Description

Technical Field

[0001] The utility model belongs to the technical field of RTM, and in particular relates to an anti-clogging RTM forming die. Background Art

[0002] RTM is a process in which a designed reinforcement material preform is placed in a mold cavity, and a low-viscosity resin is injected into the mold cavity under the action of pressure or vacuum or both. The resin completes the infiltration of the reinforcement material preform during the flow and filling process, and solidifies and forms a composite material component. A molding mold is required.

[0003] During the injection molding process, the existing molds are prone to blockage of the injection port due to the characteristics of the resin, which requires frequent manual cleaning with the help of external tools, which increases the intensity of the work and greatly reduces the efficiency of injection molding. Therefore, we provide an anti-blocking RTM molding mold. Utility Model Content

[0026] See also Figure 1-3 , an anti-clogging RTM molding mold, comprising a substrate 1 and an upper mold 3, see Figure 1 As shown, the bottom of the upper mold 3 is fixedly connected with a latch 10 on all sides. The shape of the latch 10 is cylindrical. By utilizing the compatibility of the latch 10 and the positioning hole 11, the upper mold 3 and the lower mold 2 can be quickly assembled, thereby improving the assembly efficiency. The top of the substrate 1 is fixedly connected with the lower mold 2. Figure 1 As shown, positioning holes 11 are provided on all sides of the top of the lower mold 2, and the number of the positioning holes 11 is four. The setting of the positioning holes 11 achieves the purpose of limiting, and further improves the stability of the lower mold 2 and the upper mold 3 when connected. An injection port is provided on the upper mold 3, and an L-shaped frame 4 is fixedly connected to the right side of the top of the upper mold 3. A motor 5 is fixedly installed on the top of the inner side of the L-shaped frame 4, and a connecting block 8 is fixedly connected to the output end of the motor 5. A rotating rod 6 is inserted into the inner wall of the connecting block 8, and a stirring blade 7 is fixedly connected to the surface of the rotating rod 6. The connecting block 8 is driven to rotate by the motor 5, and the rotating rod 6 is driven to rotate by the connecting block 8. The stirring blade 7 is driven to rotate by the rotating rod 6. The solidified raw material at the injection port can be scattered by the rotation of the stirring blade 7, so that it continues to flow, thereby preventing the injection port from being blocked.

[0027] See Figure 1 As shown, the front and rear ends of both sides of the base plate 1 are fixedly connected with thread blocks 13, and the inner wall of the thread block 13 is threadedly connected with a second bolt 12. Through the arrangement of the second bolt 12, the base plate 1 can be quickly disassembled and assembled at a specified position, which greatly improves the efficiency of disassembly and assembly. Figure 1 As shown, the outer side of the L-shaped frame 4 is fixedly connected with a power supply box, and the inner cavity of the power supply box is provided with a battery. Through the setting of the battery, the electrical equipment is powered to maintain the normal operation of the electrical equipment. Figure 1 As shown, an arc-shaped baffle is fixedly connected to the top of the upper mold 3 and located above the injection port, and the height of the arc-shaped baffle is five centimeters. The arc-shaped baffle is set to prevent the raw material from overflowing from the injection port during the rotation of the stirring blade 7, thereby causing waste.
