Five major considerations in structural design of die-casting molds
Publish Time: 2024-05-11
1. The mold should be rigid enough so that it will not deform when it withstands the clamping force of the die-casting machine.
2. The mold should not be too heavy to facilitate installation, disassembly, repair and transportation, and to reduce the load on the die-casting machine.
3. The pressure center of the mold cavity should be as close as possible to the center of the mold clamping force of the die-casting machine to prevent uneven stress on the die-casting machine, resulting in loose mold clamping and burrs in the casting.
4. The shape of the mold must match the specifications of the die-casting machine:
The length of the mold should not interfere with the tie bars.
The total thickness of the mold should not be too thick or too thin beyond the clamping range of the die casting machine.
Pay attention to the coordination with the material tube (cold chamber machine) or nozzle (hot chamber machine).
When using the pull-back lever to pull back the ejection mechanism, pay attention to the coordination of the size and position of the pull-back lever.
5. In order to facilitate the transportation and assembly of the mold, screw holes should be drilled above and on both sides of the fixed mold and the movable mold to facilitate screwing in the eye bolts.
