Description

Technical Field

[0001] The utility model belongs to the technical field of motor assembly and relates to a commutator mold demoulding device. Background Art

[0002] The commutator, also known as the "rectifier", is an important component on the armature of DC motors and AC commutator motors. It is composed of many copper sheets separated by mica sheets and is cylindrical or disc-shaped. Each copper sheet is connected to several armature winding elements. When the armature rotates, the copper sheets successively contact the fixed brushes. In DC motors, the AC current in the armature winding is converted into DC current between the brushes through the brushes and the commutator. In AC commutator motors, the frequency of the AC current between the brushes is made to meet the working requirements. The commutator is often produced by extrusion molding and demolding.

[0003] Traditional commutator demoulding The demoulding of commutator molds is mostly done manually or by semi-automatic demoulding devices. Manual demoulding is labor-intensive and has low work efficiency. Semi-automatic demoulding devices can only demould the mold, have a single function, poor practicality, and do not have a feeding function.

[0004] After searching, it was found that a Chinese patent document discloses a commutator mold demolding device [Application No.: 202120650436.0; Publication No.: CN216267085U]. This device includes a base and a top plate, with a first plate, a second plate, a third plate, a fourth plate, a fifth plate, and a sixth plate arranged between the base and the top plate. The four corners of the top plate are penetrated by a fixing rod passing through the third plate, the fifth plate, and the base, and a hydraulic cylinder is provided on the top plate. The driving rod of the hydraulic cylinder passes through the top plate and is connected to the first plate. The first plate, the second plate, the fourth plate, and the sixth plate can move up and down on the fixing rod. The second plate and the fourth plate are both provided with a first holder for placing the commutator mold, and the bottom surface of the base is provided with a second holder for placing the commutator mold. The commutator mold includes an upper plate, a middle plate, and a lower plate.

[0005] Although the demoulding device disclosed in the patent can demould the commutator mold, it can only demould the mold, has a single function, poor practicality, and does not have a material feeding function.

[0006] Based on this, we proposed a commutator mold demolding device, which can quickly perform extrusion shaping or mold demolding, improve the operating efficiency of the device, and can quickly and conveniently switch between extrusion shaping and mold demolding, reducing costs, improving the practicality of the device, and having the output collection of finished commutators, reducing the labor intensity of staff, and improving the degree of automation of the device.
