Abstract
The invention relates to a plastic strip cold punching mold, which comprises an upper mold and a lower mold, wherein the upper mold is sheathed and connected with a guide post arranged on the lower mold through a guide sleeve arranged on the upper mold, a male mold is arranged on the upper mold, the upper mold consists of the guide sleeve, a mold handle, an upper mold seat, a male mold fixing plate and a male mold, and the lower mold consists of the guide post, a positioning plate, a female mold and a lower mold seat. Compared with the prior art, the plastic strip cold punching mold has the advantages that the male mold adopts the inclined plane design, the male mold is a sharp cutter blade, the contact area between a mold punching notch and a punching element is reduced, the cut surfaces of the plastic strips are smooth and flat, the mold completes the punching under the condition without a great load, the cutting quality of punching products is improved, and in addition, the service life of the mold is prolonged.
Description
Technical field
The present invention relates to a kind of cold-punching mold, especially relate to a kind of die-cut cold-punching mold of plastic strip that is used for.
Background technology
In the process of plastic strip, often adopt the die-cut method processing of cold-punching mold.The cold-punching mold of profiled plastic bar of the prior art; Normally the punch knife face is designed to the plane; Because consider the service life of mould, there are certain clearance in punch and die, after wearing and tearing after a while; The die-cut part section that comes out has phenomenons such as wire drawing, burr, has had a strong impact on the outward appearance and the size of product.
Summary of the invention
The object of the invention is exactly in order to overcome the defective that above-mentioned prior art exists a kind of plastic strip cold-punching mold to be provided, and makes the die-cut quality of plastic strip be improved and prolongs service life of mould.
The object of the invention can be realized through following technical scheme:
A kind of plastic strip cold-punching mold is characterized in that: this plastic strip cold-punching mold upper die and lower die constitute, the sheathed connection of guide pillar that described patrix is provided with on the guide pin bushing that is provided with and counterdie.
Described patrix comprises guide pin bushing, die shank, upper bolster, punch retainer and punch; Described upper bolster rear end is provided with two guide pin bushings; Described die shank is located at the upper bolster top; Described punch retainer is located at the bottom of upper bolster, is connected with upper bolster through patrix alignment pin and patrix fixed screw, and described punch is embedded the bottom at punch retainer.
Described convex mould surface is the inclination knife face.
Described counterdie comprises guide pillar, location-plate, die and die shoe; Described guide pillar is located at the rear end of die shoe; Described die is located at the top of die shoe, is fixed on the die shoe through the counterdie fixed screw, offers the charging aperture that connects before and after the twice on the die horizontal direction; Two following nibs are offered at the top, and described location-plate is plugged in the rear portion of charging aperture and is fixed on the die shoe through fixed screw.
The shape of described nib down is identical with punch.
Compared with prior art; Punch among the present invention is to adopt inclined design, and punch is sharp blade, and the punch die edge of a knife and stamping parts contact area reduce; The disconnected tangent plane of plastic strip is bright and clean concordant; Mould need not to have accomplished under the situation of heavy load very die-cut, and the disconnected quality of cutting of not only die-cut product is improved, and has prolonged the service life of mould.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the plan structure sketch map of counterdie.
Wherein: nib, 12-location-plate, 13-charging aperture, 14-die, 15-die shoe under 1-guide pin bushing, 2-die shank, 3-patrix fixed screw, 4-upper bolster, 5-patrix alignment pin, 6-punch retainer, 7-punch, 8-guide pillar, 9-counterdie fixed screw, 10-fixed screw, the 11-.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Embodiment
A kind of plastic strip cold-punching mold, its structure is as shown in Figure 1, comprises upper die and lower die, and upper die and lower die pass guide pin bushing 1 connection that is arranged on the patrix through the guide pillar 8 that is arranged on the counterdie.Patrix comprises guide pin bushing 1, die shank 2, upper bolster 4, punch retainer 6 and punch 7; The rear end of upper bolster 4 is provided with two guide pin bushings 1; Die shank 2 is located at upper bolster 4 tops, and punch retainer 6 is located at the bottom of upper bolster 4, is connected with upper bolster 4 through patrix alignment pin 5 and patrix fixed screw 3; The punch 7 of the given shape of offering according to process requirements is embedded the bottom at punch retainer 6; Punch 7 surfaces are the inclination knife face, and the inclined-plane edge of a knife of punch 7 moves downward along section, makes the profiled plastic bar punch out corresponding shape.The structure of counterdie is as shown in Figure 2; Comprise guide pillar 8, location-plate 12, die 14 and die shoe 15; Guide pillar 8 is located at the rear end of die shoe 15, and die 14 is located at the top of die shoe 15, is fixed on the die shoe 15 through three pairs of counterdie fixed screws 9; Offer the charging aperture 13 that connects before and after the twice on the horizontal direction of die 14; Two following nibs 11 identical with punch 7 shapes are offered at the top, and location-plate 12 is plugged in the rear portion of charging aperture 13 and is fixed on the die shoe 15 through fixed screw 10, and location-plate 12 can be regulated to control the degree of depth that special-shaped plastic strip inserts front and back.
Plastic strip is put into die 14 by charging aperture 13; Location-plate 12 is put into from charging aperture 13 rear ends and the fixing degree of depth that gets into the control plastic strip; Forcing press presses down die shank 2 makes upper bolster 4 press down along guide pillar 8; The punch 7 that is arranged on upper bolster 4 enters into the following nib 11 of corresponding die 7, and the plastic strip that is placed on the inside is die-cut into needed shape.
