At present, the precision of the ejector pin & sleeve manufactured by our country's mold parts factory can reach the international standard. Today, the core pin manufacturer Yize explains the working principle of the ejector pin & sleeve for you.


Precision ejector pin & sleeve is a kind of plastic mould fittings, that is, there are circular holes or blind holes in the product, and the glue level must be set by a kind of ejection device metal fittings. It consists of two parts, precision pipe jacking and internal needle. The barrel is sleeved on the inner needle. It can move up and down. The inner needle is fixed on the bottom plate of the die, and the barrel is installed on the top needle plate. When the barrel is ejected, the precision barrel moves along with the top needle plate. At this time, the inner needle is fixed on the bottom plate of the die and does not move, so the precision barrel ejects the upper product of the inner needle.



It is necessary to spray rust-proof agent to prevent rust when the ejector pin & sleeve is produced. In the process of using, if the mould is idle for a long time, attention should also be paid to rust-proof. The ejector pin & sleeve after nitriding has the characteristics of wear resistance, durable hot-working die steel, and high temperature resistance above 1200 degrees.


High-quality precision core pin manufacturer Yize provides you with a variety of types of ejector pin & sleeve, high precision, high temperature resistance, wear resistance, high hardness, also can be customized according to the map processing, quality assurance.
