What should you do if there is a stuck phenomenon during the operation of the mold? For the solution in this regard, you can check the suggestions given by the relevant professionals:
1 Inspect the ejector pin and the thimble hole for signs of burns
2 Is the ejection of the injection molding machine flat?
3 Whether the thimble hole is crooked
4 The concentricity between the board and the board is not done well
5 Caused by the poor verticality of the thimble
6 The thimble holes should be smooth, and the small thimble mold base should not be too large.
7 Check whether the lower middle torsion (the guidepost on the thimble board) is functioning. If the processing is biased or the gap is too large, it is very likely that the thimble will burn.
8 Check carefully, do not install the spring first (if there is no spring, you can try it directly), install the male mold, and try the ejection system on the ground. If it is all smooth, look at the spring. When it is confirmed that there is no problem, look at the machine. mandrel. There are also new molds that must be maintained. In the trial production stage, at least once every half a day, the thimble oil is guaranteed to prevent it from being stuck during running-in.
9 Make a bigger hole in the back of the mold core and apply thimble oil
10 Also pay attention to whether the mold temperature is high.
