るように組合わせ可能な構成となつている。(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. In the drawing, 1 is a fixed platen of an injection molding machine, and a mold body 2 is mounted on the punch surface of the platen. The mold 3 is made by inserting and assembling the insert 4 into the mold body 2. The mold body 2 is provided with a nest mounting portion 5 having a lip groove-shaped cross section.
has an open upper end on the insert insertion side, a stopper 6 is formed at the lower end, and a guide rail 7 is formed in the opposing groove. On both sides of nest 4,
A protruding strip 8 is formed with narrowed upper and lower ends.The insert 4 is inserted into the insert mounting portion 5 by sliding the protruding strip 8 on the guide rail 7, and the insert tip 9 is inserted into the insert mounting portion 5.
By pressing the mold body 2 against the stopper 6, the mold body 2 and the insert 4 can be combined to form a surface molding part of an injection molded product.

れている。 In order to position the insert 4 within the insert mounting portion 5 of the mold body 2, a pair of left and right clampers 10 are installed on the upper part of the fixed platen 1 on the open side of the insert mounting portion 5 (inside the insert mounting portion 5). (upper end surface of insert 4 inserted into)
It is mounted so that it can move forward and backward using a cylinder 11 facing the front.

Insert it into the nest mounting part 5 of. The insert 4 is inserted until it engages and slides with the guide rail 7 of the insert mounting part 5 with the protrusions 8 provided on both sides and hits the stopper 6, and by the engagement between the protrusions 8 and the guide rail 7. Positioning is performed in the left-right and front-back directions. After inserting the insert 4, the clamper 10 is advanced by the cylinder 11, and the upper end of the insert presses the insert 4 to hold it in pressure contact with the stopper 6. With this, nest 4
is vertically positioned, accurately positioned and held within the insert mounting portion 5 of the mold body 2, and together with the mold body 2 constitutes the surface molding portion of the injection molded product.
（考案の効果）
