具体实施方式

图1是本发明的磁力片的主视图，图2是本发明的磁力片的俯视图，图3是本发明的磁力片的立体图，图4是本发明的磁力片的磁性结构的示意图，图5是本发明的磁力片的磁性结构的主视图，图6是本发明的磁力片的塞体的主视图，请参见图1至图3所示，示出了一种较佳实施例的磁力片，包括：框型结构1，在本实施例中，框型结构1是呈正方形的环状结构；在其他实施例中，框型结构也可以呈长方形、圆形、三角形、菱形、平行四边形、多边形等其他平面形状；在更多的实施例中，框型结构1还可以是锥形、圆柱形、圆台形、金字塔形等其他空间立体形状。框型结构1上开设有若干通孔2，沿框型结构1的外缘设有若干磁性结构3，磁性结构3能够允许若干同种或不同种的框型结构1之间方便地可拆卸连接。框型结构1与若干磁性结构3一体成型，从而避免磁性结构3在长时间使用过程中损坏或脱落。
此外，作为一种较佳的实施例，每一磁性结构3均包括：钢管31、设于钢管31内的磁铁32、以及设于钢管31两端的塞体33。在另一种较佳的实施例中，钢管31也可以采用其他材质的管状结构，例如塑料管等代替。磁铁32优选为圆柱体。磁性结构3的结构允许磁铁32能够自由地在钢管31的内部沿轴向转动，从而在与其他磁力片相互磁吸时能够自适应地调整磁极的方向。通过塞体33对钢管的密封，使得框型结构1在一体成型的过程中，成型 材料不会与磁铁32相接触，从而避免对磁铁32的固定。
进一步，作为一种较佳的实施例，框型结构1包括：呈环状的外框部11、设置在外框部11内的呈环状的内框部12、以及连接外框部11和内框部12的连接部13，其中，若干磁性结构3位于外框部11内。优选的，外框部11的纵截面可以是圆形或椭圆形，内框部12的纵截面可以是圆形或椭圆形，连接部13的纵截面可以为矩形，其中，外框部11的厚度和内框部12的厚度均大于连接部13的厚度，使得外框部11和内框部12之间形成环状的凹槽15，凹槽15以连接部13的表面为底面、以外框部11的侧面和内框部12的侧面为侧壁。
更进一步，作为一种较佳的实施例，框型结构还包括：若干加强筋14，若干加强筋14设置于连接部13上，若干加强筋14的两端分别与外框部11和内框部12相链接。具体的，若干加强筋14设置在凹槽15内。优选的，每一磁性结构3处均设有一加强筋14。在另一种较佳的实施例中，在外框部11和内框部12之间设有更多的加强筋14，以调节磁力片的整体强度。若干加强筋14之间形成有第一槽141，第一槽141由模具上的位于磁性结构3侧面的第一凸起形成，当磁性结构3放入模具中时，磁性结构3的侧面抵于第一凸起，使得磁性结构3的径向能够受到模具的限位。
再进一步，作为一种较佳的实施例，外框部11靠近内框部12的一侧设有第二槽111，每一磁性结构3的两端均设有两第二槽111，第二槽111由模具上的位于磁性结构3两端的第二凸起形成，当磁性结构3放入模具中时，磁性结构3的两端抵于第二凸起，使磁性结构3的轴向能够受到模具的限位。
下面说明磁力片一体成型的方法：
步骤S1：提供上模和下模，分别在上模和下模上形成若干第一凸起，粉饼在上模和下模上形成若干第二凸起，其中，若干第一凸起位于磁性结构3的预定位置的两端，若干第二凸起位于磁性结构3的预定位置的侧面。
步骤S2：将若干磁性结构3分别放入预定位置内，合模铸造。
在步骤S1中，第一凸起和第二凸起均与上模或下模固定连接。
在步骤S2中，优选的，第二凸起可以是固定在上模或下模上的铁杆。
在步骤S2中，磁性结构3的两端分别抵于第一凸起，磁性结构3的侧面抵于第二凸起，从而在铸造时对磁性结构3进行定位。
以上所述仅为本发明较佳的实施例，并非因此限制本发明的实施方式及保护范围。
本发明在上述基础上还具有如下实施方式：
本发明的进一步实施例中，请继续参见图1至图6所示，塞体33为一体式结构，塞体33依次包括：塞入钢管31内的呈圆柱状的塞入部331、用于密封钢管31的呈圆台状的密封部332、以及与框型结构1相连接的呈圆柱状的连接部333。当框型结构1在被一体成型时，框型结构1的部分材料包裹于连接部333外，更进一步地，框型结构1的部分材料也可以包裹密封部332的一部分，从而限制磁性结构3沿磁力片外缘方向上的移动，同时也限制磁性结构3在磁力片径向方向上的移动。
本发明的进一步实施例中，当框型结构1在被一体成型时，框型结构1的部分材料也可以包裹于钢管31的侧面，从而进一步地磁性结构3在磁力片径向方向上的移动。
本发明的进一步实施例中，塞入部331的外径大于连接部333的外径；密封部332的较大的底面的外径大于塞入部331的外径，且密封部332的较小的底面的外径大于连接部333的外径。
本发明的进一步实施例中，若干通孔2均沿框型结构1的厚度方向开设，若干通孔2沿框型结构1的外缘一周均匀分布。在本实施例中，由于框型结构1的形状为正方形，因此通孔2较佳地布置于框型结构1的角部，在框型结构1为其他形状时，通孔2可以根据实际需要布置。
