Abstract

Visokotlačno lijevanje je značajan proizvodni postupak koji se primjenjuje u raznim industrijama. Bitna komponenta postupka visokotlačnog lijevanja je kalup. Oblik i karakteristike kalupa utječu na značajke konačnog proizvoda.
U uvodnom dijelu ovog rada dan je kratak pregled povijesnog razvoja postupka lijevanja, a zatim su ukratko pojašnjeni sami postupci lijevanja.
Nakon pokrivenog teorijskog dijela lijevanja, prikazani su interni standardi konstrukcijskih rješenja komponenata kalupa. Za sve bitne komponente objašnjena je njihova uloga u kalupu te u samom procesu lijevanja. Za sve zahtjevnije komponente te za komponente kalupa za koje se smatralo potrebnim, dat je primjer konstrukcijskog rješenja.
U nastavku prikazani su zahtjevi procesa lijevanja, zahtjevi za odljevak te zahtjevi za stroj. U ovom dijelu je također verificiran sam model te izrađeni su ulijevna grana i preljevni džepovi s odzračnicima. Provedeni su svi neophodni proračuni za ovaj korak.
Na kraju ovog rada prikazane su standardne komponente koje su se koristile u projektiranju ovog kalupa. Također, prikazani su problemi koji su se javili u probnom lijevanju te način na koji su otklonjeni.
Sveukupnu nacrtnu dokumentaciju ovog kalupa moguće je pronaći na kraju ovog rada.

Abstract (english)

Die casting is an important manufacturing process used in various industries. An essential component of the high-pressure die casting process is the mold. The shape and characteristics of the mold affect the characteristics of the final product.
In the introductory part of this paper, a brief overview of the historical development of the casting process is given, and then the casting processes themselves are briefly explained.
After the theoretical part of casting has been covered, the internal standards of the structural solutions of the mold components are presented. For all important components, their role in the mold and in the casting process itself is explained. For all the more complex components, and for the mold components for which it was necessary, an example of the design solution is given.
Below are the casting process requirements, casting requirements, and machine requirements. In this part, the model itself was also verified; runner, gate and overflow with vents were made. All necessary calculations for this step were performed.
At the end of this paper, the standard components used in the design of this mold are shown. Also, the problems that occurred in the test casting and the way in which they were eliminated are presented.
The entire documentation of this mold can be found at the end of this thesis.
