Description

Technical Field

[0001] The present invention relates to the technical field of hot pressing forming, in particular to a basalt fiber grid hot pressing forming device. Background Art

[0002] In the field of fiber material processing, basalt fiber is widely used in various industries, including building reinforcement, automotive manufacturing, and aerospace, due to its excellent properties such as high strength, corrosion resistance, and high temperature resistance. Traditional basalt fiber mesh production relies primarily on manual layup and simple mechanical pressing, followed by heat treatment and curing. The most common forming device in this process uses a simple flat-plate hot press, which places a fiber cloth or fiber bundle between upper and lower molds, and applies heat and pressure to achieve fiber bonding and shaping.

[0003] Chinese patent publication number CN106346762B discloses a film hot press forming device, comprising a film carrier and a hot press module. The film carrier comprises a carrier plate and a lower heating plate, the carrier plate having a product-profiling portion with a plurality of vacuum adsorption holes on its surface. The hot press module comprises an upper pressing plate and an upper heating plate, the upper pressing plate having recesses corresponding to the product-profiling portion. The film to be formed is vacuum-adsorbed onto the surface of the product-profiling portion of the carrier plate, the upper and lower heating plates heat the film, and the hot press module presses the film carrier to form the film.

[0004] As mentioned in the above application, this traditional hot pressing forming method is mostly for plates (the overall structure is not easy to dislocate and deform), but there are certain defects in the production of basalt fiber mesh products. The traditional hot pressing forming method is to place the raw materials in a mold and achieve fiber bonding and molding by heating and applying pressure. However, for fiber mesh products, the product is a hollow structure. Due to the lack of an effective positioning mechanism to position the fiber mesh, the fiber mesh is prone to dislocation or deformation during the pressurization process, affecting the dimensional accuracy and structural stability of the finished product. If a positioning device is simply added to the mold to fix the fiber mesh, after the molding is completed, due to the limitations of the positioning mechanism, the mesh is often difficult to demold smoothly, which increases the difficulty of production and the complexity of subsequent processing. Summary of the Invention

A plurality of positioning holes distributed in an array are provided on the inner bottom plate of the groove, and an accommodating chamber is provided inside the lower mold, and the positioning mechanism is located in the accommodating chamber.

[0009] As a further description of the above technical solution: the positioning mechanism includes a base plate, a limiting protrusion is fixed on the upper surface of the base plate, and a number of strip plates are welded at equal intervals on the two side walls of the base plate along the length direction. A rotating shaft is rotatably connected in the accommodating chamber along the length direction, and a driving block is fixed on the rotating shaft. The driving block is semi-cylindrical, and one end of the strip plate is attached to the horizontal plane of the driving block.

[0010] As a further description of the above technical solution: there are a total of several limiting protrusions, and the several limiting protrusions are distributed in an array, corresponding one to one with the several positioning holes. The upper surface of the limiting protrusion is a contraction structure around the center protrusion to facilitate the passage of the fiber mesh hole, and the lower surface of the strip plate is welded with a first spring.

[0011] As a further description of the above technical solution: the linkage assembly consists of a first linkage mechanism and a second linkage mechanism, and the first linkage mechanism and the second linkage mechanism are used to synchronously drive the positioning mechanism to achieve restricted positioning of the basalt fiber grid located in the lower mold.

[0012] As a further description of the above technical solution: the first linkage mechanism includes a strip driving plate, which is inserted into the lower mold, and the bottom end of the strip driving plate extends into the accommodating chamber and fits on the horizontal surface of the driving block. A slider is welded on one side wall of the strip driving plate, and a second spring is welded on the lower surface of the slider. A limiting plate is welded on the inner wall of the accommodating chamber, and a sliding groove is provided on the outer wall of the limiting plate. The slider is slidably connected to the sliding groove, and a positioning protrusion for cooperating with the driving block is welded on the other side wall of the strip driving plate.

[0013] As a further description of the above technical solution: the second linkage mechanism includes a gear plate, a connecting shaft and a rack, the connecting shaft is welded and fixed to the two ends of the rotating shaft, the gear plate is welded and fixed on the connecting shaft, the rack is welded and fixed to the lower surface of the upper mold, the rack is meshed and connected with the gear plate, and the gear plate is driven to rotate by driving the rack up and down.

[0014] As a further description of the above technical solution: the external frame consists of two parallel support frames and a connecting frame fixed to the top of the two support frames with bolts, a supporting seat is welded between the two support frames and below the connecting frame, and the lower mold is bolted to the supporting seat.

[0015] As a further description of the above technical solution: the lower surface of the upper mold is provided with a rectangular protrusion used to cooperate with the groove, and rubber sealing pads are provided at both ends of the rectangular protrusion along the length direction. Fixed blocks are welded at both ends of one side wall of the upper mold along the length direction, and a driving mechanism is provided on the external frame.

A hydraulic telescopic rod is bolted to the driving seat, and the movable end of the hydraulic telescopic rod is fixedly connected to the fixed block.

[0016] Beneficial effects:

[0017] The basalt fiber mesh hot-pressing forming device provided by the present invention provides a accommodating chamber in the lower mold, and a positioning mechanism is movably provided in the accommodating chamber. In conjunction with the arrangement of the linkage assembly, when in use, when the upper mold and the lower mold are driven to close, the linkage assembly synchronously drives the positioning mechanism to restrict and position the basalt fiber mesh located in the lower mold, thereby preventing the fiber mesh from being easily dislocated or deformed during the pressurization process, thereby affecting the dimensional accuracy and structural stability of the finished product. Moreover, when the upper mold and the lower mold are driven to separate, the positioning mechanism automatically retracts into the preset accommodating chamber, thereby avoiding the problem that the fiber mesh is difficult to demold smoothly due to the limitation of the positioning mechanism, which increases the difficulty of production and the complexity of subsequent processing. In addition, the basalt fiber mesh hot-pressing forming device has a high degree of automation, does not need to provide a driving assembly for the positioning mechanism, and reduces cost and operational complexity.

[0018] Furthermore, the linkage assembly includes a first linkage mechanism and a second linkage mechanism. When driving the upper mold and the lower mold to close the mold, when the upper mold moves downward, the upper mold will drive the driving plate and the rack to move downward, and the downward movement of the rack will drive the gear plate to rotate. The rotation of the gear plate drives the rotating shaft to rotate, thereby realizing the operation of the driving positioning mechanism. At the same time, when the driving plate moves downward, it will push the driving block to rotate, and the rotation of the driving block will also drive the rotating shaft to move, thereby realizing the operation of the driving positioning mechanism. The positioning mechanism is synchronously driven by the first linkage mechanism and the second linkage mechanism, thereby overcoming the defect of using only the two ends of the gear plate to drive the rotating shaft to rotate, which causes the rotating shaft to be subjected to large force and easy to be damaged and deformed, thereby improving the stability of the positioning mechanism. Secondly, a positioning protrusion is provided on the first linkage mechanism, and when the driving block rotates 90 degrees, one end of the driving block will abut against the lower surface of the positioning protrusion, thereby limiting the driving plate, and then limiting the height of the upper mold to move downward, avoiding excessive clamping when the upper mold moves downward, causing extrusion damage to the upper and lower molds, thereby realizing limited support for the downward movement height of the upper mold.

[0029] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific diagrams. It should be noted that the embodiments and features in the embodiments of this application can be combined with each other unless they conflict.

[0030] Example 1

[0031] See also Figures 1-6 The embodiment of the present invention provides a technical solution: a basalt fiber grid hot pressing forming device, including an external frame 1, a lower mold 2 and an upper mold 3, and also includes a linkage component. A positioning mechanism 5 is provided in the lower mold 2, and a accommodating chamber 24 is opened inside the lower mold 2. The positioning mechanism 5 is located in the accommodating chamber 24, and the linkage component is transmission-connected with the positioning mechanism 5. When the upper mold 3 and the lower mold 2 are driven to close the mold, the linkage component synchronously drives the positioning mechanism 5 to limit the positioning of the basalt fiber grid located in the lower mold 2, so as to avoid the fiber grid being easily dislocated or deformed during the pressurization process, thereby affecting the dimensional accuracy and structural stability of the finished product, and when the upper mold 3 and the lower mold 2 are driven to separate the molds, the positioning mechanism 5 will automatically shrink into the preset accommodating chamber 24, thereby avoiding the problem that the fiber grid is difficult to demold smoothly due to the limitation of the positioning mechanism 5, which increases the production difficulty and the complexity of subsequent processing.

[0032] By providing a linkage component, when the upper mold 3 and the lower mold 2 are driven to close the mold, the linkage component synchronously drives the positioning mechanism 5 to limit the positioning of the basalt fiber grid located in the lower mold 2, and when the upper mold 3 and the lower mold 2 are driven to separate the molds, the positioning mechanism 5 will automatically shrink into the preset accommodating chamber 24, thereby avoiding the problem that the fiber grid is difficult to demold smoothly due to the limitation of the positioning mechanism 5, which increases the difficulty of production and the complexity of subsequent processing. It has a high degree of automation and does not require a driving component to be provided for the positioning mechanism 5, thereby reducing costs and operational complexity.

[0033] The positioning mechanism 5 includes a base plate 51, a limiting protrusion 52 is fixed on the upper surface of the base plate 51, and a number of strip plates 53 are welded at equal intervals on the two side walls of the base plate 51 along the length direction. A rotating shaft 55 is rotatably connected along the length direction in the accommodating chamber 24, and a driving block 56 is fixed on the rotating shaft 55. The driving block 56 is semi-cylindrical, and one end of the strip plate 53 is attached to the horizontal surface of the driving block 56.

[0034] There are several limiting protrusions 52, and the limiting protrusions 52 are distributed in an array, corresponding one to one with the positioning holes 22. The upper surface of the limiting protrusion 52 is a contraction structure around the center protrusion to facilitate passing through the fiber mesh hole. The lower surface of the strip plate 53 is welded with a first spring 54.

[0035] Specifically, when the basalt fiber grid to be formed is laid in the lower mold 2, and the fiber grid holes correspond one-to-one to the positioning holes 22 opened on the groove 21, the limiting protrusion 52 extends from the accommodating chamber 24 and the positioning hole 22 and enters the groove 21 opened on the lower mold 2, so that the limiting protrusion 52 extends from the mesh hole of the basalt fiber grid, thereby limiting the basalt fiber grid and avoiding the situation where the basalt fiber grid is easily dislocated or deformed during the pressurization process, affecting the dimensional accuracy and structural stability of the finished product.

[0036] Optionally, the limiting protrusion 52 and the base plate 51 are detachable structures, and the limiting protrusion 52 and the base plate 51 are optionally connected by a snap connection or a threaded connection. During actual use, different limiting protrusions 52 can be automatically selected according to the mesh size of the basalt fiber grid, thereby improving the actual use range of the basalt fiber grid hot pressing molding device.

[0037] The lower mold 2 is fixedly disposed in the external frame 1 , and the upper mold 3 is movably disposed in the external frame 1 , with the lower mold 2 being located directly below the upper mold 3 .

[0038] A groove 21 is provided at the center of the upper surface of the lower mold 2 . The side walls at both ends of the lower mold 2 are provided with inlet and outlet grooves 23 that are in communication with the groove 21 . The inner bottom plate of the groove 21 is provided with a plurality of positioning holes 22 distributed in an array.

[0039] Specifically, when the basalt fiber grid hot pressing forming device is used, the basalt fiber grid to be formed is first laid in the lower mold 2, and the fiber grid holes are made to correspond one to one with the positioning holes 22 opened on the groove 21. When the upper mold 3 and the lower mold 2 are driven to close the mold, the positioning mechanism 5 is synchronously driven by the linkage component to restrict the positioning of the basalt fiber grid located in the lower mold 2. The specific method is as follows: when the upper mold 3 is driven to move downward and close the mold with the lower mold 2, the linkage component drives the rotating shaft 55 to rotate, the rotating shaft 55 rotates, drives the driving block 56 to rotate, and the driving block 56 rotates to push the strip plate 53 upward. At this time, the first spring 54 is in a stretched state, and the strip plate 53 moves upward, thereby driving the basalt fiber grid to move upward. The plate 51 moves upward, driving the limiting protrusion 52 on the base plate 51 to extend from the positioning hole 22 and the fiber mesh hole, thereby realizing the positioning of the fiber mesh and preventing the fiber mesh from being easily dislocated or deformed during the pressurization process, affecting the dimensional accuracy and structural stability of the finished product. When the extrusion is completed, when the upper mold 3 and the lower mold 2 are controlled to separate, the linkage assembly will synchronously drive the rotating shaft 55 to rotate in the opposite direction, thereby driving the driving block 56 to rotate in the opposite direction. At this time, the strip plate 53 automatically moves downward under the pulling force of the first spring 54, driving the base plate 51 to move downward, so that the limiting protrusion 52 on the base plate 51 shrinks into the positioning hole 22, thereby not affecting the demolding of the formed fiber mesh and reducing its generation difficulty.

[0040] Example 2

[0041] See also Figure 4-Figure 7 Based on the above embodiments, this embodiment discloses a linkage assembly, which consists of a first linkage mechanism and a second linkage mechanism. The first linkage mechanism and the second linkage mechanism are used to synchronously drive the positioning mechanism 5 to achieve restricted positioning of the basalt fiber grid located in the lower mold 2.

[0042] The first linkage mechanism includes a strip drive plate 61, which is inserted into the lower mold 2. The bottom end of the strip drive plate 61 extends into the accommodating chamber 24 and fits on the horizontal surface of the drive block 56. A slider 611 is welded on one side wall of the strip drive plate 61, and a second spring 612 is welded on the lower surface of the slider 611. A limiting plate 57 is welded on the inner wall of the accommodating chamber 24, and a slide groove 58 is provided on the outer wall of the limiting plate 57. The slider 611 is slidably connected to the slide groove 58, and a positioning protrusion 601 for cooperating with the drive block 56 is welded on the other side wall of the strip drive plate 61.

[0043] In actual work, the applicant found that the hydraulic telescopic rod 42 inevitably has abnormalities, including the telescopic stroke of the hydraulic telescopic rod 42 exceeding the preset stroke, or being less than the preset stroke; these two abnormalities will affect the quality of the final product. Most of the time, when there is a problem with the quality of the final product, this abnormality can only be discovered through reverse investigation, which is a lag.

[0044] This embodiment further improves the solution. When the telescopic stroke of the hydraulic telescopic rod 42 exceeds the preset stroke, specifically, the working state of the first linkage mechanism is that when the upper mold 3 and the lower mold 2 are driven to close, the upper mold 3 moves downward, and the upper mold 3 drives the driving plate 61 to move downward. When the driving plate 61 moves downward, it pushes the driving block 56 to rotate, and the rotation of the driving block 56 also drives the rotating shaft 55 to rotate, thereby driving the positioning mechanism 5 to work, and when the driving plate 61 moves downward, it synchronously drives the slider 611 to move downward in the slide groove 58, driving the second spring 612 to contract. Therefore, when the upper mold 3 moves upward, Under the action of the rebound force of the second spring 612, the driving plate 61 will also be driven to move upward, and when the driving block 56 rotates 90 degrees, one end of the driving block 56 will abut against the lower surface of the positioning protrusion 601, thereby limiting the driving plate 61, and then limiting the downward movement height of the upper mold 3 (that is, the stroke when the driving block 56 rotates 90 degrees and abuts against the positioning protrusion 601 is equal to the downward movement stroke of the upper mold 3), avoiding excessive downward movement of the upper mold 3 and causing extrusion damage to the upper mold 3 and the lower mold 2, thereby realizing the limiting support of the downward movement height of the upper mold 3 to avoid affecting the quality of the final product.

[0045] When the stroke is less than the preset stroke, a pressure switch can be embedded in the abutting surface of the positioning protrusion 601 and the driving block 56. The pressure switch is used to control the circuit connectivity status of an alarm device (such as a flash light). The alarm device is powered by an external power supply. When the upper mold 3 moves downward, the driving block 56 rotates 90 degrees and does not abut against the positioning protrusion 601, the flash light circuit is connected and lights up. When the flash light does not light up, it reminds the staff that the telescopic stroke of the hydraulic telescopic rod 42 is insufficient.

[0046] The second linkage mechanism includes a gear plate 62, a connecting shaft 63 and a rack 64. The connecting shaft 63 is welded and fixed to both ends of the rotating shaft 55, the gear plate 62 is welded and fixed on the connecting shaft 63, and the rack 64 is welded and fixed to the lower surface of the upper mold 3. The rack 64 is meshed and connected with the gear plate 62, and the gear plate 62 is driven to rotate by moving the rack 64 up and down.

[0047] Specifically, in this embodiment, the positioning mechanism 5 is synchronously driven by the first linkage mechanism and the second linkage mechanism, thereby overcoming the defect that the rotating shaft 55 is driven to rotate by the two ends of the gear plate 62 alone, resulting in a large force on the rotating shaft 55 and easy damage and deformation.

[0048] On the basis of Example 1, when the basalt fiber grid to be formed is laid in the lower mold 2, and the fiber grid holes correspond one-to-one to the positioning holes 22 opened on the groove 21, when the upper mold 3 and the lower mold 2 are driven to close the mold, when the upper mold 3 moves downward, the upper mold 3 will drive the driving plate 61 and the rack 64 to move downward, and the downward movement of the rack 64 will drive the gear plate 62 to rotate, and the rotation of the gear plate 62 drives the rotating shaft 55 to rotate, thereby driving the positioning mechanism 5 to work, and at the same time, when the driving plate 61 moves downward, it will push the driving block 56 to rotate, and the rotation of the driving block 56 will also drive the rotating shaft 55 to rotate, thereby driving the positioning mechanism 5 to work, and when the driving plate 61 moves downward, it will synchronously drive the slider 611 to move downward in the slide groove 58, driving the second spring 612 to contract. Therefore, when the upper mold 3 moves upward, under the action of the rebound force of the second spring 612, the driving plate 61 will also be driven to move upward.

[0049] Example 3

[0050] See also Figure 1-Figure 2 and Figure 7-Figure 8 This embodiment specifically discloses an external frame 1 and a driving mechanism 4. The external frame 1 is composed of two parallel support frames 11 and a connecting frame 13 fixed to the top of the two support frames 11 with bolts. A supporting seat 12 is welded between the two support frames 11 and below the connecting frame 13. The lower mold 2 is bolted to the supporting seat 12.

[0051] The lower surface of the upper mold 3 is provided with a rectangular protrusion 32 used to cooperate with the groove 21. Rubber sealing gaskets 33 are provided at both ends of the rectangular protrusion 32 along the length direction. When in use, after the upper mold 3 moves down and fits with the lower mold 2, the rectangular protrusion 32 will enter the groove 21 opened on the lower mold 2, and cooperate with the setting of the rubber sealing gasket 33 to improve its sealing effect on the groove 21. The rubber sealing gasket 33 is made of a high-temperature resistant polymer heat-resistant rubber material.

[0052] Fixed blocks 31 are welded at both ends of one side wall of the upper mold 3 along the length direction. A driving mechanism 4 is provided on the external frame 1. The driving mechanism 4 includes a driving seat 41. The driving seat 41 is bolted to the external frame 1. A hydraulic telescopic rod 42 is bolted to the driving seat 41. The movable end of the hydraulic telescopic rod 42 is fixedly connected to the fixed block 31.

[0053] On the basis of the above embodiment, this embodiment further adds a driving mechanism 4, which is used to adjust the height of the upper mold 3 and automatically realize the mold separation and closing of the upper mold 3 and the lower mold 2. When in use, the height of the upper mold 3 is automatically adjusted by controlling the extension and retraction of the hydraulic telescopic rod 42.
