DETAILED DESCRIPTION OF THE INVENTION

[0032] The object of the present invention is a cartridge heater 1 cover.

[0033] As can be seen in the figures, the cover has a metal plate 2, which couples to the end of the cartridge heater 1 wherefrom the wiring 3 protrudes. The cover has a threaded through hole 4 in the plate 2. The metal plate 2 is joined to the end of the cartridge heater 1 by welding to the outer sheath of said cartridge heater 1.

[0034] With this configuration, the removal of the cartridge heater 1 from the cavity of the mold 6 or body wherein it is inserted can be carried out by using a screw 7 or any threaded rod having the same measurements as the through hole 4 of the plate 2. The screw 7 or threaded rod is threaded into the hole 4 of the plate 2, and once inserted, it is used as a handle to comfortably pull and remove the cartridge heater 1 from the mold 6, thereby preventing any damage thereto. FIG. 6 shows a screw 7 coupled to a cartridge heater 1 with the cover object of the present invention. FIG. 7 shows a cartridge heater 1 inserted into a cavity of a mold 6 or body, with the cover object of the invention and a screw 7 coupled thereto for its removal from the cavity of the mold 6 or body.

[0035] Preferably, as can be seen in FIGS. 2 and 3, the plate 2 has a circular shape to adapt to the shape of the end of the outer sheath of the cartridge heater 1, if this cartridge has a circular section, although it could have other shapes, such as for example, square or rectangular to adapt to tubes of said sections, or any other shape as long as it facilitates welding to the end of the sheath of the cartridge heater 1.

[0036] Likewise, the hole 4 is preferably centered on the plate 2, as seen in FIG. 3, to centralize the point of application of the force for removing the cartridge heater 1 and facilitating the same.

[0037] Given that the wiring 3 must project from the sheath of the cartridge heater 1 to be able to establish the electric connection, it will be possible to weld the plate 2 of the cover to the end of the sheath, leaving a space for the wiring 3 to come out. Alternatively, the plate 2 will at least have one opening 5 for the wiring 3 of the heater 1 to come out.

[0038] According to the foregoing, and according to a preferred embodiment of the invention, as can be clearly seen in FIG. 3, the plate 2 of the cover has two openings 5 for the wiring 3 to come out, one for each of the wires. Preferably, these two openings 5 are separated, and in the case of circular plates 2, they will be diametrically opposite from each other on the perimeter of the plate 2. This embodiment provides an even distribution, preventing the wires from tangling or from being too close together.
