Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a high-speed fan air duct demoulding structure. Background Art

[0002] like Figure 1 and Figure 2 As shown, the existing product air duct adopts an involute air duct mold body 4, which is an involute mold. However, this structure cannot be made into a rotating mold and can only be directly ejected and inserted into the mold. The injection molded product made from this product structure has clamping lines on the fan blades, which affects the air outlet efficiency of the air duct. Summary of the invention

[0003] In view of the problems existing in the prior art, the utility model aims to provide a high-speed fan air duct demoulding structure.

[0004] To solve the above problems, the utility model adopts the following technical solutions.

[0005] A high-speed fan air duct demoulding structure comprises an outer mold and an inner mold, wherein a spiral air duct mold body is arranged between the outer mold and the inner mold.

[0006] Beneficial effects of the utility model

[0007] Compared with the prior art, the advantages of the present invention are:

[0008] The utility model changes the involute line into a spiral line, and the rear mold of the improved mold is rotated to remove the mold, and there is no clamping line between the fan blades, thereby improving the air outlet efficiency of the air duct. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a structural schematic diagram of the prior art.

[0010] Figure 2 It is a structural schematic diagram of the prior art from another perspective.

[0011] Figure 3 It is a structural schematic diagram of the utility model.

[0012] Figure 4 It is a structural schematic diagram of the bottom of the utility model. DETAILED DESCRIPTION

[0013] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0014] See also Figure 3 to Figure 4 A high-speed fan duct demoulding structure includes an outer mold 1 and an inner mold 2, wherein a spiral air duct mold body 3 is arranged between the outer mold 1 and the inner mold 2. After the improvement, the rear mold of the rear mold is rotated to demould, and there is no clamping line between the fan blades, thereby improving the air outlet efficiency of the duct.

[0015] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.

Claims
