Description

Technical Field

[0001] The present application belongs to the technical field of foam molds, and in particular relates to a heating device for a foam mold. Background Art

[0002] The mold for foaming is a plastic foaming mold. The foaming resin is directly filled into the mold, which is heated and melted to form a gas-liquid saturated solution. Through nucleation, a large number of tiny bubble nuclei are formed, and the bubble nuclei grow to form foam plastic parts. There are three commonly used foaming methods: physical foaming, chemical foaming and mechanical foaming.

[0003] A patent document CN206048653U was retrieved, which disclosed a heating device for a foam mold, including a steamer and an air inlet pipe for heating the foam mold, wherein the steamer is connected to the air outlet of the boiler through the air inlet pipe, and the water tank in the boiler is also connected to the steamer through a drainage pipe, wherein the connection end of the air inlet pipe and the steamer is located at the upper side of the steamer, and the connection end of the drainage pipe and the steamer is located at the lower end of the steamer, and the drainage pipe is provided with a water pump and a first valve with the infusion direction from the steamer to the boiler. By arranging a drainage pipe between the steamer and the boiler, after the steam is converted into hot water in the steamer, it can be discharged into the water tank of the boiler through the drainage pipe and then be reheated to be steam for repeated use, thereby avoiding the waste of heat energy and achieving the effect of energy saving and emission reduction.

[0004] However, the inventors have discovered that this technical solution still has at least the following defects:

[0005] When the equipment heats the foam mold with steam, the steam delivery direction and the mold body are fixed. The side close to the steam inlet is obviously heated faster and has a higher temperature. The foam mold is heated very unevenly, and the heating box cannot be insulated. It heats slowly in an environment with low external temperature. Utility Model Content

At the same time, the hot air inside the heating device box 1 can be transported to the inside of the outer box body 101 through the thermal insulation structure 6 to keep the heating device box 1 warm.

The electromagnetic heating plate 203 is electrically connected through the power controller 201 and the connecting wire 202, so that the alternating electromagnetic field generated by the electromagnetic current in the coil induces eddy currents inside the induction device. The eddy currents quickly generate heat under the high-frequency alternating electromagnetic field, and then the heating plate is heated through conduction.
