Diseño y construcción de un molde para la fabricación en serie para pistones de motor de motocicleta de cilindrada 100cc

Abstract

The manufacture of motorcycle parts in Ecuador has presented difficulties of international dependence by manufacturers, especially those related to two-stroke engines, which hinders a uniform distribution and sufficient dispatch for the country. Therefore, the objective of this research, established the development of the design and construction of a mold for the mass production of motorcycle engine pistons of 100cc displacement. The research methodology implemented had a qualitative-quantitative research approach, applied or action level, experimental design, descriptive type of study, deductive, inductive, and experimental methods. The population and sample consisted of a single representative element, which comprised the 100cc piston, subject to specific dimensions, according to the annexes. In the same methodological section, the designs, calculations, dimensioning, measurements and application of tests, the construction of the mold for piston manufacturing and the aluminum application, tin and copper casting, whose tests took place in the materials laboratory, while the casting was carried out in the foundry workshop of the mechanics faculty at Escuela Superior Politécnica de Chimborazo, were exposed. Through this methodology it was possible to determine the application of reverse engineering using micrography, spectrophotometry and Brinell hardness tests; molding of the two-stroke piston using SolidWorks and Siemens NX 12. Finally, the construction of the mold to manufacture the different elements. In this context, it was possible to conclude the technical feasibility described between the stages of development of the manufacture of the piston, with machines for machining and precision such as milling, pedestal drill, hydraulic press and lathe, for the roughing of the different metal bodies, resulting in an optimal and functional product.
