Abstract

The invention discloses a stretched film assembly for material forming, which comprises a stretched film, a stretched film support, a tensioned film clamping support, a mold and an operation table. The tensioned membrane is a material that can be tensioned and provides out-of-plane pressure in a tensioned state. The tensioned membrane clamping bracket tensions the tensioned membrane and fixes it on the operating platform. The tensile film clamping bracket includes the first tensioning film clamping bracket and the second tensioning film clamping bracket; the tensioning film can be clamped and placed on the first tensioning film clamping bracket and the second tensioning film clamping bracket Between the brackets; the molding material can be placed on the working surface of the mold, and the tensioned film is pressurized to form the shape of the working surface of the mold; the clamping bracket is fixed by a clip; the mold is detachable. The invention also discloses a method for using a stretched membrane module for material forming. The invention has simple process, convenient feeding, low cost, and can flexibly adjust the product size and thickness without redesigning the mold, avoiding common compression molding Difficulties in venting and demoulding.

Description

technical field

[0001] The present invention relates to the field of mold manufacturing, in particular to a tensioned film assembly for material forming and a method for using the same. Background technique

[0002] Compression molding is a method of adding premix or prepreg between a metal female mold and a male mold to form a composite product. This method has a high degree of automation, high production efficiency, low cost, is suitable for mass production, and produces products with good appearance and high dimensional accuracy, so it is widely used. However, since this method needs to add premix or prepreg to the female and male molds, the filling amount of the premix or prepreg is strictly controlled, and too much or too little filling will cause various problems. or substandard products. In addition, since the premix or prepreg is in a closed or semi-closed space, during the molding process, it is necessary to carry out an exhaust operation, and strictly control the...
