Title: Plastics injection-moulding machine utilizing premixed billets
IPC: B29C31/02
Filed: 1970-06-03
Abstract: 1317599 Injection moulding machines NEW BRITAIN MACHINE CO 3 June 1970 [22 Oct 1969] 26774/70 Heading B5A [Also in Division B8] In an injection moulding machine of the type in which an axially reciprocable screw accumulates a charge of plasticized working material during a rearward rotary movement and then forces the charge into the injection mould during a subsequent forward non-rotary movement, the material is fed through a feeding means to the screw in the form of a succession of billets. Sensing means are provided to sense a predetermined minimum amount of billet material left and when the crew has reached its rearward position, to supply a new billet to the feeding means. In the described embodiment, a plasticizing screw 16 is reciprocated by a ram 28 and rotated by a motor 18, the forwardmost and rearmost limits of travel being defined by switches 44 and 50. The screw serves to plasticize a succession of cylindrical billets fed to the screw at a point intermediate its length through a housing 56 and to inject the plasticized material into a clamped mould 26. Each billet is pushed against the screw by a reciprocable plunger 60 and is fed to the housing from a magazine 54 via a guide 85. In operation, a lower position of the plunger, which position corresponds to a predetermined remaining length of billet and thus to a predetermined minimum amount of billet, is defined by a switch 66 which is engaged by a lug 64 carried by the plunger rod. Upon contact of the switch 66 with the lug and upon contact of switch 50 by the ram, the plunger is retracted, this movement serving to release a billet from the magazine into the housing 56 where it rests upon the partially used billet already in the housing. Further upward movement of the plunger rod causes the lug to engage a switch 88 which reverses its motion causing it to move down and engage the fresh billet and press both billets against the screw. The screw is re-actuated and commences its next forward injectionmovement. Should a billet fail to be fed to the housing, means are provided to halt operation only when the screw is stationary and the mould open.
