Detailed Description

The present invention will now be further described with reference to the accompanying drawings.

Example one

As shown in fig. 1 and 2, the reverse extruder die roll-off device includes: a rolling plate 1; the turning rod 2 is fixed on the extruder, and the rolling plate 1 is movably positioned above the turning rod 2; one end of the rolling plate 1 is rotatably arranged on the supporting plate 6; the cylinder 7, the cylinder 7 is installed on extruder, the brace 6 is fixed on piston rod of the cylinder 7; the limiting device is arranged on the rolling plate 1 and is positioned on one side of the turnover rod 2; the reverse extruder die roll-off device comprises a roll-off state and a material pushing state, wherein the air cylinder 7 extends out in the roll-off state, the rolling plate 1 is in an inclined state, one end, located on the supporting plate 6, of the rolling plate is lower than the other end, the die 9 rolls to the limiting device, the air cylinder 7 retracts in the material pushing state, the overturning rod 2 pushes the rolling plate 1 to rotate, and the rolling plate 1 pushes the die 9 away from the supporting plate 6.

Reduce the angle of roll board 1, reduce the rolling speed and the impact force of mould 9 to through stop device with mould 9 restriction in roll board 1 when mould 9 will leave roll board 1, then drive layer board 6 through cylinder 7 and descend, make mould 9 by the propelling movement to the left bracket on, very big reduction the impact of mould 9 with the bracket, bracket long service life, and the difficult stake mark that appears in mould 9 surface.
