Abstract: A molding machine includes a machine table, a mold unit and a pair of positioning units. The mold unit includes first and second molds mounted on the machine table and movable between a mold-closing position and a mold-opening position. The first and second molds abut against each other in the mold-closing position. Each of the positioning units includes a first positioner connected to the first mold, and a second positioner connected to the second mold. When the first and second molds are in the mold-closing position, the first and second positioners are operable to move to a locked state, where the first positioner is held by the second positioner to restrain the first and second molds from deforming away from each other.

Abstract: A molding machine includes two holding arms mounted on a base unit, connected respectively to two molds, and operable to move the molds between a mold closing state and a mold opened state. The molding machine further includes an adjusting seat mounted on the base unit and movable relative to a threaded shaft that is rotated by a power supply, a swing arm connected pivotally to the adjusting seat, a linkage unit having opposite end parts that are connected pivotally and respectively to a pivot portion of the swing arm and one of the holding arms, and another linkage unit having opposite end parts that are connected pivotally and respectively to another pivot portion of the swing arm and the other one of the holding arms. The swing arm is swingable through the movement of the adjusting seat so as to swing the holding arms by virtue of the linkage units.

Abstract: An exemplary backlight module (1) includes a light guide plate (10) and at least one light source assembly (16). Each of the light source assembly includes a plurality of point light sources (163) and a light source holder (160). The light source holder accommodates the point light sources and an end portion (12) of the light guide plate, with a distance between the end portion and the point light sources.

Abstract: An electric hollow molding machine includes left and right molds, two operating arms connected respectively to the molds, a drive shaft unit driven by a power source to rotate, a movable seat including two first mounting sections to mount pivotally one operating arm to the movable seat, a threaded rod rotated by the drive shaft unit, a sleeve moved leftward or rightward by the threaded rod, first and second transmission seats movable along with the sleeve, at least one connecting shaft having one end connected to the second transmission seat, and a second mounting section connected to another end of the connecting shaft to mount pivotally the other operating arm to the connecting shaft. When the movable seat and the second transmission seat move telescopically relative to each other, the operating arms move the molds toward or away from each other to a mold closing or opening position.

Abstract: Molding machines and methods of performing molding processes are described. One embodiment includes a base, a carriage disposed movably on the base, a first mold secured immovably to the carriage, a second mold disposed slidably on the carriage, a driving unit for moving the second mold on the carriage and toward and away from the first mold, a push shaft inserted telescopically into a pressure cylinder and pushing the second mold against the first mold, a synchronous transmission unit for moving said carriage synchronously with the second mold so that the first mold is moved to said second mold, and a pressure booster including a booster tube, and a telescopic booster rod extendable into the booster tube to transfer pressure in the booster tube to the pressure cylinder so as to boost the pressure inside the pressure cylinder.

Abstract: An extrusion die device for a molding machine includes an accumulator which includes a housing, a core extending into the housing, and a main passage formed between the core and the housing and having interconnected upper and lower passage sections. The upper passage section has inner and outer annular passages spaced apart radially from each other. A die head has a die orifice and a die exit connected to a bottom end of the lower passage section. An extruding unit includes an annular plunger disposed movably within the housing, and dividing the upper passage section into the inner and outer passage sections. Two differently colored plastics can be extruded by the single annular plunger from the inner and outer passage sections through the die head.

Abstract: An exemplary liquid crystal display (1) includes a liquid crystal panel (13), and a frame (18). The liquid crystal panel has a block (134) outwardly extending from a side surface (132) thereof. The frame includes a side wall (181) defining a gap (189) thereat, and a reinforcing part (188) at a bottom portion of the frame that bounds the gap. The liquid crystal panel is received in the frame, and the block is received in the gap.
