In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
the invention provides a sand leakage prevention sand shooting nozzle for a large-caliber core shooting mould, which comprises: the sand shooting nozzle comprises a sand shooting nozzle body, a rubber nozzle head and a cross rib, and is characterized in that bosses are arranged on two sides of the lower end of the sand shooting nozzle body, grooves matched with the bosses are arranged at the upper end of the rubber nozzle head and used for connecting the sand shooting nozzle body with the rubber nozzle head, and an inner groove is arranged on the inner wall of the lower end of the rubber nozzle head and used for embedding the cross rib into the inner groove; the cross muscle includes two mutually perpendicular's cross muscle bodies, every the cross muscle body includes: the chute section comprises arc sections and chute sections, wherein the arc sections are arranged at two ends of the chute section respectively and embedded into the inner groove, and a chute is arranged at the top of the chute section and used for enabling sand to fall into the chute and automatically stacking the sand by means of gravity, so that the sand is prevented from further falling.
Further, the chute is a groove arranged along the centerline of the chute section.
Furthermore, the cross ribs are made of rubber and are used for being extruded and embedded into the inner grooves.
The invention has the beneficial effects that: the invention is not limited by the diameter of the sand shooting nozzle, the area of the sand shooting nozzle is divided into four by adding a rubber cross rib at the head of the sand shooting nozzle, and meanwhile, the top of the cross rib is provided with a chute, so that sand falls into the chute and is automatically accumulated by gravity, and the sand does not fall off under the condition of no external force, thereby not only effectively solving the problem of sand leakage of the large-diameter core shooting die nozzle, but also not influencing the sand shooting during sand shooting; meanwhile, the sand shooting nozzle head is made of rubber, the rubber nozzle head and the rubber cross ribs are combined to form the sand shooting nozzle head structure, and the sand shooting nozzle head structure made of the rubber enables the adhesion friction force of sand to be far higher than that of rigid materials, so that the sand shooting nozzle head structure is more beneficial to natural accumulation of the sand, and is simple to manufacture and low in cost.

Detailed Description
In order that those skilled in the art can better understand the technical solutions of the present invention, the present invention will be further described in detail with reference to specific embodiments. The following examples are illustrative only and are not to be construed as limiting the invention.
Fig. 1 is a sectional view of a structure of a sand shooting nozzle in the prior art, fig. 2 is a schematic structural view of a head of the sand shooting nozzle in the prior art, and referring to fig. 1 and fig. 2, when a sand shooting mechanism ascends and before sand shooting is prepared, sand is very easy to fall off from the sand shooting nozzle due to a large caliber of the sand shooting nozzle, once the sand 4 falls off, a sand core formed by sand shooting cannot meet the requirement, and the quality is seriously affected.
The invention provides a sand leakage prevention sand shooting nozzle for a large-caliber core shooting mould, and figure 3 is a structural sectional view of the sand shooting nozzle, which is shown in figure 3 and comprises the following components: the sand shooting nozzle comprises a sand shooting nozzle body 1, a rubber nozzle head 2 and a cross rib 3, wherein bosses 101 are arranged on two sides of the lower end of the sand shooting nozzle body, grooves 201 matched with the bosses are formed in the upper end of the rubber nozzle head and used for connecting the sand shooting nozzle body with the rubber nozzle head, and an inner groove 202 is formed in the inner wall of the lower end of the rubber nozzle head and used for embedding the cross rib into the inner groove.
According to the embodiment of the invention, the cross-shaped rib is made of rubber and is used for being extruded and embedded into the inner groove, meanwhile, because the traditional sand shooting nozzle head is made of rigid material, the sand shooting nozzle head is changed into the rubber material, the rubber nozzle head and the rubber cross-shaped rib are combined into a sand shooting nozzle head structure, and meanwhile, the sand adhesion friction force of the sand shooting nozzle head structure made of the rubber material is far higher than that of the rigid material, so that the sand is more beneficial to natural accumulation, and meanwhile, the manufacturing is simple and the cost is low.
