[0023] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0024] Refer to Figures 1 - 4 , including a mold ejection table 1 and a mold feeding table 2 on one side of the mold ejection table 1. The mold feeding table 2 is responsible for feeding dust. A feeding box body 21 is slidably connected to the mold feeding table 2. The feeding box body 21 is pushed by a pushing cylinder fixedly connected to the tabletop of the mold feeding table 2. Both the upper end and the bottom of the coating box body are open. By pushing the feeding box body 21, the bottom opening of the coating box body communicates with the mold ejection groove 11 opened on the mold ejection table 1, so that the powder in the feeding box body 21 falls into the mold ejection groove 11 for pressing, and then the ejection device in the ejection groove ejects the finished product.
[0025] Refer to Figures 1 - 4 , a feeding plate 24 is connected between the mold feeding table 2 and the mold ejection table 1. The feeding box body 21 slides on the feeding plate 24 in the direction towards the mold ejection groove 11. A driving cylinder 23 is fixedly connected to the bottom of the mold feeding table 2. The feeding plate 24 is slidably connected to the mold feeding table 2. The driving cylinder 23 can drive the feeding plate 24 to slide and can separate the connection relationship between the feeding plate 24 and the tabletop of the mold ejection table 1. A feeding buffer groove 26 is opened on the mold feeding table 2. The feeding plate 24 is slidably connected in the feeding buffer groove 26. A limiting rod 27 is fixedly connected to the end of the feeding plate 24. The limiting rod 27 extends into the side wall of the feeding buffer groove 26 and is slidably connected, which can ensure the stability of the feeding plate 24 during the sliding process.
[0026] Refer to Figures 1 - 4A first sensing member 22 is provided on the feed box body 21, and the first sensing member 22 is linked to the edge of the mold ejection groove 11. The first sensing member 22 is set to sense the edge of the groove body of the mold ejection groove 11. When the feed box body 21 is filled with powder into the mold ejection groove 11, it starts to move to produce an induction effect with the edge of the mold ejection groove 11, which can trigger an electrical signal. A cleaning member 25 linked to the first sensing member 22 is provided at the front end of the feed box body 21. The length of the cleaning member 25 is greater than the width of the feed plate 24. When the electrical signal is triggered, the cleaning member 25 will be energized. The cleaning member 25 is an electrically driven brush that can clean the feed plate 24 under electrical drive.
[0027] refer to Figures 1 - 4 The cleaning member 25 is fixedly connected with a connecting rod 251, and a clearance groove 252 is provided on the feeding box body 21 for the connecting rod 251 to extend into. The top of the clearance groove 252 is fixedly connected with an elastic driving member 253, and the connecting rod 251 extends into the elastic driving member 253, and a rotating rod 254 is rotatably connected in the elastic driving member 253. A placement groove 255 is provided on the surface of the elastic driving member 253, and a torsion spring is fixedly connected inside the rotating rod 254. The cleaning member 25 can be lifted by rotating the connecting rod 251 on the cleaning member 25, and the cleaning member 25 is ensured not to contact the surface of the feeding table when it is not needed. The force of the torsion spring is always in the direction away from the feeding table, which can stabilize the position of the cleaning member 25. When it is needed, the connecting rod 251 is rotated to put down the cleaning member 25 for reuse, thereby ensuring that the cleaning member 25 is isolated from the surface of the feeding table when it is not electrically triggered, thereby ensuring the service life of the bristles of the cleaning member 25.
[0028] refer to Figures 1 - 4 A second sensing member 28 is fixedly connected to the side wall of the feed box body 21. The second sensing member 28 and the end of the feed plate 24 are linked. The second sensing member 28 can sense the end of the feed plate 24, and can prevent the push cylinder from driving the feed box body 21 to move so that the bottom discharge port and the feed buffer groove 26 are connected, and can stop at the end of the feed platform in time to pause the contraction of the push cylinder.
[0029] The working principle of this mechanism is as follows: When the die pressing operation is carried out, the powder is put into the feeding box body 21, and the pushing cylinder is started. At this time, the cleaning part 25 is manually lifted. When the feeding box body 21 makes the opening at its bottom communicate with the opening of the die ejecting groove 11 through the feeding plate 24, the powder enters the die ejecting groove 11. At this time, the cleaning part 25 is manually lowered, and the pushing cylinder is started again. At the same time, the first sensing part 22 is started. When the pushing cylinder drives the feeding box body 21 to move to the position where the first sensing part 22 senses that it is at the edge of the die ejecting groove 11, the bottom opening of the entire feeding box body 21 is already misaligned with the die ejecting groove 11. At this time, the first sensing part 22 transmits an electrical signal to the cleaning part 25 and energizes it, and the cleaning part 25 starts to work to clean the area on the surface of the feeding plate 24 and the die ejecting table 1 that has passed through during feeding. When the feeding box body 21 moves to the position where the second sensing part 28 senses the edge of the feeding table, the pushing cylinder stops working. The second sensing part 28 transmits an electrical signal to the driving cylinder 23 and activates the driving cylinder 23, so that the feeding plate 24 extends into the feeding buffer groove 26 along the direction of the limiting rod 27. At this time, the powder remaining in the gap between the feeding plate 24 and the die ejecting table 1 drops. The driving cylinder 23 is pushed in the reverse direction again to restore the contact relationship between the feeding plate 24 and the die ejecting table 1, thus completing the entire cleaning process.
[0030] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be understood to be within the protection scope of the present invention.
