Opening is covered with the lateral surface of elastic rubber chest pad ontology, and volume shared by all through-holes is elastic rubber chest pad ontology total volume
40-80%.This chest pad can not only breathe freely under the premise of guaranteeing that elasticity, crushing resistance and moulding act on but also can effectively mitigate text
The weight of chest.
This brassiere with the chest pad is a kind of bra without steel rings, although bra without steel rings will not be to cream without steel ring
The raw compressing of house property, will not scratch human skin, but the bra without steel rings female user that needs chest full wear it is just good-looking,
Bra without steel rings can not be supported very well after the lesser female user wearing of chest, are caused breast without any support, are easily pulled down,
It is be easy to cause the mastoptosis of female user, adverse effect is caused to the health of female user.If will be toward thermoplastic elastomer material
Continue to be embedded in steel ring in brassiere made of expecting, that adds as steel ring with traditional foam-rubber cushion again, and steel ring oppresses breast, pierces through elasticity
Rubber chest pad, easy the problem of scratching skin, still have, in addition, steel ring is difficult to be placed in elastic rubber chest pad injection moulding process
In mold together with thermoplastic rubber material injection molding.
For this purpose, we have been devoted to the research and development of above-mentioned elastic rubber chest pad, do not have breast to solve elastic rubber chest pad
The problem of supporting role.

200 are completely encapsulated in elastic rubber chest pad extension；Then, it then is opened, switching position, molds again, so recycle.
Since plastics bow location structure 3024 including four thimbles 30241, ejector retainner plate 30242 and can drive each thimble
The 30241 thimble driving mechanisms 30243 stretched out or retracted, each location hole 30244 of the convex cup mould extension 3023 of the first rear mold 3
In be equipped with thimble 30241, the top of thimble 30241 is all exposed on the outer surface of convex cup mould extension 3023, moulds after injection molding
The medial surface of material bow 200 will form four Blind locating holes 2001, and when the first rear mold 302 is molded with mould 401 before chest pad, thimble
Driving mechanism 30243 drives each thimble 30241 to stretch out, and each thimble 30241 is still inserted in the Blind locating holes 2001 of plastics bow 200
And drive plastics bend 200 surfaces far from convex cup mould extension 3023, make plastics bow 200 in cup die cavity extension 4012 with it is convex
In the space that cup mould extension 3023 is constituted.
In addition, each shank 3025 is in the space that second glass of die cavity 4011 and convex cup mould 3022 are constituted after molding
In and the movable end of shank 3025 and the cambered surface of second glass of die cavity 4011 be engaged, the elastic rubber chest pad after injection molding is same
With multiple through-holes, under the premise of guaranteeing that elastic rubber chest pad elasticity, crushing resistance and moulding act on, so that elastic rubber chest pad
It is lighter, and there is good gas permeability；When die sinking, thimble driving mechanism 30243 further drives thimble 30241, rear pattern plate
3021, molded elastic rubber chest pad, which synchronizes, moves out, and each shank 3025 is motionless in rear die station 2 due to being fixed on, respectively
Shank 3025 retracts backward relative to molded elastic rubber chest pad, to realize demoulding.Above-mentioned rear pattern plate 3021 and top
The power output end connection of needle drive mechanism 30243 is a kind of optimal scheme, is driving and the thimble of rear pattern plate 3021
Driving uses same thimble driving mechanism 30243, this spline structure is simpler, certainly, after those skilled in the art can be set
The independent driving mechanism of template belongs to the direct replacement of the prior art.
In addition, the bottom surface due to arch vallecular cavity 3012 is equipped with multiple pillars 3017, and in injection-moulded plastic bow 200, plastics bow
Multiple limit holes 2002 corresponding with pillar 3017 are generated on 200, when carrying out the injection molding of elastic rubber chest pad, in limit hole 2002
Thermoplastic rubber material form thermoplastic elastomer item, thermoplastic elastomer item plays the role of similar rivet and draws plastics bow 200
Tightly, it positions, and wrapped to 200 progress of entire plastics bow, sufficiently enwinds plastics bow 200, so that plastics bow 200 and elastic rubber
Chest pad one integrated mass.
In addition, it should be noted that, the specific embodiments described in this specification, each section title etc. can not
Together, all equivalent or simple changes done according to structure, feature and principle described in the concept of the patent of the utility model are included in this
In the protection scope of utility model patent.Those skilled in the art of the present invention can be to described specific reality
Example is applied to do various modifications or additions or be substituted in a similar manner, structure without departing from the utility model or
Beyond the scope defined by this claim, it all should belong to the protection range of the utility model.
