Abstract

The utility model provides a PU (polyurethane) dual-density shoe sole mold. A middle frame is arranged between a bottom mold and an upper mold; the bottom mold is connected with the middle frame and the middle frame is connected with the upper mold respectively through hinges; a structure matched with the bottom of a bottom shape is arranged on the bottom mold; a bulge is arranged on a foot palm part of a side mold; a bottom frame matched with the bottom shape is arranged on the middle frame; after the side mold, the middle frame and the bottom mold are buckled, the bulge on the foot palm part of the side mold is tightly matched with the foot palm part of the bottom mold, and a clearance formed by other parts is matched with the thickness of the bottom shape; the upper mold is matched with the bottom frame on the middle frame; after the upper mold, the middle frame and the bottom mold are buckled, a formed clearance is matched with the bottom shape. According to the PU dual-density shoe sole mold, a PU material which is soft and comfortable is placed at the foot palm position and is integrally combined with another PU material which is high in hardness and abrasion resistance, so that the comfortableness and the appearance of a shoe sole are greatly improved; the shoe sole produced by the mold has the advantages of portability, comfortableness and attractive appearance.

Description

PU dual-density shoe bottom die

Technical field

The utility model belongs to technical field of shoe making, is specifically related to a kind of shoe-making die.

Background technology

At present, the annual footwear industry output in the world reaches 15,000,000,000 pairs, mainly concentrate on Asian countries, there are rubber, PU, PVC, MD, TPR, TPU, EVA etc. in China as the main material of the maximum production in the whole world and exported country's production sole, wearability because of PU sole in numerous kinds sole is good, quality is light, advantages such as outward appearance is beautiful and become numerous consumers' first-selection, but because the softness of PU sole is general, many footwear manufacturer attempts producing dual-density sole, further to improve elasticity and the comfortableness of sole.During conventional PU dual-density sole is manufactured, people normally with single density PU do the large end, dual density PU does the middle end, and the large end of single density is once pressed to suitcase dress again, often that people are worn is light comfortable for this sole, outward appearance is beautiful, so be deeply subject to people's favor.

But, in recent years, people are for comfort level and the higher requirement of aesthetic appearance of dual density PU sole, each producer of shoe industry all did repeatedly and attempted, but do not have real substantial effect, yet traditional single density PU does the large end, dual density PU does the manufacture craft at the middle end and has the following disadvantages:

1. sole support force is bad;

2. single density, the two-layer sole quality that causes of dual density PU are partially heavy;

3. single density PU does the large end, dual density PU does the middle end, affects sole outward appearance.

Summary of the invention

The purpose of this utility model is to provide a kind of PU dual-density shoe bottom die, to solve the problems of the technologies described above.

Mould described in the utility model, is mainly comprised of bed die, patrix, and the technical scheme that technical solution problem adopts is, between bed die and patrix, center is set, and bed die and center, center and patrix are connected through the hinge respectively; Side form is set on bed die, and bed die and side form are connected through the hinge; The buckle that handle is set respectively and cooperatively interacts on bed die, center, patrix and side form; The structure matching with die bed bottom is set on bed die, side form sole position arranges projection, the underframe matching with die bed is set on center, after side form, center and bed die fasten, the projection at side form sole position and bed die sole position fit tightly, and the gap at other positions and die bed thickness match; Underframe on patrix and center cooperatively interacts, and after patrix, center and bed die fasten, gap and the die bed of formation match.

During use, first fasten center and bed die, then pour into PU material I, cover side form, and locking snap device, the projection at side form sole position expects that by PU I is squeezed to other positions outside sole, then heats and carries out one step foaming after foaming successfully, the sole position of die bed is groove shape, and other positions are still normal structure; Open side form, at sole position perfusion PU material II, cover patrix, after locking snap device, heat and carry out second time of foaming, obtain complete sole after foaming successfully.

The die bed of mentioning in technical scheme designs the structure of the sole of intend producing, and comprises the structure, lines of its form, size, thickness, bottom etc.

PU dual-density shoe bottom die described in the utility model is owing to relatively soft comfortable PU material being made in to position, the centre of the palm and integrally combining with another kind of hardness, the higher another kind of PU material of wearability, the comfortableness of sole and the property seen are greatly improved, and the sole that adopts this mould to produce has light, comfortable, rakish advantage.The sole that adopts this mould to produce can also be done and press suitcase dress not affect the outward appearance of whole sole, and has greatly alleviated the light sense that sole weight has further improved sole.

Accompanying drawing explanation

Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated:

Fig. 1 is structural representation of the present utility model;

1 patrix, 2 centers, 3 side forms, 4 bed dies, 5 hinges, 6 projections, 7 buckles, 8 handles, 9 underframes in figure.

The specific embodiment

As shown in Figure 1, between bed die 4 and patrix 1, center 2 is set, bed die 4 is connected by hinge 5 respectively with patrix 1 with center 2, center 2; Side form 3 is set on bed die 4, and bed die 4 is connected by hinge 5 with side form 3; The buckle 7 that handle 8 is set respectively and cooperatively interacts on bed die 4, center 2, patrix 1 and side form 3; The structure matching with sole die bed bottom is set on bed die 4, side form 3 sole positions arrange projection 6, the underframe 9 matching with die bed is set on center 2, after side form 3, center 2 fasten with bed die 4, projection 6 and the bed die 4 sole positions at side form 3 sole positions fit tightly, and the gap at other positions and sole die bed thickness match; Patrix 1 cooperatively interacts with the underframe 9 on center 2, and after patrix 1, center 2 fasten with bed die 4, the gap of formation and sole die bed match.

During use, first fasten center 2 and bed die 4, then pour into PU material I, cover side form 3, and lock buckle 7, the projection 6 at side form 3 sole positions expects that by PU I is squeezed to other positions outside sole, then heat and carry out one step foaming, after foaming successfully, the sole position of die bed is groove shape, and other positions are still normal structure; Open side form 3, at sole position perfusion PU material II, cover patrix 1, after locking buckle 7, heat and carry out second time of foaming, obtain complete sole after foaming successfully.
