Plates pre-dimensioning for injection molds by using computational design and inclusion of the parts in BIM methodology

Resumen

This paper presents an algorithm for pre-dimensioning of plates of injection molds based on the measures of the part which will be manufactured. The pre-dimensioning plates are: the cavity plate, the core plate and the support plate. These plates will be pre-dimensioned according to the pressure loads generated in each case, derived from the specific requirements needed for the injection and manufacture of each plastic part. Additionally, the used equations will be introduced into computational design software linking each variable with his relative parameter in order to generalize the process of injection mold designing for simple plastic parts. After calculus process and the pre-dimensioning of the plates the final geometry will be introduced into BIM methodology using specifics BIM software in order to measure the quantities of material required, to collect dimensions and number of parts needed in an automatic way to get other interesting attributes like budget control. The implementation of BIM methodology in injection molds industry to project development gives engineering field many new possibilities of co-working between companies, making easier the communication of their design specialists optimizing the process of creation of new injection molds. This methodology will contribute to save resources improving the quality of the projects final results
