Problems solved by technology

Although the design and operability of the above-mentioned processes are good, they all have cumbersome procedures, low work efficiency, and the connection parts are prone to defects and leaks, forming weak links, and the appearance is poor and the quality is unstable. Less than the strength requirements of high-speed operation, the production method of FRP hand-lay-up impellers cannot make a qualitative improvement in quality, thus restricting the progress and development of anti-corrosion fan time wheels
At present, there is no plastic-steel fan and impeller integrated molding process and its special mold that can overcome the above-mentioned shortcomings.

Embodiment Construction

[0025] 1. Description of the centrifuge impeller process embodiment:

[0026] 1. Material selection: Bisphenol A structure and vinyl ester resin materials with excellent corrosion resistance and corrosion-resistant glass fiber reinforced materials are used as base materials.

[0027] 2. Ingredients: ingredients: 30-40% resin, 30-50% reinforced glass fiber, the rest are auxiliary materials such as plasticizers and fillers: use a kneader or a sheet machine to mix until it becomes agglomerated DMC or SMC for later use.

[0028] 3. Skeleton production: Weld several stamped special-shaped parts or centrifuge impeller-shaped metal skeleton (the rear disc and impeller are integrated, the front disc can be manufactured separately, and the two are pre-embedded with connecting screws and nuts, and then pressed separately. assembly).

[0029] 4. Making prototype intermediates. Attach the above-mentioned group or sheet to the metal skeleton, wrap it with a certain thickness, and wrap it...

Abstract

The invention relates to a method for producing molded plastic steel fan blade wheel, and relative special mould, wherein it mainly comprises: producing integrated skeleton, producing base middle element, molding, and demoulding; the special mould comprises the upper and lower moulds and the overflow structure. The invention has the advantages that: it has high producing efficiency, high quality and high accuracy; the inventive blade wheel has light weight, high strength, high accuracy and stable operation.

Description

technical field [0001] The invention relates to the technical field of pressure forming or connection of plastics. Specifically, the invention relates to a production process of a molded plastic steel fan impeller and a special mold thereof. Background technique [0002] Ordinary metal fan impellers and anti-corrosion FRP fan middle wheels are currently manufactured by welding or bonding of components. Although the design and operability of the above-mentioned processes are good, they all have cumbersome procedures, low work efficiency, and the connection parts are prone to defects and leaks, forming weak links, and the appearance is poor and the quality is unstable. Less than the strength requirements of high-speed operation, the manufacturing method of FRP hand-laid impellers cannot qualitatively improve the quality, thus restricting the progress and development of anti-corrosion fan time wheels. And there is no plastic-steel blower fan and impeller integrated molding pr...
