The utility model discloses a kind of imitative rattan plastic chair unilateral side curved handrail footing core-pulling mechanisms, when imitative rattan plastic chair
After handrail and footing integrated injection molding, mold is opened from solid plate and moving template, oblique in solid plate while die sinking
Guide rod and the oblique guide hole of side action sliders cooperate, and drive the side action sliders on front side, left side, right side to extract out outward, then core pulling
The piston rod of oil cylinder drives pulling plate to be displaced outwardly, and pulling plate is displaced outwardly through lateral guide groove band action-oriented pillar, and guiding pillar is simultaneously
Cooperate with arc guide barrel and lateral guide groove, makes to be oriented to pillar while moving backward along arc guide barrel and lateral guide groove shifting
Dynamic, guiding pillar is moved with movable slider along the radian of arc guide barrel, sliding block drive handrail Loose core block or footing Loose core block along
The radian of arc guide barrel is mobile, so that handrail Loose core block and footing Loose core block be made to extract handrail and the bottom of the imitative rattan plastic chair out
Foot finally drives thimble that the integral type handrail and footing of completing core pulling are ejected abjection upwards by upper and lower ejector retainner plate.This programme is imitative
Rattan plastic chair unilateral side curved handrail footing core-pulling mechanism, by the way that the piston rod of core pulling oil cylinder is connected pulling plate, the transverse direction on pulling plate
The arc guide barrel of guide groove and arc-shaped guide rail is simultaneously oriented to guiding pillar, enables sliding block while being displaced outwardly along arc
Guide groove is mobile, and sliding block drives the handrail and footing of handrail Loose core block and footing Loose core block extraction imitative rattan plastic chair, and structure is simple, accounts for
It is few with the space of mold, make the volume-diminished of mold, without the injection molding machine of more large-tonnage, reduce manufacturing cost, demoulds
Smoothly.
The utility model imitative rattan plastic chair unilateral side curved handrail footing core-pulling mechanism is provided in the oil cylinder fixed plate solid
Determine hole, a moving template of arc-shaped guide rail is mutually fixed, and other end is inserted into fixation hole.Oil cylinder fixed plate is to the another of arc-shaped guide rail
Head plays support, fixed function, and mating, easy for installation.
