[0025] The above structure can pre-position and fix IML mold through the positioning mechanism, and aligns the pattern base material by using adsorption seat 8, because IML technology is to put the film with printed pattern into injection mold, then inject plastic on the back of the film, so that plastic and film are tightly combined together to form the final product, so the positioning mechanism uses three layers of positioning to position respectively.

[0028] Further, the inner part of the positioning assembly 6 comprises an adjusting cylinder 601, a connecting frame 602 and a positioning arm 603, the outer wall of the rack 1 is provided with the adjusting cylinder 601, the output end of the adjusting cylinder 601 is connected with the connecting frame 602 through a rotating shaft, one side of the connecting frame 602 is connected with the positioning arm 603 through a rotating shaft, the positioning assembly 6 is arranged at both sides of the IML mold cavity 7, and the positioning arm 603 is located above the adsorption seat 8.
[0029] The above structure drives the positioning arm 603 to rotate around the connecting frame 602 through the adjusting cylinder 601, so as to position the upper part of the mold.
[0030] Further, the transmission belt 4 is located below the IML mold cavity 7, the inner part of the IML mold cavity 7 is clamped with an IML mold set, the inner part of the air connector 10 is provided with a thread, and the connecting pipe 9 is connected with the air hole of the adsorption seat 8.
