Problems solved by technology

[0002] Composite materials refer to materials that are physically or chemically combined by two or more materials with different properties. Carbon fiber reinforced composite materials made of carbon fiber and resin have good tensile strength and corrosion resistance. In the prior art, the prepreg is molded, but during the molding process, the mold will heat the carbon fiber composite material to speed up the fusion of the resin and the carbon fiber. Since the resin will be liquefied after heating, the liquefied resin and the surface of the mold are fully Fitting, the resin solidified after the composite material is cooled will adhere to the surface of the mold, resulting in increased resistance when taking out the material, reducing the production speed of the composite material, and even when the composite material is bonded to the mold on both upper and lower sides, Opening the mold will cause the resin on the outside of the composite material to fall off and crack, which reduces the pass rate of the composite material

Embodiment 1

[0028] as attached figure 1 to attach Image 6 Shown:

[0029] The invention provides a carbon fiber reinforced composite material preparation machine, the structure of which includes a controller 1, a hydraulic press 2, and a die 3. The left end of the controller 1 is embedded and connected to the right side of the hydraulic press 2, and the upper end of the die 3 is connected to the hydraulic press 2. The lower side is embedded and connected. The press mold 3 includes a bottom mold 31, a guide column 32, a pressing device 33, and a hydraulic rod 34. The outer end of the bottom mold 31 is movably engaged with the outside of the guide column 32. The guide column 32 The outer side is movably engaged with the outer end of the pressing device 33 , and the lower side of the hydraulic rod 34 is welded to the upper side of the middle part of the pressing device 33 .

[0030] Wherein, the pressing device 33 includes a push rod 331, a die 332, and a protruding block 333, the lower s...

Embodiment 2

[0037] as attached Figure 7 to attach Figure 9 Shown:

[0038]Wherein, the bottom mold 31 includes a support base 311, a tension spring 312, and a female mold 313. The inner side of the support base 311 is embedded and connected with the outer side of the female mold 313. connected, the number of the tension springs 312 is two, and they are symmetrically distributed around the master mold 313, so that the tension springs 312 can pull up the master mold 313, which is beneficial to separate the bottom of the carbon fiber composite material from the master mold 313 open.

[0039] Wherein, the female mold 313 includes a fixed block 13a, a filter plate 13b, and an ejector block 13c. Outer clearance fits, and described filter plate 13b is vertically installed with fixed block 13a, and the diameter of the upper end of described ejector block 13c is less than the internal diameter of fixed block 13a bottom, makes ejector block 13c move upwards and the air of upper end is extruded...

Abstract

The invention discloses a carbon fiber reinforced composite material preparation machine which structurally comprises a controller, a hydraulic machine and a pressing die, the left end of the controller is fixedly connected with the right side of the hydraulic machine in an embedded mode, the upper end of the pressing die is fixedly connected with the lower side of the hydraulic machine in an embedded mode, an ejector rod can move downwards to eject a separator in a stamping die downwards, then a shrinking machine is started for shrinking, a supporting plate can enter a gap between a carbon fiber composite plate and a mold to separate the carbon fiber composite material from a protruding block fixed to a lower cushion block of the mold, the separation process is accelerated, the material taking speed after the completion of preparation is increased, the production efficiency is improved, a tension spring pulls an ejection block to move upwards, air in the female die is ejected out upwards in a moving process, the carbon fiber composite material attached to the upper side of a plate body is pushed out, the carbon fiber composite material attached to the outer side of a filter plate can be uniformly separated from the filter plate, resin at the outer side of the carbon fiber composite material is prevented from falling off and cracking, and the qualified rate of the carbon fiber composite material is improved.
