Problems solved by technology

[0010] The purpose of the present invention is to solve the problem of poor straightness of the rotor iron core in the existing motor centrifugal casting rotor technology, and to provide a Huff locking device applied to the centrifugal casting mold of the motor. A Hough structure holds the rotor iron core tightly to correct its straightness; then it continues to hold tightly during the solidification of the molten aluminum to maintain the straightness of the inner hole and outer diameter of the rotor, and is not released until the casting is completed

Embodiment Construction

[0029] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0030] Such as figure 1 , figure 2 with image 3 As shown, the mold in the particular embodiment is composed of a lower mold part and an upper mold part, as previously described, the upper mold part and the lower mold part are coaxially displaced in the open and closed mold positions. The lower mold part includes a rotational mount 19 which is caused to rotate about its central axis as the molten metal is poured into the closed mould. The rotating fixed seat 19 has a plurality of upper peripheral axial guide pillars 7, and the lower part of the guide pillars is firmly fixed on the rotating fixed seat 19 by a process, such as inserted into the rotating fixed seat guide post hole 17, and locked with a nut 5. Shown in the figure are two axial guide pillars 7, actually there are three such guide pillars, which are uniformly distributed at interv...

Abstract

The invention relates to the field of motor casting, and aims to provide a half locking device applied to a centrifugal casting mould of a motor. The half locking device is arranged in a lower casting mould cavity, and consists of a half fixing jacket with an inclined inner circle, and a half capable of being put into the inclined inner circle; the half comprises more than two half sliding blocks to together form an inverted hollow circular truncated cone; and the inner circle of the circular truncated cone is matched with the excircle of a motor rotor pack component required to be cast. When the device is adopted for half locking casting, the linearity of the outer diameter and inner diameter of the produced motor rotor is kept unchanged basically, and the further in-hole finish machining with high difficulty is avoided.

Description

technical field [0001] The invention relates to the field of motor casting, in particular, it is a Huff locking device applied to the centrifugal casting mold of the motor, especially suitable for those small motor rotors produced by the cutting-free method, such as being suitable for the hermetic compressor of the refrigeration system small motor rotors. Background technique [0002] The present invention comes from the previous centrifuge method perfusion technology with rotor aluminum cage. This technology is composed of an assembly composed of the same annular steel sheet structure, providing openings arranged longitudinally with the openings of other component laminations to determine a complex axial channel; interconnected with the outside of the component laminations, arranged along a circle , spaced angularly from each other. They are concentric with the longitudinal axis of the lamination pack, but, for the trailing transverse faces, radially spaced towards the la...
