Abstract: A positioning mechanism (24) for use in a mold structure (100) to position a film (30) within the mold structure is provided. The mold structure includes a core mold portion (10) and a cavity mold portion (20) mating with the core mold portion. The core mold portion includes a core plate (12) and a core insert (14) formed on the plate. The cavity mold portion includes a positioning mechanism having a moveable cavity insert (242) and an elastic member (244) for outwardly biasing the cavity insert.

Abstract: A lens cover slidably mounted to a lens comprises a main body and two guide plates protruding from opposite sides of the main body. Each guide plate has a plurality of contact portions. Each contact portion includes a plurality of projection strips protruding from a surface thereof and facing the lens.

Abstract: A sliding mechanism (100) used in a portable electronic device (200) is provided. The sliding mechanism includes a sliding member (12). The sliding member includes a cover portion (121) and two sliding rails (123). The cover portion is made of a plastic material that can be electro-plated. The sliding rails are made of another plastic material that has a low coefficient of friction.

Abstract: A sliding-type mechanism for use in a portable electronic device is provided. In one embodiment, the sliding-type mechanism includes a base plate, a slidable plate and a linkage module. The slidable plate is slidably connected to the base plate. The linkage module is positioned between the base plate and the slidable plate and connects the base plate and the slidable plate. The linkage module includes a first and second torsion springs and each torsion spring includes a plurality of spring coils. The first and second torsion springs are configured to drive the slidable plate to slide along the base plate when the slidable plate moves a predetermined range along the base plate.
