Problems solved by technology

[0007] If a period of time elapses after the injection molding machine stops, the lubricant supplied between the bush and the connecting pin may accumulate downward due to the influence of gravity, resulting in a deviation in the distribution of the lubricant on the sliding surface.
If the injection molding machine is operated in such a state that the distribution of the lubricant is poor, the bushing may be worn out at the part where the lubricant is exhausted.

no. 1 Embodiment approach ＞

[0025] (Injection molding machine)

[0026] figure 1 It is a figure which shows the state at the time of completion|finish of mold opening of the injection molding machine of 1st Embodiment. figure 2 It is a figure which shows the state at the time of mold clamping of the injection molding machine of 1st Embodiment. Figure 1 to Figure 2 Among them, the X direction, the Y direction, and the Z direction are mutually perpendicular directions. The X direction and the Y direction indicate the horizontal direction, and the Z direction indicates the vertical direction. When the mold clamping device 100 is a horizontal type, the X direction is the mold opening and closing direction, and the Y direction is the width direction of the injection molding machine 10 . like figure 1 and figure 2 As shown, the injection molding machine 10 includes a mold clamping device 100 , an ejector device 200 , an injection device 300 , a moving device 400 , a control device 700 , and a frame 900...

no. 2 Embodiment approach ＞

[0154] Next, the injection molding machine 10 according to the second embodiment will be described. The injection molding machine 10 according to the second embodiment differs from the injection molding machine 10 according to the first embodiment in the operation when the injection molding machine 10 is stopped and the operation when the injection molding machine 10 starts operating (restarting the operation). The other structures are the same, so repeated description is omitted.

[0155] Figure 8 It is a figure which shows the structural element of the control apparatus 700 with which the injection molding machine 10 which concerns on 2nd Embodiment is equipped with functional blocks. The control device 700 of the injection molding machine 10 according to the second embodiment (refer to Figure 8 ) and the control device 700 of the injection molding machine 10 according to the first embodiment (refer to Image 6 ) is different in that a lubricant suction step control uni...

Abstract

The invention provides an injection molding machine capable of suppressing wear on a sliding surface of a link mechanism. An injection molding machine is provided with: a movable platen (120); a rear pressure plate (130); a link mechanism (150); a lubricant supply device (500) that supplies lubricant to at least one of a connection part (40) that connects the movable pressure plate and the links, a connection part that connects the links to each other, and a connection part that connects the rear pressure plate and the links; and a control unit (700) for controlling the lubricant supply device (500), in which at least one of the coupling parts (40) has: a bush (55); a connecting pin (50); supply paths (62, 63); and discharge paths (67, 68), the lubricant supply device (500) has a supply mechanism (502) and a discharge mechanism (70), and the control unit (700) executes a lubricant supply step in which the supply mechanism (502) is operated to supply lubricant to the bearing clearance (65) before a molding cycle step in which injection molding is performed when the stop time is longer than a threshold time.

Description

[0001] This application is a divisional application with an application date of March 27, 2019, an application number of 201910236147.3, and an invention-creation titled "Injection Molding Machine". technical field [0002] This application claims priority based on Japanese Patent Application No. 2018-068782 filed on March 30, 2018. The entire contents of the Japanese application are incorporated herein by reference. [0003] The present invention relates to an injection molding machine. Background technique [0004] There is known an injection molding machine that performs mold opening and closing and mold clamping of a mold using a toggle link mechanism. The toggle link mechanism is connected to the connecting rod by a connecting pin, and a bushing is provided between the connecting rod and the connecting pin. If the mold is repeatedly opened and closed, the bushing and the connecting pin slide, causing the bushing to wear. [0005] Therefore, there is known a method of ...
