Description of the Related Art As a method for producing a fiber-reinforced reaction injection-molded article, a fiber-reinforced material is placed in a cavity of an injection-molding die consisting of a cavity die and a core, and a stock solution of a reactive resin composition is added to the die. A method is known in which the fiber reinforcing material is impregnated by injection into the cavity and is cured by reaction.

液を均一に含浸できなくなる。In order to improve performance such as mechanical strength of the molded product in the method for producing a fiber reinforced reaction injection molded product of this kind, a method of increasing the content of the fiber reinforced material is usually adopted. However, as the content of the fiber reinforcement increases (about 15% by weight or more), the resistance of the stock solution of the reactive resin composition flowing through the fiber reinforcement increases, especially from the injection hole (injection port) of the stock solution. The stock solution cannot be uniformly impregnated into the fiber reinforced material in the farthest portion.

が提案されている。In order to solve such a problem, Japanese Unexamined Patent Publication (Kokai) No. 215510/1990 discloses a fiber of a portion which is hard to be impregnated with a stock solution of a reactive resin composition before being injected into a cavity of a mold. A method has been proposed in which the reinforcing material is impregnated with the stock solution in advance.

クルが長くなり生産性が低下する。However, in the method proposed above, the fiber reinforced material impregnated with the undiluted solution becomes sticky or the undiluted solution drips, which deteriorates the workability of handling the fiber reinforced material. Further, since the undiluted solution reacts relatively quickly, the fibrous reinforcing material may harden and become unmoldable while being placed in the cavity of the mold. To avoid this,
The use of the undiluted solution with a slow curing reaction lengthens the molding cycle and lowers the productivity.

It is an object of the present invention to provide a method for producing a fiber-reinforced reaction injection-molded article having excellent properties such as strength.

る。[Means for Solving the Problems] The above object is to arrange a fiber reinforcing material in the cavity of an injection molding die comprising a cavity die and a core, and to prepare a stock solution of a reactive resin composition in the cavity of the die. In the method for producing a fiber reinforced reaction injection molded product by injecting into a fiber reinforced material and impregnating the fiber reinforced material, and reaction curing, a slide core is provided in a part of the cavity mold and / or the core, and the slide core is retracted. This can be achieved by causing the undiluted solution injected into the cavity to flow into the void formed in the slide core portion and then advancing the slide core to impregnate the fiber reinforced material with the undiluted solution in the void.

射出成形用金型と同じ構成である。Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory view showing a longitudinal section of one embodiment of the present invention. In FIG. 1, 10 is a mold for injection molding, 11 is a cavity mold, 12 is a core, 1
3 is a slide core, and 14 is an injection hole (injection port) for the stock solution. The injection molding die 10 includes a slide core 13
Is the same as that of the conventional hermetically-sealed type injection molding die except that.

構成されている。The slide core 13 is provided such that it can move forward and backward while sliding in the core 12 by a hydraulic cylinder, an air cylinder, or the like. The sliding clearance is 3/1 to prevent the low viscosity stock solution from entering.
It is preferable that the thickness is 00 mm or less. Then, with the slide core 13 retracted, a gap 15 is formed in the slide core portion.
Is formed, and the gap 15 is closed by the slide core 13 when the slide core 13 is advanced.

The position and the number of slide cores 13 are appropriately set in consideration of the shape and size of the fiber-reinforced reaction injection molded product to be obtained. In FIG. 1, the injection hole (injection port) 14 for the undiluted solution is provided at the bottom of the cavity mold 11, but in particular, the length direction of the void 15 formed in the slide core part is
It is preferably provided so as to be parallel to the injection direction of the stock solution injected into the 0 cavity.

形品は得られない。It is desirable that the area of the voids 15 of these slide cores 13 be close to the surface area of the fiber-reinforced reaction injection molded product to be obtained. However, without providing the slide core 13 at all, the entire core is slightly retracted to form a void in the entire mold, and when the stock solution is injected into the cavity and the mold is clamped in this state, the injection pressure of the stock solution causes A homogeneous fiber-reinforced reaction injection molded article cannot be obtained because the fiber-reinforced material is displaced or the fibers constituting the fiber-reinforced material move.

Usually, the mold clamping force is preferably 3 to 10 kg / cm 2 . At this time, the slide core 13 is retracted so that a gap 15 is formed between the slide core 13 and the fiber reinforcing material 16. As the fiber reinforcing material 16, a glass fiber mat such as a chopped strand mat or a continuous strand mat, a carbon fiber mat, or an organic fiber mat such as nylon is preferably used.

The stock solution injected into the cavity of the mold 10 is partially impregnated into the fiber reinforcing material 16 and a part of the stock solution flows into the void 15 formed in the slide core portion. After that, slide core 13
Is advanced with a pressure higher than the mold clamping force, the undiluted solution in the voids 15 is impregnated in the fiber reinforcing material 16, and the undiluted solution undergoes a curing reaction in this state. Then, the mold 10 is opened and demolded by a conventional method to obtain a fiber-reinforced reaction injection molded product.

Also, when a slide core is provided in a part of the core and the stock solution of the reactive resin composition is allowed to flow into the void formed between the slide core and the fiber reinforcing material in a state where the slide core is retracted, the fiber reinforcing is performed. Even if the content of the material is increased (about 15% by weight or more), the stock solution can easily and quickly reach the end through the inside of the fiber reinforced material due to the existence of the voids in the slide core.
