Summary of the invention
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, prevent core fracture, the provision for disengagement that improves the extrusion die upper and lower mould of die life when a kind of dismounting is provided.
The technical scheme that the utility model solves its technical problem employing is: the provision for disengagement of this extrusion die upper and lower mould, it is characterized in that: comprise and move up and down power set and friction winding device, move up and down power set bottom and be fixedly connected with friction winding device, and can drive friction winding device to move up and down, friction winding device inner side is provided with the frictional connection mechanism being connected with the outer side contacts of patrix of extrusion die.
At the arranged outside friction winding device of patrix, and connect as the power set that move up and down that promote power at the top of friction winding device, drive friction winding device to move up and down by moving up and down power set, can under the effect of frictional force, drive by friction winding device the separation of upper and lower mould, simple in structure, easy and simple to handle, thoroughly avoid available technology adopting hammer to knock the impact on mould, prevent strong seismaesthesia or cause die deformation and core rod fracture, improve operating efficiency, extended the life-span of mould simultaneously.
The described power set that move up and down are hydraulic cylinder, pneumatic cylinder or electric expansion bar. Movable end by hydraulic cylinder, pneumatic cylinder or electric expansion bar is as the mobile power of friction winding device, simple, convenient, is easy to install and save space.
Described friction winding device comprises fixed head and frictional connection cover, and fixed head and frictional connection cover are fixedly connected on the described lower end that moves up and down power set by set bolt, and frictional connection mechanism is arranged on the inner side of frictional connection cover.
In the inner side of frictional connection cover, frictional connection mechanism is set, realizes separating of upper and lower mould by the contact friction force forming between frictional connection mechanism and patrix.
Described frictional connection mechanism comprises fan-shaped thorn wheel and bolt, and fan-shaped thorn wheel is fixed by bolt, and on fan-shaped thorn wheel, the fan-shaped flank of tooth of arranging is arranged on and the patrix one side of side contacts outward. Increase the frictional force between frictional connection mechanism and patrix by the profile of tooth of fan-shaped setting, guarantee the separating effect between patrix and counterdie.
Described fan-shaped thorn wheel is at least provided with two groups. Also can arrange many groups, can adopt uniform mode to arrange, concrete quantity can decide according to the size of upper and lower mould.
In frictional connection cover, bottom is provided with the projection of fixing described fan-shaped thorn wheel.
Compared with prior art, the beneficial effect that the utility model has is:
1, at the arranged outside friction winding device of patrix, and connect as the power set that move up and down that promote power at the top of friction winding device, drive friction winding device to move up and down by moving up and down power set, can under the effect of frictional force, drive by friction winding device the separation of upper and lower mould, simple in structure, easy and simple to handle, thoroughly avoid available technology adopting hammer to knock the impact on mould, prevent strong seismaesthesia or cause die deformation and core rod fracture, improve operating efficiency, extended the life-span of mould simultaneously.
2, at the fan-shaped thorn wheel of arranged outside of patrix, and on fan-shaped thorn wheel, the fan-shaped flank of tooth of arranging is arranged on and the patrix one side of side contacts outward, increase the frictional force between frictional connection mechanism and patrix by the profile of tooth of fan-shaped setting, guarantee the separating effect between patrix and counterdie.
