Do you understand the fundamentals of precision gear mold manufacturing?
I. Precision machining gear die concept and theoretical application
1. Precision gear is defined as having extremely high parameter size and performance criteria. The parameters are the tip circle's outer diameter, the root circle's outer diameter, the modulus, the index circle's diameter (also known as the common normal), the index circle's thickness, and the pressure. Angle, helical tooth inclination angle, tooth ring runout tolerance, and so on; performance includes material selection and the precision requirements of other assembly parameters.
2. In terms of application, representative goods include internal transmission components of printers and copiers, as well as VCD disc drive brackets. If the gears do not satisfy the precise requirements, the bracket will seem unstable in and out, accompanied by vibration or swinging. The bold, loud voice assists us to obtain a perceptual feeling of the specific notion and its need.
2. Classification of precision gear accuracy The higher the grade, the more accurate the national standard, and the lower the grade, the more accurate the Japanese standard. Most mold companies can only produce grade 4 and grade 5 gears, and the likelihood of producing grade 3 plastic gears is relatively high.
II. Precision plastic gear types:
1. It may be separated into spur gears, helical gears, combined spur gears, combined helical gears, and combination straight helical gears based on the axial inclination of the teeth. This combination is based on a trapezoidal distribution of spur or helical gears in the axial direction, as well as one-shot injection molding.
3. Transmission gears are classified into two types: meshing transmission gears and belt transmission gears.
III. Precision gear mold base selection:
The precision of the mold base can have a direct impact on the mold's manufacture, the accuracy of the injection molded product, and the mold's life. Practice has shown that meeting the criteria of the gear die requires a high level of die accuracy.
