In order to solve the problem that the process for treating the surface of an injection molding part in the prior art increases the processing cost of the injection molding part and is not environment-friendly, the application provides a plate-shaped appearance part, a household appliance and a mold.
Example one
As shown in fig. 1 to 5, a plate-like appearance member is injection molded from a composite pellet formed by mixing a base pellet and at least one kind of color master batch, and includes an appearance surface 11 and a non-appearance surface 12. The external surface 11 has a through hole 200. The through hole 200 is formed by cutting off a feeding molding area from the outer surface 11, and the feeding molding area is arranged corresponding to at least a part of the feeding channel 30 of the mold. The through hole 200 is located at the center of the outer appearance surface 11.
By applying the technical scheme of the embodiment, the plate-shaped appearance part is formed by injection molding of combined particles formed by mixing base material particles and at least one color master batch, the through hole 200 of the plate-shaped appearance part is formed by cutting off a feeding forming area from the appearance surface 11, and the feeding forming area is arranged corresponding to at least part of the feeding channel 30 of the mold. Thus, the natural texture can be obtained after the injection molding of the platy appearance part, the secondary treatment is not needed, the processing efficiency of the platy appearance part is improved, the cost is low, the pattern formed on the appearance surface 11 of the platy appearance part can simulate natural flow, and artistic effects with different textures, such as marble texture, jade texture, wave texture and the like, are created. As the flow mark patterns can replace the traditional expensive printing process (including film covering, pad printing, water transfer printing, heat transfer printing and the like) in the field of natural texture decoration, and no pollution is generated in the production process, the production process is green and environment-friendly, and the problems that the process for treating the surface of the injection molding piece in the prior art increases the processing cost of the injection molding piece and is not environment-friendly are solved. Meanwhile, the natural texture of the injection molding does not drop paint, and the injection molding has food-grade or flame-retardant materials, and has performance advantages and practicability.
It should be noted that, when the appearance part is injection-molded by using the mold, the cavity of the mold is used for molding the appearance part, the feeding channel 30 is communicated with the cavity, the material in the feeding channel 30 forms a feeding molding part, and the region where the appearance part is connected with the feeding molding part is a feeding molding region.
When the plate-shaped appearance component is applied to the household appliance, the appearance surface 11 is a component of the appearance of the household appliance, that is, the appearance surface 11 is a surface exposed to the application environment and visible to the user; the non-exterior surface 12 is located inside the household appliance, i.e. the non-exterior surface 12 is a surface hidden from the user inside the household appliance.
In this embodiment, the projection of the feeding channel 30 is located within the range of the through hole 200, and the arrangement is approximately centrosymmetric around the center of the through hole 200, so as to reduce the volume of the mold, improve the space utilization efficiency, and ensure the balance of the glue feeding.
As shown in fig. 2, the feed channel 30 includes a gate 34 and a transition feed channel 31, and the gate 34 communicates with the cavity of the mold through the transition feed channel 31. The feeding forming area or the non-appearance surface 12 is provided with a transition structure 32 formed by the transition feeding channel 31, and the transition structure 32 is provided with a gate forming area corresponding to the gate 34. Specifically, the above arrangement allows the gate line to appear on the material-formed transition structure 32 in the transition feed channel 31, and not on the design face 11 of the plate-like design member.
Optionally, the gate 34 has a first preset distance from the appearance surface 11, and the first preset distance is greater than or equal to 10mm. Thus, the arrangement ensures that no glue inlet lines are formed on the appearance surface 11 to cause appearance defects, and the appearance attractiveness of the appearance part is improved.
In other embodiments not shown in the drawings, the feed channel 30 comprises a gate 34, the gate 34 communicating with the cavity of the mold, and the feed forming zone being arranged in correspondence with the gate 34. Wherein the gate 34 is a fan gate.
As shown in fig. 1 to 5, the feed channel 30 further includes a buffer flow passage 33, and the buffer flow passage 33 communicates with the gate 34 through the transition feed channel 31. The transition feed channel 31 includes a sub-flow passage 311 and a transition flow passage 312. The two ends of the buffer flow passage 33 are respectively communicated with the sub flow passage 311 and the cavity. The two ends of the transition flow passage 312 are respectively communicated with the sub flow passage 311 and the gate 34. Wherein, there is one transition feed channel 31 and one gate 34; alternatively, the plurality of transition feed channels 31 are provided, the plurality of transition feed channels 31 are arranged at intervals around the circumference of the buffer runner 33, the plurality of gates 34 are provided, and the plurality of gates 34 and the plurality of transition feed channels 31 are arranged in one-to-one correspondence. Thus, on one hand, the arrangement ensures that the materials in the molten state can enter the sprue 34 through the buffer flow channel 33, the sub flow channel 311 and the transition flow channel 312 for injection molding; on the other hand, the number of the transition feeding channels 31 and the number of the gates 34 are more flexibly selected, so that different use requirements and working conditions are met, and the processing flexibility of workers is improved.
In the present embodiment, there are two transition feed channels 31, two transition feed channels 31 are arranged at intervals around the buffer flow channel 33 in the circumferential direction, there are two gates 34, and the two gates 34 are arranged in one-to-one correspondence with the two transition feed channels 31.
Optionally, the height of the transition flow passage 312 is greater than or equal to 6mm; and/or the width of the transition flow channel 312 is greater than or equal to 8mm; and/or the thickness D of the transition flow passage 312 and the main wall thickness D of the plate-shaped appearance part satisfy the following conditions: d is more than or equal to 0.4D and less than or equal to 0.8D. Thus, the selection of the above dimensions enables the transition flow channel 312 to buffer the material in the molten state well, and ensures that the transition flow channel 312 does not shrink in the appearance surface area. The cushioning effect is to prevent the flow mark texture from diverging from a point at the gate 34, but diverging from a wider range after the transition, ensuring the aesthetic appearance of the texture.
As shown in fig. 2, the sub-flow passage 311 includes a first flow passage 3111 and a second flow passage 3112 which are communicated with each other, and the first flow passage 3111 and the second flow passage 3112 are disposed at an angle. Both ends of the first passage 3111 communicate with the buffer passage 33 and the second passage 3112, respectively, and the gate 34 communicates with the middle of the second passage 3112. Thus, the length of the sub-runner 311 is increased by the arrangement, the flow path of the molten material in the sub-runner 311 is increased, and the injection molding efficiency is improved.
As shown in fig. 1 and 2, the number of the sub-runners 311 is two, and the number of the gates 34 is two; the two oppositely disposed sides of the plate-like appearance part are bent toward each other to form the first arc-shaped plate 13 and the second arc-shaped plate 14, and two gates 34 are provided on the first arc-shaped plate 13 and the second arc-shaped plate 14, respectively. The first flow channel 3111 of the at least one sub-flow channel 311 is bent toward the through hole, and the degree of bending of the second flow channel 3112 of the at least one sub-flow channel 311 coincides with the degree of bending of the corresponding first arc-shaped plate 13 or second arc-shaped plate 14. Thus, the length of the sub-runner 311 is further increased by the arrangement, so that the molten material can be filled in the mold for injection molding, and the processing quality of the plate-shaped appearance part is improved.
Optionally, the transitional feeding channel 31 is multiple, and the multiple transitional feeding channels 31 are uniformly distributed around the circumference of the buffer flow channel 33. Thus, the above arrangement improves the uniformity of injection molding of the mold to the plate-like exterior member, and reduces appearance defects such as flow marks, weld marks, gate marks, and the like on the exterior surface 11.
Optionally, the plate-like appearance member has a length of less than 300mm and a width of less than 300mm.
The application also provides a household appliance (not shown) comprising a plate-shaped appearance part, wherein the appearance surface 11 of the plate-shaped appearance part forms at least part of the appearance surface of the household appliance, and the appearance part is the plate-shaped appearance part.
