Abstract

Maquina mejorada para compactación de moldes de arena por impacto de aire u onda expansiva. La máquina, que cuenta con un calderín de presión (1) capaz de suministrar una corriente de aire de soplado a través del difusor (2) hacia la caja de moldeo (3), centra sus características en un sistema valvular específico según el cual a la embocadura (9) del calderín (1) y con la colaboración de un marco soporte (8), se fija un cuerpo valvular (7), tubular, al que a su vez se solidariza el difusor (2), definiendo este conjunto, con un amplio núcleo central (15), un paso periférico (16) para salida del aire en el que se establece un asiento valvular interno (14) para una membrana tubular (11) fijada por sus zonas marginales a las zonas marginales del cuerpo valvular (7), definiéndose por fuera de ella una cámara envolvente (12) que, al ser presurizada, provoca la estrangulación de la membrana (11) contra el asiento (14) y el consecuente cierre valvular. La apertura de la válvula (11-14) determina,a través del difusor (2), un chorro de aire que se concentra fundamentalmente sobre la zona perimetral de la caja de moldeo (3), mejorando la compactación de la arena (5). Figura 1.Improved machine for compacting sand molds by impact of air or blast wave. The machine, which has a pressure boiler (1) capable of supplying a flow of blowing air through the diffuser (2) to the molding box (3), focuses its characteristics on a specific valve system according to which the mouth (9) of the boiler (1) and with the support of a support frame (8), a valve body (7) is fixed, tubular, which in turn supports the diffuser (2), defining this set, with a wide central core (15), a peripheral passage (16) for air outlet in which an internal valve seat (14) is established for a tubular membrane (11) fixed by its marginal zones to the marginal areas of the valve body (7), an outside chamber (12) being defined on the outside which, when pressurized, causes the throttling of the membrane (11) against the seat (14) and the consequent valve closure. The opening of the valve (11-14) determines, through the diffuser (2), an air jet that is mainly concentrated on the perimeter area of the molding box (3), improving the compaction of the sand (5) .
