Description

Technical Field

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

[0002] Electromagnetic induction heater is a heating controller manufactured based on the principle of electromagnetic induction heating. The principle of electromagnetic induction heating is that the alternating current generated by the induction heating power source generates an alternating magnetic field through the inductor (i.e., coil), and the magnetic conductive object is placed in it to cut the alternating magnetic field lines, thereby generating alternating current (i.e., eddy current) inside the object. The eddy current makes the atoms inside the object move irregularly at high speed, and the atoms collide and rub against each other to generate heat energy, thereby achieving the effect of heating the object. That is, a heating method that converts electrical energy into magnetic energy so that the heated steel body is induced by magnetic energy and generates heat.

[0003] Electromagnetic induction heaters can preheat molds, but some molds are long. During preheating, the mold is clamped by an assembly structure, and the electromagnetic coil is controlled to move relative to the mold to heat the entire length of the mold. However, when the electromagnetic coil is always moving during heating, the preheating effect on the mold is poor. Therefore, a mold preheating electromagnetic induction heater is proposed.

[0013] (III) Beneficial effects

[0014] The utility model provides a mold preheating electromagnetic induction heater, which has the following beneficial effects:

[0015] 1. The mold preheating electromagnetic induction heater is provided with a tooth plate and a half-tooth gear. When the motor drives the half-tooth gear to rotate, the tooth part of the half-tooth gear intermittently meshes with the tooth plate. When the half-tooth gear is disengaged from the tooth plate, the electromagnetic coil device stops meshing with the mold relative to heat it stably. When the half-tooth gear is meshed with the tooth plate, the electromagnetic coil device is driven to move relative to the mold, changing the mold preheating position, and fully preheating the clamped mold during the intermittent movement.

[0016] 2. The mold preheating electromagnetic induction heater is provided with a tooth block, a reset spring, a threaded rod, a pull rope and a push rod. When the mounting frame moves, the tooth block is driven to continuously compress and push the telescopic rod. When the half-tooth gear is disengaged from the tooth plate, the tooth block stably limits the position of the mounting block by engaging with the tooth plate. After the mounting frame moves to the rearmost and the mold is fully preheated, the push rod at the rear pushes the rear movable rod to pull the pull rope at the rear. The pull rope drives the threaded rod to engage, and the conveyor belt causes the two threaded rods to rotate synchronously. The tooth plate moves to the right by engaging with the threaded rod and disengages from the tooth block. The mounting frame moves forward under the push of the reset spring, so that the electromagnetic coil device resets forward and automatically disengages from the mold.
