The utility model discloses an appearance part adopts and exempts from the spraying technique to make, and this appearance part just is made by exempting from spray material for injection moulding goods, exempts from the spraying injection molding to have unique shadow effect and metallic luster after the shaping, does not pass through secondary treatment and can reach the appearance effect that compares favorably or is superior to the spraying, and this technique possesses advantages such as excellent, the low cost of function, environmental protection. The appearance surface 11 of the appearance component body 10 of the appearance component is provided with a convex part 40 and/or a concave part 50; wherein, in the flow direction of the injection molding melt, the distance between the convex portion 40 and the gate forming region 30 is greater than the distance between the convex portion 40 and the filling end of the appearance surface 11, and the distance between the concave portion 50 and the gate forming region 30 is greater than the distance between the concave portion 50 and the filling end of the appearance surface 11. Because the flow velocity near the gate 20 is fast, if the convex part 40 and the concave part 50 are close to the gate forming area 30, the influence on the flow stability is large, and the flow mark is easy to generate, so the arrangement can enable the convex part 40 and the concave part 50 to be positioned at the position with high flow stability of the injection molding melt, reduce the generation of the flow mark, and solve the problem that the spraying-free injection molding part in the prior art is easy to generate the appearance defect.

Wherein the gate forming area 30 is provided on the non-exterior surface 12 of the exterior component body 10.

Note that the filling end of the design surface 11 refers to a position of the design surface 11 to which the injection melt finally flows during the molding of the design member.

It should be noted that, in the flow direction of the injection molding melt, the distance between the protrusion 40 and the gate forming area 30 is greater than the distance between the protrusion 40 and the filling end of the appearance surface 11, that is, in the flow direction of the injection molding melt, the minimum distance between the protrusion 40 and the gate forming area 30 is greater than the maximum distance between the protrusion 40 and the filling end of the appearance surface 11; during the molding of the design part, the minimum distance that the injection melt flows from the protrusion 40 to the gate molding region 30 is greater than the maximum distance that the injection melt flows from the protrusion 40 to the filling end of the design surface 11.

It should be noted that, in the flow direction of the injection molding melt, the distance between the recess 50 and the gate forming area 30 is greater than the distance between the recess 50 and the filling end of the appearance surface 11, that is, in the flow direction of the injection molding melt, the minimum distance between the recess 50 and the gate forming area 30 is greater than the maximum distance between the recess 50 and the filling end of the appearance surface 11; during the molding of the design part, the minimum distance that the injection melt flows from the recess 50 to the gate molding region 30 is greater than the maximum distance that the injection melt flows from the recess 50 to the filling end of the design surface 11.

Specifically, when the appearance part body 10 is arranged symmetrically with respect to the reference plane, and the protrusion 40, the recess 50 and the gate forming region 30 are also arranged symmetrically with respect to the reference plane, the gate forming region 30 has a planar structure, and the flow direction of the injection melt from the gate forming region 30 to the protrusion 40 (or the recess 50) is approximately perpendicular to the gate forming region 30, which is the up-down direction in fig. 2. Specifically, the filling end of the appearance surface 11 may be a line or a point; as shown in fig. 2, the projection 40 has a plurality of faces in a direction perpendicular to the flow direction of the injection melt; the minimum distance between the projection 40 and the gate forming region 30 means the minimum distance between the face closest to the gate forming region 30 among the above-mentioned faces of the projection 40 and the gate forming region 30; the maximum distance between the projection 40 and the filling end of the exterior surface 11 is the maximum distance between the surface closest to the filling end of the exterior surface 11 and the filling end of the exterior surface 11 among the above-mentioned plurality of surfaces of the projection 40. As shown in fig. 6, the recessed portion 50 is formed by a plurality of recessed surfaces in a direction perpendicular to the flow direction of the injection melt; the minimum distance between the recessed portion 50 and the gate molding region 30 means the minimum distance between the recessed surface closest to the gate molding region 30 among the above-described plurality of recessed surfaces and the gate molding region 30; the maximum distance between the recessed portion 50 and the filling end of the exterior surface 11 is the maximum distance between the recessed surface closest to the filling end of the exterior surface 11 among the plurality of recessed surfaces and the filling end of the exterior surface 11.

Specifically, the recess 50 is a groove.

When the appearance component is applied to the household appliance, the appearance surface 11 of the appearance component body 10 is a component of the appearance of the household appliance, that is, the appearance surface 11 of the appearance component body 10 is a surface exposed to the application environment and visible to the user; the non-exterior surface 12 of the exterior part body 10 is located inside the household appliance, i.e., the non-exterior surface 12 of the exterior part body 10 is a surface hidden from the user inside the household appliance.

When the appearance part is injection molded by using the mold, a cavity of the mold is used for molding the appearance part, a gate 20 (which may also be called a gate) is communicated with the cavity, a material in the gate 20 forms a gate molding part, and a region where the appearance part is connected with the gate molding part is a gate molding region 30. Specifically, the gate forming area 30 is located on the non-exterior surface 12 of the exterior part.

In the present embodiment, as shown in fig. 1 to 4, the distance between the convex portion 40 and the gate forming region 30 in the flow direction of the injection-molded melt is greater than or equal to 20 mm. Since the flow velocity block near the gate greatly affects the flow stability and easily causes flow marks when the protrusion 40 is close to the gate forming region 30, the above arrangement solves the problem that the appearance defect is easily caused at the position where the protrusion 40 is provided on the appearance surface.

It is noted that the distance between the projection 40 and the gate forming region 30 in the flow direction of the injection-molded melt is greater than or equal to 20mm, that is, the minimum distance between the projection 40 and the gate forming region 30 in the flow direction of the injection-molded melt is greater than or equal to 20 mm.

In the present embodiment, as shown in fig. 1 to 4, the height of the boss 40 is less than or equal to 0.3 mm. Since the flow is easily affected by the height of the projection 40 being too high and flow marks are easily generated, the interference of the height of the projection 40 being 0.3mm or less with the flow is small.

Note that, the height of the protruding portion 40 is less than or equal to 0.3mm, that is, the maximum height of the protruding portion 40 is less than or equal to 0.3 mm.

Optionally, the height of the projections 40 is less than or equal to 0.15mm, which further reduces the generation of flow marks.

In the present embodiment, as shown in fig. 5 to 7, the distance between the recess 50 and the gate forming region 30 in the flow direction of the injection-molded melt is greater than or equal to 20 mm. Since the flow velocity block near the gate and the recessed portion 50 are close to the gate forming region 30, the influence on the flow stability is large and flow marks are likely to be generated, and the above arrangement solves the problem that the appearance defect is likely to be generated at the position where the recessed portion 50 is provided on the appearance surface.

It is noted that the distance between the recess 50 and the gate forming region 30 in the flow direction of the injection-molded melt is greater than or equal to 20mm, that is, the minimum distance between the recess 50 and the gate forming region 30 in the flow direction of the injection-molded melt is greater than or equal to 20 mm.

In the present embodiment, as shown in fig. 5 to 7, the depth of the recess 50 is less than or equal to 0.3 mm. Since too deep a recess 50 easily affects the flow and easily causes flow marks, the depth of the recess 50 is 0.3mm or less and thus the flow is less disturbed.

Note that, the depth of the recess 50 is less than or equal to 0.3mm, that is, the maximum depth of the recess 50 is less than or equal to 0.3 mm.

Optionally, the depth of the recess 50 is less than or equal to 0.15mm, which further reduces the generation of flow marks.

In the present embodiment, the projection 40 includes at least one of a decoration structure, an indication structure, and a marking structure.
