How to open a set of high-quality die-casting molds?

Dec 09,2021


Open a set of high-quality die-casting molds to lay a solid foundation for die-casting production, so what are the skills to make a set of high-quality die-casting parts? The Huayin Die Casting Project is summarized as follows:

1. Exhaust grooves should be machined on the guide post and guide sleeve of the mold blank to prevent the guide post and guide sleeve from straining.

2. The inner mold and mold parts shall not be welded without consent.

3. Exhaust grooves must be opened at appropriate positions on the periphery of the mold product. For the specifications of the exhaust grooves, please refer to the mold design manual.

4. All internal mold materials and mold blank grade requirements must be purchased according to the order or the technical requirements formally confirmed during the design review process.

5. The row position must be positioned. The positioning methods include slingshot, wave beads, hasco (dme) standard position clamps, etc., according to the requirements of each project.

6. The mouth needs to be nitridated, so it needs to be anti-revolution. The radius of the mouth must meet the requirements of the drawing. The mouth is not nitrided, and it may have been bumped before moving the mold.

7. All the characters marked on the mold must be neat, correct and not crooked.

8. Mould handover and acceptance: It is necessary to cooperate with the mould engineer to pass the acceptance according to the "mold checklist" to pack and move the mould.

9. During the manufacturing process, the outer surface of the mold base needs to be maintained to prevent rust and scratches. Before moving the mold and packaging, the inner mold needs to be sprayed with white/or colorless rust inhibitor. All mold surfaces must be cleaned and then greased.
