What is the point of view of designing injection mold products?
Opening direction and typing line Each injection product must first determine its opening direction and profile at the beginning of the design to ensure that the core slider mechanism is minimized and the contour’s influence on the appearance is eliminated. After determining the opening direction, design the product’s stiffening ribs, traps, protrusions and other structures to avoid pulling the injection mold to reduce the joint line to reduce the seam line and extend the molding time and the life of the injection mold.
After determining the opening direction, you can select the appropriate type line to avoid reverse buckle in the opening direction, thereby improving the appearance and performance. The proper stretching angle of the water angle can avoid the product being pulled out. The smooth surface of the drinking water should be greater than or equal to 0.5 degrees, the surface of fine particles should be greater than 1 degree, and the surface of rough particles should be greater than 1.5 degrees.
Proper patterning angle can prevent the top from being damaged, such as top or white, deformed and bursting. When designing a deep cavity, the slope of the outer surface should be greater than the slope of the inner surface to ensure that the core does not tilt during injection to obtain a uniform product wall thickness and ensure the opening strength of the material product.
The wall thickness of injection mold products has a certain range of wall thickness, usually 0.5 to 4mm. When the wall thickness exceeds 4 mm, it will cause problems such as cooling time, leading to shrinkage, and changing the product structure should be considered. The uneven wall thickness causes surface shrinkage. The uneven wall thickness causes pores and welding lines. Strengthen Reasonably use ribs to increase the rigidity of the product and reduce deformation.
