[0028] This utility model embodiment provides a gear forming mold, including a housing 1, exemplarily, such as... Figure 1 , Figure 2 and Figure 3As shown, a door 2 is installed on one side wall of the box body 1, and an observation window 3 is embedded in one side wall of the door 2. A first handle 4 is installed at the edge of one side wall of the door 2. A fixing frame 5 is installed on the top of the box body 1, and several sets of cylinders 6 are installed at equal intervals at the bottom of the fixing frame 5. The output end of each set of cylinders 6 passes through the top of the box body 1 and is connected to a pressing mold 7. An installation platform 8 is installed on the bottom inner wall of the box body 1. A first slot 9 is opened at the bottom of the side wall of the box body 1 near the door 2. A collection box 10 is slidably attached to the bottom inner wall of the box body 1. The top of the collection box 10 is an open structure. The collection box 10 has a movable groove 11. A pull-out box 12 is slidably attached to the bottom inner wall of the collection box 10. One end of the pull-out box 12 passes through the movable groove 11 and is symmetrically equipped with two sets of second handles 13. Two sets of screens 14 are symmetrically arranged inside the collection box 10. The mesh size of the two sets of screens 14 is different. A discharge groove 15 is opened on one side wall of the collection box 10. Two sets of fixing blocks 16 are symmetrically installed on the side wall of the collection box 10 near the first empty groove 9. Two sets of limiting posts 17 are symmetrically installed on the side wall of the box body 1 near the box door 2. A set of limiting plates 18 is movably sleeved on each set of limiting posts 17. One side wall of each set of limiting plates 18 is attached to the top of one set of fixing blocks 16.

[0029] For example, such as Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, the top of the mounting platform 8, near the collection box 10, has several forming grooves 19 spaced at equal intervals. Each forming groove 19 contains a set of first electric push rods 20, and each set of first electric push rods 20 has a push plate 21 installed on its output end. A second empty groove 22 is formed on the side wall of the box body 1 away from the door 2. An installation groove 23 is formed on the inner wall of the box body 1 away from the door 2, located below the second empty groove 22. Several sets of second electric push rods 24 are spaced at equal intervals within the installation groove 23. A connecting plate 25 is slidably attached to the top of the mounting platform 8, away from the collection box 10. The output end of each set of second electric push rods 24 is installed on one side wall of the connecting plate 25. Several sets of second electric push rods 24 are spaced at equal intervals on the side wall of the connecting plate 25 near the collection box 10. Each metal powder box 26 has a storage cavity 27 at its top and a cavity 28 at its bottom. A conveying pipe 29 connects to the bottom of each metal powder box 26. Each conveying pipe 29 is equipped with an electric valve 30 and an electronic flow meter 31, both located directly below the electric valves 30. Each electric valve 30 and electronic flow meter 31 are located within one of the cavities 28. A movable plate 32 is located at the end of each metal powder box 26 furthest from the connecting plate 25. Two sets of telescopic rods 33 are symmetrically connected between each movable plate 32 and the metal powder box 26. Each set of telescopic rods 33 is equipped with a spring 34.

[0030] Working principle: Metal powder is added to storage chamber 27 through second empty slot 22. The second electric push rod 24 is activated, which moves the connecting plate 25 and moves the metal powder box 26 to directly above the forming tank 19. The electric valve 30 and electronic flow meter 31 are activated, and the metal powder in storage chamber 27 is transported to forming tank 19 through conveying pipe 29. Electronic flow meter 31 measures the amount conveyed. When the set amount is reached, the information is sent to electric valve 30, electric valve 30 closes, and transport stops. The second electric push rod 24 drives metal powder box 26 to return to its original position, ensuring the consistency of product quality.

[0031] Cylinder 6 drives the mold 7 to descend into the forming groove 19, thus forming the gear. The first electric push rod 20 is activated to drive the push plate 21 to rise to be level with the top of the mounting platform 8. The second electric push rod 24 drives the connecting plate 25 to move, while simultaneously moving the metal powder box 26. The metal powder box 26 drives the moving plate 32 to move. The moving plate 32 pushes the formed gear into the collection box 10, where it falls onto the top of the screen 14. After the first electric push rod 20 drives the push plate 21 to descend, it again delivers metal powder into the forming groove 19.

[0032] After the gear falls onto the screen 14, the residual metal powder on the gear passes through two sets of screens 14 and falls into the pull-out box 12 for collection. After proper treatment, it may be reused, which improves material utilization and reduces waste.

[0033] Pulling the second handle 13 will pull the pull-out box 12 out of the collection box 10, allowing for cleaning or replacement of the collected powder. Pulling the first handle 4 will open the box door 2, allowing the gears inside the collection box 10 to be removed.

[0034] When the second electric push rod 24 is activated, it moves the connecting plate 25 and moves the metal powder box 26 to directly above the forming tank 19. The electric valve 30 and the electronic flow meter 31 are activated, and the metal powder in the storage chamber 27 is transported to the forming tank 19 through the conveying pipe 29. Since there are multiple independent metal powder boxes 26, multiple gears can be produced at the same time. It can process metal powders of different materials or specifications at the same time, which reduces limitations, improves production efficiency, and increases the application flexibility of the equipment.

[0035] When the electric valve 30 and electronic flow meter 31 are activated, the metal powder in the storage chamber 27 is transported to the forming tank 19 through the conveying pipe 29. The electronic flow meter 31 measures the amount of conveyed. When the set amount is reached, the information is sent to the electric valve 30, the electric valve 30 closes, the transport stops, and the second electric push rod 24 drives the metal powder box 26 to return to its original position. The amount of metal powder filled into the forming tank 19 each time is precisely controlled, ensuring the consistency of the quality of each gear.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
