Plastic mold the slope is not reduced
Degree than the general type Xinxie large cavity, the cavity length and the depth of the core is larger,plastic mold the slope is not reduced.
Third, the wall thickness
Plastic parts according to the requirements (strength, stiffness) and structural characteristics of products and plastic mold molding process requirements may be
Wall thickness is too small, insufficient strength and stiffness, difficulty filling plastic mold
The wall thickness is too large, increase the cooling time, reduces productivity, bubbles, shrinkage and so on.
Required wall thickness as uniform as possible,plastic mold otherwise the cooling and solidifying speed is not as easy to produce stress, causing plastic deformation and cracking.
Fourth, strengthen tendons
Design principles:
intermediate stiffener is lower than 0.5 mm above the outer wall,plastic mold so that the bearing surface is easy straight.
should be avoided or reduced local accumulation of plastic mold.
tendons row cases to follow the plastic mold direction of flow in the cavity.
