Description

Technical Field

[0001] The invention relates to a method for manufacturing core parts of bottle embryo conveying equipment. Background Art

[0002] At present, the core parts of preform conveying equipment are rectangular in shape, such as Figure 8a-8b On the front side, there are 4 M5 threads that penetrate the 2 φ4.2 and 70mm deep holes on the end face as air inlets; on the back side, there are 20 φ1.2mm oblique holes that also penetrate the φ4.2 and 70mm deep holes on the end face as air outlets, and the R130 arc on the other side is used as a guide. Because these oblique holes are used to blow air to push the bottle embryo to move, there are requirements for the aperture size and position, and there must be no processing burrs to prevent burrs from entering the bottle embryo.

[0003] The most common processing method at present is to use CNC four-axis to rotate the workpiece angle to process inclined holes. The processing technology is complicated and it is difficult to remove the processing burrs, which affects the performance of the parts. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a method for manufacturing core parts of a preform conveying device.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] The manufacturing method of the core parts of the preform conveying equipment is characterized by comprising the following steps:
