摘要： PURPOSE:To increase production cycle by enabling the rapid rotation and accurate stop of a rotary table in a vertical rotary type injection molding machine. CONSTITUTION:A rotary table 24 is rotationally driven in a rotary drive part using a servo motor 36 as a drive source. At this time, a control unit 50 receives a signal from an encoder 48 to execute an acceleration step accelerating the rotary table 24 up to the max. speed C3 in an acceleration stage Al, an equal speed stage C1, an acceleration stage A2, an equal speed stage C2 and an acceleration stage A3 according to an automatically preset acceleration and deceleration model. Next, the control unit 50 executes a deceleration step stopping the rotary table 24 through a deceleration stage R1, an equal speed stage C4, a deceleration stage R2, an equal speed stage C5 and a deceleration stage R3. Since the rotary table 24 is rotationally driven through multistage acceleration and multistage deceleration, the rotary table 24 is rapidly accelerated to be rotated and accurately stopped.

摘要： PURPOSE:To easily perform the mounting work of a metal mold in a short period of time by attaching a plurality of sets of metal molds to a common metal mold attaching board, and detachably attaching the plurality of sets of metal molds to a rotary board and a stationary board opposed to the rotary board or a movable board through the attaching board. CONSTITUTION:Upper molds 26 and lower molds 28 of a plurality of sets of metal molds are attached to common metal mold attaching boards 30, 32. The plurality of sets of the molds 26, 28 are detachably attached to a rotary board 20 and a lower surface plate 10 opposed to the board 20 through the boards 30, 32. Then, the positional relation between the metal molds (the upper and lower molds 26, 28) can be regulated outside a molding machine, and the metal mold attaching work can be extremely easily performed. After the molds 26, 28 are attached to the boards 30, 32 at predetermined positions, the molds can be replaced with high positioning accuracy merely by attaching or detaching the boards 30, 32 to the board 20 and the plate 10.

摘要： PURPOSE:To enable a single cylinder to perform the respective functions or the sealing of vent, cutting of gate and ejection of product by a method wherein the piston of a foremost stage is advanced stepwise by successively actuating an ejection cylinder by means of a plurality of pistons and at the same time reciprocated a plurality of times. CONSTITUTION:First, when injection process is started, a solenoid SOL (A) is actuated so as to change over the valve position of a change-over valve to the B side in order to supply working oil to a space part 5a. As a result, a piston 2a is advanced and similarly a piston 2c is also advanced by the prede termined stroke integrally with the piston 2a so as to seal a vent by blocking a vent groove 3 with a vent-sealing end 28a. Secondly, simultaneously with the finish of injection, the solenoid SOL (B) of a change-over valve 14 is actuat ed so as to advance the piston 2c by pressing it with a piston 2b and consequent ly a plate 27 in a mold further advances so as to cut off a gate part 33 with a gate cutting end 29a.

摘要： PURPOSE: To perform optimum inching operation in accordance with the lubricating oil temp. at the start of a hydraulic pump and also the type of the pump and make the subsequent continuous operation thereafter automatically. CONSTITUTION: The temp. of a working oil 2 is sensed by an oil temp. sensor 3 and through an A/D converter 4 an inching menu to suit the obtained oil temp. is selected by a sequencer 9 consisting of a CPU 5, ROM 6, and RAM 7. After execution of the selected inching menu, the continuous operation of a hydraulic pump 12 is conducted. Thereby accurate inching operation is performed in accordance with the working oil temp. at the start of the pump and its type, which should preclude the pump from failure including seizure, etc.

摘要： PURPOSE:To efficiently mold a specific color in one molding machine by disposing an injecting unit of a specific base provided at a stationary board side corresponding to specific number of mold units provided on a rotary table of a movable board, and coping with the switching of a stage. CONSTITUTION:First-third injecting units 13-15 are disposed at trisecting positions p1-p3 of a stationary board 12, the units 14, 15 are rotatably provided between 180 degree positions r1 to the positions p2, p3 and the first injecting unit. First, second and third molds 21, 22, 23 are mounted at the positions p1-p3 of a rotary table 11, and sequentially injection molded. When a three color molding is switched to a two color molding, the unit 14 is retreated, the unit 15 is rotatably moved from the position p3 to the position r1, a movable mold, first and second molds 26, 27 are mounted, and the table 11 is rotated at 180 degrees. Then, 1/2 section 33a of a molded form is obtained at a first stage A, and the remaining molded form is molded at a second stage thereby to obtain a 2 color molded form 33.
