Abstract

"RESPIRADOURO DE MOLDE". Trata-se de um respiradouro para um molde que tem uma cavidade de molde que compreende um elemento de válvula alojado dentro de uma camisa de corpo principal e móvel de maneira recíproca nela em uma direção axial entre as posições aberta e fechada. A camisa é montada dentro de uma parede do molde e contém um agente de expansão tal como silicone. Um aumento na temperatura do molde faz com que o agente de expansão expanda e mova o elemento de válvula da posição fechada para a posição aberta. Uma ranhura anular externa é proporcionada dentro da camisa para receber o material deslocado da parede do molde conforme a camisa é inserida por pressão na parede do molde. Resulta um encaixe firme da camisa dentro da parede do molde. A camisa e a válvula são configuradas para permitir que o ar escape na posição aberta. O elemento de válvula é movido para a posição fechada pelo material dentro da cavidade do molde fazendo pressão contra o elemento de válvula.
