    Diseño y construcción de un molde de inyección de gafas de seguridad de la empresa Arakiprod Cia. Ltda
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2019) Campaña Cortés, Fabricio Germán; Carrillo Rosero, Carlos Mauricio
    The execution is carried out with the investigation of legal regulations that authorize the design and construction of eye protectors and that is legally permitted in Ecuador, this being the official registry RTE INEN 216, which cites the standard EN 166: 2001 as reference for the design and construction of eye protectors. In accordance with the beneficiary company, a design for "glasses with lateral protection" is established and focuses on optimizing conventional designs under the concept of less, moreover, providing greater protection of the eye area proposed by the standard mentioned with a product of three elements that are assembled by adjustment and without metallic pins. The final geometry was obtained after several designs that were captured in prototypes by means of molten deposition molding (3D printing) and served as a guide to visualize constructive details. Once the 3D geometry was established, the CAD design of the matrix for injection molding was carried out, where the parameters of the injection machines were used for the design of two injection molds, injection pressure parameters, closing force, and injection capacity define the geometry of the mold and number of cavities. Each element of the injection molds was built, with a manufacturing process by chip removal that allows obtaining each mechanized element. To then be assembled piece by piece and then mounted on the injection machine, where injection tests were carried out until the desired product was obtained.

    Diseño y construcción de un molde de inyección para el soporte unión entre el casco y la carcasa de la orejera para la empresa Halley Corporación
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Mecánica, 2018) Fonseca Muncha, Antonio Fernando; Carrillo Rosero, Carlos Mauricio
    The present work has as objective to satisfy the necessity of the clients of the Halley Corporation Company, since this one comes to be sponsor of this project with the purpose of manufacturing a mold that counts on the geometric requirements and of design imposed by the same one to produce this type of supports which have materials provided by the company, which have the necessary characteristics for its elaboration. The project started from an idea of making the support in the form of a semidiadema which resembles what is required and necessary by the company, for which a design was presented by the author of this same work that had several modifications based on what is required. As a second point, the same calculations that were made based on the materials that the company had for this project, such as ABS as material for injection and other materials for the manufacture of the mold, were taken into consideration. Generating estimated values in terms of cooling systems, power and machining which would allow the mold to fulfill its function and have no problem. Once established these values and considering the availability of the machinery that owned the company proceeded to perform both manual and CNC machining of most parts of the mold and then perform the assembly of these and proceed to perform the necessary tests in the injecting machine itself of the company, demonstrating that what was accomplished was successful based on decision making and selection of both design and geometric parameters.
