Abstract

Апарат за леене на детайли от еластични материали, включващ леярска форма с кухини (гнезда) за еластичния материал, възел за впръскване на еластичния материал в кухините на леярската форма състоящ се от бездънен цилиндър с бутало и камера за еластичен материал, като между леярската форма и впръскващия възел е установена флексибилна пластина, както и приспособления за взаимно придвижване на леярската форма и впръскващия възел и нагревателни елементи, характеризиращ се с това, че флексибилната изолационна пластина е термоустойчива и е закрепена към цилиндъра на впръскващия възел, а крайната термоустойчива флексибилна изолационна пластина е закрепена към адаптатор, при което леярската форма е съставена от три пласта долен пласт, среден пласт и горен пласт, оформящи леярските кухини (гнезда) с оптимален брой секции. Патентните претенции са формулирани в 23 точки.
