Description

Technical Field

[0001] The utility model belongs to the technical field of powder metallurgy injection molding process, and in particular relates to an automatic cleaning device for MIM products after degreasing. Background Art

[0002] Metal injection molding, referred to as MIM, is a process of selecting metal powder and binder that meet the requirements of MIM, and then using appropriate methods to mix the powder and binder into a uniform feed at a certain temperature. After granulation, the molded blank is injected and then degreased and sintered to become the final product. Degreasing is to place the injection-molded MIM molded blank on the product placement tray, and then send it into the degreasing furnace to remove the binder in the MIM molded blank by heating and decomposition. After the MIM molded blank is degreased in the degreasing furnace, there will be some debris on the surface of the MIM molded blank, which needs to be cleaned to improve the subsequent sintering quality of the MIM molded parts. At present, when cleaning the MIM products after degreasing, the debris on the surface of the MIM products is blown away by manual mouth blowing. Manual blowing of debris not only has uneven blowing force, easy to leak, and the debris is not blown clean, and the MIM product is blown down, but also the speed of manual blowing is slow, which seriously affects the production efficiency. Therefore, it is an objective need to develop an automatic cleaning device for MIM products after degreasing, which is easy to use, highly automated, clean and efficient in chip blowing. Summary of the invention

[0003] The utility model aims to provide an automatic cleaning device for MIM products after degreasing, which is easy to use, highly automated, clean and efficient in blowing off chips.

[0004] The purpose of the utility model is achieved in this way, including a working platform and a product placement plate, a horizontal mover is installed in the middle of the working platform, the product placement plate is movably placed on the working platform on both sides of the horizontal mover, and support frames extending to the top of the product placement plate are vertically installed on both sides of the horizontal mover, and a clean air pipe with closed ends is fixedly installed on the support frame, and a row of clean air nozzles are installed at equal intervals at the bottom of the clean air pipe along its length direction. A compressed air storage tank is installed above the working platform, and the compressed air storage tank is connected to the clean air pipe through an air inlet pipeline.

[0005] Compared with the traditional manual chip blowing method, the advantages of this device are: first, this device uses a translation drive to drive the cleaning air pipe to blow the chips of the MIM products on the product placement plate. When the cleaning air pipe is moving, the wind force sprayed by the cleaning air nozzle is relatively uniform. The mobile cleaning air nozzle is used to clean the debris on the surface of the MIM product, so that the debris on the surface of the MIM product can be thoroughly blown away, avoiding the phenomenon of MIM product leakage and debris not being blown away; second, this device uses a translation drive to drive the cleaning air pipes on both sides to clean the MIM products on two product placement plates at the same time, so that two product placement plates can be cleaned at one time, which can effectively improve the efficiency of the cleaning operation, and only needs to manually place the product placement plate on the work platform to automatically clean and blow away the debris on the surface of the MIM product. The degree of automation is high, and it has the advantages of being easy to use, saving time and effort, and is easy to promote and use. BRIEF DESCRIPTION OF THE DRAWINGS

Implementation

[0011] The present invention is further described below in conjunction with the accompanying drawings, but the present invention is not limited in any way. Any changes or improvements made based on the teachings of the present invention belong to the protection scope of the present invention.

[0012] like Figures 1 to 4As shown, the utility model includes a working platform 1 and a product placement plate 2. The product placement plate 2 is a device used in the prior art. A plurality of placement slots are arranged on the product placement plate 2. MIM products are placed in the placement slots. A horizontal mover is installed in the middle of the working platform 1. The product placement plate 2 is movably placed on the working platform 1 on both sides of the horizontal mover. Support frames 3 extending to the top of the product placement plate 2 are vertically installed on both sides of the horizontal mover. The translation driver can drive the support frame 3 to reciprocate along the direction of the product placement plate 2. A clean air pipe 4 with closed ends is fixedly installed on the support frame 3. A row of clean air nozzles 5 are evenly spaced at the bottom of the clean air pipe 4 along its length direction. The clean air nozzle 5 is a structure used in the prior art and is used to blow the compressed air in the compressed air storage tank 6 to the product placement plate. A compressed air storage tank 6 is installed above the working platform 1. The compressed air storage tank 6 is connected to the clean air pipe 4 through an air intake pipeline.

[0013] The method of using the device is as follows: the product placement tray 2 taken out from the degreasing furnace is directly transferred to the working platform 1, and the product placement tray 2 is placed on both sides of the translation mover, and then the air inlet pipeline connected to the clean air pipe 4 is opened, and the compressed air in the compressed air storage tank 6 enters the corresponding clean air pipe 4 through the air inlet pipeline. At this time, the translation driver drives the support frame 3 and the clean air pipe 4 to move back and forth above the product placement tray 2. During the movement of the support frame 3 and the clean air pipe 4, the compressed air is ejected through the clean air nozzle 5, and the ejected compressed air can clean and purge the debris on the surface of the MIM product. The device utilizes a translation driver to drive the cleaning air pipe 4 to blow away the debris of the MIM product on the product placement plate 2. During the movement of the cleaning air pipe 4, the wind force sprayed by the cleaning air nozzle 5 is relatively uniform. The debris on the surface of the MIM product is cleaned by the moving cleaning air nozzle 5, so that the debris on the surface of the MIM product can be completely blown away, thereby avoiding the phenomenon of MIM product leakage and debris not being blown away. At the same time, the device utilizes a translation driver to drive the cleaning air pipes 4 on both sides to clean the MIM products on two product placement plates 2 at the same time, so that two product placement plates 2 can be cleaned at one time, which can effectively improve the efficiency of the cleaning operation, and only needs to manually place the product placement plate 2 on the working platform 1, so that the debris on the surface of the MIM product can be automatically cleaned and blown away, with a high degree of automation, and has the advantages of being easy to use, saving time and effort.

[0014] Furthermore, in order to prevent the product placement tray 2 from moving or turning over during the cleaning and purging process, a stopper 7 for use with the product placement tray 2 is installed on the side of the work platform 1, and a slot is processed on one side surface of the stopper 7. The end of the product placement tray 2 is provided with an insertion rod matching the slot, and the insertion rod is movably inserted in the slot. When it is necessary to clean and purge the debris on the surface of the MIM product, the insertion rod at the end of the product placement tray 2 is inserted into the slot, so that the product placement tray 2 can be movably fixed on the work platform 1. After the debris on the surface of the MIM product is cleaned and purged, the product placement tray 2 is pulled, and the insertion rod at the end of the product placement tray 2 is pulled out of the slot. It is convenient and quick to use.

[0015] Furthermore, the horizontal mover is a translation cylinder, which has a high degree of automation. The translation cylinder is a structure used in the prior art and can be directly purchased as a finished product based on the stroke and pressure used. The cylinder seat of the translation cylinder is installed on the working platform 1, and the support frame 3 is installed on the end of the piston rod of the translation cylinder. The translation cylinder drives the support frame 3 to reciprocate. The translation cylinder runs smoothly and can ensure that the support frame 3 reciprocates above the product placement plate 2.

[0016] In addition to using a translation cylinder, the horizontal mover can also use a screw translation mechanism. The horizontal mover includes a drive motor 8, a transmission screw 9 and a fixed base 10. The drive motor 8 is a structure used in the prior art. The finished product can be directly purchased according to the power used. The fixed base 10 is fixedly installed on the work platform 1. A screw groove is processed on the fixed base 10. The transmission screw 9 is rotatably installed in the screw groove. The drive motor 8 is installed on the outside of one end of the fixed base 10. The output shaft of the drive motor 8 is transmission-connected to one end of the transmission screw 9. A slide seat 11 is slidably installed on the transmission screw 9. The support frame 3 is installed on the slide seat 11. When in use, the drive motor The machine 8 drives the transmission screw 9 to rotate. During the rotation of the transmission screw 9, the slide 11 can drive the support frame 3 to move along the transmission screw 9. In order to ensure that the slide 11 can move smoothly along the transmission screw 9, two slide grooves 12 are symmetrically processed on the fixed base 10 on both sides of the transmission screw 9. The two slide grooves 12 are arranged parallel to the transmission screw 9. A slider 13 matching the slide groove 12 is arranged at the bottom of the slide 11. The slider 13 is slidably installed in the corresponding slide groove 12. The slider 13 and the slide 11 are an integrally connected structure. During the movement of the slide 11, the slider 13 can move along the slide groove 12, so that the slide 11 can remain stable during the movement of the transmission screw 9.

[0017] Furthermore, the air inlet pipeline includes an air outlet pipe 14, a buffer air bag 15 and a fixed pipe 16. The air outlet pipe 14 is connected to the air outlet of the compressed air storage tank 6. A pressure gauge and a control valve are installed on the air outlet pipe 14. The buffer air bag 15 is installed at the end of the air outlet pipe 14. The buffer air bag 15 is used to store the compressed air discharged from the compressed air storage tank 6. The buffer air bag 15 can adjust the pressure of the compressed air to stabilize the pressure of the compressed air entering the clean air pipe 4, ensuring that the compressed air ejected from the clean air nozzle 5 has uniform wind force. The fixed pipe 16 is an L-shaped structure, and one end of the fixed pipe 16 is connected to the clean air pipe 4 A quick connector 17 is installed at the other end of the fixed pipe 16, and an air intake hose 18 is provided on the buffer air bag 15. An air intake valve is provided on the air intake hose 18. The air intake hose 18 is movably connected to the quick connector 17. When in use, the control valve on the air outlet pipe 14 is opened, and the compressed air in the compressed air storage tank 6 first enters the buffer air bag 15. After the pressure is adjusted by the buffer air bag 15, the air intake valve on the air intake hose 18 is opened, and the compressed air enters the clean air pipe 4 through the air intake hose 18 and the fixed pipe 16, and then is sprayed out through each clean air nozzle 5, so as to clean and purge the debris on the surface of the MIM product.

[0018] Furthermore, in order to increase the cleaning and blowing range of the cleaning air pipe 4, two rows of auxiliary air nozzles 19 are arranged at equal intervals on both sides of the cleaning air nozzle 5 along the length direction of the cleaning air pipe 4. The auxiliary air nozzle 19 has the same structure as the cleaning air nozzle 5. The auxiliary air nozzle 19 and the cleaning air nozzle 5 are staggered at the bottom of the cleaning air pipe 4. The auxiliary air nozzle 19 and the cleaning air nozzle 5 clean and blow the surface of the MIM product at the same time, which has a larger cleaning range and can effectively improve the effect of cleaning and blowing debris on the surface of the MIM product.
