SUMMERY OF THE UTILITY MODEL

Based on this, the utility model aims to provide an effectively improve fretwork sole mould of sole gas permeability for the sole produces different deformation according to the pressurized difference, improves user's use experience degree through letting the bleeder vent be in different states.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: a hollowed-out sole mold comprises an upper mold base and a lower mold base, wherein the upper mold base and the lower mold base are arranged in an enclosing mode to form a shoe mold cavity, the shoe mold cavity is used for forming a sole, a plurality of forming columns are arranged below the upper mold base at intervals along the length direction of the shoe mold cavity, and the forming columns extend towards the direction of the lower mold base; the upper end face of the lower die base is provided with a plurality of butt-joint columns in the shoe mold cavity in an inward protruding mode, and the lower end portions of the forming columns are attached to the upper end portions of the butt-joint columns.

In one embodiment, the forming column and the butt column are of a truncated cone configuration.

In one embodiment, one side of the lower end part of the forming column is provided with a butt joint groove, one side of the upper end of the butt joint column is provided with a butt joint lug, and the butt joint lug is matched with the butt joint groove.

To sum up, the hollow sole mold of the utility model has the advantages that the forming column is convexly arranged at the lower end part of the upper mold base, the butt-joint column is convexly arranged on the lower mold base in a matching way, the pore diameter of the vent hole for forming the sole is smaller than the pore diameter of the upper end part and the lower end part of the vent hole by butting the lower end part of the forming column and the upper end part of the butt-joint column, when the sole is pressed by the foot of a user, the part of the sole, which is pressed by the foot, is deformed at the vent hole, and the vent hole is extruded by the sole and blocked; the ventilation holes at other parts of the sole with lower pressure of the foot keep the ventilation state unchanged, thereby achieving the effect of ventilation of the sole.

Detailed Description

For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.

As shown in fig. 1 to 3, the utility model relates to a fretwork sole mould includes upper die base 10 and die holder 20, upper die base 10 encloses with die holder 20 and establishes and form shoe mold cavity 30, shoe mold cavity 30 is used for shaping sole 40, upper die base 10 below is provided with a plurality of shaping posts 11 along shoe mold cavity 30 length direction interval, shaping post 11 extends towards die holder 20 direction.

The upper end surface of the lower die holder 20 is provided with a plurality of butt-jointed columns 21 protruding in the shoe mold cavity 30, the forming columns 11 are attached to the butt-jointed columns 21 so as to form air holes 41 in the sole 40, the forming columns 11 and the butt-jointed columns 21 are of a cone frustum structure, specifically, the lower end parts of the forming columns 11 are attached to the upper end parts of the butt-jointed columns 21, butt-jointed grooves 111 are formed in one side of the lower end parts of the forming columns 11, butt-jointed bumps 211 are arranged on one side of the upper ends of the butt-jointed columns 21 and are matched with the butt-jointed grooves 111 so as to form air holes 411 in the middle parts of the air holes 41 in the sole 40, and the aperture of each air hole 411 is far smaller than the aperture of the cross sections.

The utility model discloses during the specific use, at first dock upper die base 10 and lower die base 20, make the shaping post 11 and docking post 21 laminate the setting respectively, recycle the injection molding machine and pour into the plastic raw materials into shaping sole 40 in the shoe mold die cavity 30, make shaping post 11 and docking post 21 docking portion shaping out holistic bleeder vent 41, docking slot 111 and docking lug 211 docking portion shaping air vent 411 of sole 40, because air vent 41 upper end to air vent 411 department form the structure of narrow from top to bottom, cooperation air vent 411 department to the tip of bleeder vent 41 form the structure of narrow from top to bottom, when sole 40 receives the pressure of user's foot, sole 40 receives the great position of foot pressure to produce deformation in air vent 411, air vent 411 receives sole 40 extrusion and blocks up, thereby reach the supporting effect of entity sole 40; the ventilation holes 411 of other parts of the sole 40 with lower pressure of the foot keep the ventilation state unchanged, so that the ventilation effect of the sole 40 is achieved; when the foot moves continuously, the force-bearing position of the sole 40 changes continuously, and the vent holes 411 are blocked at the sole 40 part with higher pressure, so that the supporting effect of the solid sole 40 is generated, and the pressure resistance of the breathable sole 40 is effectively improved.
