The following description is based on the accompanying drawings. Figures 1-4 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

Therefore, they should not be construed as limitations on this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0030] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0031] In one embodiment of this utility model, such as Figures 1-4As shown, a multi-layer composite powder material integrated molding device is provided, including a stamping mechanism 100, a molding die 200, a powder feeding mechanism 300, and a dust removal mechanism 400. The molding die 200 is disposed at the output end of the stamping mechanism 100 and can move linearly along the stamping direction of the stamping mechanism 100. The powder feeding mechanism 300 is disposed on one side of the molding cavity 500 of the molding die 200 and has at least two sets of output ends, all of which sequentially fill the molding cavity 500 of the molding die 200 with powder. The dust removal mechanism 400 is disposed on the molding die 200 and is used to perform dust removal treatment between two adjacent powder feeding intervals of the powder feeding mechanism 300.
[0032] When multiple different types of powders are involved in filling, different types of powders are sequentially input into the molding cavity 500 in a preset order through the output end of the powder feeding mechanism 300. In the gap between the powder feeding ends of different powders, the stamping mechanism 100 extrudes the powder in the molding cavity 500 into a preset shape, and the dust removal mechanism 400 removes excess powder from the molding cavity 500. This allows different types of powder materials to be pressed and formed in the same molding cavity 500 without the need for additional adhesives. Compared with the traditional powder molding process, which has problems such as cumbersome operation, long time, high cost and easy cracking, the powder molding device provided by this utility model embodiment has independent powder filling, molding and dust removal processes for different types of powders. At the same time, the products formed by two adjacent powder molding processes are processed by the pressing process, which effectively avoids cracking and other problems, and also eliminates the cumbersome process of adding additional adhesives, effectively improving the efficiency of powder molding.
[0033] like Figures 1-4 As shown, in another embodiment of this utility model, the stamping mechanism 100 includes an upper die 110 and a lower die 120, which are arranged opposite each other in a vertical direction. The upper die 110 and the lower die 120 are respectively disposed on both sides of the forming die 200. The output ends of the upper die 110 and the lower die 120 can both move and extend into the forming cavity 500 of the forming die 200 to extrude the powder located in the forming cavity 500 into a preset shape. Since the space reserved in the forming cavity 500 of the forming die 200 is different when filling different powders, the forming die 200 needs to adjust its position relative to the output end of the lower die 120 during different powder fillings. For example, in this embodiment, the output ends of the upper die 110 and the lower die 120 can be adjusted by adjusting the stamping stroke to adapt to the position requirements of the forming die 200.
[0034] like Figures 1-4As shown, in another embodiment of this utility model, the upper mold 110 and the lower mold 120 are both mounted on a mounting frame 130. The molding intermediate mold 200 is slidably connected to the middle position of the mounting frame 130. The molding intermediate mold 200 can move vertically along the length direction of the mounting frame 130 so that the molding cavity 500 moves relative to the output ends of the upper mold 110 and the lower mold 120. The mounting frame 130 includes a top plate 131 and a bottom plate 132, which are connected by a support column 133. The edge of the molding intermediate mold 200 is slidably connected to the support column 133 and can move vertically along the length direction of the support column 133, thereby adjusting its position relative to the output end of the lower mold 120. This allows the molding cavity 500 of the molding intermediate mold 200 to adjust its size during the powder molding process.
[0035] like Figures 1-4 As shown, in another embodiment of this utility model, the molding die 200 is a plate-shaped structure, the molding cavity 500 is formed at the center of the molding die 200, the powder feeding mechanism 300 is disposed at the top of the molding die 200, and the output ends of the powder feeding mechanism 300 are distributed circumferentially around the molding cavity 500. A dust removal channel is reserved on the distribution path of the output ends of the powder feeding mechanism 300 for the movement of the output ends of the dust removal mechanism 400. The distribution of the output ends of the powder feeding mechanism 300 around the molding cavity 500 ensures that the powder feeding stroke of each output end is the same, facilitating the control of the single powder feeding time.
[0036] like Figures 1-4 As shown, in another embodiment of this utility model, the powder feeding mechanism 300 includes at least two sets of powder filling components 310. All the powder filling components 310 are circumferentially spaced around the molding cavity 500. The output ends of all the powder filling components 310 are movable onto the molding cavity 500 and fill the molding cavity 500 with a preset powder. At least one pair of adjacent powder filling components 310 forms the dust removal channel. In this embodiment, the number of powder filling components 310 is three sets, and the three sets of powder filling components 310 and the dust removal mechanism are circumferentially spaced at 90° around the molding cavity 500. The three sets of powder filling components 310 have the same structure and are used to fill different types of powder into the molding cavity 500.
[0037] like Figures 1-4As shown, in another embodiment of this utility model, the powder filling component 310 includes a first guide rail 311 and a movable material box 312. The first guide rail 311 is fixedly disposed on the molding die 200. The first guide rail 311 is provided with a first guide groove 313. The length direction of the first guide groove 313 points to the molding cavity 500. The movable material box 312 is slidably connected in the first guide groove 313. The input end of the movable material box 312 is connected to the output end pipe of an external powder feeding device. The output end of the movable material box 312 is disposed downward. During the process of the movable material box 312 moving along the first guide groove 313, the output end of the movable material box 312 passes through the molding cavity 500. The movable material box 312 is inverted on the end face of the molding die 200. The inner cavity of the movable material box 312 and the end face of the molding die 200 form a receiving cavity for containing powder. During the movement of the movable material box 312, the receiving cavity can cover the molding cavity 500 as the movable material box 312 moves. After the powder in the receiving cavity flows and fills the molding cavity 500, the movable material box 312 is reset. The output end of the upper die 110 and the output end of the lower die 120 approach and squeeze the powder in the molding cavity 500. The output end of the dust removal mechanism 400 moves into the molding cavity 500 to remove excess powder, thereby completing a single powder molding. Another set of adjacent movable material boxes 312 fills the corresponding powder into the molding cavity 500. At this time, the corresponding powder covers the molded workpiece. When the output ends of the upper die 110 and the lower die 120 close, the powder is squeezed and molded on the molded workpiece, thereby completing the composite material powder molding.
[0038] like Figures 1-4 As shown, in another embodiment of this utility model, the first guide rail 311 includes a first guide plate. Two sets of the first guide plates are arranged in a long strip-shaped structure and are distributed in parallel with a gap. The first guide groove 313 is formed between the two sets of the first guide plates, and the edge of the movable material box 312 slides against the first guide plate. The guide plate structure is beneficial to improving the guiding stability of the first guide rail 311. Compared with the groove guide structure formed on the forming mold 200, the added guide plate structure is beneficial to flexibly adjust the position and length of the guide groove, and has greater flexibility.
[0039] like Figures 1-4As shown, in another embodiment of this utility model, the dust removal mechanism 400 includes a second guide rail 410 and a vacuum box 420. A second guide groove is formed on the second guide rail 410. The vacuum box 420 is slidably connected within the second guide groove and can move along the second guide groove. The length direction of the second guide groove points towards the forming cavity 500. The output end of the vacuum box 420 can pass through the forming cavity 500 during movement and extract excess powder from the forming cavity 500. The input end of the vacuum box 420 is arranged downwards, and the output end of the vacuum box 420 is connected to the input end pipe of an external negative pressure device. In this embodiment, the second guide rail 410 includes two sets of second guide plates, which are arranged parallel to each other. The second guide groove is formed between the two sets of second guide plates.
[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
