Injection mold structure problems

This problem is written to tell you, you will not understand too much. The front plate of the mold is placed on the front fixed plate of the injection molding machine. Because the injection molding machine's front fixed plate is a principle of injection molding, the mold with screws attached to the injection molding machine's front fixed plate. There is an injection port in the shape of a needle on the fixed plate of the injection molding machine, which is aligned with the injection port of the mold. This is the front fixing plate. The back is the same. Use the back fixing plate of the injection molding machine to fix the back mold of the mold with screws. This problem: again, those two plates than the mold before and after the template and not just a little bit bigger, is a lot bigger, put in the mold structure chart size ratio are wrong. Because the size of the mold is not the same, an injection molding machine is generally applicable to that size to that size of the mold. The one you see may be a small size. But the injection molding machine can put this mold to produce products. You'd better go and see for yourself. Once you have seen it, these questions of yours will not be a problem.
