摘要： PURPOSE:To uniformize pressure and to obtain a forming part of uniform nature by switching the control of a hydraulic cylinder to a pressure control from a speed control at the time when the hydraulic cylinder is moved by the amt. corresponding to a deviation value from the specified stroke position. CONSTITUTION:The die inner pressure P0 at the point S4 of the front of a speed-pressure switch is preset and the difference S in the inner pressure P of the point S4 and S5 switching from a speed control to pressure control is found in advance by an experiment, etc. The deviation value P of P0 and P and S at that time are then stored in a control device 28. In case of a material being overfilled, P1>P0 is attained by detecting the die inner pressure P1 at the point S4 of the front of the speed-pressure switching, P'=P0-P1 is found, the S' corresponding to this P' is found and switching is executed from speed control to pressure control at the position where a slide stroke becomes S5=S4+S'. The dispersion in the material filling state is thus detected by the die inner pressure and the filling completion time is corrected, so the switch of the speed-pressure control becomes at the material filled up time and the succeeding forming is uniformized.

摘要： PURPOSE:To perform the control of a compacting machine so as to obtain a good part by controlling the speed reduction control prior to switching to the pressure control from the speed control of the die of one part by the moving speed of a hydraulic cylinder to smoothly transfer to a pressure control, in the case of compacting a resin work inside the cavity of between a pair of dies. CONSTITUTION:One part of the die of a pair of dies 11, 12 is moved by a hydraulic cylinder 4 or 7 and a resin work is compacted inside the cavity 13 of between both dies 11, 12. In this case, the moving speed of the hydraulic cylinder 4 or 7 is controlled until the pressurizing of the work starts and the pressurizing force of the cylinder 4 or 7 is controlled after the pressurizing starts. The speed reduction control in the speed control prior to switching to the pressure control from the same speed is controlled by the speed V shown by an equation at the moving speed of the cylinder 4 or 7. The transfer to the pressure control is thus made possible smoothly, the pressure corresponding to a resin can be given and a good part can be obtd.

摘要： PURPOSE:To contrive improvements in accuracy of mesh at a cog part of a screw and workability, by a method wherein a half nut is moved by a necessary movement after comparing the necessary movement obtained by an arithmetic unit with movement of the half nut detected by a detecting member. CONSTITUTION:Driving of a jack 15 is begun and a necessary raising quantity of the jack 15 is calculated by an arithmetic unit 25 based on thicknesses of both molds, by a method wherein the thicknesses of the stationary and movable molds to be used are put in and a push button for mold thickness control is pushed. At the time when it is detected by a detecting member 24 that the number of revolutions of an input shaft of the jack 15 has arrived at a movement necessary for both screw cogs 13a, 13b to arrive at an appropriate mesh position, the jack 15 is stopped at once. Upon confirmation by a detecting member 18 that it is safe from a view point of mechanical actuation by detecting that both the screw cogs 13a, 13b have arrived at the appropriate mesh position after stop, a half nut 11 is moved forward to a closed position by driving a driving cylinder 14. With this construction, smooth mesh actuation of the screw cogs 13a, 13b is obtained without resistance.

摘要： PURPOSE:To permit the whole of the title device to be compacted and simplified by assembling principal mold clamping mechanisms on the side of a fixed platen, by a method wherein a tie rod is provided integrally with a moving platen and is penetrated slidably through the fixed platen while a mold clamping cylinder and a lock plate, integrated with the advancing and retreating ram of the mold clamping cylinder and equipped with a lock member, are provided on the fixed platen. CONSTITUTION:Upon closing a mold, a mold opening and closing cylinder 9 is operated to approach a moving platen 1 to a fixed platen 2. In this case, a tie rod 3 and a synchronizing lever 10 move freely through the fixed platen 2 and a lock plate 8, the collar 11 of the synchronizing lever 10 is engaged with the plate 8 and pushes the plate 8 while moving together therewith until the end face of the moving mold 13 of the moving platen 1 is contacted closely with the end face of the fixed mold 12 of the fixed platen 2. After a lock member 5 is moved to retain it to the engaging part 14 of the tie rod 3 under a condition that both of the molds are closed tightly, pressurizing fluid, such as pressure oil or the like is supplied to the head of a ram 6 for a mold clamping cylinder 7 in the fixed platen to generate a mold clamping force.
