Description

Technical Field

[0001] This invention relates to the field of injection mold technology, specifically to an injection mold for the outer casing of a solar lamp. Background Technology

[0002] This solar lamp housing injection molding mold belongs to the field of injection molding technology and is deeply integrated into the intelligent manufacturing equipment industry. This mold is suitable for intelligent injection molding of integrated or separate plastic housings of solar lamp housings, lamp holders, and lamp shades. It is an important part of the precision molding equipment field in the intelligent manufacturing equipment industry, connecting the coordinated development of the outdoor lighting industry and the intelligent manufacturing equipment industry, and helping the industry to transform towards digitalization, intelligence, and greening.

[0003] Chinese patent CN223948382U discloses a structure that can automatically inject and discharge coolant along with the mold, which can improve the cooling efficiency in the injection molding process and reduce the wear of the sliding block by setting an arc-shaped groove structure. However, in this patent solution, the lubrication of the mold positioning pins mainly relies on the pre-placed lubricant, and there is no automatic lubricant replenishment mechanism. As the mold runs back and forth for a long time, the lubricant will be gradually consumed and cannot maintain a stable lubrication state. This can easily lead to increased gaps and shaking of the positioning pins, which in turn affects the docking accuracy of the coolant injection and discharge channels and reduces the stability and reliability of the mold operation.

[0004] To address the aforementioned issues, we propose an injection molding mold for the outer casing of a solar lamp. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an injection molding mold for the outer casing of a solar lamp. The mold's reciprocating motion allows for the quantitative and continuous replenishment of lubricating fluid to the positioning posts, while also replenishing the lubricating fluid to the main reservoir. This maintains a stable lubrication state over the long term, effectively preventing problems such as shaking and wear of the positioning posts due to insufficient lubrication. This significantly improves the stability, fitting accuracy, and service life of the mold.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a solar lamp housing injection molding mold, comprising an upper module and a lower module, wherein the upper module has symmetrically arranged storage cavities at the front and back of its upper part, and a replenishment connection valve is fixedly installed on the upper side of the inner wall of each of the two storage cavities; positioning posts are fixedly installed at the four corners of the bottom of the upper module; an oil connection pipe is fixedly installed on one side of each of the two positioning posts inside the storage cavity; the lower end of the oil connection pipe penetrates the interior of the upper module and is fixedly connected to the surface of the positioning post, thereby realizing the communication between the storage cavity and the positioning post, for conveying lubricating fluid to the positioning post; a conveying component is provided on the inner wall of each of the two storage cavities; and a switch component is provided at the bottom of each of the two replenishment connection valves.

[0008] The switch assembly includes an outer sleeve fixedly installed at the bottom of the supply connection valve. An inner sleeve is slidably installed on the inner wall of the outer sleeve. Several through holes are opened at the lower part of the outer sleeve and the upper part of the inner sleeve. A fixed plate is fixedly installed at the bottom of the inner sleeve. Two limiting hole blocks are integrally formed on the left and right sides of the fixed plate. Limiting vertical rods are slidably installed on the inner walls of the two limiting hole blocks. A power assembly is provided at the bottom of the fixed plate.

[0009] Furthermore, mounting columns are fixedly installed at the four corners of the opposite sides of the upper and lower modules, and two lifting rings for lifting are fixedly installed on the left side of both the upper and lower modules.

[0010] Furthermore, a pressure relief valve is fixedly installed on the upper side of the inner wall of each of the two storage cavities, on the side of the supply connection valve.

[0011] Furthermore, all four positioning columns are hollow cylindrical structures, and each positioning column has several liquid outlet blind holes on its outer peripheral surface. These liquid outlet blind holes are used to achieve quantitative output of lubricating fluid, so that the surface of the positioning column is uniformly lubricated, reducing the wear of the positioning column and improving operational stability.

[0012] Furthermore, the check valve only allows lubricant to flow unidirectionally from top to bottom, preventing the lubricant below the perforated plate from flowing back upwards. The lower ends of the two corresponding arc-head rods extend through to the bottom of the upper module, and tension springs are sleeved on the rod walls located on the lower side of the perforated plate. The upper ends of the tension springs are fixedly connected to the bottom of the perforated plate, and the lower ends of the tension springs are fixedly connected to the lower side of the inner wall of the storage cavity.

[0013] Furthermore, triangular prisms for support and limiting are fixedly installed on both the left and right sides of the inner wall of the storage cavity.

[0014] Furthermore, the through holes can connect and overlap each other when the inner sleeve moves downward, so that the lubricating fluid in the pipeline connected to the replenishment valve can enter smoothly. The upper ends of the two corresponding limiting vertical rods are fixedly connected to the upper side of the inner wall of the storage cavity, and both limiting vertical rods are rods with an enlarged head structure at one end.

[0015] Furthermore, the power assembly includes a movable slot plate fixedly installed at the bottom of the fixed disk, a connecting slot plate slidably installed on the inner wall of the movable slot plate, and a plurality of limiting cylinders fixedly installed in the middle of the surface of the connecting slot plate. The surfaces of the plurality of corresponding limiting cylinders are engaged with concave wheels, and the surface of the concave wheels is provided with a drive crank rod.

[0016] Furthermore, the inner wall of the movable groove plate is a trapezoidal inner wall, and the surface of the connecting groove plate is adapted to the inner wall of the movable groove plate, and the two form a trapezoidal guiding fit. An arc-shaped guide groove is provided on one side surface of the connecting groove plate to realize motion guidance and sliding fit.

[0017] Furthermore, the concave wheel is a disc-shaped component with several internal grooves on its end face. The internal grooves can engage with the corresponding limiting cylinders, thereby driving the connecting groove plate connected to the limiting cylinders to slide along the inner wall of the moving groove plate.

[0018] The concave wheel and the drive crank are connected by a one-way bearing, ensuring the one-way rotation of the drive crank. The drive crank is a rod structure with a crank pin. The side of the drive crank away from the connecting slot plate is rotatably connected to the side of the inner wall of the storage cavity. Reinforcing plates are rotatably installed on both sides of the drive crank located opposite the crank pin, and the top of the reinforcing plates is fixedly connected to the upper side of the inner wall of the storage cavity. The crank pin of the drive crank is rotatably installed with a connecting shaft, and the bottom of the connecting shaft is rotatably connected to the bottom of the perforated plate. One end of the drive crank extends to the inner wall of the connecting slot plate and is slidably connected to its inner wall.

[0020] 1. This device can use the reciprocating motion of the mold itself to quantitatively and continuously replenish the lubricating fluid to the positioning pins, and at the same time replenish the lubricating fluid to the main reservoir, maintaining a stable lubrication state for a long time.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 9The solar lamp housing injection molding mold in this embodiment includes an upper module 1 and a lower module 2. The upper module 1 and the lower module 2 are correspondingly arranged. After the mold is closed, an injection cavity for the solar lamp housing is formed for molding molten plastic.

[0038] Mounting columns 101 are fixedly installed at the four corners of the opposite sides of the upper module 1 and the lower module 2. The mounting columns 101 are used as auxiliary positioning structures on other devices during the installation process of the upper module 1 and the lower module 2. Two lifting rings 102 for lifting are fixedly installed on the left side of the upper module 1 and the lower module 2. The lifting rings 102 are made of high-strength alloy material and are used for lifting and transporting the mold, which facilitates the installation and maintenance of the mold.

[0039] Two storage cavities 3 are symmetrically opened at the front and back of the upper module 1. Both storage cavities 3 are sealed cavities used to store lubricating fluid to provide continuous lubrication for the positioning column 5. Triangular prisms 301 for support and limiting are fixedly installed on the left and right sides of the inner wall of the two storage cavities 3. The triangular prisms 301 are used to limit the sliding of the perforated plate 701 to ensure the stable operation of the conveying component 7.

[0040] A replenishment connection valve 4 is fixedly installed on the upper side of the inner wall of each of the two storage chambers 3. The replenishment connection valve 4 is used to connect to the external lubricant replenishment pipeline to realize the overall replenishment of lubricant in the storage chamber 3. A pressure relief valve 401 is fixedly installed on the upper side of the inner wall of each of the two storage chambers 3, located on the side of the replenishment connection valve 4. The pressure relief valve 401 is used to balance the air pressure inside the storage chamber 3. When the air pressure inside the storage chamber 3 is too high, the pressure relief valve 401 automatically opens to relieve pressure, so as to avoid damage to the storage chamber 3 due to excessive air pressure, and at the same time ensure the stability of lubricant delivery.

[0041] Positioning posts 5 are fixedly installed at the four corners of the bottom of the upper module 1. The positioning posts 5 are used for precise positioning when the upper module 1 and the lower module 2 are closed, ensuring the sealing of the injection cavity and avoiding problems such as burrs and glue leakage during injection. The four positioning posts 5 are all hollow cylindrical structures, and several liquid outlet blind holes 501 are opened on the outer peripheral surface of each positioning post 5. The liquid outlet blind holes 501 are used to realize the quantitative output of lubricating fluid, so that the surface of the positioning post 5 is uniformly lubricated, reducing the wear of the positioning post 5, improving the operational stability, and preventing the positioning post 5 from shaking due to insufficient lubrication, thereby ensuring the precise matching of coolant injection and discharge.

[0042] Inside the storage cavity 3, oil connection pipes 6 are fixedly installed on one side of each of the two corresponding positioning posts 5. The lower end of the oil connection pipe 6 penetrates the interior of the upper module 1 and is fixedly connected to the surface of the positioning post 5 to realize the communication between the storage cavity 3 and the positioning post 5. It is used to deliver lubricating fluid to the positioning post 5. The oil connection pipe 6 is made of corrosion-resistant and high-temperature resistant engineering plastic to avoid aging and leakage due to long-term contact with lubricating fluid.

[0043] The inner walls of both storage chambers 3 are equipped with conveying components 7, which are used to quantitatively convey the lubricating fluid in the storage chamber 3 to the positioning column 5. The bottom of both replenishment connection valves 4 is equipped with a switch component 8, which is used to control the connection and closing between the replenishment connection valve 4 and the storage chamber 3, so as to realize the replenishment of lubricating fluid on demand.

[0044] The conveying assembly 7 includes a perforated plate 701 slidably connected to the inner wall of the storage cavity 3. The perforated plate 701 is slidably sealed to the inner wall of the storage cavity 3 and is used to push the lubricating fluid in the storage cavity 3 downward. Each through hole 803 on the bottom surface of the perforated plate 701 is provided with a check valve 702. The check valve 702 only allows the lubricating fluid to flow in one direction from top to bottom, and prevents the lubricating fluid below the perforated plate 701 from flowing back upward, ensuring the one-way delivery of the lubricating fluid and avoiding the failure of the supply due to the backflow of the lubricating fluid.

[0045] Two arc-shaped rods 703 are fixedly installed at the bottom of the perforated plate 701. The lower ends of the two corresponding arc-shaped rods 703 extend through to the bottom of the upper module 1. The lower ends of the arc-shaped rods 703 are arc-shaped to avoid jamming or wear when in contact with the lower module 2. Each arc-shaped rod 703 is fitted with a tension spring 7031 on the lower side of the perforated plate 701. The upper end of the tension spring 7031 is fixedly connected to the bottom of the perforated plate 701, and the lower end of the tension spring 7031 is fixedly connected to the lower side of the inner wall of the storage cavity 3. The tension spring 7031 is used to reset the perforated plate 701. When the upward force on the perforated plate 701 disappears, the tension spring 7031 can drive the perforated plate 701 to reset downward, preparing for the next lubricant delivery.

[0046] The switch assembly 8 includes an outer sleeve 801 fixedly installed at the bottom of the supply connection valve 4. The outer sleeve 801 is connected to the supply connection valve 4 and is used to transmit lubricating fluid. An inner sleeve 802 is slidably installed on the inner wall of the outer sleeve 801. The inner sleeve 802 is slidably sealed with the inner wall of the outer sleeve 801 and can slide up and down along the inner wall of the outer sleeve 801. Several through holes 803 are provided at the lower part of the outer sleeve 801 and the upper part of the inner sleeve 802. The through holes 803 can be interconnected and overlapped when the inner sleeve 802 moves downward, so that the lubricating fluid in the pipeline connected to the supply connection valve 4 can smoothly enter the storage chamber 3. When the inner sleeve 802 moves upward, the through holes 803 are staggered, so as to close the supply connection valve 4 and the storage chamber 3 and stop the supply of lubricating fluid.

[0047] A fixed plate 804 is fixedly installed at the bottom of the inner sleeve 802. The fixed plate 804 is used to connect the inner sleeve 802 and the power component 9, and drive the inner sleeve 802 to slide up and down. Two limiting holes 805 are integrally formed on the left and right sides of the fixed plate 804. Limiting vertical rods 806 are slidably installed on the inner walls of the two limiting holes 805. The upper ends of the two corresponding limiting vertical rods 806 are fixedly connected to the upper side of the inner wall of the storage cavity 3. The limiting vertical rods 806 are used to guide and limit the sliding of the fixed plate 804, prevent the fixed plate 804 from deviating when sliding, and ensure the stable operation of the switch component 8. Both limiting vertical rods 806 are rods with an enlarged head structure at one end. The enlarged head structure can prevent the fixed plate 804 from falling off the limiting vertical rods 806 and improve the reliability of the structure.

[0048] The power assembly 9 includes a movable slot plate 906 fixedly installed at the bottom of the fixed disk 804. The inner wall of the movable slot plate 906 is trapezoidal. A connecting slot plate 901 is slidably installed on the inner wall of the movable slot plate 906. The surface of the connecting slot plate 901 is adapted to the inner wall of the movable slot plate 906, and the two form a trapezoidal guide fit. The trapezoidal guide fit can improve the sliding stability of the connecting slot plate 901 and prevent the connecting slot plate 901 from deviating when sliding. An arc-shaped guide groove is opened on one side surface of the connecting slot plate 901 to realize motion guidance and sliding fit, further improving the smoothness of the sliding of the connecting slot plate 901.

[0049] A number of limiting cylinders 902 are fixedly installed in the middle of the surface of the connecting groove plate 901. The surfaces of the corresponding limiting cylinders 902 are connected to the concave wheel 903. The concave wheel 903 is a disc-shaped component with a number of inner grooves on its end face. The inner grooves can engage with the corresponding limiting cylinders 902, thereby driving the connecting groove plate 901 connected to the limiting cylinders 902 to slide along the inner wall of the moving groove plate 906. The surface of the concave wheel 903 is provided with a driving crank rod 904. The concave wheel 903 and the driving crank rod 904 are connected by a one-way bearing 9031. The one-way bearing 9031 can ensure the one-way rotation driving effect of the driving crank rod 904, that is, the driving crank rod 904 can only drive the concave wheel 903 to rotate in one direction. When rotating in the opposite direction, it does not drive the concave wheel 903.

[0050] The drive crank 904 is a rod structure with a crank pin. The side of the drive crank 904 away from the connecting slot plate 901 is rotatably connected to the side of the inner wall of the storage cavity 3, realizing the rotatable installation of the drive crank 904. Reinforcing plates 9041 are rotatably installed on both sides of the drive crank 904 opposite to the crank pin, and the top of the reinforcing plates 9041 is fixedly connected to the upper side of the inner wall of the storage cavity 3. The reinforcing plates 9041 are used to reinforce and support the drive crank 904, improving the stability of the rotation of the drive crank 904. The crank pin of the drive crank 904 is rotatably installed with a connecting shaft 905, and the bottom of the connecting shaft 905 is rotatably connected to the bottom of the perforated plate 701, realizing the linkage between the drive crank 904 and the perforated plate 701, driving the perforated plate 701 to slide up and down.

[0051] The working principle of the above embodiments is as follows:

[0052] During the use of the device, the upper module 1 moves downward, and the arc-shaped rod 703 at the bottom of the upper module 1 contacts the lower module 2. The lower module 2 generates an upward thrust on the arc-shaped rod 703, pushing the arc-shaped rod 703 upward. The arc-shaped rod 703 drives the perforated plate 701 to slide upward along the inner wall of the storage cavity 3. At this time, the tension spring 7031 below the perforated plate 701 is stretched. When the perforated plate 701 slides upward, the volume of the space below it increases and the air pressure decreases. Since the check valve 702 only allows the lubricating fluid to flow unidirectionally from top to bottom, the check valve 702 is in the open state at this time, and the lubricating fluid in the storage cavity 3 will flow downward.

[0053] When the mold opens, the upper module 1 moves upward, the arc head rod 703 separates from the lower module 2, and the pushing force of the lower module 2 on the arc head rod 703 disappears. At this time, the tension spring 7031 releases its elastic potential energy, pulling the perforated plate 701 to slide downward along the inner wall of the storage cavity 3. When the perforated plate 701 slides downward, it generates downward pressure on the lubricant below it. At this time, the check valve 702 is closed, so the lubricant will flow out through the liquid outlet blind hole 501 under the tension of the tension spring 7031. During the process of the upper module 1 and the lower module 2 merging, although the check valve 702 is open, the liquid can only be forced into the lower side of the perforated plate 701 under pressure. This is beneficial for the tension spring 7031 to push out the lubricant when the upper module 1 and the lower module 2 open, thereby achieving lubrication of the positioning column 5, reducing the wear of the positioning column 5, and ensuring the operational stability of the positioning column 5.

[0054] During the injection molding process, the mold will continuously move up and down towards the compound mold and open the mold. The above process is repeated continuously to achieve continuous and quantitative lubricant supply to the positioning post 5, always ensuring that there is a certain amount of lubricant on the surface of the positioning post 5, avoiding the positioning post 5 from shaking due to insufficient lubrication, thereby ensuring the mold closing accuracy, ensuring the quality of the injection molding of the solar lamp shell, and at the same time avoiding the problem of misalignment or mismatch between coolant injection and discharge.

[0055] The lubricant in the storage cavity 3 is replenished after the reciprocating motion of the upper module 1 and the lower module 2 has been completed for a certain period of time. During the up-and-down movement of the perforated plate 701, the connecting shaft 905 can pull the drive crank 904 to rotate. Since the drive crank 904 and the inner concave wheel 903 are connected by a one-way bearing 9031, the rotation of the drive crank 904 drives the inner concave wheel 903 to rotate synchronously in one direction.

[0056] When the concave wheel 903 rotates, the inner groove on its end face engages with the limiting cylinder 902 on the connecting groove plate 901, causing the connecting groove plate 901 to slide along the trapezoidal inner wall of the movable groove plate 906. When the connecting groove plate 901 slides, when it slides at the bent position, the vertical position of the arc groove changes, which can drive the movable groove plate 906 to move up and down. The movement of the movable groove plate 906 can drive the fixed plate 804 to move up and down. When the fixed plate 804 moves downward, it can drive the inner sleeve 802 along the inner side of the outer sleeve 801. The wall slides downwards. When the inner sleeve 802 moves downwards to the preset position, the outer sleeve 801 and the through hole 803 on the inner sleeve 802 are connected and overlapped. The replenishment connection valve 4 is connected to the storage cavity 3. The external lubricant enters the outer sleeve 801 through the replenishment connection valve 4, and then enters the storage cavity 3 through the overlapping through hole 803, realizing the overall replenishment of the lubricant in the storage cavity 3. At this time, the pressure relief valve 401 in the storage cavity 3 works synchronously to balance the air pressure inside the storage cavity 3, ensuring that the lubricant is injected smoothly and avoiding excessive air pressure from hindering the replenishment of lubricant.

[0057] When the fixed plate 804 moves upward in the arc-shaped position inside the connecting groove plate 901, the fixed plate 804 moves upward, causing the inner sleeve 802 to slide upward, so that the through hole 803 on the outer sleeve 801 and the inner sleeve 802 are misaligned, the replenishment connection valve 4 and the storage chamber 3 are closed, the lubricant replenishment is stopped, and the overall replenishment cycle of lubricant in the storage chamber 3 is completed.

[0058] This device, through the coordinated operation of the conveying component 7, the switching component 8, and the power component 9, relies on the up-and-down compound mold movement of the mold itself to achieve quantitative and continuous lubricant replenishment of the positioning column 5. At the same time, it can automatically complete the overall replenishment of lubricant in the storage cavity 3, completely solving the problems of the existing mold positioning column 5's inability to automatically replenish lubricant and unstable lubrication effect. Through the hollow structure of the positioning column 5 and the setting of the liquid outlet blind hole 501, the quantitative output of lubricant is guaranteed, so that the surface of the positioning column 5 forms uniform lubrication, effectively reducing the wear of the positioning column 5 and avoiding the decrease in mold closing accuracy caused by the shaking of the positioning column 5.

[0059] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.

The check valve (702) only allows lubricant to flow in one direction from top to bottom, preventing the lubricant below the perforated plate (701) from flowing back upward. The lower ends of the two corresponding arc-head rods (703) extend through to the bottom of the upper module (1), and the rod wall of the arc-head rod (703) is fitted with a tension spring (7031) on the lower side of the perforated plate (701). The upper end of the tension spring (7031) is fixedly connected to the bottom of the perforated plate (701), and the lower end of the tension spring (7031) is fixedly connected to the lower side of the inner wall of the storage cavity (3). When the upper module (1) moves downward, the arc-shaped rod (703) at the bottom of the upper module (1) contacts the lower module (2), and the lower module (2) pushes the arc-shaped rod (703) to move upward. The tension spring (7031) under the perforated plate (701) is stretched. When the upper module (1) moves upward, the arc-shaped rod (703) separates from the lower module (2). At this time, the tension spring (7031) releases elastic potential energy and pulls the perforated plate (701) to slide downward along the inner wall of the storage cavity (3).

7. The injection molding mold for the solar lamp housing according to claim 6, characterized in that: The inner wall of the movable slot plate (906) is a trapezoidal inner wall, and the surface of the connecting slot plate (901) is adapted to the inner wall of the movable slot plate (906), and the two form a trapezoidal guide fit. An arc-shaped guide groove is opened on one side surface of the connecting slot plate (901).

8. The injection molding mold for the solar lamp housing according to claim 7, characterized in that: The concave wheel (903) is a disc-shaped component with several inner grooves on its end face. The inner grooves can engage with the corresponding limiting cylinder (902), thereby driving the connecting groove plate (901) connected to the limiting cylinder (902) to slide along the inner wall of the moving groove plate (906). The concave wheel (903) and the drive crank (904) are connected by a one-way bearing (9031), which can ensure the one-way rotation driving effect of the drive crank (904). The drive crank (904) is a rod structure with a crank pin. The side of the drive crank (904) away from the connecting groove plate (901) is rotatably connected to the side of the inner wall of the storage cavity (3). The drive crank (904) is rotatably mounted with a reinforcing hole plate (9041) on both sides opposite to the crank pin. The top of the reinforcing hole plate (9041) is fixedly connected to the upper side of the inner wall of the storage cavity (3). The crank pin of the drive crank (904) is rotatably mounted with a connecting shaft (905). The bottom of the connecting shaft (905) is rotatably connected to the bottom of the perforated plate (701). One end of the drive crank (904) extends to the inner wall of the connecting groove plate (901) and is slidably connected to its inner wall.
