Description
Technical field
This utility model relates to a kind of plasthetics, particularly relates to a kind of screw column and working of plastics.
Background technology
At present, overwhelming majority plastic parts screw columns, are all that screw column cylinder is directly molded and is connected to housing
On, use this structure, after moulding shapes, be easily generated the situation of shrink, occur at finished surface
Dent mark.
On working of plastics, seeing Fig. 1, screw column is directly to go out certain altitude, spiral shell from upper casing areal stretch
The comparison that the glue position, position contacted between silk post and housing can become is thick, after product injection mo(u)lding, and appearance
The bad flaws such as indenture can be produced, affect the quality of appearance.
Its producing cause is that the facestock at wall thickness is drawn into due to volume contraction during cooling, is becoming
There is dent mark in product surface.Shrink is most in the bad phenomenon that finished surface is occurred, mostly
Betiding at wall thickness, if general pressure declines, shrinking probability will be bigger.
If moulding forming temperature is too high, then at wall thickness, at muscles and bones or high spot reverse side easily occurs
Shrink, this is because the place of easily cooling first solidifies, it is difficult to the raw material of the part of cooling can move towards that
Dynamic, shrink is controlled in the place not affecting quality of finished as far as possible.Typically reduce forming temperature, mould
Temperature reduces the contraction of raw material, but certainly will increase pressure.
Thus do not improve be molded between screw column with housing the contact area being connected excessive in the case of,
Shrink phenomenon has certain probability and occurs.
