Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ejector rod measuring tools, in particular to an ejector rod measuring structure used in a mold ejection mechanism. Background Art
[0002] The ejector block accounts for a large part of the ejector mechanism in the mold. In a general mold, there are about 60 ejector blocks, and some even more. At present, a feeler gauge, also known as a gap piece, is often used to compare the height of the ejector block parting surface with the main insert to determine how much margin there is under the ejector pin of a certain ejector block.
[0003] Although this method can adjust the length of the ejector, it takes a long time and the result is not very good. This is because there are many uncertain factors, including whether the ejector block is properly matched, whether the burrs on the parting surface are smooth, and whether everyone's method of comparing the gap is consistent. This means that there is no accurate identification of the accuracy of the measured data, and it often takes a long time to adjust the ejector, and sometimes it is not adjusted properly.
[0004] Since the end face of the ejector pin is lower than the profile face and the ejector block groove is also very small, a depth gauge cannot fit in it. Although a depth gauge with a small head can be used for measurement, the value measured each time is not very accurate and there will be errors due to the small end face of the depth gauge.
