Description

Technical Field

[0001] This utility model relates to the technical field of composite surfboard manufacturing equipment, and in particular to a hot pressing device for manufacturing composite surfboards. Background Technology

[0002] In the actual production and processing of composite surfboards, a special hot press machine is usually required to perform hot pressing operations on the different substrates of the composite surfboard to ensure the connection strength between the substrates of each layer of the composite surfboard.

[0003] However, existing hot pressing machines for processing composite surfboards have certain shortcomings in practical applications. The main problem is that the existing hot pressing molds can only be used for one-to-one hot pressing of composite surfboards of the same model. When hot pressing of different models of composite surfboards is required, the operator needs to perform cumbersome disassembly and installation of the existing hot pressing molds, which affects the efficiency of the equipment's hot pressing processing switching. Therefore, there is an urgent need to solve this problem. Summary of the Invention

[0004] In view of this, the present invention provides a hot pressing device for manufacturing composite surfboards. The main technical problem to be solved is that existing equipment has low efficiency in switching production conditions for different processing types.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hot pressing device for manufacturing composite surfboards, comprising a worktable, a lower mold support structure, a hot pressing lower mold structure, and a hot pressing upper mold structure, wherein the lower mold support structure is installed on the upper end face of the worktable, the hot pressing upper mold structure is installed above the worktable, and the hot pressing lower mold structure is installed on the upper end face of the lower mold support structure;

[0006] The hot-pressing lower mold structure includes a limiting lower mold, a first assembly rod, a second spring telescopic rod, a first button, a first mating block, and a first slot. The first assembly rod is fixedly connected to the lower end face of the limiting lower mold, the second spring telescopic rod is fixedly connected to the inside of the first assembly rod, the first button is slidably connected to the inside of the first assembly rod, the first mating block is slidably connected to the inside of the first assembly rod, one end face of the first button and one end face of the first mating block are fixedly connected, and the first slot is formed inside the first assembly rod.

[0007] The lower mold support structure includes a support base, a first spring telescopic rod, a first groove, a first sliding block, a first locking rod, and a first assembly groove. The support base is installed on the upper surface of the workbench. The first groove is formed inside the support base. The first spring telescopic rod is fixedly connected inside the first groove. The first sliding block is slidably connected to the inner wall of the first groove. The first locking rod is fixedly connected to the outer wall of the first sliding block.

[0008] The outer wall of the first locking rod is slidably connected to the inner wall of the first locking groove, the outer wall of the first mating block is fitted to the outer wall of the first locking rod, and the outer wall of the first assembly rod is slidably connected to the inner wall of the first assembly groove.

[0009] By adopting the above technical solution, the lower limiting mold is designed to engage with the first locking rod slidably connected inside the support base via a first slot on the side of the first assembly rod. During installation, the first assembly rod is aligned with the first assembly slot on the support base and inserted. The arc-shaped end of the first assembly rod pushes the first locking rod, which was previously protruding from the first assembly slot, back into the first groove inside the support base. When the first assembly rod is fully inserted into the first assembly slot, the first locking rod is pushed out by the elastic force of the first spring telescopic rod, allowing it to enter the first slot, thus locking and fixing the lower limiting mold. When disassembly is required, pressing the first button compresses the second spring telescopic rod, causing the first mating block to move upwards. The arc-shaped edge design allows the first mating block to push the first locking rod back into the first groove, releasing the locking of the first assembly rod. This facilitates the removal and replacement of the lower limiting mold.

[0010] As a further description of the above technical solution: the hot-pressing upper mold structure includes a mounting base, a limiting upper mold, a second assembly rod, a second mating block, a third spring telescopic rod, and a second slot.

[0013] By adopting the above technical solution, the upper limiting mold is designed to engage with the second locking rod, which is slidably connected to the second locking rod inside the locking block, through the second slot opened on the side of the second assembly rod. During installation, the upper limiting mold is inserted by aligning the second assembly rod with the second assembly slot on the locking block. The arc-shaped end of the second assembly rod pushes the second locking rod, which was previously protruding from the second assembly slot, back into the second groove inside the locking block. When the second assembly rod is fully inserted into the second assembly slot inside the locking block, the second locking rod is pushed out by the elastic force of the fourth spring telescopic rod, thus pushing the second locking rod into the second slot and completing the installation and locking of the upper limiting mold. When disassembly of the upper limiting mold is required, pressing the second button compresses the third spring telescopic rod, causing the second mating block to move upwards. The arc-shaped edge design allows the second mating block to push the second locking rod back into the second groove, releasing the locking of the second assembly rod. This facilitates the removal and replacement of the upper limiting mold.

[0015] By adopting the above technical solution, when the second button is pressed, the second baffle set on the upper end face of the third spring telescopic rod can limit the spring on the outer wall of the third spring telescopic rod, so that the second button can be pushed out and reset under the elastic action of the spring on the third spring telescopic rod.

[0016] As a further description of the above technical solution: the lower end face of the second spring telescopic rod is fixedly connected to a first baffle, and the lower end face of the first baffle is fixedly connected to the upper end face of the first mating block.

[0017] By adopting the above technical solution, when the first button is pressed, the first baffle on the upper end face of the second spring telescopic rod can limit the spring on the outer wall of the second spring telescopic rod, so that the first button can be pushed out and reset under the elastic action of the spring on the second spring telescopic rod.

[0018] As a further description of the above technical solution: the outer wall of the upper limiting mold and the inner wall of the lower limiting mold are fitted together, and handles are fixedly connected to both sides of the outer wall of the lower limiting mold.

[0019] By adopting the above technical solution, the upper limiting mold and the lower limiting mold are fitted together, which can ensure that the upper limiting mold presses the composite surfboard tightly into the lower limiting mold for hot pressing.

[0023] By adopting the above technical solution, the pressure bearing is set to facilitate the rotation of the support seat on the worktable, and at the same time, it can bear the pressure generated by hot pressing, effectively reducing the impact on the output accuracy of the servo motor. The set servo motor can easily drive the lower mold support structure to rotate.

[0024] As a further description of the above technical solution: an assembly frame is fixedly connected to the upper end face of the workbench, a hydraulic push rod is installed on the upper end face of the assembly frame, the telescopic end of the hydraulic push rod is fixedly connected to the upper end face of the mounting base, a control panel is installed on the outer wall of the assembly frame, and the control panel is electrically connected to the hydraulic push rod and the servo motor.

[0027] Compared with existing technologies, this hot-pressing device for manufacturing composite surfboards features a limiting lower mold that engages with a first locking rod slidably connected inside a support base via a first locking groove on the side of the first assembly rod. During installation, the first assembly rod is aligned with the first assembly groove on the support base and inserted. The arc-shaped end of the first assembly rod pushes the first locking rod, which was previously protruding from the first assembly groove, back into the first groove inside the support base. When the first assembly rod is fully inserted into the first assembly groove, the first locking rod is pushed out by the elastic force of the first spring telescopic rod, entering the first locking groove and locking the limiting lower mold in place. When disassembly is required, pressing the first button compresses the second spring telescopic rod, causing the first mating block to move upwards. The arc-shaped edge design allows the first mating block to push the first locking rod back into the first groove, releasing the locking of the first assembly rod. This facilitates the removal and replacement of the limiting lower mold, enabling quick disassembly.

[0028] Compared with existing technologies, this hot-pressing device for manufacturing composite surfboards features a limiting upper mold that engages with a second locking rod slidably connected inside the locking block via a second slot on the side of the second assembly rod. During installation of the limiting upper mold, the second assembly rod is aligned with the second assembly slot on the locking block and inserted. The arc-shaped end of the second assembly rod pushes the second locking rod, which was previously protruding from the second assembly slot, back into the second groove inside the locking block. When the second assembly rod is fully inserted into the second assembly slot within the locking block, the second locking rod... The fourth spring telescopic rod is pushed out under its elastic action, causing the second locking rod to be pushed out into the second locking groove, thus completing the installation and locking of the upper limiting mold. When it is necessary to disassemble the upper limiting mold, the second button is pressed. The pressed second button will compress the third spring telescopic rod, causing the second mating block to move upward. The arc-shaped edge design allows the second mating block to push the second locking rod back into the second groove, thus releasing the locking state of the second assembly rod. At this time, it is convenient to take out the upper limiting mold for replacement, realizing the quick disassembly operation of the upper limiting mold.

[0029] The aforementioned beneficial effects enable the equipment to perform quick disassembly and reassembly of the upper and lower molds in hot pressing according to different processing requirements, greatly improving the processing adaptability of the equipment. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0043] Reference Figure 1-10 The present invention provides a hot pressing device for manufacturing composite surfboards, comprising a workbench 1, a lower mold support structure 4, a hot pressing lower mold structure 6, and a hot pressing upper mold structure 7. The lower mold support structure 4 is installed on the upper surface of the workbench 1, the hot pressing upper mold structure 7 is installed above the workbench 1, and the hot pressing lower mold structure 6 is installed on the upper surface of the lower mold support structure 4.

[0044] The hot-pressing lower mold structure 6 includes a limiting lower mold 62, a first assembly rod 64, a second spring telescopic rod 65, a first button 61, a first mating block 67, and a first slot 68. The first assembly rod 64 is fixedly connected to the lower end face of the limiting lower mold 62. The second spring telescopic rod 65 is fixedly connected to the inside of the first assembly rod 64. The first button 61 is slidably connected to the inside of the first assembly rod 64. The first mating block 67 is slidably connected to the inside of the first assembly rod 64. One end face of the first button 61 and one end face of the first mating block 67 are fixedly connected. The first slot 68 is formed inside the first assembly rod 64.

[0045] like Figure 5-7 As shown, the lower mold support structure 4 includes a support base 401, a first spring telescopic rod 409, a first groove 410, a first sliding block 411, a first locking rod 412, and a first assembly groove 405.

The lower limiting mold 62 is configured to engage with the first locking rod 412, which is slidably connected inside the support base 401, through the first locking groove 68 opened on the side of the first assembly rod 64. With this structural design, when the lower limiting mold 62 is installed, the first assembly rod 64 is aligned with the first assembly groove 405 on the support base 401 and inserted. The arc-shaped end of the first assembly rod 64 will push the first locking rod 412, which was pushed out of the first assembly groove 405, back into the first groove 410 inside the support base 401. When the first assembly rod 64 is fully inserted into the first assembly groove 405 inside the support base 401, the first locking rod 412 is pushed out under the elastic action of the first spring telescopic rod 409, so that the first locking rod 412 enters the first locking groove 68, thus completing the installation and locking of the lower limiting mold 62.

[0047] When the lower limiting mold 62 needs to be disassembled, the first button 61 is pressed. The pressed first button 61 will compress the second spring telescopic rod 65, causing the first mating block 67 to move upward. The arc-shaped edge design allows the first mating block 67 to push the first locking rod 412 back into the first groove 410, thus releasing the locking state of the first assembly rod 64. At this time, it is convenient to take out the lower limiting mold 62 for replacement.

[0048] like Figure 8-10 As shown, the hot-pressing upper mold structure 7 includes a mounting base 71, a limiting upper mold 72, a second assembly rod 76, a second mating block 74, a third spring telescopic rod 77, and a second slot 78. The limiting upper mold 72 is fixedly connected to the lower end face of the mounting base 71, the second assembly rod 76 is fixedly connected to the upper end face of the limiting upper mold 72, the third spring telescopic rod 77 is fixedly connected inside the second assembly rod 76, the second mating block 74 is slidably connected inside the second assembly rod 76, and the second slot 78 is opened inside the second assembly rod 76.

[0049] A lock cylinder structure 8 is installed on the upper end face of the mounting base 71. The lock cylinder structure 8 includes a lock block 81, a second sliding block 82, a fourth spring telescopic rod 83, a second mounting groove 84, a second recess 85, and a second locking rod 86. The lock block 81 is fixedly connected to the upper end face of the mounting base 71. The second mounting groove 84 is opened inside the lock block 81. The second recess 85 is opened inside the lock block 81. The fourth spring telescopic rod 83 is fixedly connected to the inside of the lock block 81. The second sliding block 82 is slidably connected to the inside of the second recess 85. The second locking rod 86 is fixedly connected to the outer wall of the second sliding block 82.

[0050] The outer wall of the second locking rod 86 is slidably connected to the inner wall of the second locking groove 78, the outer wall of the second locking rod 86 fits against the outer wall of the second mating block 74, and the outer wall of the second assembly rod 76 is slidably connected to the inner wall of the second assembly groove 84. The upper limiting mold 72 is provided and engages with the second locking rod 86 slidably connected inside the locking block 81 through the second locking groove 78 opened on the side of the second assembly rod 76. With this structural design, when the upper limiting mold 72 is installed, the second assembly rod 76 is aligned with the second assembly groove 84 on the locking block 81 and inserted. The arc-shaped end of the second assembly rod 76 will push the second locking rod 86 that was pushed out of the second assembly groove 84 back into the second groove 85 inside the locking block 81. When the second assembly rod 76 is fully inserted into the second assembly groove 84 inside the locking block 81, the second locking rod 86 is pushed out under the elastic action of the fourth spring telescopic rod 83, so that the second locking rod 86 is pushed out into the second locking groove 78, thus completing the installation and locking of the upper limiting mold 72.

[0051] When it is necessary to disassemble the upper limiting mold 72, the second button 73 is pressed. The pressed second button 73 will compress the third spring telescopic rod 77, which will drive the second mating block 74 to move upward. The arc-shaped edge design allows the second mating block 74 to push the second locking rod 86 back into the second groove 85, thus releasing the locking state of the second assembly rod 76. At this time, it is convenient to take out the upper limiting mold 72 for replacement.

[0052] like Figure 9 As shown, a second baffle 75 is fixedly connected to the upper end face of the third spring telescopic rod 77. The upper end face of the second baffle 75 is fixedly connected to the outer wall of the second mating block 74. A second button 73 is slidably connected inside the second assembly rod 76. The lower end face of the second button 73 is fixedly connected to the upper end face of the second mating block 74. When the second button 73 is pressed down, the second baffle 75 on the upper end face of the third spring telescopic rod 77 can limit the spring on the outer wall of the third spring telescopic rod 77, so that the second button 73 can be pushed out and reset under the elastic action of the spring on the third spring telescopic rod 77.

[0053] like Figure 6 As shown, a first baffle 66 is fixedly connected to the lower end face of the second spring telescopic rod 65, and the lower end face of the first baffle 66 is fixedly connected to the upper end face of the first mating block 67. When the first button 61 is pressed, the first baffle 66 on the upper end face of the second spring telescopic rod 65 can limit the spring on the outer wall of the second spring telescopic rod 65, so that the first button 61 can be pushed out and reset under the elastic action of the spring on the second spring telescopic rod 65.

[0054] The outer wall of the upper limiting mold 72 and the inner wall of the lower limiting mold 62 are fitted together. Handles 63 are fixedly connected to both sides of the outer wall of the lower limiting mold 62. The fit between the upper limiting mold 72 and the lower limiting mold 62 ensures that the upper limiting mold 72 firmly presses the composite surfboard into the lower limiting mold 62 for heat pressing. The handles 63 facilitate the disassembly and installation of the lower limiting mold 62.

[0055] like Figure 3 As shown, the support base 401 has an internal mounting groove 408, and a spring push rod 407 is fixedly connected inside the mounting groove 408. A pressure sensor 406 is installed inside the spring push rod 407. The upper end face of the pressure sensor 406 is in contact with the lower end face of the limiting upper mold 72. A partition plate 404 is fixedly connected to the upper end face of the support base 401. The mounting groove 408 inside the support base 401 facilitates the installation of the spring push rod 407. The pressure sensor 406 installed on the upper end of the spring push rod 407 can detect the pressure parameters during hot pressing in real time. The spring push rod 407 can lift the composite surfboard processed in the limiting lower mold 62 for demolding after the hot pressing process is completed. The partition plate 404 can separate the pair of limiting lower molds 62 on the support base 401, so that hot pressing is performed on one side and loading and unloading are performed on the other side.

[0056] like Figure 4 As shown, a pressure bearing 403 is installed on the lower end face of the support base 401. The lower end face of the pressure bearing 403 is fixedly connected to the upper end face of the worktable 1. A servo motor 402 is installed inside the worktable 1, and the output end of the servo motor 402 is fixedly connected to the lower end face of the support base 401. The pressure bearing 403 facilitates the rotation of the support base 401 on the worktable 1 and also bears the pressure generated by hot pressing, effectively reducing the impact on the output accuracy of the servo motor 402. The servo motor 402 facilitates the rotation of the lower mold support structure 4.

[0057] like Figure 1 As shown, an assembly frame 2 is fixedly connected to the upper surface of the workbench 1. A hydraulic push rod 3 is mounted on the upper surface of the assembly frame 2. The telescopic end of the hydraulic push rod 3 is fixedly connected to the upper surface of the mounting base 71. A control panel 5 is mounted on the outer wall of the assembly frame 2. The control panel 5 is electrically connected to the hydraulic push rod 3 and the servo motor 402. The assembly frame 2 facilitates the installation of the hydraulic push rod 3, and the hydraulic push rod 3 facilitates the driving of the hot pressing upper mold structure 7 for hot pressing operation. The control panel 5 facilitates the control of the hydraulic push rod 3 and the servo motor 402.

[0058] Working principle: When the equipment is in actual use, if a hot pressing process is required for a specific composite surfboard, the operator can take out the upper limiting mold 72 corresponding to the current processing requirements, align the second assembly rod 76 on the lower side of the upper limiting mold 72 with the second assembly groove 84 opened on the locking block 81 and insert it. The second assembly rod 76 with the arc-shaped end design will push the second locking rod 86, which was pushed out of the second assembly groove 84, back into the second groove 85 inside the locking block 81. When the second assembly rod 76 is fully inserted into the second assembly groove 84 inside the locking block 81, the second locking rod 86 is pushed out under the elastic action of the fourth spring telescopic rod 83, so that the second locking rod 86 is pushed out into the second locking groove 78, thus completing the installation and locking of the upper limiting mold 72.

[0059] The operator can take out the lower limiting mold 62 corresponding to the current processing requirements, align the first assembly rod 64 on the lower side of the lower limiting mold 62 with the first assembly groove 405 on the support base 401 and insert it. The first assembly rod 64 with the arc-shaped end will push the first locking rod 412 that was pushed out in the first assembly groove 405 back into the first groove 410 inside the support base 401. When the first assembly rod 64 is fully inserted into the first assembly groove 405 inside the support base 401, the first locking rod 412 is pushed out under the elastic action of the first spring telescopic rod 409, so that the first locking rod 412 enters the first locking groove 68, completing the installation and locking of the lower limiting mold 62, thus completing the installation and fixing of the lower limiting mold 62.

[0060] After completing the above operations, the operator places the composite surfboard to be processed into the lower limiting mold 62. Then, the operator controls the lower limiting mold 62 and the upper limiting mold 72 to be electrically heated through the control panel 5, and controls the hydraulic ejector rod 3 to be ejected through the control panel 5, driving the hot pressing upper mold structure 7 to be pressed down as a whole, so that the upper limiting mold 72 is pressed into the lower limiting mold 62, and the composite surfboard in the lower limiting mold 62 is hot pressed together. After the hot pressing operation is completed, the hydraulic ejector rod 3 will retract, driving the hot pressing upper mold structure 7 to move up. Then, the operator controls the servo motor 402 to work through the control panel 5, driving the lower mold support structure 4 to rotate 180° as a whole. The processed composite surfboard is demolded under the ejection action of the spring ejector rod 407, making it easy to take out the composite surfboard in the lower limiting mold 62 and put the composite surfboard to be processed into the lower limiting mold 62.

[0061] When it is necessary to replace the lower limiting mold 62 and the upper limiting mold 72 again, the operator can press the first button 61. Pressing the first button 61 will compress the second spring telescopic rod 65, causing the first mating block 67 to move upward. The arc-shaped edge design allows the first mating block 67 to push the first locking rod 412 back into the first groove 410, thus releasing the locking state of the first assembly rod 64. At this time, it is convenient to take out the lower limiting mold 62 for replacement. The operator can press the second button 73. Pressing the second button 73 will compress the third spring telescopic rod 77, causing the second mating block 74 to move upward. The arc-shaped edge design allows the second mating block 74 to push the second locking rod 86 back into the second groove 85, thus releasing the locking state of the second assembly rod 76. At this time, it is convenient to take out the upper limiting mold 72 for replacement.
