Description

Technical Field

[0001] The present invention relates to the technical field of motorcycle accessory processing, and particularly relates to an injection molding device for motorcycle accessories processing. Background Art

[0002] A motorcycle is a two-wheeled or three-wheeled vehicle driven by a gasoline engine and steered by a handlebar to turn the front wheel. It is light, flexible, and travels quickly. It is widely used for patrol, passenger and cargo transportation, etc., and is also used as a sports equipment. There are many accessories in the production process of motorcycles, such as the lamp housing, front apron, instrument panel, exhaust, and some other cover parts of the motorcycle.

[0003] During the production process of the instrument panel, hot pressing treatment is required. Generally, glue is coated at the joint between different materials. Before the glue dries, the instrument panel board is placed between the sandwich layers of the hot pressing equipment, and the instrument panel is hot pressed by the hot pressing plate to solidify the glue and tightly bond different materials together. However, when the glue is coated, generally the strip brushing or dotting method is used. When the two-layer material boards are aligned and fitted, there are gaps between the glue strips. Since the instrument panel generally has a large area, it is difficult to discharge the air by the direct pressing method. The air in the gaps will affect the gluing effect and cause cavities to appear after different material boards are glued, resulting in a low yield rate of the instrument panel. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that air exists between the instrument panel materials during the gluing of the instrument panel in the prior art, which affects the production quality of the instrument panel, and to propose an injection molding device for motorcycle accessories processing.

[0005] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0006] An injection molding device for motorcycle accessories processing includes an upper mounting plate and a lower mounting plate. The upper mounting plate and the lower mounting plate are fixedly connected by a connecting plate to form a rectangular frame structure. A plurality of bearing plates are arranged between the upper mounting plate and the lower mounting plate. An equidistant lifting mechanism is arranged between the plurality of bearing plates. A vertically arranged hydraulic cylinder is fixedly arranged on the bottom surface of the upper mounting plate. The telescopic end of the hydraulic cylinder is fixedly connected to the uppermost bearing plate. The lowermost bearing plate is fixed on the lower mounting plate. A heating plate for hot pressing the instrument panel is fixedly arranged below the bearing plate. Two cross-set pressing rods are rotatably arranged on both sides of the bearing plate. An installation shaft is rotatably arranged between two pressing rods on different sides. A smoothing roller for smoothing the composite instrument panel is rotatably sleeved on the installation shaft. A limiting mechanism for restricting the horizontal movement of the installation shaft is arranged between the upper mounting plate and the lower mounting plate.

[0007] Preferably, an installation groove is formed in the top surface of the bearing plate, and the thickness of the installation groove is the same as that of the instrument panel.

[0008] Preferably, the equidistant lifting mechanism includes a shaft fixedly arranged on the side wall of the bearing plate, and two cross - arranged connecting rods are rotatably arranged on the shaft. The two ends of the two connecting rods are respectively rotatably connected to the end parts of the connecting rods on the adjacent bearing plates.

[0009] Preferably, a limiting block is fixedly arranged on the side wall of the bearing plate, a vertically - arranged limiting groove is formed on the side of the connecting plate close to the bearing plate, and the limiting block is slidably connected with the limiting groove.

[0010] Preferably, the length of the flattening roller is the same as the length of the installation groove.

[0011] Preferably, the limiting mechanism includes four limiting rods fixedly arranged between the upper mounting plate and the lower mounting plate. The same limiting piece is slidably arranged on the two limiting rods on the same side, and a limiting ring slidably connected with the limiting piece is fixedly arranged at the end of the mounting shaft.

[0012] Preferably, the limiting piece includes a connecting rod, and sleeves are fixedly arranged at both ends of the connecting rod. The sleeves are slidably connected with the limiting rods, and springs are arranged between the sleeves and the limiting ring.

[0013] Preferably, the rotating shafts of the two pressing rods on the same side of the same bearing plate are arranged away from the middle of the bearing plate, so that the pressing rods are in an inclined state.

[0014] Preferably, the flattening roller is a rubber roller.

[0015] The present invention has the following advantages compared with the prior art:

[0016] 1. The present invention controls the carrier plates to approach each other by setting hydraulic cylinders and carrier plates, and by the telescopic movement of the hydraulic cylinders, so that the heating plates arranged below the carrier plates are close to and fit with the adjacent carrier plates, and squeeze the instrument panel located on the carrier plates. By setting the pressing rods, mounting shafts and smoothing rollers, when the carrier plates approach each other, the two smoothing rollers first press against the middle position of the instrument panel. Since the pressing rods are inclined, as the hydraulic cylinders extend, the pressing rods move towards the outer edge of the instrument panel under force, and the connecting rods can slide up and down along the limiting rods through the cooperation of the collar and the limiting rods. Since the connecting rods cooperate with the limiting rings, the two pressing rods rotate outwards synchronously, driving the limiting rings and the smoothing rollers to move outwards, and under the action of the springs, a reverse force is applied to the mounting shafts. Therefore, under the thrust of the pressing rods and the reverse elastic force of the springs, the mounting shafts will generate a downward pressure, making the smoothing rollers closely adhere to the surface of the instrument panel. As the smoothing rollers move to the outer edge of the instrument panel, the air bubbles in the instrument panel are expelled outwards. Finally, the heating plates abut against the instrument panels on the carrier plates, enabling the instrument panels to be hot-pressed and formed, and by discharging the air existing between the rubber strips, the bonding effect of the instrument panels is improved, solving the problem that air exists between the instrument panels during gluing in the prior art, which affects the production quality of the instrument panels.

[0017] 2. The present invention forms a scissor lift structure by setting a plurality of carrier plates and the connecting rods arranged on the carrier plates, with the connecting rods at different carrier plates connected end to end, ensuring that the plurality of carrier plates can move synchronously and equidistantly. Multiple instrument panels can be respectively placed on different carrier plates, and by driving the carrier plate at the top by a hydraulic cylinder to move, the plurality of carrier plates are pressed together synchronously, improving the efficiency of hot-pressing and forming of the instrument panels.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0028] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0029] Refer to Figure 1-2 , an injection molding device for motorcycle parts processing, including an upper mounting plate 1 and a lower mounting plate 2. The upper mounting plate 1 and the lower mounting plate 2 are fixedly connected through a connecting plate 3 to form a rectangular frame structure. The connecting plate 3 is welded to the upper mounting plate 1 and the lower mounting plate 2 respectively to form a stable rigid structure. A plurality of carrier plates 5 are arranged between the upper mounting plate 1 and the lower mounting plate 2. By setting a plurality of carrier plates 5, multiple dashboard plates can be pressed simultaneously, improving the processing efficiency. An equidistant lifting mechanism is provided between the plurality of carrier plates 5. Through the equidistant lifting mechanism, the plurality of carrier plates 5 can be lifted and lowered synchronously to realize synchronous pressing of multiple dashboard plates.

[0030] Refer to Figure 2, the equidistant lifting mechanism includes a shaft fixedly arranged on the side wall of the bearing plate 5. Two cross - arranged connecting rods 10 are rotatably arranged on the shaft. The connecting rods 10 on the bearing plates 5 at the uppermost and lowermost positions are only provided with half - sections. The two ends of the two connecting rods 10 are respectively rotatably connected to the end parts of the connecting rods 10 on the adjacent bearing plates 5, forming a movable scissor - type telescopic structure. Through the scissor - type telescopic structure, during the movement of the bearing plate 5, all the bearing plates 5 can move synchronously and maintain an equal - spacing state, so that when the hot - pressing operation is carried out, the dashboard plates on multiple bearing plates 5 are uniformly stressed.

[0031] Refer to Figure 1 and 3 , a limiting block 11 is fixedly arranged on the side wall of the bearing plate 5. A vertically - arranged limiting groove 12 is formed on the side of the connecting plate 3 close to the bearing plate 5. The limiting block 11 is slidably connected with the limiting groove 12. The limiting groove 12 is a rectangular groove, and the limiting block 11 is a rectangular block with the same cross - section as the limiting groove 12. Through the cooperation of the limiting groove 12 and the limiting block 11, the bearing plate 5 is limited, so that the bearing plate 5 will not rotate when sliding along the height direction of the limiting groove 12, and multiple bearing plates 5 are kept parallel during the up - and - down movement.

[0032] Refer to Figures 4-6 , a vertically - arranged hydraulic cylinder 4 is fixedly arranged on the bottom surface of the upper mounting plate 1. The telescopic end of the hydraulic cylinder 4 is arranged downward. The telescopic end of the hydraulic cylinder 4 is fixedly connected to the uppermost bearing plate 5. When the hydraulic cylinder 4 expands and contracts, it drives the uppermost bearing plate 5 to move, and drives all the bearing plates 5 to move through the equidistant lifting mechanism. The lowermost bearing plate 5 is fixed on the lower mounting plate 2. A heating plate 6 for hot - pressing the dashboard is fixedly arranged below the bearing plate 5. When the bearing plates 5 approach each other to a certain extent, the heating plate 6 on the bottom surface of the bearing plate 5 abuts against the dashboard plate on the lower - placed bearing plate 5 to press - fit the dashboard plate. Through the heat generated by the heating plate 6, the dashboard plate is hot - pressed and formed. Two cross - arranged pressing rods 7 are rotatably arranged on both sides of the bearing plate 5. An installation shaft 8 is rotatably arranged between the two pressing rods 7 on different sides. A smoothing roller 13 for smoothing the composite dashboard is rotatably sleeved on the installation shaft 8. During the pressing - fit, the smoothing roller 13 and the pressing rods 7 move along with the bearing plate 5. The smoothing roller 13 first abuts against the surface of the dashboard plate. As the bearing plates 5 approach each other, the two pressing rods 7 start to rotate when pressed, so that the two smoothing rollers 13 roll from the middle to both sides on the surface of the dashboard plate, exhausting the air in the glue - filling gap inside the dashboard plate, improving the pressing - fit effect of the dashboard plate and the yield rate of the dashboard plate.

[0033] Referring to FIGS. 5-6, the rotation shafts of the two pressing rods 7 on the same side of the same carrier plate 5 are arranged away from the middle of the carrier plate 5, so that the pressing rods 7 are in an inclined state. Since the pressing rods 7 are inclined, when the flattening roller 13 presses against the surface of the instrument panel, an upward force is applied to the pressing rods 7, causing the pressing rods 7 to move towards the inclined side and driving the flattening roller 13 to move towards the edge of the instrument panel.

[0034] A limiting mechanism for restricting the horizontal movement of the mounting shaft 8 is provided between the upper mounting plate 1 and the lower mounting plate 2. Through the limiting mechanism, the pressing rods 7 on the same carrier plate 5 move horizontally in opposite directions when moving.

[0035] Referring Figures 6-8 , the limiting mechanism includes four limiting rods 14 fixedly arranged between the upper mounting plate 1 and the lower mounting plate 2. The four limiting rods 14 are all vertically arranged. The same limiting member 15 is slidably arranged on the two limiting rods 14 on the same side. The limiting member 15 is horizontally arranged. Since the limiting member 15 is slidably connected to the two limiting rods 14, the limiting member 15 can only slide along the length direction of the limiting rods 14, that is, the vertical direction. A limiting ring 16 slidably connected to the limiting member 15 is fixedly arranged at the end of the mounting shaft 8. Since the limiting member 15 is horizontally arranged and the two limiting rings 16 are slidably connected to the limiting member 15, the mounting shaft 8 can only slide along the length direction of the limiting member 15, that is, the horizontal direction, so that the two flattening rollers 13 keep moving in contact with the surface of the instrument panel.

[0036] Referring Figures 6-8 , the limiting member 15 includes a connecting rod 17. Sleeve rings 18 are fixedly arranged at both ends of the connecting rod 17. The sleeve rings 18 are slidably connected to the limiting rods 14. The connecting rod 17 is limited by the two sleeve rings 18, so that the connecting rod 17 can change its position as the mounting shaft 8 moves, keeping the heights of the two flattening rollers 13 the same. And a spring 19 is arranged between the sleeve ring 18 and the limiting ring 16. By arranging the spring 19, when the limiting ring 16 moves outward with the mounting shaft 8, the limiting ring 16 compresses the spring 19, and the spring 19 applies a reverse elastic force to the limiting ring 16, so that the flattening roller 13 is subjected to an oblique pressing force of the pressing rod 7 and at the same time is subjected to a reverse acting force of the spring 19. At this time, the flattening roller 13 will generate a downward force, so that the flattening roller 13 always presses against the surface of the instrument panel during the outward movement, which is beneficial to improving the extrusion effect of the air bubbles inside the instrument panel.

[0037] Referring Figure 3 , an installation groove 9 is formed on the top surface of the carrier plate 5. The thickness of the installation groove 9 is the same as the thickness of the instrument panel, which is beneficial to positioning the instrument panel placed on the carrier plate 5 and reducing the risk of the instrument panel being skewed.

[0038] Referring Figure 8, the smoothing roller 13 is a rubber roller. The rubber roller has a certain elasticity, which can reduce the risk of damage to the dashboard panel when the smoothing roller 13 rolls on the surface of the dashboard panel.

[0039] Refer to Figure 2 , the length of the smoothing roller 13 is the same as the length of the installation groove 9, so that the smoothing roller 13 can discharge the residual air bubbles in the entire dashboard panel at one time, improving the efficiency of exhausting air bubbles.

[0040] The specific working principle of the present invention is as follows:

[0041] During use, the hydraulic cylinder 4 is raised to the limit position to separate the plurality of bearing plates 5 from each other. The dashboard panel to be hot-pressed is placed in the installation groove 9. The heating plate 6 is started, and the hydraulic cylinder 4 is started to move the hydraulic cylinder 4 downward. The scissor lift structure formed by connecting the connecting rods 10 on different bearing plates 5 end to end enables the plurality of bearing plates 5 to move synchronously and maintain an equidistant state;

[0042] When the bearing plates 5 approach each other, the two smoothing rollers 13 first press against the middle position of the dashboard panel. Since the pressing rod 7 is inclined, as the hydraulic cylinder 4 extends, the pressing rod 7 moves outward toward the outer edge of the dashboard panel under force. And the connecting rod 17 can slide up and down along the limiting rod 14 through the cooperation of the collar 18 and the limiting rod 14. Since the connecting rod 17 cooperates with the limiting ring 16, the two pressing rods 7 rotate outward synchronously, driving the limiting ring 16 and the smoothing roller 13 to move outward. Under the action of the spring 19, a reverse force is applied to the mounting shaft 8. Therefore, under the thrust of the pressing rod 7 and the reverse elastic force of the spring 19, the mounting shaft 8 generates a downward pressure, making the smoothing roller 13 closely attached to the surface of the dashboard panel. As the smoothing roller 13 moves to the outer edge of the dashboard panel, the air bubbles in the dashboard panel are expelled outward. Finally, the heating plate 6 abuts against the dashboard panel on the bearing plate 5, causing the dashboard panel to be hot-pressed and formed, and improving the bonding effect of the dashboard by exhausting the air existing between the rubber strips.

[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
