摘要： The molding of plastic articles particularly footwear in which two mold components are capable of being closed along a parting or separating line to provide at least in part a molding cavity and which components include recesses for constituting a supply duct for the cavity when the components are closed and at least one injection port leading from one of the recesses into the cavity at a location other than the parting or separating line.

摘要： A method of injection molding a multilayer sole of elastomers onto an upper of a shoe by means of a multi-part mold which includes a last carrying the upper of the shoe. Side cheeks are movable relative to each other and a sole plate is displaceable relative to the last. The sole plate provided with a sprue channel, extending in the longitudinal direction of the sole plate, and further provided with a plurality of junction channels distributed along the length of the sprue channel and terminating in a hollow space of the mold. The method comprises the steps of injecting elastomer material for a first sole layer into the hollow space of the mold upon enlarging the hollow space by displacement of the sole plate, without filling up completely the hollow space. The elastomers are distributed over the length of the sole plate in dependence upon the number of the junction channels chosen. The cross-sections of the junction channels and the injection speed relative to each other, are adjusted such, that the distribution takes place in quantities of said elastomer material required for the formation of the toe end, the heel end and the center part of that sole layer, respectively. The elastomer material is pressed onto the upper of the shoe by slow displacement of the sole plate towards the last. A sole layer is formed by slow build-up of pressure in the hollow space of the mold, and by injecting thereafter again elastomer material into the enlarged hollow space of said mold, a second sole layer is formed by renewed slow displacement of the sole plate towards the last.

摘要： An article of footwear having a two-color rubber sole construction, and a method and apparatus for manufacturing the article. The sole construction includes a midsole-foxing component having foxing surrounding and engaging an outsole component which is vulcanized to the midsole-foxing component. The rubber used for the midsole-foxing component has a higher modulus than the rubber used for the outsole component. The higher modulus rubber is injected into a mold cavity having a column considerably greater than the volume of the injected rubber and a movable soleplate spreads the injection rubber against the underside of a lasted upper. The soleplate has a peripheral shoulder which determines the lower end and inner surface of the foxing. The lower modulus rubber is also injected into a mold cavity of considerably greater volume. The soleplate is again advanced toward the lasted upper to spread the outsole rubber against the midsole rubber to be vulcanized thereto.

摘要： AN INJECTION MOLDING APPARATUS HAVING A PLURALITY OF MOLDING UNITS EMBOYDING A SOLE MOLD MOVABLE FROM A FIRST POSITION DEFINING A FIRST MOLDING CAVITY TO A SECOND POSITION DEFINING A SECOND MOLDING CAVITY. MECHANISM IS PROVIDED FOR BRINGING SUCESSIVE MOLDING UNITS INTO COMMUNCATION WITH A FIRST INJECTOR AND THEREAFTER WITH A SECOND INJECTOR, WITH THE FIRST INJECTOR INTRODUCING A MOLDING MATERIAL INTO THE FIRST MOLDING CAVITY THROUGH A SINGLE CHANNEL IN THE SOLE MOLD AND THE SECOND INJECTOR INTRODUCING A SECOND MOLDING MATERIAL INTO THE SECOND

MOLDING CAVITY THROUGH THE SAME CHANNEL. THE SOLE MOLD IS MOVED FROM ITS FIRST TO ITS SECOND POSITION DURING TRAVEL OF THE MOLDING UNITS FROM THE FIRST INJECTOR TO THE SECOND INJECTOR.
