AI Technical Summary

Technical Problem

During long-term work, the die-casting machine may cause the touch panel to lose control due to electrical or hydraulic system failure, and cause mis-closing, resulting in personal injury accidents or damage to the device.

Method used

A die-casting machine anti-clip device is designed, including installing a movable plate on the movable mold and installing a locking mechanism at the bottom of the movable plate. Through an infrared light curtain, whether there are other objects around the processing table are detected. When an object is detected, the locking mechanism operates, limits the lifting shaft, fixes the movable mold, and prevents mistaken clamping. At the same time, the acoustic and light alarm reminds the staff to check.

Benefits of technology

It effectively prevents the die-casting machine from being mis-clamped, ensures equipment safety and personnel safety, and avoids potential injuries and damage.

Abstract

The invention provides a mistaken clamping prevention device of a die casting machine, and belongs to the technical field of die casting machines, the mistaken clamping prevention device comprises a machining table, a fixed die is mounted at the top of the machining table, a movable die is mounted in the top area of the fixed die, and a movable plate is mounted at the top of the movable die; a locking mechanism is installed in the machining table and comprises two lifting shafts, two first gears, two second gears and an air cylinder, meshing fluted discs are installed at the bottoms of the second gears, and a positioning fluted disc is installed in an output shaft area of the air cylinder. A detection mechanism is installed around the machining table and comprises an infrared emitting light curtain arranged around the top table and an infrared receiving light curtain installed around the machining table. During die casting, if other objects are detected, the locking mechanism operates, the lifting shaft is limited through fluted disc clamping and gear meshing, then the movable die is fixed, the situation of mistaken clamping is prevented, and equipment safety and personnel installation are guaranteed.
