Изобретение относитс к литейному производству, в частности к изготовлению литейных форм прессованием .FIELD OF THE INVENTION The invention relates to foundry, in particular, to the manufacture of casting molds by pressing.
Многие известные способы получени литейных форм преследуют цель устранить переуплотнение смеси в надмодельном пространстве и недоуплотнение в углублени х модели и между модельноопочной оснасткой. Дл осуществлени этой цели рекомендуют два спосрба: выжимание излишка смеси из надмодельного пространства в полость контрмодели 1 или уменьшение количества рыхлой смеси (до начала уплотнени ) в надмодельном пространстве 2.Many well-known methods for producing casting molds are aimed at eliminating over-compaction of the mixture in the supra-model space and under-consolidation in the recesses of the model and between the model-top tooling. To accomplish this goal, two methods are recommended: squeezing the excess mixture from the supra-model space into the cavity of the counter-model 1 or reducing the amount of loose mixture (before compaction begins) in the model-like space 2.
Недостатки способа изготовлени литейных форм прессованием с вьшиманием излишка смеси в полость контмоделй - необходимость фрезеровки контрлада перед установкой полуформ на тележку конвейера и св занный сThe disadvantages of the method of making casting molds by pressing with the excess of the mixture poured into the cavity of the model is the necessity of milling the control panel before installing the molds on the conveyor carriage and associated with
этой операцией непроизводительный расход формовочной смеси. ,this operation unproductive consumption of sand. ,
Наиболее близок к предлагаемому способ выравнивани степени уплотнени смеси в надмодельном и околомодельном пространствах при прессовании плоской колодкой, но с профильной засыпкой смеси в модельноопочную оснастку перед уплотнением.Closest to the proposed method of leveling the degree of compaction of the mixture in the supra-model and near-model spaces when pressed with a flat block, but with a profile filling of the mixture in the model-heating equipment before compaction.
Этот способ не нашел применени , This method has not been applied.
10 так как практически невозможно Осуществить профилирование смеси со стороны контрлада путём ее свободной засыпки в модёльно-опочную оснастку.10, since it is almost impossible to carry out the profiling of the mixture from the side of the control by free filling it into the modular equipment.
Цель изобретени - получение равIS номерного уплотнени смеси по объему формы.The purpose of the invention is to obtain equal number sealing of the mixture by the volume of the form.
