Abstract

The utility model provides a novel combined shoe mold, which is characterized in that ethylene vinyl acetate (EVA) molded in one step is combined with rubber to form a sole. The novel combined shoe mold comprises an upper mold, a middle frame, a middle plate and a bottom mold, wherein the rear side of the bottom mold is respectively provided with a ribbed plate along two sides of the lateral direction; each ribbed plate is provided with a '['-shaped guide slot; the rear side edge of the middle frame is provided with a pivot; two axial ends of the pivot are arranged in the '['-shaped guide slots in a sliding mode; the middle plate is arranged between the middle frame and the bottom mold; and the rear side edge of the middle frame is connected with the rear side edge of the upper mold by a hinge.

Description

A kind of novel combination type footwear mould

Technical field

The utility model relates to a kind of novel combination type footwear mould, and it is used for disposal molding EVA and building rubber compound sole.

Background technology

As everyone knows, the characteristics of EVA resin are to have good flexibility, elasticity as the rubber, under-50 ℃, still can have pliability preferably, the transparency and lustrous surface are good, chemical stability is good, anti-aging and anti-ozone intensity is good, and avirulence is good with the miscibility of filler, advantages such as painted and processing and forming is good, therefore people extensively are used to EVA to make sole, and with reference to figure 1, the EVA foaming molding mold comprises patrix 1 ' and counterdie 2 ', one side of described patrix 1 ' and counterdie 2 ' is along being connected through the hinge setting, and patrix 1 ' and counterdie 2 ' bonding part form the injection-expansion molded die cavity of suitable EVA of hollow.Same, rubber has firm solid, advantages such as wearability is strong, it is widely used in sole equally and makes, with reference to figure 2, a kind of mould of making double-colored rubber soles, it comprises patrix 3 ', plate 5 ' and bed die 6 ' in the center 4 ', one side of described bed die 6 ' is extended two chutes 8 ' along being provided with the true direction of hanging down, that side of center 4 ' the corresponding chute 8 ' is along being provided with pivot 9 ', the axial two ends of described pivot 9 ' can be located in the chute 8 ' respectively up or down, middle plate 5 ' is located between center 4 ' and the bed die 6 ', and center 4 ' is positioned between edge, pivot 9 ' the same side and the patrix 3 ' and is connected through the hinge.In moulding, die cavity in described between plate 5 ' and the bed die 6 ' is used for first color of moulding sole, on the sole of first color during moulding second color, remove in plate 5 ' make center 4 ', patrix 3 ' successively with bed die 6 ' matched moulds, inject second colorant in die cavity, make rubber soles with two kinds of colors.And in the time will making a kind of EVA of having and rubber combined sole, the common practice is earlier with after the end among the EVA and the difference moulding of the big end of rubber, manually both are bonded into one with glue, such way is that production efficiency is low on the one hand, another is because the precision of mould is not enough, the precision of product size is not enough, and product quality does not increase, and this is a weak point.

The utility model content

The purpose of this utility model provides the novel combination type footwear mould of a kind of disposal molding EVA and building rubber compound sole.

The technical scheme that the utility model adopted is such: a kind of novel combination type footwear mould, comprise patrix, center, middle plate and bed die, the rear side of described bed die is respectively equipped with a floor along both lateral sides, described floor is provided with " ㄈ " type gathering sill, described center rear side is along being provided with a pivot, described pivot shaft is slided to two ends and is located in described " ㄈ " type gathering sill, and middle plate is located between center and the bed die, and the center rear side is along being connected through the hinge with patrix rear side edge.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: the high position of the pivot of center is positioned at " ㄈ " type gathering sill, die cavity in this moment between plate and the bed die can the big end of injection moulding rubber, middle plate is removed in die sinking after being over, the low level of the pivot of center is positioned at " ㄈ " type gathering sill, make patrix, center, bed die matched moulds then, the end in cavity injection moulding EVA, middle plate adopts the high hardness aluminium alloy material, make EVA and the rubber can be at an in-mold molding, not only improved production efficiency, and the precision of product size is good.

Below in conjunction with accompanying drawing the utility model is specified for an embodiment.

Fig. 2 is the side view of known double-colored rubber boots mould;

Fig. 3 is the side view of the utility model embodiment;

The specific embodiment

With reference to figure 3, embodiment discloses a kind of novel combination type footwear mould, comprise patrix 1, center 2, middle plate 3 and bed die 4, the rear side of described bed die 4 is respectively equipped with a floor 5 along both lateral sides, described floor 5 is provided with " ㄈ " type gathering sill 51, described center 2 rear sides are along being provided with a pivot 6, slide and be located in described " ㄈ " type gathering sill 51 in described pivot 6 axial two ends, middle plate 3 is located between center 2 and the bed die 4, center 2 rear sides are along being connected by hinge 7 with patrix 1 rear side edge, and conveniently move along being provided with handle 31 described middle plate 3 front sides.

When using, with middle plate 3 and bed die 4 matched moulds, center 2 and patrix 1 close equally simultaneously, inject rubber in the die cavity between middle plate 3 and bed die 4, sulfidization molding makes the big end of rubber, in this process, the pivot 6 of middle plate 3 is positioned at " ㄈ " type gathering sill 51 high positions, die sinking then, plate 3 in removing makes pivot 6 be positioned at the low level of " ㄈ " type gathering sill 51, make center 2 direct and bed die 4 matched moulds, with patrix 1 downward matched moulds, inject the EVA material in the die cavity between patrix 1 and center 2 and bed die 4 again, foaming makes at the bottom of the modular shoe of EVA and building rubber compound.Plate 3 adopts the high hardness aluminium alloy material in described, guarantees the sole stay in grade that it at high temperature makes, the production efficiency height.

Claims

1. novel combination type footwear mould, it is characterized in that: comprise patrix, center, middle plate and bed die, the rear side of described bed die is respectively equipped with a floor along both lateral sides, described floor is provided with " ㄈ " type gathering sill, described center rear side is along being provided with a pivot, described pivot shaft is slided to two ends and is located in described " ㄈ " type gathering sill, and middle plate is located between center and the bed die, and the center rear side is along being connected through the hinge with patrix rear side edge.
