Common Terminology For Mold Design

- Aug 14, 2018-

1. Stamping: The stamping is the collective name of the billet after one or more stamping processes, which is the collective name of the workpiece and the workpiece.


2. Glossy: Glossy is a bright section of the blank that is cut out.


3. Rebound: There are two kinds of rebound, one is the difference between the size of the formed punch after being taken out of the mold and the corresponding size of the mold. For curved parts, it is generally expressed as an angular difference or a difference in radius. The other is the difference between the outer dimensions of the blanks that escape from the mold and the corresponding dimensions of the female molds or the difference between the inner dimensions and the corresponding dimensions of the punches.


4. Closing height closure: The closing height is the distance between the upper plane of the upper mold base or the plane of the lower mold base when the die is at the pole of the working position.


5. Stroke: The stroke is the distance between the ends of the upper and lower movements of the press slider. It is customary to refer to the up and down movement of the press slider as a stroke, such as "stroke down", "stroke up", "number of strokes per minute", and so on.


6. Negative rebound: Negative rebound is the rebound of the radius of curvature after the shaped punch is removed from the mold, or the rebound of the material body after the punching member escapes from the mold.


7. Clamping feeding device: The clamping feeding device is a device for feeding raw materials into a die by clamping, relaxing and reciprocating motion of a mechanical, pneumatic or hydraulic machine.


8. Life: Lifetime refers to the number of times a die can be stamped once per grinding or the number of times a die can be stamped before it is scrapped. The former is called sharpening life and the latter is called total life.


9. Step: The step is the distance that each raw material that can be used for multiple stampings is fed at a time.


10. Gap: The gap is the difference between the corresponding dimensions of the punch and the die that cooperate with each other or the gap therebetween.


11. Single-sided gap: A single-sided gap is a gap from the center to one side or a gap on one side.


12. Blanks: Blanks are raw materials that are not stamped and are mostly used for one stamping. Blanks are sometimes referred to as blanks or wool.


13. Coil: Coil is a roll of raw material that can be used for multiple stamping.


14. Sheet: The sheet material is a sheet-like raw material that can be used for multiple stamping.


15. Strip: Strip is a strip of raw material that can be used for multiple stamping.
