Embodiment Construction

[0096] refer to Figure 1a , Figure 1b and Figure 1c, will illustrate a prior art molding system. These figures schematically show a prior art mold 2 and a last 30, both in cross-sectional view, that can be used for direct injection molding of footwear according to the prior art. The mould 2 may be made of metal (eg aluminium, eg CNC machined), and as Figure 1a and Figure 1b As shown, a first side mold 4, a second side mold 8 and a bottom mold 14 may be included, arranged in such a way that the mold 2 can be opened and closed, for example by the first side mold 4 and the second side mold 8 It is possible to move in the horizontal direction as indicated by arrows A, B, and in the vertical direction as indicated by arrow C by means of the bottom mold 14 being arranged.

[0097] Furthermore, if Figure 1a As shown, upper 32 may be placed on last 30 and may move in various directions with upper 32, including downward relative to mold 2 as indicated by arrow D. FIG. It w...

Abstract

A footwear moulding system for the direct injection production of footwear, the footwear moulding system comprising:-a support mould (21) comprising at least one inner mould support,-a last (30),-an inner mould (22) being elastic,-an injection channel (40) for injecting the last (30) into the support mould (21), and-an injection channel (40) for injecting the last (30) into the inner mould (22). And wherein the inner mold (22) comprises an inner mold outer surface (76) configured to be supported by the inner mold support, and the inner mold support comprises at least one support side mold (26, 28) and a support bottom mold (24). Furthermore, the invention relates to a direct injection footwear production method for footwear by using such a molding system.

Description

technical field [0001] The present invention relates to a footwear molding system for direct injection production of footwear and a direct injection production method for footwear molding. Background technique [0002] It is well known to manufacture footwear by means of direct injection moulding of the sole to the upper. [0003] The direct injection process (DIP) has advantages in many ways because the resulting footwear can have both flexibility and strength. [0004] One challenge with this direct-injection process is that this method creates waste of sole material that is manually trimmed after each injection. [0005] GB1226957A describes a footwear moulding system for moulding a sole unit to a shoe. The footwear moulding system comprises a sole module provided with a groove in the form of a sole unit, the groove being bounded by a peripheral wall. In this prior art embodiment, a sheet-like portion of elastically deformable silicone rubber extends through the groove...
