Abstract
The utility model discloses a die exhaust device, which comprises suction grooves and suction holes. The die exhaust device is characterized in that the suction grooves are formed on a die outer ring, and the suction holes are formed on a die inner ring; the suction grooves are parallel to the suction holes; the interval of the suction holes is 50 mm; and a suction hole is correspondingly formed at a position of less than 50 mm in each suction groove. The die exhaust device is simple in structure, convenient to use and high in efficiency; and through the suction grooves and the suction holes with high density, gas in a die is timely exhausted, so that the device is very important for the whole injection molding production process, and the quality of a product is improved.
Description
Technical field
The utility model relates to a kind of die venting device.
Background technology
With the heat distortion temperature of mold cavity surface heating to plastics, injected plastic then, in the injection moulding process, the temperature of mould remains unchanged, and the temperature of complete rear mould drops to the taking-up product gradually, and next injection treatment starts, and die surface heats rapidly.Mold temperature raises and reduces all very fast.
Mainly be for mould.Offer even distribution water route in mould die and the outward appearance slide block, utilize high-temperature high-pressure steam to be the Fast Heating media, chilled water is used air tracheae air pressure again for the cooling media, sees through RHCM(high-speed and high-temperature forming technique), in plastics, add glass fibre, produce the shell with reflecting effect, RHCM can solve the product problems such as the insoluble joint line of common moulding, current mark, and equipment switches in the water route in die and sliding field, heating, cooling die.
Use the high-temperature high-pressure steam rapidly heating moulds to higher temperature (120 degree) in injection front cavity and the slide block in the water route.
Utilize steam to keep temperature in the injection.
Stop to supply with steam in the water route in the complete die of injection and the slide block, blow clean residual aqueous vapor in the water route with air duct air pressure, turn again logical chilled water and carry out the mould fast cooling.
Drop to proper temperature, ejection mold-opening enters second circulation after the product cooling.But it is exactly a fast heating that RHCM equipment is equivalent to, fast cooling die.
Because mould area breaking broad in the middle causes a large amount of device in Gas to discharge, for avoiding secondary operations, need a kind of die venting device of design.
The utility model content
Purpose: in order to overcome the deficiencies in the prior art, the utility model provides a kind of die venting device simple in structure, esy to use, safe and reliable.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is: the die venting device comprises: air-breathing groove and suction hole is characterized in that: described air-breathing groove is arranged on the mould outer ring, and described suction hole is arranged on the mould inner ring; Parallel corresponding setting the with suction hole of described air-breathing groove.
As preferred version, the spacing between the described suction hole is 50mm; Wherein the position of the not enough 50mm of air-breathing groove also correspondence a suction hole is set.
Beneficial effect: the die venting device that the utility model provides, simple in structure, easy to use, efficient is high, by the air-breathing groove of arranging of large density and suction hole, in time discharges the gas of mould inside, extremely important for whole injection moulding production process, improved the quality of product.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of B among Fig. 1;
Fig. 3 is A-A face sectional drawing among Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As Figure 1-3, the die venting device comprises: air-breathing groove 1 and suction hole 2, and air-breathing groove 1 is arranged on the mould outer ring, and suction hole 2 is arranged on the mould inner ring; Air-breathing groove 1 and suction hole 2 parallel corresponding settings.
As preferred version, the spacing between the described suction hole 2 is 50mm; Wherein the position of air-breathing groove 1 not enough 50mm also correspondence a suction hole 2 is set.
The die venting device that the utility model provides, simple in structure, easy to use, efficient is high, by the air-breathing groove of arranging of large density and suction hole, in time discharges the gas of mould inside, and is extremely important for whole injection moulding production process, improved the quality of product.
Below disclose the utility model with preferred embodiment, so it is not to limit the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode obtains, all drops within the protection domain of the present utility model.
