What is the general drawing Angle of the injection mold?

The drawing Angle of the injection mold refers to the Angle of the mold wall and the product tilt set in order to ensure the smooth release of the product during the injection molding process. In general, the common draw Angle range is 1° to 3°. The size of the drawing Angle has an important effect on the quality and production efficiency of the injection molding product.

The following is a detailed introduction to the drawing Angle of the injection mold:

(1) Determination of drawing Angle:

Determining the Angle of drawing requires a combination of factors.
1, need to consider the shape and structural characteristics of the product, such as whether there is chamfer, wall thickness change. More complex products may require a larger draw Angle to ensure a smooth release.
2, also need to consider the shrinkage and fluidity of the material, different materials have different shrinkage and fluidity, the requirements of the drawing Angle will also be different.
3, also need to consider the structure of the mold and manufacturing process, mold design and processing accuracy will also have an impact on the choice of drawing Angle.

(2) Common drawing Angle range:

The size of the drawing Angle will be affected by many factors, such as product shape, material characteristics, mold structure and so on. In general, the common draw Angle range is 1° to 3°. This range is considered to be a safe and practical choice and can meet the release needs of most injection molding products.

(3) The role of drawing Angle:

The main role of the drawing Angle is to make the injection molding product can be smoothly removed from the mold, to avoid the problem of product deformation, damage or clamping due to excessive friction. The appropriate drawing Angle can reduce the contact area between the mold and the product, reduce the friction during demoulding, and improve the demoulding effect.

(4) Adjustment of drawing Angle:

In actual production, if it is found that the product is difficult to release or damaged, the drawing Angle can be adjusted appropriately. Increasing the draw Angle can improve the release effect, but it may also cause scratches or other problems on the surface of the product. Therefore, it is necessary to carry out adequate testing and verification when adjusting the drawing Angle to ensure the balance of the demoulding effect and product quality.

In short, the drawing Angle of the injection mold is an important parameter, which has an important impact on the quality and production efficiency of the injection product. Reasonable selection and adjustment of drawing Angle can ensure smooth release of products, improve production efficiency, and ensure product quality.
