This project involves the design and 3D modeling of a plastic injection mold for a lever valve cartridge shell in SolidWorks software. In the design process, all mold components, including plates, gate system, ejector mechanism, and standard parts, have been precisely designed and assembled in accordance with engineering principles and manufacturability.
The goal of this project was to achieve a mold with stable performance, high quality of the manufactured part, and increased productivity in the production process. In the design of this mold, factors such as ease of assembly and maintenance, reduced production cycle time, strength of parts, and the possibility of mass production have been considered.
In this project, the plastic injection mold process for the lever valve cartridge shell was simulated and evaluated using Autodesk Moldflow Insight software to accurately examine the performance of the mold before manufacturing. The analyses included examining the mold cavity filling pattern, injection time, temperature distribution, injection pressure, gate and cooling system performance, the possibility of weld lines, air entrapment, and shrinkage of the part. Based on the results obtained, the position of the gates and melt flow paths were optimized to fill all cavities uniformly and increase the quality of parts in mass production. In addition to reducing trial and error in the mold construction stage, this simulation improved the production cycle, reduced waste, increased process stability, and achieved parts with the desired dimensional accuracy and surface quality.
