[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the utility model belong to the scope of protection of the utility model.

[0017] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or position relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0018] Please refer to Figures 1-3 As shown, the present utility model is a multi-station magnetic core processing and forming machine, which includes a bottom plate 1. The upper surface of the bottom plate 1 is connected with a top plate 12 through four support columns 11, and a pair of cross beams 21 are connected between the four support columns 11. A support table 2 is integrally formed between the two cross beams 21. A forming die 3 is placed on the support table 2 in a matching manner. A plurality of forming cavities 31 are arranged on the forming die 3. At the same time, the bottom surface of the top plate 12 is connected with an upper movable plate 14 through a telescopic module B13, and a pressing column 141 inserted into the forming cavity 31 is arranged on the lower surface of the upper movable plate 14. During use, the powder material is pre-filled into the forming cavity 31, then the forming die 3 is placed on the support table 2, and then the telescopic module B13 is controlled to extend to drive the upper movable plate 14 to move downward, so that the pressing column is inserted into the forming cavity 31, and the powder material filled in the forming cavity 31 is compacted and formed.

[0019] Similarly, in order to facilitate the positioning of the forming die 3 placed on the support table 2, a positioning mechanism for positioning the forming die 3 is arranged on the upper surface of the support table 2. The positioning machine includes an L-shaped positioning block 22. Positioning blocks A23 respectively abutting against both sides of the forming die 3 are arranged at both ends of the L-shaped positioning block 22. An L-shaped plate 24 is arranged on one side of the support table 2. A telescopic cylinder 25 is arranged on the inner wall of the L-shaped plate 24. The output end of the telescopic cylinder 25 is connected with an abutting block 26 abutting against one side of the forming die 3. During use, one corner side of the forming die 3 is controlled to be assembled to the position of the L-shaped positioning block 22, and then the telescopic cylinder 25 is controlled to extend to control the movement of the forming die 3, so that the side wall of the forming die 3 abuts against the L-shaped positioning block 22, the positioning block A23 and the abutting block 26 in time, realizing the positioning of the forming die 3.

[0020] Certainly, in order to be able to eject the magnetic core located in the forming die 3 after forming during use, as Figure 4, on the upper surface of the bottom plate 1, a lower movable plate 16 is connected through a telescopic module A15; a support ring 33 is arranged in the forming cavity 31, and a "worker"-shaped movable column is arranged in cooperation with the support ring 33; a convex column 161 is arranged on the upper surface of the movable plate 16 and inserted into the forming cavity 31 and abuts against the bottom end of the movable column; the movable column includes a movable plate A32, and the bottom side surface of the movable plate A32 is connected with a movable plate B35 through a connecting column 34 penetrating through the support ring 33; the convex column 161 is inserted into the forming cavity 31 and abuts against the movable plate B35. Then, after the forming is completed, the telescopic module A15 is controlled to extend to drive the lower movable plate 16 to move upward, so as to conveniently control the convex column 161 to be inserted into the forming cavity 31 to drive the "worker"-shaped movable column to move upward, thereby completing the loosening of the formed magnetic core from the forming cavity 31 and facilitating the subsequent removal of the magnetic core.

[0021] Based on the above, the movable column moves upward to drive the magnetic core to be ejected and loosened from the forming cavity 31. When in use, it is avoided that the forming die 3 is driven to move upward. That is, when in use, after the upper movable plate 14 is controlled to move upward for a certain distance, a plurality of telescopic modules C142 arranged on the bottom side surface of the upper movable plate 14 are controlled to extend, so that the output ends of the telescopic modules C142 abut against the upper surface of the forming die 3, avoiding the forming die 3 being driven to move upward when ejecting the magnetic core.

[0022] The telescopic module A15, the telescopic module C142, and the telescopic module B13 are selected from telescopic cylinders or telescopic oil cylinders or telescopic motors; a handle 36 is arranged on the forming die 3.

[0023] In the description of this specification, the descriptions referring to terms such as "one embodiment", "example", "specific example", etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention.
