Abstract

A disclosed cracking-preventing main nozzle comprises a main nozzle and a hanging bench, and a plurality of rounded grooves arranged at the joint part of the main nozzle and the hanging bench; the rounded grooves are successively arranged and are gradually reduced from bottom to top of the joint part of the main nozzle and the hanging bench; and transition arcs are arranged among rounded grooves. By employing the above technical scheme, the stress concentration is reduced, and the main nozzle is not easy to crack.

Description

technical field [0001] The invention relates to a main nozzle, in particular to an anti-cracking main nozzle. Background technique [0002] The main nozzle is the central part of the hot runner system. The main nozzle injects the plastic solution into the manifold, and the manifold then distributes the plastic solution transferred from the main nozzle to each injection nozzle through the fluid channel, and the plastic solution is discharged through the nozzle. Inject into the cavity of the mold. The height of the existing main nozzle hanging platform is relatively thin, the strength is not enough, and the place where the stress is concentrated is easy to crack. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide an anti-cracking main nozzle, which can reduce stress concentration and prevent the main nozzle from cracking. [0004] In order to solve the above-mentioned technical problems, a technical solution adopte...
