[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-4This utility model provides a material adding device for a powder molding machine, including a carrier frame 5, a connecting frame 3 on the top of the carrier frame 5, a linear motor 4 for driving the connecting frame 3 to move on the top of the carrier frame 5, a support frame 2 on the top of the connecting frame 3, and the support frame 2 and the connecting frame 3 are connected by a sliding component. A storage tank 1 is welded to the top of the support frame 2, and a guide pipe 13 connected to the storage tank 1 is welded to the bottom outer wall of the storage tank 1. The bottom outer wall of the storage tank 1 and one side of the guide pipe 13 are connected by a guide pipe 13. A fixing bracket 17 is bolted in place. A guide shell 11 is provided on one side of the fixing bracket 17, and a first cylinder 15 is installed on the other side of the fixing bracket 17 to move the guide shell 11. A slot 12 penetrating the guide shell 11 is opened on the upper surface of the guide shell 11, and the slot 12 corresponds to the guide tube 13. A second baffle 14 is provided on one outer wall of the guide shell 11, and the upper surface of the second baffle 14 is on the same plane as the upper surface of the guide shell 11. A welded joint is provided on the bottom outer wall of the guide shell 11. The discharge pipe 10 is connected to the mold. A first baffle 9 is welded to the bottom of the fixed frame 17 to block the discharge port at the bottom of the discharge pipe 10. When the linear motor 4 is started, it drives the connecting frame 3 to move towards the molding machine, moving the first baffle 9 above the mold cavity. At the same time, the material in the storage tank 1 will enter the guide shell 11 through the guide pipe 13 and the slot 12 until the guide shell 11 is full of material. Then, the first cylinder 15 is started, and the first cylinder 15 pushes the guide shell 11 to move, so that the guide pipe 13 and the slot are connected. 12 is disengaged, and the guide pipe 13 is moved to the position of the second baffle 14 to block the guide pipe 13 and stop feeding. At the same time, the discharge pipe 10 is disengaged from the first baffle 9, and the material in the guide shell 11 will enter the mold cavity through the discharge pipe 10, thus realizing the feeding. This not only saves manpower, but also solves the problem of relying heavily on the operator's experience and feeling, and being unable to accurately control the weight of powder filled into the mold cavity each time. Since the internal volume of the guide shell 11 is fixed, the material added each time is the same.

[0024] In this embodiment, the sliding assembly includes several I-shaped sliding rods 7 fixed to the top of the connecting frame 3 by bolts. The several I-shaped sliding rods 7 are located at the four corners of the connecting frame 3 and are slidably connected to the support frame 2. Two rubber pads 8 are sleeved on the outer side of the I-shaped sliding rods 7, and the two rubber pads 8 are located on the upper and lower surfaces of the support frame 2 respectively and fill the gap. A vibration motor 6 is installed on the bottom inner wall of the support frame 2. By starting the vibration motor 6, the vibration motor 6 drives the support frame 2 to vibrate up and down along the I-shaped sliding rods 7 in cooperation with the rubber pads 8. During the up and down vibration of the support frame 2, the storage tank 1 will also vibrate, so that the material in the storage tank 1 can be more evenly distributed, avoiding uneven accumulation of material, ensuring the smoothness of the material entering the guide shell 11, and ensuring that there are no gaps inside the guide shell 11 when material is added to it. This design reduces the hard impact between the support frame 2 and the I-shaped slide bar 7 during vibration, thereby reducing equipment wear and extending its service life. Simultaneously, the elastic properties of the rubber pad 8 provide cushioning, making the vibration of the support frame 2 more stable and preventing material spillage or equipment damage caused by severe vibration.

[0025] It should be noted that the vibration motor 6 used in this application is prior art, model: VB 15 / 2510. A vibration motor is a motor that converts electrical energy into mechanical vibration energy. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0026] In this embodiment, a through groove 22 is provided on the top of the guide shell 11. A slider 19 that contacts the inner wall of the guide shell 11 is slidably connected in the through groove 22. A power assembly for driving the slider 19 to move up and down is provided on the top of the guide shell 11. The power assembly includes a mounting bracket 21 that is fixed to the top of the guide shell 11 by bolts and located on one side of the through groove 22. A second cylinder 20 is mounted on the upper surface of the mounting bracket 21. The piston end of the second cylinder 20 passes through the mounting bracket 21 and is fixed to the slider 19. By activating the second cylinder 20, the piston end of the second cylinder 20 drives the slider 19 to move up and down, thereby indirectly changing the volume of the guide shell 11, thereby achieving flexible and precise control of the amount of material entering the mold cavity.

[0027] In this embodiment, both the bottom inner walls of the storage tank 1 and the guide shell 11 are provided with inclined surfaces 18. The inclined surface 18 of the bottom inner wall of the storage tank 1 is inclined towards the guide pipe 13, and the inclined surface 18 of the bottom inner wall of the guide shell 11 is inclined towards the discharge pipe 10. The inclined surface 18 not only improves the efficiency of material conveying, but also effectively prevents materials from accumulating at the bottom of the storage tank 1 and the guide shell 11.

[0028] In this embodiment, the diameter of the slot 12 is the same as the inner diameter of the guide pipe 13. When the guide pipe 13 is in the position of the slot 12, the first baffle 9 blocks the outlet of the discharge pipe 10. The guide pipe 13 is provided with a baffle on one side of the second cylinder 20, and the baffle is in contact with the guide shell 11. The baffle can prevent material leakage after the guide pipe 13 is separated from the slot 12.

[0029] In this embodiment, a telescopic rod 16 is fixed to one side of the fixed frame 17 and located at the bottom of the first cylinder 15 by bolts. The telescopic end of the telescopic rod 16 passes through the fixed frame 17 and is fixed to the guide shell 11. The telescopic rod 16 plays a guiding role, which improves the smoothness and stability of the guide shell 11 when it moves.

[0030] It should be noted that the linear motor 4, the first cylinder 15 and the second cylinder 20 used in this application are all prior art. Those skilled in the art can set them according to actual needs, and they will not be described in detail here.

[0031] The use of this utility model involves the following steps: S1: First, start the vibration motor 6. Through cooperation with the rubber pad 8, the vibration motor 6 drives the support frame 2 to vibrate up and down along the I-shaped slide bar 7. During the up and down vibration of the support frame 2, the storage bucket 1 and the guide shell 11 will also vibrate. S2: Then start the linear motor 4, which drives the connecting frame 3 to move towards the molding machine, moving the first baffle 9 and the discharge pipe 10 to the top of the mold cavity. At the same time, the material in the storage tank 1 will enter the guide shell 11 through the guide pipe 13 and the slot 12 until the guide shell 11 is filled with material. S3: Then, the first cylinder 15 is started. The first cylinder 15 pushes the guide shell 11 to move, so that the guide tube 13 is separated from the slot 12. At the same time, the guide tube 13 will move to the position of the second baffle 14 and be blocked by the second baffle 14. At the same time, the discharge tube 10 is separated from the first baffle 9, and the material in the guide shell 11 will enter the mold cavity through the discharge tube 10.
