The molding die for a C-shaped half frame bracket of an automobile safety belt according to claim 1, wherein: under the action of the laser detection sensor and the lower thimble, the specification of the rivet filled in the workpiece to be riveted can be judged, and the error specification of the rivet is avoided: the rivet comprises a bottom hollow rivet and a bottom solid rivet, when the bottom hollow rivet is filled in a workpiece to be riveted on the float positioning plate, the top end of the upper section part of the lower thimble is inserted into the bottom hollow of the rivet, and the top height of the bottom hollow rivet detected by the laser detection sensor is S1; when the bottom solid rivet is filled in the workpiece to be riveted on the float positioning plate, the top end of the upper section part of the lower ejector pin is abutted against the bottom surface of the rivet, so that the rivet is lifted up by the lower ejector pin for a distance, and the top height S2 of the bottom solid rivet detected by the laser detection sensor is larger than S1, so that the rivet filled in the workpiece to be riveted is distinguished to be a bottom hollow rivet or a bottom solid rivet.
8. The molding die for a C-shaped half frame bracket of an automobile safety belt according to claim 1, wherein: under the action of the adjustable jackscrew and the lower ejector pin, protruding thorn can be avoided from being generated at the center of the bottom surface of the rivet with the solid bottom: when the rivet to be riveted adopts the rivet with the solid bottom, the spacing between the adjustable jackscrews and the bottom end of the lower ejector pin is adjusted by adjusting the screwing-in depth of the adjustable jackscrews, so that the limit position of the lower ejector pin to be compressed is limited, when the lower ejector pin is compressed to the limit position, the top of the lower ejector pin is flush with the top surface of the lower rivet head, and protruding thorns are avoided from being generated on the bottom surface of the rivet with the solid bottom during riveting.
9. The molding die for a C-shaped half frame bracket of an automobile safety belt according to claim 1, wherein: an upper rivet is vertically arranged in the upper die holder, an upper thimble is vertically arranged in the upper rivet in a sliding manner, a spring for providing downward elasticity for the upper thimble is arranged, a transverse detection hole is formed in the top of the upper thimble, a detection switch is arranged in the transverse detection hole, the bottom end of the upper thimble is exposed out of the upper rivet in a natural state, and the top end of the upper thimble is not inserted into the transverse detection hole; when the upper die part moves downwards, the bottom end of the upper thimble contacts the top of the rivet with rivet and then is jacked upwards, so that the top end of the upper thimble is inserted into the transverse detection hole, the detection switch is triggered, and whether the rivet is installed on the workpiece to be riveted is judged through the detection switch.
