Abstract
The utility model discloses a forming device for thermal expansion auxiliary prepregs of silicon sheets. The device comprises an upper mould, a lower mould and the silicon sheets. The silicon sheets are attached into mould cavities of the upper mould and/or the lower mould. Preferably, mould release agent layers are coated in the mould cavities of the upper mould and the lower mould, and the silicon sheets are attached onto the mould release agent layers in the mould cavities of the upper mould and/or the lower mould. Compared with the prior art, the forming device has the advantages that by the aid of thermal expansion of silicon, the silicon sheets uniformly expand and generate internal pressure in a heating-forming process, prepreg sheets uniformly pressed in all directions, accordingly, the lateral face of a product is also sufficiently and uniformly pressed, and high layer-to-layer bonding strength is obtained.
Description
Technical field
The utility model relates to a kind of composite material forming device, relates in particular to the auxiliary prepreg shaped device of a kind of silica gel sheet thermal expansion.
Background technology
For prepreg mold pressing thermoforming; When goods contained complex-curved structure, there was angle even vertical its side with moulding press pallet plane, the moulding press pressurization; The power that the side receives is decomposed into the normal pressure of the normal direction along the side and the interior pulling force of tangential; Because the moulding press applied pressure is broken down into the power of both direction, cause the suffered normal pressure in side not enough, its interfacial bonding strength is descended.Again because the influence of interior pulling force, and produce internal stress, cause the product distortion.
The utility model content
The purpose of the utility model is that the above-mentioned deficiency that overcomes the prior art existence provides the thermal expansion of a kind of silica gel sheet to assist the prepreg shaped device.This device utilizes the thermal expansion of silica gel sheet to assist the prepreg moulding, makes that the interlayer adhesion of prepreg moulded products side is strong, product is not yielding.
The purpose of the utility model realizes through following technical scheme:
The prepreg shaped device is assisted in a kind of silica gel sheet thermal expansion that the utility model relates to, and comprises mold, bed die and silica gel sheet, and said silica gel sheet pastes in the die cavity of said mold and/or bed die.
Preferably, be coated with releasing agent layer in the die cavity of said mold and bed die, said silica gel sheet is on the releasing agent layer that pastes in the die cavity of said mold and/or bed die.
Preferably, the shape of said silica gel sheet is that shape needs according to the prepreg moulded products cut.
Preferably, the shape of said silica gel sheet cuts with cutting die and forms.
Preferably, the thickness of said silica gel sheet is 0.8～2mm.
Preferably, said device can be placed on pressurization on the moulding press, heating.
Preferably, said mold, bed die are stainless steel mould.
Compared with prior art; The beneficial effect that the utlity model has is: the device of the utility model utilizes silica gel sheet hot expansibility; In hot briquetting; Press in silica gel sheet expanded by heating produces, make the prepreg tablet on all directions, obtain uniform pressure, thus make prepreg moulded products side the interlayer adhesion by force, product is not yielding.
