摘要： PROBLEM TO BE SOLVED: To provide a manufacturing technique of glass with a molding capable of suppressing the occurrence of a weldline and flash.
SOLUTION: An attracting holder comprising a permanent magnet, an electromagnet, etc. is embedded in a mold for a molding to attract a metal molding constituting a part of the skin of the resin molding. By this method, as shown in Fig.6(b), the metal molding 36 is strongly fixed to a fixed mold 20 by the synthetic action of the attraction force of the attracting holder 24 and the pressing action of a molten resin 39. Accordingly, the metal molding 36 is not shifted or floated by the flow or pressure of the molten resin 39. Since the metal molding 36 is closely brought into contact with the fixed mold 20, there is no anxiety that the molten resin 39 is turned to the area under the metal mold 36.

摘要翻译：要解决的问题：提供具有能够抑制焊接线的发生和闪光的成型的玻璃的制造技术。解决方案：将包括永磁体，电磁体等的吸引支架嵌入到用于模制的模具中，以吸引构成树脂模制品的一部分皮肤的金属模制品。通过该方法，如图6（b）所示，通过吸引保持器24的吸引力和熔融树脂39的挤压作用的合成作用，将金属模制件36牢固地固定在固定模具20上。因此金属模制件36不会被熔融树脂39的流动或压力移动或浮动。由于金属模制件36紧密地与固定模具20接触，因此不会使熔融树脂39转向金属模具36下的区域。版权所有（C）2007，JPO＆INPIT

摘要： PURPOSE:To prevent any damage on the surface of a mold by injecting resin material for forming a surface portion into a cavity formed between a pair of molds, and then injecting other resin material for forming a backup portion into another cavity formed between one of the above-mentioned pair of molds and another mold. CONSTITUTION:In molding a window mold, first of all, first resin material 4 is injected into a cavity 3 formed by means of a first upper mold 1 and a lower mold 2. Next, a surface portion 5 is formed by hardening the first resin material 4, and then, the first upper mold 1 is removed with the surface portion 5 kept on the lower mold 2 side, and further, a plate glass G is set on the lower mold 2. In addition, a second upper mold 6 is fastened onto the lower mold 2 so that the plate glass G is held therebetween. Successively, second resin material is injected into a cavity 7 formed by means of the surface portion 5 and the second upper mold 6, and as well, a backup portion 9 is formed by hardening the second resin material. Therefore, the backup portion 9 and the surface portion 5 are respectively formed on the margin of the plate glass G.

摘要： PURPOSE:To enhance manufacturing efficiency by preparing two lower molds with respect to one upper mold and setting new plate glass to one lower mold while forming a molding between the other lower mold and the upper mold to prepare for the next molding. CONSTITUTION:An upper mold 6 and a lower mold 9a are clamped and a cavity 10 to which the peripheral edge part of plate glass G is faced is formed between both molds. The plate glass G is held by the clampers 11 composed of an elastic material provided to the molds to be prevented from damage. Subsequently, polyvinyl chloride or a reaction type mixed raw material resin is injected in the cavity to be cured for a predetermined time and the upper mold 6 is subsequently raised and slide tables 8a, 8b are moved to the right in a drawing and the lower mold 9a is moved to the delivery position outside a mold clamping machine 2 to deliver the plate glass G as a product having a molding formed along the peripheral edge thereof while a lower mold 9b is moved to a clamping position and the upper mold 6 is allowed to fall to perform mold clamping. By repeating this operation, window glass with a molding is continuously formed.

摘要： PURPOSE:To permit a metallic member to be set easily, by integrally bonding the metallic member such as a film, a tape or the like made by forming a metal film to at least a part of outside of a molding integrally formed on the circumferential edge of a window member. CONSTITUTION:When a molding 13 is to be integrally formed on the circumferential edge of a window frame 6, the circumferential edge of the window member 6 is placed between the recessed portions 3, 4 of metal molds 1, 2 while they are opened. Then, a metallic member is gripped between an end of a porous member 11 having permeability and the metal mold 2 and between the packing 7 of the metal mold 1 and the window member 6 and the molds 1, 2 are closed. Next, the circumferential edge of the window member 6 is confronted with the cavity 5 of the metal molds 1, 2 and the end of the metallic member 12 is gripped before it is adsorbed and fixed on the surface of the porous member 11 by operating a vacuum suction unit connected to a suction hole 9. After that, melted resin is supplied into the cavity 5 for integrally forming the molding 13 on the window frame 6.
