The Name of the Internal Frame of a Support Structure in Mold Base Industry

Introduction

Mold base is an essential component in the mold making industry. It provides support and stability during the manufacturing process. The internal frame of a mold base plays a crucial role in determining the overall strength and durability of the support structure. In this article, we will explore the name and significance of the internal frame in mold base industry.

The Mold Base Internal Frame

The internal frame of a mold base is commonly referred to as the "backing plate" or "sub-plate". It is a critical element that provides the necessary rigidity and support to the mold components, such as the cavities, cores, and inserts. The main function of the internal frame is to distribute the clamping forces evenly across the mold base, ensuring proper alignment and preventing distortion under high pressure and temperature conditions.

Construction of the Internal Frame

The internal frame is typically made from high-strength steel, such as P20, DIN 1.2738, or S136. These materials offer excellent mechanical properties, such as high tensile strength, hardness, and wear resistance, which are essential for withstanding the demands of the molding process. The internal frame is precisely machined to achieve dimensional accuracy and perfect flatness, ensuring optimal performance and stability of the mold base.

Features of the Internal Frame

The internal frame consists of several key features that enhance its functionality within the mold base structure. These features include:

1. Guide Pin Holes: Guide pin holes are strategically placed in the internal frame to facilitate the alignment and assembly of the mold components. They allow for precise positioning of the cavities, cores, and inserts, ensuring accurate mold closing and part ejection.

2. Ejector Pin Holes: Ejector pin holes are essential for the removal of molded parts from the mold base. They are strategically located in the internal frame to accommodate the ejector pins, which push the parts out of the mold cavities. These holes need to be precisely machined to ensure smooth and consistent part ejection.

3. Water Cooling Channels: Water cooling channels are integrated into the internal frame to regulate the temperature during the molding process. These channels allow for efficient circulation of cooling water, which helps to control the temperature of the mold base and prevent overheating. Proper cooling is crucial in achieving high-quality molded parts and reducing cycle times.

4. Clamping System: The internal frame is designed to incorporate a clamping system that securely holds the mold components in place. The clamping system consists of various elements, such as clamping plates, bolts, and clamping bars, which ensure proper alignment and prevent any movement or shifting during the molding process.

Conclusion

The internal frame of a mold base, also known as the backing plate or sub-plate, is a critical component that provides support and stability to the mold structure. Its name may vary, but its function remains the same. The internal frame is constructed from high-strength steel, machined with precision, and incorporates features such as guide pin holes, ejector pin holes, water cooling channels, and a clamping system. Understanding the importance of the internal frame and its features is crucial in designing and manufacturing a reliable and efficient mold base in the mold making industry.
