  By the way, the applicant of this application is examining using a vertical clamp and a horizontal injection molding machine as a rotary table type injection molding machine suitable for manufacture of an insert-molded article. When manufacturing an insert-molded article using a rotary table type injection molding machine, a rotary which is a work bench to facilitate supply of insert parts to the mold apparatus and removal of the insert-molded article from the mold apparatus. It is required that the table be mounted on a fixed platen and be disposed at the center of the vertical mold clamping device in the height direction.

  That is, when the vertical mold clamping / horizontal injection molding machine is used as a rotary table type injection molding machine, the structure of the vertical mold clamping device vertically holds a plurality of tie bars in a fixed manner so as to be slidable. The movable platen is fixed to the upper end of the tie bar at the upper side, and the movable platen is secured to the lower end of the tie bar at the lower side of the stationary platen, and both ends of the toggle mechanism are connected to the stationary platen and the movable platen. Therefore, in the vertical mold clamping device according to the present configuration, when the toggle mechanism is extended, the movable platen and the movable platen are lowered and the fixed mold fixed to the upper surface of the fixed platen and the movable mold fixed to the lower surface of the movable platen When the mold is clamped and the toggle mechanism is contracted, the movable platen and the movable platen are raised to open the fixed mold and the movable mold. In this case, when it is attempted to inject and fill the molten resin into the cavity from the upper central portion of the movable mold, the vertical injection / horizontal injection molding machine lifts and lowers the horizontal injection device in synchronization with the elevation of the movable mold. It is necessary to provide a lifting mechanism to

  The elevating mechanism described in Patent Document 1 is for adjusting the height position of the injection mechanism according to the mold thickness, and is not for causing the injection mechanism to follow the movement of the movable mold, so a servomotor is used. There is no special problem when raising and lowering the injection mechanism. However, the movement of the movable mold, which is raised and lowered by driving the toggle mechanism, does not displace at a constant speed even when the operation part of the toggle mechanism is displaced at a constant speed using a servomotor etc. Since the movement is unique to the mechanism, it is practically difficult to use the servomotor to move the injection mechanism up and down to make the injection mechanism follow the movement of the movable mold. Then, if the injection mechanism can not accurately follow the movement of the movable mold, an excessive force repeatedly acts on the injection mechanism, which adversely affects the life of the mold clamping / horizontal injection molding machine.

  Further, the lifting mechanism described in Patent Document 1 has an injection nozzle attached to the tip of the heating cylinder via an L-shaped connecting member, and an injection nozzle using an abutment member provided on the upper surface of a fixed platen. There is also a problem that the cost is increased because a special structure of the heating cylinder and the abutting member are required since the above is pressed against the upper surface of the fixed mold.

  The present invention has been made to solve the problems of the prior art, and its object is to make it possible to make the moving up and down movement of the movable mechanism accurately follow the up and down movement of the movable mold at low cost. An object of the present invention is to provide a vertical mold clamping / horizontal injection molding machine.

The rotary portion of the first ball screw mechanism can be rotationally driven by a rotation amount corresponding to the elevation operation of the movable die plate. Therefore, if the first and second ball screw mechanisms having the same lead pitch are used, the straight movement portion of the first ball screw mechanism moves up and down the movable die plate in synchronization with the moving up and down of the movable die plate. It is moved up and down by the same amount. Therefore, regardless of the configuration of the toggle mechanism used and without providing a special drive source such as an electric servomotor or its control device, the elevation operation of the horizontal injection apparatus can reliably follow the elevation operation of the movable mold. It is possible to prevent the breakage of the horizontal injection device.

  As shown in FIGS. 1 and 2, the vertical mold clamping device 2 includes a base 11, a fixed die plate 12 fixed to the base 11 and arranged horizontally, and an outer peripheral portion of the fixed die plate 12. And a movable die plate 14 fixed to the upper end of the tie bar 13 above the fixed die plate 12, and a lower end of the tie bar 13 below the fixed die plate 12. The movable platen 15 is fixed to the movable platen 15. The toggle mechanism 16 is connected to the fixed die plate 12 and the movable platen 15 at both ends. The movable die plate 14 and the movable platen are disposed opposite to the fixed die plate 12.

  The rotary table 17 is rotatably provided on the fixed die plate 12, and the rotary table 17 is provided on the upper surface of the rotary table 17 at a point symmetrical position about the rotary shaft 17 a (one of the plurality of tie bars 13). Two fixed molds 18a, 18b are fixed. The rotary table 17 is intermittently rotationally driven by 180 degrees by driving a drive source (not shown) connected to the rotary shaft 17a, for example, an electric servomotor. On the other hand, on the lower surface of the movable die plate 14, one of the two fixed dies 18a and 18b fixed on the rotary table 17 (in the example of FIG. 1 and FIG. The movable mold 19 clamped with the fixed mold 18a) is fixed. The two fixed molds 18a and 18b are alternately moved to a position facing the movable mold 19 or a position separated from the movable mold 19 by intermittently rotating the rotary table 17 by 180 degrees. . Therefore, after supplying the insert part to the fixed mold 18b moved to the position separated from the movable mold 19, the fixed mold is alternately moved to the position opposed to the movable mold 19 and melted. By injection and filling of the resin, it is possible to manufacture a required insert-molded product.

  A hot runner block 20 is attached to the upper surface of the movable mold 19, as shown in an enlarged manner in FIG. In the hot runner block 20, a horizontal flow passage 21 penetrating to the side surface and a vertical flow passage 22 penetrating to the lower surface are formed in series, the open end of the horizontal flow passage 21 is an inlet for molten resin, the vertical flow passage 22 The open end of is the injection port of the molten resin. The injection nozzle 35 provided at the tip of the heating cylinder 34 is pressed against the molten resin injection port. Therefore, the molten resin supplied from the heating cylinder 34 is injected and filled into the cavity through the horizontal flow passage 21 and the vertical flow passage 22 of the hot runner block 20. The hot runner block 20 and the injection nozzle 35 are detachably fixed using a bolt or the like (not shown). As a result, the pressing state of the injection nozzle 35 against the hot runner block 20 can be stably maintained, so that occurrence of inconvenience such as resin leakage can be prevented in advance.

  The toggle mechanism 16 is a booster composed of a combination of a plurality of link members, and the cross head 16a provided at the connecting portion of the plurality of link members is a drive source (not shown) via a rod member 16b. A hydraulic cylinder or an electric servomotor or the like is connected. Since the toggle mechanism 16 is configured as described above, when the cross head 16a is driven upward by driving a drive source (not shown) to urge the crosshead 16a upward via the rod member 16b, the toggle mechanism 16 extends as shown in FIG. Then, the movable die plate 14 and the movable platen 15 are integrally lowered. Thereby, one of the fixed molds 18a and 18b and the movable mold 19 are clamped. On the other hand, when the cross head 16a is urged downward via the rod member 23, as shown in FIG. 2, the toggle mechanism 16 contracts and the movable die plate 14 and the movable platen 15 are integrally lifted. Do. Thereby, one of the fixed molds 18a and 18b and the movable mold 19 are opened.

  The horizontal injection device 3 includes a heating cylinder 34 and an injection nozzle 35 attached to the tip of the heating cylinder 34.

  The heating cylinder 34 is a cylindrical body provided with a heating body such as a band heater at its outer peripheral portion, and a screw (not shown) is rotatably and forwardly and backwardly accommodated in the internal space thereof. In the horizontal injection device 3, a raw resin supply portion for supplying the raw resin into the heating cylinder 34 from the distal end side of the heating cylinder 34, a screw rotating portion for rotationally driving a screw, and a screw in the length direction of the heating cylinder 34 A screw advancing and retracting unit is provided which is driven to move forward and backward. Therefore, when the screw rotation unit is driven to rotationally drive the screw in the heating cylinder 34, the raw material resin is automatically supplied from the raw material resin supply unit into the heating cylinder 34. The raw material resin supplied into the heating cylinder 33 is plasticized by heat generation of the heating body, shear heat generation accompanying rotation of the screw, and the like, and is sequentially transferred to the tip side of the injection nozzle 34 by the screw action. Then, when a predetermined amount of molten resin is stored in the space between the tip of the screw and the tip of the injection nozzle 34, the screw advancing and retracting part is driven to advance the screw toward the injection nozzle 35 at high speed. As a result, the molten resin stored in the space is injected from the injection nozzle 35 and injected and filled into the cavity through the horizontal flow passage 21 and the vertical flow passage 22 of the hot runner block 20.

  As shown in FIG. 1, FIG. 2 and FIG. 4, the lifting device 4 includes a first ball screw mechanism 46, a second ball screw mechanism 41, a rotating portion of the first ball screw mechanism 46, and a second mechanism. It comprises the timing belt 42 which connects with the rotation part of the ball screw mechanism 41.

  The first ball screw mechanism 46 is screwed with the first ball nut 47 fixed to the lift plate 32 and the first ball nut 47, and the lower end portion thereof is the base of the wedge clamping / horizontal injection molding machine 1 It comprises a first ball screw shaft 48 rotatably held by the portion 11. A first pulley 49 is fixed to a lower portion of the first ball screw shaft 48. When the first pulley 49 is driven to rotate, the first ball screw shaft is rotated according to the rotation direction. The first ball nut 47 screwed to 48 and the lift plate 32 fixed thereto are integrally raised or lowered.

  As shown in FIG. 4, in the present embodiment, two sets of first ball screw mechanisms 46 are installed at symmetrical positions via the horizontal injection device 3. Therefore, the horizontal injection device 3 according to the present embodiment can stably raise and lower the lift plate 32 while maintaining the horizontal state.

  The second ball screw mechanism 41 is screwed with the second ball nut 43 fixed to the movable die plate 14 and the second ball nut 43, and the lower end is rotatably held by the fixed die plate 12. The second ball screw shaft 44 and the second pulley 45 fixed to the lower portion of the second ball screw shaft 44. The timing belt 42, which is a power transmission member, is wound around the second pulley 45 and the first pulley 49 described above. Since the heating cylinder lifting mechanism 4 of this example uses a timing belt as a power transmission member, a wedge type clamping / horizontal injection molding machine having high operation reliability as compared with the case of using another power transmission mechanism such as a gear mechanism. 1 can be manufactured inexpensively. However, the power transmission member applicable to the heating cylinder lifting mechanism 4 is not limited to the timing belt 42, and other mechanisms such as a gear mechanism may be applied as needed.

  Hereinafter, the operation of the mold clamping / horizontal injection molding machine 1 according to the embodiment will be described.

  As described above, when the toggle mechanism 16 is extended, the movable die plate 14 is lowered, and when the toggle mechanism 16 is contracted, the movable die plate 14 is raised. Since the second ball nut 43 constituting the second ball screw mechanism 41 is fixed to the movable die plate 14, the second ball nut 43 moves up and down together with the movable die plate 14. In addition, when the second ball nut 43 moves up and down, the second ball screw shaft 44 constituting the second ball screw mechanism 41 and the second pulley 45 fixed to the same are rotated by an amount of rotation corresponding to the amount of movement. Will rotate. The rotation of the second pulley 45 is transmitted via the timing belt 42 to the first pulley 49 constituting the first ball screw mechanism 46 and the first ball screw shaft 48 to which the first pulley 49 is fixed. Then, when the first ball screw shaft 48 rotates, the first ball nut 37 and the elevating plate 32 to which the first ball nut 37 is fixed are moved up and down by an amount corresponding to the amount of rotation. Therefore, if the lead pitches of the first and second ball screw shafts 48 and 44 and the diameters of the first and second pulleys 49 and 45 are equal, the operation of the movable die plate 14 moved up and down by the toggle mechanism 16 The elevation of the elevation plate 32 can be accurately followed, and breakage of the horizontal injection device 3 can be prevented.

  That is, the movement of the movable mold 19 raised and lowered by driving the toggle mechanism 16 does not displace at a constant speed even when the crosshead 16a is displaced at a constant speed, as shown in FIG. It is a movement peculiar to the toggle mechanism. The vertical axis in FIG. 5 is a rod stroke indicating the displacement amount of the cross head 16 a, and the horizontal axis is a platen stroke indicating the displacement amount of the movable mold 19. As apparent from FIG. 5, when the toggle mechanism 16 is driven, the movable mold 19 is displaced so as to draw a tangent curve. For example, using the elevation mechanism 4 which is a combination of an electric servomotor and a ball screw mechanism It is practically difficult to make the elevation of the horizontal injection device 3 accurately follow the operation of the movable mold 19 even if a high-performance control device is used. On the other hand, the wedge clamping and lateral injection molding machine 1 according to the embodiment converts the displacement of the movable mold 19 into the amount of rotation of the first and second ball screw mechanisms 46 and 41, and further, Since it is converted to the displacement of the first ball screw mechanism 46 and transmitted to the elevating plate 32, the elevation of the horizontal injection device 3 is accurately performed to the operation of the movable die 19 even if the movable die 19 is not displaced linearly. It can be made to follow.

  Although the above embodiment has been described taking a rotary table injection molding machine as an example, the gist of the present invention is not limited to this, and as shown in FIG. The present invention can also be applied to vertical mold clamping / horizontal injection molding machines. The normal type vertical clamp / horizontal injection molding machine shown in FIG. 6 has the same configuration as the rotary table type injection molding machine 1 except that it does not have a rotary table, so in order to avoid duplication, FIG. The parts corresponding to those in FIG. 1 and FIG.
