I like blow mold industry!

A blow moulding machine having a pair of stationary moulds and a single vertically and pivotally movable extruder above the moulds for supplying extrudate alternately to the respective moulds, movements of the extruder being controlled by a guide track arrangement and a piston and cylinder assembly, and each mould comprising a moulding cavity and a waste removal and ejecting cavity transfer means being provided for transferring a blown product from the moulding cavity to the waste removal and ejecting cavity.

Blow Molding Machine for producing hollow bodies of thermoplastic material, by the blow-extrusion process, includes blow mold halves arranged inside a chase between form plates of the chase. Between a receiving position, aligned with an extrusion nozzle, and a blowing position offset laterally relative to the receiving position. Vertical guides on the form plates engage guide plates on the blow mold halves for vertical displacement of the blow mold halves relative to the chase to lower the blow mold halves when the chase is moved to the blowing position.

Blow Molding Machines halve and operate automatically and a rack and gear type lifting mechanism acts between the form plates. Responsive to movement of the chase to the blowing position, to lower the blow mold halves. Rollers may be interposed between the guide plates and the form plates to facilitate relative movement. The blow mold halves may be closed by the usual cylinder and piston arrangements. But preferably are closed by a toggle mechanism which moves the two blow Molding halves toward each other. The blow mold halves being supported for such movement on guide rods.
