The technical scheme that realizes the utility model purpose is: but a kind of Working piece positioning device of fast demoulding has base, positioner and hold down gag; Described positioner is fixed on the centre of base by securing member; Described hold down gag has two groups, and the corresponding both sides that are arranged on positioner; Described positioner has the cushion block of bearing, location main body and retractable; Described bearing is fixed on base by securing member; The rear end of described location main body is rotatably connected on bearing by bearing pin; Described cushion block has two, and is symmetricly set on the front end of location main body by screw; Described positioner also has rotation can make two cushion block spacings be in the rotating shaft of maximum position; The through hole on the main body of location is radially passed in described rotating shaft.

Also has handle on the described positioner of technique scheme; Described handle lower end is welded on the rotating shaft upper end.

The described rotating shaft of technique scheme is stepped, ascending nut canned paragraph, rotating shaft interlude and the handle canned paragraph of being followed successively by of rotating shaft; On described rotating shaft interlude, symmetry has two grooves.

The bottom of the described location of technique scheme main body is fixed with a positioning block; Have the groove corresponding with locating piece on described bearing.

The described handle of technique scheme is " T " font.

The described hold down gag of technique scheme has clamping cylinder.

After adopting technique scheme, the utlity model has following positive effect:

(1) positioner of the present utility model also has rotation and can make two cushion block spacings be in the rotating shaft of maximum position; The through hole on the main body of location is radially passed in rotating shaft; Make the workpiece fast demoulding, improved production efficiency, reduced production cost, also got rid of the potential safety hazard of using row to hang.

(2) also has handle on positioner of the present utility model; The handle lower end is welded on the rotating shaft upper end; Can be so that the rotation of rotating shaft by handle, lift-pull handle can make workpiece separate with positioner fast simultaneously.

(3) bottom of location of the present utility model main body is fixed with a positioning block; Have the groove corresponding with locating piece on bearing; Can guarantee that locating main body is in the center.
