Abstract
The utility model relates to the technical field of casting, and particularly relates to a sand shooting nozzle with a temperature reduction function. The sand shooting nozzle with the temperature reduction function comprises a shooting plate and a tubular sand shooting head, wherein the sand shooting head penetrates through the sand shooting plate, the outer side of the sand shooting head is provided with a fixing seat in the peripheral direction; the fixing seat is fixedly connected with the shooting plate by bolts; a metal pipe is spirally wound along the length direction of the sand shooting head; the metal pipe is internally provided with a cooling liquid channel. According to the utility model, coated sand in the sand shooting nozzle is at normal temperature, and is prevented from being solidified, thereby guaranteeing the quality of mold core products.
Description
Technical field
The utility model casting technology field, is specifically related to a kind of Sha Zui that penetrates 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 operation principle 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 in core box preheating very rapid hardening to certain thickness (being about 5～10 mm) by it taking-up, form smooth surface, accurate in size high-quality core finished product.
Core shooter lower end has the Sha Zui that penetrates that precoated sand is injected to core box, while using hot box to manufacture core, when penetrating Sha Zui and penetrating sand, penetrating sand mouth will stretch in hot box, so penetrating the temperature of sand mouth is easy to raise, the rising of the easy Yin Wendu of precoated sand in penetrating sand mouth and fixed, affects the quality of core, even will penetrate sand mouth and stop up.
Utility model content
The defect existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of Sha Zui that penetrates with cooling function, and this penetrates sand mouth can make to penetrate precoated sand in sand mouth in normal temperature, can guarantee the quality of core product.
For achieving the above object, the technical solution of the utility model is: the Sha Zui that penetrates with cooling function, comprise the sand-shooting head of penetrating plate and tubulose, described sand-shooting head runs through penetrates plate, wherein, described sand-shooting head external circumferential is provided with holder, described holder with penetrate plate and be fixedly bolted, along sand-shooting head length direction spiral winding metal tube, in described metal tube, be provided with cooling passage.
While adopting technique scheme, while using hot box to manufacture core, the sand-shooting head of penetrating sand mouth will stretch in the sandblast hole of hot box, the temperature of hot box is higher, easily transfers heat to sand-shooting head, is spirally wound in the metal tube on sand-shooting head and passes into cooling fluid, by heat, conduct, sand-shooting head temperature is reduced, can be not fixed so can make the interior precoated sand of sand-shooting head in normal temperature, can guarantee the quality of core product.
Further, the nearly sand-shooting head of described metal tube is penetrated one of sand and is brought out cooling fluid, in sand-shooting head, precoated sand temperature from top to bottom raises gradually, so cooling fluid is entered in metal tube close-range shot plate one end, the nearly sand-shooting head of metal tube is penetrated one of sand and brought out cooling fluid and can avoid sand-shooting head epimere to be heated.
Further, described metal tube is copper pipe, and the thermal conductivity factor of copper pipe is very good, so can reach better cooling effect.
Further, described copper pipe oval in shape, the copper pipe of elliptical shape and sand-shooting head contact surface are larger, and heat conduction is fast, so cooling effect is better.
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 of penetrating sand mouth embodiment that the utlity model has cooling function.
The specific embodiment
As shown in Figure 1, a kind of Sha Zui that penetrates with cooling function, comprise the sand-shooting head 2 of penetrating plate 1 and tubulose, sand-shooting head 2 runs through penetrates plate 1, wherein, sand-shooting head 2 external circumferential are provided with holder 21, holder 21 with penetrate that plate 1 is fixing to be fixedly connected with by 3 bolts that are evenly arranged 3, along sand-shooting head 2 length direction spiral winding metal tubes, in metal tube, be provided with cooling passage.
In the present embodiment, metal tube is copper pipe 4, and the thermal conductivity factor of copper pipe 4 is very good, so can reach better cooling effect.The cooling fluid of using is cooling water, the nearly sand-shooting head 2 of copper pipe 4 is penetrated one of sand and is brought out cooling water, in sand-shooting head 2, precoated sand temperature from top to bottom raises gradually, so cooling water is entered in copper pipe 4 close-range shot plate 1 one end, the nearly sand-shooting head 2 of copper pipe 4 is penetrated one of sand and brought out cooling water and can avoid sand-shooting head 2 epimeres to be heated.Copper pipe 4 oval in shape, the copper pipe 4 of elliptical shape is larger with sand-shooting head 2 contact surfaces, and heat conduction is fast, so cooling effect is better.
Specific works flow process:
While using hot box to manufacture core, the sand-shooting head 2 of penetrating sand mouth will stretch in the sandblast hole of hot box, the temperature of hot box is higher, easily transfer heat to sand-shooting head 2, be spirally wound in the metal tube on sand-shooting head 2 and pass into cooling water, by heat, conduct, sand-shooting head 2 temperature are reduced, can be not fixed so can make the interior precoated sand of sand-shooting head 2 in normal temperature.
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.
