Problems solved by technology
[0004] 1. When the rotating brush cleans the impeller, the impeller cannot be rotated, so the impeller is not cleaned thoroughly, and the spiral blades on the impeller will hinder the cleaning action of the rotating brush;
[0005] 2. After the impeller is cleaned, it is necessary to manually shake off the debris remaining in the impeller blades, which increases the amount of manual labor

Embodiment Construction
[0038]The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0039] Such as Figure 1 to Figure 5 Shown, a kind of water pump impeller manufacturing processing method comprises the following steps:
[0040] S1. Molding sand preparation: select one or more of quartz sand, magnesia, limestone sand and resin sand and put them into the sand mixer for full mixing;
[0041] S2. Molding sand molding: Put the molding sand mixed in step S1 into the upper flask and the lower flask respectively, and carry out molding processing on the molding sand in the upper flask and the lower flask through the shape of the impeller;
[0042] S3. Sand box mould-closing: Dry the molding sand in the upper sand box and the lower sand box in step S2 with a dryer to make the molding sand in the sand box more compact. Check the dried sand ...

The invention relates to a water pump impeller manufacturing method. The water pump impeller manufacturing method comprises the steps of (S1) molding sand preparation, (S2) sand molding, (S3) sand boxmold closing, (S4) sand box casting, (S5) impeller casting shakeout, (S6) impeller casting cleaning and (S7) impeller surface treatment. In the step (S6), impeller castings with casting port projections cut off in the step (S5) are placed on a locking mechanism for locking, through control of rotation of a rotating belt mounted on a base plate, the impeller castings can be driven to convey, and acleaning mechanism can thoroughly remove sand grains attached on the side surfaces of the impeller castings during conveying of the impeller casting. The water pump impeller manufacturing method cansolve the problems in a traditional impeller cleaning mode: impellers cannot be rotated during cleaning of the impellers by a rotating brush, so that the cleaning of the impellers is not thorough, andspiral blades on the impellers can stop the cleaning action of the rotating brush; and after cleaning of the impellers, impurities remaining in the blades of the impellers are manually shaken off, sothat the labor amount is increased.
Description
technical field [0001] The invention relates to the technical field of casting and processing, in particular to a manufacturing and processing method of a water pump impeller. Background technique [0002] The water pump impeller is the core component of the water pump, which mainly affects the working efficiency of the water pump. At present, the water pump impeller mainly has the following three forms, namely closed impeller, semi-open impeller, and open impeller. The semi-open impeller is less difficult to manufacture and costs less. Low, and strong adaptability, in recent years, the application of centrifugal pumps in refining and chemical industry has gradually increased; the semi-open impeller is a disc-shaped structure with a round hole in the middle, and the upper side of the impeller is evenly equipped with spiral blades. [0003] The processing of the impeller is mainly carried out by casting. After the impeller is cast, it needs to be cleaned by falling sand, so t...
