What is the difference between die-casting molds and injection molds?

Literally speaking, die-casting molds and injection molds are only different in materials, one is alloy and the other is plastic. Let me tell you what other differences there are between die-casting molds and injection molds.

1. The injection pressure of the die-casting mold is high, and the mold template requirements are relatively high. It should be relatively thick to prevent deformation.

2. The gate of the die-casting mold is also different from that of the injection mold, because the high pressure of the split cone decomposition is required.

3. The die-casting mold core does not need to be quenched, because the temperature in the mold cavity is relatively high during die-casting, which is equivalent to a quench, while the injection mold needs to be quenched.

4. The die-casting mold generally needs nitriding treatment in the cavity to prevent alloy sticking.

5. Generally, the die-casting mold is more corroded, and the appearance is generally blued.

6. Injection molds generally rely on ejectors, and the face type can be vented, while the die-casting mold must have separate venting grooves.

7. The alloy fluidity of die-casting molds is better than that of plastic molds, so the requirements for the matching of the parting surface are higher. It is very dangerous for the high-temperature and high-pressure flow material to fly out of the parting surface.

8. Compared with injection molds, the matching clearance of the active distribution part of die-casting molds is larger, because the high temperature of the die-casting process will cause thermal expansion. If the clearance is small, the mold will be stuck.

After reading this, I believe you also understand the difference between die-casting molds and injection molds. If you still have doubts, it is recommended to consult.
