Embodiment Construction

[0015] After extensive and in-depth research, the inventor found for the first time that the ejection device can effectively and quickly release the film, so the resin transfer molding process cycle can be effectively shortened, and moreover, multiple injection through holes can be provided at the same time. Dispensing glue can achieve the purpose of short glue injection time. The present invention has been completed on this basis.

[0016] Preferably, the upper mold pressing plate device can be lifted to a certain position by a mold clamping machine slider when the mold is opened, and then the male mold is pulled up.

[0017] Preferably, the male mold has:

[0018] The top surface of a male mold;

[0019] Bottom surface of a male mold;

[0020] A diversion groove for diverting resin that is recessed downward from the top surface of the male mold and has a diversion groove surface;

[0021] An air guiding groove formed on the top surface of the male mold and having an air guiding groov...

Abstract

The invention relates to a resin transfer moulding mold for preparing a molded product and a resin transfer moulding molding system containing the mold, wherein the mold comprises an upper moulded board which can be fixedly connected with a mold closing machine and can be lifted to a certain position by the mold closing machine to pull up a male die when the mold is opened, the male die, a female die and an ejecting device which is equipped with one or more ejector rods capable of ejecting upwards to release the molded product from the mold. The mold and the molding system provided by the invention are convenient in mold closing, mold opening and demolding; injection time is short; and a problem of relatively long process periods of composite materials is resolved.

Description

Technical field [0001] The invention relates to a resin transfer molding mold, in particular to a composite resin transfer molding mold. The cavity can be pre-filled with a fiber-reinforced preform, and then the resin is injected into the cavity through a glue injection port. After curing and molding, a composite product is prepared. The present invention also relates to a resin transfer molding system including the resin transfer molding mold. Background technique [0002] In recent years, with the rapid development of the automobile industry and the demand for sustainable development of society, the use of new energy power and automobile lightweight has become the key technology to reduce fuel consumption and reduce environmental pollution, and it is also an important pursuit of international advanced automobile manufacturers. aims. Today, advanced carbon fiber composite materials, known for their light weight and high strength, are favored by international automobile manufac...
