211. Production of the reasons the mold ejector does not reset.
In injection molding, plastic mold on some small problems are inevitable, when the production of the mold when the top is not reset after the peak of the staff out for whatever reason, they need to how to solve it? Following on the causes of these problems and solutions to do a brief introduction:
After the top peak of the staff out of the mold does not reset the following reasons:
1) Mold problems in the production of plastic mold and the plunger with the plunger hole is not very good, tight lead after the top peak of the staff that does not reset; push rod holes in the production of the vertical degree of processing is also very good prone to not reset after ejection; then there are the mold ejector plate return spring force is not enough, the top peak of the staff can not be timely after a reset.
2) Injection problems in production, more production of dust debris, there is no time off in the mold clean-up, leading to the top peak of the staff out of the mold is not smooth; die without timely maintenance, too many impurities and on the ejector lack of lubrication can easily lead to the top of the poor; did not die in the normal production time connected to the cooling water, mold thermal expansion and contraction lead to overheating of the top of the ejector ring true.
