Method and apparatus for controlling an injection mold having a first surface and a second surface includes an active material element configured to be disposed between the first surface and a second surface. The active material element may be configured to sense a force between the first surface and the second surface, and to generate corresponding sense signals. Transmission structure is coupled to the active material element and is configured to carry the sense signals. Preferably, an active material element actuator is also disposed between the first surface and a second surface, and is configured to provide an expansive force between the first surface and a second surface in accordance with the sense signals. The method and apparatus may be used to counter undesired deflection and/or misalignment in an injection mold.
L'invention concerne un procédé et un dispositif de commande d'un moule à injection comportant une première et une seconde surface, et qui comprend un élément de matière active conçu pour être placé entre les première et seconde surfaces. L'élément de matière active permet de détecter une force entre la première surface et la seconde surface, et de produire des signaux de détection correspondants. Une structure de transmission couplée à cet élément permet de transporter les signaux de détection. De préférence, un actionneur à élément de matière active, également placé entre la première surface et la seconde surface, permet de produire une force d'expansion entre celles-ci selon les signaux de détection. Le procédé et le dispositif permettent de contrer le fléchissement et/ou un défaut d'alignement dans un moule à injection.
