The difference between mold frame and mold kernel

The difference between mold frame and mold kernel

With the continuous development of industrial manufacturing technology, various new materials, processes and equipment continue to emerge, which has brought great changes to all walks of life. In the mold industry, the mold frame and the mold kernel are two crucial parts, and their difference and use directly affect the quality and production efficiency of the product. This paper will focus on the difference between mold frame and mold kernel, in order to provide valuable reference for readers.

First, the definition and function of mold frame and mold kernel

1. Mold frame

The mold frame, also known as the mold frame, is the main part of the mold, which plays the role of support and positioning. The mold frame is usually made of steel, aluminum alloy and other metal materials, and its structural form and size are designed according to the shape and size of the product. The mold frame is installed with various forms, cooling water channels, guide posts, guide sleeves and other parts, which together constitute the working system of the mold. The quality of the mold frame directly affects the service life of the mold and the quality of the product.

2. Mold kernel

Die kernel, also known as the mold core, is the part of the mold directly in contact with the product, which plays the role of forming and transferring pressure. The mold is usually made of hard alloy, high-speed steel, ceramics and other wear-resistant materials, and its shape and size are designed according to the shape and size of the product. The mold is provided with cooling water channel, exhaust hole and other structures to ensure the quality and efficiency of the product.

Second, the difference between mold frame and mold kernel

1. Different materials

The mold frame is usually made of metal materials, such as steel, aluminum alloy, etc., to withstand large forces and deformation; The mold is made of wear-resistant materials, such as cemented carbide, high-speed steel, ceramics, etc., to ensure the molding quality and service life of the product.

2. Different structures

The mold frame mainly plays the role of support and positioning, and its structure is relatively simple; The mold needs to withstand greater pressure, and its structure is more complex, with cooling water channels, exhaust holes and other structures.

3. Different functions

The mold frame mainly plays the role of support and positioning to ensure the stability and accuracy of the mold; The mold kernel is directly involved in the molding process of the product, affecting the quality and efficiency of the product.

4. The replacement frequency is different

The service life of the mold frame is long, generally do not need to be replaced frequently; Due to the greater pressure and wear of the mold, it is necessary to check and replace it regularly to ensure the quality of the product and the service life of the mold.

Third, the selection and application of mold frame and mold kernel

1. Selection of mold frame

The choice of mold frame should be determined according to the shape, size and production volume of the product. Generally speaking, the mold frame with good rigidity and high precision can be selected for mass production; The mold frame with simple structure and low cost can be selected for small batch production. In addition, it is also necessary to consider the size, shape, material and other factors of the mold frame to meet the requirements of the use of the product.

2. Choice of mold kernel

The choice of mold should be determined according to the material, shape and size of the product. Generally speaking, cemented carbide die is suitable for high temperature, high pressure, high friction conditions forming; The high speed steel die is suitable for forming under the conditions of medium temperature, medium pressure and medium friction. Ceramic molds are suitable for forming under low temperature, low pressure and low friction conditions. In addition, it is necessary to consider the size, shape, material and other factors of the mold to meet the requirements of the product.

3. Mold frame and mold kernel

The combination of mold and mold has an important effect on the quality of the product and the service life of the mold. In general, the mold frame should be selected with good rigidity and high precision, and the mold should be selected with good wear resistance and high hardness. In addition, it is also necessary to pay attention to the coefficient of thermal expansion of the mold and the mold, processing technology and other factors to ensure the stability and accuracy of the mold.

Iv. Conclusion

In short, the mold and the mold have a pivotal position in the mold, and their difference and use directly affect the quality and production efficiency of the product. Therefore, in the mold design and manufacturing process, the choice of mold and mold should be fully considered to ensure the stability and accuracy of the mold, and improve the quality and production efficiency of the product. With the continuous development of industrial manufacturing technology, it is believed that the materials, processes and structures of mold frames and molds will continue to be optimized, bringing more possibilities to the mold industry.
