In embodiments of the present invention, the constant volume of accommodating cavity 13, while being filled between piston 3 and elastic sealing element 4
Driving matter with certain viscosity and mobility, this guarantees no matter piston 3 and elastic sealing element 4 are any contour structures,
No matter elasticity how, which occurs, for the shape of elastic sealing element 3 changes, the position that piston 3 moves in accommodating cavity 13 to resin cavity direction
The dosage centainly flowed out from resin cavity with resin 5 is moved in one-to-one relationship.As long as presetting and monitoring piston 3 in piston
Displacement distance in chamber, it will be able to obtain corresponding resin infusion dosage.It is computed in advance according to actual size when specifically used
The correspondence of piston 3 displacement distance and resin infusion dosage sets straight line power drill/driver 2 (i.e. piston 3) by controller
Preset displacement, and control the mobile preset displacement of straight line power drill/driver 2 (i.e. piston 3), also can be obtained by accurate tree
Dosage is perfused in fat, i.e., ensure that sand core quality in terms of resin infusion dosage.
Specifically, displacement sensor 10 is displacement encoder.
Optionally, the scheme of resin infusion dosage is accurately controlled as another kind, resin provided in an embodiment of the present invention fills
Dispensing device further includes controller, and straight line power drill/driver 2 is servoBcylinder, and servoBcylinder is electrically connected with the controller.ServoBcylinder is a kind of
Stroke (displacement) can be accurately controlled by controller and the linear reciprocation actuator of stroke (displacement) information is fed back to controller,
More accurate resin infusion dosage can be provided as straight line power drill/driver 2.In embodiments of the present invention, accommodating cavity 13
Constant volume, while the driving matter with certain viscosity and mobility is filled between piston 3 and elastic sealing element 4, this is just protected
Demonstrate,prove no matter what contour structures piston 3 and elastic sealing element 4 are, no matter elasticity how occurs for the shape of elastic sealing element 3
Change, the dosage that the displacement that piston 3 moves in accommodating cavity 13 to resin cavity direction is centainly flowed out with resin 5 from resin cavity is in one
One correspondence.As long as presetting and monitoring displacement distance of the piston 3 in plunger shaft, it will be able to obtain corresponding resin
Dosage is perfused.When specifically used, closed according to actual size 3 displacement distance of piston computed in advance and the corresponding of resin infusion dosage
System, the preset displacement of servoBcylinder (i.e. piston 3) is set by controller, and controls the mobile preset position of servoBcylinder (i.e. piston 3)
It moves, also can be obtained by accurate resin infusion dosage, i.e., ensure that sand core quality in terms of resin infusion dosage.
