Embodiment 1

[0050] The present invention provides a visible RTM mold capable of steplessly adjusting the thickness of composite material sheets, and its structure is as Figure 1 to Figure 6 Shown, including:

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

[0052] The frame 2 is used to carry the weight of the entire RTM mold and fix the related parts of the RTM mold. In order to facilitate the movement, a roller 1 is provided at the bottom.

[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. When the gas spring 6 is pushed out, the upper template 4 is opened up around the hinge. On the contrary, during the retracting process of the gas spring 6, the upper template 4 moves toward the lower template 5 around th...

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 visible RTM (Resin Transfer Molding) mold capable of steplessly adjusting the thickness of composite material sheets. Background technique [0002] Resin Transfer Molding (RTM) process is an advanced process for manufacturing high-performance fiber reinforced composite materials. It has low cost, fast molding speed, good product quality, low environmental pollution, and the ability to manufacture large and complex structural components. Advantages, so it has been widely used in the aerospace and transportation fields. [0003] At present, in the RTM process, mold design and preparation are important factors that affect the RTM process, directly affecting the dimensional accuracy of the sheet product, the resin filling path, and the filling time, thereby affecting the internal quality of the composite material; at the same time, the RTM mold Quality is also directly r...
