PURPOSE:To make the field work efficient by a method wherein standard and auxiliary blocks of small size and light weight are employed and thereby positioning of an insert die, setting of a metal mold and disassembling work therefor are facilitated. CONSTITUTION:Standard blocks 12 and 12' are fitted in notch parts 11 and 11' provided along standard lines 10 and 10' on a metalmold fitting plate 1, while auxiliary blocks 16 and 16' are fitted in notch parts 15 and 15' spacing (d) between them positioned on the outside of lines 13 and 13' corresponding to the edges where an insert die 5 is scheduled to be placed. After two sides of the insert die 5 which cross at a right angle to each other are made to contact with the standard blocks 12 and 12', wedges 19 and 19' are pressed in the gaps between the other edge of the insert die 5 and the auxiliary blocks 16 and 16', thereby the insert die 5 being fixed. This facilitates the positioning of the insert die and makes it unnecessary to employ a heavy and expensive matrix, thus a light, inexpensive and easy-to-handle device is obtained. |
