[0031] like Figure 1-Figure 6 As shown;

[0032] A metallurgical powder forming device comprises a workbench 1.

[0033] In this embodiment: after checking the public (announcement) number: CN218836084U discloses a molding equipment for the production of powder metallurgy products. This technology discloses "including a box body, both sides of the middle of the inner wall of the box body are fixedly connected to limit plates, a bottom plate is slidably connected between the two limit plates, a plurality of lower molds are fixedly connected to the top of the bottom plate, a hydraulic rod is fixedly connected to the middle of the top of the box body, the output end of the hydraulic rod passes through the box body and is fixedly connected to the top plate, a plurality of upper molds are fixedly connected to the bottom of the top plate, and each upper mold corresponds to each lower mold, and the technical scheme is disclosed. It is simple to operate and easy to use, and can effectively improve the production efficiency of the equipment. It can effectively press and mold the powder raw materials in multiple lower molds at the same time, avoiding the situation that traditional equipment needs a single mold for pressing and molding, which affects the processing efficiency of the equipment, and effectively guarantees the use effect of the equipment and other technical effects".

[0034] When the existing molding equipment is in use, its bottom mold is in a fixed installation state. When the mold needs to be replaced to meet different molding requirements, the operation time is long, and it cannot have the function of ejecting and discharging materials. The material needs to be taken out manually, which has certain limitations. Combined with actual use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, a quick-loading mold mechanism 2 and a flexible lifting mechanism 4 are added to the application document.

[0035] According to the above content, in order to facilitate the quick assembly of the bottom mold, the top of the workbench 1 is fixedly connected with a fixing frame 3, and the left and right sides of the top of the fixing frame 3 are bolted with hydraulic cylinders 5, the output end of the hydraulic cylinder 5 is fixedly connected with an integrated board 7, and the bottom of the integrated board 7 is installed with an upper mold head 6. The top of the workbench 1 is installed with a quick-loading mold mechanism 2, and the quick-loading mold mechanism 2 includes a lower mold base 204 and a positioning shaft 208. The left and right sides of the lower mold base 204 are fixedly connected with an expansion plate 201, and the top movable sleeve on the surface of the positioning shaft 208 is provided with an anti-slip rod 207, and the bottom of the inner cavity of the lower mold base 204 is installed with a displacement template 205.

[0036] In this embodiment: first adjust the anti-slip rod 207 to a left-right horizontal state so that the short end of the anti-slip rod 207 is aligned with the card slot 203, then under the positioning action of the expansion plate 201 and the storage slot 202, the lower mold base 204 is accurately and quickly placed, and then the anti-slip rod 207 is rotated ninety degrees around the positioning axis 208, as shown in the figure of the specification Figure 5 As shown, in this state, the anti-drop rod 207 can buckle the expansion board 201, thereby preventing the expansion board 201 and the lower mold base 204 from moving upward, thereby ensuring the installation stability of the lower mold base 204.

[0037] In an optional embodiment: a slot 203 for use with the anti-slip rod 207 is provided on the surface of the expansion plate 201 , and an arc-shaped slot 206 for use with the anti-slip rod 207 is provided on the top of the workbench 1 .

[0038] In this embodiment, the purpose of the slot 203 and the arc slot 206 is to meet the space requirement for the anti-drop rod 207 to rotate forward and backward by 90 degrees.

[0039] In an optional embodiment: a receiving groove 202 is opened on the top of the workbench 1 , and the inner cavity of the receiving groove 202 is connected with the inner cavity of the arc-shaped groove 206 .

[0040] In this embodiment, the storage slot 202 is used to provide an installation and placement space for the expansion board 201 .

[0041] According to the above content, in order to be able to remove the pressed and formed materials and facilitate the staff to take them, a flexible lifting mechanism 4 is installed at the bottom of the workbench 1, and the flexible lifting mechanism 4 includes an electric push rod 404. The output end of the electric push rod 404 is fixedly connected to an auxiliary plate 402, and a column 403 is fixedly installed on the top of the auxiliary plate 402. An electric suction cup 401 is embedded in the center of the top of the column 403.

[0042] In this embodiment: after placing the powder to be processed in the lower die seat 204, the hydraulic cylinder 5 is controlled to extend, which will drive the integrated board 7 to move downward, so that the upper die head 6 enters the corresponding lower die seat 204 to complete the pressing process of the powder, and then the hydraulic cylinder 5 is controlled to reset, and the electric push rod 404 is controlled to extend, so that the column 403 enters the lower die seat 204, and the electric suction cup 401 is in contact with the bottom of the displacement template 205. The electric suction cup 401 is controlled to work to tightly adsorb the displacement template 205. At this time, as the electric push rod 404 is further extended, the displacement template 205 holding the molding material will gradually move upward, which greatly facilitates the staff to take it out. Due to the adsorption between the electric suction cup 401 and the displacement template 205, when the electric push rod 404 moves down and resets, the displacement template 205 naturally moves down and resets to the lowest point in the lower die seat 204.

[0043] In an optional embodiment: an auxiliary frame 405 is fixedly connected to the center of the bottom of the workbench 1, the number of the electric push rods 404 is two, and the connection between the surface of the electric push rod 404 and the auxiliary frame 405 is connected by bolts.

[0044] In this embodiment: the auxiliary frame 405 is used to meet the fixed installation requirements of the electric push rod 404.

[0045] In an optional embodiment: the distance between the top of the auxiliary plate 402 and the bottom of the workbench 1 is greater than the vertical length of the lower mold base 204, the upper mold head 6 is adapted to the lower mold base 204, the surface of the displacement template 205 is in sliding contact with the inner wall of the lower mold base 204, and the top of the column 403 passes through the workbench 1 and extends to the inner cavity of the lower mold base 204.

[0046] In this embodiment, this design can ensure the travel space of the auxiliary plate 402 , and when the auxiliary plate 402 drives the column 403 to move upward, the molding material in the lower mold base 204 can be easily moved out of the lower mold base 204 .

[0047] The working principle and use process of the utility model are as follows: first, the anti-slip rod 207 is adjusted to a left-right horizontal state so that the short end of the anti-slip rod 207 is aligned with the card slot 203, and then the lower mold base 204 is accurately and quickly placed under the positioning action of the expansion plate 201 and the storage slot 202, and then the anti-slip rod 207 is rotated ninety degrees around the positioning axis 208, as shown in the attached figure of the specification. Figure 5 As shown, in this state, the anti-slip rod 207 can buckle the expansion plate 201, thereby preventing the expansion plate 201 and the lower die seat 204 from moving up, ensuring the installation stability of the lower die seat 204; after the powder to be processed is placed in the lower die seat 204, the hydraulic cylinder 5 is controlled to extend to work, which will drive the integrated board 7 to move downward, so that the upper die head 6 enters the corresponding lower die seat 204 to complete the pressing process of the powder, and then the hydraulic cylinder 5 is controlled to reset, and the electric push rod 404 is controlled to extend to work, so that the column 403 enters The electric suction cup 401 is in contact with the bottom of the displacement template 205, and the displacement template 205 can be tightly adsorbed by controlling the electric suction cup 401. At this time, as the electric push rod 404 is further extended to work, the displacement template 205 holding the molding material will gradually move upward, which greatly facilitates the staff to take it out. Due to the adsorption between the electric suction cup 401 and the displacement template 205, when the electric push rod 404 moves down and resets, the displacement template 205 naturally moves down and resets to the lowest point in the lower mold base 204.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
