Abstract
The utility model discloses a mould exhausting device. The mould exhausting device comprises exhausting blocks. The mould exhausting device is characterized in that the exhausting blocks are distributed at corners of a mould; each exhausting block comprises an exhausting channel; the mould exhausting device consists of an upper mould exhausting device and a lower mould exhausting device; an exhausting channel is formed between the upper mould exhausting device and the lower mould exhausting device; and the exhausting channel is a sawtooth shaped channel. The mould exhausting device provided by the utility model is simple in structure, convenient to use and high in efficiency; the exhausting blocks are highly and densely arranged in the mould, thereby gas in the mould is sped up to be exhausted timely; and the mould exhausting device plays an important role in the whole injection molding production, and improves the quantity of a product.
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: exhaust block is characterized in that: described exhaust block distributes and is arranged on the mold side angular position.
As preferred version, described exhaust block comprises the exhaust passage, and described die venting device comprises patrix exhaust apparatus and counterdie exhaust apparatus, consists of the exhaust passage between described patrix exhaust apparatus and the described counterdie exhaust apparatus.
As preferred version, described exhaust passage is the zigzag passage.
Beneficial effect: the die venting device that the utility model provides, simple in structure, easy to use, efficient is high, by the exhaust block that arranges in the large density of mould inside, accelerates 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 structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the die venting device comprises: exhaust block 2, exhaust block 2 distributes and is arranged on position, mould 1 corner.
As preferred version, described exhaust block 1 comprises the exhaust passage, and described die venting device comprises patrix exhaust apparatus and counterdie exhaust apparatus, consists of the exhaust passage between described patrix exhaust apparatus and the described counterdie exhaust apparatus; Described exhaust passage is zigzag passage (not shown).
The die venting device that the utility model provides, simple in structure, easy to use, efficient is high, by the exhaust block that arranges in the large density of mould inside, accelerates 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 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.
