A bottle blowing machine is provided in the invention. The bottle blowing machine comprises a machine frame, a mould opening and closing assembly, an elevating assembly, a bottom mould locking assembly and a driving assembly. The mould opening and closing assembly comprises a bottom mould, a fixed mould plate and a moving mould plate. The elevating assembly comprises a protrusion, an elevating rod and a sliding block. A guiding groove is opened on the protrusion, and the sliding block is slidably disposed in the guiding groove. The bottom mould is fixed on the upper end of the elevating rod. The bottom mould locking assembly comprises a rotation member, a swing member and a sliding block slidably disposed on the machine frame. The driving assembly comprises a rotation shaft and a power source for driving the rotation of the rotation shaft. The moving mould plate, the protrusion and the rotation member are simultaneously fixedly connected with the rotation shaft. When the rotation shaft rotates, the fixed mould plate and the moving mould plate close the mould, the elevating rod drives the bottom mould to rise, and the sliding block slides into between the machine frame and a bottom mould. In the bottle blowing machine of the invention, three assemblies are simultaneously driven only by one rotation shaft to move, and the steps of mould closing, elevating and locking are operated simultaneously. Thus, the bottle blowing machine of the invention is simple in structure and convenient in operation, thereby improving the efficiency of the process of bottle blowing.

An object of the invention is to provide a blow mold unit and a blow molding machine which can stabilize a bottom mold clamping motion to thereby mitigate loads to be applied to a bottom mold driving mechanism and molds. A blow mold unit (10) has a construction in which, when clamping first and second blow cavity split molds (12, 14) which are fixed to first and second fixing plates (40, 50) and bottom molds (100) which are fixed to a bottom mold fixing plate (10), pressure receiving members (60) fixed to the first and second fixing plates (40, 50) are brought into engagement with the bottom plate fixing plate (110). Guide plates (120) are fixed to the bottom mold fixing plate (110), and guided members (70) capable of being brought into abutment with the guide plates (120) are supported by first and second pressure receiving plates (20, 30). The bottom mold fixing plate (110) includes a first connecting portion (116) to be connected to a bottom mold opening/closing unit (210) which is to be driven by a clamping mechanism provided to a blow molding machine, and a second connecting portion (116) to be connected to a moving and biasing member (250) which is provided to the blow molding machine (200) and moves and biases the bottom molds, which are in the closed position, in a direction in which the bottom molds are closed.

摘要:
The method and the device are used to blow mould containers. A parison is transformed into the container after thermal conditioning within a blow mould of a blow moulding machine by the action of blowing pressure. In order to adjust to a contour of the container to be produced, prior to the moulding of the container, at least a part of a first blow mould is first removed from the blow station and replaced by at least a part of a second blow mould. Before the part of the first blow mould is removed, a locking device which fixes this part in the blow station is released and after the insertion of the part of the second blow mould said locking device is again positioned for fixing the part of the second blow mould. Each locking device is coupled to an operating element.
