A jarring moulding machine having a table and impact receiving arrangement between the table and an anvil, which arrangement includes an annular impact member recessed into a surface of the anvil, and an impact insert of greater resilience than the impact member seated in an annular recess of step form at the inner periphery of the annular impact member. The top surface of the impact member projects slightly beyond of the anvil surface and the top surface of the impact insert projects slightly beyond of the top surface of the surrounding impact member so that the insert receives the impact before the impact member. The seating recess for the insert is undercut at the junction of its walls so as to leave a small clearance therebetween. The impact member may be of a polyethylene synthetic plastics material and the insert may be of rubbery polyurethane.
Jarring moulding machine having a table and an anvil member disposed for relative movement with respect to one another, an impact receiving means disposed between said table and a supporting surface of said anvil member, said impact receiving means comprising at least one impact member arranged in said supporting surface, for impact contact with said table resulting from this relative movement of the table and anvil member, and at least one impact insert which is resilient relative to the impact member and arranged in said impact member so that the impact insert receives impact contact with the table before the impact member.
Jarring moulding machine comprising a table member and an anvil member, the table member and anvil member being movable with respect to one another, the anvil member being provided with a supporting surface and an impact member being disposed between the table member and the supporting surface for impact contact with the table member resulting from the movement of the table member and the anvil member with respect to one another and at least one impact insert means arranged in the impact member for impact contact with the table member prior to the impact contact by the impact member with the table member for reducing noise of the impact, the impact insert means being resilient relative to the impact member.
