[0028] Example

[0029] Reference Figures 1-3 This embodiment provides a mold changing device for casting molds, including a casting machine base 100, a guide rail assembly 200, and a mold changing carriage 300; one section of the guide rail assembly 200 is detachably connected to the top of the casting machine base 100, and the other section of the guide rail assembly 200 is located on the outside of the casting machine base 100; the mold changing carriage 300 is slidably disposed on the guide rail assembly 200, and the mold changing carriage 300 is used to carry the casting mold 900.

[0030] In this embodiment, when mold changing is required, a section of the guide rail assembly 200 can be temporarily assembled on the casting machine base 100. At this time, the mold changing trolley 300 is located on the section of the guide rail assembly 200 outside the casting machine base 100 and is not limited by the size and structure of the casting machine. Therefore, it is convenient to hoist the casting mold 900 onto the mold changing trolley 300, and then push the mold changing trolley 300 to push the casting mold 900 into the area of ​​the casting machine base 100 for mold changing operation. After the mold changing is completed, the guide rail assembly 200 can be removed from the casting machine base 100. The operation is convenient and quick. Therefore, mold changing can be completed from both the front and side of the casting machine, which can meet the mold changing requirements when the length or width dimension exceeds the limit, thereby reducing the difficulty of mold changing operation and improving work efficiency.

[0031] It should be noted that the guide rail assembly 200 can be detachably connected to the casting machine base 100 via fasteners such as bolts and pins, which facilitates assembly and disassembly.

[0032] As an optional implementation, the mold changing carriage 300 includes a support platform 310 and a plurality of guide rollers 320. The plurality of guide rollers 320 are connected to the bottom of the support platform 310 and slide in cooperation with the guide rail assembly 200.

[0033] In this embodiment, after the casting mold 900 is hoisted onto the support platform 310, the support platform 310 and the casting mold 900 can be easily moved to the casting machine platform 100 area by the sliding cooperation of the guide pulley 320 and the guide rail assembly 200, making the operation convenient and quick.

[0034] As an optional implementation, the mold changing vehicle 300 also includes a support plate 330 detachably connected to the top of the support platform 310, and the top surface of the support plate 330 is provided with a first positioning groove 331 that cooperates with the casting mold 900.

[0035] In this embodiment, the casting mold 900 is placed on the support plate 330. The first positioning groove 331 can be positioned and installed with the casting mold 900, which can ensure the installation positioning accuracy when changing the casting mold 900. Here, the support plate 330 can be detachably connected to the support platform 310 by countersunk screws or pins. The support plate 330 with different first positioning groove 331 structures can be replaced according to different types or structures of casting molds 900 for matching installation, without replacing the entire mold changing carriage 300, thus improving the versatility of the mold changing carriage 300.

[0036] As an optional implementation, the support platform 310 is made of steel, and the support plate 330 is made of rubber. The rubber material is wear-resistant, which reduces wear on the support plate 330. At the same time, the rubber material also has a certain degree of elasticity, which can reduce the vibration of the casting mold 900 during the movement of the mold changing carriage 300, making the movement more stable.

[0037] As an alternative implementation, the mold changing cart 300 also includes a handle 340 connected to the side of the support platform 310 away from the casting machine platform 100, which facilitates manual pushing.

[0038] In other embodiments, a drive mechanism, such as a lead screw drive mechanism, can be used to drive the mold changing carriage 300 to move automatically.

[0039] As an optional implementation, hydraulic guide columns 400 are provided at the four corners of the casting machine base 100, and lifting plates 500 are connected to the top of the hydraulic guide columns 400. The lifting plates 500 are detachably connected to the top of the casting mold 900.

[0040] In this embodiment, when mold changing is required, the mold changing carriage 300 moves the casting mold 900 directly below the lifting plate 500. At this time, the lifting plate 500 can be driven to move down along the hydraulic guide column 400 by the hydraulic cylinder (not shown in the figure). The hydraulic guide column 400 plays a stable guiding role. The lifting plate 500 is connected to the top of the casting mold 900 by bolts and other connecting parts. Then, the hydraulic guide column 400 drives the lifting plate 500 and the casting mold 900 to move up as a whole. At this time, the mold changing carriage 300 can slide out of the casting machine base 100 area. Finally, the guide rail assembly 200 is removed from the casting machine base 100 to complete the mold changing operation.

[0041] As an optional implementation, the guide rail assembly 200 includes a guide rail 210 and a support frame 220. One section of the guide rail 210 is detachably connected to the top of the casting machine base 100, and the other section of the guide rail 210 is located on the outside of the casting machine base 100. The support frame 220 is connected to the bottom of the section of the guide rail 210 located on the outside of the casting machine base 100.

[0042] In this embodiment, since the casting machine base 100 generally has a certain height, the guide rail 210 can be designed in sections. One section is used to assemble with the casting machine base 100, and the other section is supported by the support frame 220 to form a certain support height, thereby ensuring the horizontality of the guide rail 210.

[0043] In other embodiments, to improve the versatility of the guide rail assembly 200, the support frame 220 may be of the lifting type, for example, the support frame 220 may be replaced by a hydraulic telescopic cylinder, thereby adjusting the height position of the guide rail 210, so as to match the casting machine base 100 at different height positions.

[0044] As an optional implementation, a connecting plate 600 is connected to a section of the bottom of the guide rail 210 extending into the casting machine base 100. The connecting plate 600 is detachably connected to the top of the casting machine base 100.

[0045] In this embodiment, the guide rail 210 can be connected to the casting machine base 100 via the connecting plate 600, thus avoiding direct connection between the guide rail 210 and the casting machine base 100. This prevents repeated disassembly from damaging the structure of the guide rail 210 and ensures the service life of the guide rail 210. Here, the connecting plate 600 can be detachably connected to the casting machine base 100 via fasteners such as bolts or pins.

[0046] As an optional implementation, the connecting plate 600 is connected to a plurality of positioning plates 700, and the top surface of the casting machine base 100 is provided with a second positioning groove 110 that cooperates with the positioning plates 700.

[0047] In this embodiment, during installation, the connecting plate 600 can be quickly positioned and installed on the top surface of the casting machine base 100 by the snap-fit ​​between the positioning plate 700 and the second positioning groove 110, thereby improving positioning accuracy and assembly efficiency.

[0048] As an optional implementation, the bottom of the support frame 220 is provided with self-locking casters 800 to facilitate the overall movement of the guide rail assembly 200, thereby making it easy to slide the guide rail assembly 200 closer to or out of the casting machine table 100 area.

[0049] It should be noted that when the support frame 220 is not equipped with self-locking casters 800, the guide rail assembly 200 can be moved by hoisting for temporary assembly or removal.

[0050] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
