Description

Technical Field

[0001] This invention belongs to the field of automotive parts manufacturing technology, specifically relating to an injection mold for automotive parts with rapid prototyping capabilities. Background Technology

[0002] In the injection molding process of automotive parts, mold temperature directly affects product molding quality and production efficiency. Existing molds mostly rely on circulating water through cooling channels for cooling; however, the channel design is often a simple straight-hole structure, which is difficult to conform to the complex curved surfaces of the product, leading to uneven cooling, localized overheating, and prolonged cooling time. At the same time, cooling parameters are mostly set manually based on experience, lacking real-time feedback and dynamic adjustment of mold temperature changes, thus hindering the shortening of injection molding cycles and the improvement of product yield.

[0003] Patent CN222858596U discloses an easy-to-clean injection mold for automotive parts, including a base. A workbench is fixedly connected to the top of the base. Multiple evenly distributed hydraulic rods are fixedly connected to the top of the workbench. A mounting plate is fixedly connected to the top of the hydraulic rods. An injection molding machine is mounted on the top of the mounting plate. An upper mold is fixedly connected to the bottom of the mounting plate. A fixing plate is fixedly connected to the bottom of the workbench. A support column is fixedly connected to the middle of the top side of the fixing plate. A support plate is fixedly connected to the top of the support column. A lower mold abuts against the top of the support plate. When the two clamping plates move away from the lower mold, the lower mold can slide out of the workbench for cleaning. The output end of the cooling box delivers condensate to the inside of the cooling pipe. The condensate flowing inside the cooling pipe cools the lower mold, thereby accelerating plastic molding.

[0004] The above-mentioned device also has the following problems: After the mold is closed and the cavity injection is completed, when the device uses condensate to cool the lower mold, the lower mold is easily cooled while the upper mold is not cooled, which reduces the molding speed of the ring-shaped workpiece and affects the subsequent workpiece injection molding production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an injection mold for automotive parts with rapid prototyping function, so as to solve the problem of slow workpiece forming speed after injection molding.

[0006] To achieve the above objectives, the present invention provides an injection mold for automotive parts with rapid prototyping function, comprising: a machine body, a support frame mounted on the machine body, a feeding mechanism mounted on the inner wall of the support frame, a support mechanism mounted on the inner wall of the feeding mechanism, a cylinder 1 fixedly connected to the inner wall of the machine body, a mounting plate fixedly connected to the telescopic end of the cylinder 1, an injection molding machine mounted on the top of the mounting plate, an upper mold fixedly connected to the bottom of the mounting plate, a second cylinder fixedly connected to the inner wall of the machine body, a lower mold fixedly connected to the telescopic end of the second cylinder, a guide post fixedly connected to the inner wall of the machine body, and a... The device includes a water storage tank with a connecting water pipe.

A water pump is installed on the inner wall of the water storage tank. An ejector pin is installed inside the lower mold. The injection molding machine can simultaneously inject and fill the cavity. Coolant is discharged into the external cooling groove inside the lower mold for circulation. During the movement of the coolant in the external cooling groove, it can carry away heat from the lower mold, accelerating the molding speed of automotive parts and improving the injection molding efficiency of the device.

[0007] According to another advantageous design of the invention, the mounting plate contacts the guide post, and the guide post is used to provide a moving guide for the mounting plate. The connecting water pipe is connected to the lower mold, and the coolant can enter the inner cooling tank through the sealing alignment block and circulate. At this time, the coolant in the inner cooling tank can cool the inner surface of the workpiece to be plasticized during the circulation process, which can accelerate the molding efficiency and quality of the device.

[0008] According to another advantageous design of the invention, the flow divider is located on the movement trajectory of the sealing alignment block, and the sealing alignment block is used to enable the upper mold and the lower mold to communicate with each other. The lower mold is located directly below the upper mold. When the lower mold rises, the mounting plate can drive the upper mold to rise through cylinder one. After cylinder two rises a certain distance, cylinder two will drive the lower mold to reset.

The bottom cooling plate can cool and exchange heat on the bottom of the lower mold, improve the cooling effect of the mold, and thus promote the forming speed of automotive ring parts.

[0010] According to another advantageous design of the present invention, the feeding mechanism further includes a connecting frame, which is fixedly connected to the left side of the support. An electric telescopic rod is fixedly connected to the inner wall of the connecting frame, and a mounting block is fixedly connected to the telescopic end of the electric telescopic rod. A fixing arc plate is fixedly connected to the right side of the mounting block. The workpiece can be fixed and suspended by the fixing arc plate to avoid obstruction by related equipment and affect the material picking speed. This can speed up the subsequent material picking speed of the workers and indirectly improve the forming efficiency of the device.

[0011] According to another advantageous design of the present invention, the machine body is located on the movement trajectory of the connecting column, the one-way valve is connected to the machine body through an electric valve, the one-way valve is connected to the connecting pipe, the connecting pipe is fixedly connected to the bottom of the water storage tank and is connected to the water storage tank, the connecting column is connected to the bottom cooling plate, the lower mold is fixedly connected to the telescopic end of the first elastic telescopic rod, the telescopic end of the electric telescopic rod will drive the fixed arc plate to move, and after the fixed arc plate moves a certain distance, the first cylinder drives the mounting plate to rise.

[0012] According to another advantageous design of the present invention, the support mechanism includes an L-rod fixedly connected to the front of the mounting block, and a second elastic telescopic rod fixedly connected to the right side of the L-rod. A support plate is fixedly connected to the telescopic end of the second elastic telescopic rod, and the support plate can be reset by the second elastic telescopic rod. At this time, the second elastic telescopic rod can be located at the bottom of the workpiece and provide bottom support for the workpiece, which can prevent the workpiece from falling and causing damage, and improve the molding production quality of the device.

[0013] According to another advantageous design of the present invention, the support mechanism further includes a slot block, which is fixedly connected to the front of the L-rod, and a limiting post is fixedly connected to the left side of the support plate. The limiting post can connect the support plate and the L-rod relative to each other, which can ensure the stability of the support plate, improve the connection strength of the support plate, and ensure the normal discharge of the workpiece.

[0014] According to another advantageous design of the present invention, the limiting post contacts the slot block, and the limiting post is used to enhance the connection strength of the support plate. The movement of the support plate will synchronously drive the limiting post to move. At the same time, when the support plate approaches the L rod, the support plate will synchronously drive the limiting post to move.

This injection mold for automotive parts with rapid prototyping function utilizes the coordinated movement of an elastic telescopic rod, a bottom cooling plate, a connecting column, a one-way valve, a connecting pipe, a connecting frame, an electric telescopic rod, a mounting block, and a fixed arc plate. This allows the bottom cooling plate to cool and exchange heat at the bottom of the lower mold, improving the mold's cooling effect and thus accelerating the molding speed of automotive ring parts. The workpiece can be fixed and suspended by the fixed arc plate, preventing obstruction by related equipment and ensuring a faster material handling speed. This, in turn, speeds up the subsequent material handling by workers and indirectly improves the molding efficiency of the device.

[0017] 3.

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figures 1-10 As shown, one embodiment of the present invention is an injection mold for automotive parts with rapid prototyping function, comprising: a body 1, a support 2 mounted on the body 1, a feeding mechanism 3 mounted on the inner wall of the support 2, a support mechanism 4 mounted on the inner wall of the feeding mechanism 3, a cylinder 5 fixedly connected to the inner wall of the body 1, a mounting plate 6 fixedly connected to the telescopic end of the cylinder 5, an injection molding machine 7 mounted on the top of the mounting plate 6, an upper mold 8 fixedly connected to the bottom of the mounting plate 6, and a... Cylinder 2 9, the telescopic end of cylinder 2 9 is fixedly connected to the lower mold 10, the inner wall of the machine body 1 is fixedly connected to the guide column 11, the right side of the machine body 1 is provided with a water storage tank 12, the water storage tank 12 is provided with a connecting water pipe, the inner wall of the lower mold 10 is provided with an external cooling groove 13, the inner wall of the upper mold 8 is provided with an internal cooling groove 14, the inner wall of the upper mold 8 is fixedly connected with a sealing alignment block 15, the lower mold 10 is provided with a flow divider groove, the inner wall of the water storage tank 12 is provided with a water pump, and the lower mold 10 is provided with an ejector pin. When the device is in use, cylinder 5 will start, and the telescopic end of cylinder 5 will drive the mounting plate 6 to move downward. The movement of the mounting plate 6 will drive the injection molding machine 7 to move. At the same time, the movement of the mounting plate 6 will also drive the upper mold 8 to move. After the upper mold 8 moves a certain distance, it will contact the lower mold 10 and complete the mold closing operation, forming a cavity. Then, the injection molding machine 7 can simultaneously inject and fill the cavity. After the mold filling is completed, the water pump in the water tank 12 will start and discharge the coolant into the external cooling tank 13 opened in the lower mold 10 through the connecting water pipe for circulation. During the movement of the coolant in the external cooling tank 13, it can carry away the heat on the lower mold 10, which can accelerate the molding speed of automotive parts and improve the injection molding efficiency of the device. Mounting plate 6 contacts guide post 11, and guide post 11 is used to provide movement guidance for mounting plate 6. Connecting water pipe is connected to lower mold 10. Diversion groove is located on the movement trajectory of sealing alignment block 15, and sealing alignment block 15 is used to connect upper mold 8 and lower mold 10. Lower mold 10 is located directly below upper mold 8. When the device is in use and is ready to open the mold and remove material, cylinder 29 can drive the lower mold 10 to rise before opening the mold. Simultaneously, the mounting plate 6 can drive the upper mold 8 to rise via cylinder 15. After rising a certain distance, cylinder 29 will then drive the lower mold 10 to reset. Similarly, the mounting plate 6 will also drive the upper mold 8 to reset via cylinder 15. Before opening the mold, cylinder 15 drives the upper mold 8 to move upwards, while cylinder 29 keeps the lower mold 10 in the same position, completing the separation of the parting surface. Then, cylinder 29 drives the lower mold 10 to... As the mold rises, it is easier to remove the part. At the same time, as the upper mold 8 moves downward, the upper mold 8 will simultaneously drive the sealing alignment block 15 to move. After the upper mold 8 and the lower mold 10 are closed, the sealing alignment block 15 can be connected to the outer cooling tank 13. After the coolant is discharged into the outer cooling tank 13, the coolant can enter the inner cooling tank 14 through the sealing alignment block 15 and circulate. At this time, the coolant in the inner cooling tank 14 can cool the inner surface of the workpiece to be plasticized during the circulation, which can speed up the molding efficiency and quality of the device. Overall working principle: The injection molding machine 7 can simultaneously inject and fill the cavity. The coolant is discharged into the outer cooling tank 13 opened in the lower mold 10 for circulation. During the movement of the coolant in the outer cooling tank 13, it can carry away the heat on the lower mold 10, which can accelerate the molding speed of automotive parts and improve the injection molding efficiency of the device. The coolant can enter the inner cooling tank 14 through the sealing alignment block 15 and circulate. At this time, the coolant in the inner cooling tank 14 can cool the inner surface of the workpiece to be plasticized during the circulation, which can accelerate the molding efficiency and quality of the device.

[0022] like Figures 1-10 As shown, based on the above embodiment, the feeding mechanism 3 includes an elastic telescopic rod 301, which is fixedly connected to the inner wall of the machine body 1. The bottom of the lower mold 10 is fixedly connected to a bottom cooling plate 302, and the inner wall of the bottom cooling plate 302 is fixedly connected to a connecting column 303. The inner wall of the machine body 1 is fixedly connected to a one-way valve 304, and the bottom of the one-way valve 304 is fixedly connected to a connecting pipe 305. The bottom of the bottom cooling plate 302 is provided with an annular sealing groove, and a high-temperature resistant sealing ring is embedded in the groove. When the bottom cooling plate 302 moves down to contact the one-way valve 304, the sealing ring is pressed and sealed with the interface end face of the one-way valve 304 to form a coolant passage. When the device is in use, after the lower mold 10 closes with the upper mold 8, the lower mold 10 moves downward. During this downward movement, the lower mold 10 compresses the elastic telescopic rod 301. The elastic telescopic rod 301 provides cushioning for the lower mold 10, preventing damage. Simultaneously, the lower mold 10 moves the bottom cooling plate 302 downward. After moving a certain distance, the bottom cooling plate 302 contacts the one-way valve 304. When 02 moves down to contact the one-way valve 304, the sealing ring is pressed and sealed with the interface end face of the one-way valve 304 to form a coolant passage. At this time, the electric valve of the one-way valve 304 can open synchronously, which allows the connecting pipe 305 to connect with the connecting column 303. The coolant in the water tank 12 can move sequentially to the bottom cooling plate 302 through the connecting pipe 305. At this time, the bottom cooling plate 302 can cool and exchange heat on the bottom of the lower mold 10, improve the cooling effect of the mold, and thus promote the molding speed of the automotive ring parts. The unloading mechanism 3 also includes a connecting frame 306, which is fixedly connected to the left side of the bracket 2. An electric telescopic rod 307 is fixedly connected to the inner wall of the connecting frame 306. An installation block 308 is fixedly connected to the telescopic end of the electric telescopic rod 307. A fixed arc plate 309 is fixedly connected to the right side of the installation block 308. The machine body 1 is located on the movement trajectory of the connecting column 303. A one-way valve 304 is connected to the machine body 1 through an electric valve. The one-way valve 304 is connected to the connecting pipe 305. The connecting pipe 305 is fixedly connected to the bottom of the water storage tank 12 and is connected to the water storage tank 12. The connecting column 303 is connected to the bottom cooling plate 302. The lower mold 10 is fixedly connected to the telescopic end of the elastic telescopic rod 301. An elastic anti-slip pad is provided on the inner arc surface of the fixed arc plate 309. A compression spring is provided between the installation block 308 and the connecting frame 306 so that the fixed arc plate 309 applies a constant radial clamping force to the workpiece to prevent the workpiece from slipping. When the device is preparing to open the mold, cylinder 29 will drive the lower mold 10 to rise to the same horizontal plane as the fixed arc plate 309. At this time, the electric telescopic rod 307 will be activated, and the telescopic end of the electric telescopic rod 307 will drive the fixed arc plate 309 to move. After the fixed arc plate 309 moves a certain distance, cylinder 15 will drive the mounting plate 6 to rise. The movement of the mounting plate 6 will drive the upper mold 8 to rise, thus opening the mold. At this time, the ejector pins in the lower mold 10 can eject part of the workpiece. After moving a certain distance, the fixed arc plate 309 can contact the surface of the workpiece and fix the workpiece. At this time, the lower mold 10 will return to the initial position, and the workpiece can be fixed and suspended by the fixed arc plate 309, avoiding obstruction by related equipment and affecting the material handling speed. This can speed up the subsequent material handling speed of the workers and indirectly improve the molding efficiency of the device. The support mechanism 4 includes an L-rod 401, which is fixedly connected to the front of the mounting block 308. An elastic telescopic rod 402 is fixedly connected to the right side of the L-rod 401, and a support plate 403 is fixedly connected to the telescopic end of the elastic telescopic rod 402. When the device is in use, during the movement of the mounting block 308, the mounting block 308 will synchronously drive the L rod 401 to move. The movement of the L rod 401 will drive the elastic telescopic rod 402 to move. The movement of the elastic telescopic rod 402 will drive the support plate 403 to move. After the support plate 403 moves a certain distance, it will contact the lower mold 10 after it has risen. At this time, the lower mold 10 can press the support plate 403 in the opposite direction as the support plate 403 continues to move. The support plate 403 can compress the elastic telescopic rod 402 and shorten the distance between itself and the support plate 403 until the fixed arc plate 309 contacts the workpiece to complete the fixation of the workpiece. Then the lower mold 10 will move and reset. At this time, after the lower mold 10 resets, the support plate 403 can be reset through the elastic telescopic rod 402. At this time, the elastic telescopic rod 402 can be located at the bottom of the workpiece and provide bottom support for the workpiece, which can prevent the workpiece from falling and causing damage, and improve the molding production quality of the device. The support mechanism 4 also includes a slot block 404, which is fixedly connected to the front of the L rod 401. A limit post 405 is fixedly connected to the left side of the support plate 403. The limit post 405 contacts the slot block 404 and is used to enhance the connection strength of the support plate 403. During use, the movement of the support plate 403 will synchronously drive the movement of the limiting post 405. At the same time, when the support plate 403 approaches the L rod 401, the support plate 403 will synchronously drive the limiting post 405 to move. During the movement, the limiting post 405 will slide on the inner wall of the slot block 404. The limiting post 405 can connect the support plate 403 and the L rod 401, which can ensure the stability of the support plate 403, improve the connection strength of the support plate 403, and ensure the normal output of the workpiece. Overall working principle: The bottom cooling plate 302 can cool and exchange heat at the bottom of the lower mold 10, improving the cooling effect of the mold and thus promoting the forming speed of automotive ring parts. The workpiece can be fixed and suspended by the fixed arc plate 309 to avoid obstruction by related equipment and affect the material handling speed, thereby speeding up the subsequent material handling speed of the workers and indirectly improving the forming efficiency of the device. The support plate 403 can be reset by the elastic telescopic rod 402. At this time, the elastic telescopic rod 402 can be located at the bottom of the workpiece and provide bottom support for the workpiece, which can prevent the workpiece from falling and causing damage, and improve the forming production quality of the device. The limiting post 405 can connect the support plate 403 and the L rod 401 to ensure the stability of the support plate 403, improve the connection strength of the support plate 403, and ensure the normal output of the workpiece.
