Previously, JP-A-58-153705 and JP-A-61-
The invention disclosed in Publication No. 131828 is known, but these methods simply impregnate pressure-resistant cast products or sintered parts with an impregnating liquid by suction or pressurization. There is no control over the degree of impregnating liquid or the amount of impregnating liquid. Therefore, if there is too much impregnating liquid, there will be a large loss of impregnating liquid, and if there is too little, there will be problems such as unimpregnated areas remaining, and it will be impossible to judge whether the impregnation is good or bad. It was hot.

In the present invention, a cast product to be impregnated is fixed in a vacuum container so that only the parts requiring impregnation can be impregnated, and impregnation is performed by injecting an impregnating liquid under pressure into a partial masking chamber formed in the vacuum container. In a partial impregnation device for cast products, a liquid injector is connected to the partial masking chamber, and a fixed amount of impregnating liquid can be detected above and below the liquid injector according to the volume inside the partial masking chamber. It consists of a partial impregnation device for a cast product, which is equipped with an upper limit liquid level detector and a lower limit liquid level detector.
以下図面を参照して本発明の実施例を説明する

断面で示す系統図である。
Embodiments of the present invention will be described below with reference to the drawings, which are partial cross-sectional diagrams of the apparatus for partially impregnating cast products of the present invention.
まず、含浸を施す鋳造品１を、ベース３に形成

をベース３に固設する。このようにしてベース３
とカバー２ａからなる真空容器２内に鋳造品１が
取り付けられ、この真空容器２内には、部分的マ
スキング室８ａと真空室８ｂが画成される。 First, the impregnated part 8 of the cast product 1 to be impregnated is inserted into the recess 3a formed in the base 3 through the seal packing 5, and fixed so as to be in close contact with the seal packing 5. Then cover 2a on base 3
is placed through the seal packing 4, and the cover 2a is
is fixed to base 3. In this way base 3
The casting 1 is installed in a vacuum container 2 comprising a cover 2a and a cover 2a, and a partial masking chamber 8a and a vacuum chamber 8b are defined within the vacuum container 2.
次に、真空弁６，９を開き、真空ポンプ７を働
かせて、真空容器２内を排気し、充分真空になつ
た時点で真空弁９を閉じ、液注器１１に矢印Ａの
圧空をかけ、液注弁１２を開いて部分的マスキン
グ室８ａに含浸液を加圧注入する。 Next, open the vacuum valves 6 and 9, operate the vacuum pump 7 to evacuate the inside of the vacuum container 2, close the vacuum valve 9 when a sufficient vacuum is reached, and apply compressed air to the liquid injector 11 in the direction of arrow A. , the liquid injection valve 12 is opened and the impregnating liquid is injected under pressure into the partial masking chamber 8a.

含浸液が液注器１１にもどる。 Therefore, when the appropriate liquid injection time has ended, the compressed air A is released from the pressurizing valve 13 of the liquid injector 11, the vacuum valve 6 is closed, the vacuum valve 9 is opened, and outside air is introduced from the open port of the vacuum valve 6 to create a vacuum. By returning the inside of the container 2 to atmospheric pressure, the impregnating liquid inside the partial masking chamber 8a returns to the liquid filler 11.
その際、加圧注入によつて減少した含浸液部分
だけ、貯槽１４から供給弁１５を開いて含浸液を
追加して次回用に準備する。 At this time, the supply valve 15 is opened to add impregnating liquid from the storage tank 14 to only the portion of the impregnating liquid that has been reduced by the pressurized injection, and the impregnating liquid is prepared for the next use.

１の不良の確認が出来る。 Furthermore, the upper and lower limits of the liquid feeder 11 are equipped with one liquid level sensor 16, 17, respectively, and the upper limit liquid level sensor 16 is controlled by opening and closing the supply valve 15 via the control section. The supply of impregnating liquid from the storage tank 14 is controlled. The lower limit liquid level detector 17 controls the supply of impregnating liquid to the partial masking chamber 8a for impregnating the portion 8 of the cast product 1 that requires impregnation by opening and closing the liquid injection valve 12 via the control unit. By controlling the method, it is possible to check whether the impregnating liquid penetrates the cast product 1 and flows out when there is a large cavity in the cast product 1, and to confirm whether the cast product 1 is defective at the same time.

の良否の判定をすることができる。 That is, by providing the liquid level detectors 16 and 17 above and below the liquid feeder 11, which indicate a certain amount of impregnating liquid according to the volume of the partial masking chamber 8a, as described above, the partial masking chamber 8a can be completely masked. It is possible to detect whether a certain amount of impregnating liquid is injected into 8a, and when the impregnating liquid falls below the lower limit liquid level sensor 17, the loss of impregnating liquid can be prevented by stopping pressurized injection. In addition to preventing this, the liquid level detector 17
Casting product 1 to be impregnated by, for example, turning on an alarm lamp via the control unit in response to a signal from
It is possible to judge the quality of the product.
従つて、上記の上下限の液面感知器１６，１７
の間に入つている含浸漬量を常に一定にすること
が重要になる。 Therefore, the upper and lower limits of the liquid level sensors 16, 17
It is important to always keep the amount of impregnation constant.

浸液を排出し、新しい含浸液に替えられる。 As described above, by partially masking the area requiring impregnation to form the partial masking chamber 8a and injecting the impregnating liquid into this, the amount of impregnating liquid can be reduced.
The storage tank 14 can also be made smaller and the impregnating liquid can be drained and replaced with fresh impregnating liquid before its pot life.
その結果、含浸液との接触面積が減るので、含
浸液の付着消費量が減り、併せて洗滌水処理を減
らすことができる。 As a result, since the contact area with the impregnating liquid is reduced, the amount of adhesion and consumption of the impregnating liquid is reduced, and at the same time, the amount of washing water treatment can be reduced.

In the present invention, since liquid level detectors are provided at the top and bottom of the liquid feeder, it is possible to supply a fixed amount of impregnating liquid according to the capacity inside the partial masking chamber, and it is possible to There is no loss and no unimpregnated areas remain due to too little impregnating liquid. For this purpose, partial impregnation of cast products with stable quality can be performed. In addition, if the cast product has large pores that are defective, the impregnating liquid under pressure leaks significantly from the large pores, and this can be detected.
