Description

Pressurizing device of airtight continuous hot pressing forming device

technical field

The utility model provides a hot pressing forming device, in particular to a pressurizing device of an airtight continuous hot pressing forming device suitable for manufacturing three-dimensional products.

Background technique

Thermoforming is a processing method of polymer materials. It mainly puts a material with a certain thickness in a mold, heats the mold or the environment, softens the material and covers the surface of the mold, and then squeezes it with a machine, and then solidifies after the cooling stage. , you can get thermoformed products.

The material for thermoforming is glass, for example, because glass has high light transmission characteristics, so display devices (such as mobile phones, watches and other electronic products) often choose it as the shell of the window part. You can see that the surface of handheld electronic products 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 a seam will be 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 glass casings of electronic products.

The flat glass case is relatively easy to manufacture, but the glass case with a three-dimensional shape is relatively difficult to manufacture. At present, there are generally two methods for manufacturing a three-dimensional glass case: the first method is: manufacturing a plurality of flat glass units, and then forming a three-dimensional glass case by pasting the edges. The second method is to manufacture a rectangular parallelepiped glass with a certain thickness, and then grind the rectangular parallelepiped glass multiple 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 arrange the flat glass material between an upper mold and a lower mold, and then heat the upper mold, Lower the mold and the glass material to soften the glass material. When the above-mentioned 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, so as to produce the corresponding molded glass . China Taiwan Patent Announcement No. M452174 "Molding Equipment for Manufacturing Molded Glass" (announcement date is May 01, 2013), which includes a female mold part, a first male mold part, and a second male mold parts, a supporting mandrel and a pressing bar. The first male mold part is arranged on the female mold part in an openable and closable manner, and the second male mold part is arranged between the female mold part and the first male mold part. The supporting ejector rod is passed through the female mold part, and the supporting ejector rod is used to push against the second male mold part, so as to support the second male mold part and the first male mold part to be clamped together A molded glass. The pressing rod is arranged on one side of the first male mold part, and the pressing rod is used to press down on 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 clamping position for molding the molded glass.

The applicant previously proposed the approved Taiwan No. M536234 "Airtight Molded Three-dimensional Glass Continuous Molding Device", which is a new design for the continuous molding device designed for molded three-dimensional glass products. It is mainly composed of a furnace body, which is airtight. There is an exchange system at the two ends, and an airtight cavity is provided inside the furnace body; the exchange system is located at both ends of the furnace body, and an external conveying channel is provided between the exchange systems at the two ends of the furnace body, and each exchange system includes an airtight chamber located on the side of the furnace body The inner airtight door and the outer airtight door located on the side of the outer conveying path form an airtight space between the inner airtight door and the outer airtight door, and a displacement device is provided to push the carrier plate into or out of the furnace body; the airtight chamber , located inside the furnace body, including an airtight chamber, which has an inner conveying channel, which is connected to the inner airtight door of the exchange system at the two ends of the furnace body, and is equipped with slide rails to serve as a carrier for moving track, the airtight cavity is airtight, and the protective gas is introduced, and there are heating zone according to the process), high temperature forming zone and cooling zone, at least one layer of heat insulation layer is provided in the heating zone and high temperature forming zone, and the break A heat field is formed in the center of the heat layer, and a heating element is installed in the heat field according to the temperature required by the process procedure. The cooling area is equipped with a cooling device, and the high-pressure forming area is equipped with a pressurization system; the outer conveyor is connected to the exchange system at the two ends of the furnace body; The pressure system is mainly composed of a pressure cylinder, a pressure shaft and a pressure column; in the utility model constituted in this way, the flat glass to be formed is placed on the molding surface of the mould, the mold is placed on the carrier plate, and the carrier plate enters the airtight through the exchange system. The cavity is preheated in the heating zone and the high temperature in the high-temperature forming zone softens the glass in the mold and is formed by pressing the pressure system. After being cooled in the cooling zone, it is sent out of the furnace body through the exchange system, and then Formed by demoulding, it can indeed achieve the effect of continuous, high-efficiency and high-quality molding of three-dimensional glass.

As mentioned above, the existing pressurization system is mainly composed of a pressure cylinder, a pressurization shaft and a pressurization column. Since the pressure cylinder cannot accurately control the speed, pressure intensity and precise positioning of the pressurization column on the hot pressing mold Displacement distance, and the pressurization system is set at the center of each set of hot-pressing molds, and a single pressurization system is used to apply pressure to the center of the relative hot-pressing mold. This means that when the size of the three-dimensional glass to be hot-pressed is small, the flatness of the molded three-dimensional glass can still be maintained. The pressure applied by the pressurization system is concentrated in the center of the hot-pressing mold, which may easily cause warping, skewing and other unevenness in the four corners of the molded three-dimensional glass product, resulting in a very low yield rate of the molded three-dimensional glass hot-pressing molding. This is the biggest defect in the current prior art, and this deficiency is a difficult problem to be overcome urgently in the industry.
