Abstract

Tiparul extensibil pentru fabricarea pieselor din ghips contine cel putin doi pereti asamblati cu ajutorul a cel putin doua elemente deformabile incompresibile dispuse, respectiv între doua margini laterale paralele ale peretilor, astfel încît sa asigure etanseitatea acestor pereti, fiecare din elemente luînd spre interiorul tiparului la scoaterea din tipar sub efectul presiunii, un profil determinat dinainte corespunzator celui care trebuie dat unei suprafete a piesei turnate si care se retrage în afara contactului cu piesa turnata la scoaterea din tipar dupa relaxarea presiunii, în timp ce se îndeparteaza unul de altul peretii între care este asezat fara a înceta sa asigure etanseitatea între margini, a suprafetei de baza pe care se sprijina peretii si elementele compresibile si un orificiu de curgere amenajat între pereti.
