At least two connecting elements each have its one end positioned in one of the at least two cavity plates while the other end passing through the other cavity plate for movably connecting the at least two cavity plates with each other. At least one elastic element is compressibly disposed between and against the cavity plates in such a manner such that the at least two cavity plates are capable of contacting with each other or separating from each other. The second mold is engaged with the first mold for compelling one of the at least two cavity plates to move toward the other cavity plate so that the at least two cavity plates are in contact with each other.
