Abstract

The invention discloses a structure and an operation method for solving the problem of transcribing foil wrinkles of a high-convex die core, comprising a front fixing plate and a rear fixing plate adapted to the front fixing plate, and the rear fixing plate is provided with a rear die core. A rubber ring is arranged between the rear mold core and the rear fixing plate, and a movable mold core frame is set on the outer wall of the rear mold core. Air cylinders are arranged on both sides of the movable mold core frame. A sealing ring is arranged between the end face of the die core frame and the end surface of the foil pressing plate. The foil pressing plate is fixed on the movable die core frame. The cylinders on the left and right sides of the movable mold core are matched with the high convex end face of the rear mold core and the inner concave end surface of the front mold core. In order to avoid the problem that the high punch core structure will be wrinkled when the transfer foil is wrapped, and the good product cannot be produced after injection molding.

Description

A kind of structure and its operating method solving high convex mode transcription foil gauffer

Technical field

The present invention relates to decoration technique inside mold field, specially a kind of structure for solving high convex mode transcription foil gauffer and Its operating method.

Background technique

IMR (In-MouldDecoration by Roller) decoration technique inside mold is by decorative pattern and functional pattern Be printed on paper tinsel film (film) by high accuracy prints machine, by it is high-accuracy send foil device by foil be sent into moulding mould special in into After row is accurately positioned, high temperature and high pressure through jetting plastic raw material are by the surface of the pattern transfer in paper tinsel film to plastic cement products. IMR film is with light, translucency is good, bright-coloured bright color and high brightness the metal-like amount of can be widely applied to is big, high extra price Product of value, such as mobile phone, digital camera, the periphery 3C commodity, MP3, mouse, DVD panel and minaudiere etc..

The mold that current IMR technique uses, which is used, is arranged suction hole in front cavity border, and transcription foil is drawn onto preceding die cavity, Because institute's injecting products are in irregular shape, so when compressing transcription foil, compaction degree is undesirable, so that transcription foil still can when compressing There are gauffers, and product surface after injection molding is caused to have gauffer, influence the presentation quality of product, are unable to satisfy product requirement.

Summary of the invention
