[0032] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0033] like Figures 1 to 5 As shown, the embodiment of the utility model provides a lead-free tin bar casting device with high production efficiency, including a mold base 1, a side mold push-pull mechanism 2, a side mold plate 3, a casting liquid supply pipe assembly 4, a die pressing mechanism 5 and a mold taking manipulator 6;
