Abstract
A mold closing assembly having two platen supporting bodies or turrets mounted on a base to pivot in a generally horizontal plane about two vertical pivot axes. At least one platen reciprocates linearly to clamp the mold sections together, and a tie bar extends above the two turrets between the pivot points. Preferably the mold closing assembly has a modular construction.
Claims28
A mold closing assembly for supporting and selectively closing two mold sections, comprising:
- a base;
- a first platen support body mounted on said base and having a first platen thereon;
- a second platen support body mounted on said base and having a second platen thereon;
- at least one of said platen support bodies having a vertical pivot axis, said one platen support body mounted to selectively pivot relative to said base about said vertical pivot axis between an aligned position in which said platens are aligned for closing and an unaligned position in which said platens are pivotally unaligned for access;
- means for selectively linearly advancing and retracting one of said platens toward the other of said platens when said one platen support body is in said aligned position;
- and
- means for selectively pivoting said one platen support body between said aligned position and said unaligned position in a generally horizontal plane.
A mold closing assembly for supporting and selectively closing two mold sections, comprising:
- a support bed;
- two platen support bodies laterally spaced and mounted on said bed, each said platen support body having a platen thereon;
- means for linearly reciprocating one of said platens with respect to the other of said platens;
- means for horizontally pivoting at least one of said platen support bodies;
- and
- a tie bar extending above said platen support bodies and coupling said platen support bodies above said platens.
The mold closing assembly for supporting and selectively closing two mold sections, comprising:
- a support base having two laterally spaced turret supporting regions thereon;
- two platen supporting turrets pivotally mounted on said support base at said turret mounting regions, each said turret having a platen thereon;
- at least one of said turrets having a platen advancement cylinder thereon, said platen advancement cylinder operably coupled to one of said platens for the linear reciprocation thereof, and a guide rod slidably coupling said one platen with said one turret;
- a pivot post received through each of said turrets, said pivot posts secured to said support base, and said turrets each having means for pivoting said turret about said pivot post;
- and
- a tie bar extending above said turrets between said pivot posts and coupling said turrets.
