Device for moulding plastic parts

A device for moulding plastic parts, comprising a first element (100) with at least one cavity (101) configured to receive and shape a portion or sheet of plastic material, and at least one second element (200) configured to cover the at least one cavity (101) of the first element (100) and assist in the shaping of the portion or sheet of plastic material, wherein the device is configured to shape the portion or sheet of plastic material by suction and/or blowing a gaseous fluid, wherein the first element (100) comprises:

• a coolant inlet (108) configured for connection of an external coolant pumping system;
• at least one coolant pipe (107), formed in the first element (100), connected to the coolant inlet (108), wherein the at least one coolant pipe (107) is configured to allow the flow of coolant along said at least one coolant pipe (107),
• a plurality of spray orifices (110) configured to allow the outlet of the coolant from the at least one coolant pipe (107) and its spraying against a lower face of the at least one cavity (101), and
• at least one drain (109) configured to allow the discharge of the coolant from the at least one coolant pipe (107),
• wherein the first element (100) comprises at least one cooling gallery (106) formed in the first element (100) configured to collect the coolant sprayed from the spray orifices (110) and direct the coolant towards the at least one drain (109), wherein the first element (100) comprises:
• a first base (100a) which in turn comprises the at least one cavity (101), the at least one cavity (101) comprising suction orifices (102);
• a second base (100b) located on the opposite side to the at least one cavity (101) of the first base (100a), and;
• an intermediate panel (100c), arranged between the first base (100a) and the second base (100b);
• wherein the intermediate panel (100c) comprises the coolant inlet (108), the at least one drain (109), the at least one coolant pipe (107) and the at least one cooling gallery (106),
• wherein the first element (100) comprises a suction nozzle (105) and the at least one cavity (101) comprises a plurality of suction orifices (102) connected to the suction nozzle (105), wherein the suction nozzle (105) is configured for the connection of an external suction system, and
• wherein the suction orifices (102) of the at least one cavity (101) pass through the first base (100a) and are connected to the suction nozzle (105) through suction ducts (103) arranged on the intermediate panel (100c), wherein each of the suction ducts (103) connects to each of the suction orifices (102) with a suction chamber (104) existing in a space between the intermediate panel (100c) and the second base (100b), and wherein the suction nozzle (105) is arranged in the second base (100b) and is configured to connect the suction chamber (104) with the external suction system.
