Embodiment Construction

[0075] Embodiments of the present invention will be described below based on the drawings. In addition, in a cylinder, "stretching" means advancing the piston rod to extend the entire length of the cylinder, and "retracting" means retracting the piston rod to shrink the entire length of the cylinder.

[0076] 【Example】

[0077] Such as figure 1 As shown, the injection molding apparatus 10 is a device whose main elements are a mold clamping apparatus 20 that clamps a mold 12 with a mold clamping axis vertical; and an injection apparatus 50 disposed vertically above the mold clamping apparatus 20 . . The die 12 is composed of, for example, a lower die 13 and an upper die 14 .

[0078] The mold clamping device 20 has a base 21, a pressure plate 22, a turntable 23, a powerful mold opening mechanism 24, a mold clamping mechanism 25, a traction plate 29, a split nut 26, a mold opening and closing mechanism 27, a movable plate 28, a connecting rod 31, and the control unit 32.

Abstract

Disclosed are a mold clamping device having a half nut and an injection molding apparatus.Even with the mold clamping device using the split nut, a mold ejector or the like can be placed on a movableplate, and a mold can be opened powerfully without increasing the axial force of a mold opening and closing mechanism.The split nut (26) is arranged below a traction sheave (29) arranged in the lowerposition. An upper mold ejector (60) is arranged on the upper movable plate (28).In addition to the mold opening and closing mechanism (27), a powerful mold opening mechanism (24) is also arranged. The powerful mold opening mechanism (24) has large axial force and small stroke.The powerful mold opening mechanism (24) implements the powerful mold opening in the early stage of the mold opening process. The mold opening and closing mechanism (27) has small axial force and large stroke. The remaining part of the mold opening process is implemented by the mold opening and closing mechanism (27). Provided is a mold clamping device capable of powerful mold opening without increasing the axial force of the mold opening and closing mechanism.

Description

technical field [0001] The present invention relates to a mold clamping device having a split nut, and an injection molding device including the mold clamping device. Background technique [0002] Injection molding equipment for injection molding resin molded products has become widespread. The injection molding device is composed of a mold clamping device for fastening the mold and an injection device for injecting a resin material into the mold. [0003] The mold consists of a fixed mold and a movable mold. The movable mold moves along the clamping axis relative to the stationary fixed mold, and the mold is opened and closed. [0004] Clamping devices with a horizontal clamping shaft and vertical clamping shafts are widely used. [0005] Various structures have been proposed about the mold clamping apparatus whose mold clamping axis is vertical (for example, refer patent document 1, patent document 2). [0006] Patent Document 1 discloses a mold clamping device in whic...
