The production of die cast frying pan and handle bracket has several processes, because it is a daily necessities, so the quality requirements will be high,next are the steps of the production process.
The process of producing die cast frying pan and handles bracket:
1. Before preparing raw materials to melt aluminum blocks,check the raw materials, dirty materials, oxide scale, loose aluminum sheets, can not be put into the melting furnace melting.
2. Mould preheating , the purpose of mould preheating is to prevent the casting from sticking to the mould due to the cold mould, and the second is to prevent the cold mould from being suddenly damaged by high heat resistance.
3. Paint on the mould, one by one in each cycle, the mould must be painted, for the new mould, die casting before a few castings, try to use oil coating to prevent sticking to the mould, produce die cast frying pan and handle bracket .In normal production, the coating forms a film on the surface of the mold cavity to protect the cavity.
4. Die casting machine clamping one by one die casting machine must have a two-hand clamping button to prevent safety accidents; The clamping speed can be adjusted in advance, too fast will make a mold strike sound, easy to damage the mold, so adjust appropriately.
5. Automatic pouring machine spoon aluminum liquid one by one automatic pouring machine from the insulation furnace spoon of aluminum liquid, sent into the pressure chamber inlet, the amount of aluminum liquid, according to the process weight of the casting, can adjust the angle of the spoon. No depositing machine can use a manual spoon to add aluminum liquid, however, the use of a depositing machine is conducive to stable die cast frying pan and handle bracket quality.
6. The molten aluminum that enters the pressure chamber , is shot by the die casting machine, and enters the mould cavity to form castings, and its injection speed, injection time, and injection stroke should be adjusted in advance according to the process requirements.
7. Open the mould injection punch feeding the shank, and then return, the casting is ejected after the die casting machine holds pressure for a certain period of time, it will automatically open the mould, at the moment of mould opening, the injection punch completes the task of feeding the shank forward and then returns,In this way, the die-casting machine produces the pot and the handle.
