BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
本実施の形態に係るダイカスト用金型 1は、 第 1型本体 3と、 第 2型本体 5と The die-casting mold 1 according to the present embodiment includes a first mold body 3, a second mold body 5,
、 ホルダ 7と、 冷却手段 9と、 押しピン 1 1とを備えている。 第 1型本体 3及び 第 2型本体 5の間には、 製品形状に応じたキヤビティ 1 3が形成されるようにな つている。 冷却手段 9は、 冷却管 1 5と、 その根元に配置されるベース部 1 7と を備えている。 冷却管 1 5は、 二重管構造になっており、 すなわち、 その軸心部 分に配置され冷却液をキヤビティ 1 3近傍に向けて送り込む供給路 1 9を備え、 供給路 1 9の周囲に同軸的に配置され冷却液がベース部 1 7に向けて戻る環状の 戻り路 2 1を備える。 この冷却管 1 5は、 第 2型本体 5と、 その外側に配置され たホルダ 7とを貫通している。 ベース部 1 7は、 ホルダ 7の外側に配置されてお り、 図示しない冷却液供給源から供給路 1 9に冷却液を送るための冷却液注入口 2 3と、 戻り路 2 1からの冷却液を上記冷却液供給源へと回収するための冷却液 排出口 2 5とを備えている。 冷却液は、 この冷却液排出口 2 5から吸引されるこ とで、 負圧状態を保ちながら冷却管 1 5内を流通する。 また、 押しピン 1 1は、 その長手方向に往復できるように第 2型本体 5及びホルダ 7を貫通しており、 そ の一端は図示しない駆動源に連結され、 他端はキヤビティ 1 3の存在する位置に 到達できるようになつている。 また、 押しピン 1 1と第 2型本体 5との間 2 7 a 、 第 2型本体 5とホルダ 7との間 2 7 b、 及び冷却管 1 5と橥 2型本体 5との間 2 7 cには、 それそれ少なくとも気体が流通可能な隙間が確保されており、 本実 施の形態では、 これらの隙間が後述する気体抜き通路 2 7として機能するように なっている。 , Holder 7, cooling means 9, and push pin 11. A cavity 13 corresponding to the product shape is formed between the first mold body 3 and the second mold body 5. The cooling means 9 includes a cooling pipe 15, a base 17 disposed at the base thereof, It has. The cooling pipe 15 has a double pipe structure, that is, it has a supply path 19 arranged at the axial center thereof and for sending the coolant toward the vicinity of the cavity 13, and is provided around the supply path 19. An annular return path 21 is provided coaxially with which the coolant returns to the base 17. The cooling pipe 15 penetrates through the second mold main body 5 and the holder 7 disposed outside the main body. The base part 17 is disposed outside the holder 7 and is provided with a coolant inlet 23 for sending coolant from a coolant supply source (not shown) to the supply path 19 and cooling from the return path 21. A coolant outlet 25 is provided for recovering the liquid to the coolant supply source. The coolant is sucked from the coolant outlet 25 and flows through the cooling pipe 15 while maintaining a negative pressure state. Further, the push pin 11 penetrates through the second mold body 5 and the holder 7 so as to be able to reciprocate in the longitudinal direction, one end of which is connected to a drive source (not shown), and the other end of which has a cavity 13. You can reach the position you want. Also, 27 a between the push pin 1 1 and the second mold body 5, 27 b between the second mold body 5 and the holder 7, and 27 between the cooling pipe 15 and the 2 mold body 5 In c, at least gaps through which gas can flow are secured, and in the present embodiment, these gaps function as a gas vent passage 27 described later.
次に、 以上のように構成されたダイカスト用金型の動作について説明する。 第 Next, the operation of the die casting die configured as described above will be described. No.
1型本体 3及び第 2型本体 5が合せられるとそれらの中に目的の鎵物製品を形作 るキヤビティ 1 3が形成される。 そして、 図示しないゲートを介してキヤビティWhen the first mold main body 3 and the second mold main body 5 are put together, a cavity 13 for forming a target animal product is formed in them. And via the gate not shown
1 3内に溶湯 2 9を注入する。 一方、 冷却管 1 5には冷却液を負圧状態で循環さ せておく。 このとき、 キヤビティ 1 3内に巣の発生原因になるような空気などの 気体が残存している場合に、 かかる気体は、 冷却液の負圧状態の循環に伴い気体 抜き通路 2 7を介して冷却管 1 5の戻り路 2 1内へと吸引 '排出される。 よってInject molten metal 29 into 13. On the other hand, the cooling liquid is circulated through the cooling pipe 15 under a negative pressure. At this time, if a gas such as air that causes nests remains in the cavity 13, the gas is discharged through the gas vent passage 27 along with the circulation of the negative pressure of the coolant. It is sucked and discharged into the return path 21 of the cooling pipe 15. Therefore
、 キヤビティ 1 3内の溶湯 2 9は、 巣の原因となるような気体が好適に除去され た状態で固まる。 このようにして铸物に巣が発生することが防止されている。 溶 湯が固まったら、 一対の型本体 3及び 5を相互に分離し、 キヤビティ 1 3から製 品としての鎢物を取り出す。 また、 このとき、 錶物が第 2型本体 5から好適に離 隔するように押しピン 1 1の端部を第 2型本体 5の合せ面 P Lから突出させる。 すなわち、 本実施の形態では、 押しピン 1 1は、 錶物の型本体からの離隔を促す 本来の機能に加えて、 気体抜き通路 2 7を構成する隙間の一部を形成する働きも ある。 The molten metal 29 in the cavity 13 solidifies in a state in which a gas that causes nests is suitably removed. In this way, nests are prevented from being formed on animals. When the molten metal is solidified, the pair of mold bodies 3 and 5 are separated from each other, and the product as a product is taken out of the cavity 13. At this time, the end of the push pin 11 protrudes from the mating surface PL of the second mold main body 5 so that the object is appropriately separated from the second mold main body 5. That is, in the present embodiment, the push pin 11 promotes separation of the animal from the mold body. In addition to the original function, it also has a function of forming a part of the gap forming the gas vent passage 27.
さらに、 本来、 型に冷却管を揷入する場合、 両者の間に冷却液のシール手段を 介在させる必要があるが、 本実施の形態では、 気体抜き通路として、 第 2型本体 5と冷却管 1 5との間の隙間を積極的に利用する態様であるため、 上記のような シール手段を省略することができる。 また、 冷却液を冷却管に圧送する態様で冷 却液の循環を行う場合には、 シール手段を設けなければ、 第 2型本体 5と冷却管 1 5との間から冷却液の漏洩が生じる恐れがあるが、 本実施の形態では、 冷却液 を冷却管から吸い出す態様であるため、 上記のようにシール手段を省略しても、 冷却液の漏洩が生じることを回避することができる。  Furthermore, when a cooling pipe is originally inserted into the mold, it is necessary to interpose a cooling liquid sealing means between the two. However, in the present embodiment, the second mold body 5 and the cooling pipe are used as gas vent passages. Since this is a mode in which the gap between the first and the second is positively used, the sealing means as described above can be omitted. When the cooling liquid is circulated by pumping the cooling liquid to the cooling pipe, leakage of the cooling liquid occurs between the second mold body 5 and the cooling pipe 15 unless a sealing means is provided. Although there is a danger, in the present embodiment, since the cooling liquid is sucked out from the cooling pipe, even if the sealing means is omitted as described above, it is possible to avoid the leakage of the cooling liquid.
さらに、 万が一、 第 2型本体 5における冷却管 1 5の端部近傍に亀裂 3 1が発 生した場合でも、 本実施の形態では、 冷却液が負圧状態で循環しているため、 冷 却管 1 5内の冷却液がこの亀裂 3 1からキヤビティ 1 3に流出することはなく、 逆にキヤビティ 1 3内の気体が亀裂 3 1から冷却管 1 5内へ排出される。 すなわ ち、 亀裂 3 1を、 巣の発生防止のための気体抜き手段として利用することも可能 となっている。  Furthermore, even if a crack 31 occurs near the end of the cooling pipe 15 in the second mold body 5, the cooling liquid is circulated in the negative pressure state in the present embodiment, so that the cooling is performed. The coolant in the pipe 15 does not flow out of the crack 31 into the cavity 13, and the gas in the cavity 13 is discharged from the crack 31 into the cooling pipe 15. In other words, the crack 31 can be used as a venting means to prevent nests.
なお、 本発明のダイカスト用金型は、 押しピンを設け、 気体抜き手段として、 押しピンと第 2型本体との間、 第 2型本体とホルダとの間、 及び冷却管と第 2型 本体との間に生じる各隙間から構成される気体抜き通路を用いることに限定され るものではない。 よって、 例えば、 キヤビティと冷却管とを直接連通する専用の 気体抜き通路を、 気体抜き手段として用いてもよい。  The die-casting mold of the present invention is provided with a push pin, and as a gas releasing means, between the push pin and the second mold body, between the second mold body and the holder, and between the cooling pipe and the second mold body. However, the invention is not limited to the use of the gas vent passage formed by the gaps generated between the two. Therefore, for example, a dedicated gas vent passage directly connecting the cavity and the cooling pipe may be used as the gas venting means.
以上説明したように、 本発明のダイカスト用金型によれば、 キヤビティ内の気 体を冷却手段へ排出することにより、 錶物に巣が発生することを防止することが できる。  As described above, according to the die-casting die of the present invention, it is possible to prevent nests from being formed in the waste by discharging the gas in the cavity to the cooling means.
また、 気体抜き通路を、 押しピンと型本体との間の隙間、 型本体とホルダとの 間の隙間、 及び冷却管と型本体との間の隙間より構成する場合、 押しピンを、 錶 物の離隔を促すためだけでなく、 錡物に巣が発生することを防止するためにも利 用することができる。  When the gas vent passage is composed of a gap between the push pin and the mold body, a gap between the mold body and the holder, and a gap between the cooling pipe and the mold body, the push pin is formed by It can be used not only to promote separation, but also to prevent nests from forming on animals.
