It consists of a chain drive system, including a chain, sprockets, motor, and feeder. It is equipped with a material receiving cavity, inlet, support frame, and guide rail to ensure stable operation of the chain feeder. The hopper connects to the subsequent molding equipment and control system to control the chain speed, start and stop, etc. The chain drives the feeder to deliver the material to the hopper, achieving stable material conveying.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a powder injection molding metal parts feeding device, including a base 1, which serves to stably support the various components of the device. A housing 2 is fixedly connected to the top of the base 1, providing a closed processing environment for the metal powder injection molding process. A sliding plate 7 is slidably connected to the top of the base 1, which, through cooperation with a connecting rod 6, adjusts the position of the mold 8 and connects it to the injection tube 4 for processing. Two support frames 9 are fixedly connected to the outside of the base 1, providing mounting support for components such as a motor 11. A fixing plate 10 is fixedly connected to the outside of one of the support frames 9, providing a stable mounting surface for the motor 11. The motor 11 is fixedly connected inside the fixing plate 10, serving as the power source for the feeding system. A rotating rod 12 is fixedly connected to the drive end of the motor 11, transmitting power. Two sprockets 13 are fixedly connected to the outside of the rotating rod 12, connecting to the chain... The chain 14 forms a transmission mechanism. Both sprockets 13 are fitted with chains 14 on their outer sides. The chains 14 move under the drive of the sprockets 13, which in turn move the connecting plate 15 and then the feeding box 17 through the rotating shaft 16. The connecting plate 15 is fixedly connected to the outside of the chain 14. The movement of the chain 14 is transmitted to the rotating shaft 16, which in turn moves the feeding box 17. The rotating shaft 16 is fixedly connected inside the connecting plate 15. The baffle 18 touches the top of the hopper 3 slot. The feeding box 17 can tilt around the rotating shaft 16. The feeding box 17 is rotatably connected to the outside of the rotating shaft 16. It is a container for loading metal powder. The baffle 18 is fixedly connected to the outside of the feeding box 17 to control the tilting action of the feeding box 17. The discharge pipe 19 is fixedly connected inside the feeding box 17. When the feeding box 17 tilts, the metal powder inside flows into the hopper 3 through the discharge pipe 19. The sliding plate 7 has an ejection assembly for automatically demolding the processed parts inside.

[0034] Reference Figure 1 , Figure 4 and Figure 5 The ejection assembly includes a second motor 20, the top of which is fixedly connected to the inside of the sliding plate 7 and serves as the power source for the ejection assembly. A rotating plate 21 is fixedly connected to the drive end of the second motor 20, transmitting the rotational motion of the second motor 20 to the rotating column 22. The rotating column 22 is rotatably connected to the outside of the rotating plate 21, serving to transmit and convert motion. A connecting frame 23 is rotatably connected to the outside of the rotating column 22, swinging under the drive of the rotating column 22 and transmitting the swinging motion to the push rod 26. A connecting column 24 is rotatably connected to the outside of the connecting frame 23, serving to transmit motion. A connecting block 25 is rotatably connected to the outside of the connecting column 24, moving under the drive of the connecting frame 23, thereby causing the push rod 26 to move linearly under the limitation of the fixed block 27.

[0035] Reference Figure 1 , Figure 2 and Figure 4 The top of the housing 2 is fixedly connected to a hopper 3, which is the primary channel for metal powder to enter the housing 2. Inside the housing 2 is a fixedly connected injection molding tube 4, the core component for powder injection molding. The top of the base 1 is fixedly connected to two support plates 5, providing auxiliary support and guidance. Multiple connecting rods 6 are fixedly connected inside each support plate 5, allowing the sliding plate 7 to slide smoothly along a predetermined direction, ensuring the mold 8 can accurately reach its position during processing. The outside of the sliding plate 7 is fixedly connected to the mold 8, a key tool for metal part molding. The inside of the sliding plate 7 is slidably connected to the outside of multiple connecting rods 6, providing guidance and support for the movement of the sliding plate 7. The outside of the discharge pipe 19 contacts the inside of the hopper 3 under the movement of the chain 14. The chain 14 drives the feeding box 17 and the discharge pipe 19 to move. When the baffle 18 touches the top of the hopper 3 slot, it tilts the feeding box 17 and the discharge pipe 19, allowing the metal powder to flow from the discharge pipe 19 into the hopper 3. The outside of the baffle 18 contacts the inside of the hopper 3 under the movement of the chain 14. When the baffle 18 touches the top of the hopper 3 slot, it tilts the feeding box 17. The inside of the connecting block 25 is fixedly connected to the push rod 26, which is used to push the part out of the mold 8 to complete the automatic demolding operation. The outside of the push rod 26 is slidably connected to the fixing block 27 to ensure that the push rod 26 moves in a straight line during the movement. The bottom of the fixing block 27 is fixedly connected to the inside of the sliding plate 7 to provide guidance for the push rod 26. The bottom of the connecting frame 23 is slidably connected to the inside of the sliding plate 7. The connecting column 24 drives the connecting block 25 to move the push rod 26 and push the processed part out of the mold 8.

[0036] Working principle: When feeding is required, the motor 11 drives the rotating rod 12 to rotate, which in turn drives the sprockets 13 at both ends to rotate synchronously, thereby moving the chain 14 and driving the connecting plate 15 to move. At the same time, the rotating shaft 16 drives the feeding box 17 to move together. When it rises to a certain position, the baffle 18 touches the top of the hopper 3 slot, and the feeding box 17 will tilt around the rotating shaft 16. As a result, the metal powder inside will flow into the hopper 3 through the discharge pipe 19 and then into the box 2, thus achieving the effect of automatic feeding. It can accurately inject metal powder into the hopper 3, reduce the direct contact between the operator and the metal powder, improve production safety, and ensure the stability of the ratio of injection molding raw materials for each batch.

[0037] After the parts are processed, the motor 20 is started, which drives the rotating plate 21 to rotate, which in turn drives the rotating column 22 to rotate. When the rotating column 22 rotates with the rotating plate 21, it drives the connecting frame 23 to swing. The connecting frame 23 is then connected to the connecting block 25 through the connecting column 24, and swings back and forth, which drives the push rod 26 to move. The rotational motion is converted into linear motion by the limiting of the fixed block 27, so that the formed parts are pushed out of the mold 8, thereby achieving the effect of automatic demolding, shortening the processing cycle, improving the automation level of the equipment, reducing labor costs, and significantly improving production efficiency and stability.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
