[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the casting mold for processing planetary flange castings adopts a new structural design, so that when the device is working, the lower mold can be cooled through the main heat sink, the auxiliary heat sink and the cooling water pipe, shortening the cooling time. At the same time, after the device is formed, when the upper mold is removed, the knocking rod and the push rod work, which plays a role in assisting the material unloading, facilitating the operation of the staff and improving the work efficiency. The specific contents are as follows: The casting mold for processing planetary flange castings, when in use, pours the molten metal into the lower mold, covers the upper mold and waits for molding, and after molding, removes the upper mold, at this time, the upper mold drives the long pin to rotate through the rack and gear, and then the movable plate drives the knocking rod to make reciprocating linear motion in the horizontal direction, the knocking rod will hit the outer wall of the lower mold again and again, so that the lower mold vibrates, plays a role in assisting material removal, facilitates the operator to take out the workpiece, and improves work efficiency; Furthermore, when installing the upper die, the positioning rod on the lower surface of the upper die is inserted into the positioning tube on the upper surface of the working plate. At this time, the force-bearing rod is squeezed, and the force-bearing rod drives the push rod to move in the direction of squeezing the first spring. When removing the upper die, the force-bearing rod and the push rod lose pressure. At this time, the push rod rises under the action of the first spring, and then the push rod plays a role in pushing the workpiece, and also plays a role in assisting material unloading, thereby optimizing the effect of assisting material unloading; Furthermore, when the push rod is not working, the through hole is located inside the lower die, and when the push rod rises, the through hole rises synchronously, and at the same time, the push rod drives the extrusion plate and the airbag to rise through the external rod, and then the airbag will be squeezed by the extrusion plate and the inner wall of the lower die, and then the airbag will be exhausted through the No. 1 pipe, and the lower die is a sealed structure, so the airflow can only be blown out from the through hole inside the push rod. At this time, the airflow plays a role of auxiliary pushing, and also plays a role of separating the workpiece and the inner wall of the lower die, which is convenient for demoulding of the formed workpiece; The casting mold for processing the planetary flange casting starts the water pump on the upper surface of the working plate during the workpiece forming process. At this time, the coolant flows through the cooling water pipe and the connecting pipe, and then the cooling water pipe plays an auxiliary cooling role, which is convenient for the forming work of the workpiece. The coolant is also in a shaking state inside the cooling box, which is convenient for the heat dissipation of the coolant itself. Furthermore, during the molding process, the main heat sink and the auxiliary heat sink absorb the heat inside the lower mold and discharge the heat into the air. The main heat sink and the auxiliary heat sink play a role of auxiliary cooling, thereby optimizing the effect of auxiliary cooling. (3) In the casting mold for processing the planetary flange casting, when the water pump is working, the coolant enters the cooling box through the connecting pipe. In this process, the water wheel and the connecting shaft will rotate under the impact force of the coolant. When the connecting shaft rotates, it will drive the cam to rotate synchronously. When the cam rotates, it will intermittently contact the main heat sink. Then, the main heat sink and the auxiliary heat sink make reciprocating linear motion in the horizontal direction under the action of the cam, the limit column and the return spring. Then, the main heat sink and the auxiliary heat sink can contact with more air, so that the heat dissipation effect is better, which can accelerate the forming of the workpiece and improve the work efficiency.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1: By setting the push rod 5, the push rod 5 can assist in unloading when the lower mold 2 is unloading, so that the staff can take the molded workpiece easily. Figure 1-Figure 4 As shown: A casting mold for processing planetary flange castings, comprising a working plate 1 and a cooling water pipe 7, wherein a lower mold 2 is fixedly connected to the upper surface of the working plate 1, an upper mold 3 is movably arranged on the upper surface of the lower mold 2, a force rod 4 is slidably arranged inside the lower mold 2, and a push rod 5 is slidably arranged inside the lower mold 2, and the cooling water pipe 7 is fixedly connected to the inside of the lower mold 2; Also includes: A positioning rod 9, the positioning rod 9 is fixedly connected to the lower surface of the upper mold 3, and the lower surface of the upper mold 3 is fixedly connected with a rack 10, a long pin 11, and the long pin 11 is rotatably arranged on the outer wall of the lower mold 2, a cross bar 16, the cross bar 16 is fixedly connected to the outer wall of the lower mold 2, and the surface of the cross bar 16 is sleeved and connected with a movable plate 14, and the surface of the movable plate 14 is fixedly connected with a knocking rod 17; A cooling box 20, the cooling box 20 is bolted to the upper surface of the working plate 1, and a connecting shaft 21 is rotatably provided inside the cooling box 20, and a water wheel 23 and a water pump 22 are fixedly connected to the surface of the connecting shaft 21, the water pump 22 is bolted to the upper surface of the working plate 1, and the output end of the water pump 22 can be connected to the end of the cooling water pipe 7 through a threaded connection external hose; A connecting pipe 25, the connecting pipe 25 is fixedly connected to the inside of the cooling box 20, and the connecting pipe 25 can be connected to the end of the cooling water pipe 7 through a threaded connection external hose, a limiting rod 28, the limiting rod 28 is fixedly connected to the inner wall of the lower mold 2, and the surface of the limiting rod 28 is sleeved with a main heat sink 24, and the surface of the main heat sink 24 is fixedly connected with auxiliary heat sinks 26 at equal intervals; The airbag 30 has an extrusion plate 31 bonded to its lower surface, and the upper surface of the extrusion plate 31 is convex, and both left and right sides of the extrusion plate 31 are fixedly connected with an external rod 32, and the end of the external rod 32 is fixedly connected to the surface of the push rod 5.

[0020] A positioning tube 8 is fixedly connected to the upper surface of the working plate 1, and the positioning tube 8 is symmetrically distributed about the center of the working plate 1, and the positioning tube 8 corresponds one-to-one with the positioning rod 9. The surface of the force-bearing rod 4 is convex, and the end of the force-bearing rod 4 is fixedly connected to the surface of the push rod 5.

[0021] The lower surface of the push rod 5 is fixedly connected with a first spring 6 which plays an elastic reset role, and the other side of the first spring 6 is fixedly connected to the inner wall of the lower mold 2. The left and right sides of the airbag 30 are fixedly connected with a No. 1 tube 33.

[0022] After pouring the molten metal into the lower mold 2, the upper mold 3 is covered. When installing the upper mold 3, the positioning rod 9 on the lower surface of the upper mold 3 is inserted into the positioning tube 8 on the upper surface of the working plate 1. At this time, the force rod 4 is squeezed, and the force rod 4 drives the push rod 5 to move in the direction of squeezing the first spring 6. After molding, when the staff removes the upper mold 3, the force rod 4 and the push rod 5 lose pressure. At this time, the push rod 5 rises under the action of the first spring 6, and then the push rod 5 plays a role in pushing the workpiece, that is, the push rod 5 plays a role in assisting the unloading of the material, so that the staff can more conveniently remove the molded workpiece.

[0023] Embodiment 2: Different from Embodiment 1, a through hole 36 is provided on the surface of the push rod 5, so that the air inside the airbag 30 can be discharged into the lower mold 2 through the through hole 36. At this time, the flowing airflow plays a role in assisting the separation of the molded workpiece and the inner wall of the lower mold 2. Figure 4 and Figure 5 as well as Fig.12 As shown: A No. 2 pipe 34 is fixedly connected to the lower surface of the airbag 30, and a one-way valve 35 is fixedly connected to the surface of the No. 2 pipe 34 and the surface of the No. 1 pipe 33, and the lower surface of the No. 2 pipe 34 is located inside the working plate 1, a through hole is opened on the surface of the working plate 1, and a through hole 36 is opened inside the push rod 5.

[0024] When the push rod 5 is not working, the through hole 36 is located inside the lower mold 2, and when the push rod 5 rises, the through hole 36 rises synchronously, and at the same time, the push rod 5 drives the extrusion plate 31 and the airbag 30 to rise through the external rod 32, and then the airbag 30 will be squeezed by the extrusion plate 31 and the inner wall of the lower mold 2, and then the airbag 30 will be exhausted through the No. 1 pipe 33, and the lower mold 2 is a sealed structure, so the airflow can only be blown out from the through hole 36 inside the push rod 5. At this time, the airflow plays a role of auxiliary pushing, and also plays a role in separating the workpiece and the inner wall of the lower mold 2. It is convenient for demoulding the formed workpiece. During the next forming process, when the upper mold 3 is covered again, the push rod 5, the external rod 32 and the extrusion plate 31 descend. At this time, the airbag 30 expands again, and then the airbag 30 sucks the outside air into the airbag 30 through the No. 2 pipe 34. When the airbag 30 is working, the one-way valve 35 makes the air flow direction from the No. 2 pipe 34 to the airbag 30, and then from the airbag 30 to the No. 1 pipe 33. Backflow will not occur, thus ensuring stability. The through holes on the surface of the working plate 1 facilitate the air intake work of the No. 2 pipe 34.

[0025] Embodiment 3: Different from Embodiment 2, the knocking rod 17 is provided to make the lower mold 2 vibrate slightly when unloading, so as to prevent the molded workpiece from being bonded to the lower mold 2. Figure 6-Figure 8 As shown: The surface of the long pin 11 is fixedly connected to a gear 12 meshing with the rack 10, and the surface of the long pin 11 is fixedly connected to a disc 13, and the surface of the disc 13 and the surface of the movable plate 14 are fixedly connected to magnets 15, the magnets 15 are distributed at equal angles on the surface of the disc 13, and the adjacent poles of adjacent magnets 15 are opposite, and the end of the cross bar 16 is fixedly connected to a baffle 19.

[0026] A second spring 18 that plays an elastic reset role is fixedly connected to the surface of the baffle 19, and the other side of the second spring 18 is fixedly connected to the outer wall of the movable plate 14. The knocking rods 17 are evenly spaced on the surface of the movable plate 14. The connecting shaft 21 passes through the interior of the cooling box 20, and a cam 27 is fixedly connected to the surface of the connecting shaft 21.

[0027] After the workpiece is formed, when the upper die 3 is removed, the upper die 3 drives the long pin 11 to rotate on the surface of the lower die 2 through the rack 10 on the lower surface and the gear 12 on the surface of the long pin 11, and then the long pin 11 drives the disc 13 to rotate synchronously, that is, the magnet 15 on the surface of the disc 13 will intermittently approach the magnet 15 on the surface of the movable plate 14. When the magnet 15 on the surface of the disc 13 approaches the magnet 15 on the surface of the movable plate 14, the movable plate 14 moves in the direction of squeezing the second spring 18 under the action of the mutual magnetic force, and the magnet 15 on the surface of the disc 13 continues to move. When the movable plate 14 continues to rotate and moves away from the magnet 15 on the surface of the movable plate 14, the movable plate 14 moves back under the action of the second spring 18 and the baffle 19, and the above process is repeated. The movable plate 14 drives the knocking rod 17 to make reciprocating linear motion in the horizontal direction (the cross bar 16 makes the movable plate 14 move only in the horizontal direction), and then the knocking rod 17 will hit the outer wall of the lower mold 2 again and again, causing the lower mold 2 to vibrate, playing a role in assisting material unloading. Cooperating with the push rod 5, the effect of assisting material unloading is optimized, which is convenient for the operator to take out the workpiece and improves work efficiency.

[0028] Embodiment 4: Different from Embodiment 3, a cooling structure is provided during the workpiece forming process to accelerate the forming of the workpiece, such as Figure 9-11 As shown: The cam 27 intermittently contacts the main heat sink 24 when rotating, and a reset spring 29 which plays an elastic reset role is fixedly connected to the surface of the main heat sink 24, and the other side of the reset spring 29 is fixedly connected to the inner wall of the lower mold 2, and the surface of the main heat sink 24 and the surface of the auxiliary heat sink 26 are not in contact with the lower mold 2.

[0029] During the workpiece forming process, the water pump 22 on the upper surface of the working plate 1 is started. At this time, the coolant flows through the cooling water pipe 7 and the connecting pipe 25, and then the cooling water pipe 7 can take away the heat inside the lower mold 2, which plays a role of auxiliary cooling and facilitates the forming of the workpiece. The cooling box 20 plays the role of water storage and transition. In this process, the coolant inside the cooling box 20 will be in a shaking state, which is convenient for the heat dissipation of the coolant itself. At the same time, during the workpiece forming process, the main heat sink 24 and the auxiliary heat sink 26 will also absorb the heat of the lower mold 2 and discharge the heat into the air. When the coolant enters the interior of the cooling box 20 through the connecting pipe 25 The coolant will impact the water wheel 23, causing the water wheel 23 and the connecting shaft 21 to rotate. When the connecting shaft 21 rotates, the cam 27 is driven to rotate synchronously. When the cam 27 rotates to push the main heat sink 24, the main heat sink 24 will slide on the limit rod 28. At this time, the return spring 29 is squeezed, and when the cam 27 continues to rotate until it is no longer in contact with the main heat sink 24, the main heat sink 24 moves back under the action of the return spring 29, and the above process is repeated. The main heat sink 24 and the auxiliary heat sink 26 make reciprocating linear motion in the horizontal direction, and then the main heat sink 24 and the auxiliary heat sink 26 will contact with more air, thereby optimizing the heat dissipation effect and improving work efficiency.

[0030] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
