It is a figure which shows the state with which the saddle mold clamping apparatus frame by one Embodiment of this invention, and the saddle injection apparatus frame were connected. It is a figure which shows the state with which the vertical mold clamping apparatus frame of FIG. 1 and the horizontal injection apparatus frame were connected. It is a figure which shows the state with which the horizontal injection apparatus frame of FIG. 2 and the horizontal mold clamping apparatus frame were connected.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In the drawings, the same or corresponding components are denoted by the same or corresponding reference numerals, and description thereof is omitted.

  FIG. 1 is a view showing a state in which a saddle mold clamping device frame and a saddle injection device frame according to an embodiment of the present invention are connected. The frame 30 of the injection molding machine is divided into a saddle mold clamping device frame 31 that supports the saddle mold clamping device 10 and a saddle injection device frame 32 that supports the saddle injection device 20.

  The saddle mold clamping apparatus 10 performs mold closing, mold clamping, and mold opening of the mold apparatus 40. The saddle mold clamping device 10 is a mold clamping device in which the mold clamping direction is the vertical direction. The vertical mold clamping device 10 includes a lower platen 12 as a fixed platen, an upper platen 13 as a movable platen, a support platen 15, a tie bar 16, a toggle mechanism 17, a mold clamping motor 18, and the like.

  The lower platen 12 is fixed to the vertical mold clamping device frame 31. The lower platen 12 rotatably supports the rotary table 14 from below. A plurality of (for example, two) lower molds 42 are attached to the upper surface of the rotary table 14. The plurality of lower molds 42 are arranged at an equal pitch around the rotation center of the rotary table 14.

  The upper platen 13 is movable up and down above the lower platen 12. An upper mold 43 is attached to the lower surface of the upper platen 13. The lower mold 42 and the upper mold 43 constitute a mold apparatus 40.

  By moving the upper platen 13 up and down relative to the lower platen 12, the mold device 40 is closed, clamped, and opened. A cavity space for molding a molded product is formed between the lower mold 42 and the upper mold 43 facing each other. By rotating the rotary table 14, each lower mold 42 moves between a position where the molded product is molded and a position where the molded product is taken out. Molding of the molded product and taking out of the molded product can be performed simultaneously. The position for taking out the molded product from the lower mold 42 may also serve as a setup position for setting the insert part in the lower mold 42.

  The support platen 15 is movable up and down below the lower platen 12. The support platen 15 is connected to the upper platen 13 via a plurality of (for example, three) tie bars 16.

  The toggle mechanism 17 is disposed between the lower platen 12 and the support platen 15 and is attached to each of the lower platen 12 and the support platen 15. The toggle mechanism 17 raises and lowers the upper platen 13 together with the support platen 15 by expanding and contracting in the vertical direction.

  The mold clamping motor 18 raises and lowers the upper platen 13 together with the support platen 15 by operating the toggle mechanism 17. The rotational movement of the mold clamping motor 18 is converted into a linear movement in the ball screw mechanism and transmitted to the toggle mechanism 17.

  The mold closing motor 18 lowers the upper platen 13 to close the mold. After the mold closing is completed, a mold clamping force is generated by multiplying the propulsive force of the mold clamping motor 18 by the toggle magnification, and the mold clamping is performed by the mold clamping force. A cavity space is formed between the lower mold 42 and the upper mold 43 at the time of mold clamping, and the soot injection device 20 fills the cavity space with a liquid molding material. The molding material in the cavity space is solidified and becomes a molded product. Thereafter, the mold clamping motor 18 raises the upper platen 13 to open the mold.
