Description
Technical field
The utility model belongs to casting field, relates to a kind of sand box used for casting specifically.
Background technology
In lost foam cast steel process, have corresponding requirement, only in this way just can make metallographic structure, grain size, can reach requirement each stage cooling velocity in Fe-Fe3C phasor, the quality of foundry goods is just secure.Due to the impact by many factors such as environment, in lost foam cast steel process, existing sandbox does not often reach above-mentioned requirements, affects casting quality.
Summary of the invention
The utility model, for above-mentioned technical problem, provides a kind of sand box used for casting, and this sandbox has the function controlled cooling velocity, thus ensures the quality of foundry goods.
Concrete technical scheme of the present utility model is: a kind of sand box used for casting, comprise sandbox housing and case lid, described case lid is provided with the clamp system clamping described sandbox housing, the inwall of described sandbox housing has heating inner liner, also comprise temperature control equipment, described temperature control equipment comprises sets of temperature sensors, signal processing unit and control unit, sets of temperature sensors comprises several temperature sensor, and several temperature sensor is all connected with signal processing unit, signal processing unit is connected with control unit respectively, control unit and described heating inner liner control connection.
Described heating inner liner is face calandria; Described calandria is be arranged on five heating resistor plates on sandbox inner walls four sides and bottom surface, and each described heating resistor plate is connected with described control unit respectively.
Described temperature sensor is arranged on described heating resistor plate.
Described sandbox housing is provided with control interface, and described control unit is connected with heating resistor plate by described control interface.
The outer symmetrical of described sandbox housing is provided with two folder ears, these two folder ears are corresponding with two clamp systems that described case lid is provided with, each described clamp system comprises connector, snap fit and bearing pin, and described connector is fixed on case lid, and snap fit is rotationally connected by bearing pin and connector.
At least one deck insulation material is also provided with between described sandbox housing and heating inner liner.
When using above-mentioned sandbox, the cooling velocity in lost foam cast steel each stage can be set by temperature control equipment, so just can make in lost foam cast steel process, each stage cooling velocity in Fe-Fe3C phasor is controlled, thus not by the impact of the factors such as environment, make metallographic structure, grain size, all reach requirement, thus ensure casting quality.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, a kind of sandbox of the utility model, a kind of sandbox, comprises sandbox housing 1 and case lid 6.Described case lid 6 is provided with the clamp system clamping described sandbox housing.The inwall of described sandbox housing 1 has heating inner liner, also comprises temperature control equipment, and described temperature control equipment comprises sets of temperature sensors 3, signal processing unit and control unit.Sets of temperature sensors 3 comprises several temperature sensor, and several temperature sensor is all connected with signal processing unit, and signal processing unit is connected with control unit respectively, control unit and described heating inner liner control connection.Described temperature control equipment comprises sets of temperature sensors 3, signal processing unit and control unit, is prior art, therefore does not describe in detail here.Further, described heating inner liner is face calandria; Described calandria is be arranged on five heating resistor plates 2 on sandbox inner walls four sides and bottom surface, and each described heating resistor plate 2 is connected with described control unit respectively.Further, described sandbox housing 1 is provided with control interface 4, and described control unit is connected with heating resistor plate by described control interface 4.Described temperature sensor 3 is arranged on described heating resistor plate 2.Further, the outer symmetrical of described sandbox housing 1 is provided with two folder ears, these two folder ears are corresponding with two clamp systems that described case lid is provided with, each described clamp system comprises connector 71, snap fit 73 and bearing pin 72, described connector 71 is fixed on case lid 6, and snap fit 73 is rotationally connected by bearing pin 72 and connector 71.At least one deck insulation material 5 is also provided with between described sandbox housing 1 and heating inner liner.When using above-mentioned sandbox, according to the difference of cast steel kind, the cooling velocity in lost foam cast steel each stage can be set by temperature control equipment, so just can to evaporative pattern in cast steel process, each point and each stage cooling velocity in Fe-Fe3C phasor are controlled, makes metallographic structure, grain size, all reach requirement, thus ensure casting quality.
