Stop switch

  • Detailed introduction

Name of product: Stop top rod

Material: SKD61

Hardness: internal vacuum HRC52°±2°

Nitrided surface HV900°-1100°

The non-rotating top mandrel is mainly used in the case of large molds where some of the molding top blocks are small and only single bars are used. If the molded top piece connected by a single rod is not designed to stop the flat tape, once the loosening or breaking of the bottom fixing screw in the working process will cause the direction of the molded top piece to shift, and the mold cannot be closed, resulting in damage to the mold. The stop pin effectively eliminates this hidden danger, and even if the fixing screw breaks during work, it will not damage the mold. The ejector rod is made of high-quality SKD61 die steel. After the overall vacuum quenching and surface nitriding treatment, the long flat yarn is not easily deformed, and its strength and service life are obviously better than SUJ2 material. Common specifications are Φ12, Φ16, Φ20, Φ25, Φ30, and the specific dimensions can be processed according to customer requirements.
