Cross precision die and carry out injection moulding acquisition, and in injection molding, typically using underlying dynamic model toward above
To realize matched moulds, after the completion of injection, dynamic model is moved away from cover half to complete die sinking down again for cover half movement, now, ideally, produces
Product should be fitted on dynamic model and completed with dynamic model to mold, but in actual production, due to the thickness of high-accuracy silicone skirt piece
Degree and quality very little, it is single to rely on its own gravity to ensure that it is quite unreliable on dynamic model that it stably be fitted in, often occur
It is fitted on cover half, and so, during die sinking, high-accuracy silicone skirt piece easily drops from cover half and causes to damage, and i.e.
After making die sinking, high-accuracy silicone skirt piece can be finally fitted on dynamic model, it is also possible to which one part is patch during die sinking
Close on cover half, simply finally influenceed by mould opening force and separated, such case easily causes the torsional deformation of product, has a strong impact on
The precision of product.
