Description

Technical Field

[0001] The utility model relates to the technical field of fiberboard processing, in particular to a compression molding device for fiberboard production. Background Art

[0002] Fiberboard is made of wood fiber or other plant fiber as raw materials, which is prepared by fiber preparation, applied with synthetic resin, and pressed into a board. It is then processed through advanced processing techniques such as high temperature pressurization and drying. Therefore, a compression molding device is required during the processing of fiberboard.

[0003] After searching, the existing Chinese patent announcement number is: CN219006395U, which provides a fiberboard compression molding device. This patent uses a hydraulic press to drive a pressing plate and a molding mold to perform high-intensity compression on the fiberboard, thereby improving the internal strength of the fiberboard and ensuring the structural strength of the fiberboard.

[0004] Although the above patent can compress the fiberboard, the above fiberboard compression molding device still has the following problems: the prior art fiberboard is to extrude the fiberboard raw material through a molding mold. At this time, the fiberboard is deformed after being extruded, so that the fiberboard will be squeezed against the inner wall of the bottom mold groove, thereby causing the fiberboard to fit tightly with the inner wall of the bottom mold groove. At this time, when the fiberboard compression molding is completed and the fiberboard needs to be taken out, since the fiberboard and the bottom mold fit tightly, it increases the difficulty for the staff to buckle out the fiberboard, affecting the processing efficiency of the fiberboard.

[0005] In view of the above problems, a new fiberboard compression molding device is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide a compression molding device for fiberboard production, which solves the problem in the background technology that when the fiberboard compression molding is completed and the fiberboard needs to be taken out, the fiberboard is tightly fitted to the bottom mold, which increases the difficulty for the staff to remove the fiberboard, thereby affecting the fiberboard processing efficiency.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a compression molding device for fiberboard production, comprising a base, a bottom mold is fixedly installed on the upper surface of the base, an ejector plate is slidably connected in the mold groove of the bottom mold, the outer surface of the ejector plate is in contact with the inner wall of the mold groove of the bottom mold, and a heating plate is inlaid on the bottom wall of the mold groove of the bottom mold. The interior of the base is hollow, a push rod is fixedly installed on the lower surface of the ejector plate, and the lower end of the push rod slides through the base, a U-shaped seat is fixedly connected to the bottom wall of the base, a rotating plate is rotatably connected between two vertical plates of the U-shaped seat, the lower end of the push rod is hemispherical, the lower end of the push rod contacts and slides with the upper surface of the rotating plate, and a control mechanism is provided on the base.

[0008] By adopting the above technical solution, by pressing down the side of the rotating plate away from the pushing rod, the rotating plate rotates in the clockwise direction, so that the rotating plate will generate a thrust on the pushing rod, so the pushing rod pushes the ejection plate to move upward, so that the fiberboard in the mold groove of the bottom mold can be ejected. This method can avoid the problem of the fiberboard being too tightly fitted to the inner wall of the mold groove during the compression molding process, which increases the difficulty of removing the fiberboard, reduces the difficulty for the staff to remove the fiberboard from the bottom mold, and improves the efficiency of fiberboard processing.

[0009] As a further description of the above technical solution: a bracket is fixedly installed on the upper surface of the base, a hydraulic press is fixedly installed on the bracket, the lower end of the telescopic rod of the hydraulic press slides through the bracket, and a top mold is fixedly installed on the lower end of the telescopic rod of the hydraulic press.

[0010] By adopting the above technical solution, the fiberboard is placed in the mold groove of the bottom mold, the hydraulic press is started, and the telescopic rod of the hydraulic press pushes the top mold to move to one side of the bottom mold, so that the top mold and the bottom mold are closed, thereby the fiberboard can be compression molded.

[0011] As a further description of the above technical solution: the control mechanism includes a support plate, which is fixedly mounted on the upper surface of the base, and the side surface of the support plate is rotatably connected to a first rotating shaft, a rotating disk is fixedly sleeved on the outer surface of the first rotating shaft, and a contact rod is fixedly connected to the outer surface of the rotating disk, and the other end of the contact rod is in contact with the top mold, and a second rotating shaft is fixedly connected to the side surface of the rotating disk, and the second rotating shaft is arranged on a side away from the center of the rotating disk, and a mounting plate is fixedly mounted on the side of the support plate, and an extrusion rod is slidably sleeved on the mounting plate, and the upper end of the extrusion rod is rotatably connected to a rotating push plate, and the upper side of the rotating push plate is rotatably sleeved on the outer surface of the second rotating shaft, and the lower end of the extrusion rod slides through the base and contacts with the upper surface of the rotating plate away from the push rod.

[0012] By adopting the above technical solution, the fiberboard compression-molded in the bottom mold can be automatically ejected during the upward displacement of the top mold without manual operation, further reducing the operating steps of the staff. When the rotating disk rotates counterclockwise, the rotating disk will generate a pulling force on the rotating push plate, so the rotating push plate pulls the extrusion rod to move upward.

[0013] As a further description of the above technical solution: a limiting plate is fixedly sleeved on the outer surface of the extrusion rod, a spring is fixedly connected between the lower surface of the limiting plate and the mounting plate, and the spring is movably sleeved on the outer surface of the extrusion rod.

[0014] By adopting the above technical solution, when the extrusion rod is displaced, an extrusion or pulling force can be simultaneously applied to the spring, so that the spring is stretched or contracted under the force.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] 1. The utility model provides a compression molding device for fiberboard production, which can automatically eject the fiberboard compression-molded in the bottom mold during the upward displacement of the top mold, without manual operation, further reducing the operating steps of the staff, and avoiding the problem of the fiberboard being too tightly attached to the inner wall of the mold groove during the compression molding process, which increases the difficulty of removing the fiberboard, reduces the difficulty for the staff to remove the fiberboard from the bottom mold, and improves the efficiency of fiberboard processing.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0024] Combination Figure 1 The utility model is a compression molding device for fiberboard production, comprising a base 1, a bracket 2 is fixedly installed on the upper surface of the base 1, a hydraulic press 3 is fixedly installed on the bracket 2, the lower end of the telescopic rod of the hydraulic press 3 slides through the bracket 2, a top mold 4 is fixedly installed on the lower end of the telescopic rod of the hydraulic press 3, a bottom mold 5 is fixedly installed on the upper surface of the base 1, and the bottom mold 5 and the top mold 4 are in the same vertical position,

[0025] When in use, the fiberboard is placed in the mold groove of the bottom mold 5, the hydraulic press 3 is started, and the telescopic rod of the hydraulic press 3 pushes the top mold 4 to move to one side of the bottom mold 5, so that the top mold 4 and the bottom mold 5 are closed, thereby the fiberboard can be compression molded.

[0026] Combination Figure 2 An ejector plate 6 is slidably connected to the mold groove of the bottom mold 5, and the outer surface of the ejector plate 6 is in contact with the inner wall of the mold groove of the bottom mold 5. A heating plate 7 is inlaid on the bottom wall of the mold groove of the bottom mold 5. The heating plate 7 is a known technology in the existing patent: CN219006395U, and no further elaboration is made here. In this embodiment, the ejector plate 6 is made of a material with high thermal conductivity, such as copper; therefore, when in use, the heating plate 7 is started to dissipate heat, and the heat is conducted to the fiberboard in the bottom mold 5 through the ejector plate 6, providing thermal energy support during the compression molding of the fiberboard, thereby accelerating the molding speed of the fiberboard, thereby improving the production efficiency of the fiberboard.

[0027] Specifically, the interior of the base 1 is hollow, and a pushing rod 10 is fixedly installed on the lower surface of the ejection plate 6. The lower end of the pushing rod 10 slides through the base 1, and a U-shaped seat 8 is fixedly connected to the bottom wall of the base 1. A rotating plate 9 is rotatably connected between the two vertical plates of the U-shaped seat 8. The lower end of the pushing rod 10 is hemispherical, and the lower end of the pushing rod 10 contacts and slides with the upper surface of the rotating plate 9. Therefore, when the fiberboard is compression-molded, the rotating plate 9 is pressed downward away from the side of the pushing rod 10 so that the rotating plate 9 rotates clockwise, so that the rotating plate 9 forms a thrust on the pushing rod 10. Therefore, the pushing rod 10 pushes the ejection plate 6 to move upward, so that the fiberboard in the mold groove of the bottom mold 5 can be ejected. This method avoids the problem of too tight fit between the fiberboard and the inner wall of the mold groove during the compression molding process, which increases the difficulty of removing the fiberboard, reduces the difficulty of the staff to remove the fiberboard from the bottom mold 5, and improves the efficiency of fiberboard processing.

[0028] Combination Figure 2 and Figure 3 A support plate 11 is fixedly installed on the upper surface of the base 1, and a first rotating shaft 12 is rotatably connected to the side of the support plate 11. A rotating disk 13 is fixedly sleeved on the outer surface of the first rotating shaft 12, and a contact rod 14 is fixedly connected to the outer surface of the rotating disk 13. The other end of the contact rod 14 contacts the top mold 4. When the top mold 4 moves upward, the top mold 4 will form a thrust on the contact rod 14, so that the contact rod 14 drives the rotating disk 13 to rotate clockwise. When the top mold 4 moves downward, the top mold 4 will form a pressure on the contact rod 14, so that the contact rod 14 drives the rotating disk 13 to rotate counterclockwise.

[0029] Specifically, a second rotating shaft 15 is fixedly connected to the side of the rotating disk 13, and the second rotating shaft 15 is arranged on a side away from the center of the rotating disk 13. A mounting plate 17 is fixedly installed on the side of the supporting plate 11. An extrusion rod 18 is slidably sleeved on the mounting plate 17. The upper end of the extrusion rod 18 is rotatably connected to a rotating push plate 16. The upper side of the rotating push plate 16 is rotatably sleeved on the outer surface of the second rotating shaft 15. The lower end of the extrusion rod 18 slides through the base 1 and contacts the upper surface of the rotating plate 9 away from the push rod 10. When the rotating disk 13 rotates clockwise, The rotating disk 13 will generate a thrust on the rotating push plate 16, so that the rotating push plate 16 pushes the extrusion rod 18 to move downward, so the extrusion rod 18 can push the rotating plate 9 to rotate in the clockwise direction. Therefore, through the above structure, the fiberboard molded in the bottom mold 5 can be automatically ejected during the upward displacement of the top mold 4 without manual operation, further reducing the operating steps of the staff. When the rotating disk 13 rotates counterclockwise, the rotating disk 13 will generate a pulling force on the rotating push plate 16, so the rotating push plate 16 pulls the extrusion rod 18 to move upward.

[0030] Specifically, a limiting plate 19 is fixedly sleeved on the outer surface of the extrusion rod 18, and a spring 20 is fixedly connected between the lower surface of the limiting plate 19 and the mounting plate 17. The spring 20 is movably sleeved on the outer surface of the extrusion rod 18. When the extrusion rod 18 is displaced, an extrusion or pulling force can be synchronously applied to the spring 20, so that the spring 20 is stretched or contracted under the force.

[0031] Working principle: by placing the fiberboard in the mold groove of the bottom mold 5, the hydraulic press 3 is started, and the telescopic rod of the hydraulic press 3 pushes the top mold 4 to move to one side of the bottom mold 5, so that the top mold 4 and the bottom mold 5 are closed, so that the fiberboard can be compression-molded. After the fiberboard is compression-molded, the hydraulic press 3 drives the top mold 4 to move upward. After the top mold 4 moves to the specified position, the top mold 4 will form a thrust on the contact rod 14, so that the contact rod 14 drives the rotating disk 13 to rotate clockwise, and the rotating disk 13 will form a thrust on the rotating push plate 16, so that the rotating push plate 16 pushes the extrusion rod 18 to move downward, so that the rotating plate 9 rotates clockwise, so that the rotating plate 9 will form a thrust on the push rod 10, so the push rod 10 pushes the ejection plate 6 to move upward, so that the fiberboard in the mold groove of the bottom mold 5 can be ejected.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
