The molten materials initially arrive at the position below the extrusion pipe and cannot cover all the extrusion holes of the extrusion plate, which will cause the plastic shape passing through the extrusion plate initially to be irregular, resulting in the loss of molten raw materials.

[0036] Referring to Figures 1-10 The utility model provides a kind of high frequency melting extrusion equipment for plastic product processing, including placing seat 1, the top of placing seat 1 is fixedly connected with extrusion channel 8, and one end of extrusion channel 8 is fixedly connected with extrusion plate 6, placing seat 1 is fixedly connected with driving motor 2 at the other end of extrusion channel 8, the output shaft of driving motor 2 is fixedly connected with conveying long shaft 10 by coupling, the outer side wall of conveying long shaft 10 is fixedly connected with spiral conveying blade 9, and the inner wall of both sides of extrusion channel 8 close to extrusion plate 6 is opened with installation groove 11, and two installation grooves 11 are equipped with concentration through module 12 inside, concentration through module 12 includes two concentration baffle 1201, two concentration baffles 1201 are connected by hinge on the inner wall of both sides of extrusion channel 8, two concentration baffles 1201 contact, and the same side of two concentration baffles 1201 is opened with fixed slot 1216, and the inner side wall of fixed slot 1216 is fixedly connected with pressure sensor 1214 at equal distance, and the inner wall between every two pressure sensors 1214 of fixed slot 1216 is fixedly connected with filling rod 1202.
