Moulding station for deep drawing of hot thermoplastic sheet using differential pressure pressure-actuated clamping units securing guide bars of moulding components, on reaching moulding position, in modification of vacuum forming machine

摘要

This deep drawing machine for thermoplastic has a novel moulding station, where a plastic panel or sheet section is heated and deformed under differential pressure. The station includes clamping units and a rising and falling table for the deep drawing mould, with guides and a drive. A pressure bell or mould half is located opposite, i.e. above the table. The clamping units (14) grip and secure the mould table (11) guide bars (12), once it has risen to the moulding position
