[0001] This utility model relates to the field of water pump manufacturing technology, and more specifically, to a casting device for an automotive water pump housing. Background Technology

[0002] The car water pump is an important component of the car engine cooling system. Its main function is to maintain the engine within the normal operating temperature range by circulating coolant and prevent the engine from overheating. For example, a water pump casting mold casting device is proposed in application number "CN202122260293.5". This solution includes: a base plate, wherein the upper surface of the base plate has a disassembly port, and both sides of the disassembly port have rotating grooves. A rotating column is rotatably connected to the surface of the rotating groove, and a rotating bolt is fixedly connected to one side of the rotating column. A clamping cap is threaded onto the surface of the rotating bolt. A connecting bolt is fixedly connected to the upper surface of the base plate. The outer surface of the top plate has a disassembly port, and the upper surface of the top plate has an insertion hole. The design of the bottom and top plates allows for easy disassembly, enabling quick removal after casting.

The bottom and top molds facilitate the casting of the water pump housing, and the connecting bolts allow for easy insertion of the top plate.

[0003] However, although the above technical solutions can dissipate heat through heat dissipation holes, they still rely on the overall natural heat dissipation for cooling, which makes the overall heat dissipation efficiency still slow. Often, after the raw materials are formed, they need to wait for the whole to cool naturally before they can be taken out and unloaded, resulting in slow overall production efficiency. Therefore, we propose an automotive water pump housing casting device to solve the above problems. Utility Model Content

[0025] like Figures 4 to 7As shown, in another embodiment of this utility model, the auxiliary mechanism 6 includes a first temporary storage slot 601 and a second temporary storage slot 603. The first temporary storage slot 601 is located inside the upper mold 3, and the second temporary storage slot 603 is located inside the lower mold 2. A guide frame 602 is installed through the lower end of the interior of the first temporary storage slot 601, and a guide groove 604 is installed through the upper end of the interior of the second temporary storage slot 603. The lower end of the guide frame 602 is engaged inside the guide groove 604. A water injection pipe 605 is installed through the upper end of the interior of the first temporary storage slot 601, and one end of the water injection pipe 605... Connected to an external water pump, a drain pipe 606 is installed through the lower end of the second temporary storage tank 603. The lower end of the drain pipe 606 is connected to an external water storage tank. A groove 607 is provided in the middle of the support platform 1. The body of the drain pipe 606 is installed through the groove 607. A movable frame 613 is movably installed in the middle of the groove 607. Several push rods 611 are installed on the upper surface of the movable frame 613. The push rods 611 are movably installed between the groove 607 and the lower mold 2. Several sealing grooves 609 are provided on the lower surface of the lower mold 2 for sealing. Guide holes 608 are provided through the lower inner surface of the groove 609. Push rods 611 are movably installed through the guide holes 608. Push plates 610 are fitted inside the sealing groove 609. The upper end of the push rod 611 is connected to the push plate 610. Springs 612 are sleeved on the outer side of the push rod 611 located between the groove 607 and the movable frame 613. A transmission plate 614 is fixedly installed on the rear side of the movable frame 613, and the transmission plate 614 is movably located inside the groove 607. A pull rod is movably installed through the rear end of the groove 607. A rod 615 is provided, and the rod body of the rod 615 is movably installed inside the transmission plate 614. A fixing block 618 is installed on the rear side of the output end of the hydraulic cylinder 5, and the fixing block 618 is connected to the upper end of the rod 615. A movable hole 616 is provided through the rear side of the lower inner surface of the groove 607. The rod body of the rod 615 is movably installed inside the movable hole 616. A pull plate 617 is installed at the lower end of the rod 615. The pull plate 617 is movably installed through the movable hole 616 and the groove 607, and the pull plate 617 is in contact with the lower surface of the transmission plate 614.

[0026] Hydraulic cylinder 5 pushes the upper mold 3 downward, allowing it to fit against the lower mold 2. Simultaneously, the upper mold 3 drives the guide frame 602 into the guide groove 604, assisting in precise fitting between the upper and lower molds. It also connects the first temporary storage tank 601 and the second temporary storage tank 603. The user can then inject liquid raw material into the molding cavity between the upper mold 3 and the lower mold 2 through the pouring pipe 7. The liquid raw material fills the molding cavity, allowing it to cool and solidify according to the shape of the cavity. A water pump then injects liquid into the first temporary storage tank 601 through the water injection pipe 605, allowing the liquid to flow within it. The liquid then flows through the guide frame 602 into the second temporary storage tank 603. Finally, the liquid in the second temporary storage tank 603 is drained into an external water tank for recycling through the drain pipe 606. This ensures that the liquid flows between the first temporary storage tank 601 and the second temporary storage tank 603, allowing the liquid to carry away the temperature inside the upper mold 3 and the lower mold 2, thereby cooling the liquid raw material, increasing the solidification speed of the liquid raw material, and lowering its temperature. After the raw material solidifies and forms, the water pump can stop working, and then the hydraulic cylinder 5 pulls the upper mold 3 upward, separating the upper mold 3 and the lower mold 2. At the same time, the output end of the hydraulic cylinder 5 will also drive the pull rod 615 to move through the fixed block 618. Then, when the pull rod 615 drives the pull plate 617 and the transmission plate 614 to fit together, as the pull rod 615 moves upward, the pull plate 617 pulls the transmission plate 614 and the movable frame 613 upward. Then, the movable frame 613 can drive the push rod 611 and the push plate 610 to move upward, allowing the push plate 610 to push the raw material out of the interior of the lower mold 2, realizing the material unloading work, which is simpler and faster.

[0027] Spring 612 is used to push push rod 611 and movable frame 613 to reset when upper mold 3 moves down, so that when upper mold 3 moves up again, it can push the raw material to perform the unloading operation.

[0028] The pull plate 617 and the movable hole 616 are used to assist the push rod 611 in moving. When the push rod 611 moves upward, the pull plate 617 and the transmission plate 614 are connected to the push rod 611 to control the opening distance between the upper mold 3 and the lower mold 2. This prevents the push rod 611 from pushing the raw material out at the same time as the upper mold 3 opens, which would cause the raw material and the upper mold 3 to get stuck together.

[0029] The working principle of this automotive water pump housing casting device:

[0030] In use, the hydraulic cylinder 5 first pushes the upper mold 3 downward, allowing it to fit against the lower mold 2. Simultaneously, the upper mold 3 drives the guide frame 602 into the guide groove 604, which assists in precise fitting between the upper mold 3 and the lower mold 2, and also connects the first temporary storage tank 601 and the second temporary storage tank 603. The user then injects liquid raw material into the forming cavity between the upper mold 3 and the lower mold 2 through the pouring pipe 7, filling the cavity. After cooling, the liquid raw material is shaped according to the form of the cavity. A water pump then injects liquid into the first temporary storage tank 601 through the water injection pipe 605, allowing the liquid to flow within it. The liquid then flows through the guide frame 602 into the second temporary storage tank 603. Finally, the liquid in the second temporary storage tank 603 is drained into an external water tank through the drain pipe 606. Internal recycling ensures the liquid flows between temporary storage tank 601 and temporary storage tank 603, allowing the liquid to carry away the heat from the upper mold 3 and lower mold 2, thus cooling the liquid raw material, increasing its solidification speed, and lowering its temperature. After the raw material solidifies, the water pump stops working, and the hydraulic cylinder 5 pulls the upper mold 3 upward, separating it from the lower mold 2. Simultaneously, the output end of the hydraulic cylinder 5 drives the pull rod 615 to move through the fixed block 618. When the pull rod 615 brings the pull plate 617 and the transmission plate 614 into contact, the pull plate 617 pulls the transmission plate 614 and the movable frame 613 upward as the pull rod 615 moves upward. The movable frame 613 then drives the push rod 611 and the push plate 610 upward, allowing the push plate 610 to push the raw material out of the lower mold 2, thus completing the material unloading process.

[0031] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
