Angled-Mold Core Actuating Mechanism

摘要

The present invention provides an angled-mold core actuator (180, 280, 380). When actuated, an angled-cavity forming core (158) is extended into a mold cavity defined by a mold insert (154). The angled-cavity forming core (158) is disposed at a 3-dimensional angle into the mold insert (154) to form a cavity (104) in a molded product. The angled-cavity forming core is actuated by a driven pin (186, 286, 386) of the angled-mold core actuator (180, 280, 380).

主权项

1. A 3-dimensional angled cavity forming apparatus comprising:
an actuator body having two bores disposed axially at an angle to each other; a drive pin and a driven pin separately disposed in the two bores so that the drive and driven pins are slidably guided for reciprocation in the respective bore; wherein a portion of the drive or driven pin disposed inside the actuator body has a longitudinal flat formed parallel to the longitudinal axis of the relevant pin; a stopper pin disposed in the actuator body to cooperate with the longitudinal flat formed on the drive or driven pin; a free end of the driven pin is configured as a cavity forming core in association with a mold insert and defines a 3-dimensional cavity within the mold insert; and a channel of gradual changing direction for communicating between the two bores, with the channel being filled with an incompressible material so that when the drive pin is axially displaced, displacement of the drive pin is transmitted axially to the driven pin.
