Description

Three-dimensional molding glass continuous molding device

technical field

The utility model belongs to the technical field of continuous atmosphere sintering, in particular to a new design of a continuous atmosphere sintering device for three-dimensional glass molding, which has the effect of continuous, high-efficiency and high-quality molding three-dimensional 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 "Forming 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. However, it is still unable to meet the needs of the industry for continuous and rapid production of high-quality molded three-dimensional glass, which 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.

The applicant previously filed a patent application for "Molding Three-dimensional Glass Continuous Forming Device", which is mainly composed of a furnace body, an inner conveying channel, an outer conveying channel, an exchange system and a pressurizing system. The inner conveying channel is set inside the furnace body, and Connect the exchange system on both sides of the furnace body, the outer conveyor is set outside the furnace body, and connect the exchange system on both sides of the furnace body, the aforementioned inner conveyor is provided with slide rails, as a track for the carrier plate to move, the furnace body It is a closed type, and the protective gas is introduced.
