It comprises a base mold (1) that has four corner devices (2) that are evenly mounted on two lateral guides (3) arranged parallel to each other, with respect to which those corner devices (2) can move in longitudinal directions to along the aforementioned lateral guides (3) by means of longitudinal spindles (8), all this in order to be able to regulate the longitudinal distance 5 between the corner devices (2) according to the distance between constituent testers (4a) of the minor side walls of a box (4).

A su vez, los extremos de las guías laterales (3) están acopladas en unas barras transversales (5), de forma que esos extremos de las guías laterales (3) están conectados a unos cabezales (6) con perforaciones roscadas en las que se acoplan dos 10 husillos transversales (7), cuyo giro regula una distancia transversal existente entre las guías laterales (3) y por lo tanto entre los pares de dispositivos de esquina (2) de acuerdo a la distancia existente entre unos costados (4b) constitutivos de las paredes laterales mayores de la caja (4) a conformar. In turn, the ends of the lateral guides (3) are coupled in transverse bars (5), so that those ends of the lateral guides (3) are connected to heads (6) with threaded holes in which couple two 10 transverse spindles (7), whose rotation regulates a transverse distance existing between the lateral guides (3) and therefore between the pairs of corner devices (2) according to the distance between constituent sides (4b) of the major side walls of the box (4) to be shaped.

El molde base (1) se complementa con un macho empujador (no representado en las 15 figuras) que se encarga de iniciar la conformación de la caja (4) cuando desplaza una lámina troquelada de cartón sobre un espacio central del molde base (1) delimitado entre los cuatro dispositivos de esquina (2), de forma que en la operación de ese desplazamiento del macho empujador (8) se inicia la conformación de la caja (4) dentro del molde base (1). 20 The base mold (1) is complemented by a pusher male (not shown in the 15 figures) that is responsible for starting the formation of the box (4) when moving a die-cut cardboard sheet over a central space of the base mold (1) delimited between the four corner devices (2), so that in the operation of this displacement of the pusher male (8) the formation of the box (4) inside the base mold (1) begins. twenty

Cada dispositivo de esquina (2) cuenta con un chasis (9) unido solidariamente a una pieza extrema (10) acoplada en la respectiva guía lateral (3), de forma que a través de esta pieza extrema (10) se desplaza el conjunto del dispositivo de esquina (2) sustentado por el chasis (9).
