Abstract

The invention discloses a processing method of internal creepage distance ribs of an embedded pole component provided with an insulating sheath made of thermoplastic material. The bottom of the embedded pole component is square; the internal creepage distance ribs are arranged on at least one surface of the bottom of the embedded pole component; concave lines are formed in at least one surface of one outer side sliding block; a center sliding block is connected with a first stretching driving device; the outer side sliding block with the concave lines is connected with a demoulding driving device; the outer side sliding blocks are integrally connected with a second stretching driving device; before injection molding, a sliding block component is put at the bottom of the embedded pole component; and after the injection moulding, the first stretching driving device is controlled to pull out the center sliding block, then the demoulding driving device is controlled to separate the moulded internal creepage distance ribs from the outer side sliding blocks, finally the second stretching driving device is controlled to pull the integral outer side sliding blocks out of the bottom of the embedded pole component. The invention also provides a processing device of the internal creepage distance ribs of the embedded pole component provided with the insulating sheath made of thermoplastic material. According to the processing method and the processing device, the assembling processes are simplified, the radiating effect is effectively ensured, and high temperature rise is avoided.

Description

technical field [0001] The invention relates to power switching equipment, in particular to a processing method and device for embedded pole parts. Background technique [0002] Due to the limitation of the distance from the lower conductive end of the embedded pole part (also called solid-sealed pole) with insulating sheath made of thermoplastic material to the bottom mounting surface, the surface distance inside the insulating material, that is, the creepage distance, is relatively small. In order to increase the creepage distance, the current solution and main problem is to add an additional sealing cover made of insulating material to the bottom cavity of the solid-sealed pole to completely isolate the interior of the pole cavity from the metal frame of the circuit breaker. The advantage of this solution is that the inner side of the insulating sheath of the solid-sealed pole has no ribs perpendicular to the axis, that is, the surface of the mold slider is straight, whic...
