Title
(EN) Curved graphite mould structure of 3D curved surface glass apron heat
(ZH) 一种3D曲面玻璃盖板热弯石墨模具结构
Abstract
(EN)
The utility model relates to a glass mold technical field especially relates to a curved graphite mould structure of 3D curved surface glass apron heat, including terrace die, die, be provided with the location boss in the middle of the both sides of terrace die, it has clip -shaped slot to open on the terrace die, clip -shaped slot's centre is provided with the core, be provided with the arc angle around the core, the corner sets of core has the arc chord angle, the middle pressing platform no. 1 that is provided with all around of core, pressing platform's no. 1 corner sets has the arc wall, be provided with positioning groove in the middle of the both sides of die, be provided with square boss on the die, it has the die cavity to open in the middle of the square boss, the bottom of die cavity is provided with the arc wall all around, the corner sets of die cavity has the arc groove, the middle pressing platform no. 2 that is provided with all around of die cavity, pressing platform's no. 2 corner sets forces the sky arc groove, adopts the setting of forcing the sky arc groove, and when four curved angles of glass heat, produced internal stress can not make four angles of glass produce the folding mark mark, warp the scheduling problem through forcing the release of sky arc groove.
