Description

Heating device for three-dimensional glass continuous molding equipment

technical field

The utility model belongs to the technical field of heating devices, in particular to a new structure design of a heating device for a three-dimensional molded glass continuous molding device, which has the advantages of less heat loss and good conduction, and is suitable for continuous molding of relatively high-temperature three-dimensional molded glass.

Background technique

Press, because glass has high light transmission characteristics, so display devices (such as mobile phones, watches and other electronic products) often choose it as the shell of the window part. You can see that the surface of handheld electronic products 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 a seam will be formed on the upper surface of the electronic product. Furthermore, since a certain width of the mechanism must be reserved around the electronic product to hold the flat glass, the top surface of the electronic product cannot be fully utilized. Therefore, three-dimensional or curved glass has been gradually applied to glass casings of electronic products.

The flat glass case is relatively easy to manufacture, but the glass case with a three-dimensional shape is relatively difficult to manufacture. At present, there are generally two methods for manufacturing a three-dimensional glass case: the first method is: manufacturing a plurality of flat glass units, and then forming a three-dimensional glass case by pasting the edges. The second method is to manufacture a rectangular parallelepiped glass with a certain thickness, and then grind the rectangular parallelepiped glass multiple times to form a three-dimensional shape with multiple sides. However, the above two methods are time-consuming and labor-intensive, and the production speed is very slow. Generally speaking, since the glass material is a flat plate, if a glass with a shape is to be produced, it is better to arrange the flat glass material between an upper mold and a lower mold, and then heat the upper mold , the lower module and the glass material to soften the glass material. When the above-mentioned glass material is softened, the upper mold and the lower mold can perform a mold closing action, so that the upper mold and the lower mold can jointly shape the shape of the glass material along a mold-closing direction, so as to produce the corresponding molded glass . China Taiwan Patent Announcement No. M452174 "Molding Equipment for Manufacturing Molded Glass" (announcement date May 01, 2013 patent announcement data reference), which includes a female mold part, a first male mold part, a second A male mold part, a supporting ejector rod and a pressing rod. The first male mold part is arranged on the female mold part in an openable and closable manner, and the second male mold part is arranged between the female mold part and the first male mold part. The supporting ejector rod is passed through the female mold part, and the supporting ejector rod is used to push against the second male mold part, so as to support the second male mold part and the first male mold part to be clamped together A molded glass. The pressing rod is arranged on one side of the first male mold part, and the pressing rod is used to press down on the first male mold part so that the first male mold part is opposite to the second male mold part The mother mold part is moved to a clamping position for molding the molded glass.

A molding machine for making 3D three-dimensional molded glass using hot press molding technology may use a heating device to directly heat the mold, which includes an upper heating device installed at the lower end of the pressing device and a lower heating device located below. The existing Please refer to Fig. 1A ~ Fig. 1C for the heating device, which is mainly composed of a support base A, a heating block B and a heating plate C fixed together with screws, wherein the heating block B is provided with an appropriate number of perforations D to set The rod-shaped heating tube E is inside to heat the heating block B, and conduct the heat to the heating plate C, and then use the heating plate C to heat the mold, and then heat and soften the flat glass to be formed on the molding surface of the mold and place it in the mold forming. However, this existing heating device has a lack of heat conduction loss due to the combined structure of the heating block B and the heating plate C, and the rod-shaped heating tube E cannot provide sufficient heating temperature to the mold. Higher and higher (especially the high softening temperature of aluminum-containing glass), it can no longer meet the needs of the industry, and it is missing. This is the biggest deficiency in the current prior art, and this deficiency is a difficult problem to be overcome urgently in the industry.
