Title (EN) INJECTION MOULD AND LIGHT GUIDE PLATE MANUFACTURING DEVICE
(FR) MOULE D'INJECTION ET DISPOSITIF DE FABRICATION DE PLAQUE DE GUIDAGE DE LUMIÈRE
(ZH) 注塑模具及导光板的制备装置
Abstract:
(EN) Provided are an injection mould and a light guide plate manufacturing device. The injection mould comprises a male mould (100) and a female mould (200), and the male mould (100) and the female mould (200) operate cooperatively together to define a moulding cavity (101) for forming a sheet-like part (300). A blowing device (170) is provided in the male mould (100), and the blowing device (170) is used for blowing a gas having a preset pressure to a bottom surface of the sheet-like part (300) formed in the moulding cavity (101); so as to overcome a vacuum adsorption force between the bottom surface of the sheet-like part (300) and the bottom surface of the moulding cavity (101), thereby separating the sheet-like part (300) from the male mould (100). Therefore, the sheet-like part (300) can be demoulded smoothly, and the sheet-like part (300) can be effectively prevented from severe warping during the demoulding process, safeguarding the quality of the sheet-like part (300).
(FR) L'invention concerne un moule d'injection et un dispositif de fabrication de plaque de guidage de lumière. Le moule d'injection comprend un moule mâle (100) et un moule femelle (200) et le moule mâle (100) et le moule femelle (200) fonctionnent en coopération l'un avec l'autre pour définir une cavité de moulage (101) pour former une pièce (300) de type feuille. Un dispositif de soufflage (170) est situé dans le moule mâle (100) et le dispositif de soufflage (170) est utilisé pour souffler un gaz présentant une pression préétablie au niveau d'une surface inférieure de la pièce (300) de type feuille formée dans la cavité de moulage (101) de manière à surmonter une force d'adsorption sous vide entre la surface inférieure de la pièce (300) de type feuille et la surface inférieure de la cavité de moulage (101), ce qui permet ainsi de séparer la pièce (300) de type feuille du moule mâle (100). Par conséquent, la pièce (300) de type feuille peut être démoulée sans à-coups et un gauchissement sérieux de la pièce (300) de type feuille peut être évité de façon efficace pendant le procédé de démoulage, ce qui protège la qualité de la pièce (300) de type feuille.
(ZH) 一种注塑模具和一种导光板的制备装置,包括公模(100)和母模(200),公模(100)与母模(200)配合,共同限定用于形成薄板状部件(300)的成型腔(101)。在公模(100)中设置有吹气装置(170),吹气装置(170)用于向形成在成型腔(101)中的薄板状部件(300)的底面吹送具有预定压力的气体,以克服薄板状部件(300)的底面与成型腔(101)的底面之间的真空吸附力,从而使薄板状部件(300)与公模(100)分离。因此,能够使薄板状部件(300)顺利脱模,并且能够有效防止薄板状部件(300)在脱模的过程中出现较大翘曲,保证了薄板状部件(300)的质量。
