Description
Technical field
The utility model is related to dieparts fields, more particularly to a kind of mold heating tube.
Background technology
During being molded or cast using mold, needs to preheat mold and meet production to reach and want
The condition of high temperature asked, to ensure the continuity of production and reduce rejection rate.
Current mold preheating generally heats mold using electric heating tube, but the sealing at existing electric heating tube both ends is not
Reliably, typically just apply insulating cement that the sealed piece that insulate is bonded in the end of heating tube, this design insulation sealed piece is easily de-
It falls, and non-refractory, under high-temperature situation, insulating part is easy to aging to lead to insulate sealed piece and electrothermal tube disengagement.
Invention content
Goal of the invention：In order to overcome the deficiencies in the prior art, a kind of sealing of the utility model offer is reliable, is resistant to
The high temperature resistant double end mold heating tube of high temperature.
Technical solution：To achieve the above object, the high temperature resistant double end mold heating tube of the utility model, including in heating
Pipe, the heating inner tube is arranged with heat conduction outer protection tube outside, and heats in inner tube and be provided with heating wire, and the both ends of heating wire respectively connect
There are one eduction rods；Two eduction rods are reached from the both ends of heating inner tube outside the heating inner tube respectively, the heating inner tube
Both ends by glass-dead seal, and silica gel is additionally provided on the outside of glass, glass is arranged at the inside of heating inner tube with silica gel.
Further, it is provided with screw thread on the excircle at the both ends of the heating inner tube, and be mounted on and the screw thread
The fixing nut of cooperation.
Further, in the heating inner tube insulating heat-conductive particle is also filled with except the heating wire.
Further, the heating wire spirals into spring shape.
Further, the screw pitch of the middle section of the heating wire of spring shape is larger, and the screw pitch of both ends part is smaller.
Further, the material of the heating wire is nichrome wire.
Further, the material of the heating inner tube is copper alloy, and the heat conduction outer protection tube is heavy wall stainless steel tube.
Further, the insulating heat-conductive particle is magnesia powder.
Advantageous effect：The both ends of the heating inner tube of the high temperature resistant double end mold heating tube of the utility model use glass and silicon
Glue is sealed, and glass is being heated with silica gel plug in inner tube so that the sealing two ends for heating inner tube are firm, use the sealing work
The heating tube of skill normal reliable can work under 500 degrees Celsius or more of hot environment, and service life can be greatly improved.
Description of the drawings
Attached drawing 1 is the structure chart of high temperature resistant double end mold heating tube.
Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings.
High temperature resistant double end mold heating tube as shown in Fig. 1, including heating inner tube 1, the heating inner tube 1 are arranged with outside
Heat conduction outer protection tube 2, and heat and be provided with heating wire 3 in inner tube 1, respectively there are one eduction rods 4 for connection at the both ends of heating wire 3；Two
Eduction rod 4 is reached from the both ends of heating inner tube 1 outside the heating inner tube 1 respectively, and the both ends of the heating inner tube 1 are by glass
5 sealings, and the outside of glass 5 is additionally provided with silica gel 6, glass 5 is arranged at the inside of heating inner tube 1 with silica gel 6.
It is provided with screw thread on the excircle at the both ends of the heating inner tube 1, and is mounted on and consolidates with the screw-thread fit
Determine nut 7.When installation, exterior part is pressed between the end of heat conduction outer protection tube 2 and fixing nut 7, it can be achieved that heating tube
It is reliably fixed.
In the heating inner tube 1 insulating heat-conductive particle is also filled with except the heating wire 3.Preferably, the insulation is led
Hot particle is magnesia powder.
In order to increase the length for the heating wire 3 for heating inner tube 1 so that heating tube has the higher efficiency of heating surface, the electricity
Heated filament 3 spirals into spring shape.In order to ensure that the heat that heating tube generates is more uniform, the centre of the heating wire 3 of spring shape
Partial screw pitch is larger, and the screw pitch of both ends part is smaller.
