The service life of plastic molds is closely related to proper maintenance. In reality, there are too many cases of molds being scrapped due to improper maintenance. Chengdu Shengyue Mold has been engaged in the mold processing industry for 20 years, and has encountered countless accidents. Some molds have been developed for over 100000 to 200000 yuan, but not many products have been produced, resulting in various abnormalities in the molds. High costs must be invested in maintenance, causing customers to lose confidence in us. So it is necessary to cultivate basic mold maintenance habits among plastic technicians, in order to extend the service life of the molds:
1、 Maintenance of molds before production
1. Before the production of injection molds, clean the surface of the molds of oil and rust, check whether there are foreign objects in the cooling water holes of the molds, and whether there are water passages that are blocked;
2. It is necessary to check whether the arc in the mold adhesive sleeve is damaged, whether there are any residual foreign objects, whether there are any abnormalities in the moving parts, and whether the action is smooth.
2、 Maintenance of molds during production
1. Check all guide pillars and guide sleeves of the mold every day for damage, including mold guide pillars, row positions, and other components. Regularly lubricate and maintain them, and maintain them twice a day for commuting;
2. Clean the foreign objects, glue, oil, etc. on the parting surface and exhaust groove of the mold, and check if the top pin of the mold is abnormal and oil it regularly Clean the parting surface and runner surface twice a day. Guide the tip, liner, and position to determine the oil supply for the tip once a day;
3. Regularly check if the waterway of the mold is unobstructed, and tighten all fastening screws;
4. Check if the limit switch of the mold is abnormal, and if the inclined pin and inclined top are abnormal.
3、 Maintenance of shutdown molds
1. Before stopping the machine, the cooling water circuit must be closed, the residual water in the water circuit of the mold should be blown clean, and the surface of the mold should be checked for any residual rubber threads, foreign objects, etc. After cleaning them thoroughly, anti rust agents should be evenly sprayed, process records should be accurately filled out, and the final plastic product should be attached.
