〔産業上の利用分野〕
本考案は、主に鋳造用のシエル中子金型に適用
して最適な金型の排気装置に関する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a mold exhaust system that is suitable for application mainly to shell core molds for casting.
従来、この種排気装置を適用した中子金型とし

Conventionally, there have been core molds to which this type of exhaust device is applied, as shown in FIGS. 5 and 6. That is, in the figure, A is a mold for molding the core,
Consists of upper mold B and lower mold C, both upper and lower molds B and C
A cavity D is formed by abutting the mating surfaces of the two. E is a blowhole for injecting shell sand into the cavity D.
そこで、上型Ｂと下型Ｃとを当接してこれを約
300℃に加熱し、前記ブローホールＥからキヤビ
テイＤ内にシエル砂を注入するのであるが、シエ
ル砂の砂粒の外周には、硬化材（レジン）が塗布

に多数の中子金型Ａを設置した鋳造工場では工場
内外の環境問題となつている。 Therefore, the upper mold B and the lower mold C are brought into contact and this is approximately
The shell sand is heated to 300°C and injected into the cavity D from the blowhole E, but since a hardening agent (resin) is coated on the outer periphery of the sand grains of the shell sand, this hardening agent is heated to 300℃. Core mold A
It burns as soon as it touches it, producing a large amount of smoke and odor. Most of this smoke and odor is emitted to the outside from the unsealed mating surfaces of upper mold B and lower mold C, and in order to prevent this from accumulating inside the factory, a particularly large number of core molds A were installed. Foundries have become an environmental problem both inside and outside the factory.
そこで、このような問題を解決するために、中
子金型Ａの全体をフードＦで囲み、フードＦ内に
充満した煙や臭気を図示しない吸引機によりダク
トＧを介して吸引している。 Therefore, in order to solve this problem, the entire core mold A is surrounded by a hood F, and smoke and odor filling the hood F are sucked out through a duct G by a suction device (not shown).
また、後述するように、本考案とは異なるが、
第７図に示すように、型合せによりキヤビテイ部

ヤビテイ部Ｊと連通路Ｌとが連通されるように形
成したものがある（実開昭58−57361号公報）。 In addition, as described later, although it is different from the present invention,
As shown in FIG. 7, an extrusion pin M is provided in one of the upper mold H and lower mold I, which constitute the cavity part J by mold matching, with a communication path L through which the outside and the mold mating surface K communicate with each other. There is a type in which the mold is slidably inserted and an air vent groove N is formed in at least one of the molding surfaces K so that the cavity J and the communication path L communicate with each other (see Utility Model Publication No. 58-57361). ).

がある。 Furthermore, as disclosed in Japanese Utility Model Application Publication No. 60-166448, an air vent hole is provided in the upper wall of the upper mold, and air from an air supply device is passed through a connecting passage communicating with the air vent hole. There is a mold casting apparatus that has an opening in a ventilate part interposed in an air passage.
しかし、第５図及び第６図に示す従来例のもの

ある。
However, in the conventional example shown in Figs. 5 and 6, the entire core mold A is covered with a hood F, which requires a large hood F and a suction machine with a large air volume, and requires a large installation space. Space is also required, and equipment costs also increase. Furthermore, since the entire core mold A is covered with the hood F, there is a problem in that workability is significantly reduced.
一方、第７図の従来例は、鋳造時にキヤビテイ

排除は全く考慮されていない。 On the other hand, in the conventional example shown in Fig. 7, in order to prevent the air generated in the cavity J during casting from remaining in the product after molding and causing cavities and nests, resulting in product defects, The aim was to eliminate harmful smoke and odors generated during casting, and no consideration was given to eliminating harmful smoke and odors generated during casting.
さらに、実開昭60−166448号公報で開示されて

る。 Furthermore, the device disclosed and devised in Japanese Utility Model Application Publication No. 166448/1983 has air vent holes in the upper mold part, which is the part where the most smoke and odor leak to the outside. Located far from the mating surface.
Therefore, there is a problem in terms of exhaust efficiency, and it is thought that there is also a problem in that it interferes with the separation work of the upper mold from the lower mold and is inefficient.

The present invention was developed in order to solve the above-mentioned conventional problems, and aims to provide a device that is small, does not impair workability, and has a large exhaust effect. The gist of this is that a gas escape groove is provided around the mating surface of either the upper mold or the lower mold, the exhaust port is set in one direction of the mating surface, and furthermore, a gas escape groove is provided along the gas escape groove. A sealing material protruding from the mating surface is attached to the outside of the mating surface, and a sealing groove is formed on the other mating surface to fit with the protrusion of the sealing material. The mold exhaust system is characterized by having been installed.

下金型２の合せ面４を当接することによりキヤビ
テイ５が形成される。 In the above drawing, 1 is a mold for molding the core, which is composed of an upper mold 2 and a lower mold 3, and a cavity 5 is formed by abutting the mating surfaces 4 of the upper mold 1 and the lower mold 2. It is formed.
上記の下金型２の合せ面４には、キヤビテイ５

このガス逃げ溝４の一部は下金型２の一側面に形
成した開口部７を介して外部と連通している。 There is a cavity 5 on the mating surface 4 of the lower mold 2 above.
A gas escape groove 6 is formed along the outer periphery of the
A portion of this gas escape groove 4 communicates with the outside via an opening 7 formed on one side of the lower mold 2.

１０が形成されている。 Further, a seal groove 8 is formed on the mating surface 4 of the lower mold 2 around the outer periphery of the gas escape groove 6, and this seal groove 8 is filled with a sealing material 9.
The upper part of the sealing material 9 is located between the mating surfaces 4 and 2 of the lower mold 2.
The mating surface 4 of the upper mold 1 protrudes by about mm.
A seal groove 10 is formed in which the upper part of the seal material 9 described above fits.

間に燃焼し、多量の煙と臭気が発生する。 Therefore, the upper mold 2 and the lower mold 3 are brought into contact with each other and heated to approximately 300° C., and at the same time, a suction machine (not shown) is driven to perform suction operation from the opening 7 through the duct 12. . Then, shell sand is injected into the cavity 5 from the blowhole 11. At this time, the hardening agent (resin) applied to the outer periphery of the sand grains of the shell sand touches the hot core mold 1. It will burn and produce a lot of smoke and odor.

気は合せ面４から外部に放出されず、その内側に
あつて負圧となつているガス逃げ溝６を流通し、
開口部７からダクト１２で吸引される。 However, since the area around the mating surface 4 of the upper mold 2 and the lower mold 3 is sealed with a sealing material 9, smoke and odor are not released from the mating surface 4 to the outside, but remain inside and have negative effects. The gas flows through the pressure relief groove 6,
It is sucked through the opening 7 through the duct 12.

も効果がある。 In the above embodiment, the gas escape groove 6 and the sealing material 9 are molded in the lower mold 2, but it goes without saying that they may be formed in the upper mold 1. In addition, although the mold 1 of the embodiment was explained as being for molding a core, it is of course possible to apply it to a general-purpose mold, and furthermore, if the suction power of the suction machine is increased, smoke and odor can be removed. Not only can the air be exhausted, but also the air generated within the cavity 5 can be sucked in, which is effective in improving product quality.
