PROBLEM TO BE SOLVED: To upgrade the mechanical strength by fitting a forward support plate and a backward support plate which are connected together with an auxiliary tie bar, to a main tie bar and also fitting an intermediate support plate, in a freely slidable manner, to the main and the auxiliary tie bar to constitute a support mechanism for an injection device. SOLUTION: A mold setting plate 2 and a back plate 3 are supported by a pair of main tie bars 4a, 4b arranged at symmetrical positions on both sides to a screw, so that the mechanical strength of both plates 2, 3 are ensured. A forward support plate 6 and a backward support plate 7 are symmetrically positioned on both sides to the screw and are connected with a pair of auxiliary tie bars 5a, 5b arranged at different positions from the main tie bars 4a, 4b so that the mechanical strength of both plates 6, 7 is ensured. Consequently a trouble such as the inclination of both mold setting plate 2 and injection device Mi from their normal positions is shot and thus the endurance of the whole injection device Mi is enhanced and the failure is prevented from occurring. The main tie bars 4a, 4b and the auxiliary tie bars 5a, 5b serve as functional elements, so that this combination usage contributes to saving on the manufacturing cost.
