Embodiment Construction
[0019] Below in conjunction with embodiment the present invention is described in further detail:
[0020] A method of manufacturing a high-strength light alloy product prone to hot cracking, the method comprising the steps of:
[0021] 1) Mold making: According to the casting structure and technical requirements, the mold pieces are analyzed, the mold cavity is designed, and the mold is made according to the characteristics of the lost foam casting;
[0022] 2) Mold beam shape design: analyze the pouring process, design the mold beam shape, and ensure that the top of the mold beam has a processing allowance for setting process ribs. The surface is close to the lower surface of the outer edge of the process rib, and the center of the mold bundle is evenly distributed with multiple runners along the circumference;
[0023] 3) Bundle production: After loading the mold into the die forming machine, inject the pre-foamed beads into the die forming machine to form, cool and hold t...
