One end end of spring is equipped with the second limited block.
Dual thimble structure described in the utility model, wherein the upper die holder is equipped with the first screw, the upper acting as a cushion
Lower section is fixedly connected with upper padding plate, is fixedly connected with cope plate below the upper padding plate;First limited block and described second
Mounting hole matching.
Dual thimble structure described in the utility model, wherein the upper padding plate and the cope plate be equipped with it is described
The third mounting hole of first thimble cooperation.
Dual thimble structure described in the utility model, wherein first mounting hole far from second screw one
End is equipped with the second centre hole cooperated with second thimble, and the one end of first mounting hole closely from second screw is equipped with
With the matched second spring hole of the second spring, second limited block is matched with the second spring hole.
The utility model has the beneficial effects that: the first spring and second spring bounce simultaneously in die sinking, the first spring
First thimble is bounced, the second spring in the first thimble bounces the second thimble;The first spring and second spring are same when molding
When compressed, the second thimble is shunk in the first thimble, and the first thimble is shunk in mould;It realizes in centainly closure limit,
Increase de- material stroke, improve working efficiency, reduces production cost.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, below in conjunction with attached drawing and reality
Applying example, the utility model is described in further detail, and the accompanying drawings in the following description is only section Example of the invention, for this
