Abstract

La presente se relaciona con un procedimiento de fundición para obtener piezas provistas de cavidades interiores precisas, cuyas cavidades se obtienen colocando dentro de un molde o coquilla, destinados a recibir el metal fundido, uno o más machos hechos de arena u otro material, y en el cual se utiliza un macho principal, realizado en un caja de machos especial, junto con uno o más machos secundarios destinados a estar relacionados con dicho macho principal, que comprende las siguientes etapas: revestimiento al menos de un macho secundario, solamente en las zonas y por el grosor del patrón con una capa de material destinado a disolverse en contacto con el metal fundido; inserción de los machos secundarios pre-revestidos dentro de una caja de machos principal aún por ser moldeada; moldeo de la caja de machos principal; e inserción del conjunto monolítico obtenido en la etapa anterior, que consiste en el macho principal, los machos secundarios y el material de revestimiento que los mantiene firmemente conectados, dentro del molde o coquilla destinado a recibir el metal fundido. Los machos a ser revestidos también pueden formarse por las inserciones huecas hechas de material resistente al calor, llenadas con resina polimerizada y arena, donde la cavidad represente al patrón del macho. Reivindicación 11: Caja de machos principal para el procedimiento de fundición de acuerdo con cualquiera de las reivindicaciones 4-10, caracterizada porque solamente consiste en dos partes destinadas a ser cerradas una sobre la otra, por lo cual es libre de muescas y por consiguiente, de piezas móviles adaptadas a realizar el ahusamiento, y que muestra asientos e impresiones negativas (20', 20'') para recibir y bloquear en posición los machos secundarios pre-ensamblados con el material de revestimiento. Reivindicación 12: Matriz para el revestimiento de los machos de los conductos de admisión y escape en el procedimiento de fundición de la tapa de cilindro de motor de acuerdo con las reivindicaciones 5-10, caracterizada porque está provista de pins móviles cilíndricos (16, 17) destinados a realizar asientos (16', 17') dentro del material de revestimiento para las guías (16'', 17'') de las válvulas de toma y expulsión. Reivindicación 14: Tapa de cilindro de motor caracterizado porque encastra al menos una inserción hueca (23) hecha de metal u otro material resistente al calor, cuyo interior forma el diseno del correspondiente conducto de admisión y escape.This is related to a casting procedure to obtain parts with precise interior cavities, whose cavities are obtained by placing inside a mold or shell, intended to receive molten metal, one or more males made of sand or other material, and in which uses a main male, made in a special male box, together with one or more secondary males intended to be related to said main male, which comprises the following stages: coating at least one secondary male, only in the areas and by the thickness of the pattern with a layer of material intended to dissolve in contact with the molten metal; insertion of pre-coated secondary males into a main male box yet to be molded; molding of the main male box; and insertion of the monolithic assembly obtained in the previous stage, which consists of the main male, the secondary males and the lining material that keeps them firmly connected, within the mold or shell intended to receive the molten metal. The males to be coated can also be formed by hollow inserts made of heat-resistant material, filled with polymerized resin and sand, where the cavity represents the male's pattern. Claim 11: Main male housing for the casting process according to any one of claims 4-10, characterized in that it only consists of two parts intended to be closed one above the other, whereby it is free of notches and therefore, of moving parts adapted to make the taper, and showing seats and negative impressions (20 ', 20' ') to receive and lock in position the pre-assembled secondary males with the lining material. Claim 12: Matrix for lining the males of the intake and exhaust ducts in the casting process of the engine cylinder cover according to claims 5-10, characterized in that it is provided with cylindrical movable pins (16, 17 ) intended to make seats (16 ', 17') inside the lining material for the guides (16 '', 17 '') of the intake and ejection valves. Claim 14: Engine cylinder cover characterized in that it embeds at least one hollow insert (23) made of metal or other heat-resistant material, the interior of which forms the design of the corresponding intake and exhaust duct.
