Precision mold selection gate position to follow the principle. |
When designing the casting system, the location of gate is selected first. Gate position selection direct relationship injection molding to product molding quality and injection process smoothly, gate location selection to follow several principles?
1. The gate position should be selected on the parting surface, so that it can be cleaned when the mold is processed and used.
2. The distance between each part of the mold design distance should be as consistent as possible, and the process should be the shortest;
3. The position of the gate should ensure that the plastic injection molding cavity is smooth and thick, so that the plastic can flow in smoothly.
4. The gate position should be at the thickest part of the section of the plastic part;
5. Avoid the direct impact of plastic on the wall, core or insert, so that the plastic can flow into various parts of the cavity as soon as possible, and the mold injection molding machine process video and avoid the mold core or insert deformation;
6. Try to avoid making the products produce weld marks, or make their welding marks to be produced in the non-essential parts of the products;
7. The gate position and the direction of the plastic flow should make the plastic flow into the cavity parallel to the flow and facilitate the discharge of the gas in the cavity.
The last point is that the gate should be set to the most easily removed parts of the product, while minimizing the appearance of the product.
