Abstract: A mold assembly for fabricating an optical fiber connector includes a male mold and a first sliding block. The male mold includes a base, a first locating flange, and a second locating flange. The first locating flange and the second locating flange are spaced apart from each other. The first locating flange, the second locating flange, and the base cooperatively define a first receiving opening. A front surface of the first sliding block defines two first holes for forming two locating poles of the lens assembly. A shape and a size of the first sliding block respectively correspond to a shape and size of the first receiving opening to make the first sliding block be precisely located in the first receiving opening.

Abstract: A mold assembly for manufacturing light guide plates of different sizes without being dismantled includes a male mold with base, a number of pairs of molding blocks and driving blocks, together with two bolts, and an injecting block. The pairs of molding and driving blocks, and the driving block and two bolts are received in the male mold base. The driving block is movably connected to the molding block by the two bolts. A position of the molding block relative to the driving block is adjusted by screwing at least one of the two bolts. An injecting block is positioned in the male mold base and surrounds a male mold chamber with the molding block.

Abstract: A mold assembly includes a male mold, a female mold, and a driving unit. The male mold includes a stationary member, a moveable member defining through holes, and mold cores fixed on the stationary member and received in the respective through holes. The female mold covers the moveable member. The female mold defines recesses aligned with and communicating with the respective through holes. The moveable member, the female mold and the mold cores cooperatively form mold cavities at the through holes. The driving unit is fixed on the stationary member and supports the moveable member. The driving unit is configured for driving the moveable member to move upward or downward along the mold cores relative to the stationary member.

Abstract: An LED package includes a lens, an LED chip securely received and engaged in the lens, and a base with an electrode assembly thereon. A bottom surface of the LED chip is bare.
