Diseño y construcción de un molde de inyección del arco almohadillado, de protectores auditivos para la empresa Halley Corporación”

Abstract

The object of the present work is satisfy the necessity of the company Halley Corporation, with the end of do the arc pad in series in the same time with certain dimensions, for this reason the author of the work have requirements of the company for elaborate the mold, like the material that will be used for the building, and the plastic that will be used for inject the object that need the company. For this reason, the project was started with the modeling of the arc pad in a specialized software, after that we got the nucleus and cavity of the object to inject. Then with the help of the software we analyze the demoulding angles and the dimensions that need the arc pad. For other part, the calculations were obtained in based of requirements of the company like the material that will be injected, in this case the material is ABS, and the material that will used for the building of the mold Among the calculations that were obtained are the feeding, refrigeration and expulsion systems for asegurate the correct operation of the mold. For finish the project we realized machining of the arc pad with a CNC milling machine, also it was built the different elements that make up the mold. The tests of the construction of the mold were realized with the help of an injecting machine, in this moment we look that the selection of the systems were correct, because the mold had an adequate efficiency in the injection process.
