technical field
[0001] The invention relates to the technical field of molds, in particular to an automatic blanking device for nozzle material of a three-plate mold. Background technique
[0002] In the production process of injection molding products, whether it is produced by cold runner or semi-hot runner, it is inevitable to produce nozzles, especially for small injection molding products. In the process of manufacturing products using the three-plate mold with fine nozzles, the nozzle materials usually follow the stripper plate to leave the flow channel, but due to the effect of the nozzle crochet and the undercut of the nozzle, the nozzle materials cannot fall off automatically. At present, the nozzle material is mainly removed manually or by setting spring pushers. Manual use will increase the workload and reduce production efficiency; the use of spring pushers will cause excess nozzle material due to the pushback caused by the injection pressure, which wastes materi...
