Description

Technical Field

[0001] This utility model relates to the field of steel casting technology, and in particular to a steel casting mold that is easy to demold. Background Technology

[0002] Steel casting molds are tools or equipment used to manufacture steel castings. During the casting process, liquid metal is poured into a mold cavity of a specific shape, and after it cools and solidifies, the desired casting is formed.

[0003] Patent CN213729200U discloses a steel casting mold with a limiting function. It includes an upper mold and a lower mold, with the upper mold placed on top of the lower mold. Both the bottom of the upper mold and the top of the lower mold have cavities. A telescopic groove is formed at the edge of the top of the lower mold, and a movable sealing seat is movably installed within the telescopic groove. Several sealing strips are fixedly installed on the top of the movable sealing seat. When using this patent, the upper and lower molds are connected by bolts to a fixed plate, and casting is performed through a pouring channel. However, in the aforementioned prior art, after the liquid metal is poured, the cooled casting adheres tightly to the inside of the mold, requiring tools to remove it, which can easily scratch the surface of the casting.

[0004] In view of the existing patents, there is a need to provide a mold for steel casting that is easy to demold. Utility Model Content

[0005] To overcome the shortcomings of existing patents where the cooled castings adhere tightly to the mold after the liquid metal is poured, requiring tools to remove them and easily causing scratches on the surface of the castings, this utility model provides a steel casting mold that facilitates demolding. By using components such as a vibrating shell, a second vibrating plate, and a micro vibrator, the adhesion between the castings and the mold is reduced, making it easier to remove the castings from the mold.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a steel casting mold that facilitates demolding, comprising a base plate, a panel, a rear mold blank, a front mold blank, and a template. The rear mold blank is fixedly connected to the base plate, and the template is embedded in the rear mold blank. The front mold blank covers the rear mold blank, and the panel is fixedly connected to the front mold blank. The mold also includes a first vibrating plate, a transmission frame, a vibrating housing, a second vibrating plate, and a micro vibrator. Both the rear and front mold blanks have embedded vibrating housings. Two transmission frames are fixedly connected to the vibrating housings. The first vibrating plate is fixedly connected to the two transmission frames near the rear mold blank, and the second vibrating plate is fixedly connected to the two transmission frames near the front mold blank. The first vibrating plate contacts the second vibrating plate, and a micro vibrator is mounted on the first vibrating plate.

[0007] As an improvement to the above solution, it also includes a cylinder and a striking plate. The cylinder is installed inside the base plate, and the striking plate is fixedly connected to the telescopic rod of the cylinder. The striking plate contacts the template.

[0008] As an improvement to the above solution, it also includes a temperature conduction ring, a liquid delivery pipe, a water pump, and a liquid collection tank. Two temperature conduction rings are fixedly connected to the vibrating housing. Both temperature conduction rings located on the same vibrating housing are connected to the liquid collection tank via liquid delivery pipes, and a water pump is installed on one of the liquid delivery pipes.

[0009] As an improvement to the above scheme, heat exchange tubes are also included, with heat exchange tubes connecting both the template and the two liquid delivery pipes.

[0010] As an improvement to the above solution, a lid is also included, with the collection tank covered by a lid.

[0011] As an improvement to the above scheme, the heat exchange tube is a flexible tube.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By activating the micro vibrator, the micro vibrator generates vibration and transmits the vibration to the first vibration plate and the second vibration plate, and then transmits it to the transmission frame and the vibration housing through the first vibration plate and the second vibration plate. Finally, the vibration housing transmits the vibration to the rear mold blank and the front mold blank, thereby reducing the adhesion of the casting to the rear mold blank and the front mold blank, thus making it easier to remove the casting from the mold blank.

[0013] 2. By activating the cylinder, the extension and retraction of the cylinder rod causes the striking plate to move upward, so that the striking plate lightly strikes the template. The resulting vibration helps to release the stress in the raw material, promotes more uniform shrinkage of the casting, and reduces warping or cracking caused by internal stress.

[0014] 3. By starting the water pump, the water pump draws water from the collection tank, which then enters the two vibrating housings through the liquid delivery pipe and flows back to the collection tank through another liquid delivery pipe. This water circulation allows the water to exchange heat with the rear and front mold blanks through the two vibrating housings, thereby accelerating the cooling efficiency of the liquid metal in the rear and front mold blanks.

Detailed Implementation

[0021] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0022] Example 1: A steel casting mold that facilitates demolding, see reference. Figures 1-5 As shown, it includes a base plate 1, a panel 2, a rear mold blank 3, a front mold blank 4, and a template 5. The rear mold blank 3 is welded onto the base plate 1, and the template 5 is embedded in the rear mold blank 3. The front mold blank 4 is covered on the rear mold blank 3, and the panel 2 is welded onto the top of the front mold blank 4. It also includes a first vibrating plate 7, a transmission frame 8, a vibrating housing 9, a second vibrating plate 10, and a micro vibrator 11. The vibrating housing 9 is embedded in both the rear mold blank and the front mold blank 4. The transmission frame 8 is symmetrically fixedly connected to the left side of the vibrating housing 9. The first vibrating plate 7 is fixedly connected to the two transmission frames 8 close to the rear mold blank, and the second vibrating plate 10 is fixedly connected to the two transmission frames 8 close to the front mold blank 4. The first vibrating plate 7 is in contact with the second vibrating plate 10, and the micro vibrator 11 is bolted to the first vibrating plate 7.

[0023] When this device is needed, the raw material is first injected into the rear mold blank 3 and the front mold blank 4 through the injection port, so that the rear mold blank 3, the front mold blank 4 and the template 5 shape the raw material. After the raw material has completely cooled and solidified, the micro vibrator 11 is activated to generate vibration and transmit the vibration to the first vibration plate 7 and the second vibration plate 10. Then, the vibration is transmitted to the transmission frame 8 and the vibration housing 9 through the first vibration plate 7 and the second vibration plate 10. Finally, the vibration housing 9 transmits the vibration to the rear mold blank 3 and the front mold blank 4, thereby reducing the adhesion of the casting to the rear mold blank 3 and the front mold blank 4, so as to facilitate the removal of the casting from the mold blank. Then, the micro vibrator 11 is turned off, the panel 2 and the front mold blank 4 are picked up, and the casting is removed.

[0024] Example 2: Based on Example 1, refer to Figure 2 As shown, it also includes a cylinder 6 and a striking plate 601. The cylinder 6 is installed in the base plate 1, and the striking plate 601 is fixedly connected to the telescopic rod of the cylinder 6. The striking plate 601 is in contact with the template 5 and is located in the rear mold blank 3.

[0025] During cooling and solidification, the cylinder 6 is activated. The extension and retraction of the cylinder 6's telescopic rod causes the striking plate 601 to move upward, so that the striking plate 601 lightly strikes the template 5. The resulting vibration helps to release the stress in the raw material, promotes more uniform shrinkage of the casting, and reduces warping or cracking caused by internal stress. After cooling and solidification, the formed steel casting can be removed.

[0026] See Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, it also includes a temperature conduction ring 12, a liquid delivery pipe 13, a water pump 14, and a liquid collection tank 15. Temperature conduction rings 12 are symmetrically fixedly connected to the front side of the vibrating housing 9. Liquid delivery pipes 13 are connected between the two temperature conduction rings 12 located in the same vibrating housing 9 and the liquid collection tank 15. A water pump 14 is installed on the liquid delivery pipe 13 located at the rear.

[0027] See Figure 1 , Figure 2 and Figure 5 As shown, it also includes heat exchange tubes 17, and heat exchange tubes 17 are connected between template 5 and the two liquid delivery pipes 13.

[0028] See Figure 1 and Figure 4 As shown, it also includes a lid 16, which covers the liquid collection tank 15.

[0029] See Figure 1 , Figure 2 and Figure 5 As shown, heat exchange tube 17 is a flexible tube.

[0030] While the striking plate 601 lightly strikes the template 5, the water pump 14 is activated. The water pump 14 draws water from the liquid collection tank 15, so that the water enters the two vibrating housings 9 through the liquid delivery pipe 13 and flows back to the liquid collection tank 15 through another liquid delivery pipe 13. This water circulation allows heat exchange between the two vibrating housings 9 and the rear mold blank 3 and the front mold blank 4, thereby accelerating the cooling efficiency of the liquid metal in the rear mold blank 3 and the front mold blank 4. The water can also be delivered to the template 5 through the heat exchange pipe 17 to ensure uniform cooling of the liquid metal. The cover 16 on the liquid collection tank 15 can prevent debris from falling into the liquid collection tank 15.
