ROTATION MOLD RELEASE MECHANISM AND INJECTION MOLDING MACHINE

WIPO Patent Application WO/2018/120455

A1

Disclosed are a rotation mold release mechanism including a rotation release unit and a plurality of dental core units which surround the rotation release unit, wherein the rotation release unit includes a rifle line (11) and a rifle line sleeve (12) that is sleeved on the rifle line (11),and matched internal and external threads are provided on the inside of the rifle line sleeve (12) and the outside of the rifle line (11) respectively, a main gear (14) is provided on the outer side of a bearing (13), the outer side of dental cores (15) is provided with a slave gear (18), and the dental cores (15) is linked with the rotation release unit via gear engagement, and an injection molding machine. Reciprocating movement of the rifle line (11) rotates the rifle line sleeve (12), the bearing (13) and the main gear (14), and then drives the dental core (15) to rotate to drive the product back by the dental core (15) under the association of the thread guiding structure of the dental sleeve ( 17) at the bottom of the dental core (15). Due to the function of the rotation stop gear of dental core insert (16), the product does not follow the rotation, thus achieving the purpose of rotation release of the core, and realizing simultaneous operation of product release and mold opening, which greatly improves production efficiency.
