Problems solved by technology

The electric heating device is usually an electric heating tube. Since the electric heating tubes are evenly installed in the pressing plate, the position between the electric heating tubes and the difference in the actual heat generated by each electric heating tube will cause the surface temperature of the pressing plate to be inconsistent, resulting in the surface of the pressed plate. Carbonization at too high a temperature, or insufficient thermal processing of products at a low temperature will affect product quality

Embodiment Construction

[0009] As shown in Figure 1, the lower platen 3 of the hot press is supported on the base 4, the upper platen 2 is fixed below the cylinder 1, and a plurality of electric heating tubes 5 are installed on the upper and lower platens 2,3.

[0010] The upper and lower platens 2, 3 are provided with heat conduction oil passages, and the heat conduction oil passages are arranged in the area between the pressing surfaces 23, 33 of the upper and lower platens 2, 3 and the electric heating tube 5. figure 2 Shown is the heat conduction oil circuit structure of the lower platen 3. The heat conduction oil route is composed of a parallel longitudinal channel 36 and a horizontal channel 35 connecting two adjacent longitudinal channels. The longitudinal channel 36 is formed by a through hole processed on one side of the platen 3. Both ends of the hole are provided with a cover 34, and a horizontal passage 35 is located inside the cover 33. The longitudinal passages on both sides of the pres...

Abstract

The invention discloses a hot press used for processing a composite fiber plate, which comprises an upper press plate and a lower press plate, wherein the upper press plate and the lower press plate are provided with an electric heating device; the upper press plate and the lower press plate are internally provided with uniformly distributed heat conduction oil paths; and the side walls of the upper press plate and the lower press plate are respectively provided with an oil inlet and an oil return port which are communicated with the heat conduction oil paths. In the invention, heat conduction oil is adopted to absorb heat, relieve the heat transfer and balance the surface temperature of the press plates, so that the hot processing and molding effects of the composite fiber plate are improved, and the product defects of plate edge superheating and carbonization and insufficient low-temperature processing are overcome; and meanwhile, heat energy is slowly released through the heat conduction oil, thereby electric energy is saved.

Description

technical field [0001] The invention relates to a hot press for producing composite fiber boards. Background technique [0002] Composite fiberboard is widely used as a base material for automotive interior materials. Its production process usually uses a hot press to heat-press the fiber mat. The upper and lower platens of this hot press are equipped with electric heating devices, and the surface of the platen reaches a certain temperature through electric heating, so that the platen heats the fiber mat while pressing, so that the chemical fibers in the fiber mat are heated and melted to form Viscose. The electric heating device is usually an electric heating tube. Since the electric heating tubes are evenly installed in the pressing plate, the position between the electric heating tubes and the difference in the actual heat generated by each electric heating tube will cause the surface temperature of the pressing plate to be inconsistent, resulting in the surface of the ...
