Abstract
The invention discloses a mold air exhausting device which comprises air exhausting blocks. The mold air exhausting device is characterized in that the air exhausting blocks are distributed on corners of a mold; the air exhausting blocks comprise air exhausting channels; the mold air exhausting device comprises an upper mold air exhausting device and a lower mold air exhausting device; the air exhausting channels are formed between the upper mold air exhausting device and the lower mold air exhausting device; and the air exhausting channels are saw-tooth-shaped channels. The mold air exhausting device provided by the invention is simple in structure, is convenient to use, and is high in efficiency, and through the arrangement of the air exhausting blocks in high density in the mold, air in the mold is exhausted rapidly and timely, which is very important for the whole injection production process, and the product quality 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: the exhaust piece is characterized in that: said exhaust piece distributed and arranged is in the mold side angular position.
As preferred version, said exhaust piece comprises the exhaust passage, and said die venting device comprises patrix exhaust apparatus and counterdie exhaust apparatus, constitutes the exhaust passage between said patrix exhaust apparatus and the said counterdie exhaust apparatus.
As preferred version, said exhaust passage is the zigzag passage.
Beneficial effect: die venting device provided by the invention; Simple in structure, easy to use, efficient is high, through the big density of mould inside the exhaust piece is set, accelerate in time to discharge 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.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done explanation further.
As shown in Figure 1, the die venting device comprises: exhaust piece 2, exhaust piece 2 distributed and arranged are at position, mould 1 corner.
As preferred version, said exhaust piece 1 comprises the exhaust passage, and said die venting device comprises patrix exhaust apparatus and counterdie exhaust apparatus, constitutes the exhaust passage between said patrix exhaust apparatus and the said counterdie exhaust apparatus; Said exhaust passage is a zigzag passage (not shown).
Die venting device provided by the invention, simple in structure, easy to use, efficient is high, through the big density of mould inside the exhaust piece is set, accelerate in time to discharge the gas of mould inside, 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.
Claims (3)
