For example, a chamfer can be made at the corner of the upper mold 10 as the upper mark 114, and the same or similar chamfer can be made at the corresponding corner of the lower mold 20 as the lower mark 216. The upper mark 114 and the lower mark 216 correspond to each other in position when the molds are closed. The upper mark 114 and the lower mark 216 are used to identify the correct installation position when the upper mold 10 and the lower mold 20 are assembled. The visualized upper mark 114 and the lower mark 216 enable the operator to quickly identify the assembly direction and position of the jig, saving the operator's installation time and helping to improve the efficiency of jig assembly.
