Plastic part forming die with precise positioning structure

Abstract

The utility model discloses a kind of plastic part forming mould with accurate positioning structure, it is related to plastic forming mould technical field, to solve the problem of traditional mould positioning precision deficiency, lack of dynamic correction ability. The mould includes bottom plate, fixed lower die holder and vertical plate on bottom plate, lower die holder sets die, guide pillar, guide pillar and the sliding fit of guide bushing hole of upper die holder, upper die holder installs movable die;Servo electric cylinder connection push plate on vertical plate, push plate front end has symmetrical semicircular type convex strip, back face support plate installs laser displacement sensor, bottom plate is equipped with reference block by support, sensor detection end is opposite reference block. Guide bushing preliminary orientation when mould clamping, after mould clamping, sensor detects the distance between push plate and reference block, if there is deviation, servo electric cylinder drives push plate, and dynamic correction is carried out to movable die and die by convex strip, and positioning deviation is controlled within 0.002mm. The mould positioning precision is high, stability is strong, adapts precision plastic part forming, and structure is simple, maintenance is convenient.
