The mold assembly (100) is provided including a mold plate (20), a mold core (30), an elastic member (40) and an adjusting member (50). The mold plate has a receiving cavity (25) and a receiving aperture (27) defined therein. The mold core is received in the receiving cavity. The elastic member, configured to restore the mold core to its previous position, is disposed between the mold plate and the mold core. The adjusting member is received in the receiving aperture, engaging with the mold core to drive the mold core to move relative to the mold plate.

What is claimed is: 1. A mold assembly, comprising: a mold plate, the mold plate having a receiving cavity and a receiving aperture defined therein; a mold core being received in the receiving cavity, the mold core having an adjusting block arranged thereon; an elastic member being disposed between
What is claimed is: 1. A mold assembly, comprising: a mold plate, the mold plate having a receiving cavity and a receiving aperture defined therein; a mold core being received in the receiving cavity, the mold core having an adjusting block arranged thereon; an elastic member being disposed between the mold plate and the mold core, the elastic member configured to restore the mold core to the mold core's previous position if displaced; and an adjusting member being received in the receiving aperture and comprising a rotatable groove, the adjusting member engaging with the mold core to drive the mold core to move relative to the mold plate during rotation of the groove, the adjusting block engaging into the groove and configured for moving the mold core during rotation of the groove. 2. The mold assembly as claimed in claim 1, wherein the groove is provided with an increasing depth from one end thereof to the other opposite end thereof. 3. The mold assembly as claimed in claim 2, wherein the groove is helically defined extending from one end of the adjusting member to the other end of the adjusting member with an increasing depth. 4. The mold assembly as claimed in claim 2, wherein the mold plate includes a plurality of interior walls, the receiving cavity being formed by the interior walls, the receiving cavity being step-shaped and including an opening, a first receiving cavity and a second receiving cavity connecting the first receiving cavity. 5. The mold assembly as claimed in claim 4, wherein the mold core includes a core portion, a first engaging portion and a second engaging portion, the core portion engaging with the opening, the first engaging portion engaging with the first receiving cavity, the second engaging portion engaging with the second receiving cavity. 6. The mold assembly as claimed in claim 5, wherein the first engaging portion and a second engaging portion cooperatively form a step portion, the elastic member resisting the step portion and the interior wall of the mold plate. 7. The mold assembly as claimed in claim 4, wherein the adjusting block extends downwardly from a bottom of the second engaging portion, and the adjusting member includes a peripheral wall, the groove being defined along the peripheral wall. 8. The mold assembly as claimed in claim 4, wherein the adjusting member also includes an end wall, the end wall abutting on the peripheral wall, the end wall having a slot defined therein. 9. The mold assembly as claimed in claim 1, wherein the mold plate includes an upper wall, a lower wall and four sidewalls, each sidewall abutting on the upper wall and the lower wall, the receiving cavity being defined through the upper wall and the lower wall, the receiving aperture being defined through the two opposite sidewalls, the receiving aperture communicating with the receiving cavity. 10. A mold assembly, comprising: a mold plate, the mold plate having a receiving portion and a receiving aperture defined therein, the receiving portion communicating with the receiving aperture; an elastic member the elastic member positioned between the mold plate and the mold core; a mold core being received in the receiving portion, the mold core having an adjusting block arranged thereon; and an adjusting member, the adjusting member being received in the receiving aperture and defining a rotatable groove, the adjusting member engaging with the mold core and the adjusting block engaging into the groove, the adjusting member being configured such that rotation of the adjusting member about a first longitudinal axis thereof gives rise to a movement of the mold core along a second longitudinal axis, perpendicular to the first longitudinal axis, and movement of the adjusting block being caused by rotation of the groove. 11. The mold assembly as claimed in claim 10, wherein the groove is provided with an increasing depth from one end thereof to the other opposite end thereof. 12. The mold assembly as claimed in claim 11, wherein the groove is helically defined extending from one end of the adjusting member to the other end of the adjusting member with an increasing depth.
