Widely used dry die & mould manufacturing industry, is one of the important technology and equipment, industrial production has a high production efficiency, good quality, less cutting, save energy and raw materials, low cost, a series of advantages, has become the most development potential of a molding process.
In this paper, by using Pro/E software, to filter the kettle handle design for plastic injection mould.
1 structure of manufacturability analysis filter kettle handle plastic parts structure as shown in figure 1.
The parts of arc is more, more also concave and irregular structure, so the mold design and manufacture of relatively complex.
Plastic parts for appearance, beautiful surface requirements.
Wall thickness thin plastic, side there are two side core-pulling ensure molding complete, when the design should consider molding integrity, does not produce shrinkage cavity and buckling deformation, try to stay away from the corners in right Angle to prevent the accumulation of internal stress.
Side holes side has two parts, the need when molding with side core-pulling structure, because the side core-pulling slider is bigger, plastic pieces of big package of side core force, so the two side slide block core touch wear surface with high accuracy.
From the point of local structure, one of plastic arc of perforation, on both sides of the concave groove, lower part of plastic parts and a hook, request the surface roughness is higher, therefore, the cavity has a high accuracy requirement.
