Claims

[Scope of Claim for Utility Model Registration] A movable platen is supported by a tie bar fixed to a fixed platen so as to be movable in the axial direction, and the movable platen is attached to an end housing whose axial position can be adjusted with respect to the tie bar □. In a mold thickness adjustment device of a toggle type mold clamping mechanism, which is connected by a toggle mechanism and adjusts the distance between a fixed platen and a movable platen by adjusting the fixing position of the end housing in the tie bar axial direction, -end When hydraulic pressure is supplied to the inner diameter part, a gap is formed between the cylinder, which is provided to move integrally with the housing, the piston, which is integrally formed with the tie bar and inserted into the cylinder, and the tie bar, and the inner diameter The toggle type is characterized by having a cylindrical member that is tight-fitted to the tie bar when the hydraulic pressure is discharged from the end housing, and a fixing member that restrains the cylindrical member from moving in the axial direction of the tie bar with respect to the end housing. Mold thickness adjustment device for mold clamping mechanism.
