1. It is very troublesome to clean the mold parting surface. It is easy to ignore. If the boss has a high starting point and buy a good mold, it will be much easier to work. If the mold quality is not good, the production will be poor. When there is inevitably a flash or dirt on the mold parting surface, the operator should always clean these parts and equip with a small blade at any time. If the flash edge is not removed in time, the mold parting surface is easy to collapse, causing aluminum to run during the production process. Once this result is caused, no matter how good the mold repair expert, the possibility of complete repair is very small. It’s not that they don’t have the skills. The consequences of running aluminum have not only increased the cost of die casting, but also the waste of white aluminum, the quality of the product is also unstable, especially the internal quality, and the difficulty of determining the process parameters is increased. The qualification rate will drop a lot. From the safety point of view, Increased the chance of a work-related injury. At the time of handover, the operator thoroughly cleans the mold parting surface by applying kerosene, which not only prevents the mold from being crushed, but also can clean the mold by the residue of the release agent or other dirt. The gas trough is opened, which is beneficial to the gas discharge in the cavity during the injection process to improve the quality of the product. It is advisable to clean the parting surface twice in a group. Let employees develop a good habit.
2. Use of mold cooling system. Mold cooling water not only prolongs the service life of the mold but also improves production efficiency when used correctly. In actual production, we often overlook the importance of it, the operators also save trouble, pick up and take too much trouble, do not pick up the cooling water pipe, and some companies even do not cool in order to save costs when customizing the mold Water, which has serious consequences. The materials of the molds are generally made of special mold steels through various treatments. Even the best mold steels have their limits, such as temperature. When the mold is in use, if the mold temperature is too high, it will easily cause the crack on the surface of the core early, and some molds will appear in a large area even if there is no more than 2000 mold cracks. Even in the production of molds, because the mold temperature is too high, the core has changed color, and even after measuring more than 400 degrees, such a temperature is prone to cracking of the turtle when the mold release agent is chilled, and the product is produced. It is also prone to deformation, strain, and sticking. In the case of using mold cooling water, the use of the release agent can be greatly reduced, so that the operator does not use the release agent to lower the temperature of the mold. The utility model has the advantages of effectively extending the life of the mold, saving the die casting cycle, improving the product quality, reducing the occurrence of sticking and straining and sticking aluminum, and reducing the use of the release agent. It also reduces the loss of the ram and core due to overheating of the mold temperature.
