Abstract
The utility model discloses a kind of O-shaped rubber seal injecting molding die of combined type, it is characterised in that has mold plate, lower die plate, punch-pin and cavity plate composition；Described the device punch-pin and lower die plate are interference fitted using axis hole, and cavity plate and mold plate are also interference fitted using axis hole.The punch-pin and cavity plate that the advantage is that the utility model can be replaced, and save manufacture die cost；Gathered around on punch-pin with multiple combinations model sealing ring；Using a multi-cavity mold, production efficiency is improved；And die joint improves the use of sealing ring not on working face.
Description
Technical field
The utility model belongs to processing of high molecular material forming field, and in particular to a kind of O-shaped rubber seal of combined type
Injecting molding die.
Background technology
In modern development in science and technology, with simple shape, good leakproofness obtains extensively should O-shaped rubber seal product
With.But during sealing ring is molding, there are many deficiencies, the die joint of mould is also the working face of sealing ring, influence
The use of sealing ring；And every kind of model sealing ring is required for one set of die, die cost is high, so that the price of sealing ring carries
It is high.To save sizing material, improve benefit, it is necessary to develop a kind of die device of the O-shaped rubber seal of combined type a multi-cavity mold.
The content of the invention
The purpose of this utility model is that in view of the deficiencies of the prior art, now provide a kind of combined type O-shaped rubber seal
Injecting molding die.For the mould in process of injection molding, once molding obtains substantial amounts of various types of sealing rings；Shaping
Mould only needs to change punch-pin and cavity plate, easy to use, reduces Mold Making cost；And working face improves not on die joint
The use of sealing ring；Using combined type a multi-cavity mold, production efficiency is improved, makes the quality uniformity of sealing ring more preferable.
To achieve the above object, the utility model uses following technical scheme：A kind of O-shaped rubber seal injection of combined type
Molding die, it is characterised in that be made of cope plate, lower template, multiple punch-pin and multiple cavity plates；The injecting molding die
Punch-pin and lower template, cavity plate and cope plate are using axis hole interference fit or thread connection；The punch-pin of the injecting molding die
There is its supporting cavity plate；The injecting molding die can once inject the product of multiple and different models；It is described to be injected into
It is convenient that type die punch and cavity plate are replaced.
Further, the upper heating plate with injector, lower heating plate are bolted respectively for the cope plate, lower template
Together, injector drives lower heating plate or upper heating plate to complete die sinking and mould assembling action using mode mechanically or hydraulically.
Further, the faying face of the punch-pin and cavity plate is pyramidal structure, and one or more is arranged not on the conical surface
With the O-ring seal groove of diameter, the groove of punch-pin and cavity plate forms multiple and different sizes and the O-ring seal of diameter during molding
Cavity, the die joint of these cavities is on the taper surface of punch-pin and cavity plate, without on its working face.
Further, there is a runner hole among each described cavity plate, which is a concave sphere, should
Concave sphere is in contact with the convex sphere of injector suspension nozzle；The cone-shaped top surface of each punch-pin has a U-type groove, cone
Two shallow rectangular recess are opened in shape side in a symmetrical manner, are communicated with one or more O-ring seal cavities, the two rectangles
Groove is communicated with the U-type groove of cone-shaped top surface respectively；The intermediate flow channel hole of each cavity plate is connected with the cone-shaped top surface U-type groove of punch-pin
It is logical.
The beneficial effects of the utility model are as follows：
(1) the utility model can produce different model sealing ring using the mould, save sizing material.
(2) mould is used, the die joint of sealing ring can be made not on working face.
(3) the utility model uses the mould, and more mold exchange is simple, saves die manufacturing cost.
(4) the utility model is the mould of a multi-cavity mold.

Fig. 3 is mold plate.
Fig. 4 is lower die plate.
Fig. 5 is mold closing mechanism.
Description of reference numerals：1- punch-pin；2- cavity plates；3- mold plates；4- lower die plates；Arrow flows into for sizing material in Fig. 5
Direction.
Embodiment
As shown in Fig. 1 to Fig. 5, a kind of O-shaped rubber seal injection mold lamps structure of combined type carries out labor.
In whole set of die, punch-pin 1 and lower die plate 4 are interference fitted using axis hole, and cavity plate 2 and mold plate 3 also use axis hole mistake
It is full of cooperation.Under the cooperation of existing injector and its auxiliary device, by hydraulic pressure or the lower heating plate of mechanical system driving or
The upper heating plate of person, realizes the process of die sinking and molding.
Floated nozzle in injector, through heating plate, is connected under the action of injection pressure with the spherical pore of cavity plate
Connect, sizing material is injected into cavity, under the action of heating plate, reach curing temperature.By adding under hydraulic pressure or mechanical system driving
When hot plate or upper heating plate realize die sinking action, suspension nozzle will be separated with cavity plate.
More than embodiment be intended merely to the utility model, and be not used as the restriction to the utility model, if
In the spirit of the utility model, the change to case study on implementation described above, modification will all fall special in the utility model
In the right of profit.
