Description

Technical Field

[0001] This utility model relates to the field of resin processing technology, and in particular to a thermoplastic resin-based composite material laminate molding device. Background Technology

[0002] Resin-based composite laminates are composite laminates with resin as the matrix. Commonly used resins include thermosetting unsaturated polyester, phenolic resin, amino resin, epoxy resin, and some thermoplastic resins. The reinforcing materials are mostly fibers and their fabrics, such as carbon fiber and glass fiber. Sheet materials such as wood and paper can also be used.

[0003] Resin-based composite laminates require compression molding during production. However, some current compression molding equipment lacks auxiliary components, which can cause the laminate to adhere tightly to the mold after molding, making it difficult for workers to unload the material. This not only increases the difficulty of unloading but also reduces the efficiency of unloading resin-based composite laminates. Utility Model Content

[0004] The purpose of this invention is to provide a thermoplastic resin-based composite material laminate molding device, which can solve the problem that the resin-based composite material laminate may be tightly attached to the mold after molding, making it difficult for workers to unload it.

[0009] Preferably, the heating box has a heating space inside, and fixed crossbars are fixedly installed on the inner walls of both sides of the heating box. Electric heating wires are wound around the outer walls of the fixed crossbars and are located in the heating space of the heating box. This arrangement facilitates the heating of the thermoplastic resin-based composite material layer and increases the plasticity of the thermoplastic resin-based composite material layer during molding.

A support plate 2 is fixedly installed on the top of the fixed base plate 1. A lower mold 8 is provided on the fixed base plate 1. The top plate 9 is located inside the lower mold 8. An electric telescopic rod 13 is provided on the fixed base plate 1. The electric telescopic rod 13 is used to drive the lower mold 8 to rise and fall. The heating box 4 is located on the support plate 2. An electric heating wire 7 is provided inside the heating box 4.

[0021] Furthermore, an electric push rod 3 is fixedly installed on the top of the support plate 2. The free end of the electric push rod 3 extends to the bottom of the support plate 2 and is fixedly installed with a heating box 4. A molding plate 5 is fixedly installed at the bottom of the heating box 4. A heating space is opened inside the heating box 4. Fixed crossbars 6 are fixedly installed on the inner walls of both sides of the heating box 4. An electric heating wire 7 is wound around the outer wall of the fixed crossbar 6. The electric heating wire 7 is located in the heating space on the heating box 4. This arrangement can heat the resin-based composite laminate during the molding process, so that the resin inside can be heated and melted, and the resin can be filled into the lower mold 8. This avoids the situation where insufficient pressure during molding causes gaps in the molded resin-based composite laminate, thereby improving the quality of the molded resin-based composite laminate.

[0022] Furthermore, a lower mold 8 is fixedly installed on the top of the fixed base plate 1, and a top plate 9 is slidably installed on the inner wall of the lower mold 8. A sliding rod 10 is fixedly installed on the bottom of the top plate 9, and one end of the sliding rod 10 extends to the bottom of the lower mold 8 and is fixedly installed with a lifting plate 11. The sliding rod 10 and the lower mold 8 are slidably installed.

After the resin-based composite material laminate is molded, the molded resin-based composite material laminate can be lifted up, which makes it easier for workers to unload the material and improves the efficiency of unloading.

[0023] Working principle: In use, the thermoplastic resin-based composite material layer is laid inside the lower mold 8 and located on the top plate 9. Then, the electric push rod 3 is started, which drives the molding plate 5 to descend. When the molding plate 5 descends, it presses the thermoplastic resin-based composite material layer inside the lower mold 8. During pressurization, the electric heating wire 7 is started. The heat generated by the electric heating wire 7 is transferred to the thermoplastic resin-based composite material layer through the molding plate 5 to heat the thermoplastic resin-based composite material layer. After heating, the thermoplastic resin-based composite material layer is formed. Then, after cooling, the electric push rod 3 is started to reset the molding plate 5.
