Abstract

The utility model relates to a double side wing forming mold, which comprises a base and a forming ring, wherein a fixing forming ring is fixed on the base; a movable forming ring is formed on an inner wing with a weight dropper; the fixing and the movable forming rings are hinged together. The utility model is characterized in that an outer forming ring is arranged outside the movable forming ring; outer wings with weight droppers can be positioned on the inner wing through a longitudinal shaft; the end part of each outer wing is provided with a support; a supporting foot of the outer forming ring falls on the support for positioning; the outer wings of both sides can be coupled together through a connecting rod. A baking bend is made by twice forming of the outer forming ring and the moveable forming ring; the utility model can prevent the unfavorable phenomenon of mold trace, or scalloping or sagging, etc. of glass.

Description

Dual flank forming mould

The utility model belongs to the sheet glass manufacture field, particularly a kind of dual flank forming mould.The existing mould that is used for the laminated glass brake forming has only a flank mostly, its structure includes base and moulding ring, the moulding ring is divided into decides moulding ring and moving moulding ring, deciding the moulding ring is fixed on the base, moving moulding ring is fixed on the flank that has weight, moves the moulding ring and decide the moulding ring hinged by hinge.The glass of moulding generally becomes class rectangular-shaped, the middle part, long limit of class rectangular mould is for deciding the moulding ring, and two ends are moving moulding ring, big glass when baking curves type the middle part by deciding the moulding ring forming, and two ends glass is after baking is soft, under the cooperation of weight gravity, flank drives moving moulding and makes progress the continuous brake forming of glass gradually around pin joint.The mould of this structure can cause following problem in producing big radian, the curved glass process of big sphere baking: 1, mold-mart is obvious: for the bigger glass of sinuousness, the size of its development size after than bending is much bigger, therefore in the time of on glass, just very wide with the mould contact position from the glass edge edge, like this when glass softens moulding, glass is just very long by the distance that the contact position slides into the edge, thereby causes the large-area slip vestige of glass, influences the visual appearance of glass; 2, the goodness of fit is uncontrollable: (arc is deeply greater than 25～1000mm), and the length direction sagitta is greater than the glass of 100～1000mm, easily produces flounce at the side of glass, and this has influenced glass entrucking performance for the glass side camber; 3, the glass that the side sphere is big can't moulding: when glass side sphere is very big, usually sphere is greater than 80mm, in pre-treatment blanking place, this part need be protruded a very big part, and about 30mm～400mm is when glass is placed on the mould, convex part glass does not support because of having, glass is softening when baking is curved, and is under the action of gravity of self, sagging to the opposite direction of normal curvature direction.

The purpose of this utility model is in order to solve existing mold in the deficiency that the curved large glass process of baking exists, to design a kind of dual flank forming mould with inside and outside two moving moulding rings.

Task of the present utility model is achieved in that a kind of dual flank forming mould, comprise base and moulding ring, deciding the moulding ring is fixed on the base, moving moulding ring is fixed on the inner wing that has weight, move the moulding ring and decide the moulding ring hinged by hinge, it is characterized in that being provided with moulding ring outside in the outside of moving moulding ring, the outer wing of band weight is positioned on the inner wing by the longitudinal axis, the end of outer wing is provided with a support, the feet of outer moulding ring drops on the support and locatees, and the outer wing of both sides links together by connecting rod.When load is bent in baking, the sheet glass of big expanded area is supported by outer moulding ring, when preliminary drying is bent extremely necessarily, push away or draw outer wing to make it rotate a Small angle around the longitudinal axis, propping up the corresponding displacement of support makes the feet of outer moulding ring lose supporting, outer moulding ring comes off, and glass is replaced by moving moulding ring and supported, and continues moulding.

The utility model compared with prior art only increases outer moulding ring, reasonable in design, and baking is curved simple to operate.It has following advantage: when load preheating and preliminary drying are bent beginning, glass and outer moulding loop contacts, be molded into an about half when baking is curved, push outer moulding ring open, glass and outer moulding ring are broken away from, continue moulding with moving moulding loop contacts at once, leave mold-mart with regard to reducing because of slip causes glass surface like this; (arc is deeply greater than 25～1000mm) for the glass side camber, the length direction sagitta is greater than the glass of 100～1000mm, the moving moulding ring radian of outer moulding ring camber ratio is slightly flat, when glass ware forming, earlier by the moulding of outer moulding ring radian, after outer moulding ring breaks away from, with moving moulding loop contacts, the radian moulding of pressing the moulding ring again, glass forms twice moulding like this, prevent that modification makes the glass deformation amount cause flounce too greatly because of one time, has influenced the glass radian; When glass side sphere was very big, sphere was greater than 80mm usually, and when the pre-treatment blanking, convex part is long to be supported by outer moulding ring, prevents that the softening back of glass is sagging.

Below in conjunction with concrete legend the utility model is described further:

The dual flank forming mould of Fig. 1 partial schematic diagram

Fig. 2 is Figure 1A-A direction view

With reference to Fig. 1 and Fig. 2, a kind of dual flank forming mould, comprise base 1 and moulding ring, the moulding ring is divided into decides moulding ring 2 and moving moulding ring 3, deciding moulding ring 2 is fixed on the base 1, moving moulding ring 3 is fixed on the inner wing 4 that has weight 41, move moulding ring 3 and decide moulding ring 2 hinged by hinge 5, wherein be provided with moulding ring 6 outside in the outside of moving moulding ring 3, the outer wing 7 of band weight 41 is positioned on the inner wing 4 by the longitudinal axis 8, makes outer wing 7 do the horizontal direction swing around axle, the end of outer wing 7 is provided with a support 71, the feet 61 of outer moulding ring 6 drops on location on the support 71, and feet 61 loses the support of a support 71, and outer moulding ring 6 promptly can drop.The outer wing 7 of both sides links together by connecting rod 72, makes it produce synchronization action.Base 1 is provided with a banking stop 9 below inner wing 4 weights 41 strokes, guarantee that moulding is accurate.

Above-described hinge 5 also can be substituted by rivet, also promptly decides moulding ring 2 and moving moulding ring 3 and is in the same place by rivet, and moving moulding ring 3 can be flexible around the rivet rotation.Only draw half of mould among this figure.

Claims

1, a kind of dual flank forming mould, comprise base and moulding ring, deciding the moulding ring is fixed on the base, moving moulding ring is fixed on the inner wing that has weight, and moving moulding ring is characterized in that being provided with moulding ring outside in the outside of moving the moulding ring with decide the moulding ring hinged by hinge, the outer wing of band weight is positioned on the inner wing by the longitudinal axis, the end of outer wing is provided with a support, and the feet of outer moulding ring drops on the support and locatees, and the outer wing of both sides links together by connecting rod.
