Description
Technical field
The present invention relates to a kind of degassed formula injection mold, belong to technical field of mold.
Background technology
At present, in manufacturing enterprise, generally utilize mould to produce, its operating efficiency is high, easy to operate.The shaping molding cycle of thermoplastic injection is short, production efficiency is high, and the wearing and tearing of injected plastics material to mould are little, can complicated, the picture on surface of forming shape and mark is clear, dimensional accuracy is high plastic in large quantity.
But; existing injection mold does not generally have degassed function; air in injected plastics material can not be discharged in time; surface and the inside of shaping rear plastic often there will be pore; especially high for some requirement on machining accuracy, can not alveolate plastic, utilize existing explained hereafter plastic qualification rate out low, rework rate is high; cause the waste on man-hour and production cost, production efficiency is extremely low.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of and has degassed function, injection mold that degasifying effect is good.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of degassed formula injection mold, comprise: bed die and backform, it is characterized in that, described backform is provided with the dog-house for inserting injected plastics material, described dog-house is fixedly connected with commissioning pipe, described commissioning pipe comprises vertical tube, tipping tube and the degasser for being connected described vertical tube and tipping tube, one end of described vertical tube is connected with described dog-house, the other end is connected with the discharging opening of described degasser, one end of described tipping tube is connected with the charging aperture of described degasser, the angle of described tipping tube and vertical tube is 100 ~ 130 °, described tipping tube and the perpendicular setting of described degasser and described degasser is provided with for the through hole by injected plastics material, the upper surface of described degasser is also provided with degassing orifice, described degassing orifice is connected with the steam vent of attemperator upper surface, described attemperator is positioned at the outside of described commissioning pipe and its sidewall is provided with for the hole through described tipping tube.
Described degassing orifice is connected with described through hole.
Injected plastics material enters in degasser via the charging aperture of degasser, at degasser independently unit, namely in vacuum pump chamber, by the vacuum preset, the continuous low cruise of vavuum pump, injected plastics material is at the flows by action of the vavuum pump degassing film pipe of a section very short in vacuum chamber, and under vacuum, in injected plastics material, dissolved gases is discharged by degassing orifice.
The setting of attemperator, makes the injected plastics material of molten condition can not cause the phenomenon of condensation due to tube wall temperature difference in the process flowing through commissioning pipe, guarantees that whole injected plastics material all flows into the injection molding cavity between bed die and backform with the state of liquid.
The lower surface of described backform is provided with groove, and the opening of described groove and described bed die adapts.
Described attemperator comprises resistive heater and insulation packaging material, and described resistive heater is wound in the outside of described commissioning pipe, and described insulation packaging material is coated on the outside of described commissioning pipe.
Described insulation packaging material is cotton or cotton wool felt.
Described degasser is fixedly connected with the madial wall of described attemperator.
The material of described vertical tube and tipping tube is stainless steel tube or PPR plastic tube.
The degassed formula injection mold of one provided by the invention, the setting of degasser, injected plastics material is made just to have carried out degassing operation before injection mo(u)lding, ensure surface and the leaving no air bubbles inside of shaping plastic, especially high for some requirement on machining accuracy, can not alveolate plastic, quality meets standard completely, improves yield rate and the production efficiency of plastic; The setting of attemperator, makes the injected plastics material of molten condition can not cause the phenomenon of condensation due to tube wall temperature difference in the process flowing through commissioning pipe, guarantees that whole injected plastics material all flows into the injection molding cavity between bed die and backform with the state of liquid.
