Description

Technical Field

[0001] The utility model relates to the technical field of mold equipment, in particular to a mold heating electromagnetic cover. Background Art

[0002] Tire molds are molds used for vulcanization molding of various tires. Tire molds mainly include flexible molds, which include an upper mold plate, the inner surface edge of the upper mold plate is tightly attached to a mold pattern block, the outer side of the mold pattern block is provided with a middle mold sleeve assembly, the inner side of the middle mold sleeve assembly is tightly attached to a lower mold plate, the surface of the lower mold plate is tightly attached to the mold pattern block, and a vulcanizer center mechanism is provided at the central axis of the upper mold plate and the lower mold plate.

[0003] The electromagnetic heating method is that a high-frequency and high-voltage current with high speed changes flows through the coil, which will generate a high-speed changing alternating magnetic field, cut the alternating magnetic lines of force and then act on the mold sleeve to generate alternating current (i.e. eddy current). The eddy current causes the carriers inside the mold sleeve metal to move irregularly at high speed, and the carriers collide and rub against each other to generate heat energy. Thus, the heating effect is achieved. That is, by converting electrical energy into magnetic energy, the heated steel body generates induced eddy currents, which is a heating method.

[0004] The electromagnetic heating method for the flexible mold is as follows: an electromagnetic cover is added to the periphery of the middle mold, which is composed of an electromagnetic cover insulation board. The electromagnetic coils led by the electromagnetic controller are wrapped around the inner plate frame of the electromagnetic cover. The eddy current generated by the electromagnetic coil acts on the middle mold to heat the middle mold, and the heat is transferred to the flower block. Thus, the flexible mold is heated. For this kind of electromagnetic cover, the number of windings, spacing and size of the electromagnetic coil directly affect the heating effect. At the same time, if the electromagnetic coil is not limited, the position will change during use, affecting the heating stability and effect. Utility Model Content

[0025] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0026] See also Figures 1 to 3 The utility model provides a mold heating electromagnetic cover, including a wire storage box 100, a cover plate 200 and a limit plate 300.

[0027] Specifically, the wire storage box 100 is arranged outside the middle mold sleeve 1, and the side of the wire storage box 100 away from the middle mold sleeve 1 is open. The cover plate 200 is covered on the wire storage box 100. There are multiple limiting plates 300, and the multiple limiting plates 300 are arranged in a ring shape from top to bottom in the wire storage box 100, and the electromagnetic coil 2 can be fixed between adjacent limiting plates 300.

[0028] When in use, the electromagnetic coil 2 is clamped between the limiting plates 300. The limiting plates 300 limit the electromagnetic coil 2, which can prevent the electromagnetic coil 2 from changing its position in the wire storage box 100 and affecting the heating effect.

[0029] As a preferred embodiment, each limiting plate 300 is movably connected to the wire storage box 100, and the limiting plate 300 can move up and down, so as to adapt to electromagnetic coils 2 of different diameters.

[0030] In this embodiment, the mold heating electromagnetic cover further includes a position adjustment mechanism 400, which is disposed on the wire storage box 100 and connected to all the limit plates 300, and can drive the limit plates 300 to move up and down, thereby realizing the position adjustment of the limit plates 300.

[0031] Specifically, the position adjustment mechanism 400 includes a linear motion source 410, a mounting plate, a driving plate 420 and a guide rod 430. There are two mounting plates, which are arranged oppositely and spaced apart in the wire storage box 100, and the guide rod 430 is arranged vertically. There are multiple guide rods 430, which are fixed between the two mounting plates in parallel and spaced apart uniformly, and each guide rod 430 can slide through all the limit plates 300.

[0032] The driving plate 420 is arranged on one side of the wire storage box 100 close to the inner bottom surface thereof, and the linear motion source 410 is connected to the driving plate 420, and can drive the driving plate 420 to move horizontally. The driving plate 420 is provided with a plurality of guide grooves 421, and the plurality of guide grooves 421 are symmetrical up and down, and the guide groove 421 located in the middle is arranged corresponding to the middle limit plate 300. The ends of the same end of the guide grooves 421 on both sides are arranged to be close to and tilted toward the middle direction, and the tilt angle of each guide groove 421 increases in an arithmetic progression, and each limit plate 300 is slidably connected to a guide groove 421 through an insertion rod 440.

[0033] During use, when the linear motion source 410 is started, the driving plate 420 can be pushed to move horizontally. Through the cooperation of the insertion rod 440, the guide groove 421, and the guide rod 430, the limit plate 300 can be driven to spread out or gather to both sides, thereby adjusting the distance between the two limit plates 300 and simultaneously realizing the limitation of electromagnetic coils 2 of different diameters.
