When the device is used specifically, a person skilled in the art will make the smelting raw material flow into the first feeding pipe 120 and the second feeding pipe 310 through the injection port 110, and at the same time, the smelting raw material uniformly flows into the first branch pipe 130 and the second branch pipe 320, and then the first blanking pipe 131 and the second blanking pipe 321 are used in cooperation, the smelting raw material is synchronously injection-molded on the upper side surface and the lower side surface of the bidirectional compression molding plate 300, after the permanent magnet injection is completed, the water inlet valve 220 is opened and the water outlet valve 520 is closed, the cooling water flows into the first water inlet pipe 230 through the water inlet 210, and is uniformly delivered into the first water dividing pipe 240, so as to inject the cooling water between the upper mold groove 610 and the lower mold groove 710, so that the cooling water can cool the permanent magnet between the upper mold shell 620 and the lower mold shell 720, and at the same time, the communicating pipes 250 and 330 are used in cooperation, the cooling water flows into the second water inlet pipe 340 through the communication pipe 330, and is uniformly delivered into the second water distribution pipe 341, so that the cooling water is injected between the upper mold cavity 610 and the lower mold cavity 710 on the lower side, and the permanent magnet between the upper mold shell 620 and the lower mold shell 720 on the lower side is cooled, and then the water outlet valve 520 is opened and the cooling water is continuously injected, so that the cooling effect between the upper mold shell 620 and the lower mold shell 720 on the upper side and the lower side is accelerated, after the cooling is completed, the water inlet valve 220 is closed and the water outlet valve 520 is opened, so that the cooling water flows out from the water outlet 510, the first air pressure push rod 360 and the second air pressure push rod 430 are started, so that the upper mold body 100, the bidirectional die plate 300 and the lower mold body 400 are sequentially separated, and a worker uses a tool to take the finished permanent magnet between the upper mold shell 620 and the.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

While the invention has been described above with reference to an embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the various features of the embodiments disclosed herein may be used in any combination, provided that there is no structural conflict, and the combinations are not exhaustively described in this specification merely for the sake of brevity and conservation of resources. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
