Abstract
A method of controlling a blow molding machine from a completion of production of one product to a start of production of a next product comprises controlling a temperature of a resin within the blow molding machine, controlling an operation of devices from the completion of production of the one product to the start of production of the next product, controlling a sequent transport of some of the devices in predetermined positions, and controlling a change of the resin in accordance with a supply stop thereof and a data on the next product.
Claims6
A calibrating unit for use in a blow molding machine, comprising:
- a first block;
- a second block slidably engaged with said first block, said second block having a plurality of blow pins;
- and
- a passage means for allowing a fluid communication between said plurality of blow pins,
- whereby the height of said plurality of blow pins is automatically adjusted in accordance with a mold by a fluid within said passage means.
A calibrating unit for use in a blow molding machine, comprising:
- a first block formed with a dovetail groove, said dovetail groove being defined by locking blocks which are moveable;
- a second block slidably engaged with said dovetail groove;
- and,
- a third block connected to said second block, said third block having a plurality of blow pins and being formed with a plurality of cylinder chambers for receiving said plurality of blow pins to which nozzle bodies are connected, each nozzle body having an upper portion with a manifold connected to a cylinder which is filled with a fluid so that said each nozzle body is axially movable, said third block being formed with passages which correspond to said manifold and having openings in a side thereof facing said second block,
- said second block being formed with a passage which communicates with said cylinder, and
- said first block being formed with passages having openings which face said openings of said passages of said third block.
A calibrating unit for use in a blow molding machine, comprising:
- a first block;
- a second block slidably engaged with said first block, said second block having a plurality of blow pins and a plurality of chambers associated with said plurality of blow pins;
- and
- a communication passage arranged to allow fluid communication between said plurality of chambers, whereby the height of said plurality of blow pins is automatically adjusted by a fluid within said communication passage.
