Abstract: A lever-type mold ejection mechanism is arranged on a platen of a mold in the injection molding machine. The lever-type ejection mechanism includes a base body arranged on the platen; an actuating cylinder having a motion shaft; a link rod having a first end and a second end opposite to each other, wherein the first end is pivotally disposed on the base body through a first pivot axis, and the second end is pivotally disposed on an end of the motion shaft of the actuating cylinder through a second pivot axis, and the link rod has a movable ejector pin at its bottom surface adjacent to the first end; and a ejector rod resisting between the ejector pin and the mold. The actuating cylinder is operated to push the mold through the link rod in a lever manner so as to obtain enough pushing force.

Abstract: A LED lead frame structure and a method of manufacturing LED lead frames are disclosed, in which the LED lead frame structure includes a metal base and insulating casings. The metal base has a plurality of lead areas, and two holes are formed on two opposing sides of each lead area. The insulating casings are formed on the lead areas respectively.

Abstract: A mold for an LED lampshade comprising: an upper mold defined with a cavity in the bottom surface thereof; a lower mold defined with a slide recess corresponding to the cavity of the upper mold, a movable ejection block being received in the slide recess, the movable ejection block being movable back and forth along the slide recess, a cavity being defined in the top surface of the movable ejection block; and multiple ejection rods respectively disposed at the lower mold and at opposite sides of the movable ejection block and extending from the bottom of the lower mold to the top of the lower mold. When the mold of the present invention is used to injection mold, the LED lampshade is ejected by the movable ejection block in a manner of surface contact thereby preventing ejection marks on the surface of the LED lampshade.
