FIG. 2 is a diagram for explaining a schematic configuration of the injection molding machine 100 according to the present embodiment.
As shown in FIG. 2, the injection molding machine 100 has a fixed die plate 2 on which a fixed mold 4 is attached on a base 1. On the same base 1, a movable die plate 3 to which a movable mold 5 is attached is movably mounted facing the fixed die plate 2.

A linear bearing guide 22 is laid on the base 1. A linear bearing 21 guided by the linear bearing guide 22 is attached to and supports the movable die plate 3.
The fixed die plate 2 is provided with a plurality of (four in this example) hydraulic clamping cylinders 50 having a short stroke and a large diameter, and a large-diameter piston 7b slides in the clamping cylinder 50. A tie bar 7 is directly connected to the piston 7b. The tie bar 7 is inserted into the insertion hole 3b of the movable die plate 3 when the opposing movable die plate 3 approaches due to mold closing. A plurality of ring-shaped grooves 7 a having an equal pitch are formed at the tip of the tie bar 7.

On the side surface opposite to the mold mounting surface of the movable die plate 3, a pair of half nuts 11 meshing with the ring-shaped groove 7a of the tie bar 7 are arranged so as to sandwich the axis of the insertion hole 3b from both sides. It is provided to operate with a hydraulic cylinder or the like in a direction perpendicular to the center. When the half nut 11 is in a closed state (for mold opening etc.), hydraulic pressure acts on the head side of the piston 7b of the tie bar 7, and when the tie bar 7 is pushed to the left in FIG. A support member 12 is provided to support the plate 3 so as not to be separated from the plate 3.
2 indicates the position of the movable die plate 3 when the mold is closed.

A cavity flow path serving as a flow path for the molten resin is formed in the fixed mold 4, and this cavity path is connected to the injection port of the injection cylinder 8 through the through hole of the fixed die plate 2.
The cylinder main body 8a of the injection cylinder 8 is provided with a plurality of ring-shaped heaters 9 spaced apart in the axial direction of the cylindrical cylinder main body 8a. The resin in the cylinder body 8a is melted by these ring heaters 9 and the screw 8b is rotated, so that the molten resin is passed between the fixed mold 4 and the movable mold 5 from the injection port at the tip of the cylinder body 8a. Injection into the cavity formed.

On the base 1, a ball screw shaft 13 is supported by a support base 17 and a support base 18 with its axial direction being freely restricted. A ball screw nut 14 is screwed onto the ball screw shaft 13. The ball screw nut 14 is attached to a bracket 3 a protruding from the side surface of the movable die plate 3. The ball screw shaft 13 is driven by the servo motor 15 via the power transmission mechanism 16, and the rotation speed and rotation speed are controlled by the controller 37.
When a pair of ball screw shafts 13 are provided symmetrically on the side surface of the movable die plate 3, a pair of rotations of the output shaft of one servo motor 15 is performed by a timing belt or a chain provided in the power transmission mechanism 16. By simultaneously transmitting to the ball screw shaft 13, the pair of ball screw shafts 13 are synchronously rotated.

The controller 37 controls the opening / closing operation of the mold composed of the fixed mold 4 and the movable mold 5.
From the state where the mold of FIG. 2 is opened, that is, the movable die plate 3 is sufficiently separated from the fixed die plate 2 as indicated by a solid line, the movable die plate 3 is movable with the fixed mold 4 as indicated by a two-dot chain line. The movable die plate 3 moves by the rotation of the ball screw shaft 13 driven by the servomotor 15 until the mold 5 is closed. The controller 37 slowly accelerates the movable die plate 3, moves it at a constant speed, then decelerates it and stops it just before the movable mold 5 contacts the fixed mold 4.
At the stop position of the movable die plate 3, the inner ring groove of the half nut 11 engages with the ring-shaped groove 7 a of the tie bar 7 and is coupled to the tie bar 7.

Next, hydraulic oil is fed into the mold clamping cylinder 50, and the mold is clamped.
Then, the molten resin is injected into the mold cavity from the injection cylinder 8 that passes through the fixed die plate 2 and is connected to the cavity flow path formed in the fixed mold 4.
The molten resin in the mold cavity is cooled and solidified to form a molded product. After cooling and solidification, pressure oil is sent to the head side of the piston 7b of the clamping cylinder 50, and the piston 7b is pushed out to release the mold. At this stage, the half nut 11 is reversely operated and the coupling with the tie bar 7 is released, and the ball screw shaft 13 rotates in the reverse direction when the mold is closed to move the movable mold 5 and the movable die plate 3 to the original position. To stop. After the molded product is taken out, the next mold closing starts.

  The hydraulic control circuit of the mold clamping cylinder 50 includes a hydraulic oil tank 39, a controller 37, a hydraulic pressure setting device 41 that sets a mold clamping hydraulic pressure calculated by proportional integral compensation, mold clamping start, mold release, tie bar positioning.

When the pressure oil is sent by exciting the solenoid a of the four-way switching valve 34, the other valve port of the four-way switching valve 34 communicates with the hydraulic pressure discharge direction. The hydraulic pressure on the right side is only a slight back pressure (1 kgf / cm ² ), and the hydraulic oil acts on the left side of the piston 7b to generate a clamping force on the piston 7b.
During the mold clamping process, injection of molten resin into the mold cavity and holding cooling are performed.

  If the solenoid a of the four-way switching valve 34 is energized to open the two-way switching valve 35 and operate in the direction in which hydraulic fluid is passed, the same hydraulic pressure acts on both sides of the piston 7b of the mold clamping cylinder 50. Due to the difference in operating area (the hydraulic operating area on the left side of the piston 7b is reduced by the area of the tie bar 7), the hydraulic operating force of the piston 7b is increased, and a releasing force is generated in the piston 7b.

As a result, the information management device 230 can increase the amount of information to be obtained, so that the failure determination by the failure determination unit 90 can be suitably performed. In addition, since the inspection worker can perform the inspection work while holding the inspection portable terminal 220, the inspection worker performs the inspection work according to the inspection program of the inspection portable terminal 220, so Therefore, the inspection can be performed appropriately and efficiently.

  In addition, the information management device 230 reads the information code attached to each part of the injection molding machine 100 by the code reading unit 74 of the inspection portable terminal 220 to acquire the part information, and based on the acquired part information, An estimate can be easily created.

In the above embodiment, the pump original pressure, injection pressure, mold clamping pressure, and injection heater temperature of the injection molding machine 100 are inspected. However, it is not necessary to check all of them, and of course, this is not necessary. It is possible to include other parameters.
Also, the configuration of the injection molding machine 100 can be any appropriate configuration other than those described above.
In addition to this, as long as it does not depart from the gist of the present invention, the configuration described in the above embodiment can be selected or changed to another configuration as appropriate.
