を目的としている。In a molding device with such a structure, the insert and the insert carrier are rigidly connected, so when the molding device needs to be heated, such as when molding a shell sand core, the main mold and Due to the difference in thermal expansion between the insert and the insert carrier, the axial center of the cylindrical portion of the insert and the axial center of the engagement hole of the main mold may become misaligned, and the mold connection between the insert and the main mold may not be achieved properly. be. In view of the above-mentioned problems in conventional mold devices equipped with inserts, the present invention has been developed to prevent mold coupling between the insert and the main mold even if a difference in thermal expansion occurs between the main mold and the insert supporter. The purpose of the present invention is to provide an improved molding device that allows for better performance.

れている。The clearance between the flange portion 10 and the floating bushing element 13 is set to a dimension corresponding to the thermal expansion difference between the main mold and the upper insert carrier 8 under normal use. , and the clearance between the accommodation hole 9 and the straight cylindrical portion 10 is also equal to this dimension.
or even larger. The upper insert carrier 8 is connected to a mold drive element 14 and is thereby driven in the vertical direction in the figure, so that the tapered cylindrical portion 7 of the upper insert 6
into and out of the tapered engagement hole 4 of the main mold. Further, the upper insert carrier 8 is adapted to be molded with its lower bottom surface 15 in contact with the upper surface 16' of the main mold, so that the floating bushing element 1
3 is housed in a recess 17 formed in the upper insert carrier 8 so as not to protrude below the lower bottom surface 15, and the head of the bolt 12 is inserted into a hole 18 formed in the main mold.
It's designed to go inside. Said upper insert loss support body 8
A core sand blowing port of a core molding machine (not shown in the figure) is engaged with the upper surface, and the core sand is poured into the mold chamber 3 from the upper insert 6.
It is supposed to be blown inside. Therefore, a insert cover 19 is attached to the upper end of the upper insert 6 to prevent core sand from entering the accommodation hole 9. This insert cover 19 is configured so that it overlaps the upper insert carrier 8 even when the upper insert 6 is displaced to the maximum extent in the radial direction with respect to the upper insert abutment 8, and The upper nesting carrier 81 is accommodated in a recess 20 formed so as not to protrude above the upper surface of the carrier 8. 21 is the lower insert (
This lower mold insert 21 is formed in a tapered cylindrical portion 22 that engages with the tapered engagement hole 5 so as to be able to freely enter and exit, and a lower mold insert carrier (lower mold main body) 23. A straight cylindrical portion 25 that plays in the accommodation hole 24, and a flange portion 2 formed between the tapered cylindrical portion 22 and the straight cylindrical portion 25.
6, and like the upper insert 6, the flange portion 26 is attached to the lower insert carrier 23 by bolts 27.
By engaging with the flanged floating bushing element 28 fixed to the flange with a predetermined clearance in both the vertical direction and the axial direction, the bushing element can be moved particularly in the radial direction with respect to the lower insert retaining body 23. has been done. In this case, the flange portion 26 and the floating bushing element 28
Similar to that of the upper insert 6, the clearance between the upper insert 6 and the lower insert carrier 23 is sized to correspond to the thermal expansion difference between the main mold and the lower insert carrier 23 under normal use. Hole 2
4 and the straight cylindrical portion 25 is also dimensioned to be equal to or greater than this dimension. The tapered cylindrical portion 22 of the lower insert 21 is moved in and out of the tapered engagement hole 5 of the main mold by being driven in the direction, and the upper surface 29 is brought into contact with the lower bottom surface 30 of the main mold. In this case as well, the floating bush element 28 is housed in a recess 31 formed in the lower insert carrier 23 so as not to protrude above the upper surface 29, and the bolt 27 The head of the mold is engaged with a groove 32 formed in the main mold to prevent core sand from accumulating around it. 33 is a lower extrusion pin;
The lower push-out pin 33 is fixed to the lower push-out plate 34 so as to be movable in radial directions by a holding member 35 so that it can be inserted into the hole of the lower insert 21 even if the lower insert 21 moves in the radial direction. ing.

、主型に係合するようになる。Moreover, in this case, the lower extrusion pin 33 is inserted into the lower insert 2.
The ejector pin entrance side of the hole is widened as shown in the figure so that it can be inserted smoothly into the hole at all times. As described above, the upper and lower inserts 6 and 21 are supported by the upper and lower insert carriers 8 and 23, respectively, so as to be movable within a predetermined range in all directions of the diameter of the tapered cylindrical portions 7 and 22, Moreover, since the tapered cylindrical portions 7 and 22 of each insert are adapted to engage with the tapered engagement holes 4 and 5 of the main mold, respectively, the thermal tension between the main mold and the insert carrier is reduced. Even if the axes of the tapered cylindrical portion of each insert and the tapered engagement hole of the main mold are misaligned due to reasons such as this, the insert will be guided into engagement between the tapered cylindrical portion and the tapered engagement hole when the mold is clamped. It is aligned and engaged with the main mold.
