Abstract
The utility model discloses a degassing type injection mold which comprises a bottom mold (1) and a top mold (2), and is characterized in that a feed opening (3) used for filling an injection molding material is formed in the top mold (2); the feed opening (3) is fixedly connected with a feed pipe (4); and the feed pipe (4) comprises a vertical pipe (5), an inclined pipe (6) and a degassing device (8) used for connecting the vertical pipe (5) and the inclined pipe (6). According to the degassing type injection mold provided by the utility model, due to the degassing device, the injection molding material is subjected to degassing operation before injection molding, air bubbles on the surface of and inside the molded plastic part are avoided, particularly for some plastic parts with high machining precision requirement and without air bubbles, the quality completely accords with the standard, and the yield and production efficiency of the plastic part are improved.
Description
Technical field
The utility model relates to a kind of degassed formula injection mold, belongs to technical field of mold.
Background technology
At present, generally utilize mould to produce in manufacturing enterprise, its operating efficiency is high, easy to operate.The injection molding molding cycle of thermoplastic is short, production efficiency is high, and injected plastics material is little to the wearing and tearing of mould, the plastic that forming shape complexity, picture on surface and mark are clear in large quantity, dimensional accuracy is high.
But; existing injection mold does not generally have degassed function; air in injected plastics material can not be discharged in time; after moulding, the surface of plastic and inside 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; caused the waste on man-hour and production cost, production efficiency is extremely low.
Utility model content
Technical problem to be solved in the utility model is, a kind of have degassed function, injection mold that degasifying effect is good are provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of degassed formula injection mold, comprise: bed die and backform, it is characterized in that, on described backform, be 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 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 °, on described tipping tube and the perpendicular setting of described degasser and described degasser, be provided with for by the through hole of 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 on outside and its sidewall of described commissioning pipe and 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, in independently unit of degasser, be in vacuum pump chamber, by predefined vacuum, the continuous low cruise of vavuum pump, flow through under the effect of vavuum pump in the vacuum chamber degassing film pipe of a section very short of injected plastics material, under vacuum action, in injected plastics material, dissolved gases is discharged by degassing orifice.
The setting of attemperator, makes the injected plastics material of molten condition in the process of commissioning pipe of flowing through, can not cause because tube wall temperature is poor the phenomenon of condensing, and guarantees that whole injected plastics materials all flow 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 that the utility model provides, the setting of degasser, make injected plastics material before injection mo(u)lding, just carry out degassed operation, ensure the surperficial and inner without bubble of moulding plastic, especially high for some requirement on machining accuracy, can not alveolate plastic, quality meets standard completely, has improved yield rate and the production efficiency of plastic; The setting of attemperator, makes the injected plastics material of molten condition in the process of commissioning pipe of flowing through, can not cause because tube wall temperature is poor the phenomenon of condensing, and guarantees that whole injected plastics materials all flow into the injection molding cavity between bed die and backform with the state of liquid.
