Automatización y puesta en marcha de una máquina inyectora de plástico para la Empresa matricería y producción EDBOR

Abstract

The purpose of the present research is based on the implementation of an automated system of a plastic-injection molding machine for “Matricería y Producción EDBOR Company” in order to reduce time in the development of parts through an established injection volume. To determine the mechanical, electrical and electro-hydraulic elements that are required in the automation of the injection machine developed the designs for the mechanical system of the injection machine; with the aim of making the fittings of the cylinders and other devices for the proper operation. The machine contains the following elements: two pneumatic cylinders standardized, heating resistance bands, temperature controller, moulds, PLC, electro-valves and filter regulator and lubricator. The static study was made by using the software SOLID WORK which allowed verifying that the mechanical structure does not need any other modifications to support the additional charges that will be included to automate the machine. After making connections, fittings and obtaining sealing in the pneumatic system, it makes the PLC programing which will be useful for the machine works properly. Finally functional test are performed by coordinating the cycles of the advance and return for each cylinder and times operating for each work cycle. When automatic plastic-injection molding machine, it allows to inject polymer of polypropylene PP with a maximum injection volume of 35 cm3 , depending on the mould used. The automation process reduces the production time of the parts, besides the uniformity in the production of each batch obtained.
