Rectangular base plate between have mica sheet,
Have gap between inner panel upper face adjacent grooves parallel to each other, from the middle of combined steel plate to two side peripheries,
Gap between adjacent grooves is gradually reduced,
The electrical heating elements are Wound-rotor type electrical heating elements, and electrical heating elements have and the fit depressions on combined steel plate
Strip housing, have strip insulation board in housing, individual layer resistance wire is wound with insulation board, individual layer resistance wire on insulation board
Adjacent turn-to-turn has gap, and from the centre of insulation board to two ends, the gap of adjacent turn-to-turn is gradually reduced.
During installation, two pieces of present invention are taken, one piece is press hot plate up, another piece is press hot plate in lower section,
With screw rod by installing the mounting hole on steel plate, press hot plate up is arranged in the vertical frame of electrical heating press
Top, being arranged on the upper plunger bar of hydraulic cylinder in the press hot plate of lower section, allow press hot plate up with
The heat transfer plate of the press hot plate of side is relative, and temperature sensor is inserted into the temperature sensor jack of heat transfer plate, is assembled into electricity and adds
Hot press.
When using, electrical heating elements are communicated with power supply, the heating of press hot plate, the article for needing to pressurize, heating put
Between two blocks of hot plates of the invention of electrical heating press, pressure, electricity consumption heating element heats heat are applied to article with hydraulic cylinder
Plate, heat transfer plate can transmit heat to article.
The present invention has following beneficial effect：
1. heat transfer plate is embedded in square groove shape heat-insulating base, after heat transfer plate is embedded in square groove shape heat-insulating base, only upper plate
Show outside groove, for used as useful heat transfer, the lower face of hot plate and four lateral plates to be in the relatively low square groove of thermal conductivity factor
In shape heat-insulating base, the useless heat transfer to environment and vertical frame is greatly reduced, be a kind of electrical heating pressure of one side heat transfer
Machine hot plate, power consumption of the invention is smaller.
