Abstract
The utility model relates to heating devices for a hot-press graphite die. The die consists of an upper die and a lower die, wherein the lower die comprises a die plate, a die cavity, a die core and a heating device; the upper die comprises a die plate, a die core and a heating device; electric heating pipes are used as the heating devices and are respectively arranged in a die plate groove in the periphery of the die cores of the upper and lower dies; positioning is carried out through die core fixing plates. The heating devices of the hot-press graphite die are simple in structure, service life is greatly prolonged, the service life of the electric heating pipes exceeds 6 months, the problem that the die is frequently changed is solved, efficiency is improved, quality is promoted, labor intensity is reduced, and the difficulty in a manufacturing process is solved.
Description
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of hot pressing graphite jig heater, is used for seal and manufactures.
Background technology
The main movable ring part of seal product that my company produces is graphite, and is by graphite jig, that graphite powder is hot-forming.Graphite jig was all electric-heating-wire-heatings in the past, during the dress mould, heating wire cover insulation small porcelain tube is contained in mould, but such device is short service life, and heating wire falls through normal off, and the service life of a new heating wire is only in the two weeks left and right, thereby to often to change heating wire, one gets a dress, adds the cooling heating-up time, loses time, strengthened intensity of workers, staffing effectiveness is not high.
The utility model content
The utility model, for the problems referred to above, provides a kind of hot pressing graphite jig heater, and its purpose is: change heating wire into the electrothermal tube heating, improve service life and operating efficiency.
Technical solution of the present utility model:
A kind of hot pressing graphite jig heater, mould is comprised of upper die and lower die, counterdie comprises template, die cavity, core rod, heater, patrix comprises template, core rod, heater, it is characterized in that: described heater is electrothermal tube, described electrothermal tube respectively is placed in the template groove of upper and lower mould core rod periphery, by the core rod fixed head, locates.
Described electrothermal tube is W shape electrothermal tube.
The main material of described electrothermal tube is stainless steel, and the stainless steel thermal efficiency is high, and heating evenly, when having electric current to pass through in the high temperature resistance silk, the heat energy of generation spreads to metal surface by the crystal magnesium oxide powder, then is transmitted on mould, be transmitted on graphite powder by mould again, make it hot-forming.
Described electrothermal tube comprises electrothermal tube body, lead-in wire rod and power supply, and wherein, the lead-in wire rod is placed in electrothermal tube body two ends, and power supply is controlled by control device, and described control device, power supply become series loop by wire with the lead-in wire clavate at electrothermal tube body two ends.
Described control device is temperature controller.
Further, described electrothermal tube outside is equipped with temperature sensor, and described temperature sensor is connected with the temperature controller input.
Further, display unit also is installed on described temperature controller, described display unit is connected with temperature sensor.
Described display unit is LCD.
The beneficial effects of the utility model:
The utility model is simple in structure, and greatly extend service life, and electrothermal tube service life was over 6 months, often not only solve the more problem of mold exchange, improved simultaneously efficiency, promoted quality, reduce employee's labour intensity, solved the difficult problem in the manufacture process.
Description of drawings
Fig. 1 is the utility model electrothermal tube position assumption diagram.
Fig. 2 is the utility model electrothermal tube connection diagram.
The specific embodiment
Illustrate the utility model below in conjunction with drawings and Examples.
As shown in Figure 1 to Figure 2, a kind of hot pressing graphite jig, formed by upper die and lower die, counterdie comprises template, die cavity, core rod and electrothermal tube, patrix comprises template, core rod and electrothermal tube, described electrothermal tube 3 respectively is placed in template 2 grooves of core rod periphery of upper and lower mould, then by core rod 1 fixed head location.(groove consistent with the electrothermal tube shape is arranged respectively on the mould upper and lower bottom plate.) described electrothermal tube 3 is W shape electrothermal tube, material is stainless steel, this structure thermal efficiency is high, heating evenly, when having electric current to pass through in the high temperature resistance silk, the heat energy of generation spreads to metal surface by the crystal magnesium oxide powder, then is transmitted on mould, be transmitted on graphite powder by mould again, make it hot-forming.
As shown in Figure 3, electrothermal tube comprises electrothermal tube body 3-1, the excellent 3-2 of lead-in wire and power supply 3-4, wherein, the excellent 3-2 that goes between is placed in electrothermal tube body 3-1 two ends, power supply 3-4 controls by temperature controller 3-3, and described temperature controller 3-3, power supply 3-4 form series loop by the lead-in wire rod 3-2 at wire and electrothermal tube body two ends.Electrothermal tube body 3-1 outside is equipped with temperature sensor 3-5, and temperature sensor 3-5 is connected with temperature controller 3-3 input.On described temperature controller 3-3, LCD display devices 3-6 also is installed, LCD display devices 3-6 is connected with temperature sensor 3-5.Electrothermal tube is controlled temperature by temperature controller, and when temperature sensor 3-5 detected the electrothermal tube temperature overheating, stopped heating, when temperature is too low, was communicated with power supply 3-4 and heats, and realizes that temperature controls automatically.
The utility model heats graphite jig by electrothermal tube, and electrothermal tube has often solved the more problem of mold exchange much larger than resistance wire service life, can effectively increase work efficiency, and reduces employee's labour intensity.
To sum up, the utility model produces a desired effect.
