Abstract:
1. An injection molding device, comprising: a male part; a female part detachably engaged with the male part, wherein sides of the male part and the female part facing a same direction collectively form an insertion groove thereon; a vertically-moveable slider detachably inserted in the insertion groove, and formed with a first inclined plane; a horizontally-moveable slider detachably inserted in the insertion groove, formed with a second inclined plane being slidably engaged with the first inclined plane, wherein a closed cavity is collectively defined by the vertically-moveable slider, the horizontally-moveable slider, the female part and the male part, an elastic element, wherein two opposite ends of the elastic element are respectively abutted against the vertically-moveable slider and the horizontally-moveable slider, wherein, after a plastic shell case is formed in the closed cavity and the female part is moved in a first direction to be away from the male part, the elastic element pushes the horizontally-moveable slider in a second direction which is perpendicular to the first direction for allowing the horizontally-moveable slider to be away from the male part, with the horizontally-moveable slider being gradually moved away from the male part, the vertically-moveable slider is gradually moved in a third direction which is opposite to the first direction for being away from an arc-shaped inner edge of the plastic shell case.
