Abstract
Изобретение относится к литейному производству по получению изделий в основном из термопластичного полимера литьем под давлением, преимущественно толстостенных изделий. Техническое решение изобретения может также распространяться и на получение изделий из других материалов. Задачей изобретения является получение технического результата по предотвращению образования усадочных раковин внутри толстостенных отливок путем управления процессом застывания их материала. Поставленная задача решается тем, что способ получения толстостенных отливок из полимерного материала, заключающийся в том, что в литьевой форме преобразуют расплав полимерного материала в отливку (8), которая извлекается оттуда и застывает, имеет отличительные признаки: в процессе застывания отливки (8) ее принудительно отверждают с различной скоростью. Варианты выполнения изобретения: применена литьевая форма с изменяемым объемом своей полости, в которой расположен подвижный поршень с возможностью в процессе литья отодвигаться назад, обеспечивая перемешивание расплава полимерного материала; изменяемый объем полости литьевой формы обеспечен за счет того, что литьевая форма содержит подвижный поршень; извлекают отливку из литьевой формы путем ее выталкивания подвижным поршнем; принудительное отверждение отливки с различной скоростью осуществляется на основе теплоизоляции некоторых ее поверхностей, например торцов, с помощью теплоизоляционного материала (17); принудительное отверждение отливки с различной скоростью осуществляется на основе подогрева некоторых ее поверхностей; принудительное отверждение отливки с различной скоростьюThe invention relates to foundry for the production of products mainly from thermoplastic polymer by injection molding, mainly thick-walled products. The technical solution of the invention may also extend to the receipt of products from other materials. The objective of the invention is to obtain a technical result for the prevention of the formation of shrink holes in the thick-walled castings by controlling the process of solidification of their material. The task is solved by the fact that the method of obtaining thick-walled castings from polymeric material, which consists in converting the melt of polymeric material into a mold (8), which is extracted from there and solidifies, has distinctive features: forcibly cured at different rates. Embodiments of the invention: applied injection mold with a variable volume of its cavity, in which a movable piston is located, with the possibility of moving backwards during the casting process, providing mixing of the polymer melt; variable volume of the mold cavity is provided due to the fact that the injection mold contains a movable piston; remove the casting from the mold by pushing it with a movable piston; forced curing of the casting at different speeds is carried out on the basis of the thermal insulation of some of its surfaces, for example, the ends, with the help of the thermal insulation material (17); forced curing of the casting at different speeds is carried out on the basis of heating of some of its surfaces; forced curing of castings at different speeds
