8 Tips to troubleshoot injection mold failures

Therefore, the moving formwork must be made of high-quality steel, and it must have sufficient thickness. Low-strength steel plates such as A3 must not be used. When necessary, support columns or blocks should be set under the moving formwork to reduce the thickness of the formwork and improve the carrying capacity.

5. The jack is bent, broken or missing

The quality of the self-made ejector is good, which means that the processing cost is too high. Nowadays, standard parts are usually used, and the quality is average. If the gap between the ejector pin and the hole is too large, material leakage will occur, but if the clearance is too small, the ejector pin will swell due to the rise of the mold temperature during the injection. What is more dangerous is that sometimes the ejector pin is ejected at a normal distance and breaks. As a result, the exposed ejector pin cannot be reset when the next mold is closed, and the concave mold is damaged.

In order to solve this problem, the ejector rod was reground, and a fitting section of 10-15 mm was retained at the front end of the ejector rod, and the middle part was milled 0.2 mm smaller. After the assembly of all ejectors, the fit clearance must be strictly checked, generally within 0.05 ~ 0.08 mm, to ensure that the entire ejection mechanism can move forward and backward freely.
