Groove insulation paper mold

Abstract

The invention discloses a groove insulation paper mold. The groove insulation paper mold comprises an upper mold and a lower mold, the upper mold comprises an upper mold body, and the lower mold comprises a lower mold body; the upper surface of the lower mold body is provided with a first groove of which the two ends are provided with openings, a first pressing rod capable of vertically moving inthe groove depth direction of the first groove is arranged in the first groove, and the two ends of the first pressing rod stretch out of the two ends of the first groove and are connected with elastic mechanisms; and a second pressing rod is arranged on the lower surface of the upper mold body, and the second pressing rod is located over the first pressing rod and can vertically move in the groove depth direction of the first groove in the working process. According to the groove insulation paper mold, insulation paper is put between the second pressing rod and the first pressing rod to be pressed and molded in the first groove, the elastic mechanisms reset and drive the first pressing rod and the molded insulation paper to move upwards, and automatic demolding of the insulation paper iscompleted.

Description

technical field [0001] The invention belongs to an insulating paper forming die, in particular to an insulating paper forming die used for motor slots. Background technique [0002] In the stator slot of the motor, there are insulating paper in the slot and insulating paper in the slot. The insulating paper in the slot and the insulating paper in the slot together form a relatively closed space to play an insulating role and prevent the stator winding from contacting the stator core. The insulation film on the surface of the stator winding can be damaged by contact with the stator, so that the stator winding can be effectively protected from damage. [0003] Because the insulating paper has a certain degree of elasticity, if the untreated insulating paper is directly placed in the slot, the insulating paper cannot be closely attached to the slot shoulder, and it is prone to displacement, resulting in poor insulation or motor burnout, and in severe cases, it will cause electr...

Problems solved by technology

[0003] Because the insulating paper has a certain degree of elasticity, if the untreated insulating paper is directly placed in the slot, the insulating paper cannot be closely attached to the slot shoulder, and it is prone to displacement, resulting in poor insulation or motor burnout, and in severe cases, it will cause electric leakage, etc. security incident

However, the existing notch insulation molds generally use plate bending molds, which are relatively large, complex in design, high in production cost, and require manual demoulding after stamping is completed, resulting in low efficiency.
