Abstract

Provided is an integrally injection-moulded middle sole including a hard plastic cement full middle sole, a hard plastic cement half middle sole, and a soft plastic cement forefoot middle sole. viscose glue fabrics and waist iron are put into an injection mould based on a needed middle sole mould, and then plastic cement is injected into the injection mould, after being cooled, the viscose glue fabrics are tightly glued on the external surface of a polypropylene injection-moulded middle sole to form the integrally injection-moulded middle sole provided with a viscose glue layer. According to the utility model, the integrally injection-moulded middle sole is simple in manufacturing and is integrally injection-moulded at the part where requires viscose glue subsequently, the viscose glue layer is formed to make the polypropylene injection-moulded middle sole have viscosity, so that the subsequent manufacturing of soles or finished shoes can be realized through a conventional gluing manner, and the problem that the polypropylene injection-moulded middle sole is not easy to glue can be better solved.

Description

The end in integrated injection molding footwear

Technical field

The utility model relates to a kind of footwear material, relates in particular to integrated injection molding footwear medium bottom shoes material.

Background technology

The end and with the end in these two kinds of footwear of waterproof platform in footwear traditionally,, be bonding by the cardboard type sheet material glue of multilayer, and mode connects the operations such as rear sizing polishing and completes, not only efficiency is low, be difficult to standardization, mechanization production, cannot guarantee the quality of product, enhance productivity.For above-mentioned shortcoming, be necessary to make improvements.

In order to reduce, to raise the efficiency people and attempting with the end in the better on-deformable polypropylene injection moulded shoes of toughness always, but because the smooth material of basal surface in polypropylene injection moulded shoes is difficult to viscose glue, be difficult to complete the making of product shoes in post-production operation. ?

Summary of the invention

The utility model provides the end in integrated injection molding footwear, makes the end in polypropylene injection moulded shoes well in post-production operation, complete the making of product shoes by glue.

For achieving the above object, the technical scheme that the utility model is taked is: the end in integrated injection molding footwear, comprise that hard plastic pitches the end in footwear entirely, the end in half fork and soft plastic half sole dual-density shoe, in injection mold, according to bottom die the inside in required footwear, put into viscose fabric, waist iron, inject plastic cement, cooling rear viscose fabric is closely pasted end outer surface in polypropylene injection moulded shoes, the end in the integrated injection molding footwear of formation adhesive-layer.

In described hard plastic half fork and soft plastic half sole dual-density shoe, the end, is one-body molded by mold injection.

Described viscose fabric is cloth, cardboard or the plastics of half opening or one chip.

Described half fork full fork upper surface and lower surface are also provided with one deck viscose fabric.

Described hard plastic half fork and soft plastic half sole top and bottom are provided with easy viscose fabric.

Described waist iron is located in hard plastic half fork.

Adopt the end in the utility model integrated injection molding footwear, make simple, one-body molded at the follow-up position that needs viscose glue, be formed with adhesive-layer, making in polypropylene injection moulded shoes the end have can viscosity, can by conventional adhesive means, carry out the manufacture of follow-up sole or product shoes, well solve the problem of end non cohesive gel in polypropylene injection moulded shoes.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described in further detail:

Fig. 1 is the structural representation at the end in half V shape footwear;

Fig. 2 is the structural representation at the end in full V shape footwear;

Fig. 3 is hard plastic half fork and soft plastic half sole structure schematic diagram.

In figure, each label respectively: 1 half sole, 2, waist iron, 3 half forks.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Embodiment 1:

With reference to the end in Fig. 1 the utility model integrated injection molding footwear, before injecting polypropylene, first half opening viscose fabric is divided in upper and lower two Pian Bancha 3 district's moulds, waist iron is placed on Ban Cha 3rd district, place and partly pitch 3 viscose fabrics through injecting after polypropylene injection molding shaping, the half opening viscose fabric of placing is closely pasted end outer surface in polypropylene injection moulded shoes, forms and partly pitches the end in footwear with the integrated injection molding of adhesive-layer.

Embodiment 2:

With reference to the end in Fig. 2 the utility model integrated injection molding footwear, before injecting polypropylene, first monolithic viscose fabric is divided into upper and lower two in mould, be placed in advance Ban Cha 3 district's moulds, waist iron is placed on Ban Cha 3rd district, monolithic viscose fabric is through injecting after polypropylene injection molding shaping, and the monolithic viscose fabric of placement is closely pasted end outer surface in polypropylene injection moulded shoes, forms and entirely pitches the end in footwear with the integrated injection molding of adhesive-layer.

Embodiment 3:

With reference to the end in Fig. 3 the utility model integrated injection molding footwear, hard plastic partly pitch 3 and soft plastic half sole 1 dual-density shoe in the end, in footwear, in bottom die, being provided with half sole 1 district He Bancha 3rd district distinguishes two by movable spacer, first viscose fabric is divided into upper and lower two in mould, waist iron is placed on Ban Cha 3rd district, hard plastic material injects in Ban Cha 3 district's footwear bottom die it is solidify to form, after solidifying, half fork 3 pulls open spacer, mould by front sole area is injected into soft plastic material in half sole 1 district's mould, with partly pitch 3 automatic bonding one, form hard plastic partly pitch 3 and soft plastic half sole 1 dual-density shoe in the end.

The foregoing is only preferential embodiment of the present utility model, not thereby limit the scope of patent of the present utility model, everyly utilize the essentially identical means of the utility model to realize the purpose of this utility model all to belong to protection domain of the present utility model.
