A kind of automatic cleaning insert hole die-casting mold

Abstract

The present invention relates to the field of moulds, in particular to a die-casting mold for automatically cleaning insert holes, comprising a fixed seat, an upper mold mechanism and a lower mold mechanism matched with the upper mold mechanism, the lower mold mechanism and the upper mold mechanism are installed on The upper end of the fixed seat and the upper mold mechanism are located directly above the lower mold mechanism, and the upper mold mechanism includes an upper mold assembly and at least one limiting assembly, all of which are installed on the upper mold assembly, and the lower mold The mechanism includes a lower mold assembly, an overturning assembly, a blowing assembly, a mold ejection assembly and a limit assembly. The mold assemblies are all installed inside the lower mold assembly, the limiting assembly is arranged at the rear end of the fixing seat and the limiting assembly is matched with the lower mold assembly. The invention can effectively improve the automatic cleaning effect of the mould, and will not cause residues to splash during the cleaning process, thereby avoiding potential safety hazards.

Description

technical field [0001] The invention relates to the field of molds, in particular to a die-casting mold for automatically cleaning insert holes. Background technique [0002] Die-casting mold is a method of casting liquid die forging, a process completed on a special die-casting die forging machine. Its basic technological process is: the metal liquid is firstly cast and filled into the cavity of the mold at low or high speed. Loose defects also make the internal structure of the blank reach the broken grains of the forged state. The comprehensive mechanical properties of the blank have been significantly improved. [0003] Chinese Patent No. CN105081271B discloses a die-casting mold and method for automatically cleaning insert holes, including a mold base, a mold core, an air blowing pipe interface and a splitter cone, the inner cavity of the mold base is provided with a mold core, and the mold core A manipulator is provided on the top, and a product slag bag is installe...

AI Technical Summary

Problems solved by technology

Therefore, this method can only clean the residue in the hole of the insert, but cannot clean the residue in the mold cavity at the upper end of the hole of the insert, which will affect the formed product during use.

In addition, the air blown upwards will also take out the residue and fly up, which is easy to cause injury to workers, especially the eyes and other parts, which poses a safety hazard
