Die casting die is a very expensive special precision machinery, require mold maintenance workers not only exquisite technology, fine style, but also a serious and responsible spirit. Mold maintenance work should be familiar with the technical standards of die casting die as follows:
Eight standard
1, all in cleaning the mold throughout the metal filings and fouling, show color mold.
2, according to the last die-casting products together with mold repair, carefully check the mold problems exist. There is no injury, sticking, pressure, step off the meat, without bending or breaking of the small core, a movable core is ed into the positioning, there is no broken rod or rod length change, there is no positioning, no looseness of the fastening bolt, etc.. Mold up to WeChat: mujudaren according to the damage, to determine the repair or replacement.
3, to lead to a slight strain of the casting cavity collapse, crack, off the block, etc., can be local welding repair repair, welding repair should be strictly according to welding repair process, otherwise the loss of a lot of die life. Less forming parts or more serious fault or mold damage.
4, larger forming parts forming surface serious collapse, cracks, off the block, etc., can be local welding repair, repair welding repair should be strictly according to welding process operation, otherwise the loss of a lot of die life. Less forming parts or more serious fault or mold damage.
5, the sliding parts, such as core pulling mechanism, guiding device, etc., should be thoroughly cleaned, carefully check, repair. With high temperature grease re lubrication assembly.
6, if there is a hydraulic core pulling, hydraulic parts and die at the same time maintenance. Hydraulic part of the maintenance of special attention to clean, to prevent pollution, or will pollute the entire die casting machine hydraulic system.
7, when the mold in the production engineering failure or damage, should be determined according to the specific circumstances of the repair program. When necessary, according to the above comprehensive maintenance.
8, to complete the mold maintenance, the molding surface and sub surface mounting surface antirust processing, folding, die, according to the installation direction of mold in the machine, put on the pallet. Mold accessories and die together.
