The molding guiding mechanism to match each other is equipped at the both ends of upper mold matrix and lower die matrix.

Preferably, the edge mould periphery is equipped with several workpiece and imports locating rod, which imports locating rod top For the slide-in face of arc, lower part is vertical positioning plane, and each workpiece, which imports, positions this slide-in face and the equal face of positioning plane To the inside of edge mould.

Preferably, the molding guiding mechanism includes the rectangular guide pad and lower die matrix of upper mold matrix both ends protrusion The rectangular sliding slot of two concave ends is the sliding surface worked in coordination between the side and the side of direction sliding slot of rectangular guide pad, It is equipped with vertical sliding sleeving hole on guide pad, vertical slide bar is equipped in sliding slot, slide bar, which penetrates in sliding sleeving hole, to be become vertically Sliding pair.

The technique effect of the utility model

This repaiies the crease-resistant drawing composite die in angle, by the edge mould in the flanging plane and lower die of upper mold first to workpiece edge It is clamped fixation, then moment carries out deburring before mold drawing, and the control of edge mould can ensure to feed in drawing process Uniformly, material stacking is prevented, product corrugation, the generation of drawing crack phenomenon is significantly reduced, improves Product Precision, improve finished product Rate reduces production cost, reduces process, saves energy consumption.

Specific implementation mode

Embodiment one：Referring to Fig. 1-10, one kind repairing the crease-resistant drawing composite die in angle, including part of the upper die and lower mold portion in figure Point, it is characterized in that：

The edge mould periphery is equipped with several workpiece and imports locating rod, and it is arc which, which imports locating rod top, Slide-in face, lower part are vertical positioning plane, and each workpiece, which imports to position this slide-in face and position plane, both faces towards edge mould Inside.

The molding guiding mechanism includes that the rectangular guide pad and lower die matrix both ends of upper mold matrix both ends protrusion is recessed Sunken rectangular sliding slot is the sliding surface worked in coordination between the side and the side of direction sliding slot of rectangular guide pad, is being oriented to Block is equipped with vertical sliding sleeving hole, vertical slide bar is equipped in sliding slot, slide bar, which penetrates, becomes vertical sliding pair in sliding sleeving hole.

The blank of tablet when in use, is first placed on the edge mould of part of the lower die by the mold, the work on edge mould periphery Part imports the slide-in and positioning that locating rod is used for workpiece edge, then part of the upper die downlink, upper mold under the auxiliary of guiding mechanism Blank periphery is clamped with the edge mould cooperation in lower die and is flattened by partial flanging plane, then proceedes to downlink, flanging mold compression Into the die cavity of lower die matrix, the corner of blank is trimmed in downlink, at this time upper corner tool and the cooperation of lower corner tool after support spring Fall, prevent the accumulation for generating material when drawing herein, generates fold, while lower draw forming die protrusion is matched with upper draw forming die The problem of conjunction carries out drawing and moulding to blank, and such material enters even, is not likely to produce fold and crackle, can be significantly Yield rate is promoted, process is reduced, reduces energy consumption.
