Description
Technical field
The present invention relates to the hot plate of a kind of one side heat transfer electrical heating press hot plate, particularly a kind of electrical heating press hot plate, electrical heating elements chamber and heat-insulating base.
Background technology
In the production process of some products, electricity consumption heated press to apply pressure to product and conduct heat to product.Rubber plate vulcanization machine is a kind of typical electrical heating press.Electrical heating press has vertical frame, vertical solution cylinder pressure is arranged at framework bottom, and the location, top in framework is connected with press hot plate, and the upper plunger bar of hydraulic cylinder is connected with lower press hot plate, press hot plate is the vitals of electrical heating press, and upper press hot plate is identical with lower press hot plate.The upper and lower press hot plate of rubber plate vulcanization machine is for clamping the mould of molded rubber product.During use, electricity consumption heated press hot plate to mould heat transfer, drive press hot plate to mould transmission of pressure with vertical solution cylinder pressure, after keeping the regular hour, allows the sizing material in mold cavity be sulfided into rubber under certain temperature and pressure.
In prior art, the press hot plate of electrical heating press is hexahedron steel plate, hexahedron steel plate has upper and lower plate face and four, front, rear, left and right lateral plates, electrical heating elements chamber is evenly equipped with in hexahedron steel plate, electrical heating elements chamber is distributed on duct parallel to each other parallel with upper and lower plate face in hexahedron steel plate, and duct is embedded with the electrical heating elements of strip.
After the press hot plate of electrical heating press is heated, all outwards conduct heat in six faces of hexahedron steel plate.During actual use, only have a plate face to be outwards do useful heat transfer in six plate faces of steel plate, other five plate faces do useless heat transfer to environment and vertical frame.
Useless heat transfer is done to environment and vertical frame in order to reduce, in Chinese patent literature 103950132A, disclose a kind of one side heat transfer electrical heating press hot plate, the heat transfer plate that the useful bolt of this press hot plate is connected and heat-insulating base, heat transfer plate is rectangular steel plates, heat-insulating base is the fiberglass reinforced plastics rectangular channel matched with heat transfer plate, heat transfer plate is embedded in fiberglass reinforced plastics rectangular channel, the bottom land of fiberglass reinforced plastics rectangular channel is evenly equipped with the groove that cross section parallel to each other is rectangle, the heat transfer plate lower face at groove port place is connected with electrical heating elements, electrical heating elements is strip plate shape electric heating sheets.Because heat transfer plate is embedded in the lower fiberglass reinforced plastics rectangular channel of thermal conductivity factor, during use, heat transfer plate only has upper face to do useful heat transfer, greatly reduces other plate Environment Oriented and the useless heat transfer of vertical frame, makes power consumption of the present invention lower
The press hot plate of this electrical heating press still has following deficiency:
1. electrical heating elements is strip plate shape, strip plate shape electrical heating elements is embedded in electrical heating elements chamber, the duct of to be cross section that the lower face of groove at the bottom of bottom tub and heat transfer plate forms be in electrical heating elements chamber rectangle, after assembling, strip plate shape electrical heating elements only has a face to be against on heat transfer plate, another five faces are in the groove at the bottom of bottom tub, base thermal conductivity factor is lower, during use, the heat that strip plate electrical heating elements sends below can not pass on heat transfer plate well, makes heat utilization efficiency not be very high;
2. heat transfer plate be embedded in base rectangular channel in after, heat transfer plate and the contact area at the bottom of bottom tub are comparatively large, although the thermal conductivity factor of fiberglass reinforced plastics base is lower, due to contact area comparatively greatly, too increase useless heat transfer.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, proposing the one side heat transfer electrical heating press hot plate that higher, the useless heat transfer of a kind of heat utilization efficiency is lower.
The present invention is achieved using the following method.
The heat transfer plate that the useful bolt of one side heat transfer electrical heating press hot plate is connected and heat-insulating base, heat transfer plate is rectangular steel plates, and heat-insulating base is the fiberglass reinforced plastics rectangular channel matched with heat transfer plate, and heat transfer plate is embedded in fiberglass reinforced plastics rectangular channel,
Heat transfer plate is the complex heat transfer plate be composited by upper and lower two-layer rectangular steel plates, the electrical heating elements chamber that cross section parallel to each other is rectangle is evenly equipped with between the upper strata rectangular steel plates of complex heat transfer plate and lower floor's rectangular steel plates, electrical heating elements chamber is embedded with strip plate shape electrical heating elements, and the bottom land of fiberglass reinforced plastics rectangular channel has by the uniform contour column of ranks.
During installation, according to the press that will install, at heat transfer plate lower face fabrication and installation screw of the present invention, the installing hole that manufacture and installation screw communicates at the bottom of rectangular channel, is arranged on the present invention on press.
During use, heat transfer plate of the present invention only has upper face to do useful heat transfer, is a kind of one side heat transfer electrical heating press hot plate.
Strip plate shape electrical heating elements of the present invention is in the electrical heating elements chamber in complex heat transfer plate, and the heat that the above and below of strip plate shape electrical heating elements sends all passes on complex heat transfer plate, and heat utilization efficiency is higher; Complex heat transfer plate is embedded in after in fiberglass reinforced plastics rectangular channel, the bottom land that is against fiberglass reinforced plastics rectangular channel below complex heat transfer plate by the uniform contour column of ranks, complex heat transfer plate and the contact area at the bottom of bottom tub less, useless heat transfer can be reduced.
Below in conjunction with accompanying drawing, the present invention is further described.
