されている。 Conventionally, as shown in Fig. 1, a heat foaming mold used for urethane molds has an integral structure consisting of an inner mold 1 made of aluminum and an outer mold 2 made of iron on the outside of this inner mold 1. What has been done is known. Therefore, this mold is lighter in weight than a mold made entirely of iron, and is resistant to pressure and heat during heating and foaming. but,
Since the outer peripheral surface of the inner mold 1 is evenly covered with iron material, the heating efficiency of the inner mold 1 is poor, making efficient mold production impossible, and a mold release agent must be used each time molding is performed. The troublesome work of applying the mold release agent to the inner mold 1 is necessary, and the mold release agent is consumed and is not economical.Moreover, the odor of the mold release agent is generated during heating and foaming, which worsens the working environment. is being induced.

1 and an outer mold 12, the inner mold 11 is made of a material that is lightweight and has good thermal conductivity, such as aluminum, and the outer mold 12 is made of a pressure-resistant material such as iron. These inner mold 11 and outer mold 12 are removably superimposed on each other. Said inner mold 1
Teflon 13 is baked in a layer on the molding surface 11a of the molding surface 11a, thereby forming a cavity 14 for heat foam molding. In addition, the outer mold 12
A large number of through holes 15, 15, . . . are bored in the hole. The through holes 15, 15... are punched by press working in the plate material before forming the predetermined shape of the outer mold 12, and by forming the punched material into the predetermined shape as shown in the figure, An outer mold 2 is formed.

る。 According to the embodiment configured as above,
After a foaming raw material such as urethane for foaming is injected into the cavity 14, the raw material is heated and foamed from the outside of the outer mold 12 as in the conventional method.
Since a large number of through holes 15 are bored in the inner mold 12, the inner mold 12 is heated directly through the through holes 15, 15, . . . , and efficient heating and foaming is performed. Moreover, Teflon 1 is applied to the molding surface 11a of the inner mold 11.
3 is applied in layers, so there is no need for a mold release agent like in the past. Also, although the current Teflon 13 has problems with durability, according to the present invention,
Since the inner mold 11 and the outer mold 12 are removable, it is of course possible to prepare the Teflon-treated inner mold 11 in advance and continue the heating foaming work by simply replacing the inner mold 11. Since the inner mold 11 is lightweight, Teflon 1
When regenerating Teflon 13, the inner mold 11 can be easily transported from a place where heating and foaming is performed to a place where Teflon 13 is regenerated, and Teflon regeneration processing can be performed quickly.

速な作業が行なえる。 Furthermore, in hot foam molding, the mold temperature when releasing the hot foamed product is 80 to 100°C, and the mold temperature when pouring the foaming stock solution must be controlled to 30 to 50°C. According to this method, since the inner mold 11 is configured to be detachable from the outer mold 12, first, after heating and foaming, the two-layer mold consisting of the inner mold 11 and the outer mold 12 is fixed, with the foamed molded product still inside. After being placed in the curing furnace for an hour, the foamed molded product is removed from the inner mold 11. Next, inner mold 1
By putting 1 into cold air or cold water, it can be cooled down to the injection temperature in a short time. In this case, since the inner mold 11 is lightweight and easy to transport, the work can be carried out quickly.
