What are mold ejector pin marks?
The [ejector pin] of the die-casting mold is an important component. The ejector pin position is usually designed on the back of the finished product or in an inconspicuous position.
Its functions and functions mainly include the following points:
1. Mold opening and closing control:
The ejector pin plays a key role in the opening and closing process of the mold. When the mold is closed, the ejector pin will be pressed into the mold to ensure that the various parts inside the mold can fit tightly.
The required die-casting space is formed. When the mold is opened, the ejector pin will be pulled back, so that the mold can be separated smoothly and the finished die-casting product can be easily taken out.
2. Eject the die-cast product:
During the die-casting process, the ejector pin mainly assists in the ejection of the finished product. When the die-cast product cools and solidifies, the function of the ejector pin is to push (push) the finished product out of the mold to facilitate demolding.
This helps improve production efficiency and ensure the quality of die-cast finished products.
3. Cooling system channel:
In some die-casting molds, the ejector pin may also be designed as part of the cooling channel, which can effectively cool the inside of the mold and improve the stability of the die-casting mold.
4. Positioning function:
The ejector pin also plays a positioning role in the mold; during the mold closing process, the precise positioning of the ejector pin ensures the accurate alignment of the various parts inside the mold, thereby ensuring the accuracy of the die-casting finished product.
The ejector pin in the die-casting mold is a multi-functional component that not only ensures the correct opening and closing of the mold, but also helps eject the finished product. We will obtain bidirectional agreement with the customer through mold flow analysis to arrange the appropriate ejection position.
