Description

Technical Field

[0001] This utility model belongs to the field of precision stamping technology, specifically relating to a precision stamping mold for water pump bodies. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process metal or non-metal into parts. Types of stamping dies include blanking dies, drawing dies, bending dies, flanging dies, and hemming dies, and they are widely used in various fields, including automobiles, electronics, and daily hardware. Materials used to manufacture stamping dies include steel, cemented carbide, steel-bonded cemented carbide, zinc-based alloys, low-melting-point alloys, aluminum bronze, and polymer materials, among others. Steel is the most common material used in stamping die manufacturing. When making stamping dies, process analysis should be conducted based on the shape characteristics, dimensional accuracy, and surface quality requirements of the workpiece to determine the basic operating procedures.

[0003] High-precision stamping dies consist of fixed and moving parts. During the stamping process, the stamping die generates a lot of heat. Existing stamping dies do not have a structure to dissipate and cool the heat, which causes the stamping process to be out of sync with the heat dissipation process, resulting in a significant loss of energy and affecting the stamping effect of the pump body. Utility Model Content

[0004] The purpose of this invention is to provide a precision stamping mold for water pump bodies, in order to solve the problem mentioned in the background art that the high-precision stamping mold consists of a fixed part and a moving part. During the stamping process, the stamping mold generates a lot of heat. The existing stamping mold does not have a structure to dissipate and cool the heat, which causes the stamping process to be out of sync with the heat dissipation process, resulting in a lot of extra energy loss and affecting the stamping effect of the pump body.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a base frame and a top plate mounted on the upper surface of the base frame. An electric push rod is mounted on the lower surface of the top plate, and a stamping template is mounted on the output shaft end of the electric push rod. A forming mold base is mounted on the upper surface of the base frame, and a mold groove is formed on the upper surface of the forming mold base. Water storage cylinders with openings on their upper surfaces are mounted on both the left and right sides of the upper surface of the base frame. Two water storage chambers are formed inside the forming mold base, located on the left and right sides of the mold groove, respectively. Two U-shaped water guide pipes are connected and mounted on the base frame. One end of each water guide pipe is connected to a water storage cylinder, and the other end extends into the forming mold base and is connected to a water storage chamber. Mounting plates are mounted on both the left and right sides of the stamping template, and a movable rod is mounted on the lower surface of the mounting plate. A piston is installed inside the water storage cylinder, and the bottom end of the movable rod is fixedly connected to the piston.

[0006] By adopting the above scheme, a movable rod, piston, water tank, and water storage chamber are set up. The electric push rod drives the stamping template to move downward, which stamps the pump body. Combined with the moving of the mounting plate along with the stamping template, the movable rod moves. Combined with the movement of the piston in the water tank, the atmospheric pressure inside the water tank is increased. Combined with the function of the water guide pipe, water is forced into the water storage chamber. This allows the pump body to be stamped while the forming mold base is cooled. The stamping process and the heat dissipation process can be synchronized, thus improving the stamping effect of the pump body.

[0007] In the above scheme, it should be noted that the electric push rod is electrically connected to an external power source.

[0008] In a preferred embodiment, the lower surface of the base frame is provided with a channel, and the lower surface of the molding base is provided with two outlet holes communicating with the mold groove. Two support plates are installed on the lower surface of the molding base opposite to the two outlet holes. Outlet rods are slidably installed on the support plates. The top end of the outlet rod extends through the outlet hole and is equipped with a push plate. The bottom ends of the two outlet rods are equipped with the same base plate. A spring is sleeved on the outlet rod and its two ends are fixedly connected to the base plate and the support plate respectively.

[0009] By adopting the above scheme, by setting an export rod, a support plate, a spring, and a base plate, the support plate provides sliding support for the export rod, the export rod provides fixed support for the push plate, and the spring provides elastic support for the export rod. This allows the export rod to be moved by the reaction force of the spring and the push plate to push the stamped pump body out of the mold groove, thus facilitating the removal of the pump body from the mold groove.

[0010] In a preferred embodiment, an annular fixing plate is installed inside the outlet hole, the outlet rod passes through the fixing plate, and four limiting rods are installed on the lower surface of the push plate, the four limiting rods being arranged in coordination with the fixing plate.

[0011] By adopting the above scheme, by setting a fixed plate and a limiting rod, the limiting rod and the fixed plate cooperate to make the push plate drive the limiting rod to move downward into the outlet hole. The limiting rod and the fixed plate abut against each other to ensure that the upper surface of the push plate and the inner bottom surface of the mold groove are on the same horizontal plane.

[0012] In a preferred embodiment, a heat dissipation cylinder is installed on the outer surface of the water storage cylinder, and a plurality of heat dissipation fins are installed on the outer surface of the heat dissipation cylinder.

[0013] By adopting the above scheme, a heat dissipation cylinder is set up. The heat dissipation cylinder is connected to the outside of the water storage cylinder to quickly dissipate the heat of the water inside the water storage cylinder after it has been heated. This keeps the water inside the water storage cylinder at a low temperature. Combined with the function of the heat dissipation fins, the heat dissipation of the water inside the water storage cylinder is accelerated.

[0014] In a preferred embodiment, an external pipe is connected to the water pipe, and a threaded cap is threaded onto the bottom end of the external pipe. A rubber plug is installed inside the threaded cap, and one end of the rubber plug extends into the external pipe.

[0015] By adopting the above scheme, by setting an external pipe, a threaded cap, and a rubber stopper, the external pipe facilitates the drainage and replacement of liquid that has been stored in the water tank for a long period of time. The threaded cap seals the opening of the external pipe, thus preventing air leakage. The rubber stopper further enhances the sealing of the opening of the external pipe, thereby improving the sealing performance of the water pipe.

[0016] In a preferred embodiment, two guide rods are slidably installed through both ends of the stamping template, and the bottom ends of the two guide rods on the same side are equipped with the same guide plate. Guide grooves that cooperate with the guide plates are opened on both the left and right sides of the upper surface of the forming mold base.

[0017] By adopting the above scheme, guide rods and guide plates are set up. The guide rods provide sliding support for the guide plates through their sliding installation. Combined with the cooperation between the guide plates and the guide grooves, the stamping template is guided, thereby enabling the stamping template to perform stamping work stably.

[0018] In a preferred embodiment, a second spring is sleeved on the guide rod, with its two ends fixedly connected to the stamping template and the guide plate respectively, and the top ends of the two guide rods on the same side are equipped with the same connecting plate.

[0019] By adopting the above scheme, by setting up spring 2 and connecting plate, the elasticity of spring 2 is used to provide elastic support for the guide rod, and the impact force of the stamping template pressing downward is buffered, so that the stamping template can perform stamping work stably. Combined with the function of connecting plate, the top of the guide rod is fixed together, thus simplifying the structure.

[0020] In a preferred embodiment, an annular cover plate is installed on the upper surface of the water storage tank. The inner diameter of the cover plate is smaller than the outer diameter of the piston, and the bottom end of the movable rod extends through the cover plate.

[0021] By adopting the above solution, a cover plate is installed. The cover plate is ring-shaped, which can cover the top of the water storage tank without affecting the movement of the movable rod, thereby preventing dust from entering the water storage tank and maintaining the cleanliness of the inside of the water storage tank.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The pump body is precision stamped into a mold by setting up a movable rod, piston, water storage cylinder, and water storage chamber. The electric push rod drives the stamping template to move downward, which stamps the pump body. Combined with the movement of the mounting plate along with the stamping template, the movable rod moves. Combined with the movement of the piston in the water storage cylinder, the atmospheric pressure inside the water storage cylinder is increased. Combined with the water guide pipe, water is forced into the water storage chamber. This allows the stamping of the pump body to be carried out simultaneously with the cooling of the forming mold base. The stamping process and the heat dissipation process can be synchronized, thus improving the stamping effect of the pump body.

[0024] The pump body is precision stamped into a mold by setting an outlet rod, a support plate, a spring, and a base plate. The support plate provides sliding support for the outlet rod, and the outlet rod provides fixed support for the push plate. The spring provides elastic support for the outlet rod, which is then driven by the reaction force of the spring to move the outlet rod. The push plate then pushes the stamped pump body out of the mold groove, making it easy to remove the pump body from the mold groove. Attached Figure Description

[0030] Please see Figure 1-4 This utility model provides a precision stamping mold for a water pump body, including a base frame 1 and a top plate 2 mounted on the upper surface of the base frame 1. The top plate 2 provides fixed support for an electric push rod 3. The electric push rod 3 is mounted on the lower surface of the top plate 2, and drives a stamping template 4 to move using the electric push rod 3.

A forming mold base 5 is mounted on the upper surface of the base frame 1, and the stamped part is placed on the forming mold base 5 to form the pump body. The upper surface of the molding die 5 is provided with a mold groove. Water storage cylinders 7 with openings on the upper surface are installed on both the left and right sides of the upper surface of the base frame 1. The water storage cylinders 7 store water. Two water storage chambers are provided inside the molding die 5 to cool it. The two water storage chambers are located on the left and right sides of the mold groove, respectively. Two U-shaped water guide pipes 11 are connected to the base frame 1, connecting the water storage cylinders 7 to the water storage chambers. One end of the water guide pipe 11 is connected to the water storage cylinder 7. The other end of the water guide pipe 11 is connected to the molding die 5 and connected to the water storage chamber. The left and right sides of the stamping template 4 are equipped with mounting plates 6, which are used to fix and support the movable rod 10. The movable rod 10 is installed on the lower surface of the mounting plate 6, which is used to fix and support the piston 8. The piston 8 is installed in the water storage cylinder 7, and the bottom end of the movable rod 10 is fixedly connected to the piston 8. By setting up the movable rod 10, piston 8, water storage cylinder 7 and water storage chamber, the electric push rod 3 drives the stamping template 4 to move downward to perform stamping work on the pump body. Combined with the movement of the mounting plate 6 with the stamping template 4, the movable rod 10 is driven to move. Combined with the movement of the piston 8 in the water storage cylinder 7, the atmospheric pressure in the water storage cylinder 7 is increased. Combined with the function of the water guide pipe 11, water is forced into the water storage chamber, so that the pump body can be stamped at the same time and the molding die 5 can be cooled at the same time. The stamping process can be synchronized with the heat dissipation process, thus improving the stamping effect of the pump body.

[0031] The lower surface of the base frame 1 has a channel. The lower surface of the molding die 5 has two outlet holes that communicate with the mold groove. The outlet holes are used to accommodate the outlet rods 13. Two support plates 15 are installed on the lower surface of the molding die 5, directly opposite the two outlet holes. The support plates 15 provide sliding support for the outlet rods 13. The outlet rods 13 are slidably installed through the support plates 15. The outlet rods 13 provide fixed support for the push plate 17. The top of the outlet rods 13 extends through the outlet hole and is fitted with the push plate 17. The push plate 17 is used to push the stamped pump body out of the mold groove. The bottom ends of the two outlet rods 13 The same base plate 16 is installed, and springs 14 are sleeved on the guide rod 13, with their two ends fixedly connected to the base plate 16 and the support plate 15 respectively. By setting up the guide rod 13, the support plate 15, the springs 14 and the base plate 16, the guide rod 13 is slidably supported by the support plate 15, and the push plate 17 is fixedly supported by the guide rod 13. The guide rod 13 is elastically supported by the springs 14, so that the guide rod 13 can be moved by the reaction force of the springs 14 and the push plate 17 can be used to push the stamped pump body out of the mold groove, so that the pump body can be easily removed from the mold groove.

[0032] An annular fixing plate 12 is installed inside the outlet hole. The outlet rod 13 passes through the fixing plate 12. Four limiting rods 18 are installed on the lower surface of the push plate 17. The four limiting rods 18 are arranged in cooperation with the fixing plate 12. By setting the fixing plate 12 and the limiting rods 18, the limiting rods 18 cooperate with the fixing plate 12 to make the push plate 17 drive the limiting rods 18 to move downward into the outlet hole. The limiting rods 18 and the fixing plate 12 abut against each other to ensure that the upper surface of the push plate 17 and the inner bottom surface of the mold groove are on the same horizontal plane.

[0033] A heat dissipation cylinder 26 is installed on the outer surface of the water storage cylinder 7. The heat dissipation cylinder 26 dissipates the heat inside the water storage cylinder 7. Several heat dissipation fins are installed on the outer surface of the heat dissipation cylinder 26. By setting up the heat dissipation cylinder 26 and using the effect of the heat dissipation cylinder 26 being sleeved on the outside of the water storage cylinder 7, the water inside the water storage cylinder 7 after it has been heated can be quickly cooled down, so that the water inside the water storage cylinder 7 can always be kept at a low temperature. Combined with the effect of the heat dissipation fins, the heat dissipation of the water inside the water storage cylinder 7 is accelerated.

[0034] An external connector 19 is connected to the water pipe 11. A threaded cap 20 is threaded onto the bottom end of the external connector 19, and a rubber plug 21 is installed inside the threaded cap 20. One end of the rubber plug 21 extends into the external connector 19. By setting up the external connector 19, the threaded cap 20, and the rubber plug 21, the external connector 19 facilitates the drainage and replacement of liquids that have been stored in the water tank 7 for a long period of time. The threaded cap 20 seals the opening of the external connector 19, thus preventing air leakage. The rubber plug 21 further enhances the sealing of the opening of the external connector 19, thereby improving the sealing performance of the water pipe 11.

[0035] Two guide rods 22 are slidably installed through both ends of the stamping template 4. The bottom ends of the two guide rods 22 on the same side are equipped with the same guide plate 23. Guide grooves are provided on both the left and right sides of the upper surface of the forming mold base 5 to cooperate with the guide plate 23. By setting the guide rods 22 and the guide plate 23, the guide rods 22 provide sliding support for the guide plate 23 through their sliding installation. Combined with the cooperation of the guide plate 23 and the guide groove, the stamping template 4 is guided, so that the stamping template 4 can stably carry out the stamping work.

[0036] A second spring 24 is sleeved on the guide rod 22, with its two ends fixedly connected to the stamping template 4 and the guide plate 23 respectively. The top ends of the two guide rods 22 on the same side are equipped with the same connecting plate 25. By setting the second spring 24 and the connecting plate 25, the elasticity of the second spring 24 provides elastic support for the guide rod 22, buffering the impact force of the stamping template 4 pressing downward, so that the stamping template 4 can perform stamping work stably. Combined with the function of the connecting plate 25, the top ends of the guide rods 22 are fixed together, thus simplifying the structure.

[0037] An annular cover plate 9 is installed on the upper surface of the water storage tank 7. The inner diameter of the cover plate 9 is smaller than the outer diameter of the piston 8. The bottom end of the movable rod 10 extends through the cover plate 9. By setting the cover plate 9, the cover plate 9 can cover the top of the water storage tank 7 without affecting the movement of the movable rod 10, thereby preventing dust from entering the water storage tank 7 and maintaining the cleanliness of the inside of the water storage tank 7.

[0038] In use, the stamping assembly is placed in the mold cavity, and then the electric push rod 3 is activated. The electric push rod 3 drives the stamping template 4 to move downward. The downward movement of the stamping template 4 causes the mounting plate 6 to move, which in turn causes the movable rod 10 to move downward. The bottom end of the movable rod 10 drives the piston 8 to move downward. The piston 8 moves downward inside the water storage tank 7. At this time, the water in the water storage tank 7 enters the water storage chamber through the water guide pipe 11. When the stamping template 4 moves downward, it drives the guide rod 22 to move. The movement of the guide rod 22 drives the guide plate 23 to move downward. The guide plate 23 moves downward and gradually enters the guide groove. As the stamping template 4 moves downward, it squeezes the spring 14 and the push plate 17. At this time, the push plate 17 is squeezed and enters the outlet hole, becoming flush with the inner wall of the mold cavity. The downward movement of the push plate 17 drives the outlet rod 13. The guide rod 13 slides on the fixed plate 12 to squeeze the spring 24. The push plate 17 drives the limiting rod 18 into the guide hole. When the bottom end of the limiting rod 18 abuts against the fixed plate 12, the push plate 17 is flush with the inner wall of the mold groove. When the stamping plate 4 moves upward to reset after stamping, the water in the water storage chamber returns to the water storage cylinder 7 with the upward movement of the piston 8. The push plate 17 moves upward under the reaction force of the spring 24. The outer pipe 19 facilitates the discharge and replacement of liquid that has been used for a long time in the water storage cylinder 7. Combined with the function of the threaded cap 20, the pipe opening of the outer pipe 19 is sealed to prevent air leakage. Combined with the function of the rubber plug 21, the sealing of the pipe opening of the outer pipe 19 is strengthened, thereby improving the sealing performance of the water guide pipe 11.
