Straight Ejector Pins for industrial applications. DGMF Mold Clamps Co., Ltd offers prompt lead times, competitive pricing, and no minimum order quantity.
1. In plastic molds, separating the product from the mold is also the most commonly used;
2. Carbide ejector pins, such as tungsten steel ejector pins, can be used to pass longer and thinner holes;
3. The ejector pin is also called the lifting top. It is a conical metal round rod with a head that is assembled on a lathe or grinder to support the workpiece and make the workpiece rotate around it, but it is completely different from the ejector pin of the plastic mold accessories;
4. A plastic mold ejector pin can also be used inside the mold, it can play a stabilizing role and is called an insert pin.
The types of plastic mold ejector pins include flat Ejector Pins, dome pins, Shoulder ejector pins, standard straight ejector pins, non-standard straight ejector pins, etc.
The materials of plastic mold ejector pins are SKH51, SKD61, SKD11, 65Mn, etc.
SKH51 straight ejector pin has better toughness than SKD61; The SKD61 thimble can withstand a high temperature of 1600℃, and the surface of the SKD61 Ejector Pin can improve the wear resistance of the Ejector Pin after nitriding.
65Mn ejector pin is of poor quality, brittle, and easy to break. Some plastic molds are no longer assembled and are used with 65Mn ejector pins.
The standard model of Straight Ejector Pins for lathe and grinder:
The standard for a fixed ejector pin is GB/T9204.1-1988 and the standard for a rotary Ejector Pin is JB/T3580-1998.
