ある。Therefore, as shown in FIG. 5, in consideration of the thickness of the skin material H, it is conceivable to change the shear edge clearance between the portion having the skin material H and the portion having no skin material H as a boundary. . However, if the clearance of the shear edge is changed between the part with the skin material H and the part without the skin material H as described above, if a slight deviation occurs when setting the skin material H, a burr is generated at the time of molding. Etc. may occur.

In a skin-integrated molding die for producing a molded product obtained by injecting and clamping the skin to partially form a skin material, a shear edge is formed in the first and second molds, and the shear edge is formed. The clearance is 0.03 to 0.05 mm in the part where the skin material is not arranged, and 5 to 20 mm in the position where the skin material is arranged from the part where the skin material is not arranged.
It is characterized by having a clearance of 0.4 mm to 0.6 mm to the position where the skin material is arranged.

Since the shear edge clearance is formed by gradually changing from the part where the skin material is arranged to the part where the skin material is not arranged, even if the skin material is misaligned, it does not immediately become a gap in the shear edge. Thus, it is possible to prevent the resin from forming burr from the gap.

Since no burr or the like is generated, the appearance becomes good.
