Description

Technical Field

[0001] The utility model relates to the field of foaming molding machines, in particular to a graphene heating plate and a foaming molding machine. Background Art

[0002] The midsole of the shoe sole is divided into traditional midsole, IP injection midsole and supercritical nitrogen foaming midsole. The traditional midsole is usually formed by a secondary foaming molding machine, that is, the granular raw materials are introduced into the mold and foamed once on a small foam machine to produce a blank, and then the finished midsole is formed by a secondary foaming molding machine.

[0003] The heating elements used in the vulcanization heating device of the existing secondary foaming molding machine are all tubular. When the electric heating tube is inserted into the hole of the hot plate, it is difficult for the electric heating tube to be in close contact with the inner wall of the hole, so the thermal efficiency is low, the temperature rise is slow, and the temperature difference on the surface of the hot plate is large;

[0004] Alternatively, the heating device uses heat-conducting oil to generate heat, and includes a first support plate, a second support plate, an oil pipe and a heat cylinder. The heat cylinder is used to store heat-conducting oil, and the oil pipe is connected to the heat cylinder. The oil pipe is arranged between the first support plate and the second support plate, and the first support plate and the second support plate are locked by a locking piece. The oil pipe is used to provide a heat source for the first support plate and the second support plate. This method of heating with an oil pipe causes the pipeline to occupy a large space around the heating device, which increases the overall volume of the heating device. In addition, the heat conduction structure is relatively complex, and the oil pipe is inconvenient to replace due to its own structure.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0015] As a preferred solution, two heating plates are provided and spaced apart from each other, and at least one heating plate is driven by the first driving device to move up and down.
