Abstract
A moulding apparatus having a two-part mould movable between a receiving station at which thermoplastics synthetic material is extruded into the mould and a release station at which a moulded hollow body is removed from the mould. This hollow body is then supported by a blowing and calibrating member before being gripped by a two-part gripper which moves the body from the release station to a transfer station in synchronism with the mould movement. The gripper parts are mounted on arms or levers supporting and/or guiding the mould parts.
Claims16
Apparatus for the manufacture of blow-moulded, hollow bodies from thermoplastic synthetic material which transfers the hollow bodies during stages of manufacture between a receiving station which includes an extruder having an extrusion nozzle;
- a blow-mould and mould-release station having a holder;
- and a transfer station which transfers the hollow bodies away from the apparatus including:
- a hollow mould having at least two parts which receive thermoplastic material from the extrusion nozzle;
- a means connected to support each of the hollow mould parts;
- a gripper to temporarily hold the hollow bodies;
- a lever arm means to which the gripper is mounted and further to which the means supporting the hollow mould parts are attached such that the lever arm means operates to open and close the hollow mould parts and open and close the gripper;
- means connected to actuate the lever arm means;
- an automatically displaceable carriage;
- means connected to displace the carriage wherein;
- the lever arm means is connected to the carriage such that the means supporting the hollow mould parts is displaceable between the receiving station at which the hollow mould is closed and the mould release station at which the hollow mould is opened and the hollow bodies are removed from the hollow mould parts, and wherein the lever arm means is connected such that the gripper is displaceable between the mould release station at which the gripper closes to hold the hollow bodies and the transfer station at which the gripper opens to release the hollow body, wherein;
- during the displacement of the hollow mould parts from the receiving station to the mould-release station, the gripper is correspondingly moved from the mould-release station to the transfer station;
- and wherein the mould-release station holder supports the hollow bodies after the hollow mould parts are opened at the mould-release station.
Apparatus for the manufacture of blow-moulded, hollow bodies from thermoplastic synthetic material which transfers the hollow bodies during stages of manufacture between a receiving station which includes an extruder having an extrusion nozzle;
- a blow-mould and mould-release station having a holder;
- and a transfer station which transfers the hollow bodies away from the apparatus including:
- a hollow mould having at least two parts which receive thermoplastic material from the extrusion nozzle;
- a means connected to support each of the hollow mould parts;
- an automatically displaceable carriage;
- means connected to displace the carriage;
- means mounted to the carriage for supporting the means connected to support the mould parts and for guiding the mould parts for opening and closing movement relative to each other;
- parts forming a gripper;
- arm means to which the parts forming the gripper are mounted, said arm means being connected to said carriage for guiding the parts forming the gripper for opening and closing movement relative to each other;
- said means mounted to the carriage for supporting the mould parts and the means supporting the mould parts for movement between the receiving station and the mould release station, at which the hollow bodies are removed from the mould parts;
- said arm means mounted to the parts forming the gripper for movement between the mould release station at which the hollow bodies are received by the parts forming the gripper;
- and the transfer station at which the hollow bodies are received from the parts forming the gripper;
- such that during movement of the mould from the receiving station to the release station the parts forming the gripper are correspondingly moved from the release station to the transfer station;
- and
- wherein the mould-release station holder supports the hollow bodies after removal from the hollow mould parts at the mould-release station, and wherein;
- the arm means includes a separate arm member for each part forming the gripper, and wherein the apparatus further comprises:
- a separate guide means for each arm member, said arm members being connected to their respective guide means for guiding the parts forming the gripper for opening and closing movement relative to each other and during movement of the parts forming the gripper from the release station to the transfer station.
