Description

Technical Field

[0001] This invention relates to an improved invention of an automotive oil filter housing assembly and its casting mold. Background Technology

[0002] The automotive oil filter is located in the engine lubrication system. Its function is to filter out harmful impurities from the oil in the oil pan and supply the filtered oil to moving parts such as the crankshaft, thereby providing lubrication, cooling, and cleaning, and extending the life of these components.

[0003] Oil filters are primarily made of plastic, which offers advantages such as light weight and low processing costs. However, plastic also presents challenges due to the welded joints of oil and water holes, making them prone to leakage. Once a leak occurs, the entire filter must be replaced, resulting in a short lifespan and high maintenance costs. Furthermore, the radiator outlet and the filter housing outlet are horizontally offset and connected by a connector. This means the filter housing assembly consists of two parts, increasing both the processing steps and costs, as well as the likelihood of leaks and maintenance costs. Summary of the Invention

[0004] In view of the technical problems existing in the background art, the technical problem to be solved by the present invention is to provide an automotive oil filter housing assembly and its casting mold that has a long service life, is not easy to leak and has low maintenance cost.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the automotive oil filter housing assembly is characterized in that it includes a base, which is a rectangular metal casting.

[0006] One end of the base is connected to a filter element housing, the filter element housing is obliquely upward relative to the base and the two are integrated, the bottom of the filter element housing is provided with an oil inlet port communicating with the inner cavity of the filter element housing, and the filter element housing is provided with a central hole.

[0007] The other end face of the base is provided with a water inlet;

[0008] The base is provided with a longitudinal and horizontally arranged straight oil passage. One end of the straight oil passage extends to the central hole and the two are connected. The other end of the straight oil passage extends longitudinally to the side end face of the base. An oil outlet is connected to the straight oil passage and extends downward to the lower surface of the base.

[0009] The base is also provided with a horizontally arranged first water channel and a second water channel.

[0012] This invention utilizes a one-piece metal casting process, resulting in high strength, durability, and a long service life. The mounting surface of the base is used to install the radiator. Cooling water enters through the inlet, flows into the radiator via water hole two, is cooled by the radiator, then flows into water hole one, and finally exits through the first and second water outlets. Similarly, engine oil is filtered by a filter and enters the straight oil path. A portion of the oil enters the radiator through oil hole two, is cooled by the radiator, and then flows into oil hole one, exiting through the oil outlet. Water hole one on the base connects to the first and second water outlets via the first and second water paths, which are horizontally arranged. Likewise, the straight oil path is horizontally arranged longitudinally. This design of the oil and water paths not only facilitates the entry and exit of engine oil and cooling water but also makes core pulling during casting easier and facilitates casting processing.

[0017] The center of the top, bottom, left, and right sides of the base is recessed inward around the straight oil passage. Oil and water holes are uniformly distributed at both ends of the base, while the middle section of the base, unrestricted by piping, employs a recessed design to reduce metal usage, lower costs, and reduce product weight.

[0027] The casting mold for the automotive oil filter housing assembly includes:

[0028] The casting mold for the automotive oil filter housing assembly includes:

[0036] The moving mold and the fixed mold are combined. The moving mold and the fixed mold are provided with left notch, right notch, front notch, rear notch and filter mold hole respectively matching the left mold, right mold, upper mold, lower mold and filter mold. The left mold and right mold move left and right to enter and exit the left notch and right notch respectively. The upper mold and lower mold move back and forth to enter and exit the front notch and rear notch respectively. The filter mold moves obliquely to enter and exit the filter mold hole. The moving mold, fixed mold, left mold, right mold, upper mold, lower mold and filter mold form the base cavity.

[0037] The moving mold is further provided with a first water channel core hole and a second water channel core hole that match the first water channel core and the second water channel core. The first water channel core and the second water channel core are respectively matched with the first water channel and the second water channel. The first water channel core and the second water channel core are respectively connected to a first driving component and a second driving component that drive them to move in the corresponding core hole. The first driving component and the second driving component are mounted on the moving mold base.

[0038] The left mold is provided with an oil passage core that matches the oil passage and an inner hole core that matches the inner hole of the water inlet.

[0058] The following description, in conjunction with the accompanying drawings, details the embodiments and working principles of the present invention. In the figures, the X-axis represents the left-right direction, the Y-axis represents the front-back direction, and the Z-axis represents the up-down direction.

[0059] This type of automotive oil filter housing assembly includes a base 1, which is a rectangular cast metal base. One end of the base is connected to a filter housing 2, which is angled upwards relative to the base and the two are integrally formed. The bottom of the filter housing 2 has an oil inlet 17 communicating with the inner cavity of the filter housing. The filter housing has a central hole 18, and the filter element is installed inside the filter housing. The filter housing is threadedly connected to a filter cover. A water inlet 5 is provided on the other end face of the base 1, and the water inlet is perpendicular to the side end of the base 1. The base has a longitudinally and horizontally arranged straight oil passage 19. One end of the straight oil passage extends to the central hole 18, and the two are connected. The other end of the straight oil passage extends longitudinally to the side end face of the base, serving as a first sensor mounting port 12. Above the first sensor mounting port is a second sensor mounting port 13, which extends obliquely downward and communicates with the straight oil passage 19. The first sensor mounting port 12 and the second sensor mounting port 13 are used to install a pressure sensor and a temperature sensor, respectively, to detect the pressure and temperature of the oil in the straight oil passage. Both the first and second sensor mounting ports have internal threads, allowing the sensors to be installed using a threaded connection method, ensuring good sealing and preventing damage or leakage. An oil outlet 14 is connected to the straight oil passage, extending downward to the lower surface of the base, from which filtered and cooled oil is discharged.

[0060] The base 1 also includes a horizontally arranged first water channel 8 and a second water channel 9. The first and second water channels are straight and extend to the side of the base, forming a core-pulling sealing port. This core-pulling sealing port has internal threads, and a sealing cap is connected via these threads to seal the core-pulling sealing port left during casting. The threaded connection provides good sealing performance, preventing leakage and damage. One end of the first water channel 8 and the second water channel 9 intersects, and a first water outlet 15 extends from the intersection point to the lower surface of the base. The first water channel also extends to the upper surface of the base with a water hole 7, and the second water channel 9 extends to the lower surface of the base with a second water outlet 16. The upper surface of the base is a mounting surface for mounting the radiator. This mounting surface also includes oil holes 4 and 3 communicating with the straight oil channels, and a water hole 6 communicating with the water inlet. Water holes 7, 6, 4, and 3 connect to the water outlet and inlet of the radiator, respectively. The oil inlet and outlet are corresponding. Cooling water enters through the inlet 5, passes through water hole 2 6 into the radiator, is cooled by the radiator, and then exits through water hole 1 7. The cooling water then passes through the first water passage 8 and the second water passage 9 and exits through the first outlet 15 and the second outlet 16. Similarly, engine oil enters the filter housing 1 through the oil inlet 17, is filtered by the filter element, and enters the straight oil passage 19. Some engine oil enters the radiator through oil hole 2 3, is cooled by the radiator, and then exits through oil hole 1 1, then into the straight oil passage 19, and finally exits through oil hole 14. A first sealing groove 11 is provided around water hole 1, water hole 2, oil hole 1, and oil hole 2 on the upper surface of the base; a second sealing groove 20 is provided around the oil outlet, first water outlet, and second water outlet on the lower surface of the base. During installation, sealing rings are placed in the first and second sealing grooves to ensure sealing and prevent oil and water leakage. The oil inlet, water hole one, water hole two, first water outlet, second water outlet, oil hole one, oil hole two, and oil outlet are all vertically arranged on the base 1; the oil outlet 14 is perpendicular to the straight oil passage 19 and intersects with it. This invention is integrally molded using metal casting, resulting in high strength, durability, and a long service life. The oil and water passage design not only accommodates the inflow and outflow of engine oil and cooling water but also facilitates core pulling during casting. The core moves primarily in a linear fashion, simplifying the casting mold structure, reducing processing costs, and increasing efficiency.

[0061] The oil hole 2 3, water hole 1 7, first water channel 8 and second water channel 9 are located at the end near the valve core seat, and the first water channel and second water channel are obliquely arranged relative to the straight oil channel; the oil hole 1 4, water hole 2 6 and oil outlet hole 14 are located at the other end of the base; the center of the upper and lower surfaces and the left and right surfaces of the base are recessed inward 10 around the straight oil channel. In this invention, the oil holes and water holes are uniformly distributed at both ends of the base, and the middle part of the base is not restricted by the pipeline, leaving only the straight oil channel. The excess part of the base is removed, and the groove design is adopted to reduce the amount of metal used, reduce the cost and product weight.

[0062] A casting mold for an automotive oil filter housing assembly includes a moving mold 31, a fixed mold 32, a left mold 33, a right mold 34, an upper mold 35, a lower mold 36, and a filter mold 37. The moving mold 31 mates with the first side surface 51 of the base and the first side surface of the filter housing; the fixed mold 32 mates with the second side surface 52 of the base and the second side surface of the filter housing; the left mold 33 mates with the first side end face 53 of the base; the right mold 34 mates with the second side end face 54 of the base; and the upper mold 35 mates with... The upper surface 55 of the base fits; the lower mold fits the lower surface of the base; the filter mold 37 matches the inner cavity of the filter housing; the moving mold and the fixed mold are pressed together; the moving mold 31 and the fixed mold 32 are provided with left notches, right notches 38, front notches, rear notches and filter mold holes respectively matching the left mold, right mold, upper mold, lower mold and filter mold; the left mold and right mold 34 move left and right to enter and exit the left notch and right notch 38 respectively, and the upper mold and lower mold move back and forth to enter and exit the front notch and rear notch respectively; the filter mold is inclined. The moving mold 31, which moves in and out of the filter mold holes, is further provided with a first water channel core hole 43 and a second water channel core hole 44 that match the first water channel core 47 and the second water channel core 48. The first water channel core and the second water channel core are respectively matched with the first water channel 8 and the second water channel 9. The first water channel core and the second water channel core are respectively connected to the first driving component 24 and the second driving component 28 that drive them to move in the corresponding core holes, and the first driving component and the second driving component are installed on... On the moving mold base 21; the left mold 33 is provided with an oil passage core 40 matching the oil passage and an inner hole core 39 matching the inner hole of the water inlet; the upper mold 35 is provided with an upper core 41 matching water hole 7, water hole 6, oil hole 4, and oil hole 3; the lower mold is provided with a lower core 42 matching the inner hole of oil outlet 14, first water outlet 15, second water outlet 16, and oil inlet 17; the moving mold, fixed mold, left mold, right mold, upper mold, lower mold, and filter mold form the base cavity. Because the oil passage, oil hole, and water hole on the base are designed with straight lines, the corresponding cores move linearly, thereby simplifying the mold structure. Moreover, the mold is small in size and occupies little space, greatly reducing the mold cost; the linear movement of the core reduces the difficulty of core pulling and extends the service life.

[0063] The fixed mold 32 is mounted on the fixed mold base 22, which has several sliding grooves 29. The left mold, right mold, upper mold, lower mold, and filter mold are mounted on their respective sliders, which slide within the sliding grooves 29. The left mold, right mold, upper mold, lower mold, and filter mold are concentrated on the fixed mold base 22 and move on it. When the moving mold and the fixed mold are separated, the fixed mold base remains stationary, resulting in better stability. The slider includes a limit block 27. The moving mold base has a limiting groove 45 that allows the limit block to move and restricts its travel. The notch 38 on the moving mold and the limiting groove 45 on the moving mold base form a stepped shape. When the mold is closed, the limit block 27 moves toward the moving mold until the moving mold 31 blocks the limit block. When the mold is opened, the limit block moves away from the moving mold until the inner wall 53 of the moving mold base 21 blocks the limit block. The limit block 27 moves within the limiting groove 45, controlling the travel of the mold and improving the stability of mold closing and opening. The moving mold base is provided with guide pillars 47, and the fixed mold base is provided with guide holes 48. The guide pillars and guide holes are matched. The left mold, upper mold, lower mold, and filter mold are respectively connected to the power component 23 that drives their movement. The power component is installed on the fixed mold base 22. The moving mold base is also provided with inclined push pillars 46. The slider of the right mold is provided with inclined push holes 30 for the inclined push pillars to be inserted. The inclined push pillars and inclined push holes are set obliquely to the right. When the mold is opened, the moving mold moves closer to the fixed mold, the guide pillars 47 are inserted into the guide holes 48, and the inclined push pillars 46 are inserted into the inclined push holes 30 and drive the right mold 34 to move to the left. Conversely, when the mold is closed, the moving mold 31 moves away from the fixed mold, the guide pillars gradually leave the guide holes, and the inclined push pillars push the right mold to move to the right until the inclined push pillars leave the inclined push holes. The movement of the moving mold drives the movement of the right mold, saving the driving power for the movement of the right mold.

[0064] The first driving component 51 includes a slide block 50 and a power source 51 that drives the slide block to move left and right on the moving mold base. The slide block is provided with an inclined slide groove 49. The mounting end of the first water channel core 47 is slidably disposed in the inclined slide groove 49. When the power source 51 drives the slide block to move left and right, the slide block moves obliquely through the inclined slide groove 49 during the movement, causing the first water channel core 47 to move within the first water channel core hole 43. In this way, the driving end of the power source moves linearly left and right, which is the same as the movement direction of the left and right molds, and occupies little space. The second driving component 25 adopts the same structure. Due to the different orientations of the first and second water channels, the driving direction of the power source and the orientation of the inclined slide groove are changed accordingly.

[0065] When the mold is opened, the first driving component 24 and the second driving component 25 respectively drive the first water channel core 47 and the second water channel core 48 to exit the first water channel 8 and the second water channel 9 of the molding base 1; the power component 23 drives the left mold 33, the upper mold 35, the lower mold 36, and the filter mold 37 to move to the left, up, down, and diagonally upward along their respective slides, so that the oil channel core 40, the inner hole core 39, the upper core 41, the lower core 42, and the filter mold 37 all exit the molding base 1. Then the moving mold 31 moves forward and away from the fixed mold 32, and drives the right mold 34 to move to the right. Finally, the molding base 1 is removed from the fixed mold 32. When the mold is closed, the moving mold moves towards the fixed mold and drives the right mold to move to the left. The moving mold and the fixed mold close together. The left mold, the upper mold, the lower mold, and the filter mold move towards the cavity along their respective slides. The first driving component and the second driving component drive the first water channel core and the second water channel core to penetrate into the core hole. The automotive oil filter housing assembly of this invention is integrally molded from metal casting, resulting in high strength, durability, and a long service life. The oil and water circuit design not only accommodates the inflow and outflow of engine oil and coolant but also facilitates core pulling during casting. The core moves primarily in a linear fashion, simplifying the casting mold structure and reducing processing costs while increasing efficiency.
