Abstract: Disclosed herein, amongst other things, are structure and steps for positioning a first mold part of a mold on a mold mounting face in an injection molding machine. In particular, the structure and steps may include a positioner that is configured to connect the first mold part to part of the injection molding machine, wherein the positioner is adjustable to position the first mold part across the mold mounting face.

Abstract: A system in which gravitation and inertial effects on platen verticality and sagging are compensated by an anti-tilt actuator (68, 70). A hydraulic actuator (68, 70) secured beneath the platen is either set to offset only gravitationally-related sagging of the mold half (60, 62) by providing a compensating upward force (relative to a stable clamp base 80), 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 (98) operation and related inertia/momentum effects. Preferably, a level sensor (94) measures and communicates a degree of horizontalness/verticality of the platen (48, 50) to a machine controller (88) which, in turn, generates a control signal (87) to cause variation in cylinder pressure in the anti-tilt actuator (68, 70), thereby achieving substantially continuous alignment between the mold halves (60, 62) and reduced component wear.

Abstract: FIG. 3 illustrates a system in which gravitation and inertial effects on platen verticality and sagging are compensated by an anti-tilt actuator (68, 70). Specifically, and particularly with the location of a heavy weight mold half (60, 62) on a platen (48, 50), platen tilting (58) and front face sagging occurs as a consequence of at least one of: i) the overhanging mass of the mold half; ii) inertia effects caused by stroking of the platen. A hydraulic actuator (68, 70) secured beneath the platen is either set to offset only gravitationally-related sagging of the mold half (60, 62) by providing a compensating upward force (relative to a stable clamp base 80), 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 (98) operation and related inertia/momentum effects.
