At present, electric heating tubes are generally used to heat the mold for mold preheating;

[0003] At present, most of the electric heating tubes on the market are fixed on the mold by using elliptical flange fixing plates. However, since the traditional elliptical flange fixing plates are directly welded to the electric heating tubes and cannot rotate relative to the electric heating tubes, when the position of the mold hole changes, it is difficult to align the elliptical flange fixing plates with the mold holes. The flexibility is not high, which easily causes the elliptical flange fixing plates of the heating tubes to be unable to be fixed with the mold holes. The electric heating tubes are difficult to install. In addition, the weight of the electric heating tubes is heavy, which will increase the labor intensity and energy of the staff.
