ものである。[Detailed Description of the Invention] The present invention relates to an improvement of a molding device for molding urethane resin, and more specifically, a molding recess 3 with an upward opening surrounded by a side wall 2 of a molding frame 1 for molding urethane resin. A silicone rubber mold 4 for molding a urethane resin molded product 7 is fixed therein, and a molded product take-out claw 5 is arranged on the side wall 2, and the molded product take-out claw 5 is attached to the side wall so as to rotate almost at right angles to the side wall 2. 2, the molded product take-out claw 5 is placed along the inner surface of the silicone rubber mold 4 that can protrude into the silicone rubber mold 4, and this locking claw 6 is molded within the silicone rubber mold 4. This relates to a mold device for molding urethane resin which is secured to the outer surface 8 of a urethane resin molded product 7.

寸法精度が悪いという欠点があつた。 Conventionally, for molding with a complex surface shape, a silicone rubber mold 4' is set in the mold frame 1', urethane resin is poured, foamed and cured, and taken out. The urethane resin molded product 7' is stuck together and cannot be easily removed. Therefore, the urethane resin molded product 7' was first taken out from the mold frame 1' together with the silicone rubber mold 4', and then the silicone rubber mold 4' was removed from the foam-cured urethane resin molded product 7'. In this case, if you force it, the silicone rubber mold 4' will tear at the corner, and the silicone rubber mold 4' must be removed from the mold 1', so the silicone rubber mold 4' cannot be fixed to the mold 1'. Therefore, it is not possible to prevent thermal expansion of the silicone rubber mold 4' due to reaction heat during foaming and curing of the urethane resin, resulting in a drawback that the dimensional accuracy of the urethane resin molded product 7' is poor.

がある。 The present invention will be described in detail below with reference to illustrated embodiments. The mold 1 has a molding recess 3 surrounded by side walls 2 on all sides, and a silicone rubber mold 4 having a predetermined inner surface shape is fitted and fixed in the molding recess 3.
The molded product take-out claw 5 is a plate-shaped claw body 9 with an L-shaped locking claw 6 protruding from it. The claw body 9 is rotatably supported on the side wall 2 by a hinge 10. Here, the portion of the claw body 9 that protrudes outward from the side wall 2 is the gripping portion 11, and the locking claw 6 of the claw body 9 is positioned inside the silicone rubber mold 4. When the urethane resin is filled into the silicone rubber mold 4 and foamed and hardened, the locking claws 6 bite into the outer surface 8 of the molded product 7 to lock it. After the molded product 7 has sufficiently hardened, the grip part 1
1 is pushed down and the molded product 7 is directly released from the silicone rubber mold 4 by this action. In this case, since the silicone rubber mold 4 is fixed in the molding recess 3 as described above, the molded product 7 can be directly released from the silicone rubber mold 4.
By simply pressing down the molded product 7 and rotating the molded product take-out claw 5, the molded product 7 can be easily taken out by lever action. Moreover, the locking claw 6 of the molded product extraction claw 5 that can protrude into the silicone rubber mold 4 is arranged along the inner surface of the silicone rubber mold 4, and the locking claw 6 is engaged with the outer surface of the urethane resin molded product 7. Therefore, the locking claw 6 of the molded product take-out claw 5 is locked to the inconspicuous outer surface of the urethane resin molded product 7, and the urethane resin molded product 7
The urethane resin molded product 7 can be taken out without affecting the shape etc. of the urethane resin molded product 7. Furthermore, since the silicone rubber mold 4 is fixed in the molding recess 3, even if the silicone rubber mold 4 receives reaction heat when the urethane resin foams and hardens, it will not expand and cause dimensional deformation. There is an advantage that molded products with high dimensional accuracy can be obtained.
