System for feeding molten resin and method of feeding molten resin

To efficiently feed a molten resin to the resin holders. An intermittently feeding device works to intermittently feed a transfer unit equipped with resin holders, and has a cam supported by a motor via a support. The cam is rotated by the motor. A cam follower of a moving block meshes with the screw of the cam, and the moving block moves along a support rail accompanying the turn of the cam. The motor rotates at a constant speed, and the transfer unit 3 is fed intermittently depending on the shapes of the cam and of the cam follower.

An apparatus includes one or more die groups which are movable independently of one another, each including a female part having a matrix cavity and a male part destined to penetrate into the cavity such as to define a forming chamber of the product, the cavity configured to contain a batch of material. The apparatus further includes a heating station having a heater to bring the plastic material to the fluid state, and a die group cooling station downstream of the heating station. The die groups are free to be cyclically inserted in the heating station and subsequently transferred to the cooling station. A thrust group is associated to a respective die group and is configured to provide a thrust for penetrating the male part into the cavity during the stage of forming the product, the thrust group being integral with the respective die-group in displacements during the operations performed.
