Diseño y simulación de un molde de 4 cavidades, para inyección de piezas “Lego” de 137.20 x 61 x 37.6 mm y un espesor de 2 mm en absabs

Abstract

The goal of the titling project is the design and simulation of a 4-cavity mold for the injection of lego-type pieces made of acrylonitrile butadiene styrene ABS. Given the growing demand in the plastics industry, the aim is to optimize the manufacturing process, reducing time and costs, as well as guaranteeing the quality and dimensional accuracy of the parts produced. This report is made up of three chapters: in the first, the topic and its justification are introduced; in the second, the relevant theoretical foundations for injection molding are reviewed; and in the third chapter, the methodological framework that will guide the design and simulation of the mold is presented, including the use of specialized software for the optimization of the process. A detailed summary of each of these chapters is provided below. Chapter I: Subject of the degree project • The main topic is presented: Design and simulation of a 4-cavity mold for injection of lego parts of 137.20 x 61 x 37.6 mm and a thickness of 2 mm in ABS. The rationale and importance of the project in relation to the efficient production of plastic parts is clarified. Chapter II: Literature Review or Theoretical Foundations • This chapter discusses key concepts related to injection molding, including balanced flow and potential defects in injection systems. The importance of proper design to optimize production is emphasized. Chapter III: Methodological Framework • The methodology used for the design and simulation of the mold. It includes the use of deductive and experimental approaches, as well as the use of software such as SolidWorks for simulation. Calculations are made on the number of cavities and the appropriate raw material is selected for the manufacture of the mold, in addition to presenting the simulation results on filling times and injection pressures.
