[0002] With the development of industrial technology, the raw materials required for industrial production are becoming more and more diverse.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0046] Embodiment 1

[0047] Refer to Figures 1-4, an alloy powder forming die convenient for removing waste materials, comprising a main body assembly 1, and the main body assembly 1 includes: a base 11, with a die cavity 12 opened at the top thereof; struts 13, symmetrically arranged on the top of the base 11; a lower punch mechanism 14, arranged on the struts 13; a cleaning assembly 2 is arranged on the base 11, the die cavity 12 and the struts 13, and the cleaning assembly 2 includes: an electric push rod 21, arranged in the inner cavity of the base 11; a push plate 22, arranged at the top of the electric push rod 21, and the push plate 22 is slidably connected to the inner wall of the die cavity 12; an air pipe 23, symmetrically arranged and penetrating through a cross frame between the struts 13; a jet head 24, connected to one end of the air pipe 23 close to the die cavity 12 in a penetrating manner; a motor 25, arranged on the outer side wall of the strut 13, and the output shaft of the motor 25 penetrates through the strut 13; a scraping mechanism 26, arranged on the strut 13 and the motor 25. The scraping mechanism 26 includes: a reciprocating lead screw 261, rotatably connected between the struts 13, and one end of the reciprocating lead screw 261 is fixedly connected to the output shaft of the motor 25 of the main body assembly 1; a cross bar 262, fixedly connected between the other struts 13; moving blocks 263, symmetrically arranged on the reciprocating lead screw 261 and the cross bar 262, the moving block 263 on the reciprocating lead screw 261 is threadedly connected to the reciprocating lead screw 261, and the other moving block 263 is slidably connected to the cross bar 262; a lower scraper 264, fixedly connected between the moving blocks 263; brackets 265, symmetrically arranged on the top of the lower scraper 264; springs 266, symmetrically arranged on the opposite surfaces of the brackets 265; side scrapers 267, fixedly connected to the opposite ends of the springs 266. A recovery mechanism 27 is arranged on the struts 13 and the base 11, and the recovery mechanism 27 includes: side plates 271, symmetrically arranged between the struts 13; insertion holes 272, symmetrically opened on the right side wall of the base 11; insertion rods 273, inserted into the insertion holes 272; a collection box 274, fixedly connected to one end of the insertion rod 273 away from the base 11.

[0048] During use, the staff adds alloy powder into the mold cavity 12, and the lower punch in the lower punch mechanism 14 moves downward to press and form the alloy powder in the mold cavity 12. After the pressing is completed, the lower punch in the lower punch mechanism 14 is controlled to move upward, and the cleaning component 2 cleans the mold cavity 12 and the lower punch: The staff first starts the electric push rod 21, and the electric push rod 21 pushes the push plate 22 upward. The push plate 22 pushes the finished product at the top and the residual powder in the mold cavity 12 upward together until the upper surface of the push plate 22 is at the same horizontal line as the top of the base 11. Then the electric push rod 21 is turned off. At this time, the staff removes the finished product from the push plate 22, and the scraping mechanism 26 cleans the lower punch: The staff starts the motor 25, and the motor 25 drives the reciprocating lead screw 261 to rotate. The moving block 263 threadedly connected to the reciprocating lead screw 261 drives the lower scraper 264 to reciprocate along the reciprocating lead screw 261. The moving block 263 at the other end of the lower scraper 264 slides on the cross bar 262 accordingly. When the lower scraper 264 moves towards the middle of the lower punch, the side scraper 267 slides past the outer wall of the lower punch and is extruded outward by the lower punch, and compresses the compression spring 266, which facilitates the side scraper 267 to continue scraping the residual powder on the outer wall of the lower punch. At the same time, when the lower scraper 264 moves, it scrapes the powder at the bottom of the lower punch. The scraped powder falls onto the lower base 11. Then the staff starts an air pump (not shown in the drawing) connected to the air pipe 23, and the gas in the air pipe 23 is ejected through the air jet head 24. The air jet head 24 blows away the powder on the base 11 and the push plate 22 together to prevent powder from remaining on the device and affecting the next pressing. The above-mentioned lower punch mechanism 14 adopts a conventional stamping method. For example, a cylinder can be used as the power to push the lower punch at the bottom to press the alloy powder in the mold cavity 12, as long as it can drive the lower punch to stamp and form the powder in the mold cavity 12. The specific structure will not be elaborated here. The recycling mechanism 27 recycles the residual powder to reduce the production cost: When the air jet head 24 blows the powder to the right, the side plates 271 on both sides block the powder from flowing out from both sides, and the powder is blown into the collection box 274 on the right. When the collection box 274 is full of powder, the staff can pull out the insertion rod 273 from the insertion hole 272 by pulling the collection box 274 to disassemble the collection box 274, which is convenient for the staff to pour out the powder.

[0049] Embodiment 2

[0050] On the basis of Embodiment 1, an auxiliary function is added.

[0051] Refer to Figures 1-4, a set of the jacks 272 are symmetrically formed on the right side of the base 11, a support frame 275 is inserted into the jacks 272, and a filter screen 276 is fixedly connected to the support frame 275. The jet head 24 is inclined. The optical axes 3 are symmetrically penetrated and slidably connected to the support 265, the opposite ends of the optical axes 3 are fixedly connected to the opposite ends of the side scraper 267, and the spring 266 is sleeved outside the optical axes 3.

[0052] Before the powder is blown to the front of the collection frame 274, it needs to pass through the filtration of the filter screen 276. The filter screen 276 filters out the alloy powder that is adhered to each other after stamping and cannot be used again, so that the powder meeting the requirements of reuse falls into the collection frame 274, avoiding affecting the quality of the subsequent pressed products. At the same time, the staff can also pull out the support frame 275 from the upper jack 272 to facilitate cleaning the impurities in the filter screen 276 and avoid affecting the normal filtering effect of the filter screen 276. The inclined design of the jet head 24 is used to control the flow direction of the powder, reduce the scattering of the powder everywhere, and avoid affecting the normal recovery of the recovery mechanism 27. During the process that the side scraper 267 moves under the extrusion of the lower punch and compresses the spring 266, the optical axes 3 extend out of the support 265 along with the movement of the side scraper 267. The optical axes 3 are used to limit the lateral expansion and contraction of the spring 266, avoiding the spring 266 from being skewed when the side scraper 267 moves along the outer wall of the lower punch, affecting the cleaning effect of the side scraper 267 on the outer wall of the lower punch and reducing the service life of the spring 266.

[0053] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
