The utility model provides a heating brick of a plastic-suction machine. The heating brick is characterized in that: the heating brick adopts the electromagnetic induction heating and is provided with an electromagnetic coil and a heating plate; the electromagnetic coil which adopts a high-frequency power supply as a working power supply is used for generating a high-frequency alternating magnetic field, and the heating plate which generates heat through electromagnetic induction is arranged in the high-frequency alternating magnetic field generated by the electromagnetic coil. As to the specific application in the plastic-suction machine, a heating component is directly heated by a vortex on the basis of the principle of electromagnetic induction; with certain directionality, the above heating method effectively restrains ineffective heat radiation towards the peripheral space. Compared with the resistance type heating brick of the plastic-suction machine, the heating brick in the utility model increases the
