The invention discloses a hot melting dismantling jig which comprises a framework, a first driving device, a second driving device, vacuum suction disks, a hot melting platform and a heating platform, wherein the vacuum suction disks are fixedly connected with the heating platform, and the vacuum suction disks and the heating platform can longitudinally move and are positioned on the upper side of the framework; the hot melting platform can longitudinally move and is positioned on the lower side of the framework; a positioning device for fixing products to be dismantled is arranged on the hot melting platform; the vacuum suction disks are opposite to the positions of the products on the hot melting platform; the heating platform is of a framework structure and can be just pressed against the edges of the products on he hot melting platform; a heating device is arranged in the heating platform; the first driving device and the second driving device respectively drive the vacuum suction disks and the hot melting platform to move. The hot melting dismantling jig can quickly and conveniently dismantle a display screen of an electronic product; the working efficiency is effectively improved; the labor cost and the raw material cost of a company are lowered, and the hot melting dismantling jig is safe to use.
