The powder metallurgy forming machine includes a mold and the aforementioned powder metallurgy powder feeder. This invention enables the quantitative filling of multiple powders within one powder feeding cycle, simplifies the tooling and mold structure, and improves production efficiency. However, in implementing this technical solution, at least the following problems were found in the existing technology.
[0004] The metering plate is a very important component of the powder feeder. In order to adapt to the characteristics of different powder materials, powder feeding requirements and process requirements, and to achieve accurate metering control and uniform powder feeding, different types of metering plates are required. However, most existing powder feeders have fixed installation of the metering plate, and the replacement process of the metering plate is too cumbersome. It is not possible to use a snap-fit method to quickly assemble the metering plate, which will directly affect the working efficiency of the powder feeder. Summary of the Invention
[0005] To address the problems existing in the prior art, this utility model provides a powder feeder for powder metallurgy, which solves the problem that most existing powder feeders have fixed installation of the metering plate, making the replacement process of the metering plate too cumbersome and unable to use a snap-fit method for quick assembly of the metering plate.
[0006] This utility model is implemented as follows: a powder feeder for powder metallurgy includes a base and a fixed frame fixed to one side of the top of the base by an I-beam. A first electric slide rail is fixed on the base, and an mounting plate is provided on the first electric slide rail. A second electric slide rail is fixed on the mounting plate, and a mold plate with a mold groove on the top is provided on the second electric slide rail. One end of the mold plate passes through the fixed frame and extends outward. A metering plate is attached to the fixed frame, and a base plate is attached to the metering plate. A powder box with multiple internal chambers is embedded in the base plate. Multiple discharge holes communicating with the chambers are sequentially opened along the front-back direction on the metering plate. Multiple feed pipes communicating with the chambers are sequentially connected along the front-back direction on the powder box. A discharge hole communicating with the discharge holes and the mold groove is opened on the fixed frame. An electric push rod is fixed to the back of the top of the fixed frame. A retainer is fixed to the piston rod of the electric push rod, and a docking assembly for cooperating with the metering plate and the base plate is provided on the retainer.
[0007] As a preferred embodiment of this utility model, the docking assembly includes limiting seats symmetrically fixed to the fixed frame in the left-right direction. Both sides of the bottom of the base plate are attached to the limiting seats. Each set of limiting seats is fixed with a baffle plate whose bottom is attached to the outer side of the top of the base plate. A T-shaped groove is opened on the back of each set of measuring plates. A locking seat is engaged with the T-shaped groove and the card seat. An L-shaped frame is fixed to the top of the front of the locking seat. A protrusion is fixed to the back of the base plate. The end of the L-shaped frame away from the locking seat is inserted into the protrusion.
[0008] As a preferred embodiment of this invention, the locking seat has an I-shaped structure.
[0009] As a preferred embodiment of this invention, the height of the locking seat is greater than the height of the measuring plate.
[0010] As a preferred embodiment of this utility model, each set of base plates has chamfers on all four sides.
[0011] As a preferred embodiment of this utility model, a fixed slide is fixed on the left side of the top of the base, and a fixed track is fixed on the left side of the bottom of the mounting plate, with the top of the fixed slide slidably disposed within the fixed track.
[0012] As a preferred embodiment of this utility model, a support frame is fixed to the right side of the top of the mounting plate, and a limiting roller with its top end attached to the bottom of the mold plate is rotatably mounted on the support frame. The right side of the top of the mold plate is attached to the top of the inner cavity of the fixed frame.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This invention, by setting up a docking component, utilizes a limiting seat and a baffle plate to pre-position the base plate and the metering plate, allowing them to fit together. With the cooperation of the locking seat, they can be simultaneously engaged with the T-slot and the card holder, enabling rapid engagement and positioning of the metering plate and the card holder. Furthermore, with the cooperation of the L-shaped frame, they can be quickly inserted with the protrusion, thus rapidly forming a single integrated structure from the base plate, metering plate, powder box, locking seat, and card holder. This allows the electric push rod to drive the movement of this integrated structure. The snap-fit method allows for quick assembly of the metering plate, and disassembly is equally convenient, requiring only the removal of the locking seat. This allows users to freely replace different models of metering plates as needed. Attached Figure Description

[0022] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0023] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0024] As shown in Figures 1 to 5, the powder feeder for powder metallurgy provided in this embodiment of the present invention includes a base 1, a controller mounted on the base 1, and a fixing frame 6 fixed to one side of the top of the base 1 by means of an I-beam frame. A first electric slide rail 2 is fixed on the base 1, a mounting plate 3 is mounted on the first electric slide rail 2, a second electric slide rail 4 is fixed on the mounting plate 3, a mold plate 5 with a mold groove on the top of the second electric slide rail 4 is mounted on the second electric slide rail 4, one end of the mold plate 5 passes through the fixing frame 6 and extends outward, a metering plate 12 is attached to the fixing frame 6, a base plate 13 is attached to the metering plate 12, and a powder box 14 with multiple internal chambers is embedded in the base plate 13. Multiple sets of discharge holes 24 connected to the chamber are sequentially opened along the front-to-back direction. Multiple sets of feed pipes 15 connected to the chamber are sequentially opened along the front-to-back direction. The fixed frame 6 is provided with a discharge hole 11 connected to the discharge hole 24 and the mold groove. An electric push rod 18 is fixed to the back of the top of the fixed frame 6. The piston rod of the electric push rod 18 is fixed with a card seat 19. The card seat 19 is provided with a docking component that works with the metering plate 12 and the base plate 13. By setting the docking component, the metering plate 12 can be quickly assembled by snap-fitting. Disassembly is also convenient, as only a single part needs to be pulled out. This allows users to freely replace different models of metering plates 12 as needed.
[0025] As a preferred embodiment of this utility model, the docking assembly includes limiting seats 16 symmetrically fixed to the fixed frame 6 in the left-right direction. Both sides of the bottom of the base plate 13 are attached to the limiting seats 16. Each limiting seat 16 has a baffle plate 17 whose bottom is attached to the outer side of the top of the base plate 13. A T-slot 21 is provided on the back of each measuring plate 12. A locking seat 20 is engaged with the T-slot 21 and the card holder 19. An L-shaped frame 23 is fixed to the top of the front of the locking seat 20. A protrusion 22 is fixed to the back of the base plate 13. 3. The end away from the locking seat 20 is inserted into the protrusion 22. The design of the limiting seat 16 and the baffle plate 17 can pre-position the base plate 13 and the metering plate 12. The design of the locking seat 20 can quickly snap the metering plate 12 and the card seat 19 into position. With the assistance of the L-shaped frame 23 and the protrusion 22, the base plate 13, the metering plate 12, the powder box 14, the locking seat 20 and the card seat 19 can be quickly fixed into an integral structure, and the metering plate 12 can be quickly assembled. The snap-fit method also makes disassembly convenient.
[0026] As a preferred embodiment of this utility model, the locking seat 20 has an I-shaped structure, which facilitates quick engagement between the locking seat 20 and the T-slot 21 and the card seat 19, and simultaneously improves the engagement stability to prevent detachment.
[0027] As a preferred embodiment of this utility model, the height of the locking seat 20 is greater than the height of the measuring plate 12. This design with different heights improves the stability of the locking seat 20 during docking and makes it easier for users to lift and move the locking seat 20.
[0028] As a preferred embodiment of this utility model, each set of base plates 13 has chamfers on all four sides. The chamfer design makes it easy for the base plates 13 to be quickly inserted between the limiting seat 16 and the cover plate 17, thus improving the installation efficiency.
[0029] As a preferred embodiment of this utility model, a fixed slide 7 is fixed on the left side of the top of the base 1, and a fixed track 8 is fixed on the left side of the bottom of the mounting plate 3. The top of the fixed slide 7 is slidably disposed in the fixed track 8. The design of the fixed slide 7 and the fixed track 8 improves the overall stability of the mounting plate 3 when it moves, and prevents one end of the mounting plate 3 from easily falling down when it moves.
[0030] As a preferred embodiment of this utility model, a support frame 9 is fixed on the right side of the top of the mounting plate 3. A limiting roller 10 with its top end attached to the bottom of the mold plate 5 is rotatably mounted on the support frame 9. The right side of the top of the mold plate 5 is attached to the top of the inner cavity of the fixed frame 6. The design of the support frame 9 and the limiting roller 10 can slide and position the mold plate 5, improve its overall stability when moving, and make it fit tightly with the fixed frame 6.
[0031] The working principle of this utility model:
[0032] Referring to Figures 1 to 5, the user activates the first electric slide rail 2 and the second electric slide rail 4 via the controller, thereby freely adjusting the position of the mold plate 5 until the mold groove on the mold plate 5 is quickly moved to the bottom of the discharge hole 11. At this time, various powder materials can be poured into different chambers in the powder box 14 through multiple sets of feeding pipes 15. The user then activates the electric push rod 18, which drives the card holder 19 and the metering plate 12 to move, thereby pushing the base plate 13 and the powder box 14 to move synchronously until the discharge hole 24 is moved to the discharge hole 11, so that various powder materials can be poured one by one into the preset mold groove on the mold plate 5. If different models of discharge holes 24 are required, it is necessary to adjust the discharge hole 24 accordingly. When replacing the measuring plate 12, the user lifts the locking seat 20 and removes it from the T-slot 21 and the card holder 19, thus releasing the locking state of the measuring plate 12 and the base plate 13. The user then pulls the measuring plate 12 to one side to remove it from the inside of the limiting seat 16. The user then reinserts the measuring plate 12 to be used between the two sets of limiting seats 16 from one side until one end is in contact with the card holder 19. The user then re-locks the locking seat 20 into the T-slot 21 and the card holder 19, thus restoring the base plate 13, measuring plate 12, powder box 14, locking seat 20, and card holder 19 into a single integrated structure. The user can then control the movement of the measuring plate 12 again using the electric push rod 18.
