In the figure, reference numeral 1 denotes a fixed plate of an injection molding machine, which is integrally formed with a tubular portion 8 which constitutes a penetrating portion of the tie bar 6. The tubular portion 8 has a hollow portion which penetrates the tie bar 6 with a bolt 9. A mold clamping cylinder 2 having a hole 13a is attached. Mold clamping cylinder 2
Is a space between the cylinder 13 provided with a hollow hole 13a for penetrating the tie bar 6 and the cylinder 13 incorporated inside.
The ram 4 is movably inserted so as to form 14, and pressure oil is supplied to the space 14 from a hole 12 provided in the cylinder 13. 3 is bolt 13 to cylinder 13
Is a stopper flange that is fixed with the same flange 3 as the stopper of the ram 4 and the packing 10 attached to the cylinder 13.
Also serves as a presser foot. Reference numeral 7 is a flange fixed to the cylinder 13 with bolts 16, and the flange 7 is for pressing the packing 11 attached to the cylinder 13. Reference numeral 5 denotes a split nut, which is formed with a female groove or screw 5a that meshes with a male groove or screw 6a provided at the end of the tie bar 6. When the female groove or screw 5a and the male groove or screw 6a mesh with each other, the tie bar 6 Are fixed to the stationary platen 1.
