Description
[technical field]
This utility model relates to a kind of two-way vacuum extractor.
[background technology]
Existing by between yarn and yarn when pressing, in order to more closely combine, need to carry out in advance evacuation, make the pressing between yarn and yarn be in vacuum state.But due to existing, air is arranged the cleanest, containing air in product, causing combining between yarn and yarn not tight, processing effect is bad.
[summary of the invention]
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of patch yarn is tightly combined, effective two-way vacuum extractor.
For solving above-mentioned technical problem, this utility model have employed following technical proposals:
A kind of two-way vacuum extractor, it is characterized in that including lower mold body 1 and upper die body 2, between lower mold body 1 and upper die body 2, it is provided with one can close the cavity 3 carrying out evacuation, lower mold body 1 is provided with the lower evacuation passageway 4 communicated with cavity 3, upper die body 2 is provided with and can need the film body 7 of the gauze of pressing, when upper die body 2 is provided with evacuation, film body is close to the upper evacuation passageway 5 of upper die body inner surface.
Two-way vacuum extractor as above, it is characterised in that be provided with in described cavity 3 and can place the platform 6 needing pressing gauze.
Two-way vacuum extractor as above, it is characterised in that also include the driving structure down pressed by upper die body 2.
Compared with prior art, this utility model has the advantage that
After this case puts product into cavity, utilizing upper evacuation passageway to carry out evacuation afterwards, make film body be close to the bottom of upper die body, the lower evacuation passageway of recycling carries out the evacuation of cavity afterwards, go up evacuation passageway vacuum breaker afterwards, now film body is by the vacuum attraction of cavity, is close to the surface of product, makes air emptying inside product, product is compressed by upper die body more afterwards, making more closely to combine between yarn and yarn, both ensure that the intensity of product, the outward appearance making again product is more good-looking.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model.
[detailed description of the invention]
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings and this utility model is described further by embodiment.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As shown in the figure, a kind of two-way vacuum extractor, including lower mold body 1 and upper die body 2, between lower mold body 1 and upper die body 2, it is provided with one can close the cavity 3 carrying out evacuation, lower mold body 1 is provided with the lower evacuation passageway 4 communicated with cavity 3, upper die body 2 is provided with and can need the film body 7 of the gauze of pressing, when upper die body 2 is provided with evacuation, film body is close to the upper evacuation passageway 5 of upper die body inner surface.In use, after putting product into cavity, upper evacuation passageway is utilized to carry out evacuation afterwards, film body is made to be close to the bottom of upper die body, the lower evacuation passageway of recycling carries out the evacuation of cavity afterwards, go up evacuation passageway vacuum breaker afterwards, now film body is by the vacuum attraction of cavity, it is close to the surface of product, making air emptying inside product, product is compressed by upper die body more afterwards, makes more closely to combine between yarn and yarn, both ensure that the intensity of product, the outward appearance making again product is more good-looking.
More excellent, it is provided with in described cavity 3 and can place the platform 6 needing pressing gauze.Multilamellar gauze is placed on platform, is covered by film body the most again.
Additionally, also include the driving structure down pressed by upper die body 2.
It should be appreciated that for those of ordinary skills, can be improved according to the above description or be converted, and all these modifications and variations all should be belonged to the protection domain of this utility model claims.
