It is fixed on the lower side of the molding block positioning worktable, which facilitates working triggering and can also avoid false triggering and false operation. The triggering distance of the proximity switch is 0-2mm.

[0020] The effect of adopting the above technical solution is that workers can operate by hand with tweezers and directly trigger the proximity switch. The proximity switch is only sensitive to metal parts and cannot be triggered by non-metallic objects, which avoids the possibility of malfunction during operation and makes the operation more convenient and safer.
