of large resistance and jamming when the slider 13 slides.

[0031] like Figure 4 and 6 As shown, a valve 3 is fixedly connected to the inner wall of the outlet 18; a connector 31 is fixedly connected to the middle of the valve 3; a first elastic rope 32 is fixedly connected to the bottom of the connector 31; the other end of the first elastic rope 32 is fixedly connected to the bottom of the collection box 15. During operation, by setting the valve 3 in the middle of the outlet 18, when the second top block 17 moves upward, the first elastic rope 32 will pull the valve 3, causing the middle of the valve 3 to open, thereby transferring some of the lubricating oil inside the collection box 15 to the middle of the cylinder body 12. At the same time, after the second top block 17 is reset, the valve 3 will close with the outlet 18. This step can improve the flexibility of the outlet 18 during operation and reduce the phenomenon that some external impurities are transferred into the collection box 15 through the large aperture of the outlet 18 when the outlet 18 is not in use, which would cause trouble for the staff during cleaning.

[0032] like Figure 4As shown, two sets of second elastic ropes 4 are fixed to the inner wall of the collection box 15; a water guide plate 41 is fixed to the end of the second elastic rope 4; the end of the water guide plate 41 is arc-shaped; a rotating shaft 42 is rotatably connected inside the collection box 15; a pull rope 43 is fixed to the end of the water guide plate 41; the other end of the pull rope 43 is fixed to the end of the second top block 17; the pull rope 43 is slidably set at the bottom of the rotating shaft 42; during operation, by setting the water guide plate 41 inside the collection box 15, when the second top block 17 moves in the middle of the collection box 15, it will pull the pull rope 43 and drive the water guide plate 41 to move in the middle of the collection box 15, while pushing the lubricant at the edge of the collection box 15 to the position of the second top block 17. With the help of the second elastic rope 4, the water guide plate 41 can be pulled back to its original position. This process is repeated. This step can increase the flow speed of the lubricating oil inside the collection box 15 and reduce the phenomenon that some lubricating oil accumulates at the edge of the collection box 15 for a long time, making it difficult to transfer to the outside.

[0033] like Figure 4 As shown, the inner wall of the collection box 15 is provided with two sets of sliding grooves 5; two sets of limiting blocks 51 are fixed to the end of the water guide plate 41; the limiting blocks 51 are slidably set in the middle of the sliding grooves 5; during operation, by setting the limiting blocks 51 at the end of the water guide plate 41, when the water guide plate 41 slides inside the collection box 15, the limiting blocks 51 will limit the position of the water guide plate 41. This step can reduce the phenomenon of the water guide plate 41 shifting after long-term use, so as to prevent the problem of the pull rope 43 pulling the water guide plate 41 from getting stuck.

[0034] like Figure 4 As shown, a telescopic rod 6 is fixedly connected to the top of the second top block 17; the top of the telescopic rod 6 is fixedly connected to the inner side wall of the top of the collection box 15; the telescopic rod 6 is set in the middle of the spring 16; during operation, by setting the telescopic rod 6 in the middle of the second top block 17, the telescopic rod 6 will limit the movement position of the spring 16. This step can reduce the spring 16 from becoming too elastic and bending after long-term use, and improve the stability of the spring 16 during operation.

[0035] like Figure 4 As shown, a gasket 7 is fixed to the end of the second top block 17; the end of the pull rope 43 is located in the middle of the gasket 7; during operation, by providing a gasket 7 at the end of the second top block 17, the gasket 7 protects the end of the pull rope 43. This step can reduce the phenomenon of the end of the pull rope 43 breaking due to prolonged bending.

[0036] Please see Figure 4As shown in the embodiment of the present invention, a baffle 8 is provided on the top of the collection box 15; the baffle 8 is fixedly connected to the collection box 15; during operation, by providing the baffle 8 on the top of the collection box 15, the baffle 8 can block some external impurities, which can improve the cleanliness of the lubricating oil inside the collection box 15 and improve the stability of the lubricating oil during operation.

[0037] A method of using an automatic loading and unloading device for machining and shaping MIM parts, applicable to any of the above-mentioned automatic loading and unloading devices for machining and shaping MIM parts, the method comprising the following steps:

[0038] S1: After removing the molded parts from the mold, weigh the multiple molded parts using a weighing tool, and divide the weighed molded parts into equal portions for later use.

[0039] S2: Place the multiple shaped parts into the feeding device (11) in sequence, turn on the feeding device (11) switch to transfer the shaped parts to the end of the cylinder body (12) in sequence, and transfer the parts to the processing body with the help of the feeding and conveying device;

[0040] S3: When the slider (13) in the middle of the cylinder body (12) slides, the first top block (14) and the second top block (17) will come into contact, and the lubricating oil inside the collection box (15) will be squeezed out until it falls on the middle of the cylinder body (12). The sliding slider (13) will evenly apply the lubricating oil to the middle of the cylinder body (12), and at the same time, the worktable (1) will be used to shape the parts.

[0041] The working principle is as follows: Workbench 1 is installed on the ground, and a suitable amount of molded parts are injected into it. After the feeding assembly 11 operates, the parts are transferred one by one to the cylinder body 12. At this time, the cylinder body 12 is switched on to move the parts and facilitate their processing. A collection box 15 is provided at the end of the cylinder body 12. The operator needs to inject a suitable amount of lubricating oil into the collection box 15 beforehand. This causes the slider 13 to gradually approach the collection box 15 as it slides in the middle of the cylinder body 12, until the first top block 14 contacts the second top block 17. The curved surfaces of the two blocks then push the second top block 17 into the collection box 15. At this time, the lubricating oil inside the collection box 15 will flow along the liquid outlet 18 in the middle of the second top block 17 to the middle of the cylinder body 12. When the slider 13 grabs the part, the first top block 14 and the second top block 17 will move away from each other. With the reaction force generated by the spring 16 being squeezed, the second top block 17 will be reset. By setting a housing 2 on the top of the second top block 17 and injecting an appropriate amount of liquid into the housing 2 in advance, when the second top block 17 moves upward, the liquid at the bottom of the slide plate 22 will be squeezed to the top of the slide plate 22 after the slide plate 22 moves. The rotating plate 24 will be pushed open by the water flow, thereby accelerating the liquid flow speed. At the same time, the slide plate 22 is subjected to the force of the spring 16. After the reaction force, it will gradually move downwards. Combined with the torsional force of the rotating plate 24 and the force of the water flow, it will close the rotating plate 24 with the outlet tank 23 and reduce the reset speed of the second top block 17. Because a valve 3 is provided in the middle of the outlet 18, when the second top block 17 moves upwards, the first elastic rope 32 will pull the valve 3, causing the middle of the valve 3 to open. This will transfer some of the lubricating oil inside the collection box 15 to the middle of the cylinder body 12. Simultaneously, after the second top block 17 resets, the valve 3 will close with the outlet 18. Because a water guide plate 41 is provided inside the collection box 15, the second top block 17 moves in the middle of the collection box 15. When in motion, the pull rope 43 is pulled, causing the water guide plate 41 to move in the middle of the collection box 15. At the same time, the lubricant at the edge of the collection box 15 is pushed to the position of the second top block 17. With the help of the second elastic rope 4, the water guide plate 41 can be pulled back to its original position. This process is repeated. By setting a limit block 51 at the end of the water guide plate 41, the limit block 51 will limit the position of the water guide plate 41 when it slides inside the collection box 15. By setting a telescopic rod 6 in the middle of the second top block 17, the telescopic rod 6 will limit the movement position of the spring 16. By setting a gasket 7 at the end of the second top block 17, the gasket 7 will protect the end of the pull rope 43.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
