不具合を免れなかつた。 Moreover, in order to perform insert molding with a horizontal injection molding machine, the insert material to be inserted into the injection cavity must be held in the mold in advance, otherwise it may fall out. For insert molding of small parts that are difficult to hold or precision parts that require precision insert positioning, a vertical injection molding machine that opens and closes the mold upward and downward is preferable, and this type of vertical injection molding machine For example, a molding machine as described in Japanese Patent Publication No. 54-15578 is already known. However, in this conventionally known vertical injection molding machine, a spring guide tube is installed on the circumferential surface of the tie bar between the rotating disk rotatably placed on the upper surface of the fixed platen and the mold clamping plate.
Since a rotating disk clearance adjustment device consisting of a spring, a spring receiver, etc. is installed, the rotating disk can be mounted in a narrow frame that supports and fixes the fixed platen together with a mold clamping device, a rotating disk drive device, a dowel pin protruding cylinder, etc. A clearance adjustment device must be provided, which makes the structure complicated and difficult to maintain and manage.There is also a limited selection of mold clamping mechanisms (toggle type mold clamping mechanisms cannot be adopted), which limits the degree of freedom in design. This problem was inevitable.

も増す等の効果を有する。 As described above, according to the present invention, the interval adjustment device attached to the fixed platen or the rotating disk maintains the fixed platen and the rotating disk at a constant distance when the mold is not clamped, and the rotating disk or the fixed platen Since it is in only point or line contact with the resiliently supported ball or cylindrical roller, it is possible to smoothly rotate the rotating disk. Therefore, when performing movable insert molding with this molding machine, the rotating disk will vibrate or rock even when the lower mold into which the insert material has been previously inserted outside the mold clamping position is rotated and inserted into the mold clamping position. Since the insert material does not shift or fall, highly accurate insert molding is possible. In addition, unlike conventional equipment, there is no need to install a mold clamping device, a rotating disk driving device, etc., as well as a gap adjustment device between the fixed platen and the rotating disk in a narrow frame, making maintenance and management of the molding machine easier, and the design This has the effect of increasing the degree of freedom above.
