Disclosed is a mold, comprising a fixed half, a moving half, a push-out structure and a return protection system. The moving half has a pressing part. The push-out structure is installed on the fixed half. The push-out structure comprises a push-out element and a push-out plate. The return protection system comprises a return pin and an elastic element, installed between the return pin and the push-out element. The pressing part can press against the return pin. With the elastic element, the return pin can drive the push-out structure. It can prevent the moving half to interfere the push-out element and to impact the fixed half. Accordingly, the lifetimes of the push-out structure and the parting planes of the mold can be extended to reduce the maintenance cost. Noise caused by closing mold with high speed can be prevented to raise the stability and the productivity of manufacture.
