Description

Transfer board

In addition to the continuous, high-efficiency and high-quality hot-pressed products, the new design of the transfer board for the air-tight continuous atmosphere sintering hot-pressing equipment for hot-pressed products has better heating and Cooling rate.

Press, hot press forming is a method of processing polymer materials, mainly by placing a material with a certain thickness in a mold, heating the mold or the environment, softening the material to cover the surface of the mold, and then pressing the machine through the cooling stage. After curing, a hot formed product can be obtained.

For hot-pressed materials, for example, glass has high light transmission characteristics, so display devices (such as mobile phones, watches and other electronic products) are selected as the outer casing of the window. 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 casing having a three-dimensional shape: the first one is: manufacturing a plurality of flat glass units, and then forming a standing by sticking edges Body shaped glass housing. 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. Pieces, lower molds and glass materials 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. However, it is still unable to meet the industry's need for continuous and rapid manufacturing of high-quality molded three-dimensional glass.

Please refer to FIG. 1 , which is a side view of a conventional upper and lower heating type molding apparatus, which mainly comprises an upper heating plate (A), a bottom heating plate (B) and a displacement mechanism (C), and a mold (D) system. Placed on the bottom heating plate (B), the displacement mold (D) is moved by the displacement mechanism (C), although the mold (D) and the bottom heating plate (B) are contact heating, and the displacement mechanism (C) is Located in the furnace, easy to change due to high temperature in the furnace Shape or damage, missing for it.
