the technical scheme that the utility model solves the problems of the technologies described above is:
the Integral molding device for insoles of silica gel and steel disc in a kind of panel computer seal washer, comprise the patrix of combining successively, middle mould and counterdie, between this patrix, middle mould and counterdie, be formed with the material space of rectangle, in one of them limit in the material space of this rectangle, be provided with steel disc, wherein, steel disc is positioned at below, and silica gel is positioned at top; In the material space of steel disc is set, described middle mould has along outwards stretch into the extension of counterdie perpendicular to die sinking direction, and the bottom surface of described steel disc is fitted in the upper surface of this extension; In described counterdie, be provided with the locating dowel of upwards passing through this extension and steel disc with described extension corresponding position.
a preferred version of the present utility model, wherein, described counterdie is connected on solid plate, and this solid plate is provided with auxiliary mould-opening device, and this auxiliary mould-opening device comprises thimble and spring, and described thimble passes through counterdie and extend in middle mould.By this auxiliary mould-opening device, can, after patrix is opened, middle mould be ejected.
a preferred version of the present utility model, wherein, in the material space of steel disc is set, the side of steel disc and middle mould fit.After middle mould die sinking, the side of steel disc is left counterdie and is revealed like this, is convenient to be taken off.
a preferred version of the present utility model, in the material space of steel disc is set, is provided with two bossings that make progress in the part that silica gel is set.After silica gel moulding, can between described two projections at top, form a groove like this, for location.
a preferred version of the present utility model, in the unclassified stores space outside steel disc is set, its cross section is " C " type.After silica gel moulding, can form seal groove at sidewall like this, can wrap up the screen board of panel computer.
the utility model compared with prior art has following beneficial effect:
in the utility model, due in the material space of steel disc is set, described middle mould has along outwards stretch into the extension of counterdie perpendicular to die sinking direction, and the bottom surface of described steel disc is fitted in the upper surface of this extension; In described counterdie, be provided with the locating dowel of upwards passing through this extension and steel disc with described extension corresponding position; Therefore when middle mould die sinking, described extension can promote the steel disc demoulding together, make steel disc leave smoothly counterdie and locating dowel, between steel disc and silica gel, can not produce the power of tearing, in final therefrom mould, taking off Liancheng rail together hands over and steel disc, guarantee the effect that is tightly connected between silica gel and steel disc, improved the quality of panel computer.
