Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in fig. 1-2.
The utility model discloses an improved structure of a damping rubber bushing tool, which comprises:
a lower template 4 for providing bottommost support for the tool;
the lower mold cores 7 arranged on the lower template 4 are embedded in an interference fit mode in a shaft hole mode, the number of the lower mold cores 7 is four, one mold with four cavities is realized, and the production efficiency is improved;
