Description
Technical field
The utility model relates to a kind of exhaust apparatus, especially relates to a kind of casting sandbox stage casing exhaust apparatus.
Background technology
Watering cast steel casting Sha Moshi, need to vacuumize processing to the sandbox of mould is housed.For small-sized sandbox, can be by the Bas Discharged in sandbox by simply vacuumizing processing.And for large-scale casting sandbox, owing to being subject to the impact of fine sand and the degree of depth thereof, when the exhaust of sandbox stage casing as adopted common vacuum extractor the air in the fine sand in large-scale sandbox stage casing cannot be drained, thereby reduced the vacuum in large-scale sandbox stage casing, be not easy to cast normally the carrying out of operation, also can produce considerable influence to the product quality after casting.
Utility model content
The purpose of this utility model is for existing large-scale sandbox difficult problem that air in the fine sand of large-scale sandbox stage casing is fully discharged when vacuumizing, a kind of casting sandbox stage casing exhaust apparatus of simple in structure, long service life is provided, air in the fine sand of large-scale sandbox stage casing effectively can be discharged, improve the vacuum in large-scale sandbox, and then improve and guaranteed the quality of cast article.
The technical scheme in the invention for solving the technical problem is:
A kind of casting sandbox stage casing exhaust apparatus, mainly comprise support and be wrapped in blast pipe and the motor exhaust on support, it is characterized in that: described support comprises connecting ring, bracing frame, connecting rod and pressure pin, described bracing frame is arranged in connecting ring, bracing frame can improve the intensity of connecting ring, and then also can improve the intensity of bracing frame, the two ends of described connecting rod are all arranged on connecting ring, by iron wire, blast pipe is fixed on connecting rod, many connecting rods can improve the bonding strength of blast pipe and connecting rod, described pressure pin is connected with connecting rod is vertical by welding, simple in structure, easy to assembly, with low cost, pressure pin can prevent that blast pipe from coming off from connecting rod.Because whole device is all to bury in the fine sand in sandbox stage casing except motor exhaust, on described blast pipe, be provided with and connect gap and exhaust outlet, described exhaust outlet is connected with motor exhaust, described connection gap can effectively be discharged air everywhere in fine sand, and discharge sandbox through exhaust outlet and motor exhaust, and then improved the vacuum in sandbox, be conducive to improve the quality of cast article.
Further, described connecting rod, its quantity is 8-15 root.
As preferably, described motor exhaust, is set to servomotor, has high-efficient energy-saving function.
Beneficial effect: the utility model can fully be discharged the air in the fine sand of large-scale sandbox stage casing, improves the vacuum in sandbox stage casing, is convenient to the casting of sandbox inner mold.There is simple structure, dismounting is convenient, cost is low, long service life.Sandbox stage casing good exhaust effect, operating efficiency is high, has guaranteed the quality of cast article.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is top view of the present utility model.
In figure: 1. connecting ring, 2. bracing frame, 3. connecting rod, 4. pressure pin, 5. blast pipe, 6. connect gap, 7. exhaust outlet, 8. motor exhaust.
The specific embodiment
Below with reference to accompanying drawing, the utility model is described in detail.
As shown in attached Fig. 1 and 2: the exhaust apparatus of a kind of casting sandbox stage casing, mainly comprise support and be wrapped in blast pipe 5 and the motor exhaust 8 on support, it is characterized in that: described support comprises connecting ring 1, bracing frame 2, connecting rod 3 and pressure pin 4, described bracing frame 2 is arranged in connecting ring 1, bracing frame 2 can improve the intensity of connecting ring 1, and then also can improve the intensity of bracing frame 2, the two ends of described connecting rod 3 are all arranged on connecting ring 1, its quantity is 12, by iron wire, blast pipe 5 is fixed on connecting rod 3, many connecting rods 3 can improve the bonding strength of blast pipe 5 and connecting rod 3, described pressure pin 4 is connected with connecting rod 3 is vertical by welding, easy to assembly, with low cost, pressure pin 4 can prevent that blast pipe 5 from coming off from connecting rod 3.Because whole device is all to bury in the fine sand in sandbox stage casing except motor exhaust 8, on described blast pipe 5, be provided with and connect gap 6 and exhaust outlet 7, described exhaust outlet 7 is connected with motor exhaust 8, connecting gap 6 can be by absorption of air everywhere in fine sand in blast pipe 5, and discharge sandbox through exhaust outlet 7 and motor exhaust 8, and then improved the vacuum in sandbox, be conducive to improve the quality of cast article.As preferably, described motor exhaust 8, is set to energy-efficient servomotor.The utility model simple structure, easy to implement.
The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
