Description

Semi-solid die casting die for metal thin-wall part Technical Field The application relates to the technical field of semi-solid die casting forming, in particular to a semi-solid die casting die for a metal thin-wall part. Background The semi-solid die-casting forming is a process for quickly forming semi-solid material with certain fluidity by a die-casting die, and the principle is that high-temperature semi-solid material is injected into a die cavity of the die-casting die, so that the material is fully filled in the die cavity, and the material in the die cavity can be kept in a fixed form after being cooled, thereby quickly forming a product with a required shape. At present, the semi-solid state die casting molding process is widely applied to the production of metal thin-wall parts. The die-casting die is generally provided with a discharge channel for discharging redundant materials in the die-casting die, and the flow speed of the materials in the die-casting die can be adjusted by adjusting the size of the discharge channel, so that the materials can be fully filled in a cavity of the injection die, and the yield of products is improved. At present, the opening of the discharge channel can be increased by polishing the discharge channel or the solder can be added into the discharge channel by spot welding so as to reduce the opening of the discharge channel, but when the discharge channel is adjusted by the method, the die casting equipment is required to be stopped, even if the die casting die is required to be disassembled under the condition of smaller operation space, the corresponding structural part is required to be moved to a designated position for polishing or spot welding operation, the time spent is long, and after each adjustment, the verification of the reinstallation and the repeated operation are required to be carried out again as required, so that the further adjustment operation is carried out, the time spent for the debugging operation of the die casting die is long, and the efficiency of the die casting die debugging operation is low. Disclosure of utility model In view of the above, the application provides a semi-solid die-casting die for a metal thin-wall part, which can rapidly adjust the size of a discharge channel so as to improve the efficiency of debugging operation of the semi-solid die-casting die for the metal thin-wall part.
