Abstract

"MéTODO E MáQUINA DE MOLDAGEM POR DISPARO PARA A FABRICAçãO DE, PARTES DE MOLDE, TAIS COMO MACHOS DE FUNDIçãO, PARA MOLDES DE FUNDIçãO PARA A FUNDIçãO DE METAL DERRETIDO". A presente invenção refere-se a um método para a fabricação de partes de molde, em particular, de machos de fundição, para moldes de fundição para a fundição de corridas de metal derretido, em que, em uma máquina de moldagem por disparo (1), com a ajuda de elementos de enchimento, tais como bocais de disparo (8) e uma coifa de disparo (6), molde de material (F) contendo um agente aglutinante inorgânico é enchido na cavidade (12) de uma ferramenta de molde (10), que determina o formato da parte de molde (k) que é para ser fabricada, em que, o calor é fornecido ao material de molde (F) enchido na ferramenta de molde (10), sobre um período de endurecimento, a fim de solidificar o material de molde (F) devido à extração de umidade, e em que, durante o período de endurecimento, pelo menos os elementos de enchimento (6,8) da máquina de moldagem por disparo (1), que contém o material de molde (F), e que estão em uma posição de espera durante este período de endurecimento, e são aquecidos concomitantemente pelo calor radiante emitido pela ferramenta de molde (10), são mantidos a um nível de conteúdo de umidade que evita a solidificação do material de molde (F). Desta maneira, as partes de molde para moldes de fundição podem ser fabricados com segurança e com incidência de defeitos reduzida a partir de um material de molde contendo um agente aglutinante inorgânico."METHOD AND MACHINE FOR SHOOTING FOR THE MANUFACTURING OF MOLD PARTS SUCH AS CASTING MESTS FOR MOLDING MOLDS". The present invention relates to a method for the manufacture of mold parts, in particular foundry cores, for foundry molds for molten metal race casting, wherein in a firing molding machine (1) ), with the aid of fillers such as firing nozzles (8) and a firing hood (6), mold material (F) containing an inorganic binder is filled into the cavity (12) of a mold tool (10), which determines the shape of the mold part (k) to be manufactured, wherein heat is supplied to the mold material (F) filled in the mold tool (10) over a hardening period, in order to solidify the mold material (F) due to moisture extraction, and wherein during the hardening period at least the filler elements (6,8) of the firing molding machine (1) containing the mold material (F), and which are in a holding position during this hardening period and are concomitantly heated by the radiant heat emitted by the mold tool (10), are maintained at a moisture content level which prevents solidification of the mold material (F). In this way, mold parts for casting molds can be manufactured safely and with reduced defect incidence from a mold material containing an inorganic binder.
