What should be paid attention to when designing a good mold procuded by small Cnc Milling Machine V1165

1. Mold opening direction and parting line

   Each injection product must first determine its mold opening direction and parting line at the beginning of the design to ensure that the core-pulling slider mechanism is minimized and the effect of the parting line on the appearance is eliminated.

1. After the mold opening direction is determined, the product's ribs, buckles, protrusions and other structures should be designed to be consistent with the mold opening direction as much as possible, so as to avoid core pulling and reduce seam lines and extend the life of the mold.

2. After the mold opening direction is determined, an appropriate parting line can be selected to avoid undercutting in the mold opening direction to improve the appearance and performance.

Second, the draft angle

1. Appropriate demoulding angle can avoid product fuzzing (drawing). The demolding slope of the smooth surface should be ≥0.5 degrees, the fine dermal grain (sand surface) surface is greater than 1 degree, and the coarse dermal grain surface is greater than 1.5 degrees.

2. Appropriate demoulding angle can avoid product top damage, such as top white, top deformation, and top break.

3. When designing deep cavity structure products, the outer surface slope should be greater than the inner surface slope as much as possible to ensure that the mold core is not deviated during injection molding, to obtain uniform product wall thickness, and to ensure the material strength of the product opening.

3. Product wall thickness

1. All kinds of plastics have a certain range of wall thickness, generally 0.5～4mm. When the wall thickness exceeds 4mm, it will cause excessive cooling time and shrink printing, so you should consider changing the product structure.

2. Uneven wall thickness will cause surface shrinkage.

3. Uneven wall thickness will cause pores and weld marks.

Fourth, stiffener

1. Reasonable application of reinforcing ribs can increase product rigidity and reduce deformation.

2. The thickness of the stiffener must be ≤ (0.5～0.7) T product wall thickness, otherwise it will cause surface shrinkage.

3. The single-sided slope of the stiffener should be greater than 1.5° to avoid top damage.

Five, fillet

1. Too small rounded corners may cause stress concentration in the product, leading to product cracking.

2. Too small rounded corners may cause stress concentration in the mold cavity, resulting in cavity cracking.

3. Setting reasonable rounded corners can also improve the processing technology of the mold. For example, the cavity can be directly milled with an R cutter to avoid low-efficiency electrical processing.

4. Different rounded corners may cause the parting line to move, so you should choose different rounded corners or clear corners based on the actual situation.

Six, holes

1. The shape of the hole should be as simple as possible, generally round.

2. The axial direction of the hole is consistent with the direction of mold opening, which can avoid core pulling.

3. When the length to diameter ratio of the hole is greater than 2, the demolding slope should be set. At this time, the diameter of the hole should be calculated according to the minor diameter size (the largest physical size).

4. The aspect ratio of blind holes generally does not exceed 4. Anti-hole pin punching

5. The distance between the hole and the edge of the product is generally greater than the hole size.

Seven, the core-pulling and slider mechanism of the injection mold and avoidance

1. When the plastic part cannot be demolded smoothly in the mold opening direction, the core-pulling slider mechanism should be designed. The slider of the core-pulling mechanism can form a complex product structure, but it is easy to cause defects such as product stitching, shrinkage, etc., and increase the cost of the mold and shorten the life of the mold.

2. When designing injection products, if there is no special requirement, try to avoid core pulling structure. For example, the direction of the hole axis and ribs is changed to the mold opening direction, using methods such as cavity core collision.

Eight, one-piece hinge

1. Using the toughness of PP material, the hinge can be designed to be integrated with the product.

2. The size of the film used as a hinge should be less than 0.5mm and kept uniform.

3. When injecting an integral hinge, the gate can only be designed on one side of the hinge.

Nine, inserts

1. Inserting inserts in injection molded products can increase local strength, hardness, dimensional accuracy and set small threaded holes (shafts) to meet various special needs. At the same time, it will increase product costs.

2. The insert is generally copper, but it can also be other metal or plastic parts.

3. The part of the insert embedded in the plastic should be designed with anti-rotation and anti-pull-out structure. Such as: knurling, hole, bending, flattening, shaft shoulder, etc.

4. The plastic around the insert should be appropriately thickened to prevent stress cracking of the plastic.

5. When designing inserts, fully consider its positioning method in the mold (holes, pins, magnetism)

10. Logo

The product identification is generally set on the inner surface of the product on a relatively flat surface, and adopts a convex form. Choose the surface where the normal direction and the mold opening direction ruler may be consistent to set the identification to avoid strain.

11. Precision of injection molded parts

Due to the inhomogeneity and uncertainty of the shrinkage rate during injection molding, the accuracy of injection molded parts is significantly lower than that of metal parts. The dimensional tolerances of mechanical parts cannot be simply applied. The appropriate tolerance requirements should be selected according to the standard. my country also issued GB/ in 1993 T14486-93 "Engineering Plastic Molded Plastic Parts Dimension Tolerance", the designer can determine the dimensional tolerance of the parts according to the plastic raw materials used and the requirements of the parts, and according to the regulations in the standard. At the same time, it is necessary to determine the appropriate design tolerance accuracy according to the comprehensive strength of the factory and the design accuracy of the products of the same industry.

12. Deformation of injection molded parts

Improve the rigidity of the injection product structure and reduce deformation. Try to avoid flat structure, set flanging, concave-convex structure reasonably. Set reasonable stiffeners.

13. Deduction

1. The buckle device is designed to share multiple buckles at the same time, so that the overall device will not be inoperable due to the damage of individual buckles, thereby increasing its service life, and adding more filter and rounded corners to increase strength.

2. The tolerance requirements for the relevant dimensions of the buckle are very strict. Too many undercut positions are likely to cause damage to the buckle; on the contrary, if the undercut position is too small, the assembly position is difficult to control or the assembly part is too loose. The solution is to reserve a way to change the mold and add glue easily.

14. Welding (hot plate welding, ultrasonic welding, vibration welding)

1. The use of welding can increase the strength of the connection.

2. The use of welding can simplify product design.

15. Reasonable consideration of the contradiction between process and product performance

1 When designing injection products, the contradiction between product appearance, performance and process must be considered comprehensively. Sometimes a part of the manufacturability can be sacrificed to get a good appearance or performance.

2 When the structural design cannot avoid injection defects, try to make the defects occur in the hidden parts of the product as much as possible.

16. The relationship between the diameter of the screw post and the diameter of the self-tapping screw

M2 1.7mm

M2.3 2.0mm

M2.6 2.2mm

M3 2.5mm picture

17. BOSS design principles:

1. The pillar should not be used alone as much as possible. It should be connected to the outer wall or used with reinforcing ribs as far as possible. The purpose is to strengthen the strength of the pillar and make the rubber flow more smoothly.

2. The height of the pillar is generally not more than two and a half times the diameter of the pillar. Excessively high struts will cause air trapping during the molding of plastic parts (too long length will cause pores, scorching, insufficient filling, etc.).

3. If the height of the pillar is more than two and a half times the diameter of the pillar, especially the pillar far from the outer wall, the method to strengthen the strength of the pillar is to use stiffeners

4. The shape of BOSS is mainly round, other shapes are not easy to process

5. The position of the BOSS should not be too close to the corner or the outer wall, and should keep a distance from the outer wall of the product

6), around the BOSS can remove part of the thick flesh (that is, open the crater) to prevent shrinkage and subsidence

7) Boss's draft angle: usually 0.5° outside, 0.5° or 1 inside
