Abstract

FIELD: production of hollow pieces out of thin sheets of thermoplast, for example, production of protective packing containers made of sheets of polyvinyl chloride, etc. SUBSTANCE: method provides, that upper plate of joint is heated up to given temperature, then sheet is gripped between plate and matrix. Sheet is pressed to plate of heating by air. After contact heating of place its negative pneumatic formation is exercised by compressed air fed through holes in upper plate. Then after cooling formed piece is taken out. EFFECT: improved process.

Изобретение относится к способам производства полых изделий из тонких листов термопласта, например защитных упаковочных контейнеров из листов поливинилхлорида и т.п. Способ заключается в том, что верхнюю плиту узла формовки нагревают до установочной температуры, зажимают лист между плитой и матрицей, прижимают лист к плите нагрева воздухом, после контактного нагрева места производят его негативное пневмоформование сжатым воздухом, подаваемым через отверстия в верхней плите. Затем отформованное изделие после охлаждения извлекают.The invention relates to methods for the production of hollow products from thin sheets of thermoplastic, for example, protective packaging containers from sheets of polyvinyl chloride, etc. The method consists in the fact that the upper plate of the molding unit is heated to the set temperature, the sheet is clamped between the plate and the die, the sheet is pressed to the air heating plate, after contact heating of the place, it is negatively formed by compressed air supplied through the holes in the upper plate. Then the molded product is removed after cooling.
