Abstract

The utility model provides a plastic sucking, foaming, die cutting composite die, which is formed by sealing and connecting an upper module and a lower module of cast aluminum, wherein the composite die is formed by compositing a skin plastic sucking, a P U foaming and an outline die cutting dies on the same die, and the dies are respectively formed by an upper module and a lower module which can be sealed and engaged. The plastic sucking, foaming, die cutting composite die has compact structure, which reduces the used equipment, saves use space, saves labor cost, and greatly improves the production efficiency of products.

Description

A kind of plastic uptake, foaming, die-cut composite die

Technical field

The utility model relates to a kind of plastic uptake, foaming, die-cut composite die, is specifically related to plastic uptake, foaming, die-cut composite die that a kind of function that how secondary mould is realized is integrated into the manufacturing automotive upholstery of finishing in the secondary mould.

Background technology

The product by EVA epidermis+PU foaming in the automotive upholstery is divided into EVA epidermis plastics sucking moulding, PU foaming, die-cut three steps of profile usually at present.Operation equipment production sites many, that take many, that drop into operating personnel many, that use are many, production efficiency is low but this exists, and because of repeatedly locating, cause product quality to be difficult to control.

The utility model content

Main task of the present utility model is to provide a kind of plastic uptake, foaming, die-cut composite die, specifically is plastic uptake, foaming, die-cut composite die that a kind of function that how secondary mould is realized is integrated into the manufacturing automotive upholstery of finishing in the secondary mould.

For solving the problems of the technologies described above, a kind of plastic uptake of the utility model, foaming, die-cut compound mould, be tightly connected by the upper and lower mould of cast aluminium and constitute, its innovative point is: described composite die is compounded on the mould and is formed by epidermis plastic uptake, PU foaming, die-cut three moulds of profile, and described this mould is made of the upper die and lower die of salable cooperation respectively.

Be provided with heater in the die body of described patrix, on patrix, have the foaming charging aperture, and be set into edge of a knife shape with hard material at the peripheral profile of patrix.

Described heater is: the some equidistant stainless steel heating pipes that cast in the patrix die body.

Described counterdie is the cavity of sealing, and profile is provided with and vacuumizes aperture, and is provided with vacuum interface on die body.

The advantage of above structure is: compact conformation of the present utility model, reduced the equipment that uses, and saved the space of using, save cost of labor, and improved production efficiency of products greatly.

Description of drawings

Fig. 2 is a partial enlarged drawing of the present utility model;

Fig. 3 is a partial enlarged drawing of the present utility model.

The specific embodiment

The specific embodiment of the present utility model is done the explanation in a nearly step below in conjunction with accompanying drawing.

The utility model is to adopt EVA epidermis plastics sucking moulding, PU foaming, die-cut three moulds of profile to be integrated on the mould and to realize.

Concrete structure as shown in Figure 1, described mould is sealed and matched by upper and lower mould 1,2 and connects and composes, and the material of upper and lower mould 1,2 is the cast aluminium material.

As shown in Figure 2, described patrix 1 is provided with heater, and its heater is the some equidistant stainless steel heating pipes 3 that cast in patrix 1 die body.This heater is connected with the thermal water source, can realize the circulation heating; In addition, on patrix, also have foaming charging aperture 4, enter die cavity for foamed material; In order to make the product that processes on this mould, realize cutting, the peripheral profile of this patrix 1 inlayed with hard material 5 and be processed into edge of a knife shape.It more than is the structure of patrix.

The structure of counterdie as shown in Figure 3, described counterdie 2 is the cavity-like of sealing, the aperture 6 that its profile band vacuumizes, and be provided with vacuum interface 7 link to each other with vaccum-pumping equipment on the die body of counterdie 2 is so that satisfy the needs that mould vacuumizes.

During moulding, this mould just becomes one EVA epidermis plastics sucking moulding, PU foaming, die-cut three functions of profile, concrete action is as follows: counterdie 2 vacuumizes by vaccum-pumping equipment earlier, the moulding of plastic uptake epidermis, patrix 1 closes down then, be tightly connected with counterdie 2, start the heater heating, realize EVA epidermis plastics sucking moulding; The epidermis that the hard material 5 of edge of a knife shape is good with plastic uptake then cuts off, and realizes that profile is die-cut, and also plays the effect of envelope material simultaneously; Inject the PU foamed materials from the charging aperture 4 of patrix at last and foam, die sinking behind the foaming and setting is directly taken out product and is removed waste material and promptly realize the PU foaming.

Claims

1, a kind of plastic uptake, foaming, die-cut compound mould, be tightly connected by the upper and lower mould of cast aluminium and constitute, it is characterized in that: described composite die is compounded on the mould and is formed by epidermis plastic uptake, PU foaming, die-cut three moulds of profile, and described this mould is made of the upper die and lower die of salable cooperation respectively.

2, a kind of plastic uptake according to claim 1, foaming, die-cut compound mould is characterized in that: be provided with heater in the die body of described patrix, have the foaming charging aperture on patrix, and be set into edge of a knife shape at the peripheral profile of patrix with hard material.

3, a kind of plastic uptake according to claim 1, foaming, die-cut compound mould, it is characterized in that: described heater is: the some equidistant stainless steel heating pipes that cast in the patrix die body.

4, a kind of plastic uptake according to claim 1, foaming, die-cut compound mould is characterized in that: described counterdie is the cavity of sealing, and profile is provided with and vacuumizes aperture, and at die body vacuum interface is arranged.
