How can plastic die be afraid of thimble collision?
There are 3 ways I've seen: 1. Make a limit switch on the thimble board. 2. The ejector plate is forced back and the mechanism is forced to pull back. 3, in the mold base to do a first reset mechanism, the mold by the power of the mold, the ejector plate forced overwhelming!
If the thimble thimble plate. Then, you need to put on the machine and the ejector plate ejector rod screw close together, or adding the slingshot in mold between the thimble plate and the template, in order to ensure the line position of the sliding plate front thimble thimble reset.If it is an oblique needle position on it, in general, the supporting thimble line slider hole increased, at the same time need to grind some thimble head chamfer, also is a slider at the bottom of the marbles to do accurate positioning, because if the hole and also to a line between the sliding block the inclined surface and the upper surface to fall angle, so as not to shovel hit for a slider.
The die with a row position slider is a moving slider in the opening mode. The slider moves backward first, and then the ejector pin moves. In the closing of the die, the ejector pin returns the ejector pin to the front of the block when the slider is advancing. On the adjusted die, there should be no interference with the collision.
