The mold tube thimble can not return to the designated position, the left and right sides have what is going on!
Your question is a bit general. It may be that the head on the top of the cylinder is larger than the actual one.
When is the top, our can too force the Boss into the top. Enhanced polishing and increased ejector ejector pin. I hope I can help you.
The situation you are talking about may be the following questions,1, the thimble plate sink too deep (see what you asked, should be checked, can be ruled out)2, our tube and the mold with smooth, tight when it is heated, so that the ejector plate back in place, but this problem will lead to other thimble will back in place, and only in the back needle short will appear this situation, or to be back pressure needle. You can check this again. If only the cylinder is higher, you should see whether the front of the thimble plate is too small or not. When the tube is out of order, the tube hangs in front of it. If it's good, it won't be possible unless the cylinder is of the wrong height. Or the barrel is stretched. Ha-ha3, your cylinder fits into the cage, and the rear side of the cylinder is too small to support.4, you said "just like back in place, flash out", this sentence, you did not go to the measurement of product is not short column two mm, the two began to die well, is behind. There is also a case of ejector pin back, making our cylinder the steps below our needle tube, that will also appear flash like this to confirm the ejector pin plate bolt can lock the screw end, and big enough, if the needle is large enough, is to end lock screw. If the needle is relatively small and long, on the way to do a Tozzi gatto, syringes and needles. If the needle is broken, you want to see the length, right? Is there too much preload?
