Assignee:

David Wolfe Design, Inc - Akron OH

International Classification:

B29C 33/10

US Classification:

425472, 249141, 425425, 425812

Abstract:

A method of venting a rotational mold at a predetermined condition by actuating an actuating venting assembly pierces the shell of the molded article and introduces a passageway to relieve pressure during the molding cycle. The actuating venting assembly enables a tactical methodology for venting such molds.

International Classification:

B29C 3340
B29C 4514

US Classification:

264155

Abstract:

Making a tire mold by spraying molten atomized metal on a model to form a metal shell and then reinforcing the shell with a resin backing to form a mold segment for the tire mold. Modular shoe container assemblies have replaceable backing members for making different size molds and flat plate spacers for providing different thicknesses of the mold segment. In one embodiment a slide block is used for one side of the cavity whereby a sole plate is eliminated.

International Classification:

B29C 3500

US Classification:

425117

Abstract:

Molds for injection molding tire components have controlled temperature passages leading to a manifold surrounding each mold cavity. The manifold is positioned to minimize weld lines in the injected tire component. In addition, a narrow gate opening between the manifold and mold cavity provides an elevated temperature of the injected material for decreasing the curing time of the tire component in the mold. Blade members may support and position tire components such as bead apex assemblies in the mold. These tire components may be unloaded by an unloader ring in communication with a source of vacuum for pulling the tire component out of the mold.
