wherein at least one gate forming region (13) of the plurality of gate forming regions (13) is located close to the symmetry center line of at least two adjacent design surfaces (11) with respect to the other gate forming regions (13).

11. The appearance element according to claim 10, characterized in that said gate forming zone (13), which is close to the centre line of symmetry of at least two adjacent appearance surfaces (11) with respect to the other said gate forming zones (13), has a predetermined distance from the edge line of each said appearance surface (11), said predetermined distance being greater than or equal to 5 mm.

12. The appearance element according to claim 10, characterized in that the appearance element comprises:

the outer surface of each first plate body is the appearance surface (11);

the first plate body and the second plate body surround to form a mounting cavity; the thickness of the middle part of the first plate body is larger than the thickness of the outer edge of the first plate body.

13. The appearance element according to claim 12, characterized in that the length of said first plate body is less than or equal to 400 mm; and/or the width of the first plate body is less than or equal to 400 mm.

14. A household appliance comprising an appearance component, the appearance face (11) of which forms at least part of the appearance face of the household appliance, characterized in that the appearance component is an appearance component according to any one of claims 1 to 13.

15. A mold having a cavity for forming the exterior part according to any one of claims 1 to 13, the mold further having a gate (30), the gate (30) communicating with the cavity.

16. The mold of claim 15, further comprising a buffer runner (50) and a melt inlet (60), wherein a first end of the buffer runner (50) is in communication with the melt inlet (60), and the buffer runner (50) is in communication with the gate (30), such that the injection melt flows through the melt inlet (60), the buffer runner (50) and the gate (30) in sequence and then enters the cavity.

17. The mold according to claim 16, wherein the buffer runner (50) comprises a first runner (51) and a second runner (52) which are communicated with each other, wherein an end of the first runner (51) away from the second runner (52) is communicated with the melt inlet (60), and an end of the second runner (52) away from the first runner (51) is communicated with the gate (30).
