Description
Technical field
The utility model relates to a kind of stripper apparatus, especially relates to a kind of device that is used for the bellows of injection mo(u)lding is carried out Pneumatic demould.
Background technology
At industrial circle, bellows has widely to be used, and often needs to use bellows as the hermetically sealed case of rich property shaft coupling, rich property shaft coupling itself and collapsible container etc.Blowing or injection moulding process are adopted in the manufacturing of bellows usually, the bellows that the blow moulding manufacturing forms, and its cost density is poor, easily because of wearing and tearing damage, has influenced its service life in use greatly.The bellows that the injection moulding manufacturing forms is because of its product density height, have higher service life and obtain user's extensive approval, but injection moulding is made the problem that there is demoulding difficulty in the bellows of moulding, the general employing of the conventional injection moulding demoulding is manual or utilize the mould core bar that bellows is released, in knockout course, all cause bellows and mould damage because of friction easily, not only influence the quality of product, and aggravated the wearing and tearing of mould, influenced the service life of mould.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of bellows Pneumatic demould device that can carry out safe and reliable Pneumatic demould to the bellows of injection mo(u)lding is provided.
The purpose of this utility model is achieved in that a kind of bellows Pneumatic demould device, described stripper apparatus includes cover half and the core bar that is embedded in the cover half, described cover half top offers a counterbore, the bottom is provided with an air cavity, the centre is provided with an air flue counterbore is connected with air cavity, described air cavity bottom is provided with an air admission hole, described core bar includes the connecting rod that is inserted in air flue, described connecting rod top is with a plug, the bottom is connected with a stop bit spare, described plug and stop bit spare place respectively in counterbore and the air cavity, have the bellows after the injection mo(u)lding to be coated on the dynamic model, and described bellows are the barrel-like structure of a top closure.
A kind of bellows Pneumatic demould of the utility model device, described plug and counterbore size are complementary, and are provided with one between described plug and the connecting rod and regulate pin.
A kind of bellows Pneumatic demould of the utility model device, described stop bit spare is strip or disk-like structure, and when stop bit spare was list structure, the diameter of described stop bit spare was less than the diameter of air flue, when stop bit spare was disk-like structure, described air cavity top radially had some grooves.
Compared with prior art, the beneficial effects of the utility model are:
The utility model Pneumatic demould device is owing to charged into gases at high pressure between mould and bellows, thereby mould can directly not contact with bellows, avoided damage between the two, not only improved the quality of product, and the wearing and tearing of mould, the service life of the mould of prolongation have been reduced.

The specific embodiment
Referring to Fig. 1 ~ 9, a kind of bellows Pneumatic demould device that the utility model relates to, described stripper apparatus includes cover half 1 and the core bar 3 that is embedded in the cover half 1, described cover half 1 top offers a counterbore 1.1, the bottom is provided with an air cavity 1.2, the centre is provided with an air flue 1.3 counterbore 1.1 is connected with air cavity 1.2, described air cavity 1.2 bottoms are provided with an air admission hole 1.4(as shown in Figure 5), described core bar 3 includes the connecting rod 3.1 that is inserted in air flue 1.3, and the diameter of described connecting rod 3.1 is less than the diameter of air flue 1.3, described connecting rod 3.1 tops are with a plug 3.2, the bottom is connected with a stop bit spare 3.3, form the structural member (as shown in Figure 6) of a cross section for " worker " font, described plug 3.2 and stop bit spare 3.3 place respectively in counterbore 1.1 and the air cavity 1.2 (as shown in Figure 4), and described plug 3.2 is complementary with counterbore 1.1 sizes, be provided with one between described plug 3.2 and the connecting rod 3.1 and regulate pin 3.4, be used to regulate the height of plug 3.2, described stop bit spare 3.3 can be strip or disk-like structure, when stop bit spare 3.3 is list structure, the diameter of described stop bit spare 3.3 is less than the diameter of air flue 1.3, when stop bit spare 3.3 is disk-like structure, described air cavity 1.2 tops radially have some grooves, making that gas still can arrive conducting when stop bit spare 3.3 contacts with air cavity 1.2 enters in the air flue 1.3
Have the bellows 5 after the injection mo(u)lding to be coated on the dynamic model 2, and described bellows 5 is the barrel-like structure (as shown in Figure 3) of a top closure.
Operation principle of the present utility model is:
One, injection mo(u)lding: constitute mould by cover half 1 and the dynamic model 2 that is Harvard's formula syndeton, dynamic model 2 closed backs constitute one with cover half 1 and are used for the die cavity 4 of injection moulding, thereby inject raw material, make bellows 5; Those skilled in the art also can select for use dynamic model 2 structures of other Rational structure to carry out injection operation according to cover half 1.
Two, the demoulding: after bellows 5 injection mo(u)ldings, air inlet pipe 6 is linked to each other with air admission hole 1.4, subsequently, feed gases at high pressure, with core bar 3 jack-up (as shown in Figure 8) upwards by air inlet pipe 6, make gas enter between bellows 5 and the cover half 1 through air flue 1.3, the gases at high pressure that continue to feed are peeled off the outer surface (as shown in Figure 9) of cover half 1 with the inner surface of bellows 5, thereby have realized stripping operation, at this moment, close gases at high pressure, can easily bellows 5 be taken off from cover half 1.
Three, following process: bellows 5 top seal end-grain cutting are sliced off the finished product bellows that can obtain required both ends open.
