Abstract
The invention discloses a hot core box sand shooting nozzle, which is installed on a water cooling sand shooting board, and comprises a shooting nozzle core and a shooting nozzle jacket; the shooting nozzle core is a tubular structure, and the center of the shooting nozzle core is provided with a sand shooting hole for precoated sand to pass through; the shooting nozzle jacket externally sleeves the shooting nozzle core, and a water chamber is formed between the shooting nozzle jacket and the shooting nozzle core; the water chamber is communicated with the water cooling sand shooting board, and is used for cooling the precoated sand passing through the sand shooting hole. The hot core box sand shooting nozzle realizes internal cooling function by the water chamber thereof, avoids formation of a useless sand column, saves the cost, and improves the work efficiency.
Description
Technical field
The present invention relates to core mold technical field, particularly a kind of hot box nozzle.
Background technology
Existing hot core box mould, use be the precoated sand being heating and curing, by solidifying before nozzle, must carry out cooling for fear of sand to nozzle.Therefore will be with cooling system when, nozzle designs.At present, generally by penetrating the cooling nozzle of cooling water flow in sand plate.As shown in Figure 1, precoated sand is by 10 ' time of nozzle, and water-cooling sand shooting plate 20 ' interior current carry out cooling to it.In order to reach cooling requirement, traditional nozzle 10 ' press close to as far as possible water-cooling sand shooting plate 20 ', if sand-spraying hole 16 ' long, in nozzle 10 ' bottom, away from water-cooling sand shooting plate 20 ' place, precoated sand will solidify there, cannot pass through mould 30 ' inflow mold cavity 31 ' in.
Another shortcoming of aforesaid way is, nozzle 10 ' in order to press close to water-cooling sand shooting plate 20 ' reduction temperature, can only design shortly as far as possible, but industrial production is to mould 30 ' have requirement of strength, mould 30 ' have certain thickness, so using common nozzle to penetrate the core of sand making can be with one section of auxiliary sand post, after core is made, workman cuts off sand post again, just can obtain final product.
Summary of the invention
The present invention is in order to overcome defect in above-mentioned prior art, cold function in realizing by the water cavity of nozzle self.
For achieving the above object, the invention provides a kind of hot box and penetrate Sha Zui, be arranged on water-cooling sand shooting plate, comprising: nozzle core, it is tubular structure, center is the sand-spraying hole passing through for precoated sand; Nozzle overcoat, it is sleeved on nozzle core outside, forms nozzle water cavity between the two; Nozzle water cavity is connected with water-cooling sand shooting plate, for the cooling precoated sand through sand-spraying hole.
In technique scheme, nozzle core both wings are provided with one section of retaining section, and its width matches with the diameter of nozzle overcoat, and the top of nozzle water cavity is separated in retaining section, form water cavity water inlet and water cavity delivery port, and the bottom of nozzle water cavity is communicated with.
In technique scheme, nozzle water cavity is water hole by water-cooling sand shooting plate and penetrate sand plate water route and be connected.
In technique scheme, nozzle overcoat upper surface is provided with seal groove, and it matches with potted component, for the sealing between nozzle overcoat and water-cooling sand shooting plate.
In technique scheme, nozzle overcoat lower surface is provided with chamfering, for nozzle overcoat and nozzle core welded seal.
In technique scheme, appearance and size and mould that hot box of the present invention is penetrated sand mouth match.
Compared with prior art, the present invention has following beneficial effect: owing to there being nozzle water cavity, nozzle can not penetrated the restriction of sand plate, can be in ensureing that nozzle temperature can be not too high, realize nozzle and press close to mold cavity and penetrate sand, go deep into mould inside and penetrate sand, coordinate common rubber nozzle cover, precoated sand directly can be mapped in mold cavity, penetrate sand after nozzle shift out, can not form useless sand post.Save thus cost, also do not needed the step that operator's later stage prescinds sand post, increased production efficiency.And, there is the mold cavity surface of dark narrow groove at some, tradition nozzle is owing to must design up-small and down-big pattern draft on sand post, cause sand-spraying hole very little, be difficult to meet and penetrate sand area requirement, and nozzle appearance and size of the present invention can match with mould, meet and penetrate sand area requirement.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subject to the restriction of detailed description of the invention.
As shown in Figure 2, a kind of hot box nozzle 10 of the present embodiment, comprises nozzle core 11 and nozzle overcoat 12.Nozzle overcoat 12 is sleeved on outside nozzle core 11, forms nozzle water cavity 15 between the two, and nozzle overcoat 12 lower surfaces and nozzle core 11 are weldingly connected.Nozzle core 11 is tubular structure, and its center is a sand-spraying hole 16.For more clearly demonstrating, Fig. 3 shows the structure after Fig. 2 half-twist.Nozzle core 11 outer wall both wings are provided with one section of retaining section 13, and its width matches with the diameter of nozzle overcoat 12.Because nozzle overcoat 12 and nozzle core 11 only have a place to be weldingly connected, the effect of the relative position that ensures nozzle overcoat 12 tops and nozzle core 11 can be played in retaining section 13.As shown in Figure 4 and Figure 5, nozzle water cavity 15 is separated in retaining section 13, form water cavity water inlet 151 and water cavity delivery port 152, and nozzle water cavity 15 bottoms is still connection, like this cooling water flow by time can take away more heat.Shown in Fig. 6, nozzle overcoat 12 upper surfaces are provided with seal groove 14, and lower surface is provided with the chamfering 18 for welding.Nozzle core 11 welds by chamfering 18 with nozzle overcoat 12, avoids binding site infiltration.
Installation and the working condition of a kind of hot box nozzle of the present embodiment are described below in conjunction with Fig. 7.Nozzle 10 is arranged on water-cooling sand shooting plate 20, in water-cooling sand shooting plate 20, be provided with and penetrate sand plate water route 21, and penetrate sand plate water route 21 and be provided with water hole 22, nozzle water cavity 15 by water hole 22 with penetrate sand plate water route 21 and be connected, coordinate the sealing of heat resistant rubber circle by seal groove 14, avoid nozzle overcoat 12 in the course of work to seep water with the binding site of water-cooling sand shooting plate 20.The length of nozzle 10 can be goed deep into the inside of mould 30, and head cover has rubber nozzle cover 17, direct precoated sand directive mold cavity 31 can be penetrated to sand.After penetrating sand, shift out nozzle, can not form useless sand post.In work, the cooling water flow of penetrating in sand plate water route 21 enters nozzle water cavity 15 by the water cavity water inlet 151 of nozzle 10, the precoated sand in sand-spraying hole 16 is carried out cooling, and the current of heating are flowed back to and penetrated in sand plate water route 21 by water cavity delivery port 152 again.
Disclosed is above only a specific embodiment of the present invention, and still, the present invention is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
