Improved automatic multicolour rubber moulding machine.

摘要

An automatic multicolour rubber moulding machine comprising a feed unit (2) having a plurality of tanks (21) for rubber material of different colours, a heating and pressing unit (1) having upper and lower electric heaters (11), and a mould unit (4) consisting of one or more distribution boards (5) mounted on the bottom of the rubber tanks (21) and including a plurality of gates (51), paths (52) and ports (53). A female mould (6) is mounted for insertion into the feed unit (2) and the heating and pressing unit (1). A male mould (7) is attached to a mould opener (3) or is mounted under the upper heater in the heating and pressing unit (1) and is constructed in such a way that the female mould (6) can enter the feed unit (2) for the rubber material of different colours to flow from the tanks through the gates (51), paths (52) and ports (53) of the distribution board (5) into the cavities in the female mould (6), be withdrawn for the mould opener (3) to put on the male mould (7), re-enter the heating and pressing unit (1) for heating and vulcanizing and be withdrawn again for the mould opener (3) to open the moulds for removal of the final products so that the multicolour products are made in an integrated operation.
