Abstract
(EN)
A die-casting forming mold for vulcanized rubber boots, comprising: a combined cylinder mold (24, 25, 26) that is provided with an inner cavity corresponding to a cylinder of a rubber boot; a shoe last mold (27) that has a separating element and that is provided with a main body basically corresponding to the shape of the cylinder of the rubber boot, as well as two or more separating elements provided on the main body, the shoe last mold (27) being suitable for being installed in the inner cavity of the cylinder mold (24, 25, 26) so as to form a die-casting forming cavity between a wall of the inner cavity of the cylinder mold (24, 25, 26) and an outer surface of the shoe last mold (27), and the die-cast forming cavity being divided by the shoe last mold (27) and the cylinder mold (24, 25, 26) into two or more parts; and a rubber injection deflector plate suitable for being mounted at a top portion of the cylinder mold (24, 25, 26) so as to guide the injection of an unvulcanized mixed rubber material, which comprises a plate body, wherein the plate body is provided thereon with a rubber injection hole suitable for being connected to an external injection head so as to inject the unvulcanized mixed rubber material, as well as a ring-shaped rubber injection channel used for introducing the externally-injected unvulcanized mixed rubber material into the die-casting forming cavity in ring-shaped distribution.
