Description

Technical Field

[0001] This utility model relates to the field of casting mold technology, and in particular to a high-efficiency sand mixing casting mold. Background Technology

[0002] Sand mixing molds are essential tools in sand casting for creating molds. Sand mixing involves thoroughly mixing new sand, old sand, binder, hardener, and additives in a specific ratio, ensuring the binder and additives evenly coat the sand grains to form high-performance molding sand or core sand. Molding involves filling the mold cavity with the mixed molding sand, compacting it through methods such as pressing and vibration, and then removing the mold to obtain a sand mold with the same shape as the mold cavity. Pouring involves pouring molten metal into the sand mold cavity, where it cools and solidifies, forming a casting that matches the shape of the mold.

[0003] In existing technologies, during the casting process, gases in the molding sand need to be released in a timely manner to avoid defects such as porosity and sand holes in the casting. However, the released gases usually contain some harmful gases, such as phenolic resin, which decompose at high temperatures to produce volatile organic compounds such as formaldehyde, benzene, and toluene. These substances have irritating odors and can irritate the eyes and respiratory tract. Long-term exposure may lead to symptoms such as dizziness and nausea, affecting the health of surrounding workers. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that the gas discharged during the casting process usually contains some harmful gases, which affects the health of the surrounding workers, and proposes a high-efficiency sand casting mold.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1, as Figures 1-5 As shown, this utility model provides a high-efficiency sand casting mold, including an upper mold 1. Two venting grooves 10 are formed on the outer wall of the upper mold 1, and venting holes 11 are formed through the inner wall of each venting groove 10. A fixing pipe 12 is fixedly installed at one end of the upper mold 1 near the venting grooves 10, and an venting pipe 13 is fixedly installed at one end of the fixing pipe 12. A fan 6 is installed at one end of the venting pipe 13. An air inlet pipe 8 is fixedly installed at the input end of the fan 6, and an air outlet pipe 7 is fixedly installed at the output end of the fan 6. A purification box 5 is installed at one end of the fan 6, and one end of the air outlet pipe 7 enters the purification box 5 and is fixedly connected to it. The bottom of the chamber 5 has a through-hole air outlet 16. The top of the purification chamber 5 is fixedly installed with a motor 14. The output end of the motor 14 enters the purification chamber 5 and is fixedly installed with a rotating plate 15. Both ends of the rotating plate 15 are fixedly installed with a placement frame 17. The placement frame 17 is filled with an activated carbon plate 18. The inner wall of the purification chamber 5 has a through-hole 20. The inner wall of the opening 20 has a storage slot 21. The inner wall of the storage slot 21 has a through-hole threaded hole 22. The threaded hole 22 is threadedly connected to a threaded rod 23. The top of the threaded rod 23 is fixedly installed with a handle 24. The bottom of the threaded rod 23 is movably connected with a baffle 25.

[0027] The overall effect of Embodiment 1 is as follows: during exhaust, the generated gas enters the exhaust trough 10 through the exhaust port 11 and finally enters the fixed pipe 12. The operator starts the fan 6, and the intake pipe 8 sends the exhaust gas into the exhaust pipe 7 through the exhaust pipe 13. After being filtered and purified by the activated carbon plate 18, the purified air leaves from the exhaust port 16. When the activated carbon plate 18 needs to be replaced, the operator starts the motor 14, and the rotating plate 15 rotates 180 degrees. The new activated carbon plate 18 moves above the exhaust port 16. The operator rotates the handle 24, and the threaded rod 23 rises, thereby driving the baffle 25 into the storage tank 21. At this time, the operator can take out the activated carbon plate 18 for replacement. In this way, the replacement can be carried out without stopping the machine, which improves the purification efficiency.

[0028] Example 2, as Figures 1-5As shown, a connecting block 27 is fixedly installed on the outer wall of the intake pipe 8. A slot 28 is opened on the outer wall of the connecting block 27. A limiting groove 29 is opened on the inner wall of the slot 28. A spring 30 is fixedly installed on the inner wall of the limiting groove 29. A locking block 31 is fixedly installed at the bottom of the spring 30. A connecting rod 32 is fixedly installed at the top of the locking block 31. The top of the connecting rod 32 passes through the connecting block 27 and is fixedly installed with a pull plate 33. When the operator pulls the pull plate 33, the pull plate 33 drives the locking block 31 to move through the connecting rod 32, thereby compressing the spring 30.

[0029] Furthermore, a fixing block 26 is fixedly installed on the outer wall of the exhaust pipe 13, and an insert plate 34 is fixedly installed on the outer wall of the fixing block 26. A slot 35 is opened on the top of the insert plate 34. The outer wall of the locking block 31 fits against the inner wall of the slot 35, and the outer wall of the insert plate 34 fits against the inner wall of the slot 28. When the locking block 31 enters the slot 35, the insert plate 34 can be fixed in place to prevent the insert plate 34 from shaking.

[0030] Furthermore, a sealing groove 36 is provided at one end of the air intake pipe 8, and a sealing ring 37 is fixedly installed on the inner wall of the sealing groove 36, which increases the sealing performance and reduces the probability of air leakage.

[0031] Furthermore, a lower mold 2 is provided at the bottom of the upper mold 1, and an inner cavity 9 is provided on the opposite side of the upper mold 1 and the lower mold 2 for liquid metal forming.

[0032] Furthermore, a support frame 38 is fixedly installed on the outer wall of the placement frame 17 to provide support for the activated carbon plate 18, prevent the activated carbon plate 18 from tilting, and reduce the pressure on the placement frame 17.

[0033] Furthermore, a filter screen 19 is fixedly installed at the bottom of the purification box 5 to prevent external dust from entering the purification box 5 through the air outlet 16, thus reducing the difficulty of cleaning for staff.

[0034] Furthermore, a feed pipe 3 is installed through and fixedly mounted on the top of the upper mold 1, which is used by workers to pour the molten liquid metal into the inner cavity 9.

[0035] Furthermore, a support plate 4 is fixedly installed on the outer wall of the upper mold 1. When installing the purification box 5, the bottom of the purification box 5 is placed on the support plate 4. By supporting the purification box 5, the pressure of the air inlet pipe 8 is reduced.

[0036] Furthermore, the outer wall of the baffle 25 is in contact with the inner wall of the storage groove 21 to prevent the baffle 25 from rotating when the threaded rod 23 rotates, thus providing a limiting effect on the baffle 25.

[0037] The effect achieved by the entire embodiment 2 is that when it is necessary to replace another upper mold 1, the operator pulls the pull plate 33, and the pull plate 33 drives the locking block 31 away from the slot 35 through the connecting rod 32. Then the air intake pipe 8 can be removed, and the sealing groove 36 is put on the exhaust pipe 13 next to the new upper mold 1. When one end of the exhaust pipe 13 contacts the sealing ring 37, the insert plate 34 enters the slot 28. The operator releases the pull plate 33, and the elastic force of the spring 30 pushes the locking block 31 into the slot 35, thus completing the installation and improving the efficiency of installation and disassembly.

[0038] Working principle: During use, the operator places the upper mold 1 on top of the lower mold 2. The operator pours the molten liquid metal into the inner cavity 9 through the feed pipe 3. The generated gas enters the exhaust trough 10 through the exhaust port 11 and finally enters the fixed pipe 12. The operator starts the fan 6, and the exhaust pipe 8 sends the exhaust gas into the exhaust pipe 7 through the exhaust pipe 13. Finally, after being filtered and purified by the activated carbon plate 18, the purified air leaves from the exhaust port 16. When the activated carbon plate 18 needs to be replaced, the operator starts the motor 14, and the rotating plate 15 rotates 180 degrees. The new activated carbon plate 18 moves above the exhaust port 16. The operator rotates the handle 24, and the threaded rod 23 rises, thereby driving the baffle 25 into the storage tank 21. At this time, the operator can take out the activated carbon plate 18 for replacement. In this way, the replacement can be carried out without stopping the machine, which improves the purification efficiency. When it is necessary to replace another upper mold 1, the operator pulls the pull plate 33. The pull plate 33 drives the locking block 31 away from the slot 35 through the connecting rod 32. Then the air intake pipe 8 can be removed, and the sealing groove 36 is put on the exhaust pipe 13 next to the new upper mold 1. When one end of the exhaust pipe 13 contacts the sealing ring 37, the insert plate 34 enters the slot 28. The operator releases the pull plate 33, and the elastic force of the spring 30 pushes the locking block 31 into the slot 35, thus completing the installation and improving the efficiency of installation and disassembly.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
