Embodiment 1

[0030] Such as figure 1 As shown, the present embodiment proposes a lower mold for forming an ultra-thin fan blade of a cooling fan, including: a forming part 71, a base 72, a first elastic member 73, an ejection part 74 and a driving mechanism, and the base 72 is placed on the working On the plane, a molding part 71 is installed above the base 72, and the molding part 71 is provided with an injection cavity, and the injection cavity runs through the molding part 71, and the molding part 71 can move relative to the base 72, and a first elastic member is installed between the molding part 71 and the base 72 73. An ejection portion 74 is provided below the molding portion 71. The ejection portion 74, the base 72 or the molding portion 71 form a support surface that supports the bottom surface of the blade in the cooling fan, and the ejection portion 74 or the base 72 forms a The first contact surface, the first contact surface is used to contact with one side of the blade, the s...

Embodiment 2

[0037] The present invention also proposes a molding die for an ultra-thin fan blade of a cooling fan, comprising: an upper die and a lower die for forming the ultra-thin fan blade of a cooling fan as described above.

[0038] Such as figure 2 as well as image 3 As shown, the upper mold includes: mold body 1, nozzle 2, guide channel 3, glue injection plate 4 and heating device 5, nozzle 2 is installed on the top of mold body 1, and nozzle 2 is used to communicate with the nozzle of the glue injection machine , the middle part of the mold body 1 is equipped with a guide channel 3, the middle part of the mold body 1 is equipped with a glue injection plate 4, and a number of glue injection holes are opened on the glue injection plate 4; the heating device 5 includes: a heating ring 51 and an electrical connector 52, a heating ring 51 surrounds the guide channel 3, and an electrical connector 52 is installed on the mold body 1, and the electrical connector 52 is used to electri...

Embodiment 3

[0046] The present invention proposes a method for manufacturing an ultra-thin fan blade of a cooling fan, comprising the following steps:

[0047] S1. The lifting device drives the lower mold down to close the molding cavity, the first elastic member 73 is deformed, and the supporting surface and the first contact surface surround the inner wall of the injection cavity to form a molding cavity;

[0048] S2. Pour hot melt material into the forming cavity of the forming mold of the ultra-thin fan blade of the cooling fan;

[0049] S3, the hot melt material is cooled, and a cooling fan is formed in the molding cavity;

[0050] S4. When the mold is opened, the lifting device in the injection molding machine drives the upper mold to move, and the molding cavity is opened. Under the action of the elastic force of the first elastic member, the molding part rises, and the blade of the cooling fan is separated from the first contact surface or the inner wall of the injection cavity; ...

Abstract

The invention provides a lower forming die, a forming die and a manufacturing method of an ultra-thin fan blade of a cooling fan. The lower forming die of the ultra-thin fan blade of the cooling fan comprises a forming part, a base, a first elastic piece, an ejection part and a driving mechanism, wherein the base is placed on a working plane; the forming part is arranged above the base; an injection cavity is formed in the forming part; the injection cavity penetrates through the forming part; the forming part can move relative to the base; the first elastic piece is arranged between the forming part and the base; the ejection part is arranged below the forming part; the ejection part, the base or the forming part forms a supporting surface for supporting the bottom surface of the blade inthe cooling fan; the ejection part or the base forms a first contact surface located in the forming cavity; and the first contact surface is used for being in contact with one side surface of the blade. According to the lower forming die of the ultra-thin fan blade of the cooling fan and the die comprising the lower forming die, the problem that in the prior art, due to the fact that a one-time demolding mode is adopted, the two sides of the blade have adhesive force to limit demolding, and the blade is deformed and damaged is solved.

Description

technical field [0001] The invention relates to a heat dissipation fan, in particular to a forming lower mold, a forming mold and a manufacturing method of an ultra-thin fan blade of a heat dissipation fan. Background technique [0002] The cooling fan includes: a mounting ring, a reinforcing ring and several blades. All the blades are evenly distributed on the mounting ring. The roots of all blades are fixed to the mounting ring. The tips of all blades are fixed to the reinforcing ring. above. Due to different requirements, the thickness of the blade needs to be less than 0.2mm. The blade is generally formed in the lower mold. There is adhesion between both sides of the blade and the lower mold, which causes the blade to be easily deformed and damaged during the demoulding process. The product cannot meet the quality requirements and wastes materials. Contents of the invention [0003] The present invention provides a forming lower mold, a forming mold and a manufacturi...
