The invention relates to a method for manufacturing a shoe part by injection molding a material into a mold where an insert is placed. The insert comprises at least two separable insert parts, an upper insert part and a lower insert part, providing an injection channel in the region of the separation area between the two parts. The insert is placed in the chamber and the injection material is injected through a sprue channel in the mold into the injection channel and into a cavity, whereby the shoe part is formed. The mold is opened after the injection material has cured and the insert is separated into the upper and lower insert parts, thereby exposing the cured material in the injection channel.

Embodiments herein disclose a primary sole part (10) having a foot facing surface (11) and a ground facing surface (12). The primary sole part (10) comprises a plurality of through-going holes (14), wherein the plurality of through-going holes extends in a vertical direction from the foot facing surface (11) to the ground facing surface (12). The foot facing surface (11) is configured to receive an injected sole material for attaching the primary sole part to a ground facing surface (12) of an upper (1).

A footwear injection mould for Direct Injection moulding of footwear parts, where the mould comprises: a first mould cavity defining a first footwear part, a second mould cavity defining a second footwear part, a first side frame defining at least a part of a first side of the first and second mould cavities, a second side frame defining at least a part of a second side of the first and second mould cavities, and a bottom frame defining at least a part of the first and second mould cavities, where the first and/or the second side frame define(s) at least a part of a first injection channel which is in fluid communication with the first mould cavity and the second mould cavity.

A footwear moulding system for direct injection production of footwear, said footwear moulding system comprising a supporting mould (21), a last (30), an in-mould (22), and an injection channel (40),
wherein the supporting mould (21) comprises at least an in-mould support.

The in-mould (22) is elastomeric and the in-mould (22) comprises an in-mould outer surface (76) configured to be supported by said in-mould support.

The in-mould support comprises at least one support side mould (26, 28) and a support bottom mould (24).

Further, the invention relates to a direct injection footwear production method for footwear by use of such a moulding system.

A system of manufacturing equipment including molds for a direct injection production of footwear. The system includes a design facility that provides a design. A mold manufacturing facility manufactures a mold for the design for molding a sole of the footwear. A last manufacturing facility manufactures a last of the design. A footwear manufacturing facility manufactures footwear according to the design. The last corresponds to the footwear design and the mold corresponds to the footwear design. The mold is a basic direct injection mold and at least partly channels injection material to a mold cavity and further accommodates direct injection mold inserts. Mold descriptive data of the mold inserts is communicated to the footwear manufacturing facility to manufacture the mold inserts, or the mold inserts are manufactured at the mold manufacturing facility based on the mold descriptive data and transported to the footwear manufacturing facility.

A molding system for direct injection manufacturing of footwear. The molding system includes a mold cavity for receiving injection material for molding a sole part of the footwear. The system further includes a plurality of basic direct injection molds, each of which is attachable to injection molding equipment, and a plurality of sets of direct injection mold inserts, each set of direct injection mold inserts being configured to define at least part of an inner surface of the mold cavity when inserted in one of the plurality of basic direct injection molds. At least two of the plurality of basic direct injection molds differ from each other in size, corresponding to different ranges of sole part sizes.

A sole assembly for footwear includes a base plate and at least two sole pods disposed adjacent one another but spaced apart by a gap. The sole pods define respective apertures that form an integral truss in each. The apertures can be aligned and parallel with one another and/or a longitudinal axis of the base plate and sole assembly. The truss system of the respective pods can independently deform to provide underfoot cushioning, but also can conform around and absorb underfoot terrain features. A method of manufacturing the sole assembly can include forming the sole pods adjacent one another in a planar configuration, rotating each of the sole pods to an upright configuration and joining those sole pods to one another but separating them from one another with a gap.

The present invention provides a rubber injection guide plate for guiding injection of unvulcanized mixed rubber, comprising a plate body, wherein the plate body is provided with: a rubber injection port to be connected with an external injection head to inject unvulcanized mixed rubber; and an annular rubber injection channel for leading the externally injected unvulcanized mixed rubber out in an annular distribution manner.

The present invention provides a transfer molding mold for a vulcanized rubber boot, comprising: a combined tube mold, having an inner cavity corresponding to a tube of the rubber boot a last mold with partition elements, having a main body substantially corresponding to the tube of the rubber boot in shape, and two or more partition elements disposed on the main body, wherein the last mold is suitable for installation into the inner cavity of the tube mold to form a transfer molding cavity between the wall of the inner cavity of the tube mold and the outer surface of the last mold, and the transfer molding cavity is partitioned into two or more parts by the last mold and the tube mold; and a rubber injection guide plate suitable for installation to the top of the tube mold to guide injection of unvulcanized mixed rubber, comprising a plate body, wherein the plate body is provided with: a rubber injection port to be connected with an external injection head to inject the unvulcanized mixed rubber; and an annular rubber injection channel for introducing the externally injected unvulcanized mixed rubber into the transfer molding cavity in an annular distribution manner.
