Abstract
A double mold locking apparatus includes a mold unit and a plurality of positioning devices. The mold unit includes a fixed mold, a movable mold, a plurality of support rods and a plurality of driving cylinders. Each of the positioning devices includes a high pressure locking cylinder, two opposite semi-nuts and a position finder. Thus, the position of each of the support rods relative to the semi-nuts of the respective positioning device is micro-adjusted when the first die and the second die are opened and closed, so that a user only needs to calibrate the position of each of the support rods at the first time when the first die and the second die are opened and closed without having to adjust and calibrate the position of each of the support rods at each cycle.
