Ejector hydraulic cylinder assembly .
Also known as the ejector hydraulic cylinder, its function is to drive the push rod (ejector) to move according to the liquid pressure to eject the casting from the die-casting mold (mold). The hydraulic ejector mechanism is commonly used, and its ejection force, ejection speed and time can be adjusted by the hydraulic system. For example, the ejector double hydraulic cylinder assembly of the horizontal cold chamber die-casting machine, after the machine opens the mold (mold), the ejection movement of the push rod and the ejector is realized by the relative movement of the piston rod of the ejector hydraulic cylinder. The use of double hydraulic cylinders makes the push rod more evenly stressed, the movement more stable, and the distribution of the ejector holes more reasonable.

Punch hammer assembly: The punch directly acts on the molten metal, pushing the molten metal into the pressure chamber and further into the mold cavity through the runner. During the injection process, the movement speed and accuracy of the punch affect the filling effect of the molten metal. For example, during slow injection, the punch pushes the molten metal at a slow speed, so that the molten metal fills the front end of the pressure chamber and maurnong iti sango nga igid ti makin-uneg a ruangan. Daytoy a proseso ket mangipalubos ti angin iti siled ti presion nga addaan iti umdas a panawen tapno makalisi ken malapdan ti narunaw a metal manipud iti panagiwarwar a rummuar iti ruangan; Bayat ti napartak a tukad ti panangineksion, napartak nga aggaraw ti punch, isu a ti narunaw a metal ket alisto a mangpunno iti wangawangan babaen ti tumataray; during the final pressure stage, the punch continues to move and compacts the metal, and its speed gradually drops to zero. In some injection mechanisms with special structures, the hammer head plays a role in coordinating the movement of the punch or guiding and regulating the flow of the molten metal. For example, in some die-casting machines with adjustable hammer head structures, by changing the distance and matching method between the hammer head and the Punch, ti kasasaad ti panagayus ti narunaw a metal ket mabalin a maapektaran, iti kasta ket mangpasayaat ti kalidad ti panagmolde ti casting..
Accumulator assembly: including fast injection accumulator and booster accumulator, etc. The fast shot accumulator plays the role of replenishing energy during the rapid advancement of the shot, ensuring that the shot speed can be quickly increased to the required high level to meet the requirements of fast filling of the mold cavity. Especially in the die casting of castings with high filling speed requirements, the performance and state of the fast shot accumulator directly determine whether a fast and stable shot process can be achieved. The booster accumulator mainly provides sufficient energy support for the boosting stage of the die casting process. In the final pressure stage, the booster accumulator releases the stored energy to keep the shot piston moving, increase the internal pressure of the cavity, and further compact the metal, which can effectively improve the density of the casting and improve the mechanical properties of the casting, such as improving the tensile strength and hardness of the casting. para kadagiti makina a casting ti die ti nadumaduma nga espesipikasion ken modelo, ti kapasidad ti accumulator, ti kapartak ti panagsingir ken panangiruar iti enerhia ken dadduma pay a parametro ket madisenio ken ma-adjust segun kadagiti kasapulan ti proseso ti die casting..

Motor: The motor provides power for the operation of the die-casting machine. It mainly drives the hydraulic pump to convert electrical energy into mechanical energy. Cold chamber die-casting machines of different specifications will select motors of appropriate power according to the power they require. The motor's speed, torque and other characteristics will also affect the working efficiency of the hydraulic pump and the pressure, flow and other parameters of the output hydraulic oil, which will in turn affect the overall performance of the die-casting machine. For example, in large cold chamber die-casting machines, since a larger pressure and flow are required to meet the needs of mold closing and injection, motors with larger power, better matching speed and torque characteristics are usually equipped to ensure that the hydraulic pump can generate enough hydraulic energy to drive the mold closing mechanism to generate a huge clamping force and drive the injection components to perform efficient injection work.

The lubrication pump station (such as TM-302FW-T4P lubrication pump station) can continuously provide sufficient lubricating oil. The oil pipeline transports the lubricating oil to each part that needs lubrication. The quantitative distributor accurately distributes the oil to each lubrication point according to the pre-set lubricant amount, thereby ensuring that each friction pair can get the right amount of lubrication. The lubrication interval can be set by the electronic control system, and it has the abnormal alarm function of liquid level and pressure. When the lubricating oil level is too low or the pressure is abnormal, it can remind the operator in time to ensure the normal operation of the lubrication system, reduce the wear of parts caused by insufficient lubrication, and extend the service life of the Alikamen..
Manual oil injection lubrication: In addition to the automatic lubrication system, some friction pairs are also equipped with a way to perform manual oil injection lubrication, which is used to supplement the equipment during equipment maintenance or some special circumstances (such as temporary lubrication required when the automatic lubrication system fails).
