Technical Field

The invention relates to a metal die casting machine, in particular to a nozzle device of the metal die casting machine, which can spray uniformly.

Background

When the existing metal die-casting machine is used for die-casting operation, release liquid needs to be sprayed onto a male die and a female die so that a casting can smoothly retreat. The release liquid is sprayed by a spraying device which is provided with a plurality of parallel spray heads, and the spray heads are spray nozzles formed by bending copper pipes. After the die casting is finished and the casting is taken out, the spraying device is driven to be between the male die and the female die, the spraying pipe is used for spraying the release liquid (the mixture of water and the release liquid) so as to enable the release liquid to be attached to the surfaces of the male die and the female die, the die is closed, and the next cycle of metal die casting process is continued.

After carrying out metal die-casting, the mould temperature is high, if directly spray on it with the parting liquid, often adheres to not good problem, consequently need just can spray parting liquid with this mould cooling back earlier. The existing spraying device is directly used for taking the release liquid as the cooling liquid for cooling the die, and the reason is that when the spraying device is used for spraying, the release liquid can only be sprayed out by high-pressure gas in all spraying pipes at one time, and only water can not be sprayed out or the release liquid can not be sprayed out.

Although the application publication No. CN205587628U discloses that the sprayer can selectively spray water vapor, release solution, or a mixture of the two, the problem of waste of the release solution can be solved, but the following problems still exist:

When the male mold and the female mold are replaced, the spray pipe of the spray head cannot be detached from the corresponding body (because the time is spent and the accuracy of the corresponding male mold and female mold needs to be adjusted when the spray pipe is detached and then is mounted), and the whole group of spray heads needs to be detached, so that the purpose of rapid replacement can be achieved.

second, the venthole of atomizer directly corresponds the tub export of spray tube, and what its atomizing came out still probably can be direct has just been spun out, and the atomizing volume of each spray tube probably still can be very even for see through the nozzle unit spun air of this shower nozzle and the degree of consistency from type liquid are not enough, atomization effect is not good.

This separation member 56 is just installed as required, and utilizes separation member 56 installs in this appearance room 542, can reduce this appearance room 542's volume, and can increase the pressure of spouting from type liquid, can reduce from the type liquid and remain in the volume in auxiliary nozzle 55, utilize this separation member 56 top cover to locate this auxiliary spout 418 simultaneously, can block off water and air inflow this appearance room 542, and only spout from type liquid.

For a further understanding of the invention, its role, the technical means employed, and the efficacy attained by its cooperation, the invention is further described and illustrated below, it is believed that the invention will be better understood and appreciated from this description.

As shown in fig. 7 and 8, after the die casting of the metal die casting machine is completed, the step of blowing flocs is completed by using the gas injection pipe 122, and then the main valve element 23' of the main sprayer 20 is operated to open the water channel 214, and water is taken out by the pressure air introduced by the gas channel 219 and sprayed onto the male die 5 and the female die 4 of the metal die casting machine for cooling. Finally, the main valve 23 located on the release liquid channel 213 or (and) the main valve 23' located on the water channel 214 is controlled, so that the release liquid or the mixture of water and the release liquid is taken out and sprayed onto the mold.

as shown in fig. 7 and 11, when the release fluid or the mixture of water and release fluid is introduced into the mixing tank 311 from the main nozzle 218 and the guide hole 113, the cross section of the mixing tank 311, which is communicated with the main nozzle 218 and perpendicular to the main axis L, is a true circle, the perforations 33 are arranged in a staggered manner, and the main nozzles 32 respectively correspond to the perforations 331 and are radially connected to the outer sections 315 of the outer annular surface 313, so that the release fluid or the mixture of water and release fluid introduced into the mixing tank 311 is not directly ejected from the main nozzles 32 but is reformed in the mixing tank 311 and is ejected radially from the mixing tank 311, and the release fluid or the mixture of water and release fluid can be uniformly ejected from each main nozzle 32, thereby generating a uniform spraying effect.

As shown in fig. 9, 10 and 12, in a state where the blocking member 56 is not installed, and during the spraying process of the main sprayer 20 and the main nozzle unit 30, the air nozzle 122 can be used to spray air, and the step of blowing flocs on the male mold 5 and the side mold 6 is completed, and then the auxiliary sprayer 40 is used to cooperate with the corresponding auxiliary nozzle unit 50, and the auxiliary valve 43' of the auxiliary sprayer 40 is controlled to open the water channel 414, and water is taken out by the pressure introduced by the air channel 419 and sprayed to the male mold 5 and the side mold 6 of the metal die casting machine for cooling. And finally, controlling an auxiliary valve 43 on the release liquid channel 413 to take out the release liquid and spray the release liquid onto the female die 4, the male die 5 and the side die block 6, and especially spraying pure release liquid to the part provided with the deep hole 601.

Therefore, for the female mold 4, the male mold 5 or the side mold block 6 provided with the deep hole 601, the auxiliary sprayer 40 and the corresponding auxiliary spray pipe unit 50 are matched with each other, so that the auxiliary spray pipe 55 can be controlled to spray pure release liquid into the deep hole 601 in a single-column manner (without mixing gas and water), the release liquid can easily penetrate into the deep hole 601, and the release liquid can be automatically vaporized due to the high temperature inside the deep hole 601, so that the release liquid can be attached to the wall surface of the deep hole 601, and the deep hole 601 can be improved to generate a better demolding effect.

Furthermore, for the female mold 4, the male mold 5 or the side mold block 6 provided with the deep hole 601, the blocking member 56 can be additionally installed inside the auxiliary base 54 as required, the volume of the accommodating chamber 542 can be reduced, the pressure of the ejected release liquid can be increased, and the amount of the release liquid remaining in the auxiliary nozzle 55 can be reduced.

As shown in fig. 12, by the cooperation between the auxiliary base 54 of the auxiliary nozzle unit 50 and the auxiliary nozzles 55, the cross section of the chamber 542 perpendicular to the auxiliary axis L2 is in a true circle shape, and the connection hole 543 is disposed between the inner port 543' of the inner circumferential surface 541 and the auxiliary axis L2 in an equidistant manner, so that the release fluid or the mixture of water and release fluid introduced into the chamber 542 is not directly sprayed out from the auxiliary nozzles 55, but is reformed in the chamber 542 and then radially sprayed out, and the release fluid or the mixture of water and release fluid can be uniformly sprayed out from each auxiliary nozzle 55, thereby generating a uniform spraying effect.

Therefore, the nozzle device 100 of the metal die casting machine capable of spraying uniformly according to the present invention can produce the following effects:

Firstly, in cooperation with replacement of the male mold 5 and the female mold 4, each main nozzle unit 30 can be independently detached and installed in the seat hole 133 of the seat 13, the main nozzle units 30 are quite easy to detach and replace, and each main nozzle unit 30 can also be independently adjusted for different male molds 5 and female molds 4, so that the productivity can be improved.

Secondly, the mixing grooves 311 of the main nozzles 31 of the main nozzle unit 30 are in a true circle shape in cross section perpendicular to the main axis L, the perforations 33 are arranged in a staggered manner, and the main nozzles 32 correspond to the perforations 331 respectively and are radially connected to the outer sections 315 of the outer annular surface 313, so that the release fluid or the mixture of water and the release fluid can be uniformly sprayed out of each main nozzle 32, and a uniform spraying effect can be generated.

thirdly, by operating the adjusting member 53, the spraying angle of the auxiliary nozzle unit 50 can be manually adjusted, and the specific parts of the male mold 5 and the side mold block 6 can generate a better release liquid spraying effect.

In summary, the nozzle device of the metal die casting machine capable of spraying uniformly according to the present invention can replace different main nozzle units according to the die requirement of the die casting machine, so as to achieve the purpose of spraying uniformly, and can adjust the spraying angle of the auxiliary nozzle unit 50 according to the different die requirements, thereby achieving the purpose of the present invention.
