In the mold, the most common mold parts include flat ejector pin, core pins and sleeves, etc. Flat ejector pin is used more in plastic mold. Flat ejector pin is more difficult to grind than mold parts core pins and sleeves, so it is generally more expensive. Their main materials include SKD61、SKD11、SKD51、SKH61、AKH51、SKH11 and so on. Flat ejector pin mainly used in the ejection of rod part of plastic products and the elongated glue. When round thimble can not drop, we choose to use flat ejector pin.
The machining process of mold parts core pins and sleeves:
From design to machining, the diameter of core pins and sleeves should be first to determine. X, Y position can output a text file. Moreover, you can also add some other dimensions.
The purpose of mold parts core pins and sleeves:
1.In the plastic mold, separate the product from the mold, which is the most commonly used.
2.Carbide core pins and sleeves, such as tungsten carbide core pins and sleeves, can be used to pass the long and thin holes.
3.core pins and sleeves is assembled on a lathe or grinding machine, which is used to support the workpiece and the workpiece turning around its head conical metal rods.
Yize as one of leaders of core pins and sleeves manufacturer in China, we regard providing high-quality core pins and sleeves to customers as our mission.
