AI Technical Summary
In existing hot runner systems, the expansion difference and flatness error between the manifold and the upper template cannot be effectively compensated, leading to internal stress concentration and device damage.
The structure employs a support pad, which includes a first pad, a second pad, and an elastic element. Under the action of the elastic element, the height of the support pad can be adaptively adjusted to compensate for the expansion difference and flatness error between the diverter plate and the upper template.
It effectively prevents deformation of the internal flow channels of the manifold and local warping of the upper template, avoids glue leakage and device damage, and extends service life.
