Description
Technical field
The utility model belongs to injection technical field of membrane, more particularly to a kind of multi-station injection sizing Integral mold.
Background technology
Injection molding is that high-temperature fusion plastics are expressed to a kind of method being molded in die cavity, its be also plastics it is main into
Type method, feature is that production efficiency is high, and the flexibility (adaptability) of operation to various plastics is strong, and energy forming shape is complicated, accurate in size note
Molding product, application field is extensive.Its production process is：First the solid plastics of granular (or powdery) are plastified into uniform close
The good plastic melt of plasticity of degree, viscosity and composition, then this kind of plastic melt is possessed one by applying certain pressure
Constant current is fast and injects and enters in the die cavity of mould, after plastic melt cooling and shaping, just can obtain and die profile one
The plastic products of cause.
But be due to mould filling velocity it is slower, dynamic model, cover half temperature it is inconsistent, product is not fully hardened just to be pushed away
The reason such as go out, inevitably in molding part internal residual partial interior stress, along with later stage cast gate overlap processing etc., so that
Cause product warpage, bending, distortion and the not first-class metaboly of thickness, this is one of most common defect of plastic products, is this
On the other hand on the one hand enterprise take one by adjusting molding proces s parameters during injection molding to reduce deflection
A little supplementary means reduce product deformation, such as individually product are cooled down, it is necessary to be equipped with cooling shaping fixture, and its cost is high, effect
Rate is also low；Or be that corner etc. is gone using single mechanical device, it not only increases process, also add equipment cost,
Efficiency is still very low.
