Processing die of stirrer with aeration function

Abstract

The invention discloses a processing die of a stirrer with an aeration function, and belongs to the technical field of environmental protection mechanical equipment. The processing die comprises an upper die and a lower die, wherein the upper die is provided with a guide post hole and a die core; the lower die is provided with a guide post and a die cavity; the guide post hole in the upper die issleeved into the guide post on the lower die; the upper die and the lower die are closed by applying external force; a casting material is poured into a pouring hole and is injected into the die cavity through a pouring channel; and after cooling, the die is opened to take out a part. According to the processing die of the stirrer with the aeration function, parting is performed from the central position of an air nozzle, and a structure of one die and two cavities is adopted, so that the structure is novel, and later demolding is facilitated; and the die is finished in the same clamping process in the preparation process, so that the form and position errors of the two cavities are small, the part which is formed by pouring can be ensured to have high assembly accuracy, the processing problem of the stirrer can be solved, the processing die is convenient to operate, and the manufacturing efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection machinery and equipment, and relates to a processing mold, in particular to a processing mold with an aeration function agitator. Background technique [0002] In the treatment of waste water and waste liquid, because of the need to increase the oxygen content in waste water and waste liquid, stirring devices are often used. Most of the currently used stirring devices use the combination of axial flow pump and impeller, which has high power consumption, high noise and high maintenance cost. , based on the deficiencies of the existing stirring device, a stirring device with aeration function is designed. The device adopts the design of no impeller. It is difficult to process the device, and it is almost impossible to process it with traditional machining methods. If the conventional mold design is adopted, the Venturi jet port cannot be core-pulled and demolded smoothly. Based on t...

[0002] In the treatment of waste water and waste liquid, because of the need to increase the oxygen content in waste water and waste liquid, stirring devices are often used. Most of the currently used stirring devices use the combination of axial flow pump and impeller, which has high power consumption, high noise and high maintenance cost. , based on the deficiencies of the existing stirring device, a stirring device with aeration function is designed. The device adopts the design of no impeller. It is difficult to process the device, and it is almost impossible to process it with traditional machining methods. If the conventional mold design is adopted, the Venturi jet port cannot be core-pulled and demolded smoothly. Based on the above difficulties, it is necessary to design a special processing mold to solve the problem. Processing Problems of Complicated Structure of Mixer with Aeration Function
