Description

Technical Field

[0001] The utility model relates to the technical field of metal product processing equipment, in particular to a demoulding device for casting metal products. Background Art

[0002] Metal products refer to various items made of processed metal materials, which can be pure metal or alloy. Metal products are widely used in industry, construction, transportation, home furnishing and other fields, such as machine parts, building materials, transportation tools, daily necessities, etc.

[0003] Casting is a way of producing metal products. After searching, the Chinese patent application number is: CN202122308671.2, which relates to a demolding device for cold forging of metal products, including a box body, a base plate fixedly installed at the bottom end of the box body, a support frame fixedly installed at the bottom end of the base plate, and a mold fixedly installed at the top end of the box body. It also includes a demolding structure installed in the box body, and the demolding structure is composed of a rotating component, a pushing component and a transmission component. The top of the pushing component is slidably connected to the inner wall of the mold, and the right side of the bottom end of the pushing component is connected to the left end of the rotating component. The high-pressure gas of the utility model is transmitted to the mold through the transmission component, so that the outer wall of the material is separated from the inner wall of the mold, and the rotating rod 2 is driven to rotate by the rotating component. The rotation of the rotating rod 2 and the threaded connection between the top of the rotating rod 2 and the inner wall of the connecting sleeve push the connecting sleeve to rise along the limit rod, and the push plate is pushed to push the material out of the mold, so as to realize demolding and improve efficiency.

[0004] The Chinese patent application number is: CN202221285511.9, which discloses a metal product mold that is easy to demould quickly, including a lower mold, a cavity is arranged at the bottom of the lower mold, a lifting assembly is arranged at the top of the cavity, positioning grooves are arranged on both sides of the lower mold, two groups of telescopic rods are slidably arranged at the bottom of the positioning grooves, the top of the outer sides of the two groups of telescopic rods are sleeved with second springs, the bottom of the two groups of telescopic rods close to each other is hinged with a hinged rod, and slide plates are slidably arranged on both sides of the bottom of the cavity. The utility model device can cooperate with the first contact block and the second contact block to push the push rod and the top plate upward through the elastic force of the two groups of second springs and the first spring when unloading, so that the stamping shell inside the lower mold can be pushed out upward, so that the metal product can be automatically ejected after the stamping is completed, greatly reducing the manual demoulding of the metal product.

[0005] The above technical solution is to eject the molded product from the bottom of the mold by modifying the mold. This method not only requires damage to the mold, resulting in incompleteness of the mold, but also has a high modification cost. Therefore, we need to propose a demoulding device for casting metal products. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4 , the utility model provides a technical solution:

[0028] A demoulding device for casting metal products, comprising:

[0029] A base 1; a panel 2 for placing a building mold is provided on the base 1, and the panel 2 is attached to the mold;

[0030] Cooling mechanism: The cooling mechanism includes a jacket 8 arranged on the outer wall of the enclosure 2 and a water tank 9 arranged on one side of the base 1. A cooling pump 10 is installed on the outer wall of the water tank 9 to supply water to the jacket 8. A return pipe 13 is arranged on the outer wall of the jacket 8, and the end of the return pipe 13 extends to the inside of the water tank 9. The water inlet end of the cooling pump 10 is fixedly connected to the water inlet pipe 11, and the end of the water inlet pipe 11 extends to the inner bottom of the water tank 9. Check valves are installed on the water inlet pipe 11 and the return pipe 13. A partition 16 is arranged on the inner wall of the jacket 8, and the return pipe 13 is located on one side of the partition 16. The water outlet end of the cooling pump 10 is fixedly connected to the water outlet pipe 12, which is connected to the inner cavity of the jacket 8 and is located on the other side of the partition 16.

[0031] The auxiliary demoulding mechanism is also included. The auxiliary demoulding mechanism includes a support plate 3 arranged on the base 1, the support plate 3 is arranged in a U-shape, and a storage barrel 4 for storing a demoulding agent is arranged on the top of the support plate 3. A demoulding pump 5 is installed at the bottom of the support plate 3, the liquid inlet end of the demoulding pump 5 is connected to the inner cavity of the storage barrel 4 through a pipeline, and the liquid outlet end of the demoulding pump 5 is connected to a nozzle 6 through a pipeline, and the bottom surface of the nozzle 6 is honeycomb-shaped with multiple groups of nozzles 7, and the nozzle 6 and the enclosure 2 are coaxially arranged.

[0032] A panel 2 is arranged on the base 1 for placing the casting mold, and a cooling mechanism including a jacket 8 and a water tank 9 is arranged. The water tank 9 supplies water to the jacket 8 through a cooling pump 10, and the water flows back to the water tank 9 through a reflux pipe 13 to form a circulation. In addition, an auxiliary demoulding mechanism including a storage barrel 4 is arranged. The storage barrel 4 sprays a demoulding agent into the mold through a demoulding pump 5.

[0033] In general, the device has a simple structure and is easy to use. Through the cooperation of the cooling mechanism and the auxiliary demoulding mechanism, it has a reasonable cooling system, which makes the temperature difference between the inside and outside of the mold moderate, which is conducive to rapid curing and demoulding. At the same time, the release agent reduces the friction of the inner wall of the mold and reduces the difficulty of demoulding.

[0034] In actual use, the casting mold is placed in the enclosure 2, which is a copper enclosure 2, and the enclosure 2 is attached to the outer wall of the mold. Before pouring, the demoulding pump 5 is started to extract the demoulding agent in the storage barrel 4 and spray it in the mold. After pouring, the cooling pump 10 is started. The cooling pump 10 extracts cold water in the water tank 9 and transports it to the jacket 8 outside the enclosure 2 through a water pipe. After circulating in the jacket 8 for one circle, it returns to the water tank 9 through the reflux pipe 13. In this process, the mold is heat exchanged by water flow. On the one hand, the mold can be cooled comprehensively and evenly, so that the temperature difference between the inside and outside of the mold is moderate, which is conducive to rapid solidification and demoulding. On the other hand, the use of a circulating mode for cooling can reduce the waste of water resources and reduce the demoulding cost. After the metal product is formed, it can be demoulded quickly.

[0035] Also, see Figure 1-2 :

[0036] A semiconductor refrigeration sheet 14 is also installed on the water tank 9 . A heat absorbing rod 15 is provided on the heat absorbing surface of the semiconductor refrigeration sheet 14 . The heat absorbing rod 15 extends below the liquid level in the water tank 9 .

[0037] By installing a semiconductor refrigeration sheet 14 on the water tank 9, the water in the water tank 9 can be continuously cooled during the use of the equipment, so that the water in the water tank 9 always maintains a low temperature. When the cooling pump 10 supplies water to the jacket 8, the cooling capacity can be improved, and the metal product forming efficiency can be improved, which has a high practical value.

[0038] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
