What exactly does the KO hole in the injection mold mean? Where is the general position?
What I understand is that the KO hole is the top hole (the ejector rod of the injection machine is to be pushed into the thimble plate inside the mold,Male die fixing plate relative to the blue sky hole) public template location and number of die to see, if there is only one KO hole, is in the center of the normal template, but also the relative deviation of eccentric die. The larger the die, the more KO holes it has to design, but the position of the KO hole of the mold must be opened according to the top position of the KO machine. Otherwise, the mold thimble can not be pushed out!
Sometimes according to the actual situation of mold to open several KO hole, then to determine the other KO hole position according to the injection molding machine of the dynamic template parameters for dynamic injection molding machine has opened many holes as the top stick.
The KO hole, also called the top roller hole, is made on the rear die panel of the mould. The top rod can be directly pushed to the thimble plate when the injection top is out, and the hole dug on the panel is used for avoiding the empty. KO with the sprue hole position is on the same axis.
