Abstract

Provided is a blow molding machine including an injection molding unit and a blow molding unit, wherein the injection molding unit includes a preform mold and an injection device configured to supply resin to the preform mold, wherein the injection device is fixed to a support plate, and wherein the support plate includes a position adjustment mechanism capable of adjusting a position of the injection device in an upper and lower direction with respect to the preform mold.

First claim

What is claimed is:

1. A blow molding machine comprising:
an injection molding unit configured to manufacture a bottomed preform made of resin; and
a blow molding unit configured to manufacture a container by blow-molding the preform manufactured by the injection molding unit,
wherein the injection molding unit includes:
a mold configured to manufacture the preform; and
an injection device configured to supply resin which is a raw material to the mold,

wherein the injection device is fixed to a support plate,
wherein the support plate includes a position adjustment mechanism capable of adjusting a position of the injection device in an upper and lower direction with respect to the mold, and
wherein the position adjustment mechanism includes:
a machine table;
a lifting and lowering mechanism configured to lift and lower the support plate with respect to the machine table;
a locking block fixed to the support plate and having locking recesses formed in a plurality of stages in the upper and lower direction and extending in a horizontal direction; and
a locking plate provided to the machine table and configured to be locked into and unlocked from any one of the locking recesses by being slid in a direction approaching and separating from the locking block.

2. The blow molding machine according to claim 1 , further comprising:
a plurality of processing units including at least the injection molding unit and the blow molding unit, the plurality of processing units being arranged at a predetermined angular interval in the horizontal direction on the machine table;
a plurality of transfer plates arranged at a predetermined angular interval in the horizontal direction above the machine table;
a neck mold provided to the transfer plate and capable of gripping a preform molded by the injection molding unit; and
a transport mechanism configured to lift and lower the transfer plates at the processing units and intermittently rotate the transfer plates at a predetermined angular interval in the horizontal direction,
wherein the preform molded by the injection molding unit is pulled up from a cavity mold configuring the mold according to the lifting of the transfer plate by the transport mechanism and is sequentially transported to the processing units according to the intermittent rotation of the transfer plate at the predetermined angular interval in the horizontal direction by the transport mechanism.
