Abstract
The utility model discloses a hot press for machining composite fiber boards. The hot press comprises an upper board and an lower press board; an electric heating device is arranged on each of the upper and lower press boards; heat conducting oil passages are uniformly distributed in the upper and lower press boards; the side walls of the upper and lower press boards are respectively provided with an oil inlet and an oil return opening which are communicated with the heat conducting oil passages. As the heat conducting oil is adopted to absorb the heat and moderate the surface temperature of a heat transferring balance board, the heat processing and forming effect of the composite fiber board is improved, and the product defects caused by excessively heating and carbonizing the board and insufficiently processing the board at low temperature are avoided; at the same time, the heat energy is slowly released through the heat conducting oil, and the electrical energy is saved.
Description
Technical field
The utility model relates to a kind of hot press of producing composite fiber plate.
Background technology
Composite fiber plate is widely used in the base material of automotive interior material.Its production process is normally hot-forming with fibrofelt with hot press.The upper and lower pressing plate of this hot press is provided with electric heater unit, makes clamp surface reach certain temperature by electrical heating, makes pressing plate heat fibrofelt in pressurization, makes chemical fibre in the fibrofelt be heated and dissolves the formation viscose glue.This electric heater unit is generally electrothermal tube, because electric heating tube is uniform to be installed in the pressing plate, the difference of position between the electrothermal tube and the every actual caloric value of electrothermal tube, cause the clamp surface temperature inconsistent, cause institute pressed sheet surface the too high carbonization of temperature to occur, it is insufficient the hot-working of temperature low production perhaps to occur, influences product quality.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art part, and a kind of hot press is provided, and clamp surface heat conduction is even, can improve the quality of hot-pressed board.
To achieve these goals, this is practical to have adopted following scheme: comprise upper and lower pressing plate, on the upper and lower pressing plate electric heater unit is housed, is provided with equally distributed heat conduction oil circuit in the upper and lower pressing plate, be respectively equipped with oil-in and the oil return opening that communicates with the heat conduction oil circuit on the upper and lower pressing plate sidewall.The heat of the conduction oil absorption pressure plate hight warm area in the pressing plate also passes to low-temperature space, makes that the temperature in the pressing plate is tending towards evenly, thereby can improve the quality of hot-pressed board.
A preferred version of the present utility model is that the electric heating oil circuit is arranged on adding between pressure surface and the electric heater unit of upper and lower pressing plate, can make the pressurization surface temperature of pressing plate more even.
As shown from the above technical solution, the utility model adopts the heat absorption of thermal conductance oil, relaxes the balanced clamp surface temperature of conducting heat, and has improved composite fiber plate thermo forming effect, has avoided overheated carbonization of sheet material and the inadequate product defects of low temperature process; Simultaneously, with the heat energy slowly-releasing, saved electric energy by conduction oil.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is along A-A line profile among Fig. 1.
The specific embodiment
Shown in 1 figure, the lower platen 3 of hot press is supported on the base 4, and top board 2 is fixed on cylinder 1 below, on the upper and lower pressing plate 2,3 a plurality of electrothermal tubes 5 is housed all.
Have the heat conduction oil circuit in the upper and lower pressing plate 2,3, this heat conduction oil circuit is arranged on the zone between pressure surface 23,33 and the electrothermal tube 5 of adding of upper and lower pressing plate 2,3.Figure 2 shows that the conduction oil line structure of lower platen 3, vertical passage 36 that the conduction oil route is parallel and horizontal channel 35 compositions that adjacent two vertical passages are communicated with, vertical passage 36 is formed by the through hole of pressing plate 3 one sides processing, the through hole two ends are provided with capping 34, horizontal channel 35 is located at capping 33 inboards, and the vertical passage of pressing plate 3 both sides respectively has a port to be respectively oil-in 31 and oil-out 32.
Heat conduction oil circuit in the top board 2 is identical with lower platen 3 heat conduction oil circuits, has oil-in 21 and oil-out 22 on top board 2 sidewalls.
During work, by getting final product in the heat conduction oil circuit in the upper and lower pressing plate of oil-in 21,31 importings, the gas in the heat conduction oil circuit is discharged by oil- out 22,32 with conduction oil.
Claims (2)
1. hot press, comprise upper and lower pressing plate (2,3), upper and lower pressing plate is equipped with electric heater unit on (2,3), its characteristic is: upper and lower pressing plate is provided with equally distributed heat conduction oil circuit in (2,3), is respectively equipped with the oil-in (21,31) and the oil return opening (22,32) that communicate with the heat conduction oil circuit on upper and lower pressing plate (2, the 3) sidewall.
