AI Technical Summary

Problems solved by technology

However, due to the considerable mass of the movable platen and the driving force transmission mechanism, sudden acceleration or deceleration causes vibration and noise in the mold clamping device
Vibration generally reduces the durability of the device
In addition, the residual vibration generated at the time of stop (when the movable mold is in contact with the fixed mold) also leads to a decrease in the durability of the mold or a decrease in molding quality

Embodiment Construction

[0033] Hereinafter, each embodiment will be described in detail with reference to the drawings. In each figure, the same or corresponding symbols are attached to the same or corresponding structures, and explanations thereof are omitted. In addition, the moving direction of the movable platen when the mold is closed is set to the front, and the moving direction of the movable platen when the mold is opened is set to the rear.

[0034] figure 1 It is a figure which shows the state at the completion of mold closing of the injection molding machine 10 which concerns on one embodiment. figure 2 It is a figure which shows the state when the mold opening of the injection molding machine 10 of one embodiment is completed.

[0035] In the drawings, 10 is an injection molding machine, Fr is a frame of the injection molding machine 10, Gd is a guide composed of two guide rails laid on the frame Fr, and 11 is a fixed platen. The fixed platen 11 may be provided on a position adjustmen...

Abstract

An injection molding machine includes a drive source; a drive unit configured to be driven by the drive source; a driven unit configured to be driven by the drive source via the drive unit; a correction command generation unit configured to generate a correction command by correcting a command value received as input; and a feedback control unit configured to feed a control input to the drive unit based on the correction command and a feedback value from the drive unit or the driven unit.

Description

technical field [0001] The invention relates to an injection molding machine. Background technique [0002] Conventionally, a control method of a toggle lever type mold clamping device is known in which a toggle lever mechanism is arranged between a pressure receiving plate and the clamping plate, and the movement of the toggle lever mechanism is controlled by a drive unit provided on the pressure receiving plate. The crosshead moves forward and backward to perform mold opening and closing and mold clamping, wherein the negative acceleration until the clamping plate moves at a low speed and then decelerates or stops is controlled to be smaller than the negative acceleration until it decelerates or stops after moving at a high speed (for example, refer to the patent Literature 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2004-155063 [0004] However, in an injection molding machine, a mold clamping device opposes a fixed platen supporting a fixed mold and a...
