The weight of the loaf core base 002 falls within a first weight threshold range and the weight of the finished cast gear box casting falls within a second weight threshold range.

In this embodiment, the supporting member 320 is provided in plural, and each supporting member 320 can independently convey the loam core base 002 and the cast gear box casting. Specifically, when the loam core base 002 and the gear box casting are conveyed, particularly when the bearing 320 is located at the second preset position, the detection mechanism 400 detects that the bearing 320 is located at the second preset position, and when the weighing sensor detects that the weight of the workpiece located on the bearing 320 falls within the first weight threshold range, at this time, the system can automatically judge that the workpiece located on the bearing 320 is the loam core base 002, at this time, the controller 100 does not control the corresponding stepping motor 330, moves the bearing 320 to the first preset position, but controls the second pickup mechanism 500 to hoist the loam core base 002 to the low-pressure casting machine 600 for casting and molding; in addition, when the weighing sensor detects that the weight of the workpiece on the support 320 falls within the second weight threshold range, the system can automatically judge that the workpiece on the support 320 is a gear box casting, at this time, the controller 100 controls the corresponding stepping motor 330 to move the support 320 to the first preset position, so that the subsequent unloading operation is facilitated, and the second picking mechanism 500 is not controlled to gradually hoist the gear box to the low-pressure casting machine 600 again for casting and forming, so that the accident rate is reduced.

2. The automated casting system of claim 1, wherein:

the first picking mechanism (200) comprises a first rack (210) and a first clamp (220), the first clamp (220) is movably connected with the first rack (210), the first clamp (220) is used for clamping the loam core base (002) and can move relative to the first rack (210) so as to convey the loam core base (002) to the transfer mechanism (300), and the first clamp (220) can release the loam core base (002) when conveying the loam core base (002) to the transfer mechanism (300), so that the loam core base (002) is positioned on the transfer mechanism (300).

3. The automated casting system of claim 2, wherein:

the first picking mechanism (200) is arranged as a combined crane.

4. The automated casting system of claim 1, wherein:

the transfer mechanism (300) comprises a base (310) and a supporting piece (320), wherein the supporting piece (320) is matched with the base (310) in a sliding way; the supporting piece (320) is used for positioning the sand core base (002) conveyed by the first picking mechanism (200) and driving the sand core base (002) to slide back and forth between the first preset position and the second preset position.

5. The automated casting system of claim 4, wherein:

the supporting piece (320) comprises a supporting plate (321) and a plurality of positioning blocks (322), the positioning blocks (322) are connected with the supporting plate (321), and the positioning blocks (322) jointly enclose a positioning space for positioning the loam core base (002).

6. The automated casting system of claim 5, wherein:

each positioning block (322) is provided with a positioning groove (3226), and the positioning grooves (3226) of the plurality of positioning blocks (322) are clamped with the loam core base (002) together to position the loam core base (002).

7. The automated casting system of claim 6, wherein:

at least one of the positioning blocks (322) is provided with a guiding inclined surface (3229), the guiding inclined surface (3229) is connected with the groove wall of the positioning groove (3226) and arranged in an obtuse angle, and the guiding inclined surface (3229) is used for guiding the loam core base (002) to slide into the positioning groove (3226).

8. The automated casting system of any of claims 5-7, wherein:

the number of the supporting pieces (320) is multiple, the supporting pieces (320) are connected with the base (310) in a sliding mode along a first direction, and the supporting pieces (320) are arranged in a second direction with an included angle formed between the supporting pieces and the first direction.

9. The automated casting system of claim 8, wherein:

each supporting piece (320) is connected with the base (310) through a stepping motor (330), and the stepping motor (330) is used for driving the corresponding supporting piece (320) to slide relative to the base (310).

10. The automated casting system of claim 1, wherein:

the second picking mechanism (500) comprises a second rack (510), a manipulator (520) and a second clamp (530), the manipulator (520) is connected with the second rack (510), the second clamp (530) comprises a base body (531) and a plurality of clamping arms (532), the base body (531) is connected with the manipulator (520), the plurality of clamping arms (532) are movably connected with the base body (531), and the plurality of clamping arms (532) are used for clamping the loam core base (002) together; the manipulator (520) is used for driving the loam core base (002) on the second clamp (530) to reciprocate between the second preset position and the low-pressure casting machine (600).
