fig. 2 is the utility model discloses turn-ups terrace die and ejector plate complex sketch map.

Detailed Description

As shown in fig. 1, the utility model relates to a cell-phone board turn-ups mould in a poor light, including apron 1, upper die base 2, upper padding plate 3, punch holder 4, backstop board 5, take off flitch 6, lower bolster 7, lower bolster 8, die holder 9, take off material pole 10, take off material spring 11, take off material bolt 12, turn-ups die 13, die take off flitch 14, flanging die 15, liftout plate 16, liftout pole 17, liftout pole spring 18.

The cover plate 1, the upper die base 2, the upper padding plate 3 and the upper clamping plate 4 are fixed together in sequence, the lower die plate 7, the lower padding plate 8 and the lower die base 9 are fixed together in sequence, the stop plate 5 and the stripper plate 6 are fixed together, and the stop plate 5 and the stripper plate 6 are arranged between the upper clamping plate 4 and the lower die plate 7.

The stripper spring 11 is arranged in the upper die holder 2, two ends of the stripper spring 11 respectively abut against the upper ends of the cover plate 1 and the stripper rod 10, the lower part of the stripper rod 10 movably penetrates through the upper backing plate 3 and the upper clamping plate 4, the lower end of the stripper rod 10 penetrates through the upper clamping plate 4 and then extends into the stripper plate 6 and is fixedly connected with the stripper bolt 12, the stripper bolt 12 is fixed on the female die stripper plate 6, the female die stripper plate 14 is movably sleeved in the flanging female die 13, and the flanging female die 13 is fixedly arranged on the stripper plate 6; the flanging male die 15 is fixed on the lower die plate 7, the flanging male die 15 is opposite to the flanging female die 13, the ejector plate 16 is movably sleeved on the flanging male die 15, the upper end of the ejector rod 17 abuts against the ejector plate 16, the middle part of the ejector rod 17 movably penetrates through the lower die plate 7 and the lower backing plate 8, the lower end of the ejector rod 17 abuts against an ejector rod spring 18, and the ejector rod spring 18 is installed in the lower die seat 9.
