Description

Technical Field

[0001] The present invention relates to the technical field of metal powder molding, and particularly to a metal powder molding machine for assisting in classification and recycling. Background Art

[0002] In the process of some metal powder molding and processing, adhesives are required to assist the metal powder in forming, so that the metal powder molding machine can complete the molding operation in a shorter time, improving production efficiency. When the metal powder molding machine is in use, waste materials will be generated due to overflow materials, flash materials, and unqualified products. In order to avoid waste, these waste materials need to be recycled, for example;

[0003] In the prior art, the patent with the publication number "CN116748519B" and the patent name "A Metal Powder Injection Molding Equipment" discloses that the external reflux circulation guiding system includes a cut-off drainage component for diverting and intercepting the liquid material in the outer centrifugal region layer, and a reflux drainage component for refluxing and circulating the intercepted liquid material. As the pushing rotating shaft rotates, the tiny air bubbles in the liquid material tend to be centrifugally distributed in the outer diameter direction. The cut-off drainage component diverts and intercepts the liquid material in the outer centrifugal region layer, and then the reflux drainage component continuously guides the intercepted liquid material back to the interval section at the right end of the pushing rotating shaft, so that the liquid material containing more air bubbles flows into the right side. Under the action of the negative pressure air pump, it is beneficial to make the air bubbles flow and be extruded to the right, thereby improving the density of the liquid material and further improving the injection molding quality. Another example is the patent with the publication number "CN117380961B" and the patent name "A Metal Powder Molding Machine with a Material Distribution and Recycling System" in the prior art. When injection molding a metal powder product, the waste generated by injection molding is put into the aggregate hopper. The aggregate hopper is weighed as a whole by a weighing sensor, and the weight data is fed back to the controller. When the total weight of the aggregate hopper reaches the set threshold, the controller controls the start of each component of the recycling system in the recycling area. The electric gate valves on the feeding hopper and the aggregate hopper are started to introduce the waste into the crushing cylinder. When feeding, the vibration motor is started to drive the aggregate hopper to vibrate to prevent the waste from clogging inside the aggregate hopper. After the waste enters the crushing cylinder, the two electric gate valves are closed again. The driving motor is started to drive the crushing shaft and the crushing blades to rotate to crush the waste. After crushing, the metering pump and the conveying solenoid valve are started. The metering pump introduces the solvent into the crushing cylinder along the conveying pipe to remove the binder on the crushed waste by the solvent. Then the sewage solenoid valve is started to discharge the solvent mixture in the crushing cylinder. Next, the electric heating blower and the two air guiding solenoid valves are started. The electric heating blower generates high-temperature air, which is introduced into the crushing cylinder along the intake manifold and discharged along the exhaust manifold. The crushed powder is dried by the high-temperature air. After drying, the discharge gate valve is started to introduce the waste into the grinding machine for grinding, and the metal powder generated after grinding is recycled at the outlet of the grinding machine.

[0004] When the metal powder molding machine in the above prior art recycles the waste of unqualified products, it is necessary to first use a detector to detect whether the products are qualified, and then the staff put the waste of unqualified products into the aggregate hopper. This will take a long time. Therefore, it cannot automatically detect and automatically put the waste of unqualified products into the aggregate hopper, which will affect the efficiency of waste crushing and classification recycling. So we propose a metal powder molding machine for auxiliary classification and recycling to solve the problems raised above. Summary of the Invention

Both the bearing plate 13 and the self-control blocks 131 are arc-shaped. The convex rod 10 is attached to the outer side of the self-control block 131, and the convex rod 10 forms a horizontal reciprocating sliding structure through the self-control block 131.

[0034] The crushing and recycling mechanism includes a crushing component 20 installed in the sorting and recycling chamber 6. An auxiliary lower crushing frame 19 is arranged outside the upper part of the crushing component 20. An auxiliary upper crushing frame 18 is fixed above the auxiliary lower crushing frame 19. Both the auxiliary upper crushing frame 18 and the auxiliary lower crushing frame 19 are installed in the sorting and recycling chamber 6, and the auxiliary upper crushing frame 18 and the auxiliary lower crushing frame 19 are arranged in a mirror image. Both the auxiliary upper crushing frame 18 and the auxiliary lower crushing frame 19 are arranged in a funnel shape. The crushing component 20 is arranged in a conical shape. A single-spiral reciprocating lead screw 24 is threadedly connected through the bottom inside of the crushing component 20. The lower end of the single-spiral reciprocating lead screw 24 is connected to the motor in the support frame 1 through a coupling. Limiting columns 21 are equidistantly installed on the outer side of the lower part of the crushing component 20.

The two discharge frames 15 are respectively arranged corresponding to the left sides of the sorting and filtering plate 16 and the guiding plate 17. A shielding plate 23 is arranged below the left side of the crushing component 20. The shielding plate 23 is installed in the sorting and recycling chamber 6. The shielding plate 23 is arranged in an inclined shape. The sorting and filtering plate 16 is arranged below the shielding plate 23.

[0035] First, inject the metal powder mixed with the adhesive into the feed hopper 2, and then transport the metal powder into the molding die in the molding chamber 4 through the spiral feeding mechanism 3. Then, the molding operation can be carried out. This part is the prior art, so no detailed introduction will be made here. After a period of time, open the molding die in the molding chamber 4. At this time, the molded product can automatically fall into a corresponding detection frame 9 directly below through the openings in the bottom surface of the molding chamber 4 and the upper surface of the support frame 1. At this time, through the fall of the molded product, a preliminary detection can be carried out on whether the molded product is qualified. Then, start the motor in the support frame 1 to drive the vertical rod 7 to rotate clockwise. When the vertical rod 7 rotates, it drives the four groups of detection frames 9 to rotate through the manual telescopic rod 14. At this time, the bottom plate 5 remains stationary. When the detection frame 9 behind the vertical rod 7 rotates to the right, the convex rod 10 behind the detection frame 9 will sequentially contact a plurality of arc-shaped self-control blocks 131. The self-control blocks 131 will exert a thrust on the convex rod 10 and the detection frame 9, causing the manual telescopic rod 14 corresponding to the detection frame 9 to contract, and the return spring 141 to store energy. By repeating such operations, the detection frame 9 can drive the molded product inside to perform a reciprocating horizontal shaking, so as to conduct a re-detection on whether the molded product is qualified. After the detection is completed, when the detection frame 9 on the right rotates to the front side, at this time, the staff can visually check whether the molded product in the detection frame 9 is cracked, or it can also be viewed through a camera. When the molded product in the detection frame 9 is not cracked, at this time, the staff can manually or use a manipulator to take out the molded product in the detection frame 9. When the molded product in the detection frame 9 is cracked, continue to rotate the detection frame 9 so that the detection frame 9 on the front side rotates to the left side of the vertical rod 7. At this time, the detection frame 9 on the left rotates to coincide with the through groove 51, and then the waste of the unqualified product in the detection frame 9 on the left falls into the classification and recycling chamber 6 through the through groove 51, the blanking frame 52 and the second feed port 62. Therefore, the waste of the unqualified product can be automatically assisted in recycling.

[0036] Subsequently, other waste materials can also enter the classification and recycling chamber 6 through the first feed inlet 61. Then, the waste materials of unqualified products and other waste materials fall into the space between the crushing lower auxiliary frame 19 and the crushing assembly 20 through the crushing upper auxiliary frame 18. The motor in the support frame 1 is started to drive the single-thread reciprocating lead screw 24 to rotate. When the single-thread reciprocating lead screw 24 rotates, it drives the crushing assembly 20 threadedly connected to the outer side above to perform reciprocating up and down movement. At this time, the limiting posts 21 on the outer side of the crushing assembly 20 slide in the chute 22, so as to ensure the stable reciprocating up and down movement of the crushing assembly 20. At this time, the crushing assembly 20 cooperates with the crushing lower auxiliary frame 19 to crush the waste materials of unqualified products and other waste materials. Part of the crushed waste materials directly fall onto the inclined classification and filtering plate 16 for filtering and classification, and the other part of the crushed waste materials are diverted by the inclined baffle plate 23 and fall onto the classification and filtering plate 16 for filtering and classification. Through the setting of the baffle plate 23, it can be avoided that the other part of the crushed waste materials fall onto the upper discharge frame 15. Then, the small particle waste materials after crushing fall onto the guide plate 17 through the classification and filtering plate 16 for collection, and the large particle waste materials after crushing remain on the classification and filtering plate 16 for collection. In the later stage, the corresponding discharge frame 15 can be opened to discharge and reuse the classified and recycled waste materials.

[0037] During the crushing process, the heating wire in the heating assembly 8 is used to heat up the classification and recycling chamber 6. When the decomposition or volatilization temperature of the adhesive is reached, it is maintained for a period of time. Then, through heating, the adhesive in the waste materials in the classification and recycling chamber 6 can be decomposed and volatilized, so as to remove the adhesive in the metal waste materials, forming non-toxic, harmless, and non-flammable and explosive gases or vapors. In the later stage, the connecting pipe 11 can also be connected to an external air extraction pump to collect the volatilized adhesive in the classification and recycling chamber 6. Since this part is prior art, it will not be described in detail here.

[0038] Embodiment 2: In the metal powder molding machine for auxiliary classification and recycling in this embodiment, part of the crushed waste materials can be sprinkled onto other positions on the classification and filtering plate 16 to avoid the accumulation of part of the crushed waste materials on the classification and filtering plate 16, which affects the filtering operation. The specific structure is referred to in the appendix Figures 8 - 10As shown, a rotating rod 25 is fixedly penetrated inside the upper part of the baffle plate 23. The rotating rod 25 is rotatably connected to the inside of the sorting and recycling chamber 6. A control rope 26 is wound and connected to the middle position of the rotating rod 25. A scroll spring 27 is nested and connected to the outer side of the front end of the rotating rod 25. One end of the scroll spring 27 is connected to the inside of the sorting and recycling chamber 6. The upper end of the control rope 26 penetrates the inner wall of the left side surface of the sorting and recycling chamber 6 and is connected to the left limiting post 21. On the basis of Embodiment 1, when the left limiting post 21 rises, at this time, the left limiting post 21 will pull one end of the control rope 26, and then the control rope 26 automatically drives the rotating rod 25 and the baffle plate 23 to rotate. At this time, the scroll spring 27 stores energy. When the left limiting post 21 descends, at this time, the stored energy of the scroll spring 27 can automatically drive the rotating rod 25 and the baffle plate 23 to rotate in the reverse direction and reset. Thus, the baffle plate 23 swings reciprocally, so that the baffle plate 23 can sprinkle some of the crushed waste falling on the baffle plate 23 to other positions on the sorting and filtering plate 16, avoiding the waste from accumulating at a fixed position on the sorting and filtering plate 16 and affecting the subsequent filtering operation.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
