Abstract

Ovaj rad opisuje razvoj kalupa za injekcijsko prešanje kaučukove smjese. Dan je uvid u najvažnije vrste kaučuka, dodatke kaučukovim smjesama i postupke smješavanja. Opisana su preradbena svojstva kaučukovih smjesa, tijek reakcije umrežavanja i vulkanizacije te sustav za injekcijsko prešanje. U praktičnom dijelu rada, koncepcijski je oblikovan kalup za injekcijsko prešanje manžete, a dimenzioniranje kalupa provodi se izradom reološkog i toplinskog proračuna. Temeljem analize rezultata proračuna, donosi se zaključak o parametrima prerade i konstrukciji kalupa za injekcijsko prešanje gumene manžete.
Pri razvoju konstrukcije kalupa za injekcijsko prešanje manžete korišten je programski paket Solidworks2020.

Abstract (english)

This paper describes the development of an injection mould for rubber compounds. An overview of the most important caoutchouc types, additives to rubber compounds, and mixing procedures is given, as well as the description of processing properties, the course of vulcanization and reaction of cross-linking, and the injection moulding system. In the practical part of the paper, the injection mould for cufflinks is designed, and dimensions are defined through rheological and thermodynamic calculations. Based on the analysis of the calculated results, a conclusion is formed about the processing parameters and the construction of the injection mould for rubber cufflinks.
The design of the injection mould for cufflinks was developed by using Solidworks2020 software.
