Collapsible Injection Pipe Fitting Mould: Design and Functionality A collapsible injection pipe fitting mould is a specialized tool used in plastic injection molding to produce pipe fittings with collapsible or detachable features. These fittings are widely used in plumbing, irrigation, and industrial fluid systems, where ease of assembly, disassembly, or space-saving storage is required. The mould is designed to create precise, high-quality fittings with consistent dimensional accuracy and smooth surface finishes. Key Features of the Mould 1. Collapsible Core Mechanism The mould incorporates a collapsible core system that allows the production of fittings with undercuts or internal threads. This mechanism enables the mould to retract smoothly after injection, ensuring the part can be ejected without damage. The core is typically made of hardened steel to withstand high-pressure injection cycles. 2. High-Precision Cavity Design The mould cavities are CNC-machined to exact specifications, ensuring tight tolerances and uniform wall thickness in the final product. This precision is critical for leak-proof fittings that must meet industry standards. 3. Cooling System Optimization Efficient cooling channels are integrated into the mould to reduce cycle time and prevent warping or shrinkage. Proper cooling ensures consistent part quality and extends the mould’s lifespan. 4. Durable Materials The mould is constructed from high-grade tool steel (such as P20, H13, or stainless steel) to resist wear, corrosion, and high-temperature degradation. Surface treatments like nitriding or chrome plating may be applied for enhanced durability. 5. Ejection System A reliable ejection mechanism, such as hydraulic or pneumatic ejectors, ensures smooth part release without deformation. Some designs include stripper plates or collapsible pins for complex geometries. Applications of Collapsible Pipe Fittings - Plumbing Systems: Quick-connect fittings for easy installation. - Irrigation Systems: Modular fittings for flexible configuration. - Industrial Piping: Detachable joints for maintenance or expansion. Advantages of Using This Mould - High Efficiency: Fast cycle times due to optimized cooling and ejection. - Cost-Effective: Long service life reduces replacement costs. - Versatility: Compatible with various thermoplastics (PP, PVC, PE). In summary, a well-designed collapsible injection pipe fitting mould ensures high productivity, precision, and durability, making it essential for manufacturers of plastic pipe fittings.
