TIRE CURING PRESS

摘要

A tire curing press for curing vulcanized tires includes an upper cavity part and a base that at least partially forms the lower cavity part. A movable platen is supported by the base that supports a tire mold section received within the upper cavity part. In various examples, an outer riser column is secured to the base and extends vertically upwards from the base to support the upper cavity part, a multi-height lock ring is disposed upon the base and is configured to interface with an annular flange of the upper cavity part via a bayonet connection, first and second cylinders are configured to apply a substantially equal squeeze pressure to the movable platen to thereby establish a final tire curing pressure within the press cavity, and/or a lock plate is carried by the upper cavity part and includes a locking surface for selective engagement with an abutment shoulder.

主权项

1. A tire curing press, comprising:
a press cavity for curing vulcanized tires, comprising an upper cavity part and a lower cavity part; a base comprising a main body that at least partially forms the lower cavity part, and an extended support portion that is integral with the main body and extends a distance outwards from the lower cavity part; a movable platen supported by the base and vertically movable relative to the base, the movable platen configured to support a tire mold section that is received within the upper cavity part during a tire curing operation; an outer riser column secured to the extended support portion of the base and extending vertically upwards from the base, the upper cavity part being supported by the outer riser column for vertical movement relative to the lower cavity part; and a main support frame configured to support the base upon a support surface, the main support frame comprising a plurality of discrete support columns fixed to said support surface.
