Detailed description of the invention
The embodiment of the present invention carries out gradient amendment by using pressure balance principle to mould mo(u)ld top half, major part direction ratio microcephaly direction is made to exceed 0.25mm, because the power that press is downward is level, thus make the compacting downward multiple pressure 0.25mm of magnetic core major part out, make base thickness consistent; By ejection resistance principle to female die of die demoulding height and angle modification, after making magnetic core take the type of making by force, ejection resistance drops to minimum, according to magnetic core compacting thickness, stay 1.5mm patrix inserting thickness size, remainder is all revised as demoulding size, and under the prerequisite not affecting outward appearance, angle is the bigger the better, draft angle is minimum at 15 degree of resistances, and does not affect outward appearance.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be described in detail the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of protection of the invention.
Shown in ginseng Fig. 1, for the magnetic core of electromagnetic oven, comprise the main part 1 being positioned at horizontal plane, this main part has relative inner edge 11 and outside 12 and the first side 13 be connected between inner edge 11 and outside 12 and second side 14, the width of inner edge 11 is less than the width of outside 12, the shape of first side 13 and second side 14 is arc, and the arc of first side 13 and second side 14 has identical recessed direction.Distance between inner edge 11 and outside 12 is 83.7mm.
Further, the shape of inner edge 11 and outside 12 is the arc arranged with one heart.Inner edge 11 and outside 12 protrude out the first flange 2 of arc and the second flange 3, first flange 2 and the second flange 3 respectively perpendicular to main part 1 and are positioned at the same side of main part 1.The 3rd flange the 4, three flange 4 and the first flange 2, second flange 3 that are also formed with arc between first flange 2 and the second flange 3 are arranged with one heart.Distance between 3rd flange 4 and the first flange 2 is less than the distance between the 3rd flange 4 and the second flange 3.
Further, the recessed notch 31 being formed with rectangle in the middle part of the second flange 3.
In this technical scheme, the magnetic core for electromagnetic oven of the present invention effectively reduces electromagnetic radiation, improves the efficiency of heating surface of electromagnetic oven; Strong and weak according to Distribution of Magnetic Field; The fan-shaped combination not etc. of design magnetic stripe inner edge and outside two width, thus it is even to realize Distribution of Magnetic Field;
Shown in ginseng Fig. 2 and Fig. 3, the edge that first side 13 and second side 14 are positioned at flange side is formed with the first anticracking inclined-plane 131.
Further, the first anticracking inclined-plane 131 is 15 ° with the angle of vertical direction.
Further, the ratio between the height on the first anticracking inclined-plane 131 and main part 1 thickness is 14:19.
Further, the edge of first side 13 and away from flange side, second side 14 is formed with the second anticracking inclined-plane 132.Preferably, the ratio between the height on the second anticracking inclined-plane 132 and main part 1 thickness is 1/228.
Shown in ginseng Fig. 4, ES magnetic core mould, comprises the die 5 and punch 6 that match, and one end that the corresponding inner edge of punch 5 is compared in the one end outside punch 6 is corresponding protrudes out a=0.25mm downwards.
In this technical scheme, by using pressure balance principle, gradient (0.15 degree) amendment is carried out to mould mo(u)ld top half, major part direction ratio microcephaly direction is made to exceed 0.25mm, because the power that press is downward is level, thus make the compacting downward multiple pressure 0.25mm of magnetic core major part out, make base thickness consistent.
