Abstract

The invention discloses a V-process molding film drawing device. The V-process molding film drawing device comprises at least two film releasing rollers, a film drawing assembly and a film replacing assembly. When film covering is conducted, the free end of a film wound on any one of the film releasing rollers is connected with the film drawing assembly in a butt-joint manner, the film drawing assembly drives the film to slide relative to the corresponding film releasing roller, the corresponding film releasing roller releases the film, and then film laying is achieved; when one of the film releasing rollers completely releases the film, the film replacing assembly is started to move to the film releasing roller wound with the film and alternatively draws the free end of the film wound onthe film releasing roller to the film drawing assembly, the film drawing assembly continues to drive the film to slide in a reciprocating manner, therefore, automatic film releasing roller replacing is smoothly achieved, the artificial participation degree is reduced, the time of taking down and putting the film releasing rollers is shortened, and then the time of replacing the film releasing rollers is shortened; and in addition, at least two stations can achieve continuous alternate film releasing through the at least two film releasing rollers, the invalid working time is shortened, and thefilm releasing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of casting technology, in particular to a V-method molding film pulling device. Background technique [0002] The existing V-method molding process usually includes steps such as negative pressure coating of the pressure plate, spraying, box closing, sand filling of the sand box, turning over the box and lifting the mold, closing the mold and pouring, and stopping the pumping. In order to achieve mass production, it is usually necessary to lay the film with the help of a film-drawing device during negative-pressure lamination, so it is particularly necessary to optimize the structure of the film-drawing device. [0003] The existing film pulling device usually includes a film releasing reel and a film releasing support, and the film releasing reel rotates relative to the film releasing support, so as to release the wound film. In view of the limited length of the film stored in the film release reel, when a...
