At present, in mould, be mainly to utilize the exhaust sheet to carry out exhaust.Refer to shown in Fig. 1, in Fig. 1, the exhaust structure of prior art comprises some exhaust sheets 10, these some exhaust sheets 10 are linked together by alignment pin 20, the first row air drain 11 that vertically to be provided with the degree of depth on this exhaust sheet 10 be 0.3mm and laterally be provided with the second row air drain 12 that the degree of depth is 0.02mm.When injection molding product, gas can be discharged by first row air drain 11 and second row air drain 12.Yet exhaust sheet 10 process in this exhaust structure are loaded down with trivial details, add the first line of needs in man-hour and cut, then grind, then join mould with mould; And this exhaust structure takes up room larger in male model; Exhaust effect is general in addition.

In view of this, in fact be necessary to provide a kind of novel exhaust structure, this novel exhaust structure can solve that above-mentioned processing is loaded down with trivial details, large and the general problem of exhaust effect take up room.

[summary of the invention]

Therefore, the purpose of this utility model is to provide a kind of exhaust structure, and this exhaust structure can solve that above-mentioned processing is loaded down with trivial details, the large and general problem of exhaust effect takes up room.

In order to achieve the above object, exhaust structure of the present utility model, be applied in mould, and this exhaust structure comprises:

The first exhaust sheet, some the first terminals that it has the first side wall and vertically extends this first side wall, described two adjacent the first terminals form accommodation section separately, and vertically offer respectively some first row air drains on this first side wall and this some the first terminals;

The second exhaust sheet, some the second terminals that it has the second sidewall and vertically extends this second sidewall, this second terminal correspondence is arranged in described accommodation section, vertically offers some second row air drains on this second sidewall.

Preferably, described first row air drain and second row air drain have bottom surface and extend the two sides of bottom surface, and the degree of depth of described each first row air drain and second row air drain is the degree of depth that bottom surface is extended in side, and the degree of depth of each first row air drain and second row air drain is identical.

Preferably, the degree of depth of described each first row air drain and second row air drain is 0.05mm.

Preferably, described the first exhaust sheet and the second exhaust sheet cut processes by line.

Preferably, on described the first exhaust sheet and the second exhaust sheet, be respectively equipped with screw, this screw coordinates screw that described exhaust structure is fixed in mould.

Preferably, the two ends of described the first side wall and the second sidewall are respectively equipped with chamfering.

Compared to prior art, exhaust structure of the present utility model is by the first exhaust sheet and the combination of the second exhaust sheet, the first exhaust sheet in this kind of exhaust structure and the processing of the second exhaust sheet are fairly simple, without secondary operations, and the exhaust structure after combination takes up room smaller, reduced Mould Machining and joined the mould time, air discharge duct is all contained in exhaust structure surrounding and the centre after the combination in addition, so the exhaust effect of this exhaust structure is very good.

[specific embodiment]

Please jointly consult shown in Fig. 2, Fig. 3 and Fig. 4, combination schematic diagram, Fig. 3 that wherein Fig. 2 has illustrated the utility model exhaust structure have illustrated the decomposing schematic representation of the utility model exhaust structure and the partial enlarged drawing that Fig. 4 has illustrated Fig. 2.

Exhaust structure of the present utility model, be applied in injection mold, and in the present embodiment, this exhaust structure comprises:

The first exhaust sheet 100, six the first terminals 120 that it has the first side wall 110 and vertically extends this first side wall 110, described two adjacent the first terminals 120 form accommodation section 130 separately, therefore this accommodation section 130 is five, and vertically offer respectively some first row air drains 140 on this first side wall 110 and this six the first terminals 110, wherein, the two sides that these some first row air drains 140 have bottom surface and extend bottom surface, the degree of depth of described each first row air drain 140 is the degree of depth that bottom surface is extended in side, the degree of depth of each first row air drain 140 is identical, in the present embodiment, the degree of depth of described each first row air drain 140 is 0.05mm,
