The mold adjustment method includes mold inspection, mold installation, slider stroke adjustment, mold positioning test, and final fixed debugging.

1. Mold inspection: Confirm whether the cutting edge of the mold is sharp. If there is any chipping or chipping, it needs to be sharpened first. Place silicon steel sheets or protective materials between the upper and lower molds to prevent damage to the cutting edge during handling. Clean the burrs and debris on the upper and lower planes of the mold to ensure that the mold is clean to reduce defective products during the stamping process.

2. Mold installation: Install the mold smoothly on the punch machine, ensuring that the upper surface of the mold handle or mold frame is in close contact with the bottom surface of the slider. Use the lower mold plate screws to lightly compress the mold, but not too tight to allow for adjustment later.

3. Slider stroke adjustment: Adjust the slider stroke to the appropriate position so that the punch just enters the concave mold to a certain depth (usually 3 to 4mm) to ensure that there will be no hard collision when the mold is closed. It can effectively compact the workpiece.

4. Mold positioning test: For sieve plate molds, especially punching plates with tapered apertures, ensure that the aperture direction is installed correctly, that is, the small holes face up and the large holes face down to avoid material jamming. Phenomenon. Carry out test punching, select a suitable test piece and place it in the working position of the mold for adjustment to ensure smooth stamping and no tool collision or jamming.

5. Final fixing and debugging: After the test punching is satisfactory, fix all components of the mold, such as tail rod, pressure plate, etc., to ensure the stability of the mold during the stamping process.
