Aluminum casting mold

Abstract

The invention relates to the technical field of forming cast aluminum rotors, and particularly relates to an aluminum casting mold. The aluminum casting mold comprises a middle mold, a lower mold, anupper mold, a pressing plate and a positioning sleeve, wherein the lower mold is arranged at the bottom end of the middle mold, the upper mold is arranged in the middle mold, the pressing plate coversthe top end of the middle mold, and the positioning sleeve is arranged between the pressing plate and the upper mold; the two ends of the positioning sleeve abut against the pressing plate and the upper mold respectively, the lower mold, the middle mold and the upper mold surround to form an aluminum casting space, the lower mold is provided with an aluminum injection hole communicating with thealuminum casting space, the upper mold is provided with a first pass shaft hole, the pressing plate is provided with a second pass shaft hole, the first pass shaft hole is in communication with the second pass shaft hole through the positioning sleeve, and the first pass shaft hole, the positioning sleeve and the second pass shaft hole are coaxially arranged. According to the aluminum casting mold, the cast aluminum rotor with different specifications can be produced only by replacing the positioning sleeve, the universality is good, the application range is wide, the manufacturing and using cost of the aluminum casting mold is reduced, the cycle of manufacturing the aluminum casting mold is shortened, and the difficulty of manufacturing the aluminum casting mold is reduced.

Description

technical field [0001] The invention relates to the technical field of molded cast aluminum rotors, in particular to a cast aluminum mold. Background technique [0002] As we all know, the existing motor rotor aluminum casting process is completed by a cast aluminum mold, and the cast aluminum mold is composed of a cast aluminum upper mold, a cast aluminum middle mold and a cast aluminum lower mold. There are many specifications of the same outer diameter and different lengths in the motor rotor. Therefore, when producing rotors with the same outer diameter but different lengths, many sets of cast aluminum middle molds with different specifications and lengths are required to produce rotors of different lengths. Since the manufacturing material of the cast aluminum middle mold is made of ductile iron, the material is very expensive and the manufacturing cost is high, and the production of the rotor requires high precision for the cast aluminum middle mold, which makes it dif...

AI Technical Summary

Problems solved by technology

Since the manufacturing material of the cast aluminum middle mold is made of ductile iron, the material is very expensive and the manufacturing cost is high, and the production of the rotor requires high precision for the cast aluminum middle mold, which makes it difficult to manufacture the cast aluminum middle mold and the manufacturing cycle is long. It reduces the efficiency of manufacturing cast aluminum molds and producing rotors, which greatly affects the production efficiency of enterprises

In addition, the volume of the cast aluminum middle mold is large, and the space occupied by the cast aluminum middle mold is large, so it is difficult to store the cast aluminum middle mold
