It is a powder forming machine that uses a servo motor to drive the screw to rotate the upper punch, mother mold, and lower punch to move up and down. The servo press adopts advanced mechanical, electrical, pneumatic, and instrument integrated control and drive technology. It is mainly suitable for the production of inductors, magnetic cores, powder metallurgy, and mechanical parts, mainly structural parts.

[0003] For example, the public document with application number 201820580818.9 discloses a powder feeding device of a powder forming machine. The utility model acts on the powder in the powder shoe through the back-and-forth movement of the powder pushing plate, so that the powder enters the mold cavity evenly, thereby adding powder evenly and ensuring the quality of the pressed product; and the back-and-forth movement of the powder pushing plate also speeds up the speed at which the powder enters the mold cavity, shortens the powder adding time, eliminates the need to stop and wait, and improves production efficiency. The powder feeding device used in the powder forming machine belongs to a group of indispensable feeding structural parts in the powder forming machine and belongs to the category of the powder forming machine. However, the feeding mechanism of the powder feeding is difficult to ensure the uniformity of the quality of the feeding material each time, which may result in a certain amount of difference in each powder feeding, resulting in inconsistent quality of the molding material each time, thereby affecting the overall quality of the material produced by the molding machine.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a powder forming machine with a material quantity monitoring effect is proposed. Utility Model Content

[0023] Furthermore, the control box 2 is integrated with an automated electronic control unit and an external control panel;

[0024] By adopting the above technical solution, the control box 2 is used to control the working sequence and process of the entire device.

[0025] Furthermore, the bottom right side of the inner surface of the material holding box 501 is set as an inclined surface;

[0026] By adopting the above technical solution, the material can flow to the through hole 502 better.

[0027] Furthermore, the bottom of the material box 501 is in contact with the bottom of the inner surface of the through cavity 3;

[0028] By adopting the above technical solution, the bottom end of the through hole 502 is also fitted with the bottom of the inner surface of the through cavity 3, thereby preventing the material inside the material box 501 from leaking.

[0029] Furthermore, the shape of the movable plate 504 is set to be "L"-shaped, the vertical plate body is higher than the upper edge of the through cavity 3, and the horizontal plate body can cover the through hole 502;

[0030] By adopting the above technical solution, when the material box 501 moves right after being refilled, the movable plate 504 will be pushed to the left by the left edge of the through cavity 3, thereby opening the through hole 502 for a second time.

[0031] Further, the guide rod 505 protrudes out of the material box 501;

[0032] By adopting the above technical solution, the inner wall of the workbench 1 will push the guide rod 505 to drive the movable plate 504 to move in the material box 501, thereby blocking the through hole 502.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, a fixed plate 6 is fixedly provided on the upper inner side of the surface of the workbench 1, a cylinder 7 is fixedly installed on the middle part of the upper surface of the fixed plate 6, four movable rods 8 are slidably penetrated at the four corners of the surface of the fixed plate 6, a pushing plate 9 is fixedly provided on the bottom end of the movable rod 8, a spring 10 is sleeved on the surface of the pushing plate 9 and fixedly installed on the outer side of the movable rod 8, the upper end of the spring 10 is fixedly connected to the fixed plate 6, an extrusion molding head 11 is fixedly provided in the middle part below the surface of the pushing plate 9, a molding groove 12 is provided below the inner surface of the workbench 1 just below the extrusion molding head 11, a discharge port 13 is provided at the bottom left side of the outer surface of the workbench 1, a base 14 is fixedly provided at the bottom end of the workbench 1, an electric push rod 15 is fixedly provided on the inner surface bottom of the base 14, a pressure sensor plate 16 is fixedly provided on the upper end of the electric push rod 15, and the pressure sensor plate 16 is slidably fitted at the bottom of the inner surface of the molding groove 12.

[0034] Furthermore, the middle portion above the surface of the push plate 9 is fixedly connected to the bottom telescopic end of the cylinder 7 .

[0035] By adopting the above technical solution, the cylinder 7 can push the propulsion plate 9 to move the extrusion molding head 11 downward, and perform die-casting molding on the material in the molding groove 12.

[0036] Furthermore, the upper end of the movable rod 8 slides through the fixed plate 6 .

[0037] By adopting the above technical solution, the movable rod 8 makes the downward movement of the propulsion plate 9 and the extrusion molding head 11 more stable.

[0038] Furthermore, the lower end of the spring 10 itself is fixed to the propulsion plate 9 , and the upper end is fixed to the fixing plate 6 .

[0039] By adopting the above technical solution, the push plate 9 moves downward to pull the spring 10 to extend, and the downward impact force of the extrusion molding head 11 will be reduced under the elastic tension of the spring 10 itself.

[0040] Furthermore, the diameter of the forming groove 12 matches that of the through hole 502 .

[0045] Furthermore, the electric push rod 15 can push the pressure sensor plate 16 to move, and the maximum upward extension can make the upper surface of the pressure sensor plate 16 and the top of the molding groove 12 remain level.

[0046] By adopting the above technical solution, the formed material can be directly pushed out and demoulded.

[0047] Working principle: When using the powder forming machine with material quantity monitoring effect, first, put the powder material in large quantities into the material box 501, then start the electric control guide rail 4, the electric control guide rail 4 pushes the material box 501 to move to the left through the slide groove 503, and the through hole 502 moves in contact with the bottom of the control box 2. When the through hole 502 is aligned with the forming groove 12, the powder material will automatically fall into the forming groove 12 for automatic feeding. At the same time, the guide rod 505 will be limited by the inner wall on the left side of the workbench 1. As the material box 501 continues to move, the inner wall of the workbench 1 will push the guide rod 505 to drive the movable plate 504 to move in the material box 501, thereby blocking the through hole 502, so that the powder material will not continue to be added to the forming groove 1 2, and each quantitative feeding is realized. After the feeding, the material box 501 moves to the right, and the movable plate 504 is pushed to the left by the left edge of the through cavity 3 to reset, thereby opening the through hole 502 for the second time to prepare for the next feeding. Then, the control box 2 starts the cylinder 7 to push the push plate 9 downward, and the movable rod 8 and the extrusion molding head 11 move downward accordingly. The extrusion molding head 11 is used to compress the powder in the molding groove 12 to form the powder. Then, the control box 2 starts the electric push rod 15 to push the pressure sensor plate 16 upward to push out the formed powder. At this time, the material box 501 will move to the left again to feed, and push the formed powder to be discharged from the discharge port 13. This is the working principle of the powder forming machine with material quantity monitoring effect.
