Abstract
A mold includes a die block, a core, two fixing bolts and four screw bolts. The die block includes a top surface, and two side surfaces. The top surface defines a cavity receiving the core. The core includes two opposite outer side surfaces. One side surface defines a first and a second guiding slots extended to the other side surface and communicating with the cavity. One outer side surface defines a third guiding slot aligned with the first guiding slot. The other outer side surface defines a fourth guiding slot aligned with the second guiding slot. One of the fixing bolts inserts into the first and the third guiding slots. The other one of the fixing bolts inserts into the second and fourth guiding slots. The at least two screw bolts respectively engage with the die block until resisting on a corresponding fixing bolt.
