Description

Technical Field

[0001] The invention relates to the technical field of composite material processing, in particular to a hot and cold integrated common platform for composite material compression molding. Background Art

[0002] Composite material compression molding is a method of adding a certain amount of premix or prepreg into a metal mold and curing it by heating and pressurizing.

[0021] The present invention discloses a composite material compression molding cold and hot integrated common platform, which has the following beneficial effects:

[0022] 1. The hot and cold integrated common platform for compression molding of composite materials utilizes the first temperature control adjustment seat and the second temperature control adjustment seat to realize modular installation of molding tooling. The first temperature control adjustment seat and the second temperature control adjustment seat are both equipped with hot and cold adjustment units. The hot and cold adjustment units utilize the oil guide seat assembly, the delivery pipe and the temperature control pipe to form multiple connecting pipelines in the first temperature control adjustment seat and the second temperature control adjustment seat respectively. The multiple connecting pipelines can form multiple independent circulation systems. Injecting hot fluid and cold fluid into different circulation systems can realize hot and cold regulation requirements, thereby freely realizing the molding process requirements of thermosetting and thermoplastic composite materials.

[0023] 2. The hot and cold integrated common platform for composite material compression molding can be equipped with two connecting plates, two sealing plates and two cover plates, and two conveying pipes to set up two-in-two-out connecting pipes inside the first temperature control seat and the second temperature control seat, respectively, which means there are two inlets and two outlets. The outermost pipe at the inlet takes in oil from the mold temperature controller, and flows to the outer pipe at the outlet to discharge oil to the mold temperature controller. At the same time, the outermost pipe at the outlet takes in oil from the mold temperature controller, and the outer pipe at the inlet discharges oil to the mold temperature controller, forming two passages respectively. Since the two have the same flow rate and the same inner diameter of the pipe, the time taken to reach the middle of the platform is almost the same. In order to ensure the stable operation of the press without unbalanced load, the mold is placed in the middle of the platform, so the temperature of the mold changes evenly, which is convenient for product molding.

[0024] 3. The composite material compression molding hot and cold integrated shared platform is equipped with a modular oil guide seat assembly. The oil guide seat assembly is a component that connects different temperature control tubes, allowing the oil circuit to switch between different circulation systems. The modular design means that the oil guide seat assembly can be replaced and reconfigured to adapt to different operating requirements. When the two-way oil guide seat is replaced with a four-way oil guide seat, and with a four-way delivery pipe, a 4-in-4-out connecting pipeline is realized, with four inlets and four outlets. This design can provide more flow control and heating and cooling rate adjustment options. This arrangement is conducive to improving the uniformity of mold heating and cooling, and can quickly switch the pipeline configuration according to different heat exchange requirements, improving the adaptability and flexibility of the platform.
