Abstract

PURPOSE: To make the mounting and dismounting of the captioned device to and from the piston rod easy by constituting the device by the body on the injection piston rod side and the head on the plunger rod side removable from this and specifying the centroid position of the foregoing device thereby preventing the inclination of the deivce with respect to the piston rod.
CONSTITUTION: One 18a of a stopper ring is fitted into the annular groove at the end part of a piston rod 1b of a cold chamber machine or the like and the coupling body 10a is put in the position relation of Fig. B. Next, an independent member 12b of the same shape as that of a hemi-cylindrical fixing part 12a is opposed to said part and is bolted thereto. An intervening piece 33 is inserted into the circular hole 23 of the annular part 11 of the body fixed to the rod 1b. On the other hand, a head 10b is beforehand fitted to the root end of the plunger rod 3 so that an enlarged circular groove 27 fits into its enlarged part 3a. Thence, the head 10b is approached to the body 10a and is bolted thereto. In this way, the rods 1b, 3 are connected, in which case the centroid position of the coupling 10 is put closer on the injection cylinder device 1 side than the end face 1b1 of the rod 1b.
