Abstract

Single closing ram controls the moving parts of 2 moulds, opening one when the other closes. The jack is actuated by a known low pressure distributor connected to a known control fluid circulation. Two high pressure injection distributors control respectively 2 injection rams each of which moves a piston which cooperates with an injection pot. The movement of each piston is controlled, for each high pressure distributor, as a function of the injection time required for the the corresponding mould. The closing ram is controlled as a function of the cooling times for the moulds.
