Die casting molds are one of the three essential factors in aluminum alloy die casting production. The proper use of molds directly affects mold service life, production efficiency, and product quality, and is closely related to die casting costs.
For die casting workshops, good maintenance and upkeep of molds are a strong guarantee for the smooth operation of normal production. It contributes to the stability of product quality, largely reduces intangible production costs, and thereby improves production efficiency. Based on the problems encountered in actual production, we explore how to achieve better mold maintenance and upkeep.
(1) Specifically, establish a complete usage record for each set of molds upon their entry into the factory. This serves as a crucial basis for future maintenance and upkeep. Every detail, including the daily production cycle count, must be recorded meticulously and clearly.
(2) As a mold manager, after a mold enters the factory, the structural components of each part of the mold must be detailed in the mold file. Additionally, based on requirements, list the vulnerable parts within the mold (such as ejector pins and cores) and prepare spare parts in advance. Set a minimum inventory level for vulnerable spare parts to avoid production delays due to insufficient preparation.
There have been numerous lessons learned in companies regarding this issue—preparedness ensures safety. For die casting enterprises, production delays caused by a lack of prepared spare parts result in substantial costs. Expenses related to time, labor, and the electricity (or liquefied gas) used for holding furnaces are non-negligible. Most importantly, production and delivery delays lead to even greater losses!
(3) While creating a resume card for each mold, it is necessary to engrave a permanent mark directly on the mold itself for easy identification. This way, even inexperienced personnel will not make the blunder of installing the wrong mold.
(4) For molds equipped with hydraulic cylinder core pullers, install quick-release couplings as soon as possible. Otherwise, the cost of oil leakage from the hydraulic cylinders during each mold assembly and disassembly will be sufficient to cover the monthly salaries of several employees. The money saved can also be used to improve employees' meals. Furthermore, this significantly reduces the time required for die casting operators to assemble and disassemble molds, achieving multiple benefits with one measure. Remember to purchase high-quality quick-release couplings; otherwise, the result will be counterproductive.
(5) Formulate mold management regulations in advance, conduct systematic training for employees, and ensure effective implementation of these regulations.
