Abstract

Задачей изобретения является изготовление усовершенствованных литьевых форм для металлического литья без повышения сложности изготовления. "Усовершенствованную" форму можно охарактеризовать тем, что она в течение продолжительного времени, в том числе при изменении или замене показателей качества, а значит по меньшей мере одного из многих свойств формовочного материала, сохраняет поверхность однородной твердости из формовочного материала. Для этого предложено изготовление из формовочного материала литейной формы для литья прочностью не ниже, чем у металлического литья. Гранулированную формовочную смесь загружают в качестве формовочного материала (41) в опоку (40). Формовочный материал (41) уплотняется внутри опоки (40) в формовочной машине над моделью (44), установленной на подмодельной плите (46). На первом этапе опоку (40) перемещают прессующим устройством (1) по первому рабочему пути до ограничителя хода на раме (13) головки (10) пресса. Во втором этапе подмодельную плиту (46) перемещают прессующим устройством по второму рабочему пути (s, s) в конечный пункт для упрочнения или уплотнения (изготовления) литейной формы из формовочного материала. Длина второго рабочего пути (s, s) изменяется в зависимости от формовочного материала преимущественно автоматическим способом - то есть, длина второго рабочего пути (s, s) изменяется (100, 102; 102') в зависимости от силы, определенной по окончании предыдущего упрочнения или уплотнения формовочного материала предыдущей литьевой формы вследствие изменения по меньшей мере одного свойства неуплотненного формовочного материала (41). Предложенная формовочная машина реализует вид регулирования твердости (регулирования прочности) формовочного материала (41) в уплотненной форме.The objective of the invention is the manufacture of advanced injection molds for metal casting without increasing the complexity of manufacturing. The “improved” shape can be characterized by the fact that it maintains the surface of uniform hardness of the molding material for a long time, including when changing or replacing the quality indicators, and therefore at least one of the many properties of the molding material. For this, it was proposed to manufacture a casting from a molding material for casting with a strength not lower than that of a metal casting. Granulated molding mixture is loaded as a molding material (41) in the mold (40). The molding material (41) is compacted inside the flask (40) in the molding machine above the model (44) mounted on the sub-model plate (46). At the first stage, the flask (40) is moved by the pressing device (1) along the first working path to the travel stop on the frame (13) of the press head (10). In the second stage, the sub-model plate (46) is moved by the pressing device along the second working path (s, s) to the final point for strengthening or compacting (manufacturing) the mold from the molding material. The length of the second working path (s, s) varies depending on the molding material predominantly in an automatic way — that is, the length of the second working path (s, s) varies (100, 102; 102 ') depending on the force determined at the end of the previous hardening. or compaction of the molding material of the previous injection mold due to the change in at least one property of the unconsolidated molding material (41). The proposed molding machine implements the type of hardness control (strength regulation) of the molding material (41) in a compacted form.
