Abstract

The utility model provides a sand adding device of a core shooting machine. The sand adding device can stably and effectively discharge sand, has a good sand discharging effect and is difficult to damage. The sand adding device comprises a sand bucket arranged on a stander, and is characterized in that a sand adding opening is formed below a sand outlet of the sand bucket; a gate plate is correspondingly arranged at the sand adding opening; the lower end of the sand adding opening is connected with a sand discharging channel; a valve device is arranged at the tail end of the sand discharging channel.

Description

The sanding device of core shooter

Technical field

The utility model relates to sand molding production technical field, is specially the sanding device of core shooter.

Background technology

In recent years, core shooter is to save core cost, core aeration is good, the advantages such as low gas forming amount cast(ing) surface is bright and clean, and precision is high, good mechanical property, be widely used in casting industry, use core shooter not only can save auxiliary equipment and instrument for a lot of coremaking, can also reduce labor intensity, for mechanization, the automation of coremaking process creates conditions, application prospect is good.

In the process that use core shooter is produced, need to penetrate sand to blasting unit, penetrate before sand and need correlation bucket to add molding sand, can be under the sand export place of sand storage bin directly connects in existing equipment sand passage, and below lower sand passage, valve being set, the switch by valve completes and adds sand step.Yet so often can be because a large amount of sands in sand storage bin are directly stacked on valve while being arranged on actual use; valve pressurized excessive deformation; the sealing that can affect valve can impact valve run switch simultaneously, and it is undesirable that sanding device is put sand effect simultaneously.

Utility model content

For the problems referred to above, the utility model provides the sanding device of core shooter, and it can be stablized and effectively puts sand, puts sand effective, not fragile.

Its technical scheme is such: it comprises rack-mounted sand hopper, it is characterized in that: the sand export below of sand hopper is provided with and adds sand mouth, described in correspondence, add Sha Kouchu and be provided with flashboard, described in add sand mouth lower end be connected with lower sand passage, the end of described lower sand passage is provided with valving.

It is further characterized in that: described valving comprises valve, on described valve, offers clearance hole;

Described valve is connected with lower plate by screw, and described lower plate is connected with the guide rod that is pressed with spring, and one end of described guide rod is fixed on the support of frame one side;

The described sand mouth that adds comprises suitable for reading and end opening, described sand export extend into described suitable for reading in;

Described sand hopper is arranged in described frame by cushion block;

On the outer wall of the end of lower sand passage, by pressing plate and holddown spring, be pressed with sealing ring.

Adopt after design of the present utility model, the sand when flashboard arranging between the sand export of sand hopper and valve makes not put sand in sand hopper can directly not touch valve, valve is produced to pressure, can not cause valve distortion, damage valve, after long-term use, only need to change flashboard, reduced maintenance cost; The molding sand that is arranged so that of flashboard more easily falls simultaneously, puts sand effective.

Accompanying drawing explanation

Fig. 1 is that master of the present utility model looks schematic diagram;

Fig. 2 is schematic side view of the present utility model.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described further.

See Fig. 1, Fig. 2, the utility model comprises by cushion block 1 and is arranged on the sand hopper 3 in frame 2, sand export 4 belows of sand hopper 3 are provided with and add sand mouth 5, correspondence adds sand mouth 5 places and is provided with flashboard 6, the lower end that adds sand mouth 5 is connected with lower sand passage 7, the end of lower sand passage 7 is provided with valving, described valving comprises valve 8, on valve 8, offer clearance hole 9, valve 8 is connected with lower plate 11 by screw 10, lower plate 11 is connected with the guide rod 13 that is pressed with spring 12, one end of guide rod 13 is fixed on the support 14 of frame 1 one sides, on the outer wall of the end of lower sand passage 7, by pressing plate 15 and holddown spring 16, be pressed with sealing ring 17, add sand mouth 5 and comprise suitable for reading 18 and end opening 19, sand export 4 extends in suitable for reading 18.

When sand hopper carries out sand control, first removing flashboard 6 promotes valve 8 again and makes clearance hole 9 carry out sand control over against lower sand passage 7, putting that sand finishes is that first mobile valve 8 is installed flashboard 6 again, the sand when flashboard 6 arranging between the sand export 4 of sand hopper and valve 8 makes not put sand in sand hopper 3 can directly not touch on valve 8, valve 8 is produced to pressure and make valve 8 distortion, damage valve 8, after long-term use, only need to change flashboard 6, reduced maintenance cost; The molding sand that is arranged so that simultaneously adds sand mouth 5 more easily falls, and puts sand effective.

Claims
