Problems solved by technology

[0003] At present, for the die-casting machines on the market, the main reasons for the safety accidents of the mold clamping mechanism are as follows: 1. Some users modify the safety door shut-off switch for convenience, and short-circuit the safety door shut-off switch directly, so as to ensure personal safety The safe safety door shut-off switch is in the normally closed "ON" state for a long time, so that the condition that limits the mold closing action is in a long-term satisfied mold closing state regardless of whether the safety door is closed
2. For the convenience of operation, some users arbitrarily connected the two-handed mold closing button on the operation panel directly and changed it to one-handed operation, which caused potential safety hazards during operation.
3. Faults such as valve jamming or leakage of the mold closing valve cause mold closing under conditions that do not meet the mold closing conditions, which can easily cause injury and pose a great safety hazard

Embodiment 1

[0032] See figure 1 , Die-casting machine mold clamping safety control method, among which, it should be noted that when the die-casting machine is in the state of mold loading and manual, the machine mold clamping must meet the following five conditions at the same time: 1) mold opening stop, 2) top return stop; 3 ) Pressing back stop, 4) Pulling out the core, 5) Both hands press the 2 buttons to close the mold to close the mold; In the semi-automatic state of the die-casting machine, the machine must meet the following six conditions at the same time: 1) Open the mold, 2 ) Top return stop; 3) Press return stop, 4) Pull out the core stop, 5) Press the 2 mold clamping buttons with both hands, 6) Close the front and rear safety doors at the same time and send a signal to close the mold.

[0033] The die-casting machine mold clamping safety control method includes the following steps:

[0034] a. The central control center performs in-position detection of the die-casting machine's ...

Embodiment 2

[0040] A storage device that stores multiple execution instructions, the execution instructions being used by the central control center to load and execute the following operations:

[0041] a. The central control center performs in-position detection of the die-casting machine's limit switch, proximity switch or electronic ruler for mold opening stop, top return stop, core pull stop and press return stop. If any switch or electronic ruler is not in place, then Send an alarm signal to the alarm device and prohibit the die-casting machine from closing the mold. The alarm device will give an alarm after receiving the signal. Among them, the in-position detection of mold opening stop, top return stop, core pull stop and press return stop refers to the in-position detection of die casting machine When in the original position, check whether the position of the action is in the preset position;

[0042] b. The safety door inspection module checks the closing of the front and rear safet...

Embodiment 3

[0047] A die-casting machine mold clamping safety control system includes a central control center, an alarm device, a safety door detection module, a mold clamping button detection module, an electronic ruler detection module, and a storage device for storing multiple execution instructions. The execution instructions are used for The control center loads and performs the following operations:

[0048] a. The central control center performs in-position detection of the die-casting machine's limit switch, proximity switch or electronic ruler for mold opening stop, top return stop, core pull stop and press return stop. If any switch or electronic ruler is not in place, then Send an alarm signal to the alarm device and prohibit the die-casting machine from closing the mold. The alarm device will give an alarm after receiving the signal. Among them, the in-position detection of mold opening stop, top return stop, core pull stop and press return stop refers to the in-position detectio...

Abstract

The invention provides a die-closing safety control method for a die-casting machine, a storage device, and a die-closing safety control system. A central control center controls an alarm device to alarm and stop die-closing action when a safety door detection module, a die-closing button detection module and an electronic ruler detection module have feedbacks according to the detection of the safety door detection module, the die-closing button detection module and the electronic ruler detection module, so that the die-casting machine is in a safety alarm state in any state; and once in the case of misoperation or a hydraulic fault, the alarm device is triggered to alarm, so that the absolute safety of operating personnel is guaranteed, and the safety performance of the die-casting machine is improved.

Description

Technical field [0001] The invention relates to the technical field of die-casting machines, and mainly relates to a die-casting machine mold clamping safety control method, a storage device and a mold clamping safety control system. Background technique [0002] Die casting machine is a machine used for pressure casting, which hydraulically injects molten metal into a mold under pressure to cool and form it. After the mold is opened, solid metal castings can be obtained. The existing die-casting machine is mainly composed of mold clamping mechanism, injection mechanism, hydraulic system and electric control system. [0003] At present, for die-casting machines on the market, the main reasons for the safety accidents of the clamping mechanism are as follows: 1. In order to facilitate unauthorized modification of the safety door closing switch, some users will short-circuit the safety door closing switch directly to ensure personal safety. The safe safety door closing switch has be...
