Abstract

A molding method, equipment for carrying out said method and mold obtained by means of said method are disclosed. The method comprises obtaining at least two semi-molds (23, 24), wherein each semi-mold (23, 24) is obtained outside the axis of advance (3) by sand blowing by means of horizontal molding on a pattern plate (15, 16) which is located horizontally during said molding, said pattern plate (15, 16) defining an impression on one face of each semi-mold (23, 24). The method comprises rotating 90° and vertically facing said at least two semi-molds (23, 24) to one another by the faces incorporating the impression to define a cavity (26) which can be filled with the molten material of the part to be obtained. The molding equipment comprises at least a shooting chamber (4, 5) comprising a sand blowing chamber (20), located outside the axis of advance (3), wherein the semi-mold (23, 24) can be obtained and rotating means (27) for rotating the pattern plate (15, 16) with the semi-mold (23, 24) 90° for the vertical arrangement thereof and transferring means (6,7) for transferring the semi-mold (23, 24) to a semi-mold assembly area (8) provided in the mold axis of advance (3). The mold obtained comprises two semi-sand molds (23, 24) comprising an impression on one face, such that once facing one another by the face of the impression they comprise a casting basin (21) the volume of which is at least 15% of the volume of the cavity (26) defined by the facing impressions of both semi-molds (23, 24).
