[0001] This utility model relates to the field of filter element injection mold technology, and in particular to an automotive filter element injection molding device. Background Technology

[0002] In the modern automotive manufacturing industry, automotive filters are key filtration components, and their quality and production efficiency directly affect the performance and cost of the entire vehicle. In order to significantly improve the production efficiency of filters, promote the rapid molding of automotive filters, and improve the production efficiency and quality control level of filters, an automotive filter injection molding device is needed.

[0003] A search revealed Chinese patent publication number CN221809550U, entitled "A Filter Cap Injection Molding Device."

[0004] The technical solution includes: a fixed mold body, a movable mold body connected to the top of the fixed mold body, bottom plates fixedly installed on the bottom of both sides of the outer wall of the fixed mold body, top plates fixedly installed on the top of both sides of the outer wall of the movable mold body, and also includes a clamping plate; the clamping plate is located on the opposite side of the fixed mold body and the movable mold body.

[0005] Among them, a second push plate is movably installed at the bottom of the moving mold body above the clamping plate; among them, the fixed mold body below the clamping plate...

[0006] A first push plate is movably mounted on the top of the mold body. This invention solves the problem of low production efficiency in existing devices.

[0007] Traditional automotive filter injection molding devices have certain limitations in cooling circulation systems, mainly manifested in complex cooling channel design, uneven cooling medium flow rate, and low cooling efficiency. These problems not only prolong the molding cycle of the filter element, but may also lead to internal stress concentration, deformation, or even cracking, seriously affecting the reliability and service life of the filter element. Utility Model Content

[0008] To overcome the above shortcomings, this utility model provides an automotive filter injection molding device, which aims to improve the problems of uneven cooling medium flow rate and unsatisfactory cooling effect in traditional automotive filter injection molding devices.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] An automotive filter element injection molding device includes a base frame, a cooling fan fixedly connected inside the base frame, a lower mold slidably connected inside the base frame, a protective shell fixedly connected to the inner wall of the base frame, a water tank fixedly connected inside the protective shell, a water pump fixedly connected inside the water tank, a water supply pipe fixedly connected to the output end of the water pump, the outer wall of the water supply pipe fixedly connected to the inside of the protective shell, cooling fins, a fixing frame, and a filter box fixedly connected to the outer wall of the water supply pipe, the outer wall of the cooling fins fixedly connected to the inside of the fixing frame, the outer wall of the fixing frame fixedly connected to the outer wall of the protective shell and the inner wall of the base frame, the outer wall of the filter box fixedly connected to the inside of the water tank, and a molding component provided on the outer wall of the lower mold for assisting filter element molding.

[0011] Through the above technical solution, unnecessary branches and dead corners in the water supply pipe are eliminated, allowing the cooling medium to flow more smoothly, reducing flow resistance and energy loss. At the same time, it ensures that the flow rate of the cooling medium is consistent in different areas, avoiding local overheating or overcooling, thereby improving the overall performance and stability of the cooling system, enhancing the cooling effect on filter element injection molding, and promoting the rapid molding of automotive filter elements.

[0012] As a further description of the above technical solution:

[0013] The molding component includes a top frame, the outer wall of which is slidably connected to the outer wall of the lower mold, and an upper mold fixedly connected inside the top frame. The outer wall of the top frame is in contact with the outer wall of the bottom frame, and the outer wall of the upper mold is in contact with the outer wall of the lower mold.

[0014] The above technical solution allows for the formation of a complete injection mold cavity through the cooperation of the upper and lower molds, which is used for the molding of injection molded filter elements, thereby meeting different processing requirements.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the top frame is fixedly connected to a first fixing block, and the inside of the first fixing block is fixedly connected to a first connecting cylinder.

[0017] The above technical solution provides a solution where the top frame supports and fixes the first fixing block, and the first fixing block supports and limits the first connecting cylinder. Through the connection of the first fixing block, the first connecting cylinder can be made more stable during movement.

[0018] As a further description of the above technical solution:

[0019] A positioning rod is slidably connected inside the first connecting cylinder, and a first telescopic rod is fixedly connected to the top end of the positioning rod. A first spring is slidably connected to the outer wall of the first telescopic rod, and the outer wall of the first spring is slidably connected to the inner wall of the first connecting cylinder.

[0020] Through the above technical solution: the first connecting cylinder serves as the support and guide structure for the positioning rod, thereby ensuring that the positioning rod can slide along a predetermined path when subjected to external force, wherein the first connecting cylinder and the first telescopic rod together play the role of limiting the first spring.

[0021] As a further description of the above technical solution:

[0022] The outer wall of the positioning rod is slidably connected to a positioning block, and the outer wall of the positioning block is slidably connected to a second connecting cylinder.

[0023] The above technical solution involves a first connecting cylinder that supports and limits the positioning block, which in turn connects with the positioning rod to jointly undertake the task of mold docking. The positioning block possesses a certain degree of elasticity and wear resistance, allowing it to withstand the compressive force from the positioning rod and wear from prolonged use.

[0024] As a further description of the above technical solution:

[0025] A second fixing block is fixedly connected to the outer wall of the second connecting cylinder, and the upper surface of the second fixing block is in contact with the lower surface of the first fixing block.

[0026] Through the above technical solution: the second fixing block plays the role of supporting and fixing the second connecting cylinder, while the first fixing block and the second fixing block also play the role of assisting the upper mold and the lower mold to connect, thereby making the upper mold and the lower mold connect more neatly.

[0027] As a further description of the above technical solution:

[0028] The outer wall of the second fixing block is fixedly connected to the outer wall of the bottom frame, and the lower surface of the positioning block is fixedly connected to the second telescopic rod.

[0029] The above technical solution provides an auxiliary support for the positioning block, and the telescopic performance of the second telescopic rod also ensures the stability of the positioning block during the sliding process.

[0030] As a further description of the above technical solution:

[0031] The outer wall of the second telescopic rod is slidably connected to a second spring, and the outer wall of the second spring is slidably connected to the inner wall of the second connecting cylinder.

[0032] The above technical solution involves the second spring storing energy when the positioning block compresses the second telescopic rod. When the external force disappears, the rebound force of the second spring causes the positioning block to quickly return to its original position, firmly engaging with the positioning rod. The stiffness and rebound performance of the second spring are also crucial to the stability and accuracy of the mold engagement.

[0033] This utility model has the following beneficial effects:

[0034] 1. In this utility model, the rotation of the cooling fan increases the airflow in the bottom frame, and the water pump delivers the coolant in the water tank to the water pipe. After passing through the cooling fins, the coolant circulates once in the water pipe and then flows back into the water tank after being filtered by the filter box. This improves the cooling effect on the injection molding of the filter element and promotes the rapid molding of the automotive filter element.

[0035] 2. In this utility model, by lowering the top frame, the positioning rod presses against the positioning block. Under the reaction force, the positioning rod slides in the first connecting cylinder, and the positioning block slides in the second connecting cylinder, while simultaneously pressing the first spring and the second spring. Under the rebound of the first spring and the second spring, the positioning rod and the positioning block can be firmly connected, thereby improving the fit between the upper mold and the lower mold.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of an automotive filter element injection molding device, comprising a base frame 1, a cooling fan 2 fixedly connected inside the base frame 1, a lower mold 3 slidably connected inside the base frame 1, a protective shell 4 fixedly connected to the inner wall of the base frame 1, a water tank 5 fixedly connected inside the protective shell 4, a water pump 6 fixedly connected inside the water tank 5, a water supply pipe 7 fixedly connected to the output end of the water pump 6, the outer wall of the water supply pipe 7 fixedly connected to the inside of the protective shell 4, a cooling fin 8, a fixing frame 9, and a filter box 10 fixedly connected to the outer wall of the water supply pipe 7, the outer wall of the cooling fin 8 fixedly connected to the inside of the fixing frame 9, the outer wall of the fixing frame 9 fixedly connected to the outer wall of the protective shell 4 and the inner wall of the base frame 1, the outer wall of the filter box 10 fixedly connected to the inside of the water tank 5, and a molding component 11 provided on the outer wall of the lower mold 3 for assisting in filter element molding.

[0044] Specifically, the cooling fan 2 generates airflow, which increases the airflow within the base frame 1, thus helping to dissipate heat inside the device and preventing excessive temperature from affecting the injection molding effect and the device's lifespan. The water supply pipe 7 uses a straight path and rounded corners to avoid eddies and stagnation of the cooling medium in the flow channel, improving cooling efficiency and allowing the cooling medium to flow more smoothly, reducing flow resistance and energy loss. Simultaneously, the water pump 6 transports the coolant from the water tank 5 to the water supply pipe 7. Under the action of the heat dissipation fins 8, the coolant circulates once in the water supply pipe 7 and then flows back into the water tank 5 after being filtered by the filter box 10. The water tank 5 serves as the main storage container for the coolant, providing a stable coolant supply for the entire cooling system. The heat dissipation fins 8 increase the heat dissipation area and improve heat dissipation efficiency. When the coolant flows through the heat dissipation fins 8, the fins absorb and dissipate heat from the coolant, thereby lowering the coolant temperature. The filter box 10 filters the coolant, removing impurities, particles, and deposits. These impurities may clog the water supply pipe 7, affect the flow and heat dissipation of the coolant, and even damage the injection mold and injection parts. The filtration function of the filter box 10 ensures that the coolant remains clean and pure, thereby improving the overall performance and stability of the cooling system.

[0045] Reference Figure 2The molding component 11 includes a top frame 1101, the outer wall of the top frame 1101 is slidably connected to the outer wall of the lower mold 3, the upper mold 1102 is fixedly connected inside the top frame 1101, the outer wall of the top frame 1101 is in contact with the outer wall of the bottom frame 1, and the outer wall of the upper mold 1102 is in contact with the outer wall of the lower mold 3.

[0046] Specifically, when the upper mold 1102 and the lower mold 3 are connected, the top frame 1101 will slide on the outer wall of the lower mold 3, and at the same time play the role of limiting the lower mold 3. The lower mold 3 can be removed from the bottom frame 1 and can be replaced as needed. Through the cooperation of the upper mold 1102 and the lower mold 3, a complete injection mold cavity can be formed for the molding of injection molded filter elements, thereby meeting different processing requirements.

[0047] Reference Figure 2 and Figure 4 The outer wall of the top frame 1101 is fixedly connected to a first fixing block 13, and the inner wall of the first fixing block 13 is fixedly connected to a first connecting cylinder 14; the inner wall of the first connecting cylinder 14 is slidably connected to a positioning rod 15, the top end of the positioning rod 15 is fixedly connected to a first telescopic rod 16, the outer wall of the first telescopic rod 16 is slidably connected to a first spring 17, and the outer wall of the first spring 17 is slidably connected to the inner wall of the first connecting cylinder 14.

[0048] Specifically, when the positioning rod 15 in the first connecting cylinder 14 is aligned with the positioning block 18, the positioning rod 15 will press against the positioning block 18 during the downward movement of the top frame 1101. Under the reaction force, the positioning rod 15 will slide in the first connecting cylinder 14. The first connecting cylinder 14 serves to support and limit the positioning rod 15, and at the same time, it serves to press against the first telescopic rod 16 and compress the first spring 17. The first telescopic rod 16 serves to support and limit the first spring 17, increasing the service life of the first spring 17. When the pressure of the first spring 17 is released, the rebound of the first spring 17 will push the first telescopic rod 16 and the positioning rod 15 to reset, ensuring that the positioning rod 15 is tightly connected with the positioning block 18.

[0049] Reference Figure 3 and Figure 4 A positioning block 18 is slidably connected to the outer wall of the positioning rod 15, and a second connecting cylinder 19 is slidably connected to the outer wall of the positioning block 18; a second fixing block 20 is fixedly connected to the outer wall of the second connecting cylinder 19, and the upper surface of the second fixing block 20 is in contact with the lower surface of the first fixing block 13; the outer wall of the second fixing block 20 is fixedly connected to the outer wall of the bottom frame 1, and a second telescopic rod 21 is fixedly connected to the lower surface of the positioning block 18; a second spring 22 is slidably connected to the outer wall of the second telescopic rod 21, and the outer wall of the second spring 22 is slidably connected to the inner wall of the second connecting cylinder 19.

[0050] Specifically, when the positioning block 18 slides in the second connecting cylinder 19, it simultaneously squeezes the second telescopic rod 21 and compresses the second spring 22. Under the rebound action of the first spring 17 and the second spring 22, the positioning rod 15 and the positioning block 18 are firmly connected. The second telescopic rod 21 supports and limits the second spring 22. The positioning block 18 is provided with a groove to increase the accuracy of the connection with the positioning rod 15. The second connecting cylinder 19 supports and limits the positioning block 18.

[0051] Working principle: When this device is needed, the raw material is first added to the lower mold 3, and then the upper mold 1102 is covered on the lower mold 3 by the top frame 1101. At this time, the top frame 1101 will drive the positioning rod 15 in the first connecting cylinder 14 to engage with the positioning block 18 through the first fixing block 13. During the downward movement of the top frame 1101, the positioning rod 15 will squeeze the positioning block 18. Under the reaction force, the positioning rod 15 will slide in the first connecting cylinder 14, while squeezing the first telescopic rod 16 and compressing the first spring 17. The corresponding positioning block 18 will slide in the second connecting cylinder 19, while squeezing the second telescopic rod 21 and compressing the second spring 22. Under the rebound of the first spring 17 and the second spring 22, the positioning rod 15 and the positioning block 18 can be firmly connected, thereby improving the fit between the upper mold 1102 and the lower mold 3.

[0052] Then, heating the lower mold 3 and the upper mold 1102 completes the forming process of the filter element. At this time, the water pump 6 starts to work, and the water pump 6 can deliver the coolant in the water tank 5 to the water supply pipe 7. Under the action of the heat dissipation fins 8, the coolant circulates once in the water supply pipe 7 and then flows back into the water tank 5 after being filtered by the filter box 10. At the same time, the rotation of the cooling fan 2 increases the air flow in the bottom frame 1, thereby rapidly cooling the lower mold 3.

[0053] This device not only improves the fit between the upper mold 1102 and the lower mold 3, but also reduces the gap between the molds, avoiding defects such as burrs and flash caused by the gap. It also ensures the stability of the injection molded parts' dimensions, improves the product's precision and consistency, and meets the stringent dimensional accuracy requirements of automotive filter elements.

[0054] It also improves the cooling effect of filter element injection molding, promotes the rapid molding of automotive filter elements, and can quickly remove heat from the injection molded parts, accelerate the resin curing process, thereby shortening the product molding cycle and improving production efficiency.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
