Make:

Socket 11, plug 15 and sole 1 can moldedly form.The unitary one-piece structure is a preferred structure.The method of molded plug 15 is technique known.

Preferably, socket element comprises socket wall, substrate, tongue, bar and button, and socket element forms so that the single-piece form is whole.But if tongue 33 and button 45 will form a single-piece with socket wall 35,43 and substrate 29 integral body, the manufacture method of mould that is used to make socket 11 so is just very complicated.

According to a further aspect of the present invention, socket 11 is molded with a shaft tunnel 27 at first, and this shaft tunnel is unimpeded always to its bottom from open top 13.Accompanying drawing 8A and 8B represent this initial socket.The shape of mould comprises the base sheet of an extension, and this thin slice is included in neighbouring part 51 and the remote section 53 around the axis hole of bottom, and remote section is connected to neighbouring part by a thin hinge fraction 55.Preferably, hinge fraction 55 thick about 0.2mm.Base part 51,53 and 55 remainders with socket element form so that the single-piece form is Unitarily molded.

In case this molding process is finished, just socket 11 is taken out from mould, and around substrate hinge fraction 55, with long distance base part 53 be folded back over contiguous base part 51 below, the substrate 29 of sealing socket shaft tunnel 27 thus.Then, socket 11 is placed on one and is used at the bottom of the molded shoe in 1 the mould, and this moment, socket aperture 13 was carried the bottom of being inverted the sole mould.Therefore, shaft tunnel 27 two ends can seal effectively, infiltrate shaft tunnel to avoid the resin material for sole of shoe, if infiltrated resin material in the shaft tunnel, so during use, these resin materials will hinder the insertion of plug.

Another problem that makes mobile material for sole of shoe not enter the socket shaft tunnel during molded is relevant with the hole 41 in the outer wall 43.Hole 41 allows button 45 and/or bar 47 to move through outer wall 43.Accompanying drawing 9 has shown a preferred embodiment, and the preferred embodiment provides a technical scheme that addresses this problem.Socket 11 is molded with a thin rupture diaphragm 59, and the about 0.1mm of thickness flushes with outer wall 43, this membrane closure hole 41.During at the bottom of the molded shoe, film 59 prevents that resin from passing hole 41 and infiltrating socket 11.

Furtherly, button 45 can so be shaped, and promptly can provide a big basal surface, and this basal surface can support membrane 59.Sole 1 is cast in a mould, wherein, can not infiltrate resin material in the whole socket shaft tunnel 27.In case it is molded good wherein to be embedded with the sole of socket 11 (each shoes preferably has about six sockets), and after from mould, taking out, just can carry out releasing operation, this releasing operation comprises a step of pressing each button 45, to destroy rupture diaphragm 59, because rupture diaphragm has realized that it prevents that resin from infiltrating the purposes of socket.
