Abstract
The invention discloses an exhaust device of a mold, comprising air absorbing grooves and air absorbing holes. The exhaust device is characterized in that the air absorbing grooves are arranged at the outer ring of the mold; the air absorbing holes are arranged in the inner ring of the mold; the air absorbing grooves and the air absorbing holes are correspondingly arranged in parallel; the distance between the air absorbing holes is 50mm; and the parts less than 50mm of the air absorbing grooves are also correspondingly and respectively provided with one air absorbing hole. The exhaust device disclosed by the invention has the advantages that the structure is simple, the use is convenient and the efficiency is high; by large-density arrangement of the air absorbing grooves and the air absorbing holes, the air in the mold can be exhausted in time, which is very important in the whole injection molding production process, so that the quality of a product is improved.
Description
Technical field
The present invention relates to a kind of die venting device.
Background technology
The mold cavity surface is heated to the heat distortion temperature of plastics, injected plastic then, in the injection moulding process, the temperature of mould remains unchanged, and the temperature of the back mould that finishes 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 to 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 medium, chilled water is the cooling medium; Use air tracheae air pressure again, see through RHCM (high-speed and high-temperature forming technique), in plastics, add glass fibre; Produce the shell with reflecting effect, RHCM can solve 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.
Before the injection in die and the slide block in the water route with the high-temperature high-pressure steam rapidly heating moulds to higher temperature (120 spend).
Utilize steam to keep temperature in the injection.
Stop to supply with steam in the water route in intact die of injection and the slide block, blow clean residual aqueous vapor in the water route, change logical chilled water again and carry out the mould fast cooling with air duct air pressure.
Drop to proper temperature, eject die sinking after the product cooling and get into second circulation.RHCM equipment is equivalent to be exactly one can heat fast, fast cooling die.
Because mould area breaking broad in the middle causes a large amount of Device in Gas to discharge,, need a kind of die venting device of design for avoiding secondary operations.
Summary of the invention
Purpose: in order to overcome the deficiency that exists in the prior art, the present invention 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 scheme that the present invention adopts is: the die venting device comprises: air-breathing groove and suction hole is characterized in that: said air-breathing groove is arranged on the mould outer ring, and said suction hole is arranged on the mould inner ring; Parallel corresponding setting of said air-breathing groove with suction hole.
As preferred version, the spacing between the said suction hole is 50mm; The position of the not enough 50mm of wherein air-breathing groove also correspondence is provided with a suction hole.
Beneficial effect: die venting device provided by the invention; Simple in structure, easy to use, efficient is high, through air-breathing groove of being provided with of big 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 a structural representation of the present invention;
Fig. 2 is the partial enlarged drawing of B among Fig. 1;
Fig. 3 is an A-A face sectional drawing among Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done explanation further.
Shown in Fig. 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 said suction hole 2 is 50mm; The position of wherein air-breathing groove 1 not enough 50mm also correspondence is provided with a suction hole 2.
Die venting device provided by the invention, simple in structure, easy to use, efficient is high, through air-breathing groove of being provided with of big 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 present invention with preferred embodiment, so it is not in order to restriction the present invention, and all employings are equal to replacement or the technical scheme that obtained of equivalent transformation mode, all drop within protection scope of the present invention.
