Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of hot core box mould of the present utility model;
In figure, 1: die cavity; 2: core; 3: heating rod; 4: heat-insulation layer; 5: fixed head; 6: guide rod; 7: limiting plate; 8: connecting plate; 9: elastic device; 10: push rod; 11: temperature sensor; 12: control device; 13: display unit.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
See Fig. 1, a kind of hot core box mould of the utility model one preferred embodiment, comprise die cavity 1 and core 2, core is arranged on the left surface of die cavity, heating rod 3 is respectively arranged with in core and die cavity, the working face relative with die cavity of core is coated with one deck release coating (not shown), the working face that die cavity is relative with core is also coated with release coating (not shown), core except the side relative with die cavity is respectively arranged with heat-insulation layer 4, die cavity except the side relative with core is also respectively arranged with heat-insulation layer, the lateral surface of heat-insulation layer is fixedly installed fixed head 5, fixed head is fixedly installed on core or die cavity by screw, fixed head is used for fixing heat-insulation layer.
Heat-insulation layer can carry out heat insulation to mold integral, and core and die cavity work when heat-insulation and heat-preservation, can economize energy.Release coating be arranged so that mould operationally need not timing, fixed spraying releasing agent.
As preferably, hot core box mould of the present utility model, the left surface of core is fixedly installed two guide rods 6, the left end of guide rod is fixedly installed limiting plate 7, connecting plate 8 is also provided with between limiting plate and the left surface of core, the two ends of connecting plate are enclosed within guide rod respectively, and be slidably matched between connecting plate and guide rod, elastic device 9 is provided with between connecting plate and limiting plate, the left end of elastic device is fixedly connected with the right flank of limiting plate, the right-hand member of elastic device is fixedly connected on the left surface of connecting plate, the right flank of connecting plate is provided with push rod 10, the left end of push rod is fixedly installed on the right flank of connecting plate, the right-hand member of push rod is each passed through fixed head and heat-insulation layer and stretches in core.
Core and die cavity are when zoarium, push rod is subject to the extruding of die cavity and drives connecting plate to be moved to the left, thus elastic device is squeezed, after shell is made, when core is separated from die cavity, connecting plate slow return drive push rod equably to die cavity force under the action of the elastic means, thus avoid the shell in die cavity damaged.
