Description

Spray head device of metal die casting machine capable of uniform spraying

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

The existing metal die-casting machine needs to spray the release liquid onto a male mold and a female mold before the die-casting operation, so that the casting can be smoothly demolded. The release liquid is sprayed through a spray device, which has a large number of spray heads in parallel, and these spray heads are nozzles formed by bending copper pipes. After the die-casting is completed and the casting is taken out, the spray device will be driven between the male mold and the female mold, and the spray liquid (ie, a mixture of water and mold release liquid) is sprayed by the spray pipes to allow the mold release liquid to adhere On the surfaces of the male mold and the female mold, when the mold is closed, the next round of metal die casting process is continued.

After the metal die-casting, the mold temperature is extremely high. If spraying the release liquid directly on it, there is often a problem of poor adhesion. Therefore, it is necessary to cool the mold before spraying the release liquid. The existing spray device directly uses the release liquid as the cooling liquid for cooling the mold. The reason is that the spray device can only spray the release liquid with high-pressure gas from all the spray tubes at a time during the spray operation. Water or release liquid is sprayed, and the existing metal die casting machine uses this nozzle to cool the mold, so in operation, a certain amount of release liquid is sprayed to cool the mold, and then only Spraying the release fluid required for die casting, as a result, the release fluid is wasted and is more time-consuming in the manufacturing process.

In order to solve the above-mentioned deficiencies, the applicant has applied for and obtained the TW certificate No. I583463 "Atomizer applicable to metal die-casting machine and nozzle device with the atomizer" patent case, the nozzle device includes a nozzle and a sprayer, the nozzle includes A base body and a nozzle unit provided on the base body, the sprayer is installed on the spray head. The sprayer is connected with a release liquid source, a water source and a gas source. The sprayer includes a body and two valve parts. The body includes a release liquid channel connected to the release liquid source, a water channel connected to the water source, an air channel connected to the gas source, and a mixing chamber. The release liquid channel, the water channel and the air channel communicate with the mixing chamber. The mixing chamber has a spout that communicates with the outside world. The valves are installed in the body, and are respectively arranged in the release liquid channel and the water channel, and can respectively open and close the release liquid channel and the water channel.

Although the TW certificate No. I583463 patent case allows the nozzle to spray water vapor, release liquid, or a mixture of the two through the sprayer, it can solve the problem of waste of release liquid, but it still has the following problems:

1. When the male mold and the female mold are replaced, the spray tubes of these nozzles cannot be removed from the corresponding body (because it takes time and the accuracy of the corresponding male and female molds needs to be adjusted when installing after disassembly), and It is necessary to dismantle the entire set of nozzles in order to achieve the purpose of faster replacement. However, the difference between the molds to be replaced may only be partial. Disassembling the entire group of nozzles takes too much time and affects the production capacity.

2. The air outlet of the atomizer directly corresponds to the outlet of the spray tube. The atomized release liquid may still be directly sprayed out. The atomization amount of each atomization tube may still not be very uniform. , Making the uniformity of the air and release liquid sprayed through the nozzle unit of the spray head insufficient, and the atomization effect is not good.

3. For the side modules and the deep holes provided in the male mold, the female mold, the side modules, etc., a better spraying effect of the release liquid cannot be produced.
