Technical Field

[0001] The utility model belongs to the technical field of low-pressure casting machines, and particularly relates to a furnace body moving device that can be used for low-pressure casting. Background Art

[0002] A low-pressure casting machine is an advanced casting device in the casting technology field.

[0021] As Figures 1-3 shown, a furnace body moving device applicable to low-pressure casting is arranged below the press main body 1, and includes a chassis 2, several groups of lifting mechanisms 3, a moving assembly 4, a moving chassis 5, a furnace body 6, and several furnace body supports 7. The chassis 2 is located directly below the press main body 1, and several lifting mechanisms 3 are evenly arranged between the press main body 1 and the chassis 2. The lifting end of the lifting mechanism 3 is connected to the press main body 1, and the fixed end of the lifting mechanism 3 is fixedly connected to the chassis 2. The moving assembly 4 is installed below the press main body 1. The moving chassis 5 is drivingly connected to the moving assembly 4 and moves along the track of the moving assembly 4. Several furnace body supports 7 are distributed and installed on the moving chassis 5 to form a furnace body placement space for placing the furnace body 6.

[0022] In this Embodiment 1, preferably 4 lifting mechanisms are provided, which are evenly distributed at the four corners of the chassis to stably drive the press main body 1 to move up and down. The lifting mechanism in the present utility model can be, but is not limited to, a hydraulic lifting mechanism, a lifting cylinder, or an electric lifting device, and any existing device capable of realizing lifting drive can be applicable.

[0023] In this Embodiment 1, preferably 4 furnace body supports 7 are provided, which are evenly distributed at the four corners of the moving chassis 5 to stably support the furnace body.

[0024] In this Embodiment 1, the moving assembly 4 includes several guide rails 4-1, a telescopic driving device 4-2, and a mounting support 4-3. The several guide rails 4-1 are arranged in parallel on the mounting frame 4-4. The telescopic driving device 4-2 is fixedly installed on the mounting frame 4-4 through the mounting support 4-3, and the driving end of the telescopic driving device 4-2 is drivingly connected to the moving chassis 5. The telescopic direction of the telescopic driving device 4-2 is parallel to the guide rails 4-1.

[0025] In this Embodiment 1, preferably 2 guide rails 4-1 are provided; the telescopic driving device 4-2 can be, but is not limited to, a telescopic device such as an oil cylinder driving device or a telescopic cylinder, and any existing device capable of realizing telescopic drive can be applicable.

[0026] In this Embodiment 1, the bottom of the moving chassis 5 is slidably installed on the guide rails 4-1 of the moving assembly 4 through rolling wheels 5-1, and the front end of the moving chassis 5 is connected to the driving end of the telescopic driving device 4-2.

[0027] In the first embodiment, several furnace body supports 7 are distributively installed on the moving chassis 5, and the support blocks 7-1 of the furnace body supports 7 are in close contact with the wall surface of the furnace body 6.

[0028] To further ensure the close contact between the support block 7 and the furnace body 6, an arc-shaped contact surface 7-11 matching the outer wall surface of the furnace body 6 is provided on the side surface of the support block in the first embodiment, which is used to closely contact the outer wall surface of the furnace body 6.

[0029] To further ensure the connection sealing performance between the furnace body and the press main body, as Figure 4 shown, the specific structure of the furnace body support 7 is as follows: it includes a support guide post 7-2, a support guide sleeve 7-3, a support spring 7-4, and a support block 7-1. The support guide post 7-2 is vertically and fixedly installed on the moving chassis 5. The support guide sleeve 7-3 is installed on the support guide post 7-2.

[0030] The working principle of the present utility model is as follows:

[0031] When it is necessary to move the furnace body for feeding, first control the lifting mechanism 3 to work, driving the entire press main body 1 to move upward, so that the connection between the press main body 1 and the furnace body 6 is disengaged. Subsequently, control the telescopic driving device 4-2 to perform an extending movement, thereby driving the moving chassis 5 and the furnace body 6 installed on the moving chassis 5 to move outward along the guide rail 4-1 until the furnace body 6 reaches the preset feeding position, as Figure 2 shown.

[0032] When the furnace body needs to return to its original position for low-pressure casting after feeding, first control the telescopic driving device 4-2 to perform a contracting movement, thereby driving the moving chassis 5 and the furnace body 6 installed on the moving chassis 5 to move in the direction of the press main body 1 along the guide rail 4-1 until the furnace body 6 returns to the working position. Subsequently, control the lifting mechanism 3 to work, driving the entire press main body 1 to move downward, so that the press main body 1 is docked with the furnace body 6. During this docking process, the downward movement of the press main body 1 will generate a downward force on the furnace body 6. At this time, under the action of the support spring 7-4, an upward force is generated through the support block 7-1, thereby ensuring the close docking between the furnace body and the press main body and improving the docking sealing performance.

[0033] The above description is only an illustration of the present utility model and is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the premise of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
