Diseño de un molde para fabricación de suelas FABYA tamaño 37 de poliuretano, utilizando ingeniería CAD CAM CAE.

Abstract

This research was carried to contribute in the sole manufacturing, to motivate the productive-matrix change, to replace the sole importation and to leave a model of mold manufacturing in the laboratory of mechanics engineering school because it is implementing materials at the moment. Three kinds of molding were studied for polyurethane such as: injection, compression and transference. From this information, QFD (Quality Function Deployment) matrix was developed and the mold was designed. First at all, the mold was shaped by means of CAD (Computer Aided Design), sole and mold were validated and manufacturing by CAE (Computer Aided Engineering) and CAM (Computer Aided Manufacturing) with thermal simulation, resistance and deflection. Thicknesses, minimum measurements and a mold weight of 21.9 kg were gotten. A mold carrier which opens and closes the mold was made. From QFD matrix, production time reduction and lightness with a low consumption of energy were taken into account. All the mechanical elements were calculated manually and verified by CAE validation. A semi-automatic system open and closes this mold using an pneumatic cylinder with 250mm which lifts weights up to 35kg (mold). Instructions about construction and assembly of the mold and mold carrier were showed. In addition, the estimated cost of 2449 USD for mold and 1332 for mold carrier were calculated in order to achieve the job applied by the sponsor enterprise shop store CAVE.
