Improvement of heating device for three-dimensional molded glass continuous forming device

The invention belongs to the technical field of heating devices, and particularly relates to a novel design of a heating device for a three-dimensional molded glass continuous forming device, which has less heat loss and good conduction, and is suitable for continuous molding of high-temperature stereo-molded glass.

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 arrange a flat glass material between an upper mold and a lower mold, and then heat the upper mold, the lower mold, and the glass material to make the glass material. soften. 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.

The 3D three-dimensional molded glass forming machine is formed by the hot press forming technology, and the heating device directly heats the mold by using a heating device, which comprises a heating device disposed on the lower end of the pressing device and a heating device disposed below the lower portion, which is conventionally used. The heating device is shown in Fig. 1. It is mainly fixed by screws (A), heating block (B) and heating plate (C). The heating block (B) is provided with an appropriate quantity.

However, such conventional heating devices have a lack of heat conduction loss due to the combined heating block (B) and heating plate (C) structure. Lost, and the rod-type heating tube (E) can not provide enough heating temperature to the mold. In today's glass, the softening temperature is getting higher and higher (especially the softening temperature of the aluminum-containing glass is high), which can not meet the needs of the industry. Missing. This is the biggest lack of current conventional technology, and this lack is a difficult problem to be overcome in the industry.

In view of the lack of the aforementioned conventional technology, the creator of this case has accumulated many years of experience in the design and manufacture of precision ceramics technology industrial products. After continuous research and improvement, the creation of this creation has been successful and made known to the world.

The reason is that the main purpose of this creation is to provide a "heating device improvement for a three-dimensional molded glass continuous forming device", which is specially designed for the heating device structure of the three-dimensional die-making glass continuous forming device. The heating device is made of heat conduction material. The integrally formed heating block is formed with an appropriate number of slots for arranging the heating element. Since the heating block is integrally formed, there is no conduction heat loss, and heat conduction is good, and is suitable for continuous molding of higher temperature stereo-molding glass.

The heating block of the present invention has a groove rail on the heating surface as a track for moving the mold, and the two ends of the groove rail have a large open end, so that the mold can be smoothly pushed into the fixed point.

In the above heating block, the heating element is mainly provided with an electric heating element and a protection tube covering the outer edge of the electric heating element. The heating element is exposed at the open end of the protection tube and forms a terminal, and the protection tube is The two sides of the open end are fixedly closed by a fixing member, and the open end of the protective tube is provided with a gas seal sealing layer to form a gas seal state to provide a high temperature to heat the heating block.
