Abstract: An endoscope distal end frame includes: a holder including a first through hole, the holder being a primary molding made of a colored resin; and a distal end part including a second through hole that is concentric with the first through hole, the distal end part being a secondary molding made of a transparent resin layered on the holder. The first through hole has a diameter larger than a diameter of the second through hole.

Abstract: A first lens surface includes a first optically effective surface, and a convexly first engagement portion which protrudes toward a second lens side from an optical extended surface formed with the same curvature as the first optically effective surface as a position substantially corresponding to an outer edge of the first optically effective surface. A second lens surface includes a second optically effective surface larger in diameter than the first optically effective surface, and a convexly second engagement portion, which is provided outside the second optically effective surface, which protrudes toward a first lens side, which is engaged with the first engagement portion, which positions the first lens and the second lens.

Abstract: A two-color molding die includes: a fixed primary die; a fixed secondary die; and a movable die. The fixed primary die includes a first concave portion. The movable die includes a second concave portion facing the first concave portion, and a core pin that protrudes from a base end surface of the second concave portion toward a base end surface of the first concave portion to form a tubular primary molding cavity between the core pin and the first concave portion and the second concave portion. The fixed secondary die includes a third concave portion configured to form a concave secondary molding cavity.

Abstract: An injection molding method includes a supply step of simultaneously supplying molten resins to a cavity portion from two gate portions and an associating step of associating the molten resins supplied from the two gate portions in a central part of the cavity portion. The supply step supplies the molten resins to the cavity portion from the two gate portions which substantially face each other around the cavity portion. The associating step includes at least one of a first step in the supply step of simultaneously starting the supply of the molten resins to the cavity portion from the two gate portions, and a second step in the supply step of simultaneously starting the injection of the molten resins into the cavity portion from the two gate portions at the same injection rate.
Abstract translation: 注射成型方法包括从两个栅极部分同时将熔融树脂供应到空腔部分的供给步骤以及在空腔部分的中心部分中将从两个栅极部分供应的熔融树脂相关联的缔合步骤。 供给步骤将熔融树脂从基本上围绕空腔部分彼此面对的两个门部供应到空腔部分。 关联步骤包括供应步骤中的第一步骤中的至少一个步骤，同时开始从两个浇口部分向空腔部分供应熔融树脂;以及供给步骤中的第二步骤，同时开始熔融 树脂以相同的注射速率从两个栅极部分进入空腔部分。
