Thereby, a material is placed on the lower die 120 and pressure is applied to the upper die 110, so that the degree of breakage or the degree of wear can be measured, and a not-shown penetration hole can be formed on the guide block 147 for penetration processing.
According to the present invention having the structure and effects as described above, the perforation can be penetrated while the composite shear durability test is performed due to the compact and efficient structure, and thus the efficiency of the process can be improved.
Fig. 5 is a control block diagram of a shear durability test mold apparatus for use in the evaluation of the service life of the mold wear resistance according to another embodiment of the present invention.
Referring to this drawing, various sensors and cameras as peripheral structures may also be provided in the shear durability test mold apparatus for mold wear resistance service life evaluation according to the present embodiment.

One or more false beepers 272 may also be suitable. Due to such an application of the error buzzer 272, the operator can immediately confirm the error (error) for the shear durability test process audibly and take action.
In addition, a power cut-off device 290 operated in conjunction with the controller 280 is further provided in the shear durability test mold device according to the present embodiment. The power cut-off device 290 is controlled by the controller 280 to cut off power to the device to stop the operation of the device.
That is, in the present embodiment, when controlling to supply the notification signal to the external notification unit 270, the controller 280 performs synchronous control to automatically cut off the power of the power cutoff device 290. Thus, the operation of the unnecessary device is cut off.
The controller 280 for performing this function may include a Central Processing Unit (CPU)281, a MEMORY (MEMORY)282, and SUPPORT circuitry (SUPPORT CIRCUIT) 283.
In the present embodiment, the central processing device 281 may be one of various computer processors industrially applicable in order to control the operation of the external notification portion 270 based on the measurement or detection signals of the upper die pressure measuring portion 251, the dual material loading necessity detecting portion 252, the piercing formation confirming portion 253, and the burr (burr) pattern detecting portion 254, and to drive the power cutoff device 290.
The MEMORY (MEMORY)282 is connected to the central processing unit 281. The memory 282 is a computer-readable recording medium, which may be provided locally or remotely, and may be, for example, at least one type of memory that is readily available, such as a Random Access Memory (RAM), a ROM, a floppy disk, a hard disk, or any form of digital storage.
SUPPORT CIRCUITs (SUPPORT CIRCUIT)283 are associated with central processing unit 281 to SUPPORT typical operation of the processor. Such support circuits 283 may include cache, power supplies, clock circuits, input/output circuitry, subsystems, and the like.
In the present embodiment, the controller 280 controls the operation of the external notification portion 270 based on the measurement or detection signals of the upper die pressure measuring portion 251, the two-material loading absence detecting portion 252, the perforation formation confirming portion 253, and the burr pattern detecting portion 254. At this time, a series of processes and the like in which the controller 280 controls the operation of the external notification portion 270 based on the measurement or detection signals of the upper die pressure measuring portion 251, the two-material loading absence detecting portion 252, the perforation formation confirming portion 253, and the burr (burr) pattern detecting portion 254 may be stored in the memory 282. Typically, software routines may be stored in the memory 282. Further, the software routines may be stored or executed by other central processing devices (not shown).
Although the processes according to the present invention have been described as being performed by software routines, at least some of the processes of the present invention can also be performed by hardware. Thus, the processes of the present invention may be implemented by software executing on a computer system, or may be implemented by hardware such as an integrated circuit, or may be implemented by a combination of software and hardware.
Even if this embodiment is applied, the composite shear durability test can be performed while the perforation can be penetrated due to the compact and efficient structure, and the process efficiency can be improved.
As described above, the present invention is not limited to the described embodiments, and it is apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention. Therefore, such modifications or variations are intended to fall within the scope of the claims of the present invention.
