Abstract

The utility model discloses a combustion chamber. The combustion chamber comprises a support and a box body mounted on the support, wherein a combustion engine is mounted on one side of the box body; shift gates are respectively arranged at the two ends of the box body; an upper track and a lower track are arranged on the support; first rolling wheels matched with the upper track are mounted above the shift gates; second rolling wheels matched with the lower track are mounted below the shift gates; racks are mounted on the shift gates; driving devices are mounted on the support; gears matched with the racks are mounted on output shafts of the driving devices; a pipeline is mounted on the other side of the box body; a circulating device capable of enabling air to circulate is mounted on the pipeline; and the two ends of the pipeline are respectively communicated with the upper end and the lower end of the box body, so that hot air at the upper end in the box body can be blown to the lower end in the box body through the circulating fan, and a die in the box body can be evenly heated, thereby avoiding overlarge wall thickness errors of manufactured products.

Description

The combustion chamber

Technical field

The utility model relates to a kind of combustion chamber.

Background technology

The processing and forming technology of plastics and composite thereof has a variety of, except people common extrude, the technology such as injection, blow molding, rotational moulding also is a kind of processing method of plastic products.

Rotation molding claim again to revolve mould, rotational forming, rotational molding, rotational casting, rotation-formed etc.Roll moulding shaping technology is earlier plastic raw materials to be added in the mould; Then mould is pushed in the combustion chamber, mould constantly rotates and makes it along two vertical axises and heats then, makes the interior plastic raw materials of mould under the effect of gravity and heat energy; Coating, fusion adhere on the whole surface of die cavity equably gradually; Be shaped to needed shape,, obtain goods at last again through cooling and shaping, the demoulding.

Combustion chamber of the prior art generally comprises: support and be installed on the casing on the support, said casing are provided with and can move door with respect to what support moved, and a side of said casing is provided with combustor, during use; Earlier the door that moves on the casing is opened, then mould is pushed casing,, follow the switch on the starting apparatus combustion engine again with the closure of moving on the casing; To heating in the casing, in the process of heating, because hot gas density is littler than air; So hot gas can upwards waft, cold air density is bigger than air, so cold air can be to sinking; Therefore hot gas all concentrates on the top of casing, and cold air all concentrates on the below of casing, and this will cause non-uniform temperature in the casing; The mould inequality of being heated, thus cause final product wall thickness different, even aperture appears.

Therefore, be necessary to provide a kind of combustion chamber that solves the problems of the technologies described above.

The utility model content

The utility model technical problem to be solved is: a kind of mould uniform combustion chamber that is heated that makes is provided.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the combustion chamber, and it comprises: support and be installed on the casing on the support; One side of said casing is equipped with combustor, and the two ends of said casing are respectively equipped with moves door, and said support is provided with and gets on the right track and lower railway; The said top of moving door is equipped with and first roller that gets on the right track and match; The said below of moving door is equipped with second roller that matches with lower railway, and the said door that moves is equipped with tooth bar, and said support is equipped with drive unit; The gear that matches with tooth bar is installed on the output shaft of said drive unit; The opposite side of said casing is equipped with pipeline, and the EGR that makes air circulation is installed on the said pipeline, and the two ends of said pipeline are logical with the upper end and the lower ends of casing respectively.

As a kind of optimized technical scheme, said casing is welded by square tube and two-layer iron plate, is equipped with heat-preservation cotton between the two-layer iron plate and in the square tube.

As a kind of optimized technical scheme, said drive unit is a motor.

As a kind of optimized technical scheme, said EGR is a circulating fan.

As a kind of optimized technical scheme, the said central authorities that move door are provided with circular hole.

The beneficial effect of the utility model is: the opposite side through at said casing is equipped with pipeline, and the EGR that makes air circulation is installed on the said pipeline, and the two ends of said pipeline are logical with the upper end and the lower ends of casing respectively.Thereby can make the hot gas of upper end in the casing blow to the lower end in the casing, the mould in the casing is heated evenly, thereby the product wall thickness deflection that can avoid producing is excessive through circulating fan.

The specific embodiment

See also Fig. 1 and Fig. 3, combustion chamber 100, it comprises: support 1 and be installed on the casing 2 on the support 1; One side of said casing 2 is equipped with combustor 3, and the two ends of said casing 2 are respectively equipped with moves door 20, and said support 1 is provided with and gets on the right track 10 and lower railway 11; Said door 20 the top of moving is equipped with and 10 first rollers 21 that match that get on the right track; The said below of moving door 20 is equipped with second roller 22 that matches with lower railway 11, and the said door 20 that moves is equipped with tooth bar 23, and said support 1 is equipped with drive unit 12; The gear 120 that matches with tooth bar 23 is installed on the output shaft of said drive unit 12; The opposite side of said casing 2 is equipped with pipeline 4, and the EGR 5 that makes air circulation is installed on the said pipeline 4, and the two ends of said pipeline 4 are logical with the upper end and the lower ends of casing 2 respectively.Said casing 2 is welded by square tube 24 and two-layer iron plate 25; Be equipped with heat-preservation cotton between the two-layer iron plate 25 and in the square tube 24; The setting of said heat-preservation cotton can prevent that heat in the combustion chamber is to external diffusion; In this embodiment, said drive unit 12 is a motor, and said EGR 5 is a circulating fan.The said central authorities that move door 20 are provided with circular hole 200.

The operation principle of combustion chamber is: when plastic raw materials is added in the mould, and in the time of need heating mould, starter motor at first; Motor is just changeed, and motor drives through the rack-and-pinion transmission and moves door 20 and shift to two ends from the centre, then disable motor; Mould is pushed in the combustion chamber 100, and then starter motor, make the motor counter-rotating; Motor again through the rack-and-pinion transmission drive move door 20 from two ends to intermediate closed, then through heating in 3 pairs of casings 2 of combustor, in the process of heating; Hot gas is concentrated in the top in the casing 2, thereby causes having the temperature difference between the top and bottom in the casing 2, and circulating fan good this problem that solved is set; The air inlet of circulating fan is connected with the upper end of casing through pipeline, and the air outlet of circulating fan is logical with the lower ends of casing 2 through pipeline 4, thereby makes the hot gas of upper end in the casing 2 blow to the lower end in the casing through circulating fan; Mould in the casing is heated evenly, thereby makes the product that produces have quality preferably.
