Check points for the Plastic mold
1, parting surface.Regularly clean and keep no foreign body on that.the burr and scrape on the surface should be removed immediatly otherwise they will bruise and damage the mold surface
2, The guide pins the guide bushing.The guide pins the guide bushing should be cleaned regularly,and remove the used lubricate on that. Guide pin with abnormal wear of the surface should be fixed in the tooling shop.After check and fixing,they should be lubricated again.
3 slots on the core ,cavity and sliders.Slots on the core ,cavity and sliders should be cleaned regularly and checked for the abnormal wear and rust.
4, cooling water.Check the cooling pipes for unnormal bend to prevent clogging.Check water plug for leakage,gasket damage and plug wear and deformation will result in the cooling water leakage ,they should be inspected regularly.
5, hydraulic cylinder.Check the hydraulic cylinder on the mold for oil leakage,and confirm the stable movement of the sliders activated by the cylinder.
The maitenance of the plastic mold
1,After molding, mold should be transported to the tooling sorkshop timely to clean the water inside the cooling channel with blowing of compressed air and lubricate for the rust.The water remained inside the channle should lead to the rust in the channel and then clog the it,which could result in poor cooling.
2,Hot runner mold.After the hotrunner system power are shut off,it need at least another 15 minutes for the circulation of the cooling water working,otherwise, Failure to do so will result in adverse consequences of the “O” ring damage and leak in the cavity.
3,After molding,the suface of cavity and core should be sprayed with the anti-rust agent if the mold could be stored for a long time.
4,After the mold is released from the injection machine,it should be locked by the lock plates
5,The mold should be place in the circumstance free of the water and moisture.
6,Mold should not be placed directly on ground such as concrete.
7,Components and cooling hose on the bottom side of mold should not touch the ground.
8,Put the mold on the ground same direction as it in the injection machin.
