    摘要: 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.

    摘要: A check valve for a screw is provided. The check valve includes a retainer tip, operable to be attached to a distal end of a screw shaft, the retainer tip defining at least one melt channel. A first ring is coaxially mounted to and rotationally-coupled with the retainer tip. A second ring is coaxially and slidably mounted to the retainer tip, and is operable to rotate relative to the retainer tip. The second ring is operable to reversibly move between an open position which permits melt to flow through the check valve and a closed position which prevents backflow of the melt.

    摘要: A platen (50) for a molding machine includes an intermediate support structure (20) between two planar walls (16, 18) having ribs (40) arranged at a non-normal angle β to a first wall (18). The ribs (40) couple forces from the first wall (18) to the second wall (16) in such a way that bending of the second wall (16) is resisted. This adds to the rigidity of the second wall (16) and hence the platen (50), adding to flatness of the arrangement. Gussets (42) may be provided extending between the ribs (40) and the intermediate support structure (20). This has the effect of surrounding and supporting an injection bore (14) and further adding to the coupling of forces to the edge portions of the second wall (16) to resist forces acting to bend the wall.

    摘要: A injection unit (10) of an injection system, including a shooting pot (12) having a shooting pot head (13) at one end, defining a melt chamber (14) therein; a melt inlet channel (16) for laterally bringing melt into the melt chamber (14); a plunger (26) arranged in the melt chamber (14), the plunger (26) being linearly moveable from a retracted position into an extended position, so as to force melt accumulated in the melt chamber (14) through a melt outlet channel (20) arranged in said shooting pot head (13) into an injection mold; an annular melt passage (28) provided between the melt chamber (14) and the plunger (26), for allowing the melt to flow from the melt inlet channel (16) to an outlet end (18) of the melt chamber (14); and a melt distribution channel (30) for distributing the melt from the melt inlet channel (16) to the annular melt passage (28). An important aspect of the invention is that the melt distribution channel (30) be distal from the melt inlet channel (16) so as to ensure even distribution of the melt to the annular melt passage (28).
