Abstract

The utility model provides a technical proposal of lost foam casting drench sand adding machine, and the lost foam casting drench sand adding machine comprises a sand adding box. The technical proposal is characterized in that the bottom of the sand adding box is provided with a first sand leaking plate which is provided with a sand leaking hole; a second sand leaking plate is arranged under the first sand leaking plate, and a sand leaking hole of the second sand leaking plate is staggered with the sand leaking hole of the first sand leaking plate; a lever is arranged at the outer side of the sand adding box and provided with a cross rod, one side of which is fixed with a handle and the other side thereof is fixed with two connecting rods; the cross rod is connected with the sand adding box, and the two connecting rods of the lever are respectively connected with the second sand leaking plate by two fixed links. The drench sand adding machine can control sand adding in time, weaken the impact force of the sand, and avoid the sand from affecting a model.

Description

A kind of lost foam casting drenches with rain and adds the sand device

Technical field:

The utility model relates to a kind of sanding device, especially a kind of dispellable mould casting drenches with rain and adds the sand device.

Background technology:

In the prior art, when technique known is lost foam casting, be directly in the casting sandbox, to add sand, there are not control corresponding device and sanding device, sand directly enters and impacts the very big bubbles model distortion that makes easily in the sandbox, influence the quality of foundry goods, this is the existing in prior technology weak point.

Summary of the invention:

The purpose of this utility model, be exactly at the existing in prior technology deficiency, and provide a kind of dispellable mould casting to drench with rain to add the technical scheme of sand device, the drenching with rain of this scheme adds the sand device and can control timely and add sand, and can weaken the impulsive force of sand, avoid the influence of sand model.

This programme is realized by following technical measures: a kind of lost foam casting drenches with rain and adds the sand device, comprise and add sandbox, the characteristics of this programme are: be provided with the first leakage sand plate that has the leakage sand hole in the bottom that adds sandbox, below the first leakage sand plate, also be provided with second and leak the sand plate, the second leakage sand hole and the first leakage sand hole that leaks the sand plate that leaks the sand plate staggers mutually, in the described outside that adds sandbox a lever is arranged, described lever has a cross bar, one side of cross bar is fixed with handle, opposite side is fixed with two connecting rods, described cross bar with add sandbox and be connected, two connecting rods of lever are connected with the second leakage sand plate by two fixed bars respectively.Cross bar by two hinges with add sandbox and be connected.Connecting rod is to be connected by bolt with fixed bar.Connecting rod and second leaks the sand plate and is connected by bolt.

The beneficial effect of this programme can be learnt according to the narration to such scheme, because also have second to add the sand plate below the first leakage sand plate in this scheme, second adds the sand plate also is connected with a lever by connecting rod, when not working, the two-layer leakage sand hole that adds the sand plate staggers, can add in the past and fill it up with sand in the sandbox, the sand that can not leak down is in the time of need adding sand in the casting sandbox, the lever of leaving behind, second adds the sand plate moves under the effect of lever, makes the two-layer leakage sand hole that adds the sand plate communicate, and begins to leak sand.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.

Description of drawings:

Fig. 1 adds sand device front view for lost foam casting drenches with rain.

Fig. 2 adds sand device left view for lost foam casting drenches with rain.

Fig. 3 adds sand device vertical view for lost foam casting drenches with rain.

Among the figure, 1 is handle, and 2 for adding sandbox, and 3 is hinge, and 4 is connecting rod, and 5 is bolt, and 6 is fixed bar, and 7 is the second leakage sand plate, and 8 is the first leakage sand plate, and 9 is cross bar, and 10 for leaking sand hole.

The specific embodiment:

For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.

By accompanying drawing as can be seen, the lost foam casting of this programme drenches with rain and adds the sand device, comprise and add sandbox 2, the characteristics of this programme are: be provided with the first leakage sand plate 8 that has leakage sand hole 10 in the bottom that adds sandbox 2, below the first leakage sand plate 8, also be provided with second and leak sand plate 7, the second leakage sand hole and the first leakage sand hole 10 that leaks sand plate 8 that leaks sand plate 7 staggers mutually, in the described outside that adds sandbox 2 lever is arranged, described lever has a cross bar 9, one side of cross bar 9 is fixed with handle 1, opposite side is fixed with two connecting rods 4, described cross bar 9 with add sandbox 2 and be connected, two connecting rods 4 of lever are connected with the second leakage sand plate 7 by two fixed bars 6 respectively.Cross bar 9 by two hinges 3 with add sandbox 2 and be connected.Connecting rod 4 is to be connected by bolt 5 with fixed bar 6.Connecting rod 4 and second leaks sand plate 7 and is connected by bolt 5.
