Expulsores y remetido<\/h1>\n

Marcas del expulsor<\/h2>\n

Las marcas de los expulsores en las piezas fundidas est\u00e1n compuestas por patillas m\u00f3viles que expulsan las piezas del molde. El n\u00famero y la situaci\u00f3n de los expulsores, para conseguir la producci\u00f3n m\u00e1s econ\u00f3mica, variar\u00e1 seg\u00fan el tama\u00f1o y la complejidad de la pieza fundida, as\u00ed como tambi\u00e9n de otros factores.<\/p>\n

Situaci\u00f3n del expulsor<\/h2>\n

La situaci\u00f3n del expulsor se realizar\u00e1 a criterio del moldeador de acuerdo con las especificaciones determinadas por el cliente.<\/p>\n

Marcas aceptables del expulsor<\/h2>\n

La mayor\u00eda de marcas de expulsor en las piezas fundidas puede subirse 0,38 mm o rebajarse 0,38 mm como m\u00e1ximo. Las marcas del expulsor est\u00e1n rodeadas por una rebaba de metal.<\/p>\n

Si el uso final lo permite, la rebaba del expulsor no se extraer\u00e1. En los casos en los que no sea posible, la rebaba del extractor deber\u00e1 aplastarse o alisarse.<\/p>\n

Note – <\/span>La eliminaci\u00f3n por completo de las marcas y las rebabas del expulsor por maquinado o raspado manual deber\u00e1 especificarse s\u00f3lo cuando las necesidades justifiquen el gasto que implica la realizaci\u00f3n de esta tarea extra.<\/p>\n

Requisitos de dise\u00f1o<\/h2>\n

Todas las paredes de las piezas fundidas normalmente deben ser verticales al plano de separaci\u00f3n del molde que necesite remetido o vaciado. Este remetido no es constante. Variar\u00e1 seg\u00fan la aleaci\u00f3n utilizada y la profundidad de la pared. El remetido necesario en las paredes exteriores es la mitad del necesario en las paredes interiores.<\/p>\n

Una buena pol\u00edtica es especificar un gran \u00e1ngulo de remetido donde sean tolerables \u00e1ngulos pr\u00e1cticos pero de un grado o menos.<\/p>","protected":false},"excerpt":{"rendered":"
