PURPOSE:To contrive simplification of the whole of a device by preventing a deformation and distortion of both unloading arms of a molded article and sprue in spite of a matter that both the arms have been lightened, by making and ascending an descending movement mechanism of the arms into constitution wherein ascending and descending movements of a holding arm are made to perform. CONSTITUTION:A holding arm 38 is arranged in the direction meeting at right angles with a rail 35, in the vicinity of the rear end of which the arm 38 is held slidably on two guide posts 39 running in parallel with each other which are provided on a movable block 36 in a standing state. It becomes that the holding arm 38 is guided by the guide post 39 and moves vertically by a method wherein a servomotor 42 is truned positively and negatively. A main arm 44 is held by the holding arm 38 on the top of the same and extended in a vertical direction. The main arm 44 is held slidably by the holding arm 38 on the top of the same while the same is kept holding the vertical direction. |
