[0002] Car light injection molds are precision tools used to manufacture the housings of automotive lamps (such as headlights, taillights, etc.). These molds are usually made of steel with high precision and durability. Because they need to withstand the high temperature and high pressure environment during the injection molding process and can be reused thousands of times to produce consistent products, the hardness of the car light injection mold needs to be tested after it is processed and formed to ensure that the car light injection mold will not be damaged due to quality during subsequent use.

[0004] Although the above-mentioned application and the prior art can provide protection during detection to prevent mold parts from accidentally flying out and injuring people, which is beneficial to ensuring the safety of the staff, when the above-mentioned application and the prior art perform hardness testing on the headlight injection mold, since the surface of the headlight injection mold has a curvature, it is impossible to test the surfaces of the headlight injection mold with different curvatures, and in the process of testing, since the above-mentioned application and the prior art only limit the two ends of the headlight injection mold, when testing the surfaces of the headlight injection mold with different curvatures, the headlight injection mold will be displaced, which will lead to errors in the test results and scratches on the surface of the headlight injection mold, and in the process of testing, when encountering unqualified headlight injection molds for testing, the headlight injection mold will be broken, leaving its fragments inside, thereby affecting the subsequent test efficiency.

The rotating block 21 drives the extrusion plate 222 to rotate to a suitable angle through the driving cylinder 22 and the telescopic column 221. Then, the workpiece is tested at different angles through the test assembly 2. If unqualified workpiece fragments need to be tested, During cleaning, the second driving motor 41 is started, and the second driving motor 41 drives the adjusting screw block 42 to move through the bidirectional screw 411, so that the adjusting screw block 42 drives the two lateral push plates 421 to move away from each other.

[0028] Parallel: The parallelism defined in this application is not limited to absolute parallelism. This definition of parallelism can be understood as basic parallelism, which allows for non-absolute parallelism due to factors such as assembly tolerance, design tolerance, and the influence of structural flatness. Small angular errors are allowed. For example, an assembly error range of less than 10 degrees can be understood as a parallel relationship.

[0029] Vertical: The verticality defined in this application is not limited to an absolute vertical intersection relationship (angle of 90 degrees). It allows for non-absolute vertical intersection relationships caused by factors such as assembly tolerance, design tolerance, and influence of structural flatness. It also allows for errors in a small angle range. For example, the assembly error range of 80 to 100 degrees can be understood as a vertical relationship.
