Abstract

The utility model discloses a kind of PVC foam co-extrusion hollow module, including：One body internal layer, is constituted using expanded material, for the ducted body of the hollow part provided with multiple insertions；One volume surrounding, co-extrusion is located at the outside of body internal layer, and this volume surrounding using one not expanded material constitute, the expanded material of the body internal layer of the present utility model is foamed polyvinyl chloride, and the not expanded material of this volume surrounding is not foamed polyvinyl chloride.Whereby, the utility model can effectively control cost, mitigate weight and solve the problem of expanded material its case hardness is undesirable and the unstable technical problem of expanded material color, make that the module engaged has suitable hardness and color reaches unanimously.

Description

PVC foam co-extrusion hollow module

Technical field

The utility model refers in particular to one kind and constitutes hollow knot using expanded material using body internal layer about a kind of module Structure, and in the PVC foam co-extrusion hollow module of this volume surrounding of its outside provided with not expanded material co-extrusion composition hard material.

Background technology

The existing door-plate by, in order to without using the material for cutting valve timber, all use and be constituted its entirety with expanded material Structure, but by the door-plate is made up of expanded material, so it is all solid and weight weight, not only difficult, and price Because it is calculated with weight it will be made to hold at high price, more cause its cost of transportation to improve, existing product is with the structure that foams Into door panel structure also result in its case hardness not enough, relative shortening on service life simultaneously has influence on it and uses scope, together When the existing product foaming door panel structure, more have influence on its structural color, cause its total unstable so that it is in practicality Property on have a greatly reduced quality, it is that those skilled in the art and consumer pole are intended to break through part that this, which is,.

Utility model content

To solve above-mentioned prior art weak point, the utility model main purpose is that providing a kind of PVC foam is total to Hollow module is squeezed, adopting expanded material using series of strata in body constitutes hollow structure, and in its outside provided with not expanded material co-extrusion This volume surrounding of hard material is constituted, to overcome difficulty of the prior art.

The utility model secondary objective is to provide a kind of PVC foam co-extrusion hollow module, and it effectively controls cost, subtracts Light weight, and solve the problem of expanded material its case hardness is undesirable and the unstable technical problem of expanded material color, Make that the module engaged has suitable hardness and color reaches unanimously.

The utility model further object is to provide a kind of PVC foam co-extrusion hollow module, and it effectively lifts its hardness, made With life-span and convenience.

The problem of the utility model is to be solved be：Existing door-plate, in order to without using the material for cutting valve timber, all use Its overall structure is constituted with expanded material, but by the door-plate is made up of expanded material, so it is all solid and weight Weight, not only difficult, and price all can make it hold at high price because it is calculated with weight, more cause its cost of transportation Improve, existing product also results in its case hardness not enough, relative shortening on service life with the door panel structure for the composition that foams And have influence on it and use scope, the door panel structure while existing product foams more has influence on its structural color, causes it entirely to tie Structure is unstable so that it has a greatly reduced quality in practicality.

In order to achieve the above object, the utility model provides a kind of PVC foam co-extrusion hollow module, including：

One body internal layer, is constituted using expanded material, for the ducted body of the hollow part provided with multiple insertions；And

One volume surrounding, co-extrusion be located at body internal layer outside, and this volume surrounding using one not expanded material constitute.

Wherein, the expanded material of the body internal layer is foamed polyvinyl chloride.

Wherein, the not expanded material of this volume surrounding is not foamed polyvinyl chloride.

The utility model adopts expanded material using body internal layer and constitutes hollow structure, and in its outside provided with not expanded material Co-extrusion constitutes this volume surrounding of hard material, and then reaches, and effectively controls cost, mitigate weight and solve expanded material its The problem of case hardness is undesirable and the unstable technical problem of expanded material color, make the module engaged have suitable hardness And color reaches unanimously, effectively lifts its hardness, service life and convenience.

Embodiment

The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art The utility model can be better understood from and can be practiced, but illustrated embodiment is limited not as to of the present utility model.

Refer to shown in Fig. 1, Fig. 2, Fig. 3, be three-dimensional exploded view of the present utility model, three-dimensional combination of the present utility model Figure, combination section of the present utility model, PVC foam co-extrusion hollow module of the present utility model are wrapped in a preferred embodiment A body internal layer 1, a volume surrounding 2 are included.

A foregoing body internal layer 1, is that expanded material constitutes and be provided with the ducted body that the hollow part 11 of multiple insertions is constituted, In the expanded material of the present embodiment body internal layer 1 be foamed polyvinyl chloride（POLY VINYL CHLORIDE, PVC）, but not The utility model is limited with this, it is except foregoing polyvinyl chloride（POLY VINYL CHLORIDE, PVC）Other materials in addition Material, all belongs to protection domain of the present utility model.

A foregoing volume surrounding 2, co-extrusion is outside the body internal layer 1, and this volume surrounding 2 is a not expanded material structure Into；The not expanded material of this volume surrounding 2 is a hard material, and the not expanded material of this volume surrounding 2 is in the present embodiment for not Foamed polyvinyl chloride（POLY VINYL CHLORIDE, PVC）, but the utility model not being limited with this, it gathers except foregoing Vinyl chloride（POLY VINYL CHLORIDE, PVC）Other materials in addition, all belongs to protection domain of the present utility model.

It can provide to be bonded with each other and can do door-plate, cupboard, shelf the utility model, can be assembled into for a plane, but simultaneously The utility model is not limited with this, its other article in addition to foregoing door-plate, cupboard, shelf all belongs to the utility model Protection domain.

Whereby, the utility model adopts expanded material using body internal layer 1 and constitutes hollow structure, and in its outside provided with not sending out Foam material co-extrusion constitutes this volume surrounding 2 of hard material, and then reaches, and effectively controls cost, mitigates weight and solves hair The problem of its case hardness of foam material is undesirable and the unstable technical problem of expanded material color, have the module engaged Suitable hardness and color reaches unanimously, effectively lifts its hardness, service life and convenience, meets progressive, practicality.

Embodiment described above is only the preferred embodiment to absolutely prove the utility model and being lifted, the utility model Protection domain not limited to this.Equivalent substitute or change that those skilled in the art are made on the basis of the utility model Change, within protection domain of the present utility model.Protection domain of the present utility model is defined by claims.
