Problems solved by technology

The impeller formed by the above method uses the inner disk, the blade, and the outer disk because it is not integrally formed, but purely depends on the interlayer shear strength existing between the three, and its bonding surface is the weak point, so The impeller has poor integrity, low connection strength, easy to disengage and damage during operation, and has the disadvantages of low geometric accuracy, resulting in low fan efficiency

Embodiment Construction

[0010] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0011] Figure 1-2 Shows the structure of the blade mold of the mold in the present invention, Figure 3-4 The structure of the outer wheel mold is shown.

[0012] Such as Figure 1-4 As shown, the mold in the present invention includes an outer disk mold, a blade mold and an inner disk mold (not shown).

[0013] The blade mold is a cylinder, which is divided into two parts, an upper part and a lower part; the upper part is a recess 4 formed by the ring-shaped part 1 and recessed into the blade mold, and the recess 4 is used to place The inner disc mold; the lower part is a solid cylinder with a pre-formed blade cavity 2, preferably, there are 10 blade cavities; from the center of the top of the blade cavity 2 to the A shaft portion 3 protrudes from the inside of the concave portion 4 , preferably, the shaft portion 3 protrudes outside t...

Abstract

The invention relates to an integrated mould of a fan impeller. The integrated mould comprises an outer wheel disc mould, a blade mould and an inner wheel disc mould. The integrated mould is characterized in that the blade mould is divided into an upper part and a lower part; the upper part forms a concave part (4) which is recessed to the inside of the blade mould; the concave part (4) is used for placing the inner wheel disc mould; and the lower part is provided with a preformed blade mold cavity (2). As the blade is directly formed on an inner wheel disc and an outer wheel disc of the impeller by the blade mold cavity, the fan impeller manufactured by the mould has the characteristics of high geometrical precision, high integration and corrosive resistance.

Description

technical field [0001] The invention relates to an integral molding die, in particular to an integral molding die of a fan impeller. Background technique [0002] The impeller is the main part of the centrifugal fan and consists of an inner disc, blades and an outer disc. In the prior art, the manufacturing method of the centrifugal fan impeller made of composite material is to process the inner disc, the blade and the outer disc separately, and then form the three into a whole by welding, bonding, riveting, etc. Appropriate reinforcement shall be carried out at the joints. The impeller formed by the above method uses the inner disk, the blade, and the outer disk because it is not integrally formed, but purely depends on the interlayer shear strength existing between the three, and its bonding surface is the weak point, so The impeller has poor integrity, low connection strength, is easy to disengage and be damaged during operation, and has the disadvantages of low geometr...
