High-pressure water pump impeller molding and processing method

Abstract

The invention relates to a high-pressure water pump impeller molding and processing method which uses a high-pressure water pump impeller molding device. The high-pressure water pump impeller moldingdevice comprises a mounting bottom plate, a supporting column, a positioning mechanism and a cleaning mechanism. The high-pressure water pump impeller molding and processing method provided by the invention can solve the problems that in the high-pressure water pump accessory molding process, an upper box and a lower box which are used during casting molding need to be manually aligned, then a clamping tool is used for clamping and positioning the upper box and the lower box, during the period, stable and effective clamping and positioning operation is difficult to conduct due to the size difference of the casting box, residual casting liquid in the casting openings is difficult to completely remove manually due to the fact that the inclination angles and the diameters of casting openingsare not completely the same, the depth influence of the casting openings can influence cleaning operation to a certain extent, whether the inner walls of the casting openings are completely cleaned ornot is difficult to judge manually, the working efficiency of high-pressure water pump accessory molding operation is reduced, and the like.

Description

technical field [0001] The invention relates to the technical field of water pump impeller processing, in particular to a high-pressure water pump impeller molding processing method. Background technique [0002] The impeller of the high pressure water pump is made of cast iron. The blades on the impeller of the high-pressure water pump play a major role again. The shape and size of the impeller of the high-pressure water pump are closely related to the performance of the water pump. The semi-open and open impellers in the blade-type impeller are easy to cast and easy to maintain and clean up impurities that are blocked during the transportation process. . [0003] When processing the impeller of the high-pressure water pump, due to the complex structure and shape of the impeller, it is usually necessary to form the impeller of the high-pressure water pump by casting.

AI Technical Summary

Problems solved by technology

[0003] When processing the impeller of the high-pressure water pump, due to the complex structure and shape of the impeller, it is usually necessary to form the impeller of the high-pressure water pump by casting. However, the following problems often exist in the molding process of traditional high-pressure water pump accessories: a. During the molding process of high-pressure water pump accessories, the upper box and the lower box used for casting are often manually The box is manually aligned, and then clamped and positioned with a clamping tool. During this period, due to the large size and heavy weight of the casting box, it is difficult to perform stable and effective clamping and positioning operations. The labor intensity is high, which reduces the working efficiency of the processing work, and the poor sealing performance will lead to an increase in the defective rate of the finished product. b. During the molding operation of the traditional high-pressure water pump accessories, after the casting is completed, due to the different inclination angle and diameter of the casting port In the same way, it is difficult to completely remove the residual casting liquid in the casting mouth by manual work. Usually, the number of impellers that need to be processed is large, and the casting mouth needs to be cleaned and polished many times, and the depth of the casting mouth will also affect the cleaning. The operation has a certain degree of impact, and it is difficult to manually judge whether the inner wall of the casting port is completely cleaned, which reduces the work efficiency of the high-pressure water pump accessories molding operation
