Description

Cooling device for molding stereoscopic glass continuous forming device

The invention is particularly directed to a new designer of a cooling device for a continuous atmosphere sintering forming device for molding a three-dimensional glass product, which has the simultaneous cooling of the upper and lower ends of the mold, so as to prevent the three-dimensional glass product in the mold from being damaged due to different cooling rates of the upper and lower ends. Missing.

According to the glass, because of its high light transmission characteristics, display devices (such as mobile phones, watches and other electronic products) are often selected as the outer casing of the window portion. It can be seen that the surface of the handheld electronic product is usually provided with a glass casing to protect the display module inside the product. At present, most of the glass casings are in the shape of a flat plate, so seams are formed on the upper surface of the electronic product. Furthermore, since the peripheral portion of the electronic product must retain a certain width of the mechanism portion for holding the flat glass, the top surface of the electronic product cannot be fully utilized. Therefore, three-dimensional or curved glass has gradually been applied to the glass casing of electronic products.

A flat glass housing is easier to manufacture, and a glass housing having a three-dimensional shape is relatively difficult to manufacture. At present, there are generally two methods for manufacturing a glass shell having a three-dimensional shape: the first one is to manufacture a plurality of flat glass units, and then form a glass shell having a three-dimensional shape by adhering the edges. The second type is: manufacturing a rectangular parallelepiped glass of a certain thickness, and then grinding it on the rectangular parallelepiped glass several times to form a three-dimensional shape having a plurality of sides. However, the above two methods are time consuming and labor intensive, and the production speed is very slow. In general, since the glass material is a flat plate, if a glass having a shape is to be produced, it is preferable to set the flat glass material to Between an upper module and a lower module, the upper mold, the lower mold, and the glass material are heated to soften the glass material. When the glass material is softened, the upper mold member and the lower mold member can be clamped, so that the upper mold member and the lower mold member together shape the shape of the glass material along a mold clamping direction, thereby producing a corresponding molded glass. . China Patent Publication No. M452174 "Molding Equipment for Molding Glass" (refer to the patent publication date of the announcement date of May 1, 2013), which comprises a female mold part, a first male mold part, and a second public A mold part, a support ram and a pressure bar. The first male mold member is disposed on the female mold member in an openable manner, and the second male mold member is disposed between the female mold member and the first male mold member. The support ejector is disposed on the female mold member, and the support ejector rod is used for pushing the second male mold member to support the second male mold member and the first male mold member A molded glass. The pressing rod is disposed on one side of the first male mold part, and the pressing rod is used for pressing down the first male mold part such that the first male mold part is opposite to the second male mold part The master mold member is moved to a clamping position to form the molded glass.
