Specific implementation mode
In the following, the substantive distinguishing features and advantage of the present invention are further described in conjunction with example, but the present invention not office
It is limited to listed embodiment.
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 there is arc accommodating chamber 11, rotation mold insert 3 to be arranged in arc accommodating chamber 11 and are pivotally connected with big sliding block 1.Rotation oil cylinder 2
With telescopic shaft 21, telescopic shaft 21 is pivotally connected with rotation mold insert 3.In above-mentioned technical proposal, pass through the promotion of telescopic shaft 21, energy
Rotation mold insert is enough set to be rotated in arc accommodating chamber 11, to enable rotation mold insert to be detached from syphon shape product 10.By certainly
The transmission step of excessive power in previous arc-shaped core pulling structure can be greatly simplified by turning hydraulic oil cylinder driving rotary part, to reduce
The possibility to break 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 interim card in motion process and is hit mould phenomenon.Work as rotation
Mold insert moves to extreme position（Rotation angle is 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 arc-shaped core pulling structure of the mold of the present embodiment needs the rotation angle to rotating mold insert and movement in design
Track is simulated, and reaches the optimal mould unloading of product by rational rotation 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 movement locus, calculates arc-shaped core pulling distance（Rotation angle）；
Second step finds out the connecting shaft of rotation oil cylinder and movement locus L（Driving center）, initial best sticking point, i.e. the second pivot
The position of axis 30；
Third walks, and the rotation oil cylinder of corresponding stroke is selected according to arc-shaped core pulling distance, determines rotation oil cylinder rotation center locating shaft
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 the rotor plate 32 is being inlayed
31 side of part main body, rotor plate 32 are connect with telescopic shaft end pivot.To which mold insert body rotation can be driven 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.
In the present embodiment, arc-shaped core pulling structure includes oil inlet pipe 6 and flowline 7, and oil inlet pipe 6 connects with rotation oil cylinder bottom
It connects, flowline is connect with rotation oil cylinder side, and hydraulic oil conveying can be controlled by oil inlet pipe and flowline.
In the present embodiment, the big sliding block 1 includes holder 12, linking arm 13 and slider body 14, slider body 14 and branch
The setting of the interval of frame 12, slider body are connect with holder by linking arm 13, and rotation mold insert is arranged on slider body, rotation oil cylinder
It is arranged on holder.
In the present embodiment, the big sliding block 1 includes mounting portion 15 and arc-shaped guide rail 16, and mounting portion 15 is arranged in arc-shaped guide rail
16 tops, mounting portion 15 constitute arc accommodating chamber, one end closing of arc accommodating chamber with arc-shaped guide rail.Pass through above-mentioned technical side
Case so that rotation mold insert can arcuately guide rail slide, meanwhile, when sliding into the blind end of arc accommodating chamber, it can stop, it is real
Now to the limit of rotation mold insert.
In the present embodiment, the shaft is perpendicular to telescopic shaft, to which when telescopic shaft moves, rotation oil cylinder can be around the shaft
Rotation.
Through the above technical solutions, mold, in stripping operation, after front and back mould is opened, piston driving telescopic shaft pushes rotation
Mold insert pushes in rotation and completes arc-shaped core pulling action；After the completion of arc-shaped core pulling action, after big sliding block is under rotation hydraulic oil cylinder driving
It moves back（Such as Fig. 3 arrow directions）The small-sized core core pulling of itself is completed, while rotation mold insert being driven to continue to retreat, until rotation mold insert is complete
Total detachment product, entire core pulling process terminate.
A kind of arc-shaped core pulling structure of mold of the present embodiment can greatly reduce the transmission step of power between component, rotation
Oil cylinder directly acts on rotary core pulling mold insert, reduces the loss of power and the rotation oil cylinder can have universal property with rotation, will not go out
