HYDRAULIC/PNEUMATIC FOOTWEAR MOLDING DEVICE

Abstract

A hydraulic/pneumatic footwear molding device includes a foot shaped elastic capsule filling of fluid, pressurized by a pressurizing unit sealed and connected at the rear end of the elastic capsule. The elastic capsule is placed in the inner cavity of a lattice frame. When the liquid is used as the internal fluid medium of the elastic capsule and the pressurizing unit is in the form of an electric heating device capable of moving up and down, not only the pressurization of the liquid can be realized by the up-down movement of pressurizing unit to expand the elastic capsule, but also the heat molding can be achieved by heating the liquid as an electric iron.

DETAILED DESCRIPTION

A hydraulic/pneumatic (hydraulic type or air pressure type) footwear molding device includes a foot shaped elastic capsule 1 filling of fluid, pressurized by a pressurizing unit 3 sealed and connected at the rear end of the elastic capsule.

The said pressurizing unit 3 is sealed with elastic capsule 1 and placed together in the inner cavity of the lattice frame with large area of gaps.

A rotatable pressing locking mechanism 4 is set on the pressurizing unit 3, and the pressing locking mechanism 4 cooperates with the self-locking mechanism 5 with multi-level positioning points on the lattice frame 2 to implement the function of pressurization, pressure-locking and decompression to the elastic capsule.

The said lattice frame (hard materials such as metal or plastic) used as a constraint holder for the elastic capsule makes the elastic capsule expand through the large area of gaps.

The said fluid is liquid fluid, and the said pressurizing unit is an electric heating device capable of moving up and down to heat the elastic capsule which improves the heating effect as electric iron.

The said fluid is gaseous fluid, and the said pressurizing unit is an inflator to inflate the elastic capsule.

Because the footwear has different types of high legs and low legs, so a covering part to limit the partial deformation of the elastic capsule is set on the partial surface of the lattice frame to selectively restrict the expansion area and direction of the elastic capsule, so that the pressure and the heat in accordance with the type of footwear only work in the required parts.

Take the example of liquid fluid. When in use, the users press the pressurizing unit 3 with hands squeezing downwards to the elastic capsule 1, then make the pressing locking mechanism 4 cooperate with the positioning self-locking mechanism 5, and the liquid in the elastic capsule 1 after pressure expands into all directions in the inner cavity of the footwear and closely fits the footwear through the large area of gaps of the lattice frame 2. Thus when the pressurizing unit 3 equipped with electric heating device is energized to transfer the heat and pressure to all the parts of the inner cavity of the footwear through the liquid, regardless of the changes of styles and sizes of footwear, the molding effect will be perfect.
