The invention discloses an auxiliary component for preventing the mold jam of a mute terminal machine. The component comprises a machine body (1), and a lubrication sensing module (2), a tool isolation module (3), an information receiving module (4) and a management module (5), which are arranged on the machine body (1); when in operation, the lubrication sensing module (2) senses the condition of lubrication operation on a mold, the tool isolation module (3) isolates the harm of a riveting knife to a terminal, the information receiving module (4) receives relevant information, and the management module (5) processes comprehensive information; an addition recording module (6) is arranged on the lubrication sensing module (2), for recording the number of times of the lubrication operation on the mold; a pressure sensing module (7) is arranged on the tool isolation module (3), for sensing the generated pressure condition of the riveting knife when the riveting knife contacts the terminal; a prompting module (8) is arranged on the management module (5); and by periodically lubricating the mold, the mold jam is avoided and thus the operation effect is not affected.
