Description

Technical Field

[0001] The utility model belongs to the technical field of hot pressing and forming, in particular to a pressurizing device of an airtight continuous hot pressing and forming device suitable for molding three-dimensional products. Background Art

[0002] Thermoforming is a method of processing polymer materials. It mainly involves placing a material of a certain thickness in a mold, heating the mold or the environment to soften the material and cover the mold surface, and then squeezing it with a machine. After the cooling stage and solidification, a thermoformed product can be obtained.

[0003] For example, glass is a material for hot pressing. Because glass has a high light transmittance, it is often used as the shell of the window part of display devices (such as mobile phones, watches and other electronic products). You can see that handheld electronic products are usually provided with a glass shell on the surface to protect the display module inside the product. At present, most of the glass shells 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 retained 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 gradually been used in the glass shell of electronic products.

[0004] Flat glass shells are easier to manufacture, while glass shells with three-dimensional shapes are more difficult to manufacture. At present, there are usually two methods for manufacturing glass shells with three-dimensional shapes: the first is to manufacture multiple flat glass units, and then form a glass shell with a three-dimensional shape by gluing the edges. The second is to manufacture a rectangular glass of a certain thickness, and then grind the rectangular glass several times to form a three-dimensional shape with multiple sides. However, both of the above 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, the better way is to place the 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 soften the glass material. When the above 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, thereby producing the corresponding molded glass. As disclosed in Taiwan Patent Announcement No. M452174, "Forming Equipment for Manufacturing Molded Glass" (referenced to Taiwan Patent Announcement Information with the announcement date of May 1, 2013), it includes a female mold piece, a first male mold piece, a second male mold piece, a supporting push rod and a pressure rod. The first male mold piece is arranged on the female mold piece in an openable and closable manner, and the second male mold piece is arranged between the female mold piece and the first male mold piece. The supporting push rod is passed through the female mold piece, and the supporting push rod is used to push the second male mold piece, thereby supporting the second male mold piece and the first male mold piece to jointly clamp a molded glass. The pressure rod is arranged on one side of the first male mold piece, and the pressure rod is used to press down on the first male mold piece, so that the first male mold piece and the second male mold piece move to a mold closing position relative to the female mold piece, thereby forming the molded glass.

[0005] The applicant previously proposed and obtained Taiwan Patent No. M536234, "Airtight Molded Three-Dimensional Glass Continuous Forming Device", which is a brand-new design of continuous forming device designed for molded three-dimensional glass products. It is mainly composed of a furnace body, which is a closed type, with exchange systems at both ends of the outside of the furnace body, and an airtight cavity inside the furnace body; the exchange system is arranged at both ends of the furnace body, and an external conveying channel is arranged between the exchange systems at both ends of the furnace body. Each exchange system includes an inner airtight door arranged on the side of the furnace body and an outer airtight door arranged on the side of the external conveying channel. An airtight space is formed between the inner airtight door and the outer airtight door, and a displacement device is provided to push the carrier into or out of the furnace body; the airtight cavity is arranged inside the furnace body, including an airtight cavity, and an inner conveying channel is provided in the airtight cavity. The inner conveying channel connects the inner airtight doors of the exchange system at both ends of the furnace body, and is provided with a slide rail to serve as a track for the movement of the carrier. The airtight cavity is airtight and A protective gas is introduced, and the temperature rising zone, high temperature forming zone and cooling zone are divided according to the process. At least one thermal insulation layer is provided in the temperature rising zone and the high temperature forming zone, and a heat field is formed in the center of the thermal insulation layer. A heating component with a temperature required by the process program is provided in the heat field. The cooling zone has a cooling device, and the high temperature forming zone has a pressurizing system; an external conveying channel connects the exchange system at both ends of the furnace body; the pressurizing system is mainly composed of a pressure cylinder, a pressurizing shaft and a pressurizing column; in the present invention constructed in this way, the flat glass to be formed is placed on the forming surface of the mold, and the mold is placed on the carrier, and the carrier enters the airtight cavity through the exchange system, and is preheated in the temperature rising zone and the high temperature in the high temperature forming zone to soften the glass in the mold, and is formed by the pressurization of the pressurizing system, and then is cooled in the cooling zone, and then sent out of the furnace body through the exchange system, and then demolded, which can also achieve the effect of continuous, high-efficiency and high-quality molding of three-dimensional glass. However, as mentioned above, the known pressurizing system is mainly composed of a pressurizing cylinder, a pressurizing shaft and a pressurizing column. Since the pressurizing cylinder cannot accurately control the speed, pressure intensity and precise positioning displacement distance of the pressurizing column applied to the hot pressing mold, and the pressurizing system is set at the center of each set of hot pressing molds, a single pressurizing system is used to apply pressure to the center of the hot pressing mold. This can maintain the flatness of the molded three-dimensional glass when the size of the hot pressing molded three-dimensional glass is small, but for molded three-dimensional glass products with larger sizes, because the pressure applied by the pressurizing system is concentrated in the center of the hot pressing mold, it is easy to cause the four corners of the molded three-dimensional glass product to be warped, skewed and other uneven conditions, resulting in an extremely low yield rate of hot pressing molding of the molded three-dimensional glass.

[0006] In view of the above-mentioned deficiencies, the applicant has proposed a pressurizing device for a continuous hot pressing forming device, which mainly corresponds to a plurality of hot pressing molds and is relatively provided with a plurality of groups, each group having four units of pressurizing components, each unit of the pressurizing components includes a servo motor, the lower end of the servo motor is connected to a pressure control device, the lower end of the pressure control device is connected to a water-cooled pressurizing shaft, and the lower end of the water-cooled pressurizing shaft is connected to a pressurizing column. The above-mentioned pressurizing device is arranged in the hot pressing forming area of ​​the airtight continuous hot pressing forming device, and the hot pressing forming area includes a water-cooled airtight furnace, and an airtight cavity is arranged in the water-cooled airtight furnace, the airtight cavity is airtight, and a protective gas is introduced, and a thermal insulation layer and a thermal insulation reflective plate are provided, and the thermal insulation layer A heat field is formed in the center, and a heating component with a temperature required by the process sequence and a supporting platen are provided in the heat field. A hot pressing mold is placed on the supporting platen. The servo motor and pressure control device of the aforementioned pressurizing device are arranged above a water-cooled airtight furnace chamber. The water-cooled airtight furnace chamber is provided with an airtight shaft seal for a water-cooled pressurizing shaft to pass through. The pressurizing column is passed through the heat field, and the four pressurizing columns of the aforementioned four-unit pressurizing components are arranged above the four corners of the hot pressing mold. By means of each group of four-unit pressurizing components, precise pressure is applied to the four corners of the pressure-bearing surface above the hot pressing mold, so that the various parts of the three-dimensional product to be hot-pressed in the hot pressing mold are evenly stressed (referenced by Taiwan Patent No. I685472).

[0007] However, although the aforementioned Taiwan Patent No. I685472 can overcome the defect that "because the pressure applied by the pressurizing system is concentrated in the center of the hot pressing mold, it is easy to cause the four corners of the molded three-dimensional glass product to be warped, skewed, and other uneven conditions, resulting in an extremely low yield rate of hot pressing molding of the molded three-dimensional glass", for the current molded three-dimensional glass products (such as mobile phones, tablet computers, etc.) with increasingly larger sizes and rectangular designs, their increasingly longer sides, if only four pressurizing columns are set above the four corners of the hot pressing mold, and the pressurizing components of each group of four units are used to accurately apply pressure to the four corners of the upper pressure surface of the hot pressing mold, it will not be possible to make the unpressurized part in the middle of the three-dimensional product to be hot-pressed in the hot pressing mold uniformly stressed, especially when the three-dimensional product to be hot-pressed in the mold is thinner, because the pressure applied by the pressurizing system is concentrated in the four corners of the hot pressing mold, it is possible to cause the unpressurized part in the middle of the molded three-dimensional glass product to be convex and uneven, thereby reducing the yield rate of hot pressing molding of the molded three-dimensional glass. This is the biggest shortcoming of the currently known technology, and this shortcoming has become a difficult problem that the industry needs to overcome urgently. Utility Model Content
