Accompanying drawing explanation
Below, describe embodiment of the present invention in detail by reference to the accompanying drawings, wherein:
Fig. 1 is the front view of device of the present invention;
Fig. 2 is the left view of device of the present invention; And
Fig. 3 is the using state figure of device of the present invention;
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 invention, is not limited to content of the present invention, and every other corrective measures obtained according to content inspiration of the present invention, all fall into protection scope of the present invention.
