Abstract
Description
複数のキャビティが形成されたキャビティ列を3列以上備え、前記キャビティを冷却する冷却媒体を流通させる冷却流路を備える射出成形用の金型であって、
前記冷却流路は、少なくとも1つ以上の供給口と、前記供給口と連通された分配管と、前記分配管と連通された供給管と、前記供給管と連通され前記キャビティの外周に設けられたキャビティ冷却部と、前記キャビティ冷却部と連通された排出管と、前記排出管と連通された集約管と、前記集約管と連通された少なくとも1つ以上の排出口と、により形成され、
前記供給管及び前記排出管は、前記キャビティ列に平行に、かつ前記キャビティ列毎にそれぞれ少なくとも1つずつ形成されている。
前記供給管及び前記排出管はそれぞれ前記キャビティ列毎に2つずつ形成され、
1つの前記供給管により前記キャビティ列の半分の前記キャビティ冷却部に前記冷却媒体が供給されると好ましい。
前記分配管及び前記集約管はそれぞれ前記供給口及び前記排出口毎に形成され、
各前記分配管及び各前記集約管はそれぞれ独立して形成されていると好ましい。
ネック型の列間の距離を変換するピッチ変換機構を備える成形機用の金型であって、
前記ピッチ変換機構との非干渉部に前記供給口及び前記排出口が形成されていると好ましい。
前記キャビティは、前記金型の凹部に嵌めこまれたインナーキャビティおよびキャビティリングの二つの部材から構成されるインナー部材により規定されていると好ましい。また、前記インナーキャビティは、前記キャビティを規定する内壁面と、射出成形時にネック型と当接する肩部と、を備え、前記キャビティリングは、前記キャビティリングが配置される空洞を内側に有する部材であり、前記肩部と当接する上面部を備え、前記インナーキャビティおよび前記キャビティリングの間に形成される流路が、前記キャビティ冷却部を構成するとさらに好ましい。
上記の構成により、一つの分配管32からの冷却媒体を外側のキャビティ列22a(22b)および内側のキャビティ列22cに好適に分配して供給することが可能となり、また、外側のキャビティ列22a(22b)および内側のキャビティ列22cの冷却媒体を集約させて一つの集約管36から排出することが可能になる。
例えば、分配管32や集約管36を、それぞれ外側の二つのキャビティ列22a、22bの間にわたって延在する単一(一本)の構成にし、そこに2つ以上の供給口31や排出口37を設けた構成にしても良い。また、前述の構成の場合、十分な冷却能力が満たされるようであれば、供給口31や排出口37はそれぞれ1つずつにしても構わない。
