Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in the figure, cylinder permanent magnet mould of the present utility model, comprise supporting upper mold core 1 and lower mold core 2, to be located at bottom lower mold core 2 and surrounding level protrude lower mold core 2 base plate 3, to be respectively placed on base plate about 3 protruding end 3.1 and inwall be close to upper mold core 1 and lower mold core about 2 end face buckle 4, to be placed in before and after base plate 3 on protruding end 3.2 and inwall is close to the baffle plate 5 of upper mold core 1 and lower mold core 2 front/rear end respectively.For preventing the assembling being shifted and being convenient to each parts when suppressing, described base plate 3 is fixedly connected with bottom lower mold core 2, and the length that the protruding end, front and back 3.2 of described base plate 3 is protruded than left and right protruding end 3.1 is long.In the present embodiment, described being fixedly connected with is realized by the mode of welding, and can certainly be realized by integral structure, namely lower mold core and base plate are the entirety that same raw material processes simultaneously.
The lower surface of described upper mold core 1 and the upper surface of lower mold core 2 are provided with multiple die cavity 6 for forming cylinder permanent magnet, and described die cavity 6 to extend and fore-and-aft direction along lower mold core 2 is arranged side by side along the left and right directions of lower mold core 2.Described die cavity is made up of the arc groove be separately positioned on upper mold core lower surface and lower mold core upper surface, and two arc grooves form a manhole, and this manhole is just die cavity, plastic go out cylinder permanent magnet.
The front and back end of described buckle 4 is respectively equipped with inwall and baffle plate 5 outer wall and is close to rib 4.1 with fastening baffle plate 5.Just by baffle plate fastening, effectively can being prevented the displacement of baffle plate when suppressing, making the whole mould assembled form an entirety and can not scatter by the rib of buckle.
As the preferred version of the present embodiment, the lower surface of described upper mold core 1 and the upper surface of lower mold core 2 are provided with three die cavities 6 for forming cylinder permanent magnet, and these three die cavities 6 are evenly arranged side by side along the fore-and-aft direction of lower mold core 2.
During compacting, open upper mold core, Powdered rare earth permanent-magnetic material is placed in die cavity, subsequently upper mold core is built, the mould assembled is placed on press, now base plate is placed on the workbench of press, start press, oil cylinder for presses drives depression bar to run downwards and pushes down upper mold core, upper mold core descending pressed powder shape rare earth permanent-magnetic material, now the electromagnet of press left and right sides clamps two buckles respectively, until depression bar continuation is descending press required cylinder permanent magnet completely.
Cylinder permanent magnet mould of the present utility model can press high-quality cylinder permanent magnet, and the cylinder permanent magnet shape molded is well-balanced, and inside is very fine and close.Cylinder permanent magnet forming die structure of the present utility model is simple in addition, and parts are few, easy to assembly, and cost is also low.
