Abstract

The utility model utility model discloses a stamping die, comprising an upper die, a lower die and a return mechanism; the upper die is provided with a molding punch and a pressing punch; the lower die is arranged in correspondence with the upper die and comprises a lower die holder and a molding slide block; the return mechanism is installed between the lower die holder and the molding slide block and can drive the molding slide block to return; wherein, in a die closing process of the stamping die, the pressing punch first pushes the molding slide block for a certain distance before the molding punch stamps material reels. According to the utility model, the molding slide block enters and withdraws from a stamping zone such that the stamping die can smoothly complete product punch molding but not obstruct the material reels from passing in and out of dies, thereby ensuring the continuity and accuracy of the production, and furthermore raising the production efficiency.

Description

Diel

Technical field

The utility model relates to a kind of mould, relates in particular to a kind of diel.

Background technology

See also Fig. 7, it does not break away from schematic diagram on the forming part 2 for a kind of shaped article 1 of existing diel; This forming part 2 is fixed in the diel, and shaped article 1 has barb and forming part 2 is wrapped in it, has hindered the path of strip turnover diel, manually shaped article 1 is taken out and can only rely on, and is unfavorable for saving time; And in artificial process of taking out shaped article 1, might change the shape of shaped article 1, cause shaped article 1 not reach the dimensional accuracy that needs and scrap, be unfavorable for saving cost.

The utility model content

The purpose of this utility model is to provide the diel that a kind of precision is high and can enhance productivity.

To achieve these goals, the utility model diel comprises a patrix, a counterdie and a return mechanism; This patrix has a cope match-plate pattern, is equiped with a moulding punching pin and a pushing punching pin on it, and the moulding punching pin has pressing part, and the pushing punching pin has the pushing part; The corresponding setting of counterdie with patrix, this counterdie comprises a die shoe and a forming slide, and this forming slide slidably is fastened on the die shoe, has forming part and scarf, this forming part is corresponding with the pressing part of moulding punching pin, and scarf is corresponding with the pushing part of pushing punching pin; This return mechanism is installed between die shoe and the forming slide, can drive the slide block return; Wherein, in the diel matched moulds process, pressing part is with before forming part is docked, and the pushing part promotes certain distance with slide block earlier.

Stamping Area is stretched into and withdraws from the utility model diel by forming slide, the punch forming that can finish product does not smoothly hinder strip turnover mould again, guarantees the continuity and the accuracy of producing, and then enhances productivity.

As further improvement, described return mechanism comprises a fixed head, fixedly a spiral pin and a spring, and this fixed head is fixed on the die shoe, which is provided with a through hole; Fixedly spiral pin passes this through hole and is fixed on the forming slide; Spring is compressed in fixed head and reaches fixedly between the spiral pin.

Described moulding punching pin lower end is arranged with one and takes off the material part.

The specific embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.

See also Fig. 1 and Fig. 2, the utility model diel comprises a patrix, a counterdie and a return mechanism 50.

Described patrix has a cope match-plate pattern (figure does not show), is equiped with a moulding punching pin 10 and a pushing punching pin 20 on this cope match-plate pattern, and this moulding punching pin 10 has a flat column first matrix 11, and these first matrix, 11 lower ends have a pressing part 111; This pushing punching pin 20 has a flat column second matrix 21, and these second matrix, 21 lower ends have a pushing part 211; These moulding punching pin 10 lower ends are arranged with taking off of a bulk and expect part 30, are used for the punching press guiding and reach fixedly strip 80.

The corresponding setting of described counterdie with patrix, comprise a die shoe (figure does not show) and a forming slide 40, what this forming slide 40 slided is fastened on the die shoe, have a forming part 41 and a scarf 42, this forming part 41 is corresponding with the pressing part 111 of described moulding punching pin 10, and scarf 42 is corresponding with the pushing part 211 of described pushing punching pin 20; Offer a fixing hole 43 on the left side wall of forming slide 40.

Described return mechanism 50 is installed between this die shoe and the forming slide 40, comprises a fixed head 51, fixedly a spiral pin 52 and a spring 53; Fixed head 51 is fixed on the die shoe position near forming slide 40 left sides, has a square substrate 511, and substrate 511 centers offer a through hole 512 that runs through this substrate 511; Fixedly spiral pin 52 has cylindrical shank 521 and circular pegs cap 522; Wherein fixedly spiral pin 52 cover upper springs 53, pass the through hole 512 of fixed head 51 and be fixed in the fixing hole 43 in forming slide 40 left sides, spring 53 is compressed between pin cap 522 and the fixed head 51.

See also Fig. 3 and Fig. 4, when carrying out the product punching press, patrix moves down, and drives the scarf 42 of the pushing part 211 extrusion modling slide blocks 40 of pushing punching pin 20, makes forming slide 40 slide into the lower surface of strip 80; Take off the upper surface that is pressed on strip 80 under 30 of the parts of material, thus strip 80 is fixed in the mould; And then, finish the punch forming action by moulding punching pin 10 punching press strips 80.

See also Fig. 5 and Fig. 6, patrix moves up, and drive pushes punching pin 20 and takes off and expect to move on part 30 together; Forming slide 40 is below strip 80 is glided out in the effect of spring 53 and make strip 80 unhinderedly withdraw from Stamping Area, thus beginning next round punching production.

Stamping Area is stretched into and withdrawed to the utility model diel by forming slide 40, and the punch forming that can finish product does not smoothly hinder strip 80 turnover moulds again, guarantees the continuity and the accuracy of producing, and then enhance productivity.
