As the "judge" of automobile manufacturing, automotive inspection tools have obvious advantages in the process of modern mold manufacturing, which can improve production efficiency and control quality. They are suitable for large-scale production of goods, such as automotive parts, to replace professional measuring tools, such as smooth plug gauges, threaded plug gauges, outer diameter calipers, etc. Why?

Firstly, the inspection of the car inspection tool holes requires independent inspection of many major holes and flanges in the stamped parts of the vehicle body. In the planning of inspection tools, a protrusion with a thickness of about 1mm is usually added to the surface of the inspection details. The base of the protrusion is on the same axis as the workpiece hole base, with a diameter 5mm larger than the aperture. The double marking method is used to inspect the protrusion. When the accuracy of the measured hole is requested to be high, the positioning hole method is used to check with a plug gauge and a bushing.

Regarding the planning of the bottom plate assembly for automotive inspection tools, the outer surface should be stretched along the reference plane direction for a certain distance in the inspection details, so that its lowest point is greater than a thickness of 150mm, to ensure that the inspection details have sufficient strength. Together, the inspection details should strive to ensure that the bottom surface, i.e. the upper surface (base surface) of the bottom plate assembly, is at an integer position in the vehicle coordinate system. The inspection detailed bottom plate assembly is generally composed of a base plate, channel steel (if necessary, processed with steel in the middle), positioning blocks, and universal wheels. After the base plate is fixed by the inspection detailed plate, other components can be selected according to the standard type according to practical conditions.

In the manufacturing process of molds, trimming and punching processes have always been difficult points, especially for some large automotive molds with disorderly structures such as oblique cutting, oblique punching, and oblique flipping. The determination of trimming lines is not simple if traditional manufacturing methods are used, and it requires repeated exploration several times or even ten times, which brings great workload to fitters and processing equipment. Not only does it require higher skill levels of fitters, but it will seriously affect the debugging of subsequent process molds. Moreover, in practice, many trimming and punching molds use alloy steel as the cutting edge material from a cost perspective, If traditional edge trimming mold manufacturing methods are used, it is inevitable that the cutting edge will be repeatedly welded, because during the process of repeated welding, the material will crack easily, causing the insert to become invalid and having to be reworked from scratch. This not only delays the cycle, but also significantly increases the cost of mold manufacturing.
