[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0020] In the process of using traditional casting molds, after the top mold and bottom mold are closed, molten metal is poured into the mold through the casting gate. After the molten metal cools into a workpiece, the workpiece is demolded. In actual operation, the number of casting stations is fixed and cannot be increased or decreased appropriately. Moreover, when there are too many stations, it will also lead to inconvenience in transportation and transfer, which in turn brings inconvenience to the staff.

[0021] In view of this, the present invention provides a multi-station casting mold for forming metal workpieces. The inner mold is fixed inside the first bottom mold and the second bottom mold, and multiple limiting rods restrict the movement of the top mold, which facilitates the closing of the first bottom mold and the second bottom mold. The first bottom mold and the second bottom mold are connected together by a connecting mechanism. After the molds are connected to each other, the overall structure is more stable and can better withstand the pressure of molten metal or other casting materials during the casting process, reducing the risk of mold deformation or damage. At the same time, the casting stations can be added or reduced according to actual operation needs to improve the convenience of use.

[0022] Example 1: By Figure 1 , 2As shown in sections 3 and 4, a multi-station casting mold for forming metal workpieces includes a first bottom mold 1 and a second bottom mold 12. Inner molds 8 are respectively inserted into the inner walls of the first bottom mold 1 and the second bottom mold 12. Multiple limiting rods 7 are respectively fixedly connected to the tops of the first bottom mold 1 and the second bottom mold 12. A top mold 4 is sleeved on the outer walls of the multiple limiting rods 7. The outer wall of the top mold 4 abuts against the inner mold 8 near the side of the first bottom mold 1 and the outer wall of the first bottom mold 1. A connecting mechanism 2 is provided on the outer walls of the first bottom mold 1 and the second bottom mold 12. The connecting mechanism 2 includes: multiple connecting grooves 21, respectively machined on the outer walls of the first bottom mold 1 and the second bottom mold 12; multiple insert plates 22, respectively fixedly connected to the side of the outer walls of the first bottom mold 1 and the second bottom mold 12 near the connecting grooves 21; and multiple connecting plates 23. Two threaded rods 24 are respectively fixedly connected to the outer walls of the first bottom mold 1 and the second bottom mold 12 on the side away from the connecting groove 21. The inner walls of the two connecting plates 23 near the first bottom mold 1 are in contact with the outer wall of the second bottom mold 12, and the inner walls of the two connecting plates 23 near the first bottom mold 1 are sleeved with the outer walls of the two insert plates 22 near the second bottom mold 12. Two threaded rods 24 are provided, each threadedly connected to the inner walls of the two connecting plates 23 near the first bottom mold 1 and each inserting into the inner walls of the two insert plates 22 near the second bottom mold 12. The two connecting plates 23 near the first bottom mold 1 are sleeved onto the outer walls of the two insert plates 22 near the second bottom mold 12. By twisting the two threaded rods 24, the first bottom mold 1 and the second bottom mold 12 are fixed together through the insertion plates 22 and the connecting plates 23.

[0023] In the specific implementation process, it is worth noting that the first bottom mold 1 and the second bottom mold 12 are fixed to the inner mold 8 by fixing rods, and multiple limiting rods 7 restrict the movement of the top mold 4, which facilitates the mold closing between the top mold 4 and the first bottom mold 1. The connecting groove 21 is processed into a sloping structure to push the first bottom mold 1 to move. The two connecting plates 23 on the side near the first bottom mold 1 are sleeved onto the outer walls of the two insert plates 22 on the side near the second bottom mold 12. The two threaded rods 24 are twisted to fix the first bottom mold 1 and the second bottom mold 12 together through the insert plates 22 and the connecting plates 23.

[0024] Furthermore, the inner wall of the top mold 4 is machined with two vent holes 5, and the top of the top mold 4 is connected to a casting port 6;

[0025] In the specific implementation process, it is worth noting that the vent 5 facilitates the outward discharge of air from inside the mold, and the pouring port 6 facilitates the entry of molten liquid into the mold.

[0026] Furthermore, cooling grooves 9 are respectively machined on the inner walls of the first bottom mold 1 and the second bottom mold 12. Multiple connecting pipes 10 are fixedly connected to the top of the two cooling grooves 9. The outer walls of the multiple connecting pipes 10 are fixedly connected to the inner walls of the first bottom mold 1 and the second bottom mold 12. The interior of the multiple connecting pipes 10 is connected to the interior of the two cooling grooves 9.

[0027] In the specific implementation process, it is worth noting that the connecting pipe 10 introduces cooling water into the cooling tank 9;

[0028] Furthermore, two bends 11 are fixedly connected to the top of the multiple connecting pipes 10, and the interiors of the two bends 11 are connected to the interiors of the multiple connecting pipes 10.

[0029] In the specific implementation process, it is worth noting that the two bends 11 are fixed to the connecting pipe 10 through the flange, and the two bends 11 connect the cooling tank 9 inside the first bottom mold 1 and the cooling tank 9 inside the second bottom mold 12 together.

[0030] Specifically, when using this multi-station casting mold for metal workpiece forming, the inner mold 8 is installed inside the first bottom mold 1 and the second bottom mold 12. Multiple limiting rods 7 fix the top mold 4 above the first bottom mold 1 and the second bottom mold 12, pushing the first bottom mold 1 towards the second bottom mold 12. Two connecting plates 23 near the first bottom mold 1 are fitted onto the outer walls of two insert plates 22 near the second bottom mold 12. The operator twists two threaded rods 24, using the insert plates 22 in conjunction with the connecting plates 23, to fix the first bottom mold 1 and the second bottom mold 12 together, thus completing the fixation between them. After the first bottom mold 1 and the second bottom mold 12 are fixed together, the stability is good, and problems are less likely to occur. To address the deformation issue, molten metal is poured into the first bottom mold 1 and the second bottom mold 12 through two casting ports 6. Two bent pipes 11 connect the cooling tanks 9 inside the first bottom mold 1 and the second bottom mold 12 through multiple connecting pipes 10. The pipes above the first bottom mold 1 and the second bottom mold 12 are connected to the inlet pipe and the outlet pipe, respectively. External cooling water enters the connecting pipe 10 inside the first bottom mold 1 through the pipes. The water inside the connecting pipe 10 enters the cooling tank 9 inside the first bottom mold 1. The cooling water inside the cooling tank 9 inside the first bottom mold 1 flows into the cooling tank 9 inside the second bottom mold 12 through the bent pipes 11. The cooling water is used to cool the interior of the first bottom mold 1 and the second bottom mold 12.

[0031] Example 2: From Figure 1 and 4It is known that the bottom of the first bottom mold 1 and the second bottom mold 12 are provided with a demolding mechanism 3. The demolding mechanism 3 includes: two vertical rods 31, which are fixedly connected to the bottom of the first bottom mold 1 and the second bottom mold 12 respectively; two rotating plates 32, which are rotatably connected to the back of the two vertical rods 31 respectively; two sliders 33, which are fixedly connected to the back of the two rotating plates 32 respectively; two sliding grooves 34, which are movably engaged with the outer wall of the two sliders 33 and fit against the top of the two rotating plates 32 respectively; multiple round rods 35, which are fixedly connected to the top of the two sliding grooves 34 respectively and inserted into the inner wall of the first bottom mold 1 and the second bottom mold 12 respectively; and two push plates 36, which are fixedly connected to the front of the two rotating plates 32 respectively. Among them, the push plate 36 drives the rotating plate 32 to rotate around the bottom of the vertical rods 31, the rotating plate 32 drives the sliding groove 34 to move upward through the sliders 33, and the sliding groove 34 drives the round rods 35 to move upward, thereby completing the demolding of the workpiece inside the first bottom mold 1 and the second bottom mold 12.

[0032] In the specific implementation process, it is worth noting that the top of the rotating plate 32 is attached to the bottom of the slide groove 34 to prevent the slide groove 34 from continuing to move downward. The push plate 36 drives the rotating plate 32 to rotate around the bottom of the vertical rod 31. The rotating plate 32 drives the slide groove 34 to move upward through the slider 33. The slide groove 34 drives the round rod 35 to move upward.

[0033] Specifically, based on the above embodiment 1, when it is necessary to demold the first bottom mold 1 and the second bottom mold 12, the worker pushes the push plate 36 to drive the rotating plate 32 to rotate around the bottom of the vertical rod 31. The rotating plate 32 drives the sliding groove 34 to move upward through the slider 33. The sliding groove 34 drives the round rod 35 to move upward, completing the demolding of the workpiece inside the first bottom mold 1 and the second bottom mold 12. After demolding, the rotating plate 32 is pushed to drive the round rod 35 to reset, making it convenient for the next use.
