These are arranged sequentially from the bottom to the top. The lower fixed platen 42, the movable platen 44 and the upper fixed platen 43, which are horizontally arranged with substantially rectangular thick plates, have guide bars 45 passing through the four corners thereof, and the lower fixed platen 42 at both ends of the guide bar 45. The movable platen 44 is connected to the tip of the piston rod of the movable platen drive device 46 installed on the upper fixed platen 43 so that the movable platen 44 can move in the vertical direction between them.

Thus, a mold 47 is configured. The upper fixed platen 43 is provided with an operation / control device 49. Further, the mold 47 is connected to a conventional peeling device (not shown) that is arranged separately from the main body of the molding device 4.

  The lower fixed platen 42 of the molding device 4 is provided with a support 50 on the side end surface on the coating device 3 side, facing the direction of the coating device 3 (X-axis direction). On the upper surfaces of the lower fixed platen 42 and the support base 50, the X-axis direction guide rod 51 is provided horizontally in the X-axis direction on one side or both sides in the Y-axis direction. The X-axis direction guide rod 51 supports and guides a lower portion of the Z-axis direction moving device 34 provided in the discharge unit 32, and the Z-axis direction moving device 34 linearly reciprocates in the X-axis direction. It is configured to be able to.

  As shown in some examples in FIGS. 2 to 4, the X-axis direction guide rod 51 is variously configured depending on the size of the molded body, that is, the planar size of the mold 47. That is, FIG. 2 shows a configuration when the molded body is small, a configuration in which one X-axis direction guide rod 51 is provided on one side, and FIG. 4 shows a configuration when the molded body is large, each on both sides. FIG. 3 shows an intermediate configuration in which one X-axis direction guide bar 51 is provided, and FIG. 3 shows a configuration in which two X-axis direction guide rods 51 are provided on one side. The lip portion 32a is lifted by the reaction force of the thermoplastic resin material discharged from the lip portion 32a of the discharge portion 32 onto the molding surface of the fixed mold 47a, that is, the lip portion 32a and the molding surface of the fixed mold 47a. Since the gap changes, it is necessary to prevent this. Accordingly, an appropriate configuration of the X-axis direction guide rod 51 is selected according to the planar size of the mold 47, that is, the width of the lip width of the lip portion 32a. Therefore, the size of the coating device 3 can be increased by changing only the shape of the guide bar 51.

  In the manufacturing apparatus 1 configured as described above, the molded body is manufactured as follows. That is, when all the devices of the coating device 3 and the molding device 4 are adjusted and the thermoplastic resin raw material is supplied and ready for operation, the position of the lip portion 32a of the discharge portion 32 is first adjusted. . That is, with the mold 47 of the molding device 4 opened, the X-axis drive device 33d, the Y-axis drive device 33e and the Z-axis direction movement device 34 of the three-dimensional moving gantry 33 are appropriately operated to After the portion 32a is moved forward (in the X-axis direction), the tip (lower end) of the lip portion 32a is in a state of retreating with a predetermined (molding surface) position and a predetermined distance on the surface of the fixed mold 47a while maintaining a predetermined gap. Realize and set its operating conditions.

When adjusting the position of the lip portion 32a, in the X-axis direction, the X-axis moving table 33a is moved in the X-axis direction by the X-axis driving device 33d, and in the Y-axis direction, the Y-axis moving table 33b is moved in the Y-axis driving device 33e. Thus, adjustment is performed by reciprocating linearly in the Y-axis direction. Regarding the Z-axis direction, the Z-axis moving table 33c supported by the rotating support 33g via the discharge unit 32 and the tip of the Y-axis moving table 33b is moved by the Z-axis moving device 34 to the rotating support 33g. Since the support point (support shaft) is reciprocally rotated (elevated), as shown in FIG.

  Next, in a state where the mold 47 of the molding apparatus 4 is opened, the three-dimensional moving gantry 33 is operated to advance the lip portion 32a of the discharge section 32 to the molding end of the fixed mold 47a. While the molten thermoplastic resin material supplied to the portion 32 is discharged from the lip portion 32a, a predetermined gap is maintained and the predetermined distance is retracted. When the predetermined distance is retracted, the discharge of the thermoplastic resin raw material is stopped, and the discharge is further retracted and stopped until at least the tip of the discharge portion 32 reaches the outside of the mold 47. That is, while the lip portion 32a of the discharge portion 32 is retracted from the molding end of the fixed mold 47a to the near side, the molten thermoplastic resin material discharged from the lip portion 32a is formed on the molding surface of the fixed mold 47a. It is applied to the shape.

  Further, in the molding device 4, when the operation / control device 49 is operated to operate the movable platen drive device 46 and the movable platen 44 is lowered, the movable die 47b is lowered and superposed with the fixed die 47a, and the mold The mold 47 is closed. With this mold 47 closed, press molding is performed with a predetermined pressing force and a predetermined time. Thereafter, while operating the peeling device (not shown), the movable platen drive device 46 is operated to raise the movable platen 44. As the movable platen 44 rises, the movable mold 47b rises and the mold 47 opens. The peeled molded body is taken out from the opened mold 47, and the production of the molded body is completed.

At the time of manufacturing the above molded body, the weights of the plasticizing part 31, the discharge part 32, and the devices attached to them are supported by the rotating support 33g near the center of gravity in the X-axis direction. The portion is configured to be able to reciprocate around the Y axis of the rotary support 33g. Therefore, only a small load in the Z-axis direction is applied to the Z-axis direction moving device 34 provided in the discharge unit 32. As a result, the tip end portion of the discharge portion 32, that is, the position of the lip portion 32a in the Z-axis direction can be easily moved and controlled with small power. Further, a small load is applied to the X-axis direction guide rod 51 for guiding the Z-axis direction moving device 34, and easy guidance with high clearance accuracy is performed. Therefore, as a result of the experiment, the position of the three-dimensional moving gantry 33 can be controlled within an allowable range of 100 μm in the X- axis direction and the Y-axis direction and 10 μm in the Z-axis direction.

  The air cylinder 33h, which is provided in parallel with the rotary support 33g in the X-axis direction of the X-axis moving table 33a and supports the Z-axis moving table 33c, elastically supports changes in weight balance during operation. To buffer. Further, the air cylinder 33h absorbs and cancels backlash between the devices and members constituting the three-dimensional moving mount 33 and related devices. As a result, the entire manufacturing apparatus 1 can be operated smoothly and stably, and a high-quality molded product can be efficiently manufactured.

  Therefore, since the position control mechanism using the above-described three-dimensional moving gantry 33 combines the arcuate motion of the elevation (Z-axis) with the linear motion of the X-axis of the coating device 3, the vertical trajectory of the discharge unit 32 is quasi-linear. It can be operated.

In addition, when an example carried out by the present applicant is described, when an acrylic resin or a polystyrene resin is used, the plasticizing temperature is 300 ° C. or higher, and the molded resin product accurately transfers a fine uneven shape from several hundred nm. it is possible to obtain the formation form.
