  • FIG. 1 illustrates the breech mechanism of the invention as applied to a molding machine of the type described in US. Pat. No. 3,590,418, issued July 6, 1971 and assigned to the assignee of the present invention. It will be understood, however, that the invention has been shown and described as applied to such machine only for the purposes of illustration; and the invention is equally applicable to other forms of molding machines of the beforedescribed general type.
  • the molding machine illustrated in FIG. 1 comprises a generally vertical first platen 10 mounted upon the upper surface of a ground supported base or base pad 12 which also carries the injection unit of the molding machine, such injection unit being designated generally as 14.
  • the injection unit 14 may be of any suitable conventional construction and, as shown, includes a receiving hopper 16, an injection ram device 18, a plasticizing and feed device 20, and a discharge nozzle 22 which projects through an opening through the first platen 10.
  • a generally vertical second platen 24, oppositely disposed to the first platen 10, is suspended by a supportingshoe 26 from a generally horizontal guide track 28 which is, in turn, ground mounted by a plurality of supporting posts 30.
  • the platens 10,24 carry the usual mating mold sections or halves 32,34; and the 2 second platen 24 is, during the operation of the machine, driven by a cylinder-and-piston motor 36 towards-and-away from the firstplaten 10 between a mold closed-position (shown'in solid lines in FIG. 1)
  • the second platen 24 carries four tie rods 38 which project horizontally from the second platen 24 towards the first platen l0 and, with the second platen 24 in its mold closed position, slidably extend through openings in the first platen 10 into individual breech mechanisms, each designated generally as 40, associated with the latter.
  • the tie rods 38 as illustrated, extend through the second platen 24 into individual retraction tubes 42 mounted on the second platen 24 and are in the manner described in US. Pat. No. 3,465,387, issued Sept. 9, 1969 and assigned to the assignee of the present invention, adjustable by drive means (not shown) on the second platen 24 to vary the portions of their lengths projecting from the second platen 24 towards the first platen 10.
  • Such portions of the lengths of the tie rods 38 are advantageously maintained sufficiently short to permit the tie rods 38 to be entirely removed from their openings in the first platen 10 during the movement of the second platen 24 away from the latter thereby facilitating the a molding machine of this general type, if desired, can
  • tie rods 38 alternatively could be mounted to the first platen in which event the breech mechanisms 40 would be associated with the second platen 24 for movement therewith.
  • the breech mechanisms 40 are all of identical construction and arrangement and hence, although only one thereof has been illustrated in FIGS. 2 through 5 and hereinafter specifically described, it will be'understood that all of the other breech mechanisms 40 are the same as that so illustrated and described.
  • the breech mechanisms 40 each include a breech housing or casing 44 containing aligned, upper and lower breech blocks 46,48, respectively, which are vertically movable towards-and-away from one another and provided with semi-circular recesses 50,52 cooperative to grip the end 54 of a tie rod 38 between-the breech blocks 46,48.
  • the semi-circular recesses 50,52 and the tie rod end 54, as illustrated, are preferably provided with cooperative grooves 56,58, respectively, facilitating the gripping of the rod end 54 by the breech blocks 46,48.
  • the breech blocks 46,48 are mounted in a manner permitting their'longitudinal and lateral movement relative toa therebetween tie rod end 54, thus accommodating tie rod stretch and enabling the breech blocks 46,48 to be self-aligning with the tie rod end 54. More particularly, the breech blocks 46,48 are slidably mounted for their beforedescribed vertical movement on a pair of vertical slide rods 60 which at opposite ends areaffixed to carriage frames or carriages 62.
  • the carriages 62 are each slidably mounted on a pair of horizontal slide rods 64, extend- :ing parallel to the tie rod 38, by separate supporting or which engages a corresponding flat surface 74 on a carriage 62 to key the latter to the bearing shoe 66.
  • the carriages 62 are resultantly slidable both longitudinally along and laterally of the horizontal tie rods 62; and the breech blocks 46,48, being carried by the carriages 62 through the vertical slide rods 60, are enabled to both move longitudinally of the tie rod 38 to accommodate tie rod expansion and horizontally laterally of the tie rod 38 to readily self-align therewith.
  • the breech blocks 46,48 are vertically driven towards-and-away from each other by individual cylinder-and-piston actuators 76 carried by the carriages 62 whereby the actuators 76 for the breech blocks 46,48 are on opposite sides of the latter.
  • the actuators 76 are of identical construction and size and each include a cylinder 78 fixedly mounted on a carriage 62 and a piston 80 which is slidably in the cylinder 78 and connected to a breech block 46 or 48 by an extension rod 82. Both of the actuators 76 of each breech mechanism 40 are connected to a common source of pressure fluid whereby the fluid at such common pressure is supplied to their cylinders 78 to drive the breech blocks 46,48 towards one another.
  • the pressure fluid is supplied through a singly supply conduit 84, communicating with a source (not shown) of the pressure fluid, and branch conduits 86,88 connecting the head ends of the cylinders 78 of both actuators 76 to such supply conduit 84.
  • a source not shown
  • branch conduits 86,88 connecting the head ends of the cylinders 78 of both actuators 76 to such supply conduit 84.
  • the rod ends of the cylinders 78 of the actuators 76 are provided with' individual fluid connections which communicate with the source.(not shown) of the pressure fluid in a conventional manner; and suitable conventional valving means (not shown) interconnect the fluid connections 90 and the supply conduit 84 whereby, in the conventional manner, pressure fluid may be selectively supplied through each thereof to one end of each of the cylinders 76 while fluid is ex-' hausted through the other thereof from the other end of each cylinder 76.
  • Each breech mechanism is provided with the usual load cell 92 which, after the tie rod ends 54 have been gripped by the breech blocks 46,48 of all of the breech mechanisms 40, is the usual manner fluid actuated to exert clamping force on the second platen 24 through the respective adjacent breech blocks 46,48 and their gripped tie rod 38.
  • each breech mechanism 40 is provided with a cylinder 96, aligned with its respective tie rod 38, which slidably contains both a cushioning piston 98 and a theresurrounding break-away or push-back piston 100.
  • the cushioning piston 98 is fluid biased to engage the tie rod end 54 during axial movement of the tie rod 38 into the breech mechanism 40, thereby cushioning or absorbing the shock of such tie rod movement.
  • the push-back piston 100 is fluid actuated to, in cooperation with the cushioning piston 98, assist in initiating axial movement of the tie rod 38 out of the breech mechanism 40 after opening of the breech blocks 46,48 by their movement from one another.
  • Load cells and cushioning and push-back cylinder and-piston arrangements of this general type are, of course, per se well known in the art. For example, the beforementioned U.S. Pat. No. 3,465,387 described generally similar apparatus for these purposes.
  • the tie rod ends 54 are moved intermediate the open breech blocks 46,48 of their respective breech mechanisms 40, while low pressure fluid in the cylinders 96 causes the cushioning cylinders 98 to cushion the tie rod movement.
  • Each tie rod end 54 during its said movement trips the usual limit switch 102 whereupon, afterall such limit switches 102 have been so tripped indicating that the tie rod ends 54 are all in position for gripping by their respective breech blocks 46,48, pressure fluid is caused to flow from the source (not shown) through the supply conduits 84 and branch conduits 86,88 to the head ends of the cylinders 78.
  • the limit switch 104 is resultantly tripped, thereby causing pressure fluid to be supplied through the passage 106 to the load cell 92.
  • This pressure fluid in the conventional manner causes the load cell 92 to apply clamping force on the second platen 24 through the breech blocks 46,48 and the tie rods 38; and during the application of such clamping force, plasticized material is injected between the mold halves 32,34.
  • the passage 106 is connected to exhaust, thereby releasing the clamping pressure; and pressure fluid is supplied to the rod ends of the actuator cylinders 78, while fluid is exhausted from the head ends thereof, thereby driving the breech blocks 46,48 one from the other to their open positions.
  • the limit switch 108 is tripped causing the pistons 98,100 to be fluid driven to initiate movement of the tie rods 38 out of the breech mechanisms 40 and the second platen 24 is driven away from the first platen preparatory to commencing another operating cycle of the machine.
