Abstract

PURPOSE:To provide an injection molding machine which enables the taking off of moldings without providing a special driving source by arranging a mechanism adapted to actuate an arm for taking off the molding by a hydraulic pressure from a master cylinder in linkage with opening or closing the mold. CONSTITUTION:In opening the mold of an injection molding machine, as a platen 25 retreats, the rod of a master cylinder 1 is pushed through a bracket 11, a pad metal 8 and the like. An oil filled in the cylinder enters one end of a working cylinder 2 through a hydraulic hose 9. With such an arrangement, as a molding take off arm 18 is turned through the rod and a rotary actuator 17, a slide cylinder 20 advances. In the clamping thereof, the operation is reversed. As the hydraulic pressure in the cylinder 1 exceeds the specified value, the oil returns into an air hydraulic unit for automatic replenishment of oil from a relief valve to escape the pressure whereby the cylinder 1 is automatically replenished with oil.

DETAILED DESCRIPTION OF THE INVENTION It seems that a device for taking out a product from the lower part of an injection molding machine by a drive that is linked to the opening and closing of the mold has not been proposed in the past. Conventional take-out devices are installed at the top of the injection molding machine and operate by interlocking each operation using a separate drive source, which has the disadvantage of causing electrical and mechanical delays and lengthening cycle times. . Also, since it was installed on the top of the injection molding machine, it took up a lot of space, making it difficult to change molds from the top.

Next, to explain the operation of the embodiment described above, as shown in the figure, when the rond of the operating cylinder 2 is raised, the mold of the injection molding machine is open, and at this time, the mold of the injection molding machine is opened. A unit consisting of a push rod 5, a push bolt 6, a spring 7, and a bracket 11,
The dowel 8 attached to one side of the master cylinder l, which has both rondos, is pressed (the state shown in Figure 3). That is, the guide shaft 4 attached to the other side moves, causing the spring 3 to bend. At that time, the oil filled in the cylinder is transmitted through the hydraulic hose 9 to the operating cylinder 2.
enter and raise that rondo. At the same time as the cylinder 2 rises, the slide cylinder 2o moves forward and the take-out arm 18 clamps the workpiece. When the clamp is confirmed, the slide cylinder 2o moves back and waits.

Next, when the rond of the operating cylinder 2 is lowered, the ront of the master cylinder 1 is pushed by the deflecting spring 3 and follows the platen 25 at the same time as the mold of the injection molding machine begins to close. At that time, the oil filled in the cylinder passes through the hydraulic pressure hose and enters the other side of the working cylinder 2, and moves the waiting take-out arm 18 to the other side of the working cylinder 2.
Press down on the rondo to lower it. At the same time as the lowering, the take-out arm 18 is rotated 90 times by the row reactuator 17 to drop the workpiece onto the belt conveyor, and then the take-out arm 18 is reversed by 90'' and stands by.

As explained in detail above, the present invention is structured such that a master cylinder and a driven cylinder are connected, and the filled oil is linked to the opening and closing of the mold of an injection molding machine, and the oil in the master cylinder is transferred to the driven cylinder by this movement. This eliminates the need for other power sources, resulting in energy savings. Furthermore, since it moves in conjunction with the opening and closing of the mold, it operates without interlocking the raising and lowering of the take-out arm, which shortens the take-out time and shortens the molding cycle.

Furthermore, since the take-out device is made compact and takes out from the bottom, it fits inside the injection molding machine, and the injection molding machine itself becomes compact. In addition, because it is taken out from the bottom, it is easy to change the mold from the top, and the oil that exceeds a certain pressure can be released.
Furthermore, since the released oil is automatically replenished into the cylinder and the insufficient oil is automatically replenished, it is possible to prevent unreasonable operation of the device.
