Abstract
A system in which gravitation and inertial effects on platen verticality and sagging are compensated by an anti-tilt actuator (). A hydraulic actuator () secured beneath the platen is either set to offset only gravitationally-related sagging of the mold half () by providing a compensating upward force (relative to a stable clamp base), or otherwise its upward force can be dynamically adjusted also to compensate for swaying or tilting of the mold-platen assembly caused by stroke cylinder () operation and related inertia/momentum effects. Preferably, a level sensor () measures and communicates a degree of horizontalness/verticality of the platen () to a machine controller () which, in turn, generates a control signal () to cause variation in cylinder pressure in the anti-tilt actuator (), thereby achieving substantially continuous alignment between the mold halves () and reduced component wear.
