Background

At present, a mold with an elastic ejecting block is a common forming mold. The ejection block is manufactured in a matched mode according to the shape of a specific part on a molded product made of the material sheet and is used for realizing die assembly molding of the specific part in the die assembly process. In order to prevent a straight material sheet from shaking in the die assembly process, the part of the material sheet corresponding to the ejection block is placed to be in a state of being attached to the ejection block as much as possible, so that the ejection block can press the material sheet when the material sheet is stamped by die assembly, and the material sheet is stabilized.

However, the above method of stabilizing a web using a flip-top block is only suitable for forming a web resembling a "straight" web, and is not suitable for an inverted "V" web. This is because when a portion of the web is attached to a flat surface of the mold, another portion of the web is inevitably not fitted to the shape of the mold due to the presence of the bent portion, and the web is left in a floating state. At this time, because the elastic top block is also in an inverted V shape, when one side of the material sheet is in a horizontal state, the other side of the material sheet is relatively protruded due to the existence of the bent part. The convex part of tablet can contact with the superficial part of tablet earlier at the in-process of punching press tablet to lead to the tablet to rock, can't carry out effectively steadily and produce.
