Together, and between tabletting and middle mould there are gap, (gap is because glass insulator manufactured size is larger, to compensate softening
When the volume that reduces), then will bending pin by bend pin channel is fitted into mould, and the top for bending pin is located at and bends
In pin channel；Upper mold is covered, mold is integrally put into later on the mesh belt of sintering furnace, is sintered, in sintering high temperature,
Glass insulator starts to soften, simultaneously because the weight of upper mold itself, bending pin briquetting will be bent at the top of pin to be drawn from bending
Foot gradually extrudes in channel, and glass insulator has also filled up corresponding region on metal base plate when extruding completely, curved at this time
The position and direction for rolling over pin are held essentially constant in cooling, to ensure that the concentricity of bending pin.
Compared with prior art, the utility model has the following characteristics that
1) by middle mould, tabletting, the cooperation of upper mold, bending pin is gradually pressed on metal base plate in advance during the sintering process
If at position, and guarantee bend pin concentricity, substantially increase the quality of product, make yield rate can achieve 95% with
On；
2) requirement to glass insulator machining accuracy is reduced, processing efficiency is improved, saves cost.
