Abstract
The invention discloses a mould capable of forming negative angles at a time. The mould comprises an upper mould, a lower mould, a lower mould forming block, an upper mould forming block and a negative angle forming mechanism, wherein the lower mould forming block is installed on the lower mould, comprises a fixed block and movable blocks located on two sides of the fixed block, and is of an inverted trapezoid shape overall; the fixed block is trapezoidal, the movable blocks are of an inverted trapezoid shape, and the fixed block and the movable blocks are connected and matched through guide rails on adjacent surfaces; the bottom surfaces of the two movable blocks are each matched with an ejection rod installed on the lower mould through a spring; the negative angle forming mechanism is installed on the upper mould, is located on one side of the upper mould forming block and comprises a base, a rotary negative angle forming block, a spring and an ejection rod. The mould capable of forming negative angles at a time is simple in structure, reasonable in design, capable of forming and machining negative angles of parts at a time through the rotary negative angle forming block, high in machining efficiency, capable of realizing different forming angles by replacing rotary negative angle forming blocks with different negative angle forming openings, and good in universality.
Description
Technical field
The present invention relates to a kind of mould, specifically a kind of mould for negative angle bending and molding.
Background technology
For the needs of satisfied use or design, numerous parts needs bending to go out negative angle, and negative angle bending and molding is very common in machined.At present, limitting by mould structure, for realizing negative angle bending and molding, general what adopt is three step processing methods, and its concrete procedure of processing is, 1, first by Total Product upwards bending, as shown in Figure 1; 2, negative angle bending and molding is again incited somebody to action, as shown in Figure 2; 3, after completing above-mentioned processing, then the bending leveling of product step 1, product is resetted, as shown in Figure 3.This kind of mode, needs three step processing, and adds man-hour, need three kinds of different moulds to coordinate, and part also needs to be shifted after a step processing, and send into next step processing, make negative angle forming process very time-consuming, effort, and working (machining) efficiency is low, processing cost is high.
Summary of the invention
The object of the invention is to the deficiency overcoming the existence of existing negative angle forming machining, a kind of mould that can realize disposable negative angle forming is provided.
For achieving the above object, the technical solution adopted in the present invention is:
A mould for disposable negative angle forming, includes upper die and lower die, counterdie forming blocks, upper die forming block, negative angle forming mechanism.
Counterdie forming blocks is arranged on counterdie, comprises fixed block and is positioned at the movable block of fixed block both sides;
Described counterdie forming blocks entirety is in falling shape, and described fixed block is trapezoid, and movable block is inverted trapezoidal, and fixed block and movable block are connected by the guide rail on adjacent surface and coordinate;
Described two movable block bottom surfaces are respectively coordinated by the push rod of spring fitting on counterdie with one;
Described upper die forming block is arranged on patrix;
Described negative angle forming mechanism is arranged on patrix, is positioned at upper die forming block side;
Described negative angle forming mechanism includes pedestal, rotatable negative angle forming block, spring, push rod;
Described pedestal there is arc installing port;
Described rotatable negative angle forming block is spherical in shape, is installed in the arc installing port of pedestal;
Described rotatable negative angle forming block has the negative angle forming mouth for negative angle forming;
Described rotatable negative angle forming block is also provided with gathering sill, and this gathering sill coordinates with by the push rod of spring fitting in pedestal;
Described rotatable negative angle forming block coordinates with described movable block contraposition.
When the present invention works, patrix is descending, drive upper die forming block and negative angle forming mechanism DL synchronization, during bending and molding, rotatable negative angle forming block top pressure part, rotate by under the effect of downstream pressure, the negative angle forming mouth that it is arranged is coordinated with movable block and forms negative angle forming chamber, negative angle forming processing is carried out to part, after machining, patrix is up, the top pressure that rotatable negative angle forming block enters spring by push rod resets, be separated with part, movable block is pressed by the top of push rod simultaneously, up, drive part entirety up, and depart from part negative angle forming face, part is facilitated to take out.
Structure of the present invention is simple, reasonable in design, utilize turnable negative angle forming block to realize processing the disposable negative angle forming of part, working (machining) efficiency is high, can angle forming angle be achieved by the turnable negative angle forming block changing different negative angle forming mouth, versatility is good.
