PURPOSE:To simplify and miniaturize the structure of device on a base plate as well as reduce the cost of the molding machine by using a system in which the vertical movement of core, rod, and mold-releasing part is performed by means of a common elevator. CONSTITUTION:On a base plate, a working plate 9 intended for a temperature regulation portion B, a stretching blow molding portion C, and a mold-releasing portion D is provided in a vertically movable manner by means of a guide lever 10 and an elevator 12 attached to the base plate 2. A blow core 18 having a stretching rod 17 piercingly provided and a stretching rod expander 19 are provided in a place corresponding to the stretching blow molding portion of the working plate 9. Also, on places corresponding to the temperature regulation portion B and the mold-releasing portion D, a temperature regulation core 16, a mold releasing part 20, and a core 21 are provided in such a way as to enable the vertical movement of the core and molding releasing part to be permitted concurrently by the vertical movement of the working plate 9. The portion A is an injection molding portion. |
