Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a mold release agent spraying device for applying a mold release agent to a mold so that a casting can be easily removed from a casting mold in a die casting machine, etc. It is something.

(Prior art) Conventionally, this type of mold release agent spraying device requires one spray pipe and one air blow pipe for each nozzle, which makes the mechanism complicated and requires nozzle replacement. This required a great deal of effort.

In order to solve the above-mentioned problems, Japanese Utility Model Application No. 56-141871 discloses a system in which the pipe and nozzle are made into blocks and mounted on a distribution stand.

However, because the mold release agent supply section is only at the side end of the spray pipes arranged in parallel, there is a difference in the amount of spray from the pipes near and far from the supply section, making it difficult to coat the mold. There was a problem that uneven spraying occurred.

In addition, since a single pipe serves as both the spray and the air blow, there is a drawback that the mold release agent remaining in the spray pipe is sprayed together with the air blow after the casting is removed from the mold. Furthermore, since the mold release agent was atomized inside the spray pipe, it was difficult to atomize it into a fine and uniform atomization.

(Problem to be solved by the invention) The problem to be solved by the invention is to equalize the amount of mold release agent sprayed from the spray pipe and to evenly atomize the mold release agent. The purpose is to eliminate unevenness and prevent the release agent from being sprayed during air blowing.

(Means for solving the problem) The technical means for solving the above problem is to provide a mixing atomizer on both the left and right sides of the manifold, and to recess a spray distribution chamber and an air blow distribution chamber on the bottom surface of the atomizer. A pipe cassette including a plurality of spray pipes and air blow pipes covering both distribution chambers is removably provided below the distribution chambers, and mixing atomizers are provided on both left and right sides of the spray distribution chamber and on both the left and right sides. and an air supply passage communicating between the air blowing distribution chamber and the mixing atomizer.

(Function) The mold release agent mixed in the mixing atomizer is supplied from both sides to the spray distribution chamber through the left and right mold release agent supply passages, and is sprayed from the air blow pipe, and the air blow is passed through the air supply passage. It is then sprayed onto the air blow pipe.

(Example) An embodiment of the present invention will be described with reference to the drawings.

The mold release agent spraying device A of the present invention is provided with mixing atomizers on the top surfaces of both sides of a manifold 1, and a pipe cassette 3 equipped with a spray pipe 4 and an air blow pipe 5 on the bottom surface of the manifold 1, which can be freely attached and detached. It is something that

The manifold 1 is a horizontally elongated block body, and has mixing atomizers 2 provided on both sides of its upper surface, and a release agent supply passage 6 and an air supply passage 7 provided therein.

The mixing atomizer 2 is for atomizing the mold release agent and connects the mold release agent supply pipe 8 and the air supply pipe 9, respectively.

The spray distribution chamber 10 is a long groove recessed in the center of the lower surface of the manifold 1, and the spray pipe 4 is attached to the lower side of the distribution chamber 10 to distribute the atomized release agent to the spray pipe 4. .

The air blow distribution chamber 11 is recessed in parallel with the spray distribution chamber 10, is a long groove with a width approximately half that of the spray distribution chamber 10, and is for distributing air to the air blow pipe 5. be.

The mold release agent supply passage 6 is for supplying the mold release agent mixed in atomized form by the mixing atomizer 2 to the spray distribution chamber 10, and connects the left and right mixing atomizers 2 and the left and right sides of the spray distribution chamber 10. The mold release agent is supplied from both sides of the distribution chamber 10 through communication, and the spray pipe 4 of the pipe cassette 3
sprayed evenly.

The air supply passage 7 is for supplying air to the air blowing distribution chamber 11, and communicates one of the left and right mixing atomizers 2 with the distribution chamber 11 to allow air to be blown out from the air blowing pipe 5 of the pipe cassette 3. Ru.

As shown in FIG. 7, the pipe cassette 3 includes a flat plate 3a having a size that covers the mold release agent supply passage 6 and the air supply passage 7, and a spray pipe 4 and an air blow pipe 5 arranged in parallel at appropriate intervals. and is detachably attached to the pipe cassette mounting base 3b using a cartridge method.

Moreover, the spray pipe 4 and the air blow pipe 5 are made of copper pipes or flexible pipes that are flexible and whose injection ports can be bent in the desired direction. It may be removably attached by brazing or using fittings.

In addition, when attaching the mold release agent supply pipe 8 and the air supply pipe 9 to only one side of the left and right mixing atomizers 2, the manifold 1 has a mold release agent communication passage 12 and an air communication passage 13 that communicate the left and right mixing atomizers 2. By installing the mold release agent internally, it is possible to supply the mold release agent mixed in a mist form by the atomizers 2 on both the left and right sides to the spray distribution chamber 10 from both the left and right sides, and to spray it evenly from the spray pipe 4. Can be done.

In this case, the air supply passage 7 is in a closed state, and in the case of air blowing, the air communication passage 13 is closed to perform air blowing.

(Effects of the invention) Since the present invention has the above configuration, it has the following effects.

By supplying the mold release agent to the left and right sides of the mold release agent supply passage from both the left and right sides, the mold release agent is evenly sprayed from the spray pipe, and uneven spraying can be eliminated.

Since the spray pipe and air blow pipe are independent, there is no need to spray the mold release agent together when air blowing, and effective blowing can be performed.

The mold release agent atomized by the mixing atomizer can be sprayed from the pipe, resulting in an even and fine spray.
