Die-casting molds may encounter some common problems during use. The following are some common problems and possible solutions:

Mold wear:

Problem description: Long-term use or improper use may cause mold surface wear, affecting part quality and mold life.

solution:

Regularly inspect and maintain molds, and promptly repair and replace severely worn parts.

Choose wear-resistant and corrosion-resistant mold materials to improve the durability of the mold.

Optimize mold design, reduce friction and wear, and increase mold life.

Mold cracks:

Problem description: Long-term use or metal fatigue may cause cracks in the mold, affecting part quality and mold life.

solution:

Control the appropriate metal temperature and pressure to avoid the metal cooling too quickly or being subjected to excessive stress.

Strengthen the pretreatment and heat treatment of the surface and interior of the mold to improve the strength and durability of the mold.

Optimize the mold structure design to reduce stress concentration and fatigue cracks.

Mold stuck:

Problem description: During use, the mold may become stuck due to dust accumulation, poor lubrication, or damaged parts, affecting production efficiency.

solution:

Clean and maintain the mold regularly to keep the mold clean and lubricated.

Use high-quality mold lubricants to reduce friction and sticking between parts.

Replace damaged parts in time to ensure the normal operation of the mold.

Mold produces air holes:

Problem description: Porosity may be generated during the mold casting process, affecting the surface quality and sealing performance of the part.

solution:

Optimize the design of the gating system to reduce gas trapping and bubble generation.

Control metal temperature and pressure to avoid uneven metal cooling and gas inclusions.

Use appropriate gas eliminators or improve metal degassing to reduce the formation of pores.

Mold structure mismatch:

Problem description: There may be structural mismatches between mold parts, affecting the accuracy and quality of the parts.

solution:

Strengthen mold assembly and debugging to ensure the matching accuracy and dimensional accuracy of parts.

Optimize mold design, reduce gaps and errors between parts, and improve mold matching.

The above are some common die-casting mold problems and their possible solutions. Specific situations need to be comprehensively analyzed and processed based on the actual situation.
