Abstract: A mold release lubricant application equipment 4 comprises application portions 30A,30B for applying a mold release lubricant to glass bottle forming molds 10, 18, and an application control portion 31 for operating the application portions 30A,30B. Molds 10,18 are arranged independently along a predetermined arrangement direction A1. A plurality of sections 5 comprising molds 10, 18 are formed along the arrangement direction A1. The application portions 30A, 30B comprise lubricant application parts 38A, 38B for applying the mold release lubricant, a transport mechanisms 33A, 33B for moving the lubricant application parts 38A,38B among the plurality of the sections along the arrangement direction A1, and sensors 42A, 42B. The application control portion 31 detects abnormalities with the sensors 42A, 42B on a plurality of sections 5.

Abstract: This invention eliminates the need for a manual work of applying a mold release lubricant to blow molds and bottom molds by workers and reduces a burden on workers involved in the mold release lubricant application work while also increasing the safety of workers during mold release lubricant application, reducing downtime associated with the mold release lubricant application work, reducing changes in the mold release lubricant application locations and variations in amount of application for the blow molds, and, furthermore, contributing to a glass bottle quality stabilization. The application equipment (40) for applying the mold release lubricant is structured to apply the mold release lubricant to at least either a part of blow mold forming surfaces (31f) provided on the blow molds (31), or the entire surface of bottom mold forming surfaces (32f) provided on the bottom molds (32) located in the lower part of a finish molds (31), or both.

Abstract: A parison forming apparatus comprising: a molding die into which a gob is introduced; a plunger 1 entering into the inside of the molding die for forming a parison from the gob together with the molding die; a cylinder that allows the plunger 1 to reciprocally move with respect to the molding die; and a cooling device for introducing cooling air into the inside of the plunger 1 to cool the plunger 1. The base end portion of the plunger 1 is connected to and held by the head of a piston rod 12 of the cylinder via a plunger holding mechanism 2. The plunger holding mechanism 2 has an adapter 21 connected to the head of the piston rod 12, and the adapter 21 is integrally provided with a tubular part 33 having a fitting hole 32 adapted to the cylindrical outer shape of the base end portion of the plunger 1.
