The utility model discloses a mechanism of loosing core that slides outward of plastics tray mould servo motor drive, after plastics tray injection moulding, drive movable mould board and fixed die plate die sinking by the injection molding machine power, the outer slider stays on the movable mould board, in the die sinking in-process, after outer slider separates with the fixed die plate promptly, the mechanism work of loosing core that slides outward, servo motor passes through the driving gear and drives driven gear, driven gear drives the rotation screw rod and rotates, the rotation screw rod rotates the back, make the swivel nut along the screw thread translation on the rotation screw rod, drive the outer slider and slide outward through 7 words pieces, thereby it looses core to drive steel-pipe hole core bar. This scheme adopts servo motor drive, and the precision of loosing core is high, especially when outer slider and steel pipe core pulling rod reset, effectively avoids slider and core rod and other mould parts to bump, extension mould life and reduction maintenance number of times. Meanwhile, the servo motor and the rotating screw rod are arranged side by side, so that the assembly space can be saved, the whole length and width of the mold can be shortened, the mold is suitable for processing of a medium-sized injection molding machine, and the equipment investment cost can be reduced.
The utility model discloses a mechanism of loosing core slides outward in plastics tray mould servo motor drive, outer slider set up respectively in the front of movable mould board and fixed die plate, back, left and right four positions, two sets of mechanisms of loosing core that slide outward are connected to the outer slider in every position, drive outer slider simultaneously by two sets of mechanisms of loosing core that slide outward and loose core, it is more smooth to loose core. The outer drawing support is provided with a slide bar, and the outer sliding block slides on the slide bar when sliding outwards, so that the outer sliding block slides more stably.
