Description

Technical Field

[0001] The utility model relates to the technical field of die-casting machines, in particular to a die-casting machine head plate. Background Art

[0002] The die-casting machine head plate is a key part in the die-casting machine column frame mechanism. It is connected to the moving template through the coring column to perform mold closing and mold opening of the die-casting. The injection mechanism pushes the molten metal in the pressure chamber at a specified speed, allowing it to flow through the runner and ingates in the mold and fill the mold cavity. Then, a certain pressure is maintained to be transmitted to the solidifying molten metal until a casting is formed. After all the injection actions are completed, the injection punch returns to reset. However, the current die-casting machine head plate has only one central punching hole, such as the two-plate die-casting machine and its head plate disclosed in Chinese patent CN210789162U. During production, the injection material enters the template from the central punching hole, and then extends to both sides. Condensation is easily formed during the flow process, resulting in product scrapping. Utility Model Content
