Injection molding device

A device for injection moulding a plastic object, comprising:

• a frame,
• a first platen and a second platen, which are respectively designed for fixing thereto a first mould half and a second mould half of an injection mould,
• displacement means belonging to at least one of said first and said second platens, enabling said first and said second platens to be displaced towards one another in a closure direction from an open position into a closed position, in which said first mould half and said second mould half bear against one another on a parting plane,
• said mould having an insertion opening for inserting a mould core from the outside, said insertion opening being situated at said parting plane,
• closure force means for creating a closure force, by means of which said first mould half and said second mould half, in the closed position of said first and said second platens, can be held pressed together at least while plastics material is being injected into said mould, and
• injecting means for injecting plastics material into said mould, wherein said device comprises a core pressure means for exerting pressure on said mould core, said core pressure means being designed to press said mould core, which has been inserted into said mould, with a certain force into said mould, and wherein said core pressure means for exerting pressure on said mould core can be actuated separately, enabling said pressure on said mould core to be adjusted independently of said closure force.

A device for injection moulding a plastic pallet, comprising:

• a frame,
• a first platen and a second platen, which are respectively designed for fixing thereto a first mould half and a second mould half of an injection mould for injection moulding a pallet,
• displacement means belonging to at least one of said first and said second platens, enabling said first and said second platens to be displaced towards one another in a closure direction from an open position into a closed position, in which said first mould half and said second mould half bear against one another on a parting plane,
• said mould having an insertion opening for inserting a mould core from the outside, said insertion opening being situated at said parting plane,
• closure force means for creating a closure force, by means of which said first mould half and said second mould half, in said closed position of said first and said second platens, can be held pressed together at least while plastics material is being injected into said mould, and
• injecting means for injecting plastics material into said mould, wherein said device comprises a core pressure means for exerting pressure on said mould core, said core pressure means being designed to press said mould core, which has been inserted into said mould, with a certain force into said mould, and wherein said core pressure means can be actuated separately, enabling said pressure on said mould core to be adjusted independently of said closure force.
