Do you know about the 10 rules of mold design and type? The injection mold factory will give you a comprehensive introduction to what these ten principles refer to.

1.Consideration of clamping force

The lateral clamping force of the mold is relatively small, so for large products with larger projected areas, the direction of the larger projected area should be placed in the direction of the front and rear mold opening and closing, and the side with the smaller projected area as the side向 分 型。 To type.

2.Meets product demolding requirements

The parting surface is also for the product to smoothly remove the mold. Therefore, the position of the parting surface should be selected at the position where the product section size is large. This is a basic criterion.

3. Shape of parting surface

For general products, a parting surface that is straight with the direction of the mold opening movement of the injection molding machine is often used. In special cases, parting surfaces of other shapes are used. The shape of the parting surface is based on facilitating processing and demolding. Like a zigzag product, it must be based on its zigzag curvature when parting.

4.Ensure product appearance and quality

Do not choose the parting surface on the appearance of product lubrication. Appearance surface is generally not allowed to have clips and other lines that affect aesthetics; some products with concentricity requirements, you must put all the parts with concentricity requirements on the same side, so as to ensure their concentricity.

5.Confirmation of orientation

When determining the orientation of the product in the mold, the selection of the parting surface should try to prevent the product from forming side holes or side buckles, and should prevent the use of complex mold structures.

6. Conducive to demoulding

The general mold release structure of the mold is in the moving mold, so when selecting the parting surface, the product should be left in the moving mold as much as possible. Therefore, for some places that may stick to the fixed mold, we often add fixed mold to assist the demolding organization.

7.Considering the lateral mold opening interval

Generally, the interval of the lateral mechanical mold opening is relatively small. Therefore, when selecting the parting surface, the long core pulling direction should be selected in the direction of the front and rear mold opening and closing, and the short direction should be used as the side parting.

8.Easy to process mold parts

When selecting the parting surface, the mold should be divided into easy-to-machine parts to reduce the difficulty of machining.

9. Conducive to exhaust

When the parting surface is used as the primary exhaust, the parting surface should be designed at the end of the movable plastic to facilitate the exhaust.

10.R typing

With regard to the mold design of many products, there is a full circle of R angles on the parting surface. At this time, the Rzui good parting must be taken into consideration, and no sharp side can appear.
