Abstract
The utility model provides a die core overturning device. The overturning device comprises an overturning mechanism which consists of an engine base and a die core, wherein an overturning shaft is fixedly arranged on the engine base; a bracket connecting rod is arranged below the die core and is rotatably connected with the overturning shaft; a rotating support on which a lead screw is arranged is fixed on the engine base through a one-way hinge; a two-way hinge is arranged by passing through the lead screw and is in running fit with the bracket connecting rod through a connecting rod shaft of the two-way hinge; the lead screw is in clearance fit with a nut; and the nut is in clearance fit with the two-way hinge. When the lead screw rotates, the nut moves along the lead screw, the two-way hinge is pulled to move by the nut, and the bracket connecting rod is driven to rotate around the overturning shaft; the distance from a fixed point to a movable point is changed by utilizing the movement of the lead screw and the nut, the bracket connecting rod is pulled to rotate around the shaft so as to drive the die core to rotate; and the lead screw and the nut have the self-locking function, so that the positioning is accurate. The die core overturning device is accurate in positioning, low in working strength, and easy to rotate.

A kind of core rod turning device of the utility model, its objective is provides a kind of core rod turning device, solves the problem that the location is inaccurate in the core rod switching process, labour intensity is large.
In order to address the above problem, the utility model is achieved through the following technical solutions:
The utility model is a kind of core rod turning device, this turning device comprises switching mechanism, switching mechanism comprises support and core rod, be installed with trip shaft at support, below core rod, be provided with the carriage connecting rod, trip shaft and carriage connecting rod are rotationally connected, on support, be fixed with rotational support by unidirectional hinge, in rotational support screw mandrel is installed, pass screw mandrel and be provided with two-way hinge, two-way hinge is rotatably assorted by pitman shaft and the carriage connecting rod of a two-way hinge, the movable screw that cooperates of screw mandrel, and screw cooperates with two-way hinge is movable.
Further improvement of the utility model is: screw comprises screw body, axis pin base hole and screw screw, and the axis pin base hole is perpendicular to the dual-side of screw, and the screw screw is in end face and the bottom surface of screw, and vertical with the axis pin base hole.
Further improvement of the utility model is: two-way hinge also comprises crotch and pin shaft hole, crotch is the U-shaped structure, the center line of pin shaft hole and pitman shaft quadrature, and pin shaft hole and axis pin base hole are movingly, on two-way hinge, also be provided with bearing pin, bearing pin and pin shaft hole stationary fit.
Further improvement of the utility model is: the screw body is box structure.
The beneficial effects of the utility model are: when rotating threaded shaft, screw moves along leading screw, and screw affects two-way hinge to move and the carriage connecting rod is rotated around trip shaft, so core rod upset and the angle of its upset is determined along the distance that leading screw moves by screw.Utilize the movement of leading screw and screw and change the distance of fixing a point and moving point, affect the carriage connecting rod to pivot, the upset of band moving-mould-core; Because leading screw and screw have auto-lock function, so accurate positioning.
The utility model is simple in structure, and is easy to make, accurate positioning, and labour intensity is low, and upset is easily.
