1. Guide Pillar Damage Guide pillars play a crucial role in guiding the mold to ensure that the forming surfaces of the core and cavity do not collide. They should not be used as load-bearing or positioning components. Significant lateral…
Injection molds comprise six major systems, and among them, the guiding system ensures the accurate alignment of the moving and fixed molds during molding. Guide components are crucial in molds, typically consisting of four sets of guide pillars and guide…
The inability of the injection molding die spring to rebound may be due to the following reasons: To address these issues, a thorough review of design parameters is necessary. Ensure the selection of a spring type suitable for the intended…
These criteria are designed to ensure that the chosen materials for mold components meet the stringent requirements of the molding process and production, facilitating an efficient and effective manufacturing process.
Manufacturing mold steels are diverse, adhering to standards from the United States, Germany, Japan, and national standards. They can be classified based on the intended use of the mold into cold work mold steel, hot work mold steel, plastic mold…
Mold springs are commonly made of chromium alloy steel, known for its high temperature resistance, high rigidity, and long lifespan. Here are the characteristics of four major mold spring materials:
Formula for Calculating Mold Spring Pressure When designing and selecting mold springs, the most fundamental criterion is whether the spring force can ensure smooth production of the mold. The most widely used and critical components in molds are the ejector…
Plastic molds, abbreviated as molds, are a type of composite mold used for compression molding, extrusion molding, injection molding, blow molding, and low-foam molding. The coordinated variation of the mold’s convex and concave molds, along with auxiliary forming systems, can…
Mold springs are widely used mechanical components in molds. They are typically not used independently but serve as auxiliary power for moving components such as ejector plates or core pins. The categories of mold springs can be distinguished by their…
Introduction: Stamping dies play a crucial role in metal forming processes, and determining a safe stamping frequency is vital for maintaining tool longevity and ensuring operational safety. The optimal frequency varies based on several factors, and finding the right balance…
