Introduction
The construction of a Longji Standard Framework in the mold base industry requires careful attention to detail and a thorough understanding of the differences between heaven and earth. This article will discuss the key points to consider when differentiating between these two elements in the construction process.Design Process
In the design process of a Longji Standard Framework, it is crucial to distinguish between the heaven and earth components. Heaven refers to the upper part of the mold base, including the cavity and core, while earth refers to the lower part, including the sprue bushing and support pillars.
When designing the heaven component, it is important to focus on the shape, size, and surface finish. The cavity and core should be precisely designed to meet the requirements of the final product. This includes considering factors such as material shrinkage, parting line location, and draft angles. The selection of suitable materials for the heaven component is also critical, as it determines the durability and performance of the mold.
On the other hand, the design of the earth component should prioritize stability and strength. The sprue bushing should be designed to ensure smooth flow of molten material into the cavity. The support pillars should be robust enough to withstand the pressure and weight exerted on the mold during the injection molding process.
Material Selection
The selection of materials for both heaven and earth components is a crucial step in the construction process. For the heaven component, materials such as high-speed tool steel or stainless steel are commonly used due to their high strength and wear resistance. These materials can withstand high temperatures and repetitive cycles without deformation.
For the earth component, materials such as hardened steel or pre-hardened steel are preferred for their durability and stability. These materials have superior hardness and can withstand the pressure exerted on the mold during injection molding processes.
Manufacturing Process
The manufacturing process of the Longji Standard Framework should adhere to strict guidelines to ensure the differentiation of heaven and earth components. Precision machining techniques should be used to create the desired shape and dimensions for both components.
The heaven component may require additional processes such as EDM (electrical discharge machining) or polishing to achieve the desired surface finish. This is crucial to ensure the final product meets the required quality standards.
For the earth component, processes such as milling, grinding, and heat treatment are often employed to achieve the necessary dimensional accuracy and strength.
Quality Control
Quality control is of utmost importance in the construction of a Longji Standard Framework. Each component, whether heaven or earth, should undergo rigorous inspection to ensure it meets the required specifications. This includes dimensional accuracy, hardness, surface finish, and material integrity.
The use of advanced measuring equipment, such as CMM (Coordinate Measuring Machine), is highly recommended to accurately assess the quality of the components.
Conclusion
In conclusion, the construction of a Longji Standard Framework in the mold base industry requires a clear differentiation between heaven and earth components. By focusing on the design process, material selection, manufacturing process, and quality control, manufacturers can ensure the creation of a high-quality and reliable mold base.
