Description

  The present invention relates to an injection molding machine, and more particularly, to an injection molding machine capable of changing a fixing position of a safety cover during machine transfer and machine operation.

  The injection molding machine is provided with a safety cover so that work can be performed safely when the machine is operated after the machine power supply is connected. FIG. 13 illustrates an injection molding machine (operation side during machine operation), and FIG. 14 illustrates an injection molding machine (counter operation side during machine operation). As shown in FIG. 13, the removable safety cover 1 is provided on the operation side surface (operation side 20) of the base frame 11, and the removable safety cover 4 is provided on the mold clamping device 12. Further, as shown in FIG. 14, a detachable safety cover 3 is provided on the non-operation side surface (non-operation side 21) of the base frame 11.

  Patent Document 1 has a safety cover that protects an operator from a mechanism portion arranged on a base frame, the safety cover has an upper bent portion, and the safety cover is once removed from the injection molding machine. Thereafter, a technique of an injection molding machine in which the upper bent portion is hooked on the upper surface of the base frame and temporarily placed is disclosed.

Utility Model Registration No. 3178426

  For example, in the injection molding machine as shown in FIGS. 13 and 14, the safety cover of the injection molding machine 10 is installed so that the operator's work can be performed safely when the machine is operated after the power supply of the machine is connected. However, if the safety cover 1 is fixed when the machine is moved, the storage space for the accessory (accessory) decreases, and workability deteriorates when the accessory is secured. If the safety cover 4 is fixed when the machine is moved, the crane may not be able to lift the machine.

In order to solve these problems, there is a method of removing the safety cover 1 and the safety cover 4 in advance when moving the machine and making it an accessory. However, in this case, since the number of accessories increases, There is a problem that the number of work steps increases.
Moreover, the technique disclosed in Patent Document 1 provides a structure of a safety cover for efficiently performing maintenance work and a temporary storage place for temporary storage, without increasing the number of accessories (accessories). It does not improve workability at the time of moving the machine or secure a space for storing accessories, and does not change the fixing position of the safety cover at the time of moving the machine and operating the machine.

  Accordingly, an object of the present invention is to provide an injection molding machine capable of changing the fixing position of the safety cover when the machine is moved and when the machine is operated, in view of the problems of the prior art.
