Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive parts manufacturing and die casting, and in particular to an automotive motor housing with a visible glass structure, a die casting mold, and a die casting method. Background Technology
[0002] In the fields of automobile manufacturing, auto repair training, and special industrial vehicles, motor housings with glass viewing windows have long been the core carrier for visually observing motor status. Their application scenarios cover three core areas: First, in teaching and training scenarios in auto repair vocational schools and automotive R&D laboratories, they are used to intuitively display the dynamic processes such as rotor operation, brush wear, and winding temperature rise inside the motor, reducing the threshold for technicians to understand the principles of motor operation; Second, in monitoring motor scenarios for special explosion-proof vehicles and mining vehicles, maintenance personnel can quickly troubleshoot internal jams, foreign object intrusion, and other faults through the viewing window without disassembling the entire machine, greatly improving the efficiency of equipment inspection in high-risk scenarios; Third, in exhibition promotion and product testing scenarios for motor manufacturers, the transparent viewing window intuitively presents the internal winding arrangement and magnet fixing process, showcasing the product's processing precision to customers, while simultaneously observing the wear status of internal components in real time during durability testing.
[0003] In existing technologies, automotive motor housings with glass observation ports generally adopt two mainstream structures: The first type is a fully transparent acrylic integral housing, which is only used in small-power motors for teaching demonstrations. It achieves full-view observation through the overall light transmittance of organic materials, but this type of structure cannot meet the heat dissipation, strength, and protection level requirements of actual vehicle motors, and is completely unsuitable for vehicle installation; The second type is a metal housing with a partial observation window. After the glass is embedded in a reserved groove, it is locked and fixed by a pressure plate and multiple screws. The gap between the glass and the window is filled with sealant to achieve dust and water resistance. This type of structure is currently one of the few mainstream solutions that can be adapted to actual vehicle working conditions, and has been used in a small number of monitoring motors in some special operation vehicles.
[0004] However, this type of screw-locking pressure plate type automotive motor housing with glass observation port has the following drawbacks in actual production and long-term use: 1. When tightening the pressure plate with multiple screws, manual operation can easily result in excessive or insufficient tightening force. If the tightening force is too large, the glass may be squeezed and shattered. If the tightening force is too small, gaps may appear between the glass and the car motor housing. The uncontrollable factors of manual operation are too high, which seriously limits the production yield of the product. 2. When multiple screws are used to tighten the pressure plate, the torque deviation caused by manual operation can easily lead to uneven stress on the glass. Under the high-frequency vibration and alternating hot and cold conditions of a car, local stress concentration in the glass can easily cause it to break. Moreover, the car motor is in a bumpy and vibrating environment for a long time, and the screws can easily loosen slowly. Once the pressure plate is displaced, the originally tightened glass will loosen and shift. At the same time, the sealant layer will gradually crack under the continuous vibration and shear force, allowing moisture and dust to enter the motor, directly causing winding short circuits, bearing corrosion and other faults, which will significantly shorten the service life of the motor. 3. The entire assembly process requires multiple steps, such as glass positioning, sealant application, pressure plate alignment, and step-by-step screw fastening, which involve a lot of manual operation and severely limits production efficiency, making it completely unsuitable for the large-scale mass production needs of the automotive parts industry.
[0005] Therefore, a new technical solution needs to be researched to address the above problems. Summary of the Invention
[0006] In view of this, the present invention addresses the deficiencies of the prior art by providing an automotive motor housing with a visible glass structure, effectively solving the technical defects of low production yield, short service life, and low production efficiency of automotive motor housings with glass viewing ports in the prior art.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: a car motor housing with a visible glass structure, comprising a housing body and a visible glass structure; the housing body is provided with a first chamber, the first chamber penetrating the outer surface of the housing body to form a first opening; characterized in that: the visible glass structure includes tempered glass; The upper pressure ring is located on the upper surface of the tempered glass; The lower pressure ring is located on the lower surface of the tempered glass; when the upper pressure ring and the lower pressure ring are connected together, they can clamp the tempered glass. When the visualization glass is placed into the die-casting mold, the outer shell body can be die-cast and the upper and lower pressure rings can be embedded, thus completing the assembly of the visualization glass and the outer shell body.
[0008] As a preferred embodiment: the inner bottom of the upper pressure ring is provided with an upper notch, and the inner top of the lower pressure ring is provided with a lower notch; When the upper and lower pressure rings are assembled together, the upper and lower notches can form an assembly groove, and the edge of the tempered glass can be inserted into the assembly groove.
[0009] As a preferred embodiment: a first gap is formed between the upper surface of the tempered glass and the upper surface of the upper notch, and a second gap is formed between the lower surface of the tempered glass and the lower surface of the lower notch; Both the first gap and the second gap are provided with sealing gaskets, and the thickness of the sealing gaskets in the vertical direction is greater than the thickness of the first gap and the second gap in the vertical direction.
[0010] As a preferred embodiment: the upper surface of the upper pressure ring is provided with a first inclined surface, which is inclined downward from the inside to the outside; the lower surface of the lower pressure ring is provided with a second inclined surface, which is inclined upward from the inside to the outside. Both the first inclined surface and the second inclined surface are provided with a plurality of first embedding grooves, and the first embedding grooves are spaced apart from the inside to the outside.
[0011] As a preferred embodiment: the upper pressure ring is provided with a first rivet hole, which penetrates the upper and lower surfaces of the upper pressure ring; The lower pressure ring is provided with a second rivet hole, which penetrates the upper surface of the lower pressure ring; when the upper pressure ring and the lower pressure ring are assembled together, the upper pressure ring and the lower pressure ring can be fixed by inserting the first rivet post into the second rivet hole through the first rivet hole.
[0012] As a preferred embodiment: The inner side of the upper pressure ring is provided with a first abutting inclined surface, which is inclined outward from bottom to top; The inner side of the pressure ring is provided with a second abutting slope, which is inclined from top to bottom and outward.
[0013] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution: 1. By setting up an upper and lower pressure ring structure, when the outer shell body is die-cast, the upper and lower pressure rings can be embedded in the metal of the outer shell body to complete the fixation. Compared with the traditional method of using screws for fixing, it can ensure that the tightening force is not too large or too small, thereby improving the production yield of the product; and it will not loosen, thereby further improving the service life of the product. 2. The visible glass structure is inserted into the die-casting mold, and the outer shell body is formed by die-casting. The metal part of the outer shell body covers the outer surfaces of the upper and lower pressure rings, thereby completing the assembly of the visible glass structure and the outer shell body. No manual assembly is required, which greatly improves the production efficiency of the visible glass structure and the outer shell body, and is especially suitable for the large-scale mass production needs of the automotive parts industry.
[0014] To achieve the above objectives, the present invention also employs the following technical solution: a die-casting mold for an automotive motor housing with a visible glass structure, used for die-casting the aforementioned automotive motor housing with a visible glass structure, wherein the die-casting mold includes... The lower mold base has a lower mold core at the top, and a first lower punch is provided at the top of the lower mold core; The upper mold base is movable up and down and installed on the top of the lower mold base; the bottom of the upper mold base is provided with an upper mold core, and the bottom of the upper mold core is provided with a first upper punch; when the upper mold base and the lower mold base are closed, they can form a molding cavity for injection molding the outer shell body, and the first cavity and the first opening are injection molded through the first upper punch and the first lower punch. The first lower punch has a first mounting protrusion at its top and a second mounting protrusion at its bottom. After the upper mold base and the lower mold base are opened, the lower pressure ring of the visible glass structure is aligned with the first mounting protrusion, and the side of the first mounting protrusion abuts against the second abutting slope; the upper mold base can then close with the lower mold base, so that the second mounting protrusion abuts against the first abutting slope.
[0015] As a preferred embodiment: after the upper mold base and the lower mold base are closed, the distance between the top of the first mounting protrusion and the lower surface of the tempered glass is set, and the distance between the bottom of the second mounting protrusion and the upper surface of the tempered glass is set.
[0016] As a preferred embodiment: the upper mold base is provided with a pouring gate at its front end, and the pouring gate is connected to the front end of the molding chamber through a first flow channel; The upper mold base and the lower mold base are provided with exhaust channels at their rear ends, and the exhaust channels are connected to the rear end of the molding chamber.
[0017] Compared with the prior art, the present invention has significant advantages and beneficial effects. Specifically, as can be seen from the above technical solution: a first lower punch is provided at the top of the lower mold core, a first upper punch is provided at the bottom of the upper mold core, and the top of the first lower punch is provided with a first mounting protrusion, while the first upper punch is provided with a second mounting protrusion; when the upper mold base and the lower mold base are opened, the pressure ring of the visible glass structure is aligned with the first mounting protrusion, and the side of the first mounting protrusion abuts against the second abutting inclined surface; the upper mold base can then close with the lower mold base, causing the second mounting protrusion to abut against the first abutting inclined surface, thus... The outer surfaces of both the upper and lower pressure rings are located within the molding chamber and can seal the tempered glass. During die casting, the aluminum alloy slurry enters the molding chamber and can be die-cast to form the outer shell body, covering the outer surfaces of the upper and lower pressure rings without entering the tempered glass area. This allows the upper and lower pressure rings to be embedded in the metal of the outer shell body for fixation. This structure eliminates the need for applying adhesive and then pressing the tempered glass, as well as the need for screws to secure the tempered glass. This not only improves product yield but also extends service life and increases production efficiency. At the same time, after the upper mold base and the lower mold base are closed, the installation tightness between the upper pressure ring and the lower pressure ring can be further adjusted, thereby further improving the sealing performance between the upper pressure ring and the lower pressure ring and the tempered glass, thus improving the production yield of the product.
[0018] To achieve the above objectives, the present invention also employs the following technical solution: a die-casting method for an automotive motor housing having a visible glass structure, applied to a die-casting mold for the automotive motor housing having a visible glass structure, wherein the die-casting method includes... Step 1: Provide a die casting machine, install the lower mold base on the fixed worktable of the die casting machine, and install the upper mold base on the movable worktable of the die casting machine. The movable worktable moves up and down in linkage with the push rod system, so that the upper mold base can move up to open the mold or move down to close the mold relative to the lower mold base. Step 2: Drive the upper mold base to move upward relative to the lower mold base to open the mold, and then provide the visible glass structure; align the lower pressure ring of the visible glass structure with the first mounting protrusion, and make the lower pressure ring bear on the first mounting protrusion, so that the outer surface of the first mounting protrusion abuts against the second abutting inclined surface to reach the final loading state; Step 3: Drive the upper mold base to move down relative to the lower mold base to close the mold. When the upper mold base and the lower mold base are closed in place, the side of the second mounting protrusion can abut against the second abutting inclined surface, and the upper pressure ring and the lower pressure ring are squeezed tightly again through the mold closing position of the first lower punch and the first upper punch. Step 4: Provide aluminum alloy slurry, which enters from the pouring port and flows through the first runner into the molding chamber; Step 5: After the aluminum alloy slurry completely fills the molding chamber, the aluminum alloy slurry can flow from the rear end of the molding chamber into the exhaust channel; and after waiting 60S-130S for cooling and solidification, it forms an outer shell body that can cover the outer surfaces of the upper and lower pressure rings. Step 6: Drive the upper mold base to move upward relative to the lower mold base to open the mold, which can demold the upper mold core and the first upper punch; and drive the ejector plate of the lower mold base to move upward, so that multiple ejector pins can extend from the surface of the lower mold core through the linkage of the ejector plate, so as to eject the outer shell body from the lower mold core and the first lower punch and unload it. Step 7: Repeat steps 2 to 6 to continuously die-cast the car motor housing with a visible glass structure. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0027] Please refer to the following: Figures 1 to 5 The present application will now describe the automotive motor housing 10 with a visible glass structure 12 provided in the embodiments of this application. The automotive motor housing 10 with a visible glass structure 12 includes a housing body 11 and a visible glass structure 12.
[0028] The outer shell body 11 is provided with a first chamber 111, which penetrates the outer surface of the outer shell body 11 to form a first opening 112; the visible glass structure 12 includes tempered glass 123, an upper pressure ring 121 and a lower pressure ring 122; the upper pressure ring 121 is disposed on the upper surface of the tempered glass 123 and the lower pressure ring 122 is disposed on the lower surface of the tempered glass 123; when the upper pressure ring 121 and the lower pressure ring 122 are connected together, they can clamp the tempered glass 123; when the visible glass is placed into the die-casting mold 20, the outer shell body 11 can be die-cast by the die-casting mold 20 and the upper pressure ring 121 and the lower pressure ring 122 can be embedded, thus completing the assembly of the visible glass and the outer shell body 11.
[0029] Specifically, by setting the structure of the upper pressure ring 121 and the lower pressure ring 122, when the outer shell body 11 is die-cast, the upper pressure ring 121 and the lower pressure ring 122 can be embedded into the metal of the outer shell body 11 to complete the fixation. Compared with the traditional method of using screws for fixing, it can ensure that the tightening force is not too large or too small, thereby improving the production yield of the product; and it will not loosen, thereby further improving the service life of the product; at the same time, compared with the traditional method of using adhesive bonding and pressing, it will not cause damage due to high temperature. This prevents the tempered glass 123 from falling off, thereby further extending the product's lifespan. Simultaneously, by inserting the visible glass structure 12 into the die-casting mold 20, the outer shell body 11 can be die-cast using the die-casting mold 20. The metal part of the outer shell body 11 is then used to cover the outer surfaces of the upper pressure ring 121 and the lower pressure ring 122, thus completing the assembly of the visible glass structure 12 and the outer shell body 11. This eliminates the need for manual assembly, significantly improving the production efficiency of the visible glass structure 12 and the outer shell body 11, making it particularly suitable for the large-scale mass production needs of the automotive parts industry.
[0030] In some embodiments of this application, the upper pressure ring 121 has an upper notch 1241 at its inner bottom, and the lower pressure ring 122 has a lower notch 1242 at its inner top. When the upper pressure ring 121 and the lower pressure ring 122 are assembled together, the upper notch 1241 and the lower notch 1242 can form an assembly groove 124, and the edge of the tempered glass 123 can be inserted into the assembly groove 124. This structure can limit the specific installation position of the tempered glass 123 through the assembly groove 124, preventing the tempered glass 123 from being installed incorrectly, reducing the assembly difficulty for operators, and improving the reliability of production operations.
[0031] Specifically, a first gap is formed between the upper surface of the tempered glass 123 and the upper surface of the upper notch 1241, and a second gap is formed between the lower surface of the tempered glass 123 and the lower surface of the lower notch 1242. A sealing gasket 125 is provided in both the first and second gaps, and the thickness of the sealing gasket 125 in the vertical direction is greater than the thickness of the first and second gaps in the vertical direction. The upper surface of the upper pressure ring 121 has a first inclined surface 1211, which is inclined downwards from the inside out. The lower surface of the lower pressure ring 122 has a second inclined surface 1221, which is inclined upwards from the inside out. Both the first and second inclined surfaces 1211 and 1221 have multiple first embedding grooves 1212, which are spaced apart from the inside out. This structure allows the metal of the outer casing 11 to be embedded in the first embedding grooves 1212, thereby improving the connection strength between the upper pressure ring 121, the lower pressure ring 122, and the outer casing 11.
[0032] More specifically, the upper pressure ring 121 is provided with a first rivet hole 1213, which penetrates the upper and lower surfaces of the upper pressure ring 121; the lower pressure ring 122 is provided with a second rivet hole 1222, which penetrates the upper surface of the lower pressure ring 122; when the upper pressure ring 121 and the lower pressure ring 122 are assembled together, the upper pressure ring 121 and the lower pressure ring 122 can be fixed by inserting a first rivet 1223 into the second rivet hole 1222 through the first rivet hole 1213. The inner side of the upper pressure ring 121 is provided with a first abutting inclined surface 1214, which is inclined from bottom to top and outward; the inner side of the lower pressure ring 122 is provided with a second abutting inclined surface 1224, which is inclined from top to bottom and outward.
[0033] For example, when assembling the visible glass structure 12, firstly, a lower pressure ring 122 is taken and the lower notch 1242 of the lower pressure ring 122 is set facing upward; then, a sealing gasket 125 is installed in the lower notch 1242, and then the tempered glass 123 is installed in the lower notch 1242; next, an upper pressure ring 121 is taken, a sealing gasket 125 is installed in the upper notch 1241 of the upper pressure ring 121 and the upper notch 1241 is set facing downward, so that the upper pressure ring 121 and the lower pressure ring 122 are assembled together; finally, the first rivet 1223 is inserted into the second rivet hole 1222 through the first rivet hole 1213 to complete the fixing of the upper pressure ring 121 and the lower pressure ring 122.
[0034] It should be noted that the upper pressure ring 121 and the lower pressure ring 122 may not be fully assembled in this assembled state, but they can remain in place. Subsequently, the upper mold base 22 and the lower mold base 21 of the die-casting mold 20 can be closed to ensure that the upper pressure ring 121 and the lower pressure ring 122 are installed in place, so that the sealing gasket 125 can seal the gap between the tempered glass 123 and the upper pressure ring 121 and the lower pressure ring 122.
[0035] Please refer to the following: Figures 6 to 10 In other embodiments of this application, a die-casting mold 20 for an automotive motor housing 10 having a visible glass structure 12 is also provided. The die-casting mold 20 is used to die-cast the automotive motor housing 10 having the visible glass structure 12.
[0036] Specifically, the die-casting mold 20 includes a lower mold base 21 and an upper mold base 22; the lower mold base 21 has a lower mold core 211 at its top, and a first lower punch 212 at its top; the upper mold base 22 is movably mounted on the top of the lower mold base 21; the upper mold base 22 has an upper mold core 221 at its bottom, and a first upper punch 222 at its bottom; when the upper mold base 22 and the lower mold base 21 are closed, they can form a molding chamber 23 for injection molding the outer shell body 11, and injection molding is performed through the first upper punch 222 and the first lower punch 212. The first chamber 111 and the first opening 112 are formed. The top of the first lower punch 212 is provided with a first mounting protrusion 213, and the bottom of the first upper punch 222 is provided with a second mounting protrusion 223. After the upper mold base 22 and the lower mold base 21 are opened, the lower pressure ring 122 of the visible glass structure 12 is aligned with the first mounting protrusion 213, and the side of the first mounting protrusion 213 abuts against the second abutting inclined surface 1224. The upper mold base 22 can close with the lower mold base 21, so that the second mounting protrusion 223 abuts against the first abutting inclined surface 1214. With this structure, the specific positions of the upper pressure ring 121 and the lower pressure ring 122 can be maintained by the first mounting part and the second mounting part, thereby ensuring that the die casting process can be carried out reliably. Moreover, it can ensure that the metal slurry will not enter the tempered glass 123 position from the gap inside the upper pressure ring 121 and the lower pressure ring 122, thereby improving the production yield.
[0037] Preferably, after the upper mold base 22 and the lower mold base 21 are closed, the distance between the top of the first mounting protrusion 213 and the lower surface of the tempered glass 123 is set, and the distance between the bottom of the second mounting protrusion 223 and the upper surface of the tempered glass 123 is set. The upper mold base 22 is provided with a pouring gate 24 at its front end, which is connected to the front end of the molding chamber 23 through a first flow channel 25; the upper mold base 22 and the lower mold base 21 are provided with an exhaust channel 26 at their rear ends, which is connected to the rear end of the molding chamber 23.
[0038] More specifically, by providing a first lower punch 212 at the top of the lower mold core 211 and a first upper punch 222 at the bottom of the upper mold core 221, and providing a first mounting protrusion 213 at the top of the first lower punch 212 and a second mounting protrusion 223 at the top of the first upper punch 222; after the upper mold base 22 and the lower mold base 21 are opened, the lower pressure ring 122 of the visible glass structure 12 is aligned with the first mounting protrusion 213, and the side of the first mounting protrusion 213 abuts against the second abutting inclined surface 1224; the upper mold base 22 can close with the lower mold base 21, so that the second mounting protrusion 223 abuts against the first abutting inclined surface 1214, so that the upper pressure ring 121 and the lower... The outer surface of the pressure ring 122 is located within the molding chamber 23 and can seal the position of the tempered glass 123. During die casting, after the aluminum alloy slurry enters the molding chamber 23, it can be die-cast to form the outer shell body 11 and cover the outer surfaces of the upper pressure ring 121 and the lower pressure ring 122 without entering the position of the tempered glass 123. This allows the upper pressure ring 121 and the lower pressure ring 122 to be embedded in the metal of the outer shell body 11 for fixation. With this structure, there is no need to apply glue and then press the tempered glass 123 together, nor is it necessary to use screws to fix the tempered glass 123. This not only improves the product yield but also extends the service life and improves the production efficiency of the product. Meanwhile, after the upper mold base 22 and the lower mold base 21 are closed, the installation tightness between the upper pressure ring 121 and the lower pressure ring 122 can be further adjusted, thereby further improving the sealing performance between the upper pressure ring 121 and the lower pressure ring 122 and the tempered glass 123, thus improving the production yield of the product.
[0039] It should be noted that the outer surface of the first mounting protrusion 213 has an inclined surface adapted to the second abutting inclined surface 1224, and the outer surface of the second mounting protrusion 223 has an inclined surface adapted to the second abutting inclined surface 1224. After the second mounting protrusion 223 abuts against the first abutting inclined surface 1214 and the first mounting protrusion 213 abuts against the second inclined surface 1221, the upper pressure ring 121 and the lower pressure ring 122 can be pressed together, and demolding can be performed subsequently.
[0040] The following describes in detail a die-casting method for an automotive motor housing 10 having a viewing glass structure 12, provided in this application. This die-casting method is applied to a die-casting mold 20 for the automotive motor housing 10 having the viewing glass structure 12. The die-casting method includes... Step 1: Provide a die casting machine, install the lower mold base 21 on the fixed worktable of the die casting machine, and install the upper mold base 22 on the movable worktable of the die casting machine.
