    • In accordance with the teachings of the present invention, a mold comprises a nubbin positioned within the mold, and an actuator positioned within the mold to align the nubbin. The actuator may be implemented with a piezoelectric material, a magnetorestrictive material, an electrorestrictive material, etc. In one embodiment, the actuator is formed into a cylinder and placed around a nubbin in a mold. When the actuator receives a stimulus, the actuator constricts decreasing the size of the inner diameter. Decreasing the size of the inner diameter causes the actuator to constrict and align the nubbin along a centerline.
    • 根据本发明的教导,模具包括定位在模具内的模子,以及定位在模具内的致动器以对准模板。 致动器可以用压电材料,磁致伸缩材料,电致伸缩材料等来实现。在一个实施例中,致动器形成为圆柱体并且围绕模具中的凸块放置。 当执行器接收到刺激时,执行器会缩小内径的大小。 减小内径的尺寸会导致执行机构沿着中心线收缩和对准模板。
