Simulación y modelación de una matriz a inyección plástica, para la producción de ASAS de sujeción tipo puente SR 1534 aplicando la tecnología CNC y software de diseño CAD-CAM.

Abstract

The following research focus on the elaboration of one of the main elements in the manufacturing process of plastic products, this element is known as injection mold, is object of the study in which the simulation and modeling of the matrix of the bridge-type holding handles 1534, Through the application of CNC technology. One of the main reasons for the focus on plastics is that they have unique properties, either in isolation or combined with each other. Some of these properties are its elasticity, mechanical malleability, among others. For the production of products based on plastics, injection machines are used, in which varieties of molds are used to obtain different shapes and geometries, in this case, tie rod type, Requires a mold capable of withstanding the internal and external pressure and temperature generated in the injection process, for which it is indispensable a slight calculation of these elements such as: cooling times, internal mold pressure, number of cavities, dimensions of the Mold, plate thickness, etc., Which determine the operations to be taken into account for the machining and subsequent injection process, which is indispensable in obtaining a finished product of quality. The problems of machining in the software simulation are observed in the tool path on the initial material, which were solved before the final machining. Each of the parameters of mold design are governed by international quality standards, the selection of polyamide material plus glass fiber contains better properties for a better grip handle, the correct des-mold calculation ensures the location of ejectors in the critical points. These automated processes and computer aided design packages allow better productivity, reduce costs, and time; In order to present a high standard of quality, precision and functionality, with the help of CNC machines, of the basic workshops of ESPOCH.
