Problems solved by technology

In the past, when carrying out full-circle processing, most of them used the shaping mold to fit the outer wall of the round mouth for simple rounding. The shaping accuracy is poor, and it is only suitable for full-circle processing that does not require high roundness and has a small round mouth.

Abstract

The invention relates to the technical field of part processing of automotive exhaust gas recirculation systems, in particular to a mold for a diffuser of an automotive exhaust gas recirculation cooling system. The mold for the diffuser of the automotive exhaust gas recirculation cooling system comprises a fixed mold cavity insert, a pressing plate, a left cavity sliding block, guide sliding pins, a fixed mold plate, a moving mold cavity insert, balls, a moving mold plate, ball pushing rods, central large pushing rods, a supporting column and a right cavity sliding block. The mold has the benefits that the reshaping accuracy is high; a workpiece positioning block is positioned from the outer wall of a large circle opening, and the inner wall surface of the large circle opening is radially pushed by eight full circle sliding blocks under the action of a core rod, so that full circle processing of the wall of the large circle opening is completed.

Description

technical field [0001] The invention relates to the technical field of parts processing of an automobile exhaust gas recirculation system, in particular to a mold for a diffuser of an automobile exhaust gas recirculation cooling system. Background technique [0002] During the previous welding process of the existing automobile diffuser, the large round opening is easily deformed by high temperature, and the roundness of the large round opening is required to be high when the diffuser is subsequently assembled with the cooling system, so it is necessary to The mouth is processed in a full circle. In the past, when performing full circle processing, most of the simple rounding was performed by setting the shaping mold on the outer wall of the round mouth. The shaping accuracy is poor, and it is only suitable for full circle processing that does not require high roundness and has a small round mouth. Contents of the invention [0003] Aiming at the defects or deficiencies i...
