Abstract

The utility model belongs to the technical field of shoemaking, and discloses a double-color sole mold, which comprises an upper mold and a bottom mold, wherein the lower surface of the upper mold is provided with a mold core, and the bottom mold is provided with a mold cavity matched with the mold core; a color separation groove hermetically matched with the mold core is arranged in the mold cavity; the middle plate is used for raising the upper die when the upper die and the bottom die are closed; and after the middle plate is padded between the upper die and the bottom die and the dies are closed, a gap with the same thickness as the middle plate is formed between the die core and the color separation groove. The light weight of the whole die can be realized, particularly, the middle plate is adopted to heighten the upper die, so that the color bars of one color can be processed through the color separation grooves under the condition that the middle plate is not padded, then the upper die is lifted to enable the gap between the die core and the color separation grooves under the condition that the middle plate is padded, and thus, the raw material of the other color and the pre-formed color bars can be hot-pressed together to form the bicolor sole under the hot-pressing condition.

Description

Double-color sole mold

Technical Field

The utility model relates to a shoemaking technical field, especially a double-colored sole mould.

Background

The manufacture of the bicolor sole is mostly divided into two directions in the field: in the first direction, after one color is manufactured in one mold, the other mold is turned to perform hot press molding with the other color; and in the second direction, an integrated die is adopted, one color is manufactured between the upper die and the middle plate, the other color is manufactured between the lower die and the middle plate, and then the middle plate is removed to carry out hot press molding on the two colors between the upper die and the lower die.

The direction one can refer to: the applicant's quanzhou concerted mold limited filed in 2015 of utility model application zl201520947373.x, which discloses a two-color cold mold sole mold, comprising a first mold set and a second mold set; the first module consists of a first upper template, a first lower template and a first articulated shaft, wherein the first end of the first upper template is rotationally connected with the first end of the first lower template through the first articulated shaft, the first upper template is provided with a first mold core and a first filling hole communicated with the first mold core, and the first lower template is provided with a first mold cavity corresponding to the first mold core; the second module comprises a second upper template, a second lower template and a second hinged shaft, the first end of the second upper template is rotatably connected with the first end of the second lower template through the second hinged shaft, a second mold core and an annular groove are arranged on the second upper template, a second mold cavity corresponding to the second mold core in position is arranged on the second lower template, and a convex column abutted against the second mold core is arranged in the second mold cavity.

The second direction can be referred to specifically as follows: applicant Dongguan city stands victory mould limited company in 2014's the utility model patent application ZL201420025827.3 that proposes, it discloses a precision sole mould of two-color sole of a mould shaping, comprising a base plate, go up the mould, lower mould and a medium plate that can take out, the bottom plate is assembled in last mould, the medium plate is assembled between last mould and lower mould, go up and offer the first die cavity that is used for the upper sole that the type has first colour between mould and the medium plate, offer the second die cavity that is used for the bottom sole that the type has the second colour between medium plate and the lower mould, the matched die surface of medium plate top surface and the matched die surface shape phase-match of bottom surface, go up mould and lower mould compound die after taking the medium plate out, upper sole and bottom sole compound become integrative.

The problem with the first direction is that an excessive number of molds are required; the problem with the second direction is that in which the plate is used to form two molding cavities, its thickness is very thick as shown in the drawing; in either direction, the problems of complicated structure and excessive weight exist.

The technical problem that this application will solve is: how to make double-colored sole in a mould and need to guarantee lightweight.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a double-colored sole mould, this mould can realize the lightweight of whole mould, particularly, it adopts the medium plate to go up the mould bed hedgehopping, can process the colour bar of a colour through separating the look ditch under the condition of not filling up the medium plate like this, then under the condition that fills up the medium plate, go up the mould and raise and make the mold core and separate the look ditch between gapped, just so can become double-colored sole with the raw materials of another colour and preformed colour bar hot pressing together under the hot pressing condition.

The specific scheme is as follows: a double-color sole mold comprises an upper mold and a bottom mold, wherein a mold core is arranged on the lower surface of the upper mold, and a mold cavity matched with the mold core is arranged on the bottom mold; a color separation groove hermetically matched with the mold core is arranged in the mold cavity; the middle plate is used for raising the upper die when the upper die and the bottom die are closed;

and after the middle plate is padded between the upper die and the bottom die and the dies are closed, a gap with the same thickness as the middle plate is formed between the die core and the color separation groove.

In the above-mentioned double-colored sole mould, the thickness of well board is 0.8mm, and the designer can set for well board thickness according to actual conditions: 0.5mm-3 mm.

In the double-color sole mold, the middle plate is a plate body matched with the edge shape of the upper mold, and the center of the middle plate is provided with an opening part for the mold core to pass through.

The beneficial effects of the utility model reside in that:

the utility model discloses a medium plate will go up the mould bed hedgehopping, can process the colour bar of a colour through separating the look ditch under the condition of not filling up the medium plate like this, then under the condition that has the medium plate filling up, go up the mould and raise and make the mold core and separate the look ditch between gapped, just so can become the double-colored sole with the raw materials of another colour and the colour bar hot-pressing of preforming together under the hot pressing condition.

The thickness of the plate in the die can be as low as less than 1mm, and the weight and the thickness of the die can not be obviously increased.
