In one of the present utility model, provide a kind of device for heating low-pressure casting die of aluminum vehicle wheel, described device is made up of natural gas and compressed-air actuated import (1), UNICOM's conduit (2), support (3), upper heating tube (4) and lower heating tube (5), it is characterized in that: natural gas and compressed-air actuated import (1) are the import of bifurcated and are connected respectively to gas source and compressed air source; One end of UNICOM's conduit (2) and natural gas and compressed-air actuated import (1) are in fluid communication, and the other end and upper heating tube (4) and lower heating tube (5) are in fluid communication; Support (3) is fixed to UNICOM's conduit (2); Upper heating tube (4) and lower heating tube (5) are circular arc, and on comprise bottoming hole.
In the utility model is preferred, upper heating tube (4) and lower heating tube (5) comprise the multiple bottoming hole under being tilted to and/or deviate from the multiple bottoming holes surface of side, the center of circle comprising horizontal direction in circular arc on the surface of circular arc to side, the center of circle.
In the utility model is preferred, the diameter of described bottoming hole is 2-3mm.
In the utility model is preferred, the diameter of described bottoming hole is 2.5mm.
In the utility model is preferred, the spacing of described bottoming hole is 15-50mm.
In the utility model is preferred, the spacing of described bottoming hole is 30mm.
In the utility model is preferred, described support (3) is for two-piece type support and connected by bolt between its two pieces.
In the utility model is preferred, described UNICOM's conduit (2) is provided with fireproof tempering device.
Also describe in description of the present utility model and use previously described device to heat the method for low-pressure casting die of aluminum vehicle wheel, it is characterized in that, described method comprises step: the device according to any one of two pieces claim 1-8 is installed to low-pressure casting die of aluminum vehicle wheel by (A), and makes heating tube (4) and lower heating tube (5) lay respectively between the wheel rim part of the limit mould of low-pressure casting die of aluminum vehicle wheel and the contoured section of the low mould of backform; (B) import to the bifurcated of natural gas and compressed-air actuated import (1) inputs natural gas and compressed air respectively, and lights a fire at heating gate place; And after (C) igniting, mould is used the device heating 40-80 minute according to any one of claim 1-8.
In the utility model is preferred, the described heat time is 60 minutes.
The device that the utility model provides can significantly promote the mould efficiency of heating surface, reduces energy consumption, effectively avoids thermocouple, snap joint and sealing ring to be destroyed in high temperature environments, to ensure that it normally uses.
Accompanying drawing explanation
Below, describe embodiment of the present utility model in detail by reference to the accompanying drawings, wherein:
Fig. 1 is the front view of device of the present utility model;
Fig. 2 is the left view of device of the present utility model; And
Fig. 3 is the using state figure of device of the present utility model;
1. natural gases and compressed-air actuated import in figure, 2. UNICOM's conduit, 3. support, 4. go up heating tube, 5. descends heating tube, 6. mold side mould, 7. mold bottom die, 8. mold top holder.
Detailed description of the invention
embodiment 1
In Fig. 1 front view, natural gas and compressed air enter heater by import 1, and import 1 is connected with snap joint, and by Valve controlling natural gas and compressed air require.2 make split two parts as the support of heater in actual fabrication process, connect with bolt, and object is to coordinate the mould of differing heights to use.3 is upper heating tubes of heater, and this heating tube is processed the hole of circle inner side Ф 2.5 obliquely, and span is 30mm.The wheel rim part of the flame heating backform come out by bottoming hole.4 is lower heating tubes of heater, this heating tube is processed a circle inner side, and the hole of the Ф 2.5 blown is put down in the hole of Ф 2.5 and outside obliquely, span is 30mm, the flame heating top come out by inner side bottoming hole, the front pose position of bed die, the wheel rim part of the flame heating edge mould come out by outside bottoming hole.
Fig. 2 is the principle of heating figure of heater, is adjusted color and the size of flame by the external valve controlling import 1 place, and blue flame is best, can ensure the efficient rate of heat addition, can ensure again the outward appearance not blackening of mould.1h is needed through the supreme machine of this heating devices heat mould of verification experimental verification temperature required (350 ~ 400 DEG C), and by we the current temperature required at least 3.5h of the supreme machine of heating furnace heating mould, undertaken heating not only substantially increasing the efficiency of heating surface by this heater, what is more important has been saved mass energy consumption and has been reduced production cost.
Can be found out by the principle of heating figure of Fig. 2, this heater heating mould die cavity, after heating terminates, mold outer surface temperature is relatively low, and this not only improves external environment when workman installs, and greatly reduces the possibility of scald.It also avoid the thermocouple and seal washer inefficacy and the normal production of impact that cause because of high temperature simultaneously.
Mold heating device of the present utility model, is not limited to content described in the utility model, and every other corrective measures obtained according to the inspiration of the utility model content, all fall into protection domain of the present utility model.
