Description
Technical Field
[0001] This invention relates to the field of casting technology, and more specifically, to a water pump housing casting equipment and its casting process. Background Technology
[0002] The water pump housing, made of high-strength, lightweight cast aluminum alloy, utilizes advanced casting technology to effectively solve problems such as air entrapment, shrinkage cavities, and cracks that are common in traditional casting. This process improves the internal density, achieves fine grain strengthening and plastic deformation strengthening, and gives the housing both high strength and excellent elongation.
[0003] In publicly available literature, patent publication number CN118808619A discloses a water pump housing casting equipment. This technology features a gear ring whose circumference is four times that of the gear. When the gear rotates half a turn, the gear ring rotates 22.5°, allowing the second through hole to completely pass over a first through hole. A computer program controls a second motor to ensure the angle at which the second motor drives the first gear to rotate, thus determining the communication area between the first and second through holes and achieving the function of regulating the flow speed of molten iron. However, this technology has the following problems.
[0004] Before casting a high-strength, tough, and lightweight aluminum alloy water pump housing, the mold must be preheated to the set temperature. If the mold is not heated to the set temperature and molten aluminum is injected by mistake, it will cause cold shuts and shrinkage defects inside the casting, which will seriously affect the product quality. More dangerously, the low temperature of the mold cavity will cause the molten aluminum to boil and splash instantly, resulting in a mold explosion and splashing accident, which seriously threatens operational safety and greatly reduces the quality and safety of casting.

The flow channel is located below the flow guide block.
[0007] In a preferred embodiment, a gap is provided between the lifting block and the guide block, and the lower surface of the lifting block is arranged parallel to the upper surface of the guide block.
[0008] In a preferred embodiment, the width of the sleeve is greater than the width of the groove, and the sleeve post is perpendicular to the guide block.
[0009] In a preferred embodiment, the pressure-blocking member includes: A linkage bar is installed at one end on one side of a flow guide block, and a slanted pressure plate is connected to the other end of the linkage bar. Both the slanted pressure plate and the flow guide block are fixedly connected to the linkage bar. An inclined groove is inclinedly opened on the inner wall of an inclined pressure plate. A linkage shaft is installed on the inner wall of the inclined groove. The linkage shaft is slidably connected to the inclined pressure plate to which the inclined groove belongs. One end of the linkage shaft is fixedly connected to a blocking block. A booster cylinder is slidably connected to the outer wall of the power plate. A first electric cylinder is installed at one end of the booster cylinder. The output end of the first electric cylinder is fixedly connected to the power plate. The first electric cylinder is used to push the power plate to move. An injection head is fixedly connected to the other end of the pressure cylinder, and the injection head is fixedly connected to the lower mold; A socket block is fixed to one side of the blocking groove block. A guide rod is installed on the inner wall of the socket block. The guide rod is used to guide the sliding of the socket block and is fixedly connected to the pressure cylinder.
[0010] In a preferred embodiment, the blocking block is inclined and is slidably connected to the booster cylinder.
[0011] In a preferred embodiment, a gap is provided between the blocking block and the guide rod, and both the guide rod and the sleeve block are inclined.
[0012] In a preferred embodiment, the preheating detection element includes; A temperature sensor is disposed on one side of the injection groove.

[0013] In a preferred embodiment, guide shafts are fixed on the upper surface of the lower mold and near its four corners, and the guide shafts are slidably connected to the upper mold.

A water pump housing casting process, the method comprising the following steps: Step 1: Mold preheating and temperature monitoring. The resistance heater is started to preheat the lower mold and upper mold after mold closing. The temperature of the upper mold is monitored in real time by the temperature sensor and the signal is transmitted to the wireless controller. Step 2: Safety self-check and status confirmation. When the wireless controller determines that the temperature is not up to standard, it automatically moves the sealing block up to block the injection tank, moves the guide block down to open the diversion tank, and inserts the blocking block into the blocking power plate. If the temperature is up to standard, the equipment remains in normal condition, and the sealing block moves down to open the injection tank. Step 3: Aluminum liquid injection and pressure holding molding. After preheating to the required standard, the aluminum liquid for casting the water pump housing is injected into the booster cylinder. The first electric cylinder is started to drive the power plate and press the aluminum liquid for casting the water pump housing into the space between the upper and lower molds through the injection head. Step 4: Cooling operation. Open the valve to introduce cooling water for cooling. After cooling is completed, the water pump housing is obtained.
[0014] The technical effects and advantages of the present invention.
[0015] This invention employs interlocking components, pressure-blocking components, and preheating detection components. When the preheating detection component detects that the mold preheating temperature is below standard, the wireless controller activates a linear servo motor, causing the sealing block to move upward and block the injection groove. Simultaneously, the guiding block moves downward, opening the bottom of the injection groove and allowing the flow channel to safely guide the molten aluminum. The guiding block synchronously drives the pressure-blocking component to move the blocking block downward and block the movement of the power plate. Thus, when preheating is insufficient, it achieves both aluminum liquid blocking and automatic diversion, as well as mechanical locking of the pressurization system, preventing molten aluminum from accidentally entering the mold cavity or being forcibly injected. This effectively prevents cold shuts, shrinkage, and mold bursting accidents, significantly improving the quality and safety of casting.
[0016] When the temperature is not up to standard, the linear servo motor pushes the lifting block to move upward, so that the sealing block can reliably seal the injection tank; at the same time, the alumina fiber rope pulls the moving block and the guide block downward to open the flow channel. The spring provides continuous rebound force to the moving block to ensure transmission tension and stable operation, so that the aluminum liquid can automatically flow back to the crucible when the preheating is insufficient, avoiding manual intervention and improving the automation of operation and process controllability.
[0017] 3. When the guide block moves downward, the inclined pressure plate is driven to press down through the linkage bar. The inclined groove pushes the linkage shaft to move laterally, so that the blocking block is inserted along the guide rod and jams the power plate. When the preheating is insufficient, the action of the first electric cylinder is physically restricted. Even if there is a misoperation, the power plate cannot be driven to inject aluminum liquid. This systematically eliminates the risk of forced die casting and further enhances the safety protection level of the equipment. Attached Figure Description

Detailed Implementation
[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1:
[0029] like Figure 1 - Figure 2 The water pump housing casting equipment shown includes a lower mold 1, an upper mold 2 above the lower mold 1; an injection groove 3, formed on the inner wall of the lower mold 1; an interlocking linkage, installed on the inner wall of the injection groove 3, with a sealing block 4 and a flow guide block 5 installed on the interlocking linkage; a pressure baffle, installed on one side of the flow guide block 5, with a channel blocking block 6 on the pressure baffle, and a power plate 7 below the channel blocking block 6; and a preheating detection component, located on one side of the injection groove 3.
[0030] In this embodiment, after the lower mold 1 and the upper mold 2 are closed, when the preheating detection component detects that the preheating temperature has not reached the set threshold, the interlocking component drives the sealing block 4 to block the injection groove 3, and at the same time drives the flow guide block 5 to open the bottom of the injection groove 3 to divert the aluminum liquid for pump housing casting; simultaneously, the flow guide block 5 drives the pressure blocking component, so that the pressure blocking component drives the blocking groove block 6 to block the power plate 7, ensuring that when the preheating temperature is not up to standard, the aluminum liquid for pump housing casting can be prevented from entering between the lower mold 1 and the upper mold 2, and the aluminum liquid for pump housing casting can be safely diverted simultaneously, and the workers are prevented from forcibly pressurizing and transporting the aluminum liquid for pump housing casting. Safe quality improvement treatment is carried out from multiple positions, which greatly improves the casting quality and casting safety of the pump housing. Example 2:
[0031] In this embodiment, as Figure 2 - Figure 5 As shown, the interlocking linkage includes: a lifting block 8, slidably connected to the inner wall of the injection groove 3, the lifting block 8 being fixedly connected to the sealing block 4, a linear servo motor 9 mounted on the lower surface of the lifting block 8, the linear servo motor 9 being used to push the lifting block 8 to move, and the output end of the linear servo motor 9 being fixedly connected to the lifting block 8; an alumina fiber rope 10, installed on one side of the linear servo motor 9, one end of the alumina fiber rope 10 being fixedly connected to a moving block 11, and the other end of the alumina fiber rope 10 being fixedly connected to the lifting block 8; and a sleeve post 12, fixedly installed on the top of the moving block 11, with a guide rod 13 penetrating through the inner wall of the sleeve post 12, the guide rod 13 being fixedly connected to the lower mold 1, and the guide rod 13 being used to guide the sliding of the sleeve post 12. One end of the sleeve post 12 is fixedly connected to the guide block 5; the sleeve strip 14 is fixedly connected to the outer wall of the sleeve post 12 and located on one side of the guide rod 13, and the sleeve strip 14 is slidably connected to the lower mold 1. A groove 15 is provided on one side of the sleeve strip 14, and the groove 15 is used to guide the sleeve post 12 to slide; the groove guide block 16 is installed on the outer wall of the alumina fiber rope 10, and the groove guide block 16 is fixedly connected to the lower mold 1. The groove guide block 16 is used to guide the alumina fiber rope 10 to slide; the spring piece 34 is located on one side of the groove guide block 16, and both the moving block 11 and the groove guide block 16 are fixedly connected to the spring piece 34. The spring piece 34 is used to provide elastic force to the moving block 11; the flow channel 33 is opened below the guide block 5. There is a gap between the lifting block 8 and the guide block 5, and the lower surface of the lifting block 8 is parallel to the upper surface of the groove guide block 16. The width of the connecting strip 14 is greater than the width of the groove 15, and the sleeve 12 and the guide block 5 are set vertically.
[0032] In this embodiment, when the preheating temperature is detected to be below the set threshold, the linear servo motor 9 is activated by the wireless controller 28. The output end of the linear servo motor 9 pushes the lifting block 8 to move upward, and the lifting block 8 drives the sealing block 4 to move upward. The sealing block 4 moves upward from inside the injection groove 3, thereby pressing the sealing block 4 against the top of the inner wall of the upper mold 2, and the sealing block 4 begins to block the injection groove 3.
[0033] Simultaneously, lifting block 8 drives alumina fiber rope 10 to pull moving block 11 downward. At the same time, alumina fiber rope 10 slides along the inner wall of guide block 16. Moving block 11 drives sleeve 12 downward, and sleeve 12 slides down along the outer wall of guide rod 13. Simultaneously, lower mold 1 supports guide rod 13, ensuring sleeve 12 slides downward along the inside of slide groove 15. Simultaneously, sleeve 12 drives connecting strip 14 downward, continuously moving downward to block slide groove 15. At the same time, moving block 11 pushes the top of spring piece 34 downward, while guide block 16 supports the bottom of spring piece 34. Thus, spring piece 34 provides a rebound force to moving block 11, ensuring that moving block 11 provides taut tension to alumina fiber rope 10, ensuring the alumina fiber rope... 10. The moving block 11 is pulled stably, and the sleeve 12 will drive the guide block 5 to move down. The guide block 5 moves down from the inside of the injection tank 3, opening the bottom of the injection tank 3, so that the bottom of the injection tank 3 begins to connect with the guide tank 33. In this way, when the aluminum molten aluminum for the pump housing enters the injection tank 3, it is firmly blocked by the sealing block 4. At the same time, the aluminum molten aluminum for the pump housing can enter the guide tank 33 along the injection tank 3, and flow back to the crucible support position from the guide tank 33. This ensures that the aluminum molten aluminum for the pump housing will not enter the gap between the lower mold 1 and the upper mold 2, which has not been preheated sufficiently. At the same time, the wireless controller 28 remotely connects to the computer of the back-end management personnel, so that the back-end management personnel can perform management operations and prevent on-site manual violations. Example 3:
[0034] In this embodiment, as Figure 6 - Figure 9 As shown, the pressure-blocking component includes: a linkage bar 17, one end of which is installed on one side of the guide block 5, and the other end of the linkage bar 17 is connected to an inclined pressure plate 18, both the inclined pressure plate 18 and the guide block 5 being fixedly connected to the linkage bar 17; an inclined groove 19, which is inclinedly opened on the inner wall of the inclined pressure plate 18, and a linkage shaft 20 is installed on the inner wall of the inclined groove 19, the linkage shaft 20 being slidably connected to the inclined pressure plate 18 to which the inclined groove 19 belongs, and one end of the linkage shaft 20 being fixedly connected to the blocking block 6; and a booster cylinder 21, which is slidably connected to the outside of the power plate 7. The pressure cylinder 21 has a first electric cylinder 22 installed at one end, with its output end fixedly connected to the power plate 7. The first electric cylinder 22 is used to move the power plate 7. An injection head 23 is fixedly connected to the other end of the pressure cylinder 21 and is fixedly connected to the lower mold 1. A sleeve block 24 is fixed to one side of the blocking block 6, and a guide rod 25 is installed on the inner wall of the sleeve block 24. The guide rod 25 is used to guide the sliding of the sleeve block 24 and is fixedly connected to the pressure cylinder 21. The blocking block 6 is inclined and is slidably connected to the pressure cylinder 21. There is a gap between the blocking block 6 and the guide rod 25, and both the guide rod 25 and the sleeve block 24 are inclined.
[0035] In this embodiment, when the guide block 5 moves down, it will drive the linkage bar 17 to move down synchronously. The linkage bar 17 will cause the inclined pressure plate 18 to move down. The inclined groove 19 on the inner wall of the inclined pressure plate 18 will tilt and squeeze the linkage shaft 20. After the linkage shaft 20 is squeezed, it will drive the blocking block 6 to move downward. The blocking block 6 will drive the sleeve block 24 to move downward. The sleeve block 24 will start to move downward along the outer wall of the guide rod 25, ensuring that the blocking block 6 moves downward along the inner wall of the booster cylinder 21. In this way, the right side of the blocking block 6 will block the left side of the power plate 7. The operator will forcibly start the first electric cylinder 22. The pushing end of the first electric cylinder 22 will drive the power plate 7 to move to the left. The power plate 7 will also be limited and blocked by the blocking block 6, preventing the power plate 7 from squeezing the aluminum casting liquid of the water pump housing, thereby preventing high-pressure injection of the aluminum casting liquid of the water pump housing. Example 4:
[0036] In this embodiment, as Figure 1 As shown, the preheating detection component includes: a temperature sensor 26, which is disposed on one side of the injection groove 3 and is fixedly connected to the lower mold 1; a resistance heater 27 is installed on the upper surface of the lower mold 1 and located outside the temperature sensor 26, and the resistance heater 27 is used to heat the lower mold 1; and a wireless controller 28, which is disposed on the output end of the temperature sensor 26. Both the resistance heater 27 and the temperature sensor 26 are electrically connected to the wireless controller 28.
[0037] In this embodiment, the upper mold 2 and the lower mold 1 are first joined together. The resistance heater 27 is started by the wireless controller 28. The resistance heater 27 heats the upper mold 2. After heating, the temperature is sensed by the temperature sensor 26 inside the lower mold 1. When the temperature value sensed by the temperature sensor 26 does not reach the set threshold, the linear servo 9 is immediately started by the wireless controller 28. The output of the linear servo 9 starts to push the lifting block 8 upward, thus realizing intelligent control.
[0038] When the temperature value sensed by the temperature sensor 26 reaches the set threshold, the linear servo 9 is immediately activated by the wireless controller 28, and the output of the linear servo 9 begins to move down to reset. Example 5:
[0039] In this embodiment, as Figure 1 As shown, guide shafts 29 are fixed on the upper surface of the lower mold 1 and near its four corners. The guide shafts 29 are slidably connected to the upper mold 2. A sleeve plate 30 is fixed at the top of the guide shaft 29, and a second electric cylinder 31 is installed inside the sleeve plate 30. The output end of the second electric cylinder 31 is fixedly connected to the upper mold 2. A valve 32 is installed on both sides of the lower mold 1.
[0040] In this embodiment, during mold closing, the upper mold 2 is driven to move downward by the second electric cylinder 31. At the same time, the guide shaft 29 supports the sleeve plate 30, and the sleeve plate 30 supports the second electric cylinder 31. Thus, the upper mold 2 moves downward steadily along the outer wall of the multiple guide shafts 29. Simultaneously, the upper mold 2 presses against the upper surface of the lower mold 1, realizing the mold closing operation between the lower mold 1 and the upper mold 2. At the same time, one valve 32 is threadedly connected to the cooling water inlet pipe, and another valve 32 is connected to the water outlet pipe. When the preheating temperature is at the set threshold, the output end of the linear servo motor 9 moves downward and resets, which drives the lifting block 8 to move downward. The lifting block 8 drives the sealing block 4 to move downward, and the sealing block 4 opens the injection groove 3. At the same time, the alumina fiber rope 10 no longer pulls the moving block 11. Under the action of the spring plate 34, the moving block 11 moves upward. The moving block 11 drives the sleeve column 12 to move upward, and the sleeve column 12 drives the guide block 5 to move upward and be located inside the injection groove 3, thereby separating the injection groove 3 from the diversion groove 33.
[0041] The molten aluminum for the water pump housing is injected into the booster cylinder 21, while the injection head 23 is aligned with the injection groove 3. By activating the first electric cylinder 22, the first electric cylinder 22 drives the power plate 7 to move to the left. The power plate 7 squeezes the molten aluminum for the water pump housing from the booster cylinder 21 into the injection head 23, and then into the injection groove 3. From the injection head 23, it is injected into the gap between the lower mold 1 and the upper mold 2. When cooling is required, a valve 32 is opened to introduce cooling water into the cooling space inside the lower mold 1 to cool the water pump housing. The cooled water is then discharged through another valve 32.
[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
