Description

  The present invention relates to a frame of an injection molding machine.

  Conventionally, as shown in FIG. 6, the frame 1 of this type of injection molding machine generally has a lower frame 2 in which metal members are attached in a frame shape, an upper frame 3 having the same configuration as the lower frame 2, and the lower frame. A rectangular parallelepiped frame is formed by a plurality of support frames 4 that are vertically attached to 3 and support the upper frame, and a mold clamping device 5 and an injection device 6 are arranged in the front-rear direction, and an injection molding machine is mounted. ing. The space inside the frame 1 is provided with a molded product take-out space, various electrical control panels for driving the injection molding machine, a hydraulic mechanism for control, and the like.

  However, in the electric injection molding machine, there is no hydraulic mechanism or the like unlike the hydraulic injection molding machine, and a space portion 7 where nothing is used may be formed inside the frame 1.

On the other hand, separately installed peripheral devices such as a temperature controller require a relatively large space, and these peripheral devices are placed in the frame space portion 7 in order to narrow the work space. Such a peripheral device such as a temperature controller is relatively heavy, and it is very difficult to get over the width direction member 8 of the frame lower frame 3 and place it in the space portion 7 from the arrow E direction. , Also requires careful attention. Therefore, Japanese Patent No. 2711490 discloses a configuration in which at least one width direction member 8 in the front-rear direction of the frame lower frame 3 is removed, and peripheral devices and the like can be easily delivered to the frame space 7.
Japanese Patent No. 2711490

  However, in the frame described in the above-mentioned Japanese Patent No. 2711490, since at least one width direction member in the front-rear direction is not attached, a relatively small injection molding machine may be used. The frame has a drawback that it is weak in strength, and overcoming it has been an issue.

  It is an object of the present invention to provide an injection molding machine frame that overcomes the aforementioned drawbacks.

  In order to achieve the above object, the present invention provides a lower frame in which members are attached in a frame shape, an upper frame attached in the same manner as the lower frame, and a vertical frame attached to the lower frame. Select a member in the width direction of at least one of the front and rear ends of the rectangular parallelepiped in the frame on which the injection molding machine is mounted that is formed in the shape of a rectangular parallelepiped by a plurality of supporting support frames and the clamping device and injection device are arranged in the front-rear direction. The frame of the injection molding machine is characterized in that it can be removed and the frame state can be eliminated.

  The lower frame width direction member is preferably a frame of an injection molding machine having both ends attached with bolts or the like.

  The lower frame width direction member is more preferably a frame of an injection molding machine characterized in that one end can be used as a fulcrum and can be rotated in the horizontal direction or the vertical direction with respect to the lower frame.

  Further, the lower frame width direction member is more preferably a frame of an injection molding machine characterized in that it can be translated upward along the support frame.

  Further, the lower frame width direction member that is rotated or translated in the upward direction is a more suitable frame of the injection molding machine if a position holding device for maintaining the moving position is provided.

  According to the present invention, when a peripheral device or the like is not taken in or out of the space in the frame, the lower frame width direction member keeps the lower frame in a frame shape, and the problem of weakening in strength is overcome.

Next, an embodiment of the present invention will be described in the mold clamping device mounting portion of an injection molding machine.
This will be described with reference to FIGS. Reference numeral 10 denotes a frame for governing the injection economy, and a mold clamping device 11 indicated by a chain line is mounted. This frame 10 supports the upper frame 13 by a lower frame 12 in which members are assembled in a frame shape, an upper frame 13 in which members are also assembled in a frame shape, and a column frame 14 provided in a plurality perpendicular to the lower frame 12. A rectangular parallelepiped frame is formed, and a space 15 is formed in the frame 10.

Since it is configured in this way, when the temperature controller 16 which is a peripheral device, for example, cannot be put into the space 15 in the frame, the width direction member 17 is attached to the lower frame 12 by the bolt 18 and is kept in a frame shape. In the state shown in FIG. 2 (a), when the temperature controller 16 is inserted into the space 15 in the frame as indicated by the arrow C, the bolt 18 is removed, and the width direction member 17 is disposed on the lower frame 12. Therefore, the end face 19 teeth are opened, and the state shown in FIG. 2B is obtained, so that the temperature controller 16 can be easily put into the space 15.
Conversely, when the temperature controller 16 in the space 15 is pulled out, the temperature controller 16 can be pulled out after removing the width direction member 17 and opening the end face 19 as described above.

In the above-described embodiment, the example in which the width direction member is attached to the lower frame by the bolt is described. However, the present invention is not limited to this. If the injection molding machine is small and the width direction member is relatively light, for example, As shown in FIG. 3, the width direction member 20 is pivotally attached with one end A as a fulcrum, the bolt 21 at the other end B is removed, and then the other end B is rotated in a direction perpendicular to the lower frame as a chain line 20a. 19 may be opened, and in order to keep the moving position of the width direction member 20a, the bolt 21 at the other end B can be attached to the frame by the bolt 21.
Here, when the injection molding machine is large and the width direction member is heavy, it can be rotated in the horizontal direction with respect to the lower frame.

Further, as shown in FIGS. 4 and 5, the width direction member 30 can be translated upward along the groove 32 provided in the column frame 31, and the end face 33 can be opened as the width direction member 30a. good. In that case, the width direction member 30a may be prevented from falling by protruding into the groove 32 such as the pin 34 to prevent the falling.
In addition, as the position holding means of the lower frame width direction member, the position holding and fall prevention may be performed using a sphere, a spring, and a spherical stopper plate. Various other can be realized.

  Since it is configured as described above, it is possible to easily insert and remove peripheral devices such as a temperature adjusting device and a measuring device into and out of the space in the frame without reducing the strength of the frame. The strength problem of the body is also overcome.
