解、組立てに時間がかかる。[0003] As shown in FIG. 3, the conventional fixing to the mother die 1 and the nest 2 is performed by bolts 10 or the like perpendicular to the mold dividing surface 7. In addition, ensuring the positional accuracy of the matrix 1 and the nest 2
It is necessary to process the mother mold inner dimension 11 and the nest outer dimension 12 with an accuracy higher than that of the intermediate fit. If the positional accuracy of the matrix 1 and the insert 2 is unstable, the resulting molded product dimensions will not be stable. Also, since the nest 1 and the matrix 2 are more than the intermediate fit, it takes time to disassemble and assemble.

Also, the accuracy of the nesting position can be corrected from the outside of the mold, and the positioning of the nesting is performed in a state where the movable mold and the fixed mold are combined.

FIG. 1 is a cross-sectional view of a mold structure for fixing and positioning a matrix and a nest according to an embodiment of the present invention. The present invention relates to a mother die having a through screw hole 4 parallel to a mold dividing surface 7.
1, a nest 2 having an R-shaped concave shape 5, and a screw 3 having an R-shaped tip 6. As another embodiment, use of a ball plunger or the like instead of the screw 3 or use of a conical shape instead of the R-shaped 5 or 6 may be mentioned.

る。FIG. 2 is a cross-sectional view perpendicular to FIG. 1, and is a cross-sectional view of a mold structure for securing the nesting position accuracy from outside the mold when the movable mold and the fixed mold are combined. As shown in FIG. 2, the screw 3 can be operated from the outside of the mold, so that the position of the nest 2 can be corrected and fixed even when the movable mold 8 and the fixed mold 9 are combined. Therefore, 4
If the structure in which the positioning is performed by the screw 3 from the side is adopted, the positioning can be performed in a state where the nest 2 is inserted into the mother die and the movable die 8 and the fixed die 9 are aligned. This makes it possible to ensure the nesting position accuracy independent of the accuracy and state of the master block.
