Description

Technical Field

[0001] This invention relates to the field of compression molding equipment technology, and in particular to a composite material compression molding production device. Background Technology

[0002] In composite material production, compression molding is a process in which a certain amount of premixed or prepreg material is added into a metal mold and then cured by heating and pressure.

[0036] Example 1:

[0037] This invention provides a composite material compression molding production apparatus, such as... Figure 1-3 As shown, it includes: an upper frame 1 and a lower frame 2. The upper frame 1 is fixedly mounted on the top of the lower frame 2. An upper mold 4 is mounted on the bottom of the upper frame 1. A lower mold 5 is mounted below the upper mold 4. The lower mold 5 is fixedly connected to the top of the lower frame 2. A fixed frame 10 is mounted above the lower mold 5. A motion mechanism 3 is mounted on the fixed frame 10. A motion frame 15 is mounted at the output end of the motion mechanism 3. A high-pressure injection mixing nozzle 20 is mounted on the top of the upper mold 4. The output end of the high-pressure injection mixing nozzle 20 is connected to the input end of the upper mold 4. A drive motor 6 is mounted above the fixed frame 10. The input end of the motion mechanism 3 is electrically connected to the drive motor 6. The drive motor 6 is electrically connected to an external controller.

[0038] The working principle and beneficial effects of the above technical solution are as follows:

[0039] like Figure 1 The diagram shows the structure of the device when the mold is closed.

[0040] During production, the motion mechanism 3 connected to the drive motor 6 serves as the power source for opening and closing the mold. The output end of the motion mechanism 3 drives the upper mold 4 to move up and down along the fixed frame 10 via the motion frame 15. When the mold is ready for high-pressure injection, the motion mechanism 3 first moves the upper mold 4 upward, and the high-pressure injection mixing gun head 20 injects the composite material. After the injection is completed, the motion mechanism 3 moves the upper mold 4 downward so that the upper mold 4 and the lower mold 5 are closed, the mold is closed, and the device completes the subsequent production process.

[0041] In this device, the high-pressure injection mixing nozzle 20 adopts a professionally developed high-pressure micro-flow injection host, ensuring thorough mixing of raw materials and accurate control of injection volume, thereby improving injection efficiency. The motion mechanism 3, connected to the drive motor 6, serves as the power source for mold opening and closing. It is compact, easy to operate, and precisely controls the timing and distance of opening and closing between the upper mold 4 and the lower mold 5, improving the fullness of injection inside the mold, ensuring the quality and consistency of molded products, and helping to improve the uniformity and structural performance of molded products. It also improves the precision and quality of molded products, solving the problems of large size, high cost, inconvenient operation, difficulty in accurately controlling the mold opening timing and distance, and easy occurrence of incomplete injection in existing hydraulic and pneumatic devices for molding processes, resulting in poor material uniformity and poor structural performance of molded products.

[0042] Example 2

[0043] Based on the above embodiment 1, as follows Figure 1-3As shown, the fixing frame 10 includes: a fixing plate 11, the motion mechanism 3 is fixedly mounted on the upper end of the fixing plate 11, connecting guide rods 12 are arranged in a rectangular pattern around the fixing plate 11, the upper end of the connecting guide rods 12 passes through the fixing plate 11 and is threadedly connected to the fixing plate 11, a copper sleeve 13 is sleeved around the lower end of the connecting guide rods 12, the inner wall of the copper sleeve 13 is fixedly connected to the outer wall of the connecting guide rods 12, the lower ends of the connecting guide rods 12 and the copper sleeve 13 respectively pass through the upper mold 4 and are fixedly connected to the lower mold 5, and the copper sleeve 13 is slidably connected to the upper mold 4;

[0044] The motion frame 15 includes: a connecting plate 16, which is disposed below the fixing plate 11. The connecting plate 16 has a central hole in its center. Connecting rods 17 are arranged in a rectangular pattern around the connecting plate 16. The top of the connecting rods 17 passes through the connecting plate 16 and is threadedly connected to the connecting plate 16. The bottom of the connecting rods 17 is fixedly connected to the top of the upper mold 4.

[0045] The motion mechanism 3 includes: a housing 31, the bottom of which is fixedly connected to the top of the fixing plate 11; one side of the output end of the drive motor 6 is fixedly disposed on the top of the housing 31; a screw 32 is disposed inside the housing 31; the top of the screw 32 passes through the housing 31 and is fixedly connected to the output end of the drive motor 6; the screw 32 is rotatably connected to the housing 31; a telescopic rod 30 is disposed on the side of the housing 31 away from the drive motor 6; the telescopic rod 30 is sleeved on the outside of the screw 32; the telescopic rod 30 is threadedly connected to the screw 32; the telescopic rod 30 is slidably connected to the inner wall of the housing 31; and the lower end of the telescopic rod 30 passes through the fixing plate 11 and is fixedly connected to the inner wall of the central hole.

[0046] The working principle and beneficial effects of the above technical solution are as follows:

[0047] When the mold is opened and closed, the drive motor 6 drives the telescopic rod 30 to move up and down reciprocally through the screw 32. The telescopic rod 30 drives the upper mold 4 to move up and down along the connecting guide rod 12 through the connecting plate 16 and the connecting rod 17. When the upper mold 4 moves up and down along the connecting guide rod 12, the connecting guide rod 12 plays a guiding role. The copper sleeve 13 is sleeved on the outside of the connecting guide rod 12. The upper mold 4 and the copper sleeve 13 slide in direct contact, reducing friction and facilitating the sliding of the upper mold 4.

[0048] The drive motor 6 drives the telescopic rod 30 to move the motion frame 15 and the upper mold 4 up and down along the connecting guide rod 12, precisely controlling the timing and distance of opening and closing between the upper mold 4 and the lower mold 5, improving the fullness of the filling inside the mold, improving the precision and quality of the molded products, and ensuring the quality and consistency of the molded products.

[0049] Example 3

[0050] Based on any one of Examples 1-2, such as Figure 1-3 As shown, a hydraulic pump 21 is fixedly installed on the right side of the lower frame 2. The output end of the hydraulic pump 21 is connected to the high-pressure injection mixing nozzle 20. A temperature controller 22 is installed inside the lower mold 5. The temperature controller 22 is fixedly connected to the lower mold 5 and electrically connected to the controller.

[0051] The working principle and beneficial effects of the above technical solution are as follows:

[0052] The high-pressure injection mixing nozzle 20 is connected to the hydraulic pump 21. The hydraulic pump 21 provides power for mixing the raw materials in the high-pressure injection mixing nozzle 20, ensuring uniform mixing of the raw materials and improving the injection efficiency. This is beneficial for improving the precision and quality of the molded products and ensuring the quality and consistency of the molded products.

[0053] The lower mold 5 is equipped with a temperature controller 22, which has heating and cooling functions, allowing for timely heating and cooling of the mold. When the mold is opened, fiber reinforcement material is laid in the mold cavity of the lower mold 5. When the mold is closed, the fiber reinforcement material is pressed tightly against the mold, and preheating treatment of the mold begins. This is beneficial for the fusion of the fiber reinforcement material and the raw material, improving the fiber content and performance of the product. During the pouring operation, the set temperature is maintained, which helps the poured raw material reach every corner of the mold cavity more quickly, improving the material uniformity and structural performance of the molded product. After pouring, during the mold closing and locking process, the mold is appropriately cooled, allowing the product in the mold cavity to quickly solidify. This enables the one-time molding of complex products with a smooth surface, requiring no secondary finishing.

[0054] Example 4

[0055] Based on any one of Examples 1-3, such as Figure 1-3 As shown, a sealing element 23 is provided on the side of the lower mold 5 near the upper mold 4. The sealing element 23 is fixedly connected to the lower mold 5. A vacuum pump 24 is fixedly provided on the left side of the lower frame 2. A control mechanism 25 is fixedly provided at the bottom of the lower mold 5. A vacuum channel 26 is provided on the side of the lower mold 5 near the control mechanism 25. The vacuum channel 26 connects the lower mold 5 and the vacuum pump 24. The vacuum pump 24 and the control mechanism 25 are electrically connected to the controller.

[0056] The working principle and beneficial effects of the above technical solution are as follows:

[0057] Before high-pressure injection of the raw material, the upper mold 4 is moved upward by 0.5-1mm via the motion mechanism 3; the vacuum pump 24 is turned on, and the control mechanism 25 controls the vacuum channel 26 to connect with the mold cavity, and the mold cavity is evacuated. When the vacuum degree in the mold cavity reaches a certain value, the control mechanism 25 controls the vacuum pump 24 to turn off, stopping the vacuuming of the mold, and the raw material is injected into the mold under high pressure. The mold is continuously and controllably heated. The mold is equipped with a professional sealing component 23 to ensure the fluidity of the raw material within a controllable range. After injection, the motion mechanism 3 moves downward to completely close the mold. The mixed raw material flows and fills the mold with the closing pressure and a certain vacuum degree. The pressure in the mold is uniformly transmitted through the fiber bundle to prevent the fiber from shifting direction during curing. This ensures that the fiber does not become disordered and also ensures a high injection speed, improving the material uniformity and structural performance of the molded product.

[0058] Example 5

[0059] Based on any one of Examples 1-4, such as Figure 4-7 As shown, a demolding mechanism is provided on the side of the lower mold 5 away from the upper mold 4. The demolding mechanism includes: a top plate 60; a demolding cavity 61 is provided on the side of the lower mold 5 away from the upper mold 4; the top plate 60 is provided inside the demolding cavity 61; the two sides of the top plate 60 are slidably connected to the inner wall of the demolding cavity 61; a hydraulic port 62 is provided on the right side of the lower mold 5; the hydraulic port 62 is provided on the upper and lower sides of the top plate 60; the hydraulic port 62 connects the demolding cavity 61 to the output end of the hydraulic pump 21; a plurality of ejector rods 63 are provided on the upper part of the top plate 60; the bottom of the ejector rods 63 is fixedly connected to the top plate 60; the top of the ejector rods 63 is flush with the upper surface of the lower mold 5; and the side of the ejector rods 63 is slidably connected to the lower mold 5.

[0060] The demolding mechanism further includes: a housing 64, which is disposed on the rear side of the lower mold 5. The bottom of the housing 64 is fixedly connected to the top of the lower mold 5. The upper mold 4 has a groove on the side near the housing 64, which is adapted to the housing 64. A push block 65 is disposed on the front side of the housing 64, which is slidably connected to the inner wall of the housing 64. Positioning members 66 are disposed on the left and right sides of the housing 64. One side of the positioning member 66 is fixedly connected to the inner wall of the housing 64, and the other side of the positioning member 66 has a sliding hole 67. A telescopic bracket 68 is disposed between the positioning member 66 and the push block 65. The telescopic bracket 68 is scissor-type. The top two ends of the telescopic bracket 68 are rotatably connected to the inner wall of the sliding hole 67 and the rear side of the push block 65, respectively. The bottom two ends of the telescopic bracket 68 are slidably connected to the inner wall of the sliding hole 67 and the rear side of the push block 65, respectively.

[0061] A push rod 69 is provided on the side of the lower mold 5 near the telescopic bracket 68. The top of the push rod 69 passes through the lower mold 5, the housing 64 and the bottom of the telescopic bracket 68 near the sliding hole 67 and is hinged. The bottom of the push rod 69 extends into the demolding cavity 61 and is fixedly connected to the upper surface of the top plate 60. The push rod 69 is slidably connected to the housing 64 and the lower mold 5.

[0062] The working principle and beneficial effects of the above technical solution are as follows:

[0063] Several ejector pins 63 are provided. The number and position distribution of ejector pins 63 are related to the wall thickness, structure and shape of the molded product. Hydraulic method is used for demolding to ensure that the molded product is subjected to uniform force during separation, and to avoid the problem of incomplete separation of the molded product from the lower mold 5 due to uneven force, which would reduce the quality.

[0064] After the mold cools, the motion mechanism 3 drives the upper mold 4 to separate from the lower mold 5, the mold slowly opens, and the product separates from the upper mold 4. Then, the product is demolded from the lower mold 5. A multi-way valve is installed between the hydraulic pump 21 and the hydraulic port 62 to ensure smooth flow of hydraulic oil between the hydraulic pump 21 and the demolding cavity 61. The hydraulic pump 21 pressurizes the hydraulic oil into the demolding cavity 61 through the lower hydraulic port 62. The top plate 60 moves towards the upper mold 4, pushing the ejector rod 63 to separate the product from the lower mold 5. Simultaneously, as the top plate 60 moves upward, the push rod 69 drives one end of the telescopic bracket 68 to move upward along the sliding hole 67. The lower end of the telescopic bracket 68 near the sliding hole 67 moves towards the upper end, and the telescopic bracket... The other end of the frame 68 extends toward the push block 65, causing the push block 65 to move toward the product. When the push block 65 contacts the product, it pushes the bottom of the product to separate from the top of the ejector pin 63. At the same time, it moves the product to the front of the lower mold 5, i.e., the direction in which the operator picks up the product. After being pushed to the designated position, the hydraulic pump 21 presses hydraulic oil into the demolding cavity 61 through the upper hydraulic port 62, controlling the top plate 60 and the ejector pin 63 to move downward and return to their original positions. While the top plate 60 moves downward, the push rod 69 moves downward, and the lower end of the telescopic bracket 68 near the sliding hole 67 moves downward. The telescopic bracket 68 pulls the push block 65 toward the inside of the housing 64. When it contacts the bottom of the sliding hole 67, all components return to their original positions.

[0065] By setting up a demolding structure, the product is separated from the lower mold 5 and the ejector pin 63, so that the product is moved away from the position of the lower mold 5 and pushed to the part removal position. On the one hand, the operator's hand will not be put between the upper mold 4 and the lower mold 5, reducing safety hazards. On the other hand, it is convenient for the operator to remove the part, speeding up the product production process and improving the production efficiency of compression molded products.

A pinion 77 is provided inside the internal gear 78. The pinion 77 is located on the side of the worm 75 away from the fixed plate 11. The pinion 77 and the internal gear 78 are rotatably connected to the inner wall of the rotating cavity 76. The pinion 77 meshes with the tooth groove on the inner side of the internal gear 78.

[0069] A rotating motor 79 is provided on the side of any of the pinions 77 away from the fixed plate 11. The rotating motor 79 is fixedly connected to the locking block 70. A rotating shaft 80 is provided at the output end of the rotating motor 79. The bottom of the rotating shaft 80 is fixedly connected to the rotating motor 79. The rotating shaft 80 is fixedly connected to the pinion 77 and the worm gear 75 from bottom to top. The top of the rotating shaft 80 is rotatably connected to the locking block 70. The rotating motor 79 is electrically connected to the controller.

[0070] The working principle and beneficial effects of the above technical solution are as follows:

[0071] When the mold is fully closed for cooling, the telescopic rod 30 of the motion mechanism 3 is fixed in position. The controller starts the rotary motor 79, and the rotating shaft 80 and the pinion 77 rotate. This drives the internal gear 78 to rotate, causing the other pinions 77 to rotate synchronously. At the same time, the rotating shaft 80 and the pinion 77 synchronously drive the worm gear 75 to rotate. The worm wheel 74, through the rotation of the worm gear 75, drives the threaded rod 72 to move along the slot 71 towards the telescopic rod 30 until the locking block 73 on the threaded rod 72 contacts the outer wall of the telescopic rod 30. The rotary motor 79 then shuts off, and the threaded rod 72 and the worm wheel 74 no longer rotate. The locking block 73 and the telescopic rod 30 remain locked, ensuring that the telescopic rod will not move, so that the position between the upper mold 4 and the lower mold 5 will not move, maintaining the closed state of the upper mold 4 and the lower mold 5, thereby maintaining a certain molding pressure inside the mold; when the mold has cooled down and needs to be opened, the controller controls the rotating motor 79 to start, the rotating shaft 80 and the pinion 77 rotate in opposite directions, and at the same time, the worm gear 74 drives the threaded rod 72 to move along the slot 71 inwards through the rotation of the worm 75, so that the locking block 73 separates from the outer wall of the telescopic rod 30, the locking state is released, and the mold is separated;

[0072] During the cooling process after the mold is fully closed, the motion mechanism 3 will cause slight movement of the upper mold 4 due to the thermal expansion and contraction of the workpiece inside the mold during the solidification process. This can lead to unstable molding pressure inside the mold. The locking mechanism, through the tight connection between the locking block 73 and the telescopic rod 30, keeps the positions of the upper mold 4 and the lower mold 5 locked, thus maintaining stable molding pressure inside the mold. Maintaining stable molding pressure ensures sufficient flow of the mixed raw materials, which is beneficial to improving the uniformity of the molded product material and structural performance, improving the precision and quality of the molded product, and ensuring the quality and consistency of the molded product. At the same time, by locking the locking block 70 and the telescopic rod 30, the output of the motion mechanism 3 during the cooling process is reduced, allowing the motion mechanism 3 to prepare for mold separation in advance and improve production efficiency.
