Abstract

The utility model discloses a kind of parian co-extrusion foaming lines extrusion die, including the die body, rebound, supporting plate, mouth mould and the chill that are sequentially connected, it is characterized in, the mouth mould includes first mould and second mouthful of mould, the first mould is located at described second mouthful between mould and chill, and 0.25 0.35mm is turned down in lowest point position in the co-extrusion surface of second mouthful of mould.The co-extrusion surface of second mouthful of mould is in convex-concave shelving shape, 0.30mm is preferably turned down in lowest point position, when product goes out chill, the lowest point position on the co-extrusion surface will be soon than other positions, as its position is turned down, product gap after making chill out is uniform, it is consistent to reach, and intensity is higher.The utility model efficiently solves the problems, such as that the product co-extrusion gap of lines co-extruding mould production in the past is uneven, improves product strength, it is ensured that product quality.

Description

A kind of parian co-extrusion foaming lines extrusion die

【Technical field】

The utility model is related to co-extruding mould technical field, and more particularly to a kind of parian co-extrusion foaming lines extrude mould Tool.

【Background technology】

The co-extrusion face gap of the mouth mould of lines co-extruding mould was the same, its 0.2mm less than the gap in not co-extrusion face in the past, But, when chill is gone out, the speed of its lowest point will cause product co-extrusion than other positions to product soon Gap uneven, insufficient strength, easily affect product quality.

【Utility model content】

In view of this, for overcoming the deficiencies in the prior art, the utility model provides a kind of parian co-extrusion foaming lines Extrusion die, turns down the lowest point co-extrusion face gap of mouth mould, efficiently solves the problems, such as that product goes out chill post gap uneven, Ensure that product quality.

For achieving the above object, the technical solution of the utility model is as follows：

A kind of parian co-extrusion foaming lines extrusion die, including be sequentially connected die body, rebound, supporting plate, mouth Mould and chill, are characterized in, the mouth mould includes first mould and second mouthful of mould, and the first mould is located at second mouthful of mould Between chill, 0.25-0.35mm is turned down in lowest point position in the co-extrusion surface of second mouthful of mould.

Preferably, the co-extrusion surface of second mouthful of mould is in convex-concave shelving shape, 0.30mm is turned down in lowest point position, producing When product go out chill, the lowest point position on the co-extrusion surface as its position is turned down, will be made soon than other positions Chill out after product gap uniform, reach consistent, intensity is higher.

The beneficial effects of the utility model are that structure improvement is ingenious, by turning down a mouthful gap for mould co-extrusion surface lowest point, So that the effect of its motion speed when product goes out chill is offset, the co-extrusion gap uniformity of final products is reached, it is ensured that The higher intensity of product and quality.

【Description of the drawings】

In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below will be to embodiment Or accompanying drawing to be used is briefly described needed for description of the prior art, it should be apparent that, drawings in the following description are only It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise for not paying creative work Under, other accompanying drawings can also be obtained according to these accompanying drawings.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the structural representation of second mouthful of mould in Fig. 1.

Fig. 3 is the magnifying state schematic diagram on the co-extrusion surface of second mouthful of mould in Fig. 2.

【Specific embodiment】

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of the utility model protection.

With reference to Fig. 1 and Fig. 2, a kind of parian co-extrusion foaming lines extrusion die, including the die body 1, mistake being sequentially connected Cab apron 2,3, second mouthful of mould 4 of supporting plate, first mould 5 and chill 6, first mould 5 be located at second mouthful of mould 4 and chill 6 it Between.

As shown in Figure 2 and Figure 3, co-extrusion surface 41 is provided with the die cavity of second mouthful of mould 4, and co-extrusion surface 41 is in convex-concave shelving shape, It is 1.5mm that location A at lowest point B location is than other turns down 41 gap of co-extrusion surface of 0.30mm, i.e. location A, and B position 41 gap of co-extrusion surface in the range of putting is 1.2mm, so when product goes out chill, the lowest point B on the co-extrusion surface 41 Position than location A speed at other will soon, but as its position is turned down, so make from chill 6 out after product Gap uniformity, reach consistent, it is ensured that the higher intensity of product and quality.

Preferred embodiment of the present utility model is the foregoing is only, not in order to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent substitution and improvement that is made etc., should be included in the utility model Protection domain within.
