摘要： PROBLEM TO BE SOLVED: To prevent the positional precision of a guide pin hole from being deteriorated due to the movement of a sleeve upon resin injection.
SOLUTION: In the molding method of optical ferrule, an optical ferrule made by forming the guide pin hole for the positioning by means of insert molding of a sleeve 9 is molded with resin. Therein, a die comprising upper die, lower die 12 and middle die is used. The middle die 13 has a sleeve support pin 17. Protruded parts 22 which are arranged proximately with a little gap between the under surface of the sleeve 9 supported by the support pin 17 and the protruded parts are disposed on the lower die 12. The sleeve 9 is supported in such a manner as to be hung by the support pin 17 as shown in Fig.(1) because of a clearance with the support pin 17. Therein, the upper surface of the protruded part 22 is opposed to the lower surface of the sleeve 9 with a narrow gap H. When resin is injected into the die, a pressure (resin pressure) due to the resin in a fluidized state is applied to the sleeve 9, however, the resin does not infiltrate to the narrow gap H on the lower surface side of the sleeve 9. As shown in Fig. (2), the resin pressure is not applied to the lower surface side of the sleeve 9, a vertically downward force F is applied to the sleeve 9 as a whole and, therefore, the sleeve 9 does not move when the resin is injected.

摘要翻译：要解决的问题：为了防止导向销孔的位置精度由于树脂注入时套筒的移动而劣化。解决方案：在光学套圈的成型方法中，通过用套筒9的嵌入成型形成用于定位的引导销孔制成的光学套圈用树脂模制。其中，使用包括上模，下模12和中模的模具。中间模具13具有套筒支撑销17.突出部分22布置在下模具12上，该支撑部分22靠近由支撑销17支撑的套筒9的下表面和突出部分之间的小间隙布置。套筒如图1所示，由于与支撑销17的间隙，支撑件9被支撑在支撑销17上。其中，突出部分22的上表面与下表面套筒9具有窄的间隙H.当将树脂注射到模具中时，由于树脂处于流化状态而导致的压力（树脂压力）被施加到套筒9上，然而，树脂不会渗透到窄间隙 H在套筒9的下表面侧。（2）中，不向套筒9的下表面侧施加树脂压力，因此整体上向套筒9施加垂直向下的力F，因此当注入树脂时，套筒9不移动。版权所有（C）2005，JPO＆NCIPI
