Description

Technical Field

[0001] The utility model relates to the technical field of water-cooling motor housing casting molds, and more particularly to a water-cooling motor housing casting mold. Background Art

[0002] In current industrial production, water-cooled motor housing casting molds are increasingly used. This mold uses a water cooling system to cool the aluminum alloy melt to ensure the quality and efficiency of housing casting. However, existing technical solutions have some obvious deficiencies in design and function. These deficiencies limit the performance of the mold and have an adverse impact on production efficiency and product quality.

[0003] First of all, although the existing casting mold is equipped with a water cooling function, its water cooling runner design has certain limitations. Specifically, the water cooling runner is usually located on the outside of the molding cavity, which means that the cooling water can only cool the mold from the outside to the inside. This outside-to-inside cooling method has certain disadvantages, which may lead to uneven cooling and affect the molding quality and internal structural strength of the shell.

[0004] Secondly, the water cooling system in the existing technology is usually unable to adjust the input and output speeds of the cooling water, which means that during the casting process, the flow rate of the cooling water is fixed and cannot be flexibly adjusted according to actual usage requirements. This design lacking adjustment capability limits the operator's control over the cooling process, which may lead to unsatisfactory cooling effects, thereby affecting the dimensional accuracy and mechanical properties of the shell.

[0005] In addition, in order to solve the above problems, some equipment attempts to use additional devices to adjust the flow rate of cooling water. However, the structure of these devices is usually relatively simple and the mechanism is not perfect, resulting in low stability of the overall structure. In actual applications, these devices are easily affected by factors such as equipment vibration, resulting in changes in the adjusted flow rate. This unstable phenomenon not only increases the difficulty of operation, but may also cause quality problems in the shell casting process, such as uneven cooling, internal stress concentration, etc., thereby affecting the final performance and service life of the product.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the present invention provides a water-cooled motor housing casting mold, which has the following beneficial effects:

[0019] 1. The design of the heat dissipation device realizes a cooling method from the inside to the outside by installing the water cooling pipe on the inner side of the material core, which greatly improves the cooling efficiency. This design brings the cooling water closer to the melted metal, realizes more sufficient heat exchange, and effectively solves the problem of uneven cooling caused by traditional external cooling methods. The setting of the water inlet and outlet pipes enables the cooling water to circulate continuously, ensuring the continuity and stability of the cooling effect. This internal cooling design not only improves the cooling efficiency, but also helps to improve the internal structural strength and molding quality of the shell.

[0020] 2. The design of the adjustment device, including components such as the control sleeve, connecting pipe, fixed pipe, central tube, circulation groove and slide rod, provides the possibility for precise adjustment of the cooling water flow rate. By rotating the control sleeve, the slide rod can be driven to move in the central tube, thereby changing the number of open circulation grooves and achieving precise control of the cooling water flow rate. This design enables the operator to flexibly adjust the input and output speeds of the cooling water according to actual needs, effectively solving the problem of the inability to adjust the cooling water flow rate in the existing technology. The design of the slide rail and slide groove ensures the accuracy of the slide rod movement and further improves the accuracy of the flow rate adjustment.

[0021] 3. The design of the limiting mechanism provides additional stability and safety for the adjustment device through the combination of the matching sleeve, rotating plate, arc groove, circular groove, limiting rod and limiting plate. The design of the rotating plate and arc groove allows the operator to unlock the adjustment device when needed and lock it again after the adjustment is completed. The setting of the push spring ensures the automatic reset of the locking mechanism, which increases the convenience of operation. The design of the adapter rod and adapter groove further enhances the stability of the control sleeve position and effectively prevents the adjusted flow rate from changing due to factors such as equipment vibration. This multiple locking mechanism not only improves the stability of the adjustment device, but also enhances the reliability and safety of the entire mold system. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] A rubber strip 24 is connected to the outer side of the control cover 7 , and a plurality of rubber strips 24 are fixedly connected to the outer side of the control cover 7 .

[0039] An adapting rod 25 is slidably provided on the side wall of the control sleeve 7 , and a plurality of adapting grooves 26 are opened on the outer side of the fixing tube 9 , and one end of the adapting rod 25 is inserted into the adapting groove 26 .

[0040] A connecting spring 27 is provided on the outside of the control sleeve 7 , and the other end of the adapting rod 25 is connected to the outer wall of the control sleeve 7 via the connecting spring 27 .

[0041] A push spring 28 is sleeved on the outer side of the limiting rod 17 . The push spring 28 is connected to one side of the matching sleeve 13 , and the other side of the push spring 28 is in contact connection with the rotating plate 14 .

[0042] In this embodiment, when the flow rate of the cooling water needs to be adjusted according to demand, the input and output speeds of the cooling water need to be adjusted. First, the rotating plate 14 is rotated, and the rotating plate 14 will drive the arc groove 15 and the circular groove 16 opened on it to rotate. When the position of the circular groove 16 corresponds to the position of the limiting plate 18, the matching sleeve 13 is pushed, and the matching sleeve 13 will drive the limiting rod 17 and the corresponding limiting plate 18 to pass through the circular groove 16. Then the matching sleeve 13 will cooperate with the rotating plate 14 to squeeze the push spring 28. When the push spring 28 is squeezed to the limit, the other limiting plate 18 just passes through the circular groove 16 and reaches the other side of the rotating plate 14. Then the rotating plate 14 is rotated in the opposite direction, and the rotating plate 14 drives the arc groove 15 and the circular groove 16 to rotate. The arc groove 15 and the circular groove 16 move, and then the limiting rod 17 will enter the arc groove 15, and the matching sleeve 13 will be limited to the side of the rotating plate 14 through the cooperation of the limiting rod 17 and the corresponding limiting plate 18. At this time, the outer side of the adapter rod 25 loses the limit of the matching sleeve 13, and then the control sleeve 7 is rotated, and the control sleeve 7 will drive the adapter rod 25 to move. Due to the rounded structure treatment at the end of the adapter rod 25 and the edge of the adapter groove 26, the side wall of the adapter groove 26 squeezes the end of the adapter rod 25, and then one end of the adapter rod 25 will slide out of the adapter groove 26, and the other end of the adapter rod 25 will drive the connecting spring 27 to stretch, and at the same time the control sleeve 7 will drive the screw sleeve through the connecting rod 19. 20 rotates, since the slide rail 22 and the slide groove 23 limit the slide rod 12, the slide rod 12 and the screw 21 will not rotate, and then the screw 21 will drive the slide rod 12 to slide along the slide rail 22 and the slide groove 23 in the middle tube 10, so that the number of blocked flow grooves 11 changes, thereby changing the flow rate of the cooling water. After the flow rate is adjusted appropriately, the connecting spring 27 drives the adapter rod 25 to engage with the corresponding adapter groove 26, and then the rotating plate 14 is rotated again, and the rotating plate 14 drives the yield groove and the circular groove 16 to move. When the circular groove 16 moves to a position concentric with the limiting plate 18, the push spring 28 pushes the matching sleeve 13 to reset, and then The rear mating sleeve 13 drives the limiting rod 17 and the limiting plate 18 to reset. When the push spring 28 is fully reset, the other limiting plate 18 moves back to the side of the rotating plate 14, and then the rotating plate 14 is rotated, so that the arc groove 15 and the circular groove 16 move to a position that does not correspond to the limiting plate 18. Then the limiting plate 18, the limiting rod 17 and the rotating plate 14 cooperate to form a limit on the mating sleeve 13 to prevent the mating sleeve 13 from moving. Then the inner wall of the mating sleeve 13 limits the outer end of the adapter rod 25 to prevent the adapter rod 25 from moving. Then the adapter rod 25 and the adapter groove 26 cooperate to form a stable limit on the control sleeve 7 to prevent the control sleeve 7 from rotating, thereby ensuring the stability after the flow rate is adjusted.

[0043] See also Figure 1-4 As a further embodiment of the entire device: a casting tube 29 is provided on the inner side of the upper mold 2, a casting port 30 is connected to the top end of the casting tube 29, and a casting head 31 is connected to the bottom end of the casting port 30.

[0044] More specifically, when the equipment needs to be used, the upper mold 2 is first driven by an external driving device to drive the material core 3 to descend, prompting the upper mold 2 and the lower mold 1 to be closed, and then the molten metal is poured into the casting port 30, and then the molten metal will enter the casting tube 29, and then reach the casting head 31 through the casting tube 29, and then flow into the middle of the molding cavity of the material core 3 and the lower mold 1 through the casting head 31, and then open the external conveying equipment to convey the cooling water to the water inlet pipe 5 through the connecting pipe 8 and the fixed pipe 9, and then enter the water cooling pipe 4 through the water inlet pipe 5 for circulation. Since the water cooling pipe 4 is arranged on the inner side of the material core 3, the distance between the water cooling pipe 4 and the melted metal is relatively close, and sufficient cooling can be achieved. The cooling water after heat exchange will flow out to the external storage device through the water outlet pipe 6 connected to the other end of the water cooling pipe 4. After cooling it, it can be passed into the water cooling pipe 4 again for recycling.

[0045] In summary, when the overall equipment is in use or running: when the flow rate of the cooling water needs to be adjusted according to demand, the input and output speeds of the cooling water need to be adjusted, first rotate the rotating plate 14, and the rotating plate 14 will drive the arc groove 15 and the circular groove 16 opened on it to rotate. When the position of the circular groove 16 corresponds to the position of the limiting plate 18, push the matching sleeve 13, and the matching sleeve 13 will drive the limiting rod 17 and the corresponding limiting plate 18 to pass through the circular groove 16, and then the matching sleeve 13 will cooperate with the rotating plate 14 to squeeze the push spring 28. When the push spring 28 is squeezed to the limit, the other limiting plate 18 just passes through the circular groove 16 and reaches the other side of the rotating plate 14, and then the rotating plate 14 is rotated in the opposite direction. The plate 14 drives the arc groove 15 and the circular groove 16 to move, and then the limiting rod 17 will enter the arc groove 15, and the matching sleeve 13 will be limited to the side of the rotating plate 14 through the cooperation of the limiting rod 17 and the corresponding limiting plate 18. At this time, the outer side of the adapter rod 25 loses the limit of the matching sleeve 13, and then the control sleeve 7 is rotated, and the control sleeve 7 will drive the adapter rod 25 to move. Due to the rounded structure treatment at the end of the adapter rod 25 and the edge of the adapter groove 26, the side wall of the adapter groove 26 squeezes the end of the adapter rod 25, and then one end of the adapter rod 25 will slide out of the adapter groove 26, and the other end of the adapter rod 25 will drive the connecting spring 27 to stretch, and at the same time the control sleeve 7 will pass through the connecting rod 19 Drive the screw sleeve 20 to rotate. Since the slide rail 22 and the slide groove 23 limit the slide rod 12, the slide rod 12 and the screw rod 21 will not rotate. Then the screw rod 21 will drive the slide rod 12 to slide along the slide rail 22 and the slide groove 23 in the middle tube 10, so that the number of blocked flow grooves 11 changes, thereby changing the flow rate of the cooling water. After the flow rate is adjusted appropriately, the connecting spring 27 drives the adapter rod 25 to engage with the corresponding adapter groove 26, and then the rotating plate 14 is rotated again. The rotating plate 14 drives the yield groove and the circular groove 16 to move. When the circular groove 16 moves to a position concentric with the limiting plate 18, the push spring 28 pushes the matching sleeve 13 to reset. , and then the matching sleeve 13 drives the limiting rod 17 and the limiting plate 18 to reset. When the push spring 28 is completely reset, the other limiting plate 18 moves back to the side of the rotating plate 14, and then the rotating plate 14 is rotated, so that the arc groove 15 and the circular groove 16 move to a position that does not correspond to the limiting plate 18, and then the limiting plate 18, the limiting rod 17 and the rotating plate 14 cooperate to form a limit on the matching sleeve 13 to prevent the matching sleeve 13 from moving, and then the inner wall of the matching sleeve 13 limits the outer end of the adapter rod 25 to prevent the adapter rod 25 from moving, and then the adapter rod 25 and the adapter groove 26 cooperate to form a stable limit on the control sleeve 7 to prevent the control sleeve 7 from rotating, thereby ensuring the stability of the flow rate after adjustment.

[0046] When the equipment needs to be used, the upper mold 2 is first driven by an external driving device to drive the material core 3 to descend, prompting the upper mold 2 and the lower mold 1 to be closed, and then the molten metal is poured into the casting port 30, and then the molten metal will enter the casting tube 29, and then reach the casting head 31 through the casting tube 29, and then flow into the middle of the molding cavity of the material core 3 and the lower mold 1 through the casting head 31, and then open the external conveying equipment to convey the cooling water to the water inlet pipe 5 through the connecting pipe 8 and the fixed pipe 9, and then enter the water cooling pipe 4 through the water inlet pipe 5 for circulation. Since the water cooling pipe 4 is arranged on the inner side of the material core 3, the distance between the water cooling pipe 4 and the melted metal is relatively close, and sufficient cooling can be achieved. The cooling water after heat exchange will flow out to the external storage device through the water outlet pipe 6 connected to the other end of the water cooling pipe 4. After cooling it, it can be passed into the water cooling pipe 4 again for recycling.
