How to adjust the injection molding machine

1, install the mold
A. Measuring the thickness of the mold to estimate the stroke of the ejector pin;
B. Measuring the distance between the surface of the mold and the ejector plate;
C. The hand-operated machine hinges to straighten and lock the mold;
D. The mold adjustment device is twisted and adjusted to the distance between the plate and the template until the distance is slightly thicker than the mold, and the mold adjustment device is twisted;
E. Operate the mold by hand until it is finished;
F. Retract the needle by hand until the oil pressure thimble is completely retracted;
G, the stop mold is installed on the board;
H, the mode and mold speed and pressure adjustment between 30-50% (too high);
I. The machine clamping machine hinge is fully extended; the mold is installed at the side of the mold;
G, the machine operates the template to retreat a little to make the mold;
K, stop and then tighten the mold fixing screw machine to try to lock the mold to adjust the mold, clamping speed and pressure; L, then adjust the closing stroke and the electric block to make the mold and mold lock smooth
M, stop adjusting the position of the thimble before the end position, so that the thimble position is in the ejector needle stroke, the thimble stroke is shortened, the speed is increased, and the ejector speed is too high;

2, clamping force adjustment
A, hand-operated mold straight to start the mold adjustment device to reduce the mold thickness production clamping force off the mold adjustment device clamping mold thickness reduction and production lock mold force than the mold thickness reduction too can lock the mold recommended progressive reduction mode thick
B. Repeat the first step until the hinge and the template joint (Green column) produce enough clamping force to stop the clamping cylinder. Working pressure hydraulic system pressure gauge to see the thrust generated by the clamping cylinder and the working pressure ratio in the cylinder. The working pressure of the clamping force clamping cylinder and the higher the pressure, the more the clamping force
C, the general adjustment of the clamping force is enough to prevent the injection of rubber to produce a blunt, that is, the clamping force should be too high to avoid the deformation of the mold and the weight of the hinge.”
