An adjustable mould consisting of matched mould members (1, 2) and to an object manufactured by employing the described mould. The casting or equivalent piece is produced in between the mould members. The male mould member (2) comprises the frame (3) and a number of mould elements (4) fitted therein. The female mould member (1) is provided with a front plate (21), a filling opening (22) and a frame (1b), whereinto the frame (3) of the male mould (2) is fitted. The male mould also comprises the locking plate (11) and the back plate (20). The mould elements (4) are elongate, quadratic in cross-section and matched to each other along the sides, and they are placed within the box-like frame (3). They can be moved by means of the adjusting screw (12) in the transversal direction with respect to the frame (3), their position can be adjusted and they can be locked into place by means of the tightening ledge (17). The mould is prepared for operation by placing the template in the filling space and by pressing the mould elements (4) against the template, whereafter the screws (12) are fastened to the locking plate (11) and the back plate (20) is installed. The tightening ledge (17) is tightened, so that the mould elements are pressed against each other. This kind of a mould is well suited for the manufacture of polystyrene packages. The surface structure of the mould is formed of steplike bulges, which correspond to the cross-sectional area of the the mould elements (4). |
