Abstract
The utility model relates to a precise punching die of ultrathin plastic sheets. Guiding of inner guiding posts are added into an ordinary punching die, the four inner guiding posts are respectively inserted in through holes which are formed by a punch fixing plate and a discharging plate, and the top ends of the four inner guiding posts are abutted against the lower end surface of an upper die, a fixed mode of transition fit of the inner guiding posts and a punch is changed into a fixed mode of clearance fit, namely the inner guiding posts and the punch are in the clearance fit with a fixed plate, the inner guiding posts and the punch are in the transition fit with the discharging plate, stability of guiding precision of the inner guiding posts is guaranteed, the punch is enabled to carry out high-precision punching, when the ultrathin plastic sheets are placed on a special die, round holes, abnormal-shaped holes and hole in other shapes can be punched, the precision of the round holes, the abnormal-shaped holes and holes in other shapes can reach less than +/-0.03mm, the percent of pass can reach more than 98%, the precision of punching products and quality of the punching products are greatly improved, and the precise punching die of the ultrathin plastic sheets is applicable to demands of mass scale production.
Description
Technical field
The utility model relates to a kind of die cutting die of plastic sheet, particularly a kind of accurate punching mould of super-thin plastic sheet material.
Background technology
Usually the punching products of super-thin plastic sheet material is to use general die cutting die to carry out die-cut, about its precision ± 0.1mm, but its die-cut precision does not satisfy client's quality requirement, and for having improved product quality, so designing and developing of the accurate punching mould of super-thin plastic sheet material is necessary.
Summary of the invention
Needs in view of present actual production, the utility model provides a kind of accurate punching mould of super-thin plastic sheet material, concrete technical scheme is a kind of accurate punching mould of super-thin plastic sheet material, comprise part of the upper die and part of the lower die, the part of the upper die comprises again guide pin bushing, cope match-plate pattern, punch fixing plate, stripper, drift and spring, the part of the lower die comprises again lower bolster, ball guide pillar parts, backing plate, concave template, the vacuum suction connector, alignment pin, it is characterized in that: the part of the upper die also comprises inner guiding post, the part of the upper die is connected to four guide pin bushings and is fixed four jiaos of places, lower surface at cope match-plate pattern by being full of, punch fixing plate is fixed in the middle of the cope match-plate pattern, and four springs after being put in four blind holes on the punch fixing plate pass through stripper and punch fixing plate
DischargingScrew connects, and several drifts and four inner guiding posts are inserted in respectively in the through hole of composition of punch fixing plate and stripper and the top withstands on the lower surface of cope match-plate pattern; The part of the lower die is connected to four ball guide pillar parts and is fixed four jiaos of places, upper surface at lower bolster by being full of, and backing plate, concave template are screwed in the middle of lower bolster successively by alignment pin; Two vacuum suction connectors are threaded in the concave template rear end face; Part of the upper die and part of the lower die insert respectively to become matched in clearance to be connected in four guide pin bushings and make cope match-plate pattern and concave template on a central vertical axis by four ball guide pillar parts.Drift and inner guiding post and punch fixing plate precision matched in clearance, with stripper be interference fits.
The beneficial effects of the utility model are, the method for die cutting processing ease, product orientation is accurate, can go out precision can reach ± 0.03mm is with shapes such as interior circular hole, profiled holes, qualification rate can reach more than 98%, improve greatly the precision of punching products and the quality of product, be fit to the needs of large-scale production in enormous quantities.

The specific embodiment
Shown in Fig. 1-7, the part of the upper die is connected to four guide pin bushings 1 and is fixed four jiaos of places, lower surface at cope match-plate pattern 2 by being full of, punch fixing plate 3 is fixed in the middle of the cope match-plate pattern 2, after four springs 7 are put in four blind holes on the punch fixing plate 3 stripper 4 and punch fixing plate 3 are connected by unloading bolt, four drifts 5 and four inner guiding posts 6 are inserted in respectively in the through hole of composition of punch fixing plate 3 and stripper 4 and the top withstands on the lower surface of cope match-plate pattern 2, drift 5 and inner guiding post 6 and punch fixing plate 3 precision matched in clearance, be reduced to monolateral 0.005mm for interference fits and with guiding accuracy from general monolateral 0.02mm with stripper 4, its guiding accuracy is greater than the monolateral 0.01mm of the quality of fit of drift.The part of the lower die is connected to four ball guide pillar parts 9 and is fixed four jiaos of places, upper surface at lower bolster 8 by being full of, and backing plate 10, concave template 11 are screwed in the middle of lower bolster 8 successively by alignment pin 13; Two vacuum suction connectors 12 are threaded in concave template 11 rear end faces; Part of the upper die and part of the lower die are inserted respectively four guide pin bushings, 1 interior one-tenth matched in clearance by four ball guide pillar parts 9 and are connected and make cope match-plate pattern 2 and concave template 11 on a central vertical axis.
Because common die cutting die has increased the guiding of inner guiding post, the fixed form of inner guiding post and drift changes matched in clearance into by original interference fits, be that inner guiding post and drift and fixed head are matched in clearance, inner guiding post and drift and stripper interference fits, guaranteed the stability of the guiding accuracy of inner guiding post, it is die-cut to make drift can carry out high accuracy, the super-thin plastic sheet material is put into just can go out precision on the particular manufacturing craft and can reach ± 0.03mm with the shape such as circular hole, profiled holes.
