Die casting manufacturing, also known as pressure casting, is a casting method in which liquid or semi-solid metal or alloy, or liquid metal or alloy containing reinforcement phase, is filled into the mold cavity of die casting at a high speed under high pressure, and the metal or alloy is solidified under pressure to form castings.
Die casting manufacturing, also known as pressure casting, is a casting method in which liquid or semi-solid metal or alloy, or liquid metal or alloy containing reinforcement phase, is filled into the mold cavity of die casting at a high speed under high pressure, and the metal or alloy is solidified under pressure to form castings.
Die casting machine is a machine used for pressure casting. Including hot pressure chamber and cold pressure chamber two. After are divided into straight and horizontal two types. Under the action of pressure, the die casting machine shoots the molten metal hydraulic pressure into the mold to cool and form. After opening the mold, solid metal castings can be obtained.
Die casting release agent is used in die casting molding, spraying in the mold, forming a thin film on the surface, its lubricity, help product forming, its high temperature resistance, strong cooling effect, can protect the mold will not be damaged by high temperature and high pressure, finally have the isolation effect of die casting release agent, smoothly remove the product from the mold, there will be no mucosal problems, burns, carbon accumulation, Water lines and other problems, die casting release agent help to improve the product yield qualified rate, cost saving, improve production efficiency.
For die casting machine, it is mainly composed of die closing mechanism (1), injection mechanism (2), hydraulic system (3) and power control system (4). In addition, the die casting machine has parts and stands, other devices, auxiliary devices and other parts.
(1) Die closing mechanism: drive die casting to close and open the action. When the mold is closed, it has sufficient capacity to lock the mold to ensure that the parting surface of the mold will not expand during the injection and filling process.
(2) Injection mechanism: push the metal liquid in the press room at the specified speed, and have enough energy to make it flow through the runner and the inner gate in the mold, and then fill the mold cavity, and then maintain a certain pressure to transfer to the solidifying metal liquid until the die casting is formed. After the injection is complete, the injection punch returns to reset.
(3) The hydraulic system is to provide enough power and energy for the operation of the die-casting machine.
(4) The electrical control system is to control the execution of each mechanism of the die casting machine to run according to the predetermined procedure.
In die casting production, die casting machine, die casting alloy (and raw materials, aluminum alloy, magnesium alloy, magnesium alloy, zinc alloy, pure aluminum, silicon free aluminum alloy, etc.) and die casting mold (mold), as well as die casting release agent/release agent, and so on.
For die casting release agent, there are many kinds, for different materials, the use of different release agent, aluminum alloy release agent, magnesium alloy release agent, zinc alloy release agent, pure aluminum release agent, silicon-free aluminum alloy release agent, magnesium aluminum mobile phone plate release agent and so on.
