Abstract:
A method of and apparatus for injection molding solid steel-banded industrial rubber tires wherein a steel band is inserted in the bottom mold member cavity when the top mold member is in open position. Bite ring and knockout member components are contained in mold member cavity recesses. Closing movement of the mold members to mated position seals the bite ring and knockout member components against the steel bank and mold member recess surfaces to prevent leakage of injected rubber compound from the cavity during injection and curing. The mold has an internal wedge member which expands a split ring against the steel band when the mold is closed to prevent band distortion from pressure existing when the mold is injected and the rubber is cured therein to form the tire tread portion which is bonded to the steel band during curing. Mold components knock the cured tire out of the top mold member upon opening the mold. The rubber compound is injected into the mold cavity under pressure at the curing temperature of the compound and this temperature is maintained during curing.
