Innovative report on deep hole drilling inclined hole processing technology for precision mold manufacturing

date：2023/08/10

1. The industry's first initiative to reduce processing costs:
 
current technology:
 
In the precision mold manufacturing industry, the production of a single single fixture or the processing of the inclined hole platform on the horizontal machine tool is first processed, which is costly and inefficient.
 
Innovative Technology:
 
Adopting movable and sealing oil front end, single diameter specification corresponds to “arbitrary” angle, direct processing on inclined surface, low cost and high efficiency.

2. Flexible, simple and adaptable:
 
current technology:
 
Precision mold processing Each diameter specification corresponds to a different angle oblique hole to correspond to a special fixture.
 
For precision mold processing, if the diameter is φ4～φ24, there are 18 models. The commonly used angle is about 1°~65°, about 65 kinds, and 1170 special fixtures are needed.
 
Innovative Technology:
 
The main structure of the precision mold processing fixture only needs one type, and the drills of different diameters only need one corresponding guide core to process the inclined hole from 1° to 65°.
 
A. After the improvement, it can completely realize the processing independently, and reduce the processing cost of the outward processing oblique water hole:
 
The cost of external processing is 120 yuan/bar within 200mm and 240 yuan/piece within 400mm. The processing in the factory by fixture is only 20 yuan/bar within 200mm, 40 yuan/bar within 400, and the processing cost per piece is reduced by 83%. .
 
B, bottom shell, automobile mold, electric equipment and other mold parts have inclined water holes, about 550 pieces of inclined hole parts are drilled according to the year, and the annual reduction is about 350,000 yuan/year.
