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 such as Gui Cast A. (Conventional problem) Conventionally, this kind of #! ! ! ! The agent spraying device is complicated because it requires one mold release agent hose and one air hose for each wood nozzle, and it takes a lot of effort to replace the nozzles. Also, recently, Jikko Sho 49-2323
No. 3 is known, in which a hose and a nozzle are made into a block and attached to a distribution stand. However, even with this, it is necessary to replace one nozzle at a time, and each requires an independent air conduit and a release agent conduit, and the configuration of the spray machine that serves as the nozzle is complicated and large. This made it difficult to apply the coating uniformly to molds with complex shapes or large molds.

In addition, there are devices such as Utility Model Application Publication No. 54-7213 in which the number of conduits is reduced and the nozzles themselves can be removed early; however, since there are usually a large number of nozzles, it is troublesome and time-consuming to remove all the nozzles. Therefore, it is not possible to eliminate the above-mentioned drawbacks.

(Objective of the Invention) Therefore, the present invention provides an easy-to-handle lmff1 agent spraying device that can eliminate the above-mentioned drawback 1 and can replace a large number of nozzles at once.

(Example) The details of the present invention will be explained below with reference to illustrated embodiments.

In the apparatus of this example shown in FIGS. 1 to 4, reference numeral 1 denotes a fixed leg installed on a fixed guide plate, and 2 a rotary cylinder, which is attached to the fixed leg 1 so as to be movable up and down. 3 is a mechanism for moving the base 4 back and forth, and is operated by rotating its handle 3a.

Reference numeral 5 indicates a cylinder for raising and lowering the nozzle mounting base 6, 7 indicates a supply pipe for mold release agent fed from a pressure pump, 8 indicates a blowing air pipe for supplying compressed air from a pressure machine, and 9 indicates switching opening/closing from the pressure NJa. blow-off air pipe for supplying compressed air through a valve, 1
0 is a component discharge pipe.

Then, a mold release agent supply pipe 7 and a blowing air pipe 9 are connected to one side of the nozzle mounting base 6, and these pipes 7 are connected via a solenoid valve 11.
, 9 is formed (
(See Fig. 3), and the other side of the nozzle mount is connected to a blowing air pipe 8 and a chemical agent discharge pipe IO, and a blowing air passage 6b and a chemical agent discharge passage 6c communicating with these are formed (
Note that these passages 6a, 6b, and 6c are all opened in the mounting surface of the nozzle holder Sa of the nozzle mount S (see FIG. 4). Nozzle unit y) S consists of a nozzle holder Sa and a large number of nozzles sb, and the nozzle holder Sa forms a mold release agent conduit Sc that communicates the mold release agent supply passage 6a and the composition discharge passage 6c in the mounting base 6 inside. At the same time, an air guide path Sd communicating with the blowing air passage 6b is formed on the outer periphery of the guide path Sc. In addition, the respective copper pipe conduits Se and Sn branched from the respective conduits Sc and Sd are held in holders Sa.
is fixed to the lower part of the nozzle sb to form the nozzle sb (see Fig. 4), and a dovetail-shaped engagement groove 6d is formed at the lower part of the mounting surface of the nozzle mounting base 6, and above the engagement groove 6d. The holding member 12 is attached to the mounting base 6 by the port 14 via the washer 13.
It sticks to. The holding member 12 is engaged with the mounting base 6 so that it can move back and forth depending on the tightening state of the port 14, and a sloped surface 12a as shown in FIG. It is formed into a shaped retaining portion 6e. Therefore, the rear part of the holder Sa is formed into an inclined engagement mounting part Sm so that the holder Sa can be inserted along the engagement groove 6d and the engagement part 6e (see Fig. 3). It is fixed to the stand 6. Reference numeral 16 denotes an O-ring, which communicates the passage of the mounting base 6 with the passage of the holder Sa in a sealed state. 17 is a guide member equipped with a limit switch, and 18 is a limit switch for vertical positioning.

When using this example configured in this way, first loosen the port 14 to increase the distance between the engaging parts 6e, and then move the mounting part Sm of the nozzle holder Sa to the engaging groove 6d and the engaging part 6e. 6
After inserting along line e (see line a in Figure 2), Porto 1
4 and press the attachment part Sm with the presser material 12. This ensures that the holder Sa is held as shown in Figure 2 and will not come off. In this state, release agent is applied as shown in Figure 4. As a result of the supply passage 6a and the fiffi agent passage Se being electrically connected, and the blowing air passage 6b and the air passage Sd being electrically connected, the g1 plate agent is sprayed from the nozzle tip by driving the compressor that supplies the mold release agent and compressed air. It will be done. At this time, the on-off valves of the chemical agent discharge pipe 10 and the blow-off air pipe 9 are closed.

The special feature of this example configured in this way is as follows. First of all, since the nozzles are an integrated unit, all the nozzles can be replaced simply by replacing the holder Sa like a cartridge system. In particular, since a large number of nozzles can be replaced at once, it is less time-consuming compared to the conventional method, which involves removing piping one by one.

Second, air hoses for each nozzle.

Since a mold release agent hose is not required, a large number of nozzles can be arranged in parallel at narrow intervals, and even large molds can be uniformly coated with mold release agent. Also, since each hose is not required, the appearance can be maintained in a good condition.

Thirdly, when spraying to the n feeding mold, each nozzle sb
Since spraying can be bent to suit the surface, it is easy to apply the g1 base agent to molds with complex shapes (see gS5B), and for this reason, the length of the nozzle sb is made long. Note that the material of the nozzle pipe does not matter as long as it can be deformed.

Therefore, if the nozzle of the exchangeable nozzle unit is bent in advance according to the mold, a nozzle that matches the mold can be obtained simply by exchanging the nozzle.

Fourthly, after spraying is finished, the switching valve opens the component discharge pipe 10, and with the TFFI agent supply pipe 7 closed, the blow-off air pipe 9 is opened to supply compressed air to the mold release agent supply passages 6a, j. ! The l-type agent is supplied to the L-type agent conduit Sc. As a result, the mold release agent remaining in the pipes, passages, and conduits is returned to the negative agent tank from the discharge pipe 10 through the agent discharge path 6C, so that there is no loss of negative agent and it can be used efficiently. (See the imaginary line in Figure 4), and since the GL type agent in the nozzle pipe is also sprayed from the nozzle and emptied, the GL type agent does not fall from the nozzle when not in use (Structure of the Invention) This example is as described above. However, the present invention is not limited thereto. For example, the shapes of the nozzle mount and nozzle holder, and the connection structure between the mount and the holder are also suitable. In addition, regardless of the configuration of the nozzle, a single tube ↑ that passes the Jw type agent mixed with air is also suitable.The installation of the nozzle to the holder does not matter whether it is offset or not.
The configuration and shape of the L-type agent passage are arbitrary, and in this example, a GL-type agent supply passage and a blowing air passage were formed in the nozzle mounting base and communicated with the respective channels in the nozzle holder. If the supply path for the mixed R1 type agent is formed in the nozzle mount, the mechanical agent path formed in the holder is one drop.
Alternatively, after the nozzle holder is attached to the nozzle mounting base, the supply pipe of the release agent supply mechanism may be directly attached to the nozzle holder, and the nozzle holder may be configured to communicate with the agent passage. What is a nozzle holder comprising a large number of nozzles, which has a glffi agent supply mechanism consisting of a supply amount and a compressed air supply device, and includes a moving means capable of displacing the position of the nozzles? The holder is removably attached to a nozzle mounting base provided on the t91 main body, and the holder is provided with a release agent passage that connects and communicates the nozzle with the supply pipe or supply path of the release agent supply mechanism. g
This is an ag agent spraying device.

(Effects of the Invention) Therefore, according to the present invention, a large number of nozzles can be easily replaced at once by simply replacing the nozzle holder. Since there is no need for A-type agent or air hoses or piping, a large number of nozzles can be lined up at close intervals, making it possible to uniformly apply negative agent to the entire mold even in complex-shaped molds or large molds. It has advantages such as simple structure, easy handling, low cost manufacturing, and good appearance.
