Description of the Invention: [Technical Leadership of the Invention] The present invention mainly discloses a molding method for a plastic sheet used for a thin display, in particular, a method for forming a die by pressing a mold by heating a plate. The method of the piece. [Prior Art] *The thin display is covered with a U-shaped plate, which must have the characteristics of thin thickness and light weight. It can meet the weight reduction of thin display. The front thin display is used in notebook computers, notebook computers. The requirements for heavyweight are more stringent, and it is actively pursuing lightweight design. The traditional processing method of processing into a U-shaped shape is injection molding, and the processing method is to fold the plastic plate, but the molding after the injection molding is performed, and it takes time to wait for the emission mode to be limited by the thickness of the material. When the plastic injection molding force cannot be used, the thickness of the plastic plate is too thin. The thickness of the plastic plate is about 】 The thickness of the plastic plate is about 0. 使用 ° 0 〇' . However, the plastic sheet material will produce i should be Γ华令经^ bed:: the plastic pole pieces, in the ', and each easily breaks. IS] The plastic sheet parts of each type of punching material are easily damaged by external force collision or broken joints. The inviting people are not afraid of the prior art injection y force. There are defects in the Wei, but they cannot be satisfied with the use of thin type. = No " The method of forming the sheet, so the person who asked for the application was proposed in May and expected to overcome all the shortcomings of the above-mentioned conventional structure. SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to provide a U-shaped plastic sheet forming method for a thin display in view of the absence of the financial technology. The main object of the present invention is to 'slowly move toward the 4th-mold by the second mold and the positioning member, and the forming portion of the pressing head contacts the plate member through the passage, and the forming portion slowly pushes the plate member into the body. Forming the groove, the plate member is separated from the positioning member and enters the molding groove of the first mold, and the plate member is further bent into a U shape. A secondary object of the present invention is that the panel is heated prior to bending to raise the temperature of the jaw member which is heated to a temperature that exceeds the heat distortion temperature and is easily bent. Another object of the present invention is that the first mold is provided with a blowing pipe, and the month b is sufficient to blow the plate away from the first die. Other objects, advantages and novel features of the invention will be apparent from the description and appended claims. [Embodiment] The indenter 21 can extend the hole 32 of the positioning member 3Q, and the molding portion 22 can extend the molding groove through the land 33. The transverse yarn in the positioning member 30 at least-increases In the pipeline 34, the warming oil or other heat source is provided in the warming f road % to raise the temperature of the positioning member 3〇. Referring to Figure 4, a schematic view of the panel of the present invention placed on the positioning member is shown. The plate member 1 is a (four) flat plate, and the plate member 1 is placed in the receiving groove of the positioning member 3〇, the first mold 1G is not moved, and the first: mold (4) drives the positioning member _ toward the first mold 10 mobile. At this time, the ram 21 of the second mold 2 has not yet entered the bore 32, and the forming portion 22 of the ram 2 is located at the passage 33. M raw mold /, 1U Xing the second mold 2 〇 before pressing, need to heat 2 pieces 1 first, so that the hot oil through the warming line 23, 34 to raise the temperature of the second mold 0 and the piece 30 While raising the temperature of the panel, the panel 1 is heated to have a temperature exceeding the heat distortion temperature and is easily bent. Referring to Figures 5 and 6, the first and second molds of the present invention are not intended to be pressed. The first mold 10 and the second (fourth) first-TM first mold (four) are two=, 12 coincident with the accommodating groove portion 12_ accommodating groove of the positioning member 30. This grip is firstly moved by indirect heating to make it easy to face the positioning member (4), and the Chuan moves toward the edge-mold 1〇. The indenter is the channel 3_ the plate member 丨, the forming portion=^22 enters the forming #η心拉..., and pushes the plate member 1 into m3, so that the far-plate members are separated from the positioning 1355997 with 1G The forming groove 13' is bent in a U-shape at this time. The elastic member 26 is compressed by the second mold 2, so that the first mold and the position member 30 are attached to the second mold 20. Before the first mold 10 is separated from the second mold 20: = by the cooling line 14, the first mold is lowered, and the sheet is cooled to be formed. Figure. Figure 7' is an illustration of the separation of the first mold and the second mold of the present invention. 2 = the mold 20 is moved toward the end away from the first mold 1〇, and the second positioning member 3 is driven. The mold portion 22 that moves away from the first mold and the mold 2G indenter 21 is separated from the first material type II plate 13; the first mold 1G touches the second (four) 2 (3 separation, the i plate member W is located in the molding In the groove 13, at this time, the opening pipe 15' is blown to blow the plate member 丨, so that the plate member 1 is separated from the second figure A, which is a three-dimensional appearance of the formed plate member of the present invention. The u-shaped plate member 1 is slowly push-type, without the lack of the conventional rapid impact, and retains the structural strength and is not easily broken and damaged. The above description can be summarized that the present invention has the following advantages: The invention discloses a "u-shaped plastic sheet forming method for a thin display" "by a second mold and a positioning member slowly moving toward the first mold, the forming portion of the pressing head contacting the plate member through the passage, the forming portion is slow Pushing the board to listen to the person (4), let the board take off the _ positioning piece and enter the forming groove of the first mold, and further bend the board to be U-shaped. i S] 1355997 2. The invention "Improve _ display The method: the plate has been heated before bending, and the plate is raised by the == piece ^ heating The temperature is higher than the heat distortion temperature and is easily bent. Also / 3. The invention is used in the "thin-type method", and the method for forming a plastic sheet of a type of plastic sheet is used to remove the first mold through the sheet member. The only part of the board is only the preferred embodiment of the present invention. When it is not possible to limit the scope of the forest, the replacement of the change of the riding value or the patent application according to the present invention. The equal variation of the scope is still covered by the patent of the present invention.
