Abstract
The utility model relates to a core shooter, and in particular relates to a core shooter with a cooling function. The core shooter comprises a sand hopper, a sand shooting tube, a sand shooting hopper, a sand shooting plate and a sand shooting nozzle, wherein a water cooling jacket is arranged outside the sand shooting plate, and a cooling layer is formed between the water cooling jacket and the sand shooting plate; a water inlet pipe is arranged at the lower end of one side of the water cooling jacket, while a water outlet pipe is arranged at the upper end of the opposite side of the water cooling jacket. Precoated sands in the sand shooting hopper can be kept at normal temperature because the bottom of the sand shooting hopper of the core shooter is subjected to twice cooling processes, cooling water flows by a long path, and the cooling efficiency is high.
Description
Technical field
The utility model relates to a kind of core shooter, is specifically related to a kind of core shooter with cooling function.
Background technology
Core shooter is to adopt precoated sand coremaking, is applicable to two kinds of hot box and cold-boxs, and core shooter is widely used in casting industry, and the core size of manufacturing with core shooter is accurate, any surface finish.Core shooter comprises sand hopper, blasting unit, penetrates sand hopper, penetrates sand plate and penetrate Sha Zui, the operation principle of core shooter is to inject in the core box after heating take the core sand compound that liquid state or solid state heat thermosetting resin be binding agent, core is very rapid hardening of heat in core box, when solidifying, acquire a certain degree (cured layer thickness is greater than 2mm completely) by it taking-up, form smooth surface, accurate in size high-quality core finished product.
While using hot box to manufacture core, the temperature of hot box is at 140 ℃～300 ℃, during coremaking, core shooter is positioned at the top of hot box, so penetrating sand hopper bottom is easy to heat up, conventionally it is insensitive that hot box coated sand has the precoated sand performance impact that heat radiation that higher fusing point correlation sand hopper bottom is subject to and heat conduction bring, and therefore common core shooting mechanism can meet use completely.But for the lower precoated sand of fusing point and water-based inorganic binding agent is prepared from hygrometric state sand, the serviceability that causes comparatively significantly sand because penetrating heat radiation that sand hopper bottom is subject to or hot conduction meeting, cause coremaking penetrate sand mouth stop up, penetrate sand unreal, penetrate discontented etc. the problems of sand, the core shooting mechanism of existing use is provided with cooling-water duct in penetrating sand plate, this sand plate of penetrating can suitably be lowered the temperature for penetrating sand hopper, but can not effectively play the effect of heat insulation and heat control not because of heat exchanger effectiveness.
Utility model content
The defect existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of core shooter with cooling function, this core shooter penetrate sand hopper bottom through twice cooling, can guarantee to penetrate precoated sand in sand hopper in normal temperature, and cooling water flow pathway line length, cooling effectiveness is high.
For achieving the above object, the technical solution of the utility model is: the core shooter with cooling function, comprise from top to bottom the sand hopper, the blasting unit that connect successively, penetrate sand hopper, penetrate sand plate and penetrate Sha Zui, wherein, the described sand plate of penetrating is provided with water-cooling jacket outward, this water-cooling jacket and penetrate between sand plate and form cooling layer, the lower end of described water-cooling jacket one side is provided with water inlet pipe, and the upper end of a relative side is provided with outlet pipe.
While adopting technique scheme, water-cooling jacket and penetrate and form upper and lower two-layer cooling layer between sand plate, cooling water enters from the water inlet pipe of water-cooling jacket one side, from the outlet pipe of a relative side, flow out, cooling water is full of whole cooling layer, and cooling water flow warp is longest in route, can absorb fully the heat that hot box transmits, cooling effectiveness is high.
Further, the thickness of each position of described cooling layer is identical, so just can make to penetrate the synchronously cooling everywhere of sand hopper bottom, guarantees that the precoated sand quality of penetrating in sand hopper is even.
Further, described water-cooling jacket is provided with temperature sensor, and water inlet pipe is provided with flow control valve, by temperature sensor, detects in real time the water temperature in cooling layer, then the flow of cooling water is regulated, thereby controls the temperature of penetrating sand hopper bottom.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation that the utlity model has the core shooter embodiment of cooling function;
Fig. 2 is the structural representation that the core shooter embodiment that the utlity model has cooling function penetrates sand plate portion.
The specific embodiment
As shown in Figure 1, a kind of core shooter with cooling function, comprise the sand hopper 11 connecting successively from top to bottom, blasting unit 10, penetrate sand hopper 9, penetrate sand plate 1 and penetrate sand mouth 8, wherein, penetrate the outer water-cooling jacket 2 that is provided with of sand plate 1, this water-cooling jacket 2 and penetrate and form cooling layer 21 between sand plate 1, the lower end of water-cooling jacket 2 one sides is provided with water inlet pipe 3, the upper end of a relative side is provided with outlet pipe 7, the inwall of water-cooling jacket 2 downsides is provided with deflector, the water inlet direction of deflector vertical inlet pipe 3, deflector is along the both sides interlaced arrangement of water-cooling jacket 2, form tortuous flow of cooling water water route.
In the present embodiment, the thickness of cooling layer 21 each positions is identical, so just can make to penetrate the synchronously cooling everywhere of sand hopper 9 bottoms, guarantees that the precoated sand quality of penetrating in sand hopper 9 is even.
Water-cooling jacket 2 is provided with temperature sensor 6, water inlet pipe 3 is provided with flow control valve 4, also be provided with in addition the controller 5 being electrically connected to temperature sensor 6 and flow control valve 4, by temperature sensor 6, detect in real time the water temperature in cooling layer 21, controller 5 reduced temperature values, then the flow of cooling water is regulated, thereby control the temperature of penetrating sand hopper 9 bottoms.
Specific works flow process:
As shown in Figure 1, while using core shooter manufacturing mold core, core shooter integral body is positioned at the top of hot box, cooling water enters from the water inlet pipe 3 of water-cooling jacket 2 one sides, from the outlet pipe 7 of a relative side, flow out, cooling water is full of whole cooling layer 21, penetrate sand plate 1, water-cooling jacket 2 and cooling layer 21 will be penetrated sand hopper 9 and separate with hot box, in coremaking process, core shooter can move up and down, so the temperature of penetrating in sand hopper 9 can change, the temperature of water in the cooling water layer of temperature sensor 6 Real-Time Monitoring, by controller 5 reduced temperature values, thereby the cooling water flow of adjusting in water inlet pipe 3 by flow control valve 4, the temperature constant in sand hopper 9 is penetrated in assurance, the precoated sand quality of penetrating in sand hopper 9 is even, guarantee core product quality.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
