The mold base is the foundation and core component of the mold. Its structure and function have a decisive impact on the performance and production efficiency of the mold. Below, the editor of Xindali Mold Base will introduce the structure and function of the mold base in detail.
1. Structure of the mold base
1. Panel: The panel is the main load-bearing part of the mold base. It carries components such as the punch mold, the concave mold, and the blank holder. Panels are generally made from thick steel plates and are heat treated to improve strength and wear resistance;
2. A-plate (front template): A-plate is the front side panel of the mold base. It cooperates with the punch, blank holder, etc. to control the inflow of metal materials. A-plate is also generally made of thick steel plate and heat-treated to improve strength and wear resistance;
3. B plate (rear template): B plate is the rear side panel of the mold base. It cooperates with the concave mold, ejector pin, etc. to control the forming of metal materials. B plate is also generally made of thick steel plate and heat treated to improve strength and wear resistance;
4. C plate (square iron): C plate is the middle support of the mold base. It cooperates with the panel, A plate, B plate, etc. to control the opening, closing and movement of the mold. C plate is generally made of cast iron or alloy steel;
5. Bottom plate: The bottom plate is the bottom support of the mold base. It carries the weight and impact load of the mold base. The bottom plate is generally made of thick steel plate or cast iron;
6. Ejector panel and ejector bottom plate: The ejector panel and ejector bottom plate are components used to install the ejector pin. They are generally made of thick steel plates or cast iron;
7. Sleeve cylinder, guide post, back pin: Sleeve cylinder, guide post, back pin, etc. are guide components. They ensure the precise alignment between the punch and the concave die, reduce mold wear, and improve the mold accuracy;
8. Support head: The support head is a component used to adjust the mold gap. It is generally made of wear-resistant materials and can be disassembled and replaced;
9. Limiting nail: The limiting nail is a component used to limit the opening and closing position of the mold. It can prevent the mold from being damaged due to excessive opening and closing.
2. Function of mold base
1. Positioning function: As the skeleton of the mold, the mold base must accurately determine the position between the punch and the die to ensure stamping accuracy. At the same time, the mold base also has to bear the weight and impact load of components such as the punch and concave mold;
2. Guide function: The guide elements on the mold base (such as cylinders, guide posts, back pins, etc.) should guide the movement between the punch and the die to ensure the smooth progress of the stamping process;
3. Support function: The mold base must provide support for components such as the punch and concave molds to maintain the overall rigidity and stability of the mold;
4. Adjustment function: The support head on the mold base can adjust the mold gap to adapt to the stamping requirements of different materials. At the same time, the limiting nail can limit the opening and closing position of the mold to prevent damage caused by excessive opening and closing of the mold;
5. Connection function: Various fasteners (such as screws, pins, etc.) on the mold base can connect the punch mold, concave mold, blank holder and other components together to form a complete mold.
In short, the structure and function of the mold base are complementary to each other. Only by fully understanding and mastering the structure and function of the mold base can we better design and manufacture high-quality, high-performance molds.
