As shown in Figure 1 to Figure 3, a kind of arc-shaped core pulling structure of mold of the present embodiment includes big sliding block 1, rotation oil cylinder 2
With rotation mold insert 3, the rotation oil cylinder 2 is arranged on big sliding block 1, and rotation oil cylinder is connect with big sliding block by shaft 4.Big sliding block
1 has arc accommodating chamber 11, and rotation mold insert 3 is arranged in arc accommodating chamber 11 and is pivotally connected with big sliding block 1.Rotation oil cylinder 2
With telescopic shaft 21, telescopic shaft 21 and rotation mold insert 3 are pivotally connected.In above-mentioned technical proposal, pass through the promotion of telescopic shaft 21, energy
Rotate rotation mold insert in arc accommodating chamber 11, to enable to rotate mold insert and the disengaging of syphon shape product 10.By certainly
The transmission step of power excessive in previous arc-shaped core pulling structure can be greatly simplified by turning oil cylinder driving rotary part, to reduce
A possibility that breaking down when mold volume production；And the rotation characteristic of the rotation oil cylinder is utilized, while pushing rotation mold insert,
The swing angle of rotation mold insert can be adapted to automatically, thus is less prone to the Caton in motion process and is hit mould phenomenon.Work as rotation
Mold insert moves to extreme position (rotation angle in the reasonable scope), need when return rotation oil cylinder can react rapidly guarantee its
The continuity of movement.In the present embodiment, arc mold insert is connect with big sliding block by the first pivot 20, and telescopic shaft and rotation mold insert are logical
Cross the connection of the second pivot 30.
The rotation angle and movement of the arc-shaped core pulling structure of the mold of the present embodiment needed in design to rotation mold insert
Track is simulated, and reaches the optimal mould unloading of product by reasonably rotating angle and arc-shaped core pulling distance.Method is such as
Under:
The first step, it is thus necessary to determine that the rotation center of product finds out motion profile, calculates arc-shaped core pulling distance (rotation angle
Degree)；
Second step, finds out the connecting shaft (driving center) of rotation oil cylinder and motion profile L, initial best sticking point, i.e., and the
The position of two pivots 30；
Third step selects the rotation oil cylinder of corresponding stroke according to arc-shaped core pulling distance, determines that rotation oil cylinder rotation center is fixed
Position axis point, the i.e. position of shaft 4.
In the present embodiment, the rotation mold insert 3 includes mold insert main body 31 and rotor plate 32, and the setting of rotor plate 32 is being inlayed
31 side of part main body, rotor plate 32 are connect with telescopic shaft end pivot.To be able to drive mold insert body rotation by rotor plate.
In the present embodiment, the mold insert main body 31 is arc, and mold insert main body is arranged in arc accommodating chamber 11, to realize
Arc-shaped core pulling.
In the present embodiment, arc-shaped core pulling structure includes small-sized core 5, and small-sized core 5 is arranged in big slider top, consequently facilitating mould
Tool processing.
