Abstract

FIELD: production of protective packing containers from sheets of polyvinylchloride. SUBSTANCE: the offered device includes die and plate of contact heating coaxial to die and provided with slotted hole for air supply. One part of plate of contact heating is made in form of removable plate to whose contact surface, antiadhesion material is applied. Removable plate is encircled over its entire height with hold-down frame made of heat-insulating material which makes it possible simultaneous clamping of thin sheet of thermoplast between removable plate and die and heat insulation of working surface of plate of contact heating, i.e., removable plate. EFFECT: higher efficiency. 5 cl, 1 dwg

Изобретение относится к устройствам, предназначенным для производства полых изделий из тонких листов термопласта, например защитных упаковочных контейнеров из листов поливинилхлорида и т.п. Устройство включает в себя подвижную в осевом направлении матрицу и расположенную соосно ей плиту контактного нагрева с щелевыми отверстиями для подачи воздуха. Часть плиты контактного нагрева выполнена в виде съемной плиты, на контактную поверхность которой нанесен слой антиадгезионного материала. Съемная плита по всей высоте окружена прижимной рамкой, выполненной из термоизолирующего материала, которая позволяет одновременно зажать тонкий лист термопласта между съемной плитой и матрицей, а также термоизолировать рабочую поверхность плиты контактного нагрева, т.е. съемной плиты.The invention relates to devices for the production of hollow products from thin sheets of thermoplastic, for example, protective packaging containers from sheets of polyvinyl chloride, etc. The device includes an axially movable matrix and a contact heating plate located coaxially with slotted openings for air supply. Part of the contact heating plate is made in the form of a removable plate, on the contact surface of which a layer of release material is applied. The removable plate is surrounded over its entire height by a clamping frame made of thermally insulating material, which allows you to simultaneously clamp a thin sheet of thermoplastic between the removable plate and the matrix, as well as thermally insulating the working surface of the contact heating plate, i.e. removable plate.
