Function Of Ejector Pin
A ejector pin is a tool used in industries such as injection molding or die casting whose main function is to push the finished product or part out of the mold. ejector pins are usually made of high-strength steel with wear and corrosion resistance.
1. Ejecting the finished product: One of the main functions of the ejector pin is to ejecting the finished product from the mold. During injection molding, when the plastic material fills the mold and cools and solidifies, the ejector pin pushes the finished product out of the mold through upward movement for further processing or packaging. The design and use of the ejector pin must ensure that the finished product ejects smoothly and accurately from the mold to avoid damage or deformation.
2. Remove residue: In addition to ejecting the finished product, the ejector pin can also be used to remove residue from the mold. During injection molding or die casting, plastic or metal materials may remain in the mold, and if not removed in time, it will affect the next production. By ejecting the residue, the ejector pin ensures the internal cleaning of the mold, improving production efficiency and product quality.
3. Separate mold: ejector pin can also be used to separate mold. In the injection molding process, the mold is usually composed of two or more parts, through the role of the ejector pin, the various parts of the mold can be separated, so that the finished product can be taken out smoothly. The design and installation position of the ejector pin need to consider the structure and shape of the mold to ensure a smooth and reliable separation process of the mold.
4. Control product size: ejector pin can also be used to control the size of the product. By adjusting the length or position of the ejector pin, you can affect the shape and size of the finished product. The design and use of the ejector pin need to be adjusted according to the requirements of the product to ensure the accuracy and consistency of the finished product.
5. Improve production efficiency: The correct use of ejector pin can improve production efficiency. The design and installation of the ejector pin needs to consider the speed and stability of the production process to ensure the ejection speed and quality of the finished product. Reasonable selection of the material and size of the ejector pin, as well as regular maintenance and maintenance, can extend the service life of the ejector pin and reduce failures and downtime in production.
Type Of Ejector Pin
ejector pin is a tool widely used in injection molding, die casting, mold manufacturing and other industries. According to different application requirements and working environment, there are many types and specifications of ejector pins. The following details several common ejector pin types and their use in different application areas.
1. Straight ejector pin: The straight ejector pin is one of the most common types of ejector pin. It has a straight rod-like design, with one end attached to the mold and the other end used for ejecting the finished product. Straight ejector pins are suitable for injection molding and die casting industries, and are often used to push out small or medium-sized finished products. The length and diameter of the straight ejector pin can be adjusted according to the product size and mold structure.
2. Oblique ejector pin: The oblique ejector pin is a ejector pin with a inclined Angle. Its top is angled to the surface of the mold, making it easier to push the finished product out. Oblique ejector pins are suitable for injection molding and die casting, especially for ejecting large sizes or complex shapes. The tilt Angle and length of the inclined ejector pin need to be adjusted according to the requirements of the product and the mold.
3. Spring ejector pin: Spring ejector pin is a kind of elastic ejector pin. It usually consists of a spring and a ejector pin rod, which can automatically spring back after ejecting the finished product. The spring ejector pin is suitable for high-speed production lines or scenarios that require frequent ejection of the finished product. It can improve production efficiency and reduce the labor intensity of operators. The elasticity and length of the spring ejector pin need to be selected according to the specific application.
4. Pneumatic ejector pin: The pneumatic ejector pin is a ejector pin that controls the ejection action through air pressure. It usually consists of a cylinder and a ejector pin rod, through the rise and fall of air pressure to achieve the ejection of the finished product. Pneumatic ejector pins are suitable for high-speed production lines or scenarios where ejection forces need to be precisely controlled. It can provide a more stable ejection force, and can adjust the air pressure to achieve the ejection needs of different products.
In addition to the above types of ejector pins, there are some special ejector pins, such as rotary ejector pins, hydraulic ejector pins, etc., which have special functions and advantages in specific application fields.
In practical applications, the choice of ejector pin needs to consider a number of factors, such as product size, mold structure, ejecting force requirements. Reasonable selection and use of ejector pin can improve production efficiency, reduce costs, and ensure product quality and consistency. Therefore, it is very important to understand the different types of ejector pins and their application scenarios in order to make the right choice in practical applications.

The Application Notes Of Ejector Pin
As an important part of the mold, the correct application and use of the ejector pin is crucial to product quality and production efficiency. Here are some considerations for ejector pin application:
1. Choose the right ejector pin: When choosing the ejector pin, choose the right ejector pin type and specification according to the specific product requirements and mold structure. Different products may require different types and sizes of ejector pins, such as straight ejector pins, oblique ejector pins, rotary ejector pins, etc. At the same time, the material and wear resistance of the ejector pin should also be considered to ensure that it can work stably for a long time.
2. Ensure that the ejection force is appropriate: the ejection force of the ejector pin should match the product requirements. If the ejector force is too large, it may cause deformation or damage to the product; If the ejector force is too small, it may not be able to ejector the product completely. According to the material and size of the product, choose the appropriate ejector pin length and diameter, and the appropriate spring or air pressure to adjust the ejection force.
3. Correct installation and adjustment of the ejector pin: The installation and adjustment of the ejector pin should pay attention to accuracy and stability. Ensure that the ejector pin is properly installed on the mold and that the finished product can be ejected smoothly. During the installation and adjustment process, pay attention to the position and Angle of the ejector pin to ensure that the ejecting product meets the requirements.
4. Regular maintenance and replacement of the ejector pin: The ejector pin may be worn or damaged after prolonged use, so it needs regular maintenance and replacement. Check the status of the ejector pin regularly, such as the bend of the rod, the elasticity of the spring, etc., to ensure that it works properly. Replace the worn or damaged ejector pin in time to avoid affecting product quality and production efficiency.
5. Pay attention to the cleaning and lubrication of the ejector pin: the ejector pin may be polluted by dust, oil, etc., during use, affecting its normal work. Therefore, the ejector pin needs to be cleaned regularly and properly lubricated. Choose suitable cleaners and lubricants to avoid corrosion or damage to the ejector pin material.
6. Record and manage the ejector pin well: For the ejector pin used in mass production, it is recommended to establish a sound ejector pin record and management system. Record ejector pin usage, maintenance and replacement records to track and manage ejector pin status and life in a timely manner.
