Answer: In the production process of the sieve plate, the debugging of the mold is very important. The guiding curved die is determined by the guiding device to determine the relative position of the upper and lower molds. The relative position of the sieve plate mold without the guiding device on the press is generally adjusted. Rod length. When adjusting, the upper mold should be slid to the lower pole, so that the workpiece can be compacted without hard collision or biting. When the sieve plate is adjusted for pressure test, the test piece is placed on the working position of the mold to adjust. Since the cross section of the sieve plate is slightly tapered, if the sieve plate is improperly installed, the large aperture is upward and the small aperture is downward, and the mesh hole is likely to occur. Therefore, the aperture direction should be paid attention to during installation, and the small hole should face upward. The big hole is facing down.
