Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a spray device used for coating a mold of a die casting machine or the like with a release agent and for cleaning air blow.

[0002]

[Prior Art]

 In a conventional spray device used in a die casting machine, as shown in FIGS. 7 to 9, a nozzle head 8'is formed of an annular pipe, and the nozzle head 8'projects to both sides along the nozzle head 8 '. Thus, the nozzle 20 'was integrally provided (Japanese Utility Model Laid-Open No. 59-25346).

[0003]

[Problems to be solved by the device]

 It is necessary to replace the mold depending on the product, but at the same time, it is preferable to use a nozzle having an arrangement and orientation corresponding to this for cleaning the mold used.

However, in the conventional spray apparatus, since the nozzle 20 'is integrally provided in the annular nozzle head 8', the degree of freedom of the nozzle arrangement is small and the nozzle must be replaced for each nozzle head 8 '. Therefore, it is difficult to handle them easily and quickly. In addition, since it is necessary to prepare a spray device suitable for each mold used, a large storage space is required and the equipment cost is high. In addition, since the nozzle head 8'has an integrated piping structure, the inside of the nozzle head cannot be cleaned, and the nozzle is likely to be clogged with a release agent, which necessitates frequent maintenance of the nozzle 20 '. I couldn't escape.

Therefore, the present invention has been made to solve the above-mentioned problems, and a spray device that can manufacture, store, and replace only the nozzle portion, not the entire nozzle head, and can easily clean the inside of the nozzle head. The purpose is to provide.

[0006]

[Means for Solving the Problems]

 The spray device of the present invention is a spray device equipped with a nozzle head that can be inserted and removed between a fixed mold and a movable mold of a molding machine. A nozzle panel that covers both side openings of the nozzle head body that opens to the side is detachably attached to the nozzle body, and the nozzle body is configured by the nozzle body and the nozzle panel. A fluid reservoir communicating with the supply hose connected to the nozzle head main body is formed inside the nozzle head main body by removing the nozzle panel.

[0007]

[Action]

 The mold release agent or air supplied from the fluid supply source via the supply hose enters the fluid reservoir in the nozzle head and is filled, and then the fixed side mold and the movable side are moved from the nozzles provided on the nozzle panels on both sides. Sprayed onto the mold.

Further, by removing the nozzle panel that covers the double-sided openings of the nozzle head body, the fluid reservoir in the nozzle head can be cleaned through the double-sided openings of the nozzle head body.

When it is necessary to change the nozzle arrangement pattern by exchanging the mold, a nozzle panel having a new nozzle arranged by another arrangement pattern instead of the nozzle panel having the nozzle of the current arrangement pattern Install on both sides of the nozzle head body and cover the opening. In other words, only the nozzle section (nozzle panel) needs to be replaced, not the entire nozzle head.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows the entire spraying device, FIGS. 2 and 3 show a connecting structure of a nozzle head body and a nozzle panel and a nozzle mounting structure, and FIGS. 4 and 5 show a nozzle head body.

In FIG. 1, reference numeral 1 denotes a fixed platen having a fixed mold 2 mounted thereon, and 3 denotes a movable platen having a movable mold 4 mounted thereon, which are arranged to face each other. Then, the movable platen 3 is moved forward and backward with respect to the fixed platen 1 by the mold clamping device so that the fixed side mold 2 and the movable side mold 4 can be opened and closed.

Reference numeral 5 denotes a link-type lifting mechanism. One end of the lifting mechanism 5 is pivotally attached to a stand 6 installed on the fixed platen 1 of the molding machine so as to be vertically tiltable, and A suspension 7 is provided at the other end.

Reference numeral 8 denotes a nozzle head, which is attached to and suspended from the tip portion (suspension body 7) of the elevating mechanism 5.

Then, the nozzle head 8 can be inserted into and removed from the stationary mold 2 and the movable mold 4 in the mold open state by the drive device built in the stand 6 via the elevating mechanism 5. There is.

As shown in FIGS. 2 to 5, the nozzle head 8 is an assembly box type, and has a rectangular frame-shaped nozzle head main body 9 that is open on both surface sides facing the fixed side mold 2 and the movable side mold 4. The nozzle head body 9 is composed of a detachable nozzle panel 10 which covers both opening portions of the nozzle head body 9.

Bolt through holes 11 and 12 corresponding to each other are provided at intervals around the nozzle head main body 9 and the peripheral portion of the nozzle panel 10 that abuts on the end surface of the nozzle head main body 9.

The nozzle head main body 9 and the nozzle panels 10 arranged on both sides of the nozzle head main body 9 are integrally fastened together by bolts 13 and nuts 14 which penetrate through the nozzle head main body 9 through bolt through holes 11 and 12, and at the same time, the nozzle head main body 9 A packing 15 is connected between the abutting surfaces of the nozzle 9 and the nozzle panel 10.

As a result, a fluid reservoir 16 is formed inside the nozzle head 8 so that it can be opened on both sides of the nozzle head body 9 by removing the nozzle panel 10.

The fluid reservoir 16 is provided so as to be supported by the lifting mechanism 5 and communicates with a supply hose 17 connected to the nozzle head body 9.

Rails 18 are stretched outside the upper and lower ends of the nozzle head body 9 so that the nozzle panel 10 can be easily bolted to the nozzle head body 9 and temporarily held, and between the upper and lower rails 18. The nozzle panel 10 can be slidably engaged from one end side.

A plurality of nozzle mounting holes 19 are formed in the nozzle panel 10 so as to face both side openings of the nozzle head body 9, and each of the holes 19 has a nozzle 20 protruding from the outer surface of the nozzle panel 10. Is detachably screwed.

Although the present embodiment is an example in which the nozzle head 8 is an assembly box type, the nozzle head main body is composed of inner and outer rectangular frames connected to each other, and its both-side openings are covered with the nozzle panel. It may be an assembled pipe type. It goes without saying that the assembly box type is more suitable because it has a greater degree of freedom in the arrangement and orientation of the nozzles 20.

Next, the operation of the spray device configured as described above will be described.

After the elevating mechanism 5 is tilted downward by the driving device in the stand 6 to insert and arrange the nozzle head 8 between the fixed-side mold 2 and the movable-side mold 4 in the mold open state, the supply hose 17 When the release agent or air is supplied from the fluid supply source via the supply source, the release agent or air enters the fluid reservoir 16 in the nozzle head 8 from the supply hose 17 and fills the nozzle panel 10 on both sides. Spraying is performed from the provided nozzle 20 toward the fixed mold 2 and the movable mold 4. Therefore, a release agent is applied to the fixed-side mold 2 and the movable-side mold 4, or the fixed-side mold 2 and the movable-side mold 4 are cleaned by air blow.

During use, the nozzle head 8 has a divided structure of the nozzle head main body 9 and the nozzle panel 10, but the packing 15 interposed between the abutting surfaces of the nozzle head main body 9 and the nozzle panel 10 allows a release agent or air to be released. There is no leakage.

Next, when the arrangement pattern of the nozzles 20 is changed from that shown in FIG. 1 to that shown in FIG. 6 due to the necessity of exchanging the used mold, first loosen the nuts 14 from the bolts 13 and remove them. After the bolt 13 is pulled out from the bolt through holes 11 and 12 of the nozzle head body 9 and the nozzle panel 10, the nozzle panel 10 covering the both-side openings of the nozzle head body 9 is removed. In this state, the fluid reservoir 16 in the nozzle head 8 is cleaned through the openings on both sides of the nozzle head body 9. When replacing with the nozzle panel 10 having the new nozzle 20 shown in FIG. 6, the new nozzle 20 is replaced with the nozzle panel 10 shown in FIG. 6 is attached to both sides of the nozzle head body 9 and the opening is covered.
