Description

Technical Field

[0001] The invention relates to the technical field of cooling cast products, and in particular to a cooling water spraying device for cast products. Background Art

[0002] In the investment casting process, shrinkage cavity is one of the most common defects of investment castings. Shrinkage cavity can be prevented by simultaneous solidification method and sequential solidification method. When controlling the sequential solidification method, it should be ensured that the casting forms a certain positive temperature gradient distribution in the direction of the shrinkage component during the solidification process. The cooling rate at the starting point of solidification should be larger. At the same time, isolated hot nodes should be avoided when controlling the solidification method. For isolated hot nodes where it is difficult to set up inner gates and risers, efforts should be made to increase the solidification cooling rate there. In sand casting, isolated hot nodes can be equipped with internal and external chillers to increase their solidification cooling rate. However, for investment casting, since the mold shell has been roasted at high temperature and The mold shell is poured at high temperature, and the cold iron is very easy to oxidize during the roasting process, and the heat absorption efficiency of the high-temperature cold iron is also relatively poor; secondly, the isolated hot nodes of some castings are in the middle part, and the solidification rate at the isolated hot node cannot be controlled by dipping the mold shell in water; therefore, the treatment of isolated hot nodes of investment castings is often a thorny problem. When spraying water for cooling, a large amount of water is often required, which easily causes a waste of water resources. The cooling water needs to be recycled, and after the product comes into contact with the air, an oxide layer will be generated. The participation of the oxide layer in the circulation can easily cause pipeline blockage, so we proposed a cooling water spray equipment for casting products. Summary of the invention

[0004] A housing, and a base plate disposed at the bottom of the housing;

The sprayed water The oxide layer is broken up and finally enters the inside of the shell. As part of the oxide layer is sprayed out of the placement component and then filtered by the filter plate, large oxide layers are prevented from entering the inside of the shell and clogging of the pipeline component is avoided. Finally, the filter component filters the fine oxide layer to prevent the fine oxide layer from participating in the circulation of the cooling mechanism and clogging of the pipeline. The semicircular cover can shield the cooling pipe during spraying, thereby reducing the water spraying range and concentrating the sprayed water to prevent the cooling water from being sprayed everywhere and splashing everywhere. The cover causes the cooling water to spray downward, thereby contacting the oxide layer at a better angle, so that the oxide layer is concentrated inside the placement component, and the oxide layer is broken up under continuous spraying to avoid the generation of a large number of large oxide layers, thereby avoiding clogging of the filter holes.

[0014] Furthermore, several cooling pipes are arranged on the surface of the filter plate, and several cooling pipes are arranged corresponding to the cover body, several placement components are arranged at the intervals between the cooling pipes, and several filter holes are evenly arranged on the surface of the filter plate. Multiple placement components are arranged to place several cast products and cool multiple cast products at one time. Multiple cooling pipes and the cover body, and the placement components are arranged at the intervals between the cooling pipes, can spray water on the cast products at multiple angles, thereby better cooling the cast products.

[0015] Furthermore, a groove is provided on the surface of the cooling pipe located inside the cover body, and the groove is inclined. A plurality of grooves are arranged along the circumference of the cooling pipe. The surface of the cooling pipe is rotatably connected with fan blades, and the fan blades are inclined. The inclination direction of the fan blades is opposite to the inclination direction of the groove. Cooling water is sprayed from the groove and then sprayed along the gaps of the fan blades, thereby spraying onto the surface of the cast product to cool the cast product. Since the groove is inclined, the fan blades are driven to rotate, and the rotating fan blades can spray the cooling water evenly, thereby obtaining a larger cooling range and a better cooling effect. The inclination directions of the groove and the fan blades are opposite, so that the cooling water sprayed from the groove is perpendicular to the fan blades, thereby better driving the fan blades to rotate, making the rotation speed of the fan blades faster, and making the cooling water spray more evenly.

[0016] Furthermore, a circular plate is provided inside the cover body, and the surface of the circular plate is rotatably connected to the inner wall of the cover body. The surface of the circular plate is fixedly connected to the side of the fan blade away from the cover body, and the circular plate has a gap at the position where the fan blades are located. The fan blades rotate, driving the circular plate to rotate, and finally ejected through the gap of the circular plate. The circular plate is provided to seal the bottom part of the cover body, reduce the injection area, thereby increasing the injection force and ensuring the breakage of the oxide layer.

[0017] Furthermore, the pipeline assembly includes a bent pipe, which is fixedly connected to a side of the filter plate away from the cooling pipe, and an end of the bent pipe close to the filter plate penetrates the filter plate and is fixedly connected to an end of the cooling pipe away from the cover body. Small holes are provided on the surface of the bent pipe to drive the water inside the bent pipe to flow, thereby directing the water inside the outer shell into the small holes, and finally entering the cooling pipe, and finally spraying out through the trough body. After cooling the cast product, it enters the outer shell through the filter hole, completing the recycling of cooling water. The setting of the small holes can filter the oxide layer, prevent the oxide layer from entering the inside of the bent pipe, and prevent the fine oxide layer from participating in the circulation, thereby avoiding blockage.

[0018] Furthermore, several cooling pipes are arranged corresponding to the curved pipes, and a first connecting pipe is symmetrically arranged at the interval between two curved pipes in the middle, and the ends of the two first connecting pipes away from each other are fixedly connected to the surface of the cooling pipe, and a pump body is arranged at the interval between the two first connecting pipes, and the ends of the two first connecting pipes close to each other are fixedly connected to the surface of the pump body, and a second connecting pipe is arranged on the side of the two first connecting pipes away from the pump body, and the second connecting pipe is arranged at the interval between the two first connecting pipes, and the two ends of the second connecting pipe are respectively fixedly connected to the surfaces of the two curved pipes, and the pump body is started, and the first connecting pipe and the second connecting pipe connect the several curved pipes, so that the pump body drives the cooling water inside the several curved pipes to flow at the same time, so that the several cooling pipes spray water at the same time, ensuring uniform cooling when cooling multiple cast products.

[0019] Furthermore, the placement component includes a disk body, the inner wall of the disk body is set to be conical, the side of the disk body away from the cover body is fixedly connected to the side of the filter plate close to the cover body, a circular hole is opened at the center of the inner wall of the disk body, and the circular hole passes through the disk body and the filter plate in sequence, and the cast product is placed inside the disk body. The conical inner wall of the disk body can hold cast products of different sizes, and a gap is left at the bottom of the cast product to ensure that the bottom of the cast product can contact the cooling water, and finally the oxide layer is broken by the cooling water. Finally, as the cooling water enters the interior of the shell through the circular hole, the conical inner wall of the disk body can make the oxide layer with larger mass accumulate to its bottom, ensuring that the oxide layer can quickly leave the disk body and avoiding the oxide layer from splashing out of the disk body.

[0020] Furthermore, a rubber strip is fixedly connected to the inner wall of the disk body, and the rubber strip is arranged in a corrugated shape. A plurality of the rubber strips are arranged along the circumference of the disk body, and seepage holes are arranged at the intervals between adjacent rubber strips. Cooling water leaves the disk body through the seepage holes to avoid a large amount of water causing a large amount of water inside the disk body, to avoid the oxide layer floating up with the cooling water, to avoid the oxide layer leaving the disk body, to ensure that the oxide layer can smoothly enter the interior of the outer shell, and to set the rubber strip. After the cast product is placed, the rubber strip can increase the friction coefficient with the cast product, to avoid the cast product from being offset inside the disk body, and to ensure uniform cooling of the cast product.

[0021] Furthermore, the filter assembly includes an inclined plate, which is inclined toward a side close to the elbow, and the surface of the inclined plate is fixedly connected to the inner wall of the shell.

After the placement is completed, the telescopic rod is driven to make the frame and the top of the shell sealed and contact, so as to avoid splashing of cooling water when spraying water.

[0023] The present invention has the beneficial effects:

[0024] 1. The present invention sets a cooling mechanism, and water enters the cover through a cooling pipe, and then is sprayed out from the bottom of the cover, and then is sprayed on the surface of the cast product to cool the cast product and solve the shrinkage cavity. The sprayed water breaks up the oxide layer and finally enters the shell. Since the sprayed part of the oxide layer is ejected out of the placement component and then filtered by the filter plate, it is prevented that a large piece of oxide layer enters the shell and the pipeline component is blocked. Finally, the filter component filters the fine oxide layer to prevent the fine oxide layer from participating in the circulation of the cooling mechanism and the pipeline is blocked. The semicircular cover can shield the cooling pipe during spraying, thereby reducing the water spraying range, concentrating the sprayed water, avoiding the cooling water from being ejected everywhere, and avoiding the cooling water from splashing everywhere. The cover prompts the cooling water to spray downward, thereby contacting the oxide layer at a better angle, so that the oxide layer is concentrated inside the placement component, and the oxide layer is broken under continuous spraying to avoid the generation of a large number of large oxide layers, thereby avoiding the clogging of the filter holes.

[0025] 2. The present invention sets a trough body. Due to the inclined setting of the trough body, the fan blades are driven to rotate. The rotating fan blades can spray the cooling water evenly, thereby obtaining a larger cooling range and a better cooling effect. The inclination direction of the trough body and the fan blades is opposite, so that the cooling water sprayed from the trough body is perpendicular to the fan blades, thereby better driving the fan blades to rotate, making the fan blades rotate faster and the cooling water sprayed more evenly. A circular plate is set to seal the bottom part of the cover body and reduce the spraying area, thereby increasing the spraying force and ensuring the breakage of the oxide layer.

[0026] 3. The present invention sets a placement component, and the conical inner wall of the disk can place casting products of different sizes. A gap is left at the bottom of the casting product to ensure that the bottom of the casting product can contact the cooling water. Finally, the oxide layer is broken by the cooling water, and finally as the cooling water enters the interior of the shell through the circular hole, the conical inner wall of the disk can make the oxide layer with larger mass accumulate to its bottom, ensuring that the oxide layer can quickly leave the disk, avoiding the oxide layer from splashing out of the disk. The cooling water leaves the disk through the seepage hole, avoiding a large amount of water causing more water inside the disk, avoiding the oxide layer from floating up with the cooling water, avoiding the oxide layer from leaving the disk, ensuring that the oxide layer can smoothly enter the interior of the shell, and setting a rubber strip. After the casting product is placed, the rubber strip can increase the friction coefficient with the casting product, avoiding the casting product from deflecting inside the disk, and ensuring uniform cooling of the casting product.

[0027] 4. The present invention sets an inclined plate so that the heavier oxide layer slides down to the surface of the pumping plate along the inclined plate. The oxide layer slides down along the inclined plate that is inclined toward the side of the curved pipe, thereby keeping the oxide layer away from the curved pipe to avoid the oxide layer being sucked into the curved pipe. The setting of the elliptical holes can filter out excess moisture to avoid the oxide layer from being suspended during pumping. The narrow and long elliptical holes can filter out the fine oxide layer to avoid the oxide layer remaining inside the outer shell. BRIEF DESCRIPTION OF THE DRAWINGS

Finally, the filter component 37 filters the fine oxide layer to prevent the fine oxide layer from participating in the circulation of the cooling mechanism 3 and clogging of the pipeline. The semicircular cover 32 can shield the cooling pipe 31 during spraying, thereby reducing the water spraying range, concentrating the sprayed water, avoiding the cooling water from being ejected everywhere, and avoiding the cooling water from splashing everywhere.
