Document Type and Number:
Japanese Patent JP2627215
Kind Code:
B2
Abstract:
A toggle type mold clamping system is used for a vertical injection molding machine, including a toggle link mechanism. The toggle link mechanism has a pair of toggle rods (7A, 7B), a pair of toggle arms (9A, 9B) in the shape of a sideways V, and drive means (13A, 13B, 14, 15). Opposite ends of the toggle rods are pivotally coupled to an intermediate panel 2 and one end each of the toggle arms, respectively. At bends thereof, the toggle arms are pivotally coupled to a lower panel. The drive means is coupled to the lower ends of the toggle arms. The toggle arms are operated by the drive means to open and clamp molds. With this arrangement, the driving force can be effectively used to open and clamp the molds, thereby reducing the size of the drive means, and space in the lateral direction.
