It is a kind of in mould of inner sponge cores punching press threaded hole and production and preparation method thereof
Technical field
The invention belongs to a kind of utensil of the setting threaded hole on flexible products, more particularly to one kind is in inner sponge cores punching press
Mould of threaded hole and production and preparation method thereof.
Background technology
It is dry in northern China, a large amount of suspended particulate substances and dust are contained in air, even produces and raises during strong wind
Dirt.Some allergic constitutions person triggers the diseases such as cough, asthma due to suction pollen, dust mite etc..Meanwhile, being air-dried easily makes one
Mood is irritated, and dizzy uncomfortable in chest, larynx nose is uncomfortable.Generally, for blocks dust, people can go on a journey with mouth mask, still, and mouth mask is still
There is the inconvenience of many, the occupation that such as traffic police has it further provides that can not be with mouth mask.Now, also there is a kind of asal filter, can mistake
Some viruses and fine particle (including PM2.5, PM10 etc.) are filtered, this filtration relies primarily on minimum aperture, but minimum
Aperture while filtration fraction fine particle, also can also cause human body uncomfortable, this resistance human body respiration formation resistance
Power can cause human body itself gas flow not enough, and gas flow deficiency easily causes internal anoxic, can so cause note for a long time
Recall power decline, blood pressure rise etc., especially for for inherently having a crowd of respiratory disease, more uncomfortable, influence is strong
Health.
It is necessary to obtain a kind of dedusting humidification utensil for not covering face, and the dedusting humidifier inner core in nasal cavity is soft
Matter sponge material, by inner core spiral pipeline dedusting, by the scheme for the increase suction humidity that added water in inner core, works well, solves
Determine the shortcoming that existing mouth mask and asal filter be present, however, because sponge is soft material, it is difficult to make through hole, especially
It is spiral through hole.
The content of the invention
In order to solve the above problems, the present invention, which is provided, a kind of in the mould of inner sponge cores punching press threaded hole and its manufacture and to be made
With method, threaded hole can be obtained on soft material using this mould and method.
The technical solution adopted by the present invention is as follows:

Hole is installed by punching pin.
(2) gear of lower mould die shank is connected into actuating unit, actuating unit band moving gear rotates predetermined angular, and lower mould is followed
Rotation.
(3) inner sponge cores are arranged between upper and lower die face, inner sponge cores two ends are fixed by the fixed pin of upper and lower die face,
Lower mould actuating unit drive under rotate predetermined angular, can set be rotated by 90 °, 180 °, 270 ° or 360 °, punching pin pair after rotation
The lower any nib of mould of standard, the downward punching press of punching pin, inner sponge cores obtain through hole.
(4) upper and lower mould return, takes out inner sponge cores, the through hole of inner sponge cores is because inner core rotates return and obtains one
Threaded hole or helical pipe.
The beneficial effects of the present invention are:Interlinked mechanism is set in lower mould, a variety of helical angles can be set in inner sponge cores
The pipeline of degree, and it is readily obtained the cheap inner core of batch;And the nasal cavity dedusting humidifier of this helical pipe is provided with inner core,
During air-breathing, air is rotated by helix tube, and the dust in air is sticked on duct wall under the influence of centrifugal force, and air
The pipeline turnover that conrotatory turns, air-flow flux is big, and without resistance, the breathing of people is not influenceed;Due to adding clear water, Ke Yi in inner core
By moisture evaporation during breathing, increase the air humidity of suction, can avoid due to being air-dried the uncomfortable influence brought.
