Embodiment Construction

[0020] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each of the drawings, the same or corresponding components are given the same or corresponding symbols and descriptions thereof are omitted.

[0021] figure 1 It is a figure which shows the state at the end of mold opening of the injection molding machine of one embodiment. figure 2 It is a figure which shows the state at the time of mold clamping of the injection molding machine of one embodiment. The injection molding machine has a frame Fr, a mold clamping device 10, an operating device 70, a display device 80, a controller 90, and the like.

[0022] The controller 90 has a CPU (Central Processing Unit) 91 and a storage medium 92 such as a memory. The controller 90 controls the mold clamping device 10 , the operating device 70 , the display device 80 , and the like by causing the CPU 91 to execute a program stored in the storage medium 92 .

Abstract

The invention provides an injection molding machine which can regulate balance of axial force auxiliarily. The injection molding machine is provided with a plurality of connection rods, which are correspondingly stretched with mold clamping force, and a controller which controls the axial force on the conenction rods, and calculates preset value of operation quantity that changes the axial force according to the preset value of balance of the axial force.

Description

technical field [0001] This application claims priority based on Japanese Patent Application No. 2015-067680 filed in Japan on March 27, 2015. The entire contents of this Japanese application are incorporated herein by reference. [0002] The invention relates to an injection molding machine. Background technique [0003] The injection molding machine has a mold clamping device that performs mold closing, mold clamping, and mold opening of the mold device. The mold clamping device has a plurality of connecting rods extending in accordance with the mold clamping force (for example, refer to Patent Document 1). The mold clamping force is distributedly applied to a plurality of connecting rods so that the connecting rods are extended. The force that overcomes the extension of the connecting rod is called axial force. When there is a difference in the effective lengths of the plurality of connecting rods, a difference in axial force occurs between the connecting rod having a...
