Abstract

PURPOSE: To prevent the camber of a liner and eliminate the formation of flash by providing voids between the liner and a main mold.
CONSTITUTION: A hole 6 holding a fixing pin 7 is provided near the side face of a main mold on the back face of the central part of a liner 2 shorter than the main mold 1 in the longitudinal direction of the liner 2, and a through-hole 5 is provided in the main mold 1 as well in the place similar to the liner mold 2 pin hole 6. The fixing pin 7 is installed therein to provide the basic part for joining of the main mold 1 and the liner mold 2. Similarly on the opposite side a key way 8 is provided to the main mold and a key 10 is installed. On the other hand, a key way 9 sliding the key 10 is provided to the liner 2. When the liner mold 2 expands or contract, the key is slided in the central part to assure the swing to the right and left. With the basic part and key 10 as a center, the liner 2 expands and contracts to the right and left, and in order to prevent these, voids 4a, 4b are provided between the liner 2 and the main mold 1. On the other hand, with respect to the forward and backard expansion and contraction, the liner is moved only in one direction from the basic part for joining, thus the main mold of the three side faces excluding the side face of the main mold 1 and the bottom face is formed.
