Description
Technical field
The present invention relates to the technical field of hollow blow molding equipment, refer more particularly to a kind of mould that is used to make breathing mask.
Background technology
Breathing mask cooperates equipment uses such as oxygen when being the help patient respiration; Raw material is special PVC (polyvinyl chloride) material in medical; The PVC material is a kind of amorphism material, has low flammability, high strength property, weather variability and good geometrical stability.This product top and bottom thickness is different, is used for and contact patients face thickness 0.05～0.08mm only, thus pleasant when making patient worn; Thick 0.3～the 0.4mm of another side, thus can weld better with the fixed cover of oxygen pipeline; Be full of air in the middle of the product, under the 3MPa pressure test, can not there be breakage at its thin place.
The present mould that is used to make breathing mask; Its structure comprise two can involutory each other mould, be respectively arranged with die cavity in the involutory surface of two moulds, the degree of depth of two die cavities is identical; Two moulds can be combined to form gas hole; One end of gas hole is connected with die cavity, and the other end of gas hole is connected with the outside of mould.During production, two disposable involutory putting in place of mould obtain finished product just from gas hole to die cavity inside air blowing cooling forming then, and then the burr of first finished product are cut to remove obtain finished product.
The above-mentioned shortcoming that is used to make the mould of breathing mask is:
1, because the degree of depth of two die cavities is identical; So the bad mold joint of the finished product that obtains is in the centre position; After with thick of the finished product fixed cover welding with oxygen pipeline, the fixed cover of oxygen pipeline occupies the area of half breathing mask, thus the comfort level when influencing patient worn.
2, since two moulds to fashionable, the air between finished product outer surface and the mold cavity wall has little time to discharge, thereby causes the finished product outer surface to have many nickings, pit etc. to influence the finished product outward appearance.
3, two moulds are to fashionable, and unnecessary material forms burr, and the burr of first finished product are divided into two parts; A part of burr that are positioned at the finished product middle part for the heart type, another part are to be positioned at the outside burr of finished product, and burr are structure as a whole with first finished product; Need artificial cutting to remove, operating efficiency is low, and in cutting removal process, easily finished product is caused breakage; Burr place after artificial in addition cutting is removed is rough, the comfort level in the time of can influencing patient worn.
Summary of the invention
Technical problem to be solved by this invention is: a kind of mould that is used to make breathing mask is provided, the bad mold joint of prepared finished product not in the centre position, the finished product smooth outer surface, and need not again to remove burr through artificial cutting.
For addressing the above problem; The technical scheme that the present invention adopts is: the mould that is used to make breathing mask; Comprise can be involutory each other left shaping mould and right shaping mould, be respectively arranged with levorotation chamber and right die cavity in the involutory surface of left shaping mould and right shaping mould, left shaping mould and right shaping mould can be combined to form gas hole; One end of gas hole is connected with levorotation chamber and right die cavity; The other end of gas hole is connected with the outside of left shaping mould and right shaping mould, and the degree of depth of described levorotation chamber and right die cavity is different, and being respectively arranged with in levorotation chamber and the right die cavity can involutory each other inserting; The peripheral edge place of levorotation chamber and right die cavity is provided with respectively can involutory each other fringing; Be respectively arranged with discharge duct in left side shaping mould and the right shaping mould, the two ends that are arranged in the discharge duct of left shaping mould are connected with the outside of levorotation chamber and left shaping mould respectively, and the two ends that are arranged in the discharge duct of right shaping mould are connected with the outside of right die cavity and right shaping mould respectively; The left side of left side shaping mould is disposed with left stock mould and left deflash mould; Left side deflash mould is connected through inserting in left side axle and the levorotation chamber, and the right side of right shaping mould is disposed with right stock mould and right deflash mould, right deflash mould through right with right die cavity in insert and be connected.
Be respectively arranged with cooling pipe in described left shaping mould and the right shaping mould, cooling pipe is netted and gathers in left shaping mould and right shaping mould inside, and the end of cooling pipe is connected with the outside of left shaping mould and right shaping mould.
Be provided with left back-moving spring between described left shaping mould and the left stock mould; Be provided with right back-moving spring between described right shaping mould and the right stock mould.
The left side of described left shaping mould is provided with left guide pillar, and left stock mould and left deflash mould penetrate and be arranged on the left guide pillar; The right side of described right shaping mould is provided with right guide pillar, and right stock mould and right deflash mould penetrate and be arranged on the right guide pillar.
Described left side axle is provided with the left side back-moving spring of inserting; Described right axle is provided with the right side back-moving spring of inserting.
The invention has the beneficial effects as follows: the above-mentioned advantage that is used to make the mould of breathing mask is: 1, because the degree of depth of two die cavities is different; So the bad mold joint of the finished product that obtains is not or not the centre position; And sake is greater than thick; After with thick of the finished product fixed cover welding with oxygen pipeline, the fixed cover of oxygen pipeline occupies the area of less breathing mask, thereby the comfort level when making patient worn is improved.
2, in two shaping moulds, be provided with vacuum device, the air between finished product outer surface and the shaping mould die cavity wall in time discharged, thereby make the finished product smooth outer surface, finished product is attractive in appearance.
3, be provided with at the middle part of die cavity and insert, the peripheral edge place of die cavity is provided with fringing, involutory with fringing inserted; Can the burr of first finished product be removed; Thereby need not to remove burr through artificial cutting again, improved operating efficiency, also improved yield rate; The burr place smooth surface of finished product, thus the comfort level when making patient worn is improved.
