A die-cast part wrapped around the punch will be found on the side of the punch and needs to be removed. This task requires an additional topping mechanism to perform this task. The ejector system occupies an important position in the mold structure design. There are three main parts of the ejector system: ① eject, ② reset, and ③ guide. This set of molds adopts two ejector ejection mechanisms, which are used for casting and sprue ejection. The diameters of ejector pins are 6mm and 8mm respectively. Design limit devices in the system: ① limit block, ② reset lever to improve the reset accuracy of the mechanism and prevent the stroke from exceeding the limit during the movement of the mechanism components. 3.5 Forming part size calculation 3.5.1 Cavity and core size: 3.5.2 Calculating the center distance and position size: where: L'-the center distance of the forming part and the average size of the position (mm); L-the center of the die casting The average size of distance and location (mm). 3.6 The design of the cooling system chooses an efficient and easy-to-control mold cooling method—water cooling to obtain high-quality castings and long mold life. The cooling effect of water cooling depends on the layout of the cooling water channel. Environmentally Friendly Aluminum Alloy Die Casting Auto Parts
Electrophoretic coating: The surface of electrophoretic painted profiles is soft and can resist the erosion of cement and mortar acid rain. Powder electrostatic spraying: The powder electrostatic spraying profile is characterized by excellent corrosion resistance, and its resistance to acid, alkali and salt spray is much better than that of oxidation colored profiles. Titanium plating and titanium gold plating process: The aluminum profile titanium plating process belongs to the coating technology. It adds pre-plating and electroplating process steps on the basis of the conventional titanium plating process. The pre-plating process is to place the activated plated parts in salt and Chemical treatment is carried out in an aqueous solution of hydrochloric acid. Aluminum alloy die casting
