What should be paid attention to in molding die?
Gate location and shape of the selection is reasonable, to improve and ensure the quality of plastic products molding have certain effect, can reduce or eliminate weld line, for example, reduce the internal stress of products, product appearance, size accuracy and surface level off is smooth.The selection of gate position in the mold should pay attention to the following points.
When arranging gate position, it is necessary to reduce the flow of molten material as much as possible.
To facilitate the discharge of air in the cavity.
The number of gates should be reduced as far as possible under the condition of filling the mold cavity.
The influence of the weld line on the strength of the product should be paid attention to.
In the case of a thin - shaped cavity, the injection mold should be filled with a plurality of gate points or a fan gate side feed.
When the wall thickness of the products is not at the same time, the gate should be located in the wall thickness to reduce or avoid the bubbles in the product.
The gate position should avoid the core and insert, so as to avoid the movement or deformation of the core or embedded parts.What should be paid attention to in molding die?
