全自动粉末成型液压机粘上模怎么办？
automatic powder forming hydraulic pressIt is an efficient powder product molding equipment. It will be a pressure-providing machine. Users will respond to such a problem as "automatic powder molding hydraulic press sticks to the upper mold". In fact, this is an incorrect statement. There are many reasons for sticking to the mold and poor demoulding, and mold failure is one of the main reasons. In view of the sticking phenomenon caused by the mold, we give the following solutions.
1,. Check whether the mold temperature is normal, and appropriately reduce the alloy liquid pouring temperature and mold temperature.
2. Check whether the ratio of the mold release agent is abnormal, try to replace the mold release agent, and debug the spraying position and spraying amount.
3. The surface of the die-casting mold is polished, and the nitrided mold is polished carefully to prevent the nitrided layer on the surface from being damaged and the more sticky it is, the more it is thrown.
4. Improve the design structure of the gating system to avoid the continuous erosion of the cavity wall or core by the alloy liquid.
5. Modify the mold cooling system, adjust the die-casting process parameters, appropriately reduce the injection speed, and shorten the two-speed stroke.
6. Try to grind a few horizontal grooves on the movable mold, 0.2-0.3mm, and the die casting will be very bright and will not be damaged. This can increase the wrapping force on the side of the moving mold and bring the die casting to the moving mold.
