Embodiment Construction

[0022] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0023] Such as figure 1 The error-proofing method for detecting extrusion pins in a die-casting mold includes the following steps:

[0024] (1) The die-casting machine enters the automatic mode;

[0025] (2) The die-casting machine is clamped in place;

[0026] (3) The die-casting machine performs the injection action;

[0027] (4) Cool for a certain period of time after injection;

[0028] (5) The extrusion pin is extruded according to the set time;

[0029] (6) The squeeze pin is retracted;

[0030] (7) The high temperature resistant photoelectric sensor switch detects the retraction action of the extrusion pin;

[0031] (8) If the high-temperature-resistant photoelectric sensor switches detect the retraction signal, the retraction signal is processed by PLC, and the cooling time is up to the die-casting machine to open the mold,...

Abstract

The invention discloses a detection mistake-proofing method and device for an extrusion pin in a die-casting die. A high-temperature-resistant photoelectric inductive switches are arranged at the positions corresponding to extrusion pin oil cylinders, and extrusion pin retreating motion is detected through the photoelectric inductive switches; if the photoelectric inductive switches detect retreating signals, the retreating signals are treated through a PLC, die sinking of the die-casting die is carried out once the cooling time is up, then a series of operation including piece taking and mist spraying are completed, and waiting for a next circulation is carried out; and if one of the photoelectric inductive switches does not detect the retreating signal, the retreating signal cannot be received by the PLC, and an alarm is given out for reminding operation technicists to conduct treatment. The device is stable, reliable and durable, the mistake-proofing performance is good, the device is convenient and practical, and the monitoring and control practicability of the die-casting production technological process is higher.

Description

technical field [0001] The invention belongs to the field of die-casting industrial manufacturing, and in particular relates to a method and device for detecting and preventing errors of extrusion pins in a die-casting mold. Background technique [0002] In the die-casting production process, taking out the parts by the robot needs to be carried out by ejecting the thimble, and the quantity and quality of the extruded pins inside the mold directly affect the production efficiency of the product. Broken needle is a frequent problem of extrusion pin inside the mold, which not only seriously affects the quality of the product and increases the scrap rate; but if it is not found in time, aluminum material will enter the broken part of the extrusion pin in the mold, affecting the progress of mold maintenance , Delay a lot of manpower time and reduce production efficiency. If we want to improve the production quality of die-casting production, we must improve the level of mold mo...
