Description

Technical Field

[0001] The utility model relates to the technical field of material forming, in particular to a composite material rapid forming device. Background Art

[0002] Ceramic-matrix composites (CMCs) are a type of composite material composed of a ceramic matrix and various fibers. The ceramic matrix can be high-temperature structural ceramics such as silicon nitride and silicon carbide. These advanced ceramics offer excellent properties such as high-temperature resistance, high strength and stiffness, relatively low weight, and corrosion resistance. However, their fatal weakness is brittleness. When stressed, they can crack or even break, leading to material failure. Combining high-strength, highly elastic fibers with the matrix is ​​an effective method for improving the toughness and reliability of ceramics.

[0003] Existing ceramic-based composite materials require the use of molds during production and molding. Generally, only after one product is demolded can the next product be molded. However, during the demolding process, the molding equipment is in a shutdown state, and the utilization rate of the molding equipment is low, which reduces the molding efficiency. For this reason, we propose a composite material rapid prototyping equipment. Utility Model Content

After the molding is completed, the staff will restore the upper mold 2 to its original position. At this time, continue to pull the lower mold 1 to move, so that another lower mold 1 can be moved to the bottom of the upper mold 2, and the mold can be closed again. The lower mold 1 of the previous completed product just moves to above the push plate 9. The staff starts the first longitudinal electric push rod 8, which can drive the push plate 9 to move upward, compress the support spring 12, and the ejector column 10 can eject the molded product, which is convenient for product demoulding, so that the molding equipment can work continuously, reduce equipment downtime, and improve molding efficiency.
