Abstract

Matriz que consta de dos o más placas, esencialmente compuesta por un pistón de empuje del material a moldear, una placa de transferencia del caucho y alojamiento del pistón, una placa intermedia con cavidades de moldeo en ambas caras y una placa base con cavidades de moldeo en su cara superior y una cara lisa inferior. Las cavidades pueden estar distribuidas sobre la superficie en forma radial y/o ortogonal y están circunscriptas por un canal de profundidad adecuada para la descarga de aire que se requiere en el correcto proceso de fabricación de las piezas. Estas cavidades poseen pequenos canales horizontales de colada individual de material, que se encuentran interconectados en diferentes direcciones a los canales de transferencia vertical que atraviesan las placas con cavidades en sus caras. Las placas se encuentran guiadas por columnas o pernos cónicos para asegurar el correcto posicionamiento del pistón en el alojamiento de la placa de transferencia. En la placa de transferencia se alojan resortes para lograr una mayor presión de cierre entre las placas que forman la matriz. Las placas 2, 3 y 4 (de transferencia, intermedia y base respectivamente) se encuentran unidas en la parte posterior por medio de un sistema de bisagras para realizar su apertura durante el proceso de fabricación de las piezas; así mismo estas también poseen depresiones realizadas en sus ángulos de la cara frontal de modo que facilite por medio de una varilla metálica, que se utiliza a los fines de palanca, la apertura rápida de las placas y agilice la extracción del material. Este aparato puede contar con más placas a fin de obtener mayor producción del producto final.Matrix consisting of two or more plates, essentially composed of a push piston of the material to be molded, a rubber transfer plate and piston housing, an intermediate plate with molding cavities on both sides and a base plate with molding cavities on its upper face and a smooth lower face. The cavities can be distributed on the surface radially and / or orthogonally and are circumscribed by a channel of depth suitable for the discharge of air that is required in the correct manufacturing process of the pieces. These cavities have small horizontal channels of individual material casting, which are interconnected in different directions to the vertical transfer channels that cross the plates with cavities on their faces. The plates are guided by columns or conical bolts to ensure correct positioning of the piston in the transfer plate housing. In the transfer plate, springs are housed to achieve a higher closing pressure between the plates that form the matrix. The plates 2, 3 and 4 (transfer, intermediate and base respectively) are joined at the back by means of a hinge system to open during the manufacturing process of the pieces; they also have depressions made at their angles of the front face so that it facilitates by means of a metal rod, which is used for the purpose of lever, the rapid opening of the plates and expedites the extraction of the material. This device can have more plates in order to obtain greater production of the final product.
