The invention relates to a multipurpose mould with interchangeable moulding plates by means of which three types of test samples can be injected, two meant for mechanical uniaxial traction tests and one meant for mechanical delaminating tests. According to the invention, the mould comprises a fixed pack consisting of a centering ring (1), a fixed clamping plate (2), a nozzle (3), a ring (4), an intermediary plate (5), some centering and guide bushes (6) and two fixed moulding plates (7 and 9) interchangeable for bell samples of the type 1BA and 1B, respectively, which contribute to the injection of two samples (8 and 11), as well as a mobile pack consisting of two mobile moulding plates (10 and 12) interchangeable for bell samples of the type 1BA and 1B, respectively, a mobile moulding plate (14) for the samples needed for the delaminating tests, four centering and guide bushes (15, 19, 23 and 24), some guide bolts (16), a first eliminator (17), a central eliminator (18), some intermediary plates (20 and 25), a thrower holding plate (21), a thrower plate (22), a mobile clamping plate (26) and some interchangeable eliminators (27). Invenţia se referă la o matriţă multifuncţională, cu plăci de formare interschimbabile, cu ajutorul cărora pot fi injectate trei tipuri de epruvete de testare, două destinate testelor mecanice de tracţiune uniaxială, şi una destinată testelor mecanice de delaminare. Matriţa conform invenţiei are în componenţă un pachet fix, format dintr-un inel (1) de centrare, o placă (2) de prindere fixă, o duză (3), un inel (4), o placă (5) intermediară, nişte bucşe (6) de ghidare şi centrare, şi două plăci (7 şi 9) de formare fixe, interschimbabile, pentru epruvete halteră tip 1BA şi, respectiv, 1B, care contribuie la injectarea a două epruvete (8 şi 11), precum şi un pachet mobil, format din două plăci (10 şi 12) de formare mobile, interschimbabile, pentru epruvete halteră tip 1BA şi, respectiv, 1B, o placă (14) de formare mobilă, pentru epruvetele necesare testelor de delaminare, patru bucşe (15, 19, 23 şi 24) de ghidare şi centrare, nişte bolţuri (16) de ghidare, un prim eliminator (17), un eliminator (18) central, nişte plăci (20 şi 25) intermediare, o placă (21) port aruncătoare, o placă (22) aruncătoare, o placă (26) de prindere mobilă şi nişte eliminatoare (27) interschimbabile.
