Improve the connector mould process: a case study
Connector Mould process Requirements are as follows:
1. Pursue the mirror discharge matte effect while maintaining the size
2. Customizable lettering
3. No burrs, lack of material, shrinkage, cracks, scorch, strain, chromatic aberration, and other defects for Connector Moulding
4. Pay attention that this material is easy to cloak, pay attention to the roughness of the parting surface (fine grinding)
5. The product cavity accuracy is controlled within ±0.005
How to solve problems
1. Unsaturated mold, with burrs;
2. Serious deformation / inconsistent size of hole cloak;
3. Dip the front mold;
4. The appearance is inconsistent;
Reason
1. Connector Mould process Poor exhaust;
How to do?
①Increase exhaust gas;
②After the assembly of all sizes is OK, make the pattern uniformly; similar products need to improve the position of the glue feeding method
2. The glue feeding method is unreasonable, and there are certain reasons for the material and machine adjustment;
How to do?
①Improve the glue position, feed glue at two wall thickness positions, increase the thimble,
② Bottom hole inserts increase the draft angle
③Increase the mold temperature
④Re-select materials
3. The glue position of the needle is long, and there is no draft angle;
How to do?
①Connector Mould process the back of the ejector pad is 0.13mm
②The inner needle and the back needle of the cylinder are adjusted and replaced at the same time
③Precise positioning Front and rear die exchange and installation
Connector Mould manufacturers to have to complete sometimes has to work in parallel with the customer, and must review with the customer within the mold maker.
Improvements, modifications and selections made at the beginning of the project will most likely affect the end result, including part cost.
