By the present invention, can constitute different, nonplanar structure integratedly by this pressing mold corresponding structure in better simply mode.
It is known making glass ceramics member by mold pressing, for example at US-A-5, has described the small-sized plate-like piece that is used for electronic application in 588,979, has described the hollow body as pot in EP 0 736 497 A1.
The present invention be more particularly directed to produce the glass-ceramic kitchen range hole (kitchen range face) that is used for gas kitchen ranges, and relate to this kitchen range hole product in this production, that is to say, relate to king-sized planar spare, they have large size (typically, 60cm * 60cm); Have fully by the geometric modeling of claim, that is to say to have the hole that holds gas jet, have the special seamed edge design that is used for fixing the kitchen range face, and have other the structure that is different from this kitchen range facial plane.
The production of so-called " gas burner " (" Gas-Hob-Tops ") has obtained himself special technique Status of development, as beginning at this specification sheets as described in the place.
Glass-ceramic kitchen range this mold pressing, that be used for gas jet hole so can be designed according to first kind of design of the present invention like this, promptly in the kitchen range hole, design a hole that is used to hold an air fuel gas nozzle, the whole thickening of its seamed edge and the crimping that hoists.Can be more simply aspect the manufacturing technology it be being taken shape on this kitchen range hole integratedly as the seamed edge of increasing a seamed edge and a machinery thickening that the thing that prevents to boil overflows by this way.
According to two other alternative design of the present invention, the glass-ceramic kitchen range hole that is used for gas kitchen ranges can so be designed: the seamed edge in this kitchen range hole or the shape of thickening and being matched with a work wallboard integratedly; Perhaps frame-type ground 90 ° of crimpings downward or upward, wherein, the downward end face of the seamed edge of this frame shape forms the mounting face in this kitchen range hole on the work wallboard or on the cooking stove housing.
Cancellation is used to be connected to a work wallboard or is connected to the seamed edge processing cooking stove housing, in the past common by this way.What have very big advantage is, what an independent framework in this kitchen range hole neither be necessary.
