Description

Cooling device for continuous three-dimensional glass molding device

The present invention is particularly directed to a new designer of a cooling device for a continuous atmosphere sintering molding device for molded three-dimensional glass products. Is missing.

Press, because glass has high light transmission characteristics, so display devices (such as mobile phones, watches and other electronic products) choose it as the shell of the window part. The surface of handheld electronic products is usually provided with a glass shell to protect the display module inside the product. At present, most of the glass shells have the shape of a flat plate, so a seam is 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 the glass shell of electronic products.

The flat glass case is easier to manufacture, and the three-dimensional glass case is more difficult to manufacture. At present, there are generally two methods for manufacturing a glass case with a three-dimensional shape. The first method is to manufacture a plurality of flat glass units, and then form a glass case with a three-dimensional shape by sticking edges. The second method is: manufacturing a rectangular parallelepiped glass with a certain thickness, and then grinding the rectangular parallelepiped glass several 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 set the flat glass material to Between an upper module and a lower module, the upper module, the lower module, and the glass material are then heated to soften the glass material. When the above-mentioned glass material is softened, the upper mold and the lower mold can perform a clamping action, so that the upper mold and the lower mold jointly shape the shape of the glass material in a clamping direction, thereby producing corresponding molded glass. . China Patent Bulletin No. M452174 "Molding Equipment for Manufacturing Molded Glass" (refer to the patent publication information on May 01, 2013), which contains a female mold part, a first male mold part, and a second male mold part. Mold parts, a support rod and a pressure rod. The first male mold part is disposed on the female mold part in an openable and closable manner, and the second male mold part is disposed between the female mold part and the first male mold part. The support ejector is penetrated through the female mold part, and the support ejector is used to push against the second male mold part, thereby supporting the second male mold part and the first male mold part to be clamped together. A moulded glass. The pressing rod is arranged on one side of the first male mold part, and the pressing rod is used to press down 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 mold clamping position, thereby molding the molded glass.

The applicant previously proposed the approved M512584 "Continuous Molding Device for Molded Three-Dimensional Glass", which is a new design for the continuous molding device designed for molded three-dimensional glass products. It is mainly composed of the furnace body, the inner conveyor, the outer conveyor, the exchange system and Composed of a pressurized system, the inner conveyor is located inside the furnace body and is connected to the exchange system on the two sides of the furnace body. The outer conveyor is located outside the furnace body and is connected to the two sides of the furnace body. The track is equipped with slide rails as the track for the carrier board to move. The furnace body is closed and introduced with protective gas. According to the process, it is divided into heating zone, high-temperature molding zone, slow-down zone and cooling zone, heating zone, high-temperature molding. Zones and slow-down zones are equipped with heat-resistant materials and heating elements depending on the temperature required by the process. The cooling zone has cooling devices. The pressurization system is located in the high-temperature forming zone. The flat glass to be formed is placed in the mold forming surface, and the mold is placed in Carrier board, The furnace body is preheated in the heating zone, the glass in the high temperature forming zone is softened and pressurized by the pressure system, and then sent out of the furnace body after the temperature in the slow-down zone and the cooling in the cooling zone, and then demoulded. It can indeed achieve the effect of continuous, high efficiency and high quality molding and molding of three-dimensional glass.

However, the cooling device of the conventional three-dimensional glass continuous molding device is a cooling cavity provided on the outer edge of the cooling zone of the air-tight cavity of the three-dimensional continuous glass molding device. There is a cooling liquid tank between the cooling cavity and the air-tight cavity. It has a cooling liquid inlet and a cooling liquid outlet. Because the mold is placed on the top of the carrier plate, it can only be placed on the bottom of the mold on the push plate. Because the upper end of the mold is not cooled at the same time, the cooling rate of the three-dimensional glass product in the mold is different due to the upper and lower ends , And the lack of damage caused by different stresses. The present invention proposes an improved design for this deficiency, so that the patent for a three-dimensional continuous molding device for molded glass is more perfect.

In view of the lack of conventional technology, the inventor of the present invention has accumulated many years of practical expertise in the design and manufacturing of precision ceramic technology industrial products. After continuous research and improvement, the research and development of the present invention has finally been successful and made public.

The reason is that the main object of the present invention is to provide a "cooling device for the continuous molding device for molded three-dimensional glass", which is applied to the cooling zone in the continuous molding device for molded three-dimensional glass products. A cooling cavity is provided at the outer edge of the cooling zone, and a cooling liquid tank is provided between the cooling cavity and the airtight cavity. The cooling liquid tank has a cooling liquid inlet and a cooling liquid outlet to cool the bottom of the mold placed on the carrier plate. The upper end of the cavity is further provided with an upper cooling device. The upper cooling device includes a pressure cylinder and two guide rods provided on the pressure cylinder side. A cooling block is provided on the head end of the pressure cylinder. A cooling fluid pipe is provided in the two guide rods on the pressure cylinder side. A cooling liquid tank is provided in the cooling block. The cooling pipe provided in the foregoing guide rod communicates with the cooling liquid tank in the cooling block. One end of the cooling liquid pipe in the two guiding rod is used as The cooling water inlet pipe is the other end as the cooling water outlet pipe. By pressing down the pressure cylinder, the cooling block is pressed against the upper end of the mold, which cools the upper end of the mold. It also cools the upper and lower ends of the mold at the same time. The cooling rate at the upper and lower ends is different, and the loss caused by different stresses is lost.
