Abstract

Máquina de moldeo con inyección de gas. Una máquina de moldeo con inyección de gas provista de una cavidad auxiliar formada en un costado de una cavidad para permitir que la resina fundida sea nebulizada y expulsada de la cavidad al inyectar gas a través de una puerta, teniendo la cavidad auxiliar un medio de control para cambiar libremente un área de la misma con el fin de alojar la resina a nebulizar durante la inyección del gas, evitándose así la formación de defectos en la superficie externa del producto moldeado y evitándose el inconveniente que suponen los acabados adicionales del producto moldeado después de la inyección del gas. Figura 3.
