Background Technology

[0002] As we all know, handrails are an indispensable part of public construction. For example, handrails are needed in restrooms in shopping malls and hospitals, public corridors on ships, and activity areas for the disabled. However, existing handrails are generally made of metal, with flanges welded to both ends. The handrail is connected to the installation location by bolts passing through the flanges. After the flanges are welded to the ends of the metal handrails, the overall weight is very heavy, and the labor intensity during transportation is high. In order to reduce the strength of the metal, a very thin hollow structure is used, which is easily deformed after impact. Moreover, metal handrails installed on ships are particularly prone to corrosion, affecting their strength and service life. Metal handrails are especially cold to the touch in winter, resulting in poor comfort. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a carbon fiber integrated handrail and pressing mold that is simple in structure, made of carbon fiber, lightweight, easy to install, stable in connection, long in service life, comfortable to hold, efficient in molding, and has good molding effect.

At both ends of the opening of the lower n-shaped forming groove 7, the lower mold plate 6 has plate-shaped connecting flange outer grooves 8 communicating with the lower n-shaped forming groove 7. The lower mold plate 6 on both sides of the lateral connecting portion of the lower n-shaped forming groove 7 has lateral sliding grooves 9. At both ends of the lateral sliding grooves 9, there are locking sliders 10. The outer ends of the locking sliders 10 are symmetrically provided with vertical forming grooves 11 corresponding to the vertical portion of the lower n-shaped forming groove 7. The locking sliders 10 at the upper end of the vertical forming grooves 11 have grooves corresponding to the vertical forming grooves 11. The inner groove 12 of the connecting flange and the outer groove 8 of the connecting flange are combined to form the forming groove of the connecting flange. The lower part of the upper template 5 is provided with a mating protrusion 13. The lower end surface of the mating protrusion 13 is provided with an upper transverse groove 14 that cooperates with the transverse part of the lower n-shaped forming groove 7. The upper templates on both sides of the mating protrusion are provided with pressure plate surfaces 15 that press against the forming groove of the connecting flange. After the upper template 5 and the lower template 6 are closed, the two ends of the mating protrusion 13 are respectively mated with the inner side of the two snap-fit ​​sliders 10. The lower n-shaped forming groove 7, the outer groove 8 of the connecting flange, the inner groove 12 of the connecting flange, the upper transverse groove 14, and the pressure plate surface 15 are combined to form the carbon fiber integrated connecting handrail forming cavity.

[0021] Furthermore, the inner end side of the snap-fit ​​slider 10 is provided as an inwardly inclined surface 16 that is inclined towards the lower inner side. The two ends of the mating protrusion 13 below the upper template 5 are respectively provided with an outwardly inclined surface 17 that cooperates with the inwardly inclined surface 16 of the inner end side of the snap-fit ​​slider 10. The mating protrusion 13 tightly snaps the snap-fit ​​slider 10 into the vertical part of the lower n-shaped forming groove 7 of the lower template 6 through the cooperation of the inwardly inclined surface 16 and the outwardly inclined surface 17.

[0022] Furthermore, the lower template 6 has a fixed protruding guide post 18, and the upper template 5 has a guide hole 19 that cooperates with the guide post 18.

[0024] In the molding process of this utility model of carbon fiber integrated handrail, firstly, a foamed inner core 1 is made. After the foamed inner core 1 is made, carbon fiber prepreg is laid in the lower n-shaped molding groove 7 of the lower template 6. Then, the foamed inner core 1 is placed in the lower n-shaped molding groove 7 with the carbon fiber laid in place. Then, the exposed part of the foamed inner core 1 is covered and wrapped with the carbon fiber prepreg. After wrapping, two snap-fit ​​sliders 10 are placed on the lower template 6 and slid to the vertical part of the lower n-shaped molding groove 7 to align. The outer groove 8 and inner groove 12 of the connecting flange after alignment are combined to form the connecting flange molding groove. The connecting flange plate 3 of carbon fiber prepreg is arranged in the connecting flange molding groove. Then, the upper template 5 is lowered and the mold is closed. After the mold is closed, the lower n-shaped molding groove 7 below the mating protrusion 13 of the upper template 5 is fastened to the horizontal part of the lower n-shaped molding groove 7 and the wrapped carbon fiber prepreg is snapped in place. The outward inclined slopes at both ends of the mating protrusion 13 are extruded. The inward inclined surface of the snap-fit ​​slider 10 tightly snaps the snap-fit ​​slider 10 into the vertical part of the lower n-shaped forming groove 7, thereby completing the mold closing. After pressing and forming, the upper template 5 is demolded upwards, and the snap-fit ​​slider 10 is moved inwards to be removed. Then the formed product can be taken out.
