Embodiment 1

[0050] The invention provides a visual RTM mold capable of steplessly adjusting the thickness of the composite material sheet, the structure of which is as follows Figure 1 to Figure 6 shown, including:

[0051] Roller 1, frame 2, pouring device 3, upper template 4, lower template 5, gas spring 6, mold opening mechanism 7, cavity adjustment mechanism 8 and heating component 9.

[0052] Frame 2 is used to carry the weight of the entire RTM mold and fix the relevant parts of the RTM mold. In order to facilitate the movement, the bottom is provided with rollers 1 .

[0053] One end of the upper template 4 is connected with the frame 2 through a hinge, and the side of the upper template 4 is connected with the frame 2 by a gas spring 6 . During the push-out process of the gas spring 6, the upper template 4 opens upwards around the hinge. On the contrary, during the retraction process of the gas spring 6, the upper formwork 4 moves toward the lower formwork 5 around the hinge. ...

Abstract

The invention relates to a visual RTM mould capable of infinitely adjusting the thickness of a composite plate. Toughened glass (42) is embedded in an upper mold plate (4), and a lower mold plate (5) is fixed to a rack through a fixed part (51). A sliding part (52) is arranged in the fixed part (51), a linkage part (53) is fixed to the bottom surface of the sliding part (52), and a cavity regulating mechanism (8) used for driving the linkage part (53) and the sliding part (52) to move up and down is arranged on the linkage part (53). Glue injection holes (521) and glue discharge hole (522) are formed in the ) sliding part (52) and the linkage part (53). Runners (523) are formed around the upper end of a middle through hole, leading to a closed cavity, of the fixed part (51) and communicate with the glue injection holes (521). The visual RTM mould can infinitely adjust and control the thickness of the composite plate through the cavity regulating mechanism, and has the advantages of high precision, self locking function, etc. The toughened glass used in the upper mold plate is used as an observation window, so that a user can observe resin filling and flowing.

Description

technical field [0001] The invention relates to the field of composite material product molding, in particular to a visual RTM (Resin Transfer Molding, resin transfer molding) mold capable of steplessly adjusting the thickness of a composite material sheet. Background technique [0002] The resin transfer molding (Resin Transfer Molding, RTM) process is an advanced process for manufacturing high-performance fiber-reinforced composite materials. Advantages, so it has been widely used in aerospace and transportation fields. [0003] At present, in the RTM process, mold design and preparation are important factors affecting the RTM process, directly affecting the dimensional accuracy of sheet metal products, the resin filling path, and the filling time, thereby affecting the intrinsic quality of composite materials; at the same time, the RTM mold Quality is also directly related to product quality, production efficiency and mold life. [0004] The quality of composite sheet p...
