Hot-static pressure molding apparatus

Abstract

The invention discloses a hot-static pressure molding apparatus, which includes: a pressurizing mechanism, which includes a weight, and a weight bearing board supporting the weight, the weight supplies a driving force downwardly, so that under gravity of the weight, the weight bearing board can move down in the vertical direction; a mold includes a pressing rod, a plurality of long side plates, and a top rod, wherein the long side plates are detachably and sealedly connected to form a cylinder of a sealed cavity; the top of the pressing rod is fixedly connected to the weight bearing board; thebottom of the pressing rod is stretched into the cylinder through an opening in the upper end of the cylinder to form a movable top of the sealed cavity; the top end of the top rod is stretched intothe cylinder through an opening in the lower end of the cylinder to form a fixed bottom of the sealed cavity; a heating mechanism includes a heating furnace, that is arranged in the sealed structure and can move vertically, and can be used for heating materials. The apparatus solves the problem that a hot-press shaping apparatus makes big noise, causes pollution on oil, causes fluctuation in pressure value, is limited in compression travel, cannot uniformly heat a mold, is high in energy consumption and cost and has difficulty in demolding.

Description

technical field [0001] The invention relates to the technical field of forming equipment, in particular to a hot static pressing forming device. Background technique [0002] Materials are an important basis for the development of science and technology. Polymer composite materials are closely related to people's lives and have increasingly become the focus of people's research. The performance of polymer resin composite materials formed by different components and different ratios is a research hotspot for the majority of researchers. Thermocompression molding is a commonly used resin composite molding method. The thermocompression molding device is an important molding equipment for researching polymer composite materials. It clamps the materials on the workbench and forms them by heating and pressing. At present, the existing hot press forming devices have the following problems: motor drive and hydraulic system drive are commonly used, which not only cause high noise bu...
