Beschreibung
Zusammenfassung:	The utility model relates to a hot runner mold technical field, in particular to an inner hot tip grating structure of a hot runner mold. The inner hot tip grating structure is a hollow path and has a complete molding protruding part at the outlet. Between the protruding part and the side walls of the hot sprue outlet are formed runner holes. The runner holes are arranged at both sides of the protruding part. The end of the protruding part is a sharp end. The utility model is provided with a protruding part at the outlet of the inner hot tip grating and the protruding part is provided with runner holes at both sides. While the utility model is used, the raw materials flow out of the runner holes on both sides and meet at the sharp end of the protruding part. The protruding part in the structure makes it very easy to break the rubber and avoids gluing, reducing the waste of raw materials and improving the smoothness of plastic injection operation.
