How to solve the problem of leakage of injection molding machine normally?

1. It is proposed that the molds are equipped with positioning rings. Although there is no positioning ring, it will save its cost, but there is no positioning ring, which will not only cause hidden safety risks of glue leakage, but also lengthen the time of changing the mold when changing the mold. The cost of destroying the electric heating ring can save the expenditure of the positioning ring;
2. Immediately check whether the tightening screws of the turret are loosened and tightened; the corresponding verification method: before production, the hand-held tractor is held on the cylindrical shooting platform. When encountering the mold, whether the tactile nozzle and the mold gate sleeve are in the same parallelism You can also use a plastic paper pad on the mold glue mouth. After the nozzle meets the mold, withdraw it to see if the paper hole is consistent with the nozzle mouth;
3. Temporary precautions due to damage to the mold sprue bushing and nozzle mouth: Use soft metal materials such as copper pads on the mold sprue bushing. After opening the hole, put the copper sheet again on the mold mouth cover according to the previously held part, and use the nozzle to resist the production; permanent precautions: re-grind the relative gate sleeve or nozzle to make the gate sleeve The R angle of both the nozzle on the turret is leveled and touched to produce;
4. Leakage caused by mismatching of the R angle of the sprue bushing or nozzle. Remove the sprue bushing or nozzle to keep the R angle of the sprue bushing and the nozzle consistent.
