As shown in FIG. 1, the injection molding machine includes a frame Fr, a mold clamping device 10, an injection device 50, and a controller 70.

The mold clamping device 10 performs mold closing, mold clamping, and mold opening of the mold apparatus 30. The mold clamping device 10 includes, for example, a fixed platen 12, a movable platen 13, a rear platen 15, a tie bar 16, a toggle mechanism 20, and a mold clamping motor ( 26). In the description of the mold clamping device 10, the moving direction of the movable platen 13 at the time of mold closing (the right direction in Fig. 1) is made forward, and the moving direction of the movable platen 13 at the time of mold opening (Fig. 1 will be described later with the left direction.

The stationary platen 12 is fixed to the frame Fr. The stationary mold 32 is attached to the surface opposite to the movable platen 13 in the stationary platen 12.

The movable platen 13 is movable along the guide (for example, guide rail) 17 attached to the frame Fr, and can move forward and backward with respect to the stationary platen 12. The movable mold 33 is mounted on the surface opposite to the stationary platen 12 in the movable platen 13. The mold apparatus 30 includes a fixed mold 32 and a movable mold 33.

By moving the movable platen 13 relative to the stationary platen 12, mold closing, mold fastening, and mold opening of the mold apparatus 30 are performed.

The rear platen 15 is connected to the fixed platen 12 via a plurality of tie bars 16 (for example, four), and is mounted on the frame Fr so as to be movable in the mold opening and closing direction. . In addition, the rear platen 15 may be movable along the guide provided on the frame Fr. The guide of the rear platen 15 may be common to the guide 17 of the movable platen 13.

In the present embodiment, however, the fixed platen 12 is fixed to the frame Fr, and the rear platen 15 is movable in the mold opening and closing direction with respect to the frame Fr. ) May be fixed to the frame Fr, and the fixing platen 12 may be movable in the mold opening and closing direction with respect to the frame Fr.

The tie bar 16 is parallel to the mold opening and closing direction and extends in accordance with the mold clamping force. At least one tie bar 16 is provided with a clamping force detector 18. The clamping force detector 18 may be a strain gauge type, and detects the clamping force by detecting the deformation of the tie bar.

However, the clamping force detector 18 is not limited to the strain gage type, but may be piezoelectric, capacitive, hydraulic, electronic, or the like, and the mounting position thereof is not limited to the tie bar 16.

The toggle mechanism 20 is disposed between the movable platen 13 and the rear platen 15 and is mounted to the movable platen 13 and the rear platen 15, respectively. As the toggle mechanism 20 expands and contracts in the mold opening and closing direction, the movable platen 13 moves forward and backward with respect to the rear platen 15.

The mold clamping motor 26 moves the movable platen 13 through the toggle mechanism 20. Between the clamping motor 26 and the toggle mechanism 20, a ball screw mechanism as a motion converting portion 27 which converts the rotational movement of the clamping motor 26 into a linear motion and transmits it to the toggle mechanism 20 is provided. To be prepared.

When the mold clamping motor 26 advances the movable platen 13, mold closing is performed. After mold closing is completed, mold clamping force obtained by multiplying the thrust ratio by the clamping motor 26 is generated, and mold clamping is performed by the clamping force. At the time of mold clamping, the cavity space 34 is formed between the movable mold 33 and the stationary mold 32, and the cavity space 34 is filled with a liquid molding material. The molding material in the cavity space 34 is solidified to form a molded article. Thereafter, the mold clamping motor 26 retracts the movable platen 13 to perform mold opening.

The injection apparatus 50 fills the molding material in the mold apparatus 30. The injection device 50 has a cylinder 51, a screw 52, a metering motor 53, and an injection motor 54. In the description of the injection apparatus 50, unlike the description of the mold clamping apparatus 10, the moving direction of the screw 52 at the time of filling (the left direction in FIG. 1) is made forward, and the screw 52 at the time of weighing It demonstrates with the movement direction (right direction in FIG. 1) rearward.

The cylinder 51 heats the molding material supplied from the supply port 51a. The supply port 51a is formed in the rear part of the cylinder 51. A heating source such as a heater is provided on the outer circumference of the cylinder 51. The nozzle 56 is provided in front of the cylinder 51.

The screw 52 is disposed in the cylinder 51 so as to be rotatable and retractable.

The metering motor 53 sends the molding material forward along the spiral groove of the screw 52 by rotating the screw 52. The molding material is gradually melted by the heat from the cylinder 51 while being sent forward. As the liquid molding material is sent to the front of the screw 52 and accumulated in all of the cylinders 51, the screw 52 is retracted.

The injection motor 54 advances the screw 52 to fill the cavity space 34 of the mold apparatus 30 with the liquid molding material accumulated in front of the screw 52. Thereafter, the injection motor 54 presses the screw 52 forward to apply pressure to the molding material in the cavity space 34. The shortage of molding material due to short shot or shrink marks can be compensated for.

In addition, although the injection apparatus of this embodiment is an in-line screw system, it may be a preplasting system. The injection apparatus of the pre-plasting method supplies the molding material melted in the plasticizing cylinder to the injection cylinder, and injects the molding material into the mold apparatus from the injection cylinder. The screw is disposed rotatably or rotatably and retractably in the plasticizing cylinder, and the plunger is retractably disposed in the injection cylinder.

The controller 70 controls the mold clamping device 10 and the injection device 50. The controller 70 has an operation unit 71, a display unit 72, and a control unit 75. The operation unit 71 and the display unit 72 are integrally provided, and the touch panel 73 is configured by the operation unit 71 and the display unit 72.

The operation unit 71 receives an input operation of the operator, and outputs an operation signal corresponding to the input operation of the operator to the control unit 75.

The display unit 72 displays an operation screen according to the input operation of the operation unit 71 under the control of the control unit 75. The operator sets the mold clamping device 10, the injection device 50, and the like by operating the operation unit 71 while looking at the operation screen 80 displayed on the display unit 72.

2 is a diagram illustrating an operation screen according to an embodiment of the present invention. The operation screen 80 has operation switch buttons 81A to 81D and operation permission button 83 on the same screen. In response to the plurality of types of operations A to D of the injection molding machine, a plurality of operation switch buttons 81A to 81D are provided. The operation switch buttons 81A to 81D and the operation permission button 83 correspond to the input unit described in the claims. Since the execution process of the operation A-D by the control part 75 is the same, the execution process of operation A is demonstrated typically. In addition, the operation permission button 83 is an input part which is necessary for execution of any of several types of operations A-D.

The control unit 75 outputs an execution signal for executing the operation A when both the operation switch button 81A and the operation permission button 83 displayed simultaneously on the operation screen 80 are operated, and both are operated. Do not output the execution signal until The execution signal is sent to apparatuses such as the mold clamping apparatus 10 or the injection apparatus 50, the apparatus operates in accordance with the execution signal, and operation A is executed. Since a plurality of operations are required for the execution of the operation A, malfunctions can be suppressed.

An input unit such as the operation switch button 81A or the operation permission button 83 may display the presence or absence of operation of the input unit. The control unit 75 may switch designs such as coloration and shape of the input unit depending on whether or not the input unit is operated. It can visually recognize how the control unit 75 recognizes the presence or absence of the operation of the input unit.

The control unit 75 outputs an execution signal when the operation switch button 81A and the operation permission button 83 are operated according to a predetermined rule, and does not output the execution signal when an operation that does not comply with the rule is performed. You don't have to. Since a rule is provided for a plurality of operations required for the execution of the operation A, malfunctions can be further suppressed. As a rule for outputting the execution signal, the one registered in the storage unit 76 is used.

The rule for outputting the execution signal includes, for example, an operation procedure and the like. As an operation procedure, for example, (1) operation of the other (for example, operation switch button 81A) is performed after operation of one (for example, operation permission button 83), (2) both The operation being performed simultaneously, (3) one operation (for example, operation permission button 83) is performed first, and the operation of the other (for example, operation switch button 81A) is performed during one operation. Etc. can be mentioned. In the case of (2) or (3), since simultaneous touch of a plurality of points on the operation screen 80 is required, the reliability is high. Since said (3) has more restrictions than said (2), reliability is higher than said (2). In the case of (2) or (3) above, a multi-touch panel capable of simultaneously detecting a plurality of touch points is used. On the other hand, in the case of (1), in addition to the multi-touch panel, a single touch panel for detecting one touch can be used.

The rule for outputting the execution signal may include an operation time, for example, one operation may be performed longer than the other operation. The rule for outputting the execution signal may include both an operation sequence and an operation time, and for example, the other operation may be performed within a predetermined time from the start of one operation. The rules for outputting an execution signal may vary.

The rule for outputting the execution signal may be level-divided into a plurality of steps. For example, the rule for outputting the execution signal may be level-divided according to the magnitude of risk due to misoperation. The higher the risk of misoperation, the more reliable the rule may be used.

The control unit 75 may select a rule for outputting an execution signal from a plurality of kinds of rules registered in advance. This selection may be performed according to a predetermined input operation or may be performed for each type of execution signal. The operator can select a rule for outputting the execution signal by inputting the magnitude of the risk due to an incorrect operation for each type of the execution signal.

In addition, in this embodiment, although operation of two input parts is required for execution of one operation | movement A, you may require operation of three or more input parts.

In addition, in this embodiment, although one rule is set for the operation of a plurality of input units, a plurality of rules may be set, different execution signals may be output for each rule, and different kinds of operations may be performed for each rule. The number of input parts can be reduced.
