Air deflector, injection mold and molding method

Abstract

The invention provides an air guide plate, an injection mold and a molding method. The method comprises the following steps: a molded air guide plate insert is positioned in a molding cavity of the injection mold through a magnetic sucking piece; and a molten air guide plate outer-layer material is injected in the molding cavity, so that the outer-layer material wraps the air guide plate insert to form the air guide plate. The air guide plate adopts a sandwich layer embedding form to replace a double-layer structure form of a conventional aluminum alloy air guide plate, can only occupy less internal space of the air guide plate under the condition of guaranteeing strength and deformation resistance of the air guide plate, reduces the whole thickness of the air guide plate, and reduces the shape volume of the air guide plate.

Description

Technical field [0001] The invention relates to the technical field of air-conditioning wind deflectors, in particular to a wind deflector, an injection mold and a molding method. Background technique [0002] Most of the current air-conditioning products wind deflectors are directly injection molded from plastic parts. Due to the limitation of the injection molding process and the thermal deformation of the wind deflectors, the wind deflectors cannot meet the requirements of high strength and high straightness. There is a flash seam problem in the matching parts of the shell, resulting in a poor appearance of the air conditioner and a poor user experience. [0003] In the prior art, in order to control the deformation of the existing air-conditioning products, most of the existing air-conditioning products adopt a double-layer structure assembled by aluminum alloy and plastic, such as an outer aluminum alloy inner layer plastic or an inner aluminum alloy outer layer plastic.

Problems solved by technology

[0002] Most of the air deflectors of current air-conditioning products are directly injection molded by plastic parts. Due to the limitation of the injection molding process and the thermal deformation of the air deflectors, the air deflectors cannot meet the requirements of high strength and high straightness, resulting in that when the air deflectors are closed, the air deflectors will not meet the hood There is a problem of flash seams in the joints such as the shell, resulting in a poor appearance of the air conditioner and a poor user experience

[0003] In the prior art, in order to control the deformation of the existing air-conditioning products, most of the air deflectors adopt a double-layer structure assembled by aluminum alloy and plastic, such as the outer layer of aluminum alloy and the inner layer of plastic or the inner layer of aluminum alloy and the outer layer of plastic. Due to the limitations of the properties of the aluminum alloy material and the forming method, the thickness of the wind deflector made of the aluminum alloy material is thicker and the weight is heavier, which is not conducive to the use of related air-conditioning products.
