[0038] According to the utility model, a double-working head multi-station coordinated casting machine is provided. Figure 1-Figure 2 ,include:

[0039] An installation bracket 100, wherein a plurality of workstations are arranged around the installation bracket 100;

[0040] At least two working heads 200, a plurality of the working heads 200 are stacked in sequence and are rotatably connected to the mounting bracket 100 through swing arms 210 respectively;

[0041] There are at least two driving mechanisms 300, each of which is connected to each of the working heads 200, and is used to drive the working heads 200 to swing around the mounting bracket 100;

[0042] In the direction along which the working heads 200 are arranged in sequence, there is a gap between every two adjacent working heads 200 .

[0043] Specifically, the operator first operates a working head 200 to rotate to the processing station and then pours raw materials into the working head 200. The raw materials are cooled and shaped inside the working head 200 to form a cast workpiece. After the cast workpiece is taken out, the working head 200 is operated to rotate a preset angle to reach the cleaning station to clean the mold or replace the mold, and at the same time, another working head 200 is driven to rotate to the processing station for casting.

[0044] Since the above-mentioned working heads 200 operate independently, when one of the working heads 200 needs to clean the mold or replace the mold, the entire production line does not need to stop product output. The other working head 200 can still be rotated to the processing station to perform casting work, so that the casting work can be carried out uninterruptedly, greatly improving production efficiency.

[0045] The above-mentioned work head 200 is a casting work head structure commonly used in the prior art, and the basic operations include: 1. The casting work head 200 closes the mold and turns to the casting station to pour raw materials into the casting work head 200; 2. The casting work head 200 cools down at the casting station and shapes the casting workpiece; 3. After cooling to a preset time, the casting work head 200 turns to the automatic output device station to open the mold and automatically eject the casting workpiece; 4. The casting work head 200 turns to the manual operation station to complete mold cleaning, water immersion cooling, and manual placement of sand cores.

[0046] In this embodiment, by utilizing the rapid rotation of the two working heads 200 , one person can operate the two working heads 200 at the same time, which can significantly improve production efficiency.

[0047] Since multiple workstations are linked and the two work heads 200 do not interfere with each other, the time gaps between the action rhythms of the work heads 200 can be fully utilized to complement each other, shorten the bottleneck time of the process route, and greatly improve production efficiency.

[0048] The present application improves operational efficiency while also improving convenience. The two working heads 200 are integrated into one device to reduce the difficulty of maintenance. There is a gap between each two adjacent working heads 200 and they will not collide with each other, which can ensure the safety of the equipment and the operator.

[0049] At the same time, the present application adopts a multi-station process surrounding layout in the lean production concept, and multiple working heads 200 are stacked in sequence and arranged in a vertical space, which reduces the floor space on the plane and increases the output value within the unit space of the factory.

[0050] like Figure 2 In some embodiments, the mounting bracket 100 is vertically arranged, and the plurality of working heads 200 are spaced apart in the height direction of the mounting bracket 100, and the planes where the rotation trajectories of the working heads 200 are located are parallel to the horizontal plane.

[0051] Specifically, since the multiple work heads 200 are spaced apart in the height direction along the mounting bracket 100, the multiple work heads 200 are vertically stacked up and down in the vertical space, which greatly reduces the plane footprint; the processing operations of each work head 200 are at different heights, and adjacent work heads 200 cannot interfere with each other during horizontal rotation, which can ensure the safety of the equipment and the operator.

[0052] like Figure 2In some embodiments, one end of the swing arm 210 is connected to the working head 200, and the other end is provided with a mounting ring 211, and the mounting ring 211 is rotatably fixed to the mounting bracket 100 through a slewing bearing a. The mounting ring 211 is rotatably fixed to the mounting bracket 100 through a slewing bearing a, so that the swing arm 210 can rotate around the mounting bracket 100.

[0053] like Figure 2 In some embodiments, a slewing bearing a is sandwiched between the mounting rings 211 of the two upper and lower adjacent swing arms 210, and the inner ring and the outer ring of the slewing bearing a are respectively fixedly connected to the mounting rings 211 of the two upper and lower adjacent swing arms 210. Through the slewing bearing a between the mounting rings 211 of the two swing arms 210, the upper and lower swing arms 210 can swing independently without affecting each other, ensuring that each working head 200 can rotate independently and freely.

[0054] like Figure 3 In some embodiments, the driving mechanism 300 includes:

[0055] A gear ring 310, wherein the gear ring 310 is embedded in the mounting ring 211 of the swing arm 210, and an outer ring of the gear ring 310 is interference fit with an inner ring of the mounting ring 211;

[0056] A driving motor 320 , wherein a driving gear 321 at a front end of the driving motor 320 is meshed with the inner teeth of the ring gear 310 , and is used to drive the ring gear 310 to rotate.

[0057] Specifically, taking the rotation of a working head 200 as an example, when the driving motor 320 is started, the driving gear 321 at the front end rotates by meshing with the driving ring gear 310, thereby driving the working head 200 to rotate. Since the above-mentioned working heads 200 operate independently, when one of the working heads 200 completes casting and rotates to the cleaning station to clean the mold or replace the mold, the entire production line will not stop, and the other working head 200 can be rotated to the processing station to perform casting work at the same time, so that the casting work can be carried out uninterruptedly, greatly improving production efficiency.

[0058] like Figure 1 In some embodiments, an automatic conveying device 400 is further included. There are multiple automatic conveying devices 400 distributed around the periphery of the mounting bracket 100, and each automatic conveying device 400 is respectively connected to each working head 200 to output the casting workpiece processed by the working head 200.

[0059] Specifically, the casting workpiece taken out from the working head 200 can be output to the next process through the automatic conveying device 400, thereby improving the automation level of the operation and the overall production efficiency.

[0060] like Figure 2 , in some embodiments, further comprising:

[0061] A rotating mechanism 500 is provided between the swing arm 210 and the working head 200 and is used to drive the working head 200 to rotate relative to the swing arm 210;

[0062] The sliding mechanism 600 is disposed between the swing arm 210 and the working head 200 , and is used to drive the working head 200 to slide relative to the swing arm 210 .

[0063] Specifically, during operation, raw materials are poured into the casting work head 200 and the mold is closed; the rotary mechanism 500, such as a rotary motor, drives the work head 200 to rotate and tilt to cool and lower the temperature, and the cast workpiece is formed; after cooling to a preset time, the rotary mechanism 500 drives the work head 200 to rotate in the opposite direction to a horizontal position to open the mold and manually take out the cast workpiece. The tilted state is conducive to the flow of the casting raw materials in the working head 200 and rapid cooling.

[0064] In some casting processes, a sliding mechanism 600 such as a slide rail is required to drive the working head 200 to slide back and forth relative to the swing arm 210 during the cooling process, which can accelerate the mixing of the internal casting raw materials to achieve the purpose of homogenization and keep the performance of each part of the final casting workpiece consistent.

[0065] The exemplary implementation scheme proposed in the present invention is described in detail above with reference to the preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the present invention, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present invention can be combined in various ways without exceeding the protection scope of the present invention, which is determined by the attached claims.
