1. Check for Missing Machining Parts : make sure that all the parts required by design have been completed. If there is any missing machining, return directly to the processing department.
2. Check the Appearance : the surface of the slider has no collapsing Angle or collision injury, the surface of the cavity is smooth and flat, there is no sand hole, rust and other defects, and the release direction is not reversed.
3. Check the Chamfer : the part that should be chamfer has been chamfer, and the chamfer is in accordance with the specification.
4. Check the Surface Roughness : the surface roughness of each machining part shall meet the requirements .
Performance Test
1. Hardness Test : According to the steel performance table hardness test, hardness points should be taken in the relatively flat parts as far as possible, and more points in different parts to confirm whether the hardness of the steel is uniform (hardness is not recommended on the rubber surface).
Dimensional Inspection
1. Straight Angle and Verticality Detection: straight Angle and verticality ≤0.02.
2. Other Routine Size Inspection: including the fit position of slide block and slide strip, the size of non-fit position, the size of guide chute, etc. The specific tolerance standards are as follows:
o Slider and Slider Strip Fitting Size: tolerance +0/-0.02
o Non-fit Dimension: tolerance +0/-0.1
o Guide Chute Size: tolerance +0.02/-01.
Specific Inspection Procedures and Tools
1. Preliminary Preparation : After receiving the slide for inspection, first check the surface of the workpiece for impact, paying special attention to the sealing position and cavity for collapse. Remove burrs with a fine oil stone, wipe the oil in the hole, cavity and tendon with alcohol, and then blow it clean with an air gun.
2. Carefully Review the Drawings : confirm the assembly relationship, core-pulling mode, assembly positioning, processing reference, etc., of the slider, so as to clarify the inspection key points and select the appropriate measurement method and inspection tool .
Through the above steps and methods, you can comprehensively check whether the mold slider is qualified.
