Description

Slanting-wedge double-acting core-loosing type punch-forming mold

Technical field

The utility model relates to a kind of punch-forming mold, especially a kind of slanting-wedge double-acting core-loosing type punch-forming mold.

Background technology

Because the product die cavity has stricter dimensional requirement, and cold-stamped part sheet material in forming process produces the cavity dimension that distortion will certainly have influence on product.So must use punch to guarantee cavity dimension.And often the punch taking-up is inconvenient after the moulding end.Need punch be pounded out from workpiece with instrument, tend to injure workpiece like this.Has only the mould that uses the structure of loosing core like this, the mould slide block backhaul process of the structure of loosing core is used the spring effect, and spring use can produce after a period of time tired and ineffective, slide block can not effectively playback, and causes tiltedly carving in the ensuing punching course the last plane that directly acts on slide block mould is damaged.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, the slanting-wedge double-acting core-loosing type punch-forming mold that provide a kind of and need not to use spring, avoid tiltedly carving in the punching course that the last plane that directly acts on slide block makes that mould damages, punch is convenient in demoulding after the punching press.

The technical scheme that provides according to the utility model, on frame, fixedly install lower module, be provided with mount pad at the lower module upper surface, both sides at mount pad are equipped with take-up housing, on each take-up housing, be equipped with the slide block that is slidingly connected with it, the opposing end surface of slide block is provided with the punch that cooperatively interacts, on slide block, be fixed with cover plate, exist the gap to form slideway between cover plate and the take-up housing, described slide block promptly is slidingly connected in the slideway between cover plate and the take-up housing, above frame, be connected with cope match-plate pattern, the lower surface of cope match-plate pattern is provided with the die that cooperates with punch, cope match-plate pattern lower surface above slide block is provided with tiltedly to be carved, described tiltedly carving by the column of vertical setting and the base plate that intersects with its obtuse angle that connects in the column bottom constitutes, the bottom of base plate is away from mount pad, described slide block offers working hole between the upper and lower end face, the upper end madial wall of described working hole is for using the inclined-plane with identical the closing up of madial wall gradient of base plate, and the lower end lateral wall of described working hole is for using the inclined-plane with identical the sliping off of lateral wall gradient of base plate.

On the frame in the slide block outside, be provided with baffle plate.The lower end madial wall of described working hole and upper end lateral wall are the wall body of vertical shape.Be provided with the groove of opening abduction in the mount pad upper surface, on the mount pad in the middle part of the bottom land of described groove, offer the jack of vertical setting, and the cross section of punch is the isosceles trapezoid shape of corner arc transition, correspondingly, described die lower surface is provided with the opening abduction and stamped groove that cooperate with punch.The opposing end surface of described slide block is provided with punch retainer, and punch retainer is provided with to install and pricks, and described punch promptly passes installing hole and is fixed on the slide block.

The utility model need not to use spring, change efficient reduction, the cost increase problem that spring brings after eliminating use a period of time, avoid tiltedly carving in the punching course the last plane that directly acts on slide block mould is damaged, and the knockout course of punch is very convenient after the punching press.

The specific embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

As shown in the figure: on frame 12, fixedly install lower module 11, be provided with mount pad 10 at lower module 11 upper surfaces, be equipped with take-up housing 9 in the both sides of mount pad 10, on each take-up housing 9, be equipped with the slide block 7 that is slidingly connected with it, the opposing end surface of slide block 7 is provided with the punch 6 that cooperatively interacts, on slide block 7, be fixed with cover plate 4, exist the gap to form slideway between cover plate 4 and the take-up housing 9, described slide block 7 promptly is slidingly connected in the slideway between cover plate 4 and the take-up housing 9, above frame 12, be connected with cope match-plate pattern 1, the lower surface of cope match-plate pattern 1 is provided with the die 2 that cooperates with punch 6, cope match-plate pattern 1 lower surface above slide block 7 is provided with tiltedly carves 3, describedly tiltedly carve 3 and constitute by the column 31 of vertical setting and the base plate 32 that intersects with its obtuse angle that connects in column 31 bottoms, the bottom of base plate 32 is away from mount pad 10, make lay respectively at the left and right sides tiltedly carve 3 be respectively approximate "

" with "

" shape; and offering working hole 71 between described slide block 7 upper and lower end faces; the upper end madial wall of described working hole 71 is sliping off with inclined-plane 73 of coincideing with lateral wall 34 gradients of base plate 32 for closing up with inclined-plane 72 of coincideing with madial wall 33 gradients of base plate 32, the lower end lateral wall of described working hole 71.

On the frame 12 in slide block 7 outsides, be provided with baffle plate 8.The lower end madial wall of described working hole 71 and upper end lateral wall are the wall body of vertical shape.Be provided with the groove 101 of opening abduction in mount pad 10 upper surfaces, on the mount pad 10 in the middle part of the bottom land of described groove 101, offer the jack 102 of vertical setting, and the cross section of punch 6 is the isosceles trapezoid shape of corner arc transition, correspondingly, described die 2 lower surfaces are provided with the opening abduction and stamped groove 21 that cooperate with punch 6.The opposing end surface of described slide block 7 is provided with punch retainer 5, and punch retainer 5 is provided with installing hole 51, and described punch 6 promptly passes installing hole 51 and is fixed on the slide block 7.

During work, workpiece is put into mount pad 10, carry out punching press then, when cope match-plate pattern 1 is descending, the madial wall 33 of base plate 32 promotes closing up with inclined-plane 72 of slide block 7, slide block 7 is moved ahead, punch 6 is pushed in the workpiece, simultaneously the stamped groove 21 of die 2 is drawn the opening of workpiece in, and when the lower end madial wall of tiltedly carving 3 column 31 madial walls and slide block 7 is straight line, tiltedly carving 3 will no longer play a driving role to slide block 7, punch enters in the workpiece 6 this moments fully, thereby guarantee that punch 6 can not bump extremely when descending when cope match-plate pattern continues, stamped groove 21 continuation that are die 2 are to the workpiece effect, and die 2 upwards left workpiece when cope match-plate pattern was up, when tiltedly carving the F inclined-plane of 3 E inclined-plane contact slipper 7, tiltedly carve the sliping off of lateral wall 34 hook movable sliders 7 of 3 base plate 32, slide block 7 is moved backward, punch 6 is withdrawed from workpiece with inclined-plane 73.

When die 2 separates with punch 6, tiltedly carving 3 moves upward, the lateral wall 34 of tiltedly carving 3 base plate 32 acts on sliping off with inclined-plane 73 of slide block 7, and slide block 7 move backward, punch 6 disengaging workpiece, because this punch 6 is to work simultaneously in both sides, so punch 6 is to break away from from workpiece simultaneously, the force rate that the workpiece both sides are subjected to is more even, can be because of the stressed inconsistent and folk prescription in both sides to pullling workpiece, cause product to be out of shape, problem such as pull because of stressed generation.
