Description

Support device for gas-tight continuous hot press forming device

In particular, the present invention is an improved designer of a support device for a gas-tight continuous atmosphere sintering molding apparatus for a hot press molding product, which has a better support effect of the carrier plate and can effectively avoid breakage or deformation of the carrier plate.

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.

Applicant previously proposed the approved M536234 "Airtight Molded Stereoscopic Glass Continuous Forming Device", which is a new design for continuous molding of molded three-dimensional glass products. It is mainly composed of furnace body, closed type, and external body of furnace. The exchange system is provided at the end, and the airtight cavity is arranged inside the furnace body; the exchange system is arranged at the two ends of the furnace body, and the outer conveying lane is arranged between the two end exchange systems of the furnace body. Each of the exchange systems includes an inner airtight door disposed on the side of the furnace body and an airtight door disposed outside the outer conveyor side, and an airtight space is formed between the inner airtight door and the outer airtight door, and the displacement device is provided with the carrier plate. Pushing or removing the furnace body; the airtight chamber is disposed inside the furnace body, and includes an airtight cavity, the airtight cavity has an inner conveying lane, and the inner conveying channel is connected with the airtight door of the two-end exchange system of the furnace body, and is provided There is a slide rail, which serves as a track for moving the carrier plate. The airtight chamber is airtight and introduces protective gas, and has a temperature rising zone according to the process, a high temperature forming zone and a cooling zone, and a heating zone and a high temperature forming zone. There is at least one layer of thermal insulation, and a thermal field is formed in the center of the thermal insulation layer. The heating field is provided with a heating element according to the temperature required by the process program, the cooling zone has a cooling device, the high pressure forming zone is provided with a pressing system, and the outer conveying channel is provided. The two-end exchange system of the furnace body is connected; the pressurization system is mainly composed of a pressure cylinder, a pressurizing shaft and a pressurizing column; in the present invention, the flat glass to be formed is placed in the mold forming surface, and the mold is placed on the carrier board. The carrier board enters the airtight chamber through the exchange system and is heated The preheating of the zone and the high temperature of the high temperature forming zone soften the in-mold glass and are formed by the pressurization of the pressurizing system, and then cooled by the cooling zone, sent out of the furnace body through the exchange system, and then demolded. It also achieves the effect of continuous, high-efficiency and high-quality molded three-dimensional glass.

In the previous case, it is in the high temperature forming zone of the airtight cavity, and further comprises a lower pressing plate, and a supporting device composed of a supporting column and an adjusting device is arranged below the lower pressing plate, and when the pressing system is actuated, the supporting column top can be supported The platen is pressed to effectively support the carrier plate to avoid breakage. When the level or angle of the lower platen is deviated, the adjustment device can be used to adjust the top of the support column against the lower platen to the correct horizontal position to effectively support the carrier plate and avoid breakage. It can be seen that the supporting device is supported by the top of the supporting column against the lower pressing plate to support the carrier plate. Since the contact surface between the supporting column and the lower pressing plate has only the end surface contacting the supporting column, the supporting area is limited, and after a period of use, the deformation of the lower pressing plate is caused. Warping, unable to effectively support the carrier plate, for its lack, it is necessary to propose a better design for the supporting device of the molding device, so that The patent for continuous hot press forming equipment is more perfect.

After continuous research and improvement, the research and development 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 "support device for a gas-tight continuous hot press forming device" which is disposed in a high temperature forming zone of a hermetic cavity of a gas-tight continuous hot press forming device.
