Detailed Description

The invention will be further described with reference to the following examples:

as shown in FIGS. 1-6, molding line joint box detection device, including the liftable support body, the support body top is equipped with proximity switch 11, and the support body top is connected with screw rod 7, and the support body top still rotates the arm 8 that cranks that is equipped with L shape, arm 8 that cranks rotate and set up on screw rod 7. In the initial state, the cross arm of the L-shaped crank arm 8 is in a horizontal state and is close to the proximity switch 11, the trailing arm of the L-shaped crank arm 8 is in a vertical state, and the bottom of the trailing arm is 2-5 mm higher than the upper plane of the sand box 15.

Wherein, the bottom end of the longitudinal arm is arc-shaped. One side of the bottom end of the trailing arm is provided with a limiting plate 14, and the limiting plate 14 is fixed on the frame body, so that the L-shaped crank arm can keep an initial state.
