Description

Technical Field

[0001] This utility model belongs to the field of iron mold sand casting technology, and specifically relates to a cooling device for iron mold sand casting. Background Technology

[0002] Iron mold sand casting, as an advanced process, produces castings with advantages such as dense structure and high dimensional accuracy. However, after demolding, it still faces the common problem of difficult-to-clean residual sand on the surface of high-temperature castings, especially the removal of sand in complex cavities and inner holes.

[0003] The current industry standard of natural cooling followed by centralized cleaning has revealed disadvantages such as low production efficiency, large space occupation, and long production cycles. While traditional drum cleaning machines can simultaneously cool and remove sand, their working principle involves placing a large number of high-temperature castings inside the drum and removing sand through tumbling and collision. This inevitably leads to mutual collisions, scratches, and even deformation between castings, significantly impacting the yield of precision castings. Furthermore, the accumulation of castings inside the drum prevents the cooling medium from evenly covering all surfaces, easily causing internal stress, deformation, or cracks in the castings due to uneven cooling. At the same time, this process is accompanied by severe noise and dust pollution, deteriorating the working environment.

[0004] To address the issue of collision damage, existing technologies have also developed devices that use fixed nozzles to cool and clean stationary castings. While this avoids direct collisions, the stationary nature of the castings creates dead zones in the spraying process, making it difficult to ensure uniform cooling and thorough sand removal for the complex contours and internal cavities of the castings. Furthermore, the sand particles washed off are difficult to recycle and dispose of after mixing with the cooling water, resulting in resource waste and environmental hazards. Utility Model Content

[0005] The purpose of this utility model is to provide a cooling device for castings made by iron mold sand coating, which can perform uniform, efficient and non-destructive cooling and sand removal on the castings, and can realize the effective recycling of waste sand.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cooling device for castings made by iron mold sand casting includes: a mounting box, an mounting plate fixedly installed on the inner side wall of the mounting box, a rotating plate rotatably installed on the mounting plate, two symmetrically arranged perforated mesh plates rotatably installed on the rotating plate, a cooling fan rotatably installed on the back of the mounting box, a rotating assembly provided on the rotating plate, a collection assembly provided below the perforated mesh plates, and a spraying mechanism provided above the perforated mesh plates;

[0008] The spraying mechanism includes a ring-shaped mounting frame with a lifting assembly. A partition plate is fixedly installed on the inner sidewall of the mounting frame, dividing the interior of the mounting frame into a rinsing chamber and an atomizing chamber from top to bottom. Multiple atomizing nozzles and high-pressure nozzles are fixedly installed on the bottom and inner sidewall of the mounting frame, respectively. The multiple atomizing nozzles and high-pressure nozzles are arranged in a ring at equal intervals and tilted downwards towards the center of the mounting frame. The atomizing nozzles are connected to the atomizing chamber, and the high-pressure nozzles are connected to the rinsing chamber.

[0009] Preferably, a first water inlet pipe and a second water inlet pipe are fixedly provided on the outer wall of the mounting frame, the first water inlet pipe is connected to the atomizing chamber, and the second water inlet pipe is connected to the rinsing chamber. The water inlet ends of the first water inlet pipe and the second water inlet pipe both pass through the mounting box and are fixedly provided with connectors.

[0010] Preferably, the lifting assembly includes two connecting plates fixedly mounted on the top of the mounting frame. Both connecting plates are L-shaped. Multiple guide rods are slidably mounted through the connecting plates. The top and bottom of the multiple guide rods are fixedly connected to the top and inner sidewall of the mounting box, respectively. Two symmetrically arranged hydraulic rods are fixedly mounted on the top of the mounting box. The bottom of the two hydraulic rods are fixedly connected to the top of the corresponding two connecting plates, respectively.

[0011] Preferably, the rotating assembly includes a rotating rod fixedly mounted on the top of the rotating plate, the top of the rotating rod being rotatably connected to the top of the mounting box, a reduction motor being fixedly mounted on the top of the mounting box, a rotating shaft being fixedly mounted on the output end of the reduction motor, and the bottom of the rotating shaft being fixedly connected to the top of the rotating rod.

[0012] Preferably, the collection assembly includes a collection frame disposed at the bottom of the mounting box, and a flow guide shroud adapted to two perforated mesh plates is disposed directly above the collection frame, with the top of the flow guide shroud and the bottom of the rotating plate being fixedly connected.

[0013] Preferably, a fixing frame is provided inside the collection frame, and a filter screen is fixedly installed on the fixing frame.

[0014] Preferably, a water pump is fixedly installed on the outer wall of the mounting box, a water outlet pipe is fixedly installed between the water inlet end of the water pump and the bottom of the collection frame, and a drain pipe is fixedly installed at the water outlet end of the water pump.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By using a rotatable perforated plate to support the castings, and in conjunction with ring-shaped atomizing nozzles and high-pressure nozzles, the system can achieve multi-angle, dead-angle-free, uniform cooling and rinsing of the castings. This effectively avoids the casting damage caused by impacts during traditional drum cleaning and the cooling dead-angle problems of fixed spraying. The height of the mounting frame can be adjusted by the lifting component to adapt to the processing needs of castings of different sizes, improving the applicability of the device. Pre-cooling is achieved using a cooling fan, combined with the evaporative cooling of the atomizing nozzles and the powerful rinsing of the high-pressure nozzles, forming a staged cooling and sand removal process. This prevents the castings from cracking due to rapid cooling and ensures that residual sand is completely removed. The design of the collection component and guide hood allows for the effective collection of waste sand and cooling water, and the sand-water separation and resource recycling are achieved through the filter screen, reducing environmental pollution.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figure 1- Figure 5 As shown, a cooling device for castings made by iron mold sand casting includes: a mounting box 1, a mounting plate 2 fixedly installed on the inner side wall of the mounting box 1, a rotating plate 3 rotatably installed through the mounting plate 2, two symmetrically arranged perforated mesh plates 4 rotatably installed through the rotating plate 3, a heat dissipation fan 5 rotatably installed through the back of the mounting box 1, a rotating component on the rotating plate 3, a collection component below the perforated mesh plates 4, and a spraying mechanism above the perforated mesh plates 4;

[0026] The spraying mechanism includes a ring-shaped mounting frame 6, a lifting assembly on the mounting frame 6, a partition plate 7 fixedly installed on the inner side wall of the mounting frame 6, the partition plate 7 dividing the interior of the mounting frame 6 from top to bottom into a rinsing chamber and an atomizing chamber, a plurality of atomizing nozzles 8 and high-pressure nozzles 9 fixedly installed on the bottom and inner side wall of the mounting frame 6 respectively, the plurality of atomizing nozzles 8 and high-pressure nozzles 9 are arranged in a ring at equal intervals and tilted downward toward the center of the mounting frame 6, the atomizing nozzles 8 are connected to the atomizing chamber, and the high-pressure nozzles 9 are connected to the rinsing chamber;

[0027] The outer side wall of the mounting frame 6 is fixedly provided with a first water inlet pipe 10 and a second water inlet pipe 11. The first water inlet pipe 10 is connected to the atomizing chamber, and the second water inlet pipe 11 is connected to the rinsing chamber. The water inlet ends of the first water inlet pipe 10 and the second water inlet pipe 11 both pass through the mounting box 1 and are fixedly provided with connectors 12.

[0028] As can be seen from the above, by setting up independent rinsing chambers and atomizing chambers, and cooperating with the annularly distributed atomizing nozzles 8 and high-pressure nozzles 9, the castings can be processed in stages. The atomizing nozzles 8 first perform uniform atomization cooling on the high-temperature castings to avoid cracks caused by rapid cooling. The high-pressure nozzles 9 then perform powerful rinsing on the surface of the castings to thoroughly remove residual sand. The rotating plate 3 drives the castings on the perforated plate 4 to rotate at a uniform speed to ensure that the cooling medium can cover all surfaces of the castings and eliminate processing dead corners. The cooling fan 5 pre-cools the castings before spraying to improve the overall processing efficiency.

[0029] The working process of this utility model device is as follows: First, the high-temperature casting after demolding is placed on the perforated plate 4, and the cooling fan 5 is started to perform preliminary air cooling of the casting. The top and side walls of the mounting box 1 are equipped with heat dissipation vents adapted to the cooling fan 5 (not shown in the figure, and dustproof nets are set on the heat dissipation vents); then, the atomizing nozzle 8 performs uniform atomized spray cooling on the casting. This staged cooling method can effectively avoid cracks in the casting due to rapid cooling; after the preliminary cooling is completed, the lifting component drives the mounting frame 6 to move downward along the guide rod 14 in multiple segments through the telescopic movement of the hydraulic rod 15. By adjusting the oil supply of the hydraulic rod 15 through the hydraulic control system, the mounting frame 6 can be accurately stopped at multiple positions during the descent, so that the high-pressure nozzle 9 can perform full-coverage rinsing of the casting in layers and areas. This segmented adjustment mechanism ensures that the surface of the casting with different height characteristics can obtain the best rinsing effect; at the same time, the rotating component drives the rotating plate 3 to rotate at a uniform speed through the reduction motor 17, so that all surfaces of the casting can be fully covered by the rinsing medium and the residual sand can be thoroughly removed.

[0030] Connector 12 is connected to the external water supply pipeline and the air supply pipeline respectively. The connector 12 connected to the first water inlet pipe 10 is connected to the atomizing medium supply system. In this system, cooling water and compressed air are pre-mixed in an external mixing device to form an aerosol mixture, which is then transported to the atomizing chamber through connector 12 and sprayed out by the atomizing nozzle 8. The connector 12 connected to the second water inlet pipe 11 is connected to the output end of the high-pressure water pump, which transports high-pressure cooling water through connector 12 to the rinsing chamber and sprays it out by the high-pressure nozzle 9. This separate supply system ensures that the two spraying media do not interfere with each other, and the pressure and flow rate can be adjusted independently to meet the different requirements of the medium form and impact force in different cooling stages.

[0031] Specifically, regarding the aforementioned lifting and rotating components, the lifting component includes two connecting plates 13 fixedly mounted on the top of the mounting frame 6. Both connecting plates 13 are L-shaped. Multiple guide rods 14 are slidably mounted through the connecting plates 13. The top and bottom of the multiple guide rods 14 are fixedly connected to the top and inner sidewall of the mounting box 1, respectively. Two symmetrically arranged hydraulic rods 15 are fixedly mounted on the top of the mounting box 1. The bottom of the two hydraulic rods 15 are fixedly connected to the top of the corresponding two connecting plates 13, respectively.

[0032] The rotating assembly includes a rotating rod 16 fixedly mounted on the top of the rotating plate 3. The top of the rotating rod 16 is rotatably connected to the top of the mounting box 1. A reduction motor 17 is fixedly mounted on the top of the mounting box 1. A rotating shaft 18 is fixedly mounted on the output end of the reduction motor 17. The bottom of the rotating shaft 18 is fixedly connected to the top of the rotating rod 16.

[0033] As can be seen from the above, the lifting assembly drives the mounting frame 6 to move up and down along the guide rod 14 through the telescopic movement of the hydraulic rod 15, so that the atomizing nozzle 8 and the high-pressure nozzle 9 can be adjusted to the optimal working distance according to the shape and size of the casting, ensuring that castings of different specifications can obtain uniform cooling and rinsing effects.

[0034] The rotating assembly drives the rotating shaft 18 and rotating rod 16 to rotate synchronously through the geared motor 17, which in turn drives the castings on the rotating plate 3 and the perforated plate 4 to rotate at a uniform speed, so that all surfaces of the castings can fully receive the effect of the cooling medium, and completely solves the problem of dead corners in the fixed spraying.

[0035] Example 2:

[0036] The collection component includes a collection frame 19 located at the bottom of the mounting box 1, and a flow guide hood 20 adapted to two perforated mesh plates 4 located directly above the collection frame 19. The top of the flow guide hood 20 and the bottom of the rotating plate 3 are fixedly connected.

[0037] The collection frame 19 is equipped with a fixing frame 21, and a filter screen 22 is fixedly installed on the fixing frame 21;

[0038] A water pump 23 is fixedly installed on the outer wall of the mounting box 1. A water outlet pipe 24 is fixedly installed between the water inlet end of the water pump 23 and the bottom of the collection frame 19. A drain pipe 25 is fixedly installed at the water outlet end of the water pump 23.

[0039] As can be seen from the above, the collection component uses the guide shroud 20 to collect the used cooling water and the washed-down waste sand into the collection frame 19. The filter screen 22 effectively separates the sand and water, which facilitates the recycling of waste sand and the circulation of cooling water. The water pump 23 extracts the cooling water from the collection frame 19 through the outlet pipe 24 and discharges it through the drain pipe 25 or transports it to the circulation system, realizing the reuse of water resources. This reduces production costs and wastewater discharge, which is in line with the concept of green and environmentally friendly production.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
