In addition, the descriptions related to "first", "second", etc. in the present invention are only for description purposes, not specifically referring to the order or sequence, and are not intended to limit the present invention, but only to distinguish the components or operations described in the same technical terms, and are not to be construed as indicating or implying any relative importance or implicit indication of the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

The utility model discloses a mould for corner is handled, including last mould 1 and lower mould 2, the edge of 2 bottoms of lower mould is fixed with annular supporting seat 3, go up integrated into one piece and have four drift 11 that are array form and distribute on the lower terminal surface of mould 1, the internal edge department of every drift 11 all is provided with the concave surface 12 of arc form, be provided with in the lower mould 2 with the 21 that punch a hole that set up of 11 one-to-one of every drift, the shape and the size of the cross-section of every 21 that punch a hole is the same with the shape and the size of the cross-section of the drift 11 that corresponds, four sides of 2 up end of lower mould all are provided with the location structure that is.

Each positioning structure comprises a limiting block 4, a long hole 41 extending along the length direction of the limiting block 4 is arranged in the limiting block 4, a bolt assembly 42 penetrates through the long hole 41, and the limiting block 4 is fixed on the lower die 2 through the bolt assembly 42; by adopting the structure, after the position of the limiting blocks is adjusted, the limiting blocks can limit the plate to be stamped which is placed in the area enclosed by the four limiting blocks; when the position of stopper is adjusted to needs, only need to twist the bolt subassembly loose, then can adjust the position of stopper, the position adjustment of stopper back of finishing, it can to tighten bolt subassembly again.

An inclined surface 43 for guiding the plate to be punched is arranged at the inner end part of each limiting block 4 so as to facilitate the plate to be punched to be embedded into the area surrounded by the four limiting blocks 4; through the setting of inclined plane, when the panel that will treat the punching press is embedded into the region that four stoppers enclose, the edge of panel can with the inclined plane cooperation direction to in the region that four stoppers enclose is embedded into to panel convenience.

A cylinder 5 is fixed in the middle of the lower end face of the lower die 2, and a through hole 22 for a piston rod of the cylinder 5 to pass through is formed in the middle of the bottom of the lower die 2; after adopting this kind of structure, after the panel punching press was accomplished, through the extension of the piston rod of cylinder, can be ejecting in the region that the panel after the punching press was accomplished encloses from four stoppers to can bring the convenience for taking out of panel.

The outer end part of the piston rod of each cylinder 5 is sleeved with a rubber sleeve 51 in an interference fit manner; through the setting of gum cover, the piston rod of cylinder can increase the frictional force between the piston rod of cylinder and the panel when pushing away panel, so, the phenomenon of skidding appears between the piston rod of cylinder and the panel.
