Description

Technical Field

[0001] This application relates to the field of injection molding equipment technology, and in particular to a high-quality injection molding equipment for electronic water pump housings. Background Technology

[0002] Electronic water pumps are widely used in the water circulation, cooling, or water supply systems of special vehicles such as new energy vehicles and RVs. In the traditional injection molding production of electronic water pump housings, injection molding, demolding, and quality inspection are usually carried out in separate steps. This process is not only inefficient but also prone to product deformation or damage during demolding, increasing production losses.

[0003] Currently, Chinese utility model patent application CN 212343159U, published on January 12, 2021, discloses an injection molding machine, including a base. An electric linear module is fixedly installed on the upper surface of the base near the right side. A first housing is fixedly installed on the upper surface of the electric linear module, and an injection assembly is installed inside the first housing. A heating and conveying assembly is located on the left side of the injection assembly. A feeding box is fixedly installed on the upper surface of the heating and conveying assembly through a feeding pipe. A feeding mechanism is provided on the feeding pipe, and a crushing mechanism is provided inside the feeding box. This utility model adds a crushing function for the raw materials, effectively avoiding blockage of the feeding pipe. It also adds a feeding speed adjustment function, ensuring that the raw materials enter the heating and conveying assembly evenly. The heating and conveying assembly provides stable material transport, improving production quality. Furthermore, it adds a function to collect heat and unpleasant odors from the heating and conveying assembly, and purifies the odors. It also preheats the raw materials in the feeding box with hot air, making it more environmentally friendly and energy-efficient.

[0004] In injection molding machines in related technologies, after the injection mold is formed, it is necessary to wait for a period of time for the mold to cool down before demolding. If it is not possible to determine whether the mold is fully formed, demolding the mold can easily cause deformation or damage, affecting the mold's precision, increasing production losses, and reducing work efficiency.

[0005] Therefore, it is necessary to provide a high-quality injection molding equipment for electronic water pump housings to solve the above problems. Utility Model Content

[0006] This application provides a high-quality electronic water pump housing injection molding equipment to improve the technical problems in related technologies, such as the inability of the mold to cool and form quickly, the inability to control the mold cooling and forming process, and the resulting impact on mold precision.

[0007] This application provides a high-quality electronic water pump housing injection molding equipment, including a base plate, an upper mold, a lower mold, an injection pipe, and a cooling assembly. The cooling assembly includes a cooling tank, a water tank, a water pump, a water delivery pipe, and a cooling tube. The cooling tank is mounted on the base plate, the water tank is mounted on the cooling tank, the water pump is mounted on the cooling tank, one end of the water delivery pipe is mounted on the cooling tank, and the other end of the water delivery pipe is mounted on the water pump. The cooling tube is located inside the cooling tank, and its output and input ends are mounted on the water pump. The lower mold is mounted on the cooling tank and has a lower mold cavity. The upper mold is mounted on the lower mold and has an upper mold cavity. The injection pipe is mounted on the upper mold, and one end of the injection pipe communicates with the upper mold cavity through the upper mold.

[0008] The technical solutions described above in this application embodiment have at least the following technical effects: After injection molding of the upper mold cavity and the lower mold cavity in the upper mold and the lower mold through the injection pipe, the water in the water tank is transmitted to the water pump through the water supply pipe, and the water pump transmits the water to the cooling pipe in the cooling tank. During the continuous circulation of the liquid in the cooling pipe by the water pump, the injection molded part is cooled down, thereby accelerating the cooling and molding speed of the injection molded part, increasing work efficiency, and reducing production losses.

[0009] The high-quality electronic water pump housing injection molding equipment provided in this application embodiment can quickly reduce the temperature of the injection molded parts by circulating coolant to the cooling pipes through a cooling component and a water pump, so that the parts can reach the demolding conditions more quickly. Compared with natural cooling or air cooling, the water cooling system has a faster cooling speed, which greatly shortens the injection molding cycle and improves production efficiency. The cooling system can work continuously to ensure that it can cool down quickly after each injection molding, so that the equipment can run continuously and reduce downtime caused by excessive cooling time.

[0010] In some embodiments, a heating block is provided inside the injection tube.

[0011] In some embodiments, a temperature sensor is provided on the lower mold.

[0012] In some embodiments, a locking assembly is provided on the lower mold. The locking assembly includes a baffle, a rotating handle, a spring, a push rod, and a lock cylinder. A limiting groove is formed on the lower mold. The baffle is disposed on the lower mold through the limiting groove. The push rod is movably disposed on the baffle. One end of the spring abuts against the baffle, and the other end of the spring abuts against the push rod. The lock cylinder is disposed on the end of the push rod near the upper mold. The upper mold is provided with a lock cylinder.

[0013] In some embodiments, the lower mold is provided with a positioning post, the upper mold is provided with a positioning groove, and the upper mold is provided with a through hole.

[0014] In some embodiments, the upper mold has vent holes.

[0015] In some embodiments, the water tank has a connection hole, through which a connection cover is provided. Attached Figure Description

[0023] Based on this, in order to improve the technical problems existing in related technologies, such as the inability of molds to cool and form quickly and the inability to control the cooling and forming of molds, which affects the accuracy of molds, the embodiments of this application provide the following solutions.

[0024] Please refer to the following: Figures 1 to 5This application provides a high-quality electronic water pump housing injection molding equipment. The high-quality electronic water pump housing injection molding equipment includes a base plate 1, an upper mold 11, a lower mold 13, an injection tube 2, and a cooling assembly 3. The lower mold 13 is disposed on the cooling assembly 3 and has a lower mold cavity 14. The upper mold 11 is disposed on the lower mold 13 and has an upper mold cavity 12. The injection tube 2 is disposed on the upper mold 11, and one end of the injection tube 2 is connected to the upper mold cavity 12 through the upper mold 11.

[0025] In some embodiments, please refer to the following: Figures 1 to 3 The cooling assembly 3 includes a cooling box 31, a water tank 32, a water pump 33, a water supply pipe 34, and a cooling pipe 35. The cooling box 31 is mounted on the base plate 1, the water tank 32 is mounted on the cooling box 31, the water pump 33 is mounted on the cooling box 31, one end of the water supply pipe 34 is mounted on the cooling box 31, and the other end of the water supply pipe 34 is mounted on the water pump 33. The cooling pipe 35 is mounted inside the cooling box 31, and the output end and input end of the cooling pipe 35 are mounted on the water pump 33. A temperature sensor 37 is mounted on the lower mold 13, a heating block 21 is mounted inside the injection tube 2, and a connection hole is provided on the water tank 32, through which a connection cover 36 is mounted.

[0026] With this setup, before using the injection molding equipment, coolant is added to the connection hole by opening the connection cover 36. After injection molding is completed through the injection tube 2 into the upper mold 11 and the upper mold cavity 12 and the lower mold cavity 14 of the lower mold 13, the heating block 21 on the injection tube 2 starts working simultaneously, reducing the problem of solidification of the injection liquid in the injection tube 2, which could cause damage to the injection molded parts. The coolant in the water tank 32 is transferred to the water pump 33 through the water pipe 34, and then the water pump 33 transfers the coolant to the cooling pipe 35 in the cooling box 31. As the water pump 33 continuously circulates the liquid in the cooling pipe 35, it cools and lowers the temperature of the injection molded parts, thereby accelerating the cooling and molding speed of the injection molded parts. When the temperature reaches a certain level, the injection molded parts are formed, the temperature sensor 37 works, and the injection molded parts are demolded, thus increasing work efficiency and reducing production losses. Thus, through the coolant circulation system, the injection molded parts can be quickly cooled to the demolding temperature after molding, greatly shortening the cooling time and accelerating the production cycle. Compared with traditional cooling methods, this method can significantly improve the production efficiency of the equipment. The heating block 21 inside the injection tube 2 can prevent the injection liquid from solidifying inside the tube, avoiding equipment downtime for cleaning due to solidification of the injection liquid, reducing equipment downtime, and further improving equipment utilization. The coolant uniformly cools the injection molded parts through the cooling pipe 35, avoiding problems such as deformation, cracking, or excessive internal stress caused by uneven cooling, thereby improving the dimensional accuracy and appearance quality of the product. The heating process reduces waste caused by poor cooling or solidification of the injection liquid, thereby reducing material waste and waste disposal costs. Rapid cooling reduces the time the mold spends at high temperatures, reducing the risk of mold damage due to thermal fatigue, thus extending the mold's service life and reducing mold replacement costs. Temperature sensor 37 monitors the temperature of the injection molded part in real time during the cooling process, ensuring that demolding is only performed after the appropriate temperature has been reached, avoiding problems caused by insufficient or excessive cooling, and improving the stability and repeatability of the equipment. The coordinated work of heating block 21 and cooling system reduces the risk of equipment failure due to high temperature or solidification of coolant, improving the reliability and service life of the equipment.

[0027] In some embodiments, please refer to the following: Figures 3 to 5The lower mold 13 is provided with a locking assembly 4, which includes a baffle 41, a rotating handle 42, a spring 43, a push rod 44, and a lock cylinder 45. The lower mold 13 has a limit groove, the baffle 41 is set on the lower mold 13 through the limit groove, the push rod 44 is movably set on the baffle 41, one end of the spring 43 abuts against the baffle 41, and the other end of the spring 43 abuts against the push rod 44. The lock cylinder 45 is set on the end of the push rod 44 near the upper mold 11. The upper mold 11 has a lock cylinder 45. The lower mold 13 is provided with a positioning post 5, the upper mold 11 has a positioning groove 51, a through hole 52, and a vent hole 6.

[0028] With this configuration, when using the injection molding equipment, the upper mold 11 and the lower mold 13 are aligned and connected together by the positioning pin 5 and the positioning groove 51. The through hole 52 is used to expel the gas generated when the positioning pin 5 and the positioning groove 51 are combined. At the same time, the operator pushes the rotating handle 42 to compress the spring 43 of the push rod 44, thereby pushing the locking core 45 on the push rod 44 into the locking hole 46. Rotating the rotating handle 42 causes the locking core 45 to rotate in the locking hole 46, thereby locking the upper mold 11 and the lower mold 13. When the operator injects the product through the injection tube 2, the molten material enters the upper mold cavity 12 and the lower mold cavity 14 through the injection tube 2. The molten material compresses the air in the upper mold cavity 12 and the lower mold cavity 14, and the pressure in the upper mold cavity 12 and the lower mold cavity 14 increases, causing the gas to be discharged from the exhaust hole 6. Thus, through the precise cooperation of the positioning pin 5 and the positioning groove 51, the upper mold 11 and the lower mold 13 can be quickly and accurately aligned during mold closing. This design reduces the time and error of manual mold adjustment, improves the alignment accuracy of the mold, and thus ensures the dimensional accuracy and appearance quality of the injection molded parts. Precise mold alignment can avoid defects in injection molded parts caused by mold misalignment, thereby reducing the scrap rate and improving production efficiency. Good venting design can effectively reduce air bubbles and shrinkage cavities inside the injection molded parts, improve the density and mechanical properties of the product, and improve the appearance quality of the product. By pushing the rotating handle 42, the push rod 44 presses... The spring 43 is compressed and the locking core 45 is pushed into the locking hole 46. The handle 42 is turned so that the locking core 45 rotates in the locking hole 46, thereby firmly locking the upper mold 11 and the lower mold 13. This design ensures the stability of the mold during the injection process and avoids injection defects caused by mold loosening. The cooperation of the positioning pin 5 and the positioning groove 51 and the design of the locking mechanism make the mold closing and locking process faster, reducing the equipment preparation time and downtime. The good venting design ensures that the molten material can fill the mold cavity evenly and avoid the problem of uneven filling caused by gas accumulation, thereby improving the dimensional accuracy and appearance quality of the injection molded parts.

[0029] The implementation principle of a high-quality electronic water pump housing injection molding equipment according to an embodiment of this application is as follows: When using the injection molding equipment, by aligning the upper mold 11 and the lower mold 13, the upper mold 11 and the lower mold 13 are connected together by the positioning pin 5 and the positioning groove 51. The through hole 52 is used to expel the gas generated when the positioning pin 5 and the positioning groove 51 are combined. At the same time, the operator pushes the rotating handle 42 to compress the spring 43 of the push rod 44, thereby pushing the locking core 45 on the push rod 44 into the locking hole 46. Rotating the rotating handle 42 causes the locking core 45 to rotate in the locking hole 46, thereby locking the upper mold 11 and the lower mold 13. At the same time, when the operator injects the product through the injection tube 2, when the molten material enters the upper mold cavity 12 and the lower mold cavity 14 through the injection tube 2, the molten material compresses the air in the upper mold cavity 12 and the lower mold cavity 14. The pressure inside 14 increases, causing gas to be expelled from the vent 6. After injection molding is completed, coolant is added to the connecting hole by opening the connecting cover 36. After injection molding is completed through the injection tube 2 into the upper mold cavity 12 and the lower mold cavity 14 of the upper mold 11 and the lower mold 13, the heating block 21 on the injection tube 2 starts working simultaneously to reduce the problem of solidification of the injection liquid in the injection tube 2, which could cause damage to the injection molded parts. The coolant in the water tank 32 is transferred to the water pump 33 through the water pipe 34. The water pump 33 then transfers the coolant to the cooling pipe 35 in the cooling box 31. The water pump 33 continuously circulates the liquid in the cooling pipe 35, cooling the injection molded parts and accelerating the cooling and molding speed of the injection molded parts. When the temperature reaches a certain level, the injection molded parts are formed, and the temperature sensor 37 works to demold the injection molded parts, thereby increasing work efficiency and reducing production losses.

[0030] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
