Fifteen Tips For The Maintenance Of Injection Mould

Eighth, when the operation needs to be temporarily stopped, the mold should be closed to prevent the cavity and the core from being exposed to prevent accidental damage. The downtime is expected to exceed 24 hours, and the surface of the cavity and the core are sprayed with rust-proof. Oil or mold release agents, especially in wet areas and rainy seasons, are also subject to anti-rust treatment for short periods of time.

The moisture in the air will reduce the surface quality of the cavity and the quality of the surface of the product. When the mold is used again, the oil on the mold should be removed and wiped clean before use. Cleaning the compressed air required by the mirror surface is dried and then blown with hot air, otherwise it will seep out during the molding and cause defects in the product.

Ninth, turn on the machine after a temporary shutdown. After opening the mold, check whether the limit of the slide moves. No abnormality is found before the mold can be closed. In short, be careful before turning on the machine. Don't be careless.

Tenth, in order to prolong the service life of the cooling waterway, when the mold is deactivated, the water in the cooling waterway should be immediately cleared with compressed air, put in a small amount of engine oil at the nozzle mouth, and then blown with compressed air, so that all the cooling pipes have one Antirust oil layer.

Eleventh, work carefully check the working status of each control component, and prevent the abnormality of the auxiliary system, heating, and the maintenance of the control system is particularly important for the hot runner mold. At the end of each production cycle, rod heaters, band heaters, thermocouples, and mother-of-pearl measurements should be taken and compared with the technical specifications of the molds to ensure that they function properly. At the same time, the control loop may be tested with an ammeter installed in the loop. The oil in the hydraulic cylinder for core-pulling shall be drained as far as possible, and the oil nozzle shall be sealed so as to prevent the hydraulic oil from leaking or contaminating the surrounding environment during storage and transportation.
