Abstract
The utility model relates to a shooting barrel which comprises a barrel body. A sand feeding port is arranged on the upper portion of the barrel body, a shooting head is arranged on the lower portion of the barrel body, a cover body is arranged on the upper portion of the barrel body, a closed cavity capable of storing resin sand is formed in the barrel body through the cover body, and a humidifying device is connected in the closed cavity. The cover body is added on the prior shooting barrel, ensures that some resin sand sensitive to humidity, particularly inorganic resin sand can ensure required humidity requirements in the core manufacture process, is not affected by external factors such as environment, time and the like, meets requirements for the core manufacture process, and can finish core manufacture in the optimum state.
Description
Technical field
the utility model relates to a kind of coremaking servicing unit, particularly relates to a kind of tube of penetrating.
Background technology
It is the chief component of core making machine that tube is penetrated in
, and its effect is the resin sand when depositing each coremaking.As shown in Figure 1, to penetrate tube and comprise that cylindrical shell 1 ', cylindrical shell 1 ' top offer and add sand mouth 10 ', cylindrical shell 1 ' bottom is connected with penetrates 2 ', penetrates 2 ' and is provided with and penetrates plate 20 ', penetrates and is connected with several nozzles 21 ' on the plate 20 '.When coremaking equipment need be penetrated sand, resin sand 8 ' from cylindrical shell 1 ' through penetrating 2 ' and nozzle 21 ' inject core box 9 ', move on to then and add the sand station and add and penetrate the resin sand 8 ' that sand is used next time, and wait for the sand of penetrating next time.Present situation be when add penetrate the resin sand 8 ' that sand uses next time after; The sand mouth 10 ' that adds of whole cylindrical shell 1 ' opens wide; Just contact with air; And need a period of time just can penetrate sand,, thereby influence the coremaking effect with contacting than dry air to take away the moisture of resin sand 8 ' so for a long time if the resin sand of depositing this moment 8 ' (like inorganic resin sand) needs good humidity could guarantee its coremaking effect.Like this, the tube of penetrating that opens wide adds the sand mouth and can make certain resin sand to humidity sensitive in the tube lose moisture, influences implementation effect.
Summary of the invention
The purpose of
the utility model provides a kind of tube of penetrating.
For achieving the above object, the technical scheme that the utility model adopts is:
a kind of tube of penetrating; Comprise cylindrical shell; Described cylindrical shell top offers and adds the sand mouth, and described cylindrical shell bottom is connected with penetrates head, and described cylindrical shell top is provided with lid; Described barrel forms the closed cavity that can store resin sand through described lid, and is connected with damping device in the described closed cavity.
preferably, described cylindrical shell top is provided with fixed mount, described lid is installed on the described fixed mount.
further preferably, described fixed mount is provided with pipeline, and described damping device is connected with closed cavity through described pipeline.
further preferably are provided with sealing ring between described fixed mount and the described cylindrical shell.
preferably, described lid is automatic telescoping cover.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
the utility model is through increasing a lid on original top of penetrating; Guarantee some to the resin sand of humidity sensitive particularly inorganic resin sand can in the coremaking process, guarantee its required humidity requirement; Do not receive the influence of extraneous factors such as environment, time; Satisfy the core manufacturing craft requirement, make it accomplish coremaking with optimal state.
Description of drawings
Accompanying drawing 1 is the structural representation of penetrating tube of prior art;
accompanying drawing 2 is the structural representation of penetrating tube of the utility model.
wherein: 1, cylindrical shell; 10, add the sand mouth; 11, closed cavity; 2, penetrate head; 20, penetrate plate; 21, nozzle; 3, lid; 4, damping device; 5, fixed mount; 6, pipeline; 7, sealing ring; 8, resin sand.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
A kind of tube of penetrating that
are as shown in Figure 2 comprises cylindrical shell 1, and cylindrical shell 1 top offers and adds sand mouth 10, and cylindrical shell 1 bottom is connected with penetrates 2, penetrates 2 and is provided with and penetrates plate 20, penetrates and is connected with several nozzles 21 on the plate 20.Cylindrical shell 1 top is provided with lid 3, and cylindrical shell 1 inside forms the closed cavity 11 that can store resin sand 8 through lid 3, and is connected with damping device 4 in the closed cavity 11.
in the present embodiment, cylindrical shell 1 top is provided with fixed mount 5, lid 3 is installed on the fixed mount 5, and lid 3 is automatic telescoping cover; Fixed mount 5 is provided with pipeline 6, and damping device 4 is connected with closed cavity 11 through pipeline 6.
are provided with sealing ring 7 between fixed mount 5 and the cylindrical shell 1 in addition.
are when penetrating tube when adding sand; Automatically telescoping cover is opened; Make to have added resin sand 8 smoothly in the cylindrical shell 1, add behind the sand automatically that telescoping cover closes up, make that closed cavity 11 and the external air of cylindrical shell 1 is isolated and be in an airtight relatively environment and keep original resin sand humidity; As penetrate tube and will wait in the time of just need penetrating sand for a long time, also can in cylindrical shell 1, add an amount of moisture and guarantee its interior humidity through damping device 4.Like this, no matter which kind of length of following time of situation can not influence the original humidity of resin sand, also just guaranteed the coremaking effect in.
the foregoing description is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the utility model.
