PURPOSE:To eliminate the connecting line of resin by improving the arrangement of a gate for a television cabinet. CONSTITUTION:In the molding mold of a cabinet for television, two-point gate is provided within the distance of 60mm. Runners 11, gates 12, a cavity 13 and guide pins 15, which are positioning pins between the fixed side and the movable side of a movable mold 14, can be used for the flow passageway of molding material, therefore, the function of them mold is the same as a conventional mold. However, a pitch between an upper gate (a) and the upper gate (b) as well as a pitch between a lower gate (c) and the lower gate (d) are changed from 200m/m pitch to 60m/m pitch, therefore, weld lines will never be generated on the part A and the part B in the cavity 13.
