Driving means 10a and 10b are provided at both ends of the mold 6 along the Za direction of the molding part 32, respectively. The driving means 10 a and 10 b correspond to a reversing and moving device that is assembled to the resin member 1 held by the molding portion 31 by reversing and moving the piece mold 32 a while holding the molded resin member 2. The detailed configuration of the driving means 10a and 10b will be described in detail below.

  In the molding and assembling apparatus of the present embodiment, for example, one of the mold 5 and the mold 6 is fixed as a fixed mold to a frame of an injection molding machine, and another mold is fixed to the fixed mold. Can be configured as a movable mold. In the present embodiment, for convenience, the mold 5 is configured as a fixed mold fixed to a gantry of an injection molding machine, and the mold 5 is connected to an unillustrated molten resin injection mechanism of the injection molding machine. Shall.

  As shown in FIG. 2A, the molding and assembling apparatus of the present embodiment includes a plurality of (four in this example) guides 501 extending in the left-right direction in FIG. The guide 501 is fixed with respect to the mold 5 that is a fixed mold, for example, and guides the mold 6 that is a movable mold through the mold 6. For example, by controlling the position of the mold 6 on the guide 501 by an appropriate drive system of an injection molding machine (not shown), for example, the rotating mold 6 and the mold 5 are moved relative to each other, and mold clamping or mold opening is performed. can do.

  Next, the molding and assembling operation in the above configuration and the method for manufacturing the component 200 will be described. In the present embodiment, the resin members 1 and 2 shown in FIG. 1 are formed through the first step to the fourth step, united, and unitized into a component 200. Hereinafter, each of these steps will be described.

  First, the first step will be described with reference to FIGS. FIG. 5 shows a state where the molds 5 and 6 are closed. 6A shows a state after the molds 5 and 6 are closed, and FIG. 6B shows a cross section (horizontal cross section) along the line AA in FIG. 6A. . FIG. 7 shows a state in which the resin members 1 and 2 are injection-molded in the same manner as in FIG.

  In the first step (molding step), as shown in FIG. 5, the mold 6 is moved in the X1 direction of the mold 5, that is, in a direction close to each other, and the mold 5 and the mold 6 are closed. For the movement of the mold, driving means arranged in an injection molding machine (not shown) is used. However, the relative movement of the molds 5 and 6 is such that the mold 5 is moved if the mold 6 is mounted as a fixed mold in an injection molding machine (not shown). May be.

  6A and 6B show a state after the molds 5 and 6 are closed. In particular, FIG. 6B shows a horizontal cross section (line AA in FIG. 6A) of the molds 5 and 6 in the mold closed state. As shown in FIG. 6B, in this mold closed state, the molding parts 21 and 22 of the mold 5 and the molding parts 31 and 32 of the mold 6 face each other and closely contact each other, and the resin member 1 is between them. , Cavities 80a and 80b for molding 2 respectively.

  As described above, the molding parts 31 and 32 of the mold 6 are specifically configured by the piece molds 31a and 32a. Hereinafter, for the sake of convenience, the molding part 31 to the piece mold 31a may be referred to as a first molding part, and the molding part 32 to the piece mold 32a may be referred to as a second molding part.

  In the present embodiment, among these molded parts, at least the second molded part (32, particularly the piece mold 32 a) is configured to be removable from the mold 6. And this 2nd shaping | molding part (32, especially piece type | mold 32a) is removed from the metal mold | die surface of the metal mold | die 6 by the drive means 10a, 10b as a reversing movement apparatus, and it is reversed and moved with respect to a metal mold | die surface. be able to. Thereby, as described later, the second molding part (32, in particular, the piece mold 32a) is reversed and moved so as to face the first molding part (31, in particular, the piece mold 31a). Assemble the resin members 2 and 1 molded in the above.

  Subsequently, as shown in FIG. 7, molten resin is injected into a plurality of cavities 80 a and 80 b formed respectively by the molding parts 21 and 22 of the mold 5 and the molding parts 31 and 32 of the mold 6. Then, as shown in FIG. 7, a plurality of resin members 1 and 2 are injection molded. For example, an injection mechanism (not shown) of an injection molding machine connected to the mold 5 is used for the injection of the molten resin.

  Next, a 2nd process is demonstrated using FIG. 8, FIG. This second process corresponds to a preparation stage of a third process (assembly process) to be described later, and is mainly a process of opening the molds 5 and 6. FIG. 8 shows a state in which the molds 5 and 6 are opened, and FIG. 9 shows a state in which the resin members 1 and 2 that are injection-molded in the molding parts 31 and 32 are held.

  In this second step, as shown in FIG. 8, the mold 6 is relatively moved in the X2 direction away from the mold 5 to open the mold. At this time, as shown in FIG. 9, the resin members 1 and 2 are released from the molding parts 21 and 22 of the mold 5 and are held in the molding parts 31 and 32 of the mold 6, respectively. In order to open the mold in such a manner, the holding force of each mold is determined in advance by selecting a mold shape to be arranged on each side of the mold 6 and the mold 5. Alternatively, if necessary, a structure in which a release pin or the like is arranged on the mold 5 side may be used.

  Next, a 3rd process (assembly process) is demonstrated using FIG. 9, FIG. FIG. 10 corresponds to a top view from the Z1 direction of FIG. In this third step (assembly step), the resin member 2 held by the molding part 32 of the mold is applied to the resin member 1 held by the molding part 31 on the mold surface using the driving means 10a and 10b. Then, the resin member 2 is assembled to the resin member 1 by being reversed and moved.

  FIGS. 10A to 10C are views for reversing and moving the second molded part (32, particularly the piece mold 32a) so as to face the first molded part (31, particularly the piece mold 31a). FIG. 10 shows the configuration and operation of the upper drive unit 10a in FIG. The structure of the driving means 10b is the same as that of the driving means 10a except that the vertical relationship of the member arrangement is reversed. In FIG. 10A, the driving means 10a has a U-shaped groove 50a provided as a guide portion. Shafts 40a and 40b are projected from the upper end surface of the molding portion 32 (piece mold 32a) and engaged with the groove 50a.

  On the other hand, a lever 51a is fixed to the rotating shaft of the gear 121a (FIGS. 11A and 11B), and the lever 51a is engaged between the shafts 40a and 40b. The gear 121a meshes with the gear 120a, and although not shown in detail, the gear 120a is rotationally driven by a drive source such as an electric motor. The rotational drive directions of the gears 120a and 121a in the third step (assembly step) are Ra and Rb (FIGS. 10A and 10B). With such a structure, when the lever 51a of the driving means 10a is swung, as shown in FIGS. 10A, 10B, and 10C, the shaft 40a protruding from the molding portion 32 (piece mold 32a) is provided. , 40b move along the groove 50a.

  Accordingly, as shown by two-dot chain lines in FIGS. 10A, 10 </ b> B, and 10 </ b> C, the molding portion 32 (piece mold 32 a) that holds the resin member 2 is used as the mold of the mold 6. It is removed from the surface, reversed and moved with respect to the mold surface, and controlled to a position and posture facing the molding part 31 (piece mold 31a).

  As described above, the molding unit 32 (the piece mold 32a) is reversed and moved with respect to the mold surface by the driving unit 10a, and the resin member 2 held by the molding unit 32 (the piece mold 32a) is moved to the molding unit 31. It can be made to oppose the (member type | mold 31a) and the resin member 1 hold | maintained. And the resin member 2 can be assembled | attached to the resin member 1 by further pressing the shaping | molding part 32 (piece | die type 32a) with the drive means 10a. It is assumed that the resin member 2 and the resin member 1 are injection-molded with a fitting structure (click stop) such as a protrusion to a groove that can be coupled by the driving force of the driving means 10a. The operation of the driving means 10a on the upper side of the molding part 32 (piece mold 32a) has been described above, but it goes without saying that the driving means 10b on the lower side of the molding part 32 (piece mold 32a) also operates in the same manner. .

  Next, a fourth step of releasing the molded and assembled part 200 and taking it out will be described with reference to FIGS. 11A and 11B show the operation of the driving means 10a when releasing the resin member 2 from the molding portion 32, and FIG. 12 shows the molded and assembled component 200 from the mold 6. The operation of releasing is shown.

  For example, after the component 200 having a space inside is assembled from the resin members 1 and 2 as described above, the molded part 32 is formed as shown in FIGS. 10 (c), 10 (b), and 10 (a). Operate in reverse order. FIG. 11A is a perspective view showing a state where the driving means 10a is located at a position corresponding to FIG. 10B, and FIG. 11B is a perspective view.

  In this fourth step, the rotational driving directions of the gears 120a and 121a of the driving means 10a are Rc and Rd (FIG. 11A). Although not shown in detail, it goes without saying that the driving means 10b also performs the same operation. When the driving means 10a (and 10b) is operated in the opposite direction to the above Ra and Rb as described above, the resin member 2 becomes the molded portion 32 (as shown in FIGS. 10C, 10B, and 10A). The mold is released from the piece mold 32a). Then, the assembled component 200 remains on the molding part 31 (piece mold 31a) side (FIG. 11B).

  In order to form such a mold release form, the bonding (holding) force between the resin member 2 and the resin member 1 assembled in the third step (assembly step) is based on the holding force between the molded portion 32 and the resin member 2. It only needs to be large. Such a bonding (holding) force between the resin member 2 and the resin member 1 can be easily obtained by selecting design conditions for a fitting structure (such as a click stop) between them.

  Further, as shown in FIG. 12, the component 200 is released by the ejector pin 100 built in the mold 6, and the molded and assembled component 200 can be taken out from the molding and assembling apparatus.

  As described above, according to the present embodiment, the resin members 1 and 2 constituting the component 200 include the first molding part 31 arranged side by side on the same mold surface and the first removable from the mold surface. The two molding parts 32 are injection-molded in the same molding process. For this reason, the resin members 1 and 2 can be injection-molded with extremely high accuracy. Further, in the present embodiment, the second molding part 32 is removed from the mold surface by the driving means 10 a and 10 b (reversing movement device), and reversed and moved with respect to the mold surface of the mold 6. Then, the second molded part 32 is opposed to the first molded part 31, and the resin member 2 molded by the second molded part 32 is attached to the resin member 1 molded by the first molded part 31. . Thus, in this embodiment, since the resin members 1 and 2 are assembled on one mold surface of the mold 6 while being held by the holding portion of the mold 6, highly accurate assembly can be realized. Therefore, the component 200 can be manufactured with high accuracy.

<Embodiment 2>
Next, the mold having the first and / or second molding portion on the mold surface is configured as a rotating mold, and sequentially rotated to a plurality of process positions to execute a molding or assembling process. The structure of a shaping | molding assembly apparatus is shown. At the process position where the mold surface of the rotating mold is rotated, a different manufacturing process is performed for manufacturing the component by moving the manufacturing mechanism relative to the first and / or second molding part. A plurality of manufacturing mechanisms are arranged at a plurality of different process positions around the rotary mold in the order of processes. The plurality of manufacturing mechanisms execute different manufacturing processes for manufacturing the part by moving relative to the molding part. The molds 5a and 7a and the slide molds 7a and 7b, which will be described later, are used as the manufacturing mechanism. Equivalent to.

  Hereinafter, the configuration and operation of the second embodiment will be described with reference to FIGS. In the second embodiment, the above-described resin members 1 and 2 are further combined with another resin member (molded member) and integrated.

  FIG. 13 shows a component 200a to be molded in this embodiment. The component 200a is a component that constitutes a component of the image forming apparatus, and includes a resin member 1a, a resin member 2a, and a bonding member 4. The component 200a is, for example, a cleaning unit or a developer unit used for a cartridge of the image forming apparatus. In the present embodiment, the resin members 1a and 2a and the joining member 4 are molded and assembled by injecting molten resin by a molding and assembling apparatus to be described later, and are integrated (unitized) to become parts of the image forming apparatus. In a state where 200a is integrated (unitized), the resin member 1a and the resin member 2a are joined by the joining member 4.

  First, the configuration of a molding and assembling apparatus for assembling the component 200a, particularly the mold configuration, will be described with reference to FIGS. 14A shows the entire molding and assembling apparatus, and FIG. 14B corresponds to a top view of the molding and assembling apparatus shown in FIG. 14A viewed from the Zb direction. 15 shows the structure of the front surface of the mold 5a having a molding portion (viewed from the left side of FIG. 14A), and FIG. 16 shows the first molding surface 30a of the rotating mold 6a (FIG. 14 ( The structure of the front) seen from the right side of a) is shown.

  As shown in FIGS. 14A and 14B, the mold includes a mold 5 a having a molded part, a rotating mold 6 a having a molded part supported by the frame 11, and a mold 7. In the present embodiment, the frame 11 and the rotating mold 6a are positioned with high accuracy by arranging the frame 11 with respect to the center of the rotating shaft 90 of the rotating mold 6a.

  Of these molds, for example, one of them can be fixed as a fixed mold to a frame of an injection molding machine, and the other two molds can be configured as movable molds with respect to this fixed mold. . In the present embodiment, for convenience, the mold 5a is configured as a fixed mold fixed to a gantry of an injection molding machine, and a molten resin injection mechanism (not shown) of the injection molding machine is connected to the mold 5a. It shall be.

  The frame 11 is a frame body having, for example, four support columns as shown in the figure, and the rotary mold 6a is supported rotatably with respect to the frame 11 with the rotation shaft 90 as a rotation center. The rotary mold 6a is rotated around the rotation shaft 90 so as to take a specific rotation position in the R direction, for example, by a drive unit 12 including, for example, an electric motor and a transmission mechanism disposed at the lower portion of the frame 11. Can be positioned.

  The rotary mold 6a has at least two or more molding surfaces, and can be rotated by the drive unit 12 to, for example, a plurality of process positions 150a and 150b in FIG. In the present embodiment, the entire rotary mold 6a has a substantially quadrangular prism shape, and has two molding surfaces 30a and 30b each having the same first and second molding parts on opposite mold surfaces. Further, at the process position 150 (FIG. 14B), the injection unit 9 is arranged in the mold 7 in order to injection mold the joining member 4 of the component 200a.

  In the present embodiment, the rotary mold 6a is provided with two molding surfaces 30a and 30b having the same first and second molding parts. This means that the manufacturing process of two identical parts 200a can proceed on the same rotating mold 6a. However, three or more molding surfaces equivalent to the molding surfaces 30a and 30b may be arranged on the rotary mold 6a. In that case, the manufacturing process of three or more same components 200a can be advanced.

  As shown in FIGS. 14A and 14B, the molding and assembling apparatus of this embodiment includes a plurality of (four in this example) guides 501 extending in the left-right direction in FIG. In this embodiment, the guide 501 is fixed with respect to the mold 5a which is a fixed mold, and the guide 501 penetrates the frame 11 and the mold 7 as shown in the figure. Then, for example, by controlling the positions of the frame 11 and the mold 7 on the guide 501 by an appropriate drive system of an injection molding machine (not shown), for example, the rotating mold 6a and the mold 5a, or the rotating mold. The mold 6a and the mold 7 can be moved relative to each other and clamped or opened.

  In the present embodiment, the mold 5a is a fixed mold as described above, but this is for convenience, and the rotating mold 6a and the mold 5a or the rotating mold 6a Any structure that can move relative to the mold 7 may be used. For this relative movement, any of the molds 5a and 7 and the rotating mold 6a or the frame 11 that supports the molds may be configured as a fixed mold (or a movable mold). Alternatively, the structure may be such that both of the two relatively moving molds move, and even if all the molds are movable molds, the configuration of the present invention is not affected.

  In addition, the molding and assembling apparatus of the present embodiment has a first process position 150a and a second process position 150b. Here, the direction in which the molds 7, 6a and 5a are opened and closed is defined as the X direction, and the direction perpendicular to the X direction is defined as the Y direction (FIG. 14B).

  In the molding and assembling apparatus according to the present embodiment, the mold clamping or the mold is synchronized with the relative movement between the manufacturing mechanism (for example, the mold 5a) and one mold surface (molding surface 30a or 30b) of the rotating mold 6a. First slide molds 7a and 7b to be opened are provided (FIG. 14A). The first slide molds 7a and 7b are moved relative to each other between the rotating mold 6a and the manufacturing mechanism (for example, the mold 5a) via the angular pins 70a and 70b (FIG. 17) at the first process position 150a. It is driven using. For this reason, the relative movement between the slide molds 7a and 7b and the rotary mold 6a does not require a drive source such as a motor, a solenoid, or an air cylinder, and the apparatus can be configured easily and inexpensively.

  As shown in FIG. 15, the mold 5a has molding parts 21a and 22a as parts for molding the resin members 1a and 2a, respectively. Further, as shown in FIG. 16, the rotary die 6a has pieces 31a and 32a as parts for forming the resin members 1a and 2a on the first forming surface 30a, and the pieces 31a and 32a are formed of the die 5a. It arrange | positions facing the shaping | molding parts 21a and 22a. These members functionally correspond to the members of the first embodiment having the same reference numerals in the portions excluding the suffix “a” of the respective reference numerals.

  In FIG. 14A, the first molding surface 30a of the mold 6a is located at a process position 150a facing the molding parts 21a and 22a of the mold 5a. However, by rotating the rotary mold 6a by the drive unit 12, the second molding surface 30b can be positioned at the process position 150a, and at the same time, the first molding surface 30a is positioned at the process position 150b (advanced). )be able to.

  In the second embodiment, the second molding part 32 (piece mold 32a) of the mold 6a functionally corresponding to the driving means 10a, 10b of the first embodiment is located at a position corresponding to the process position 150b. Driving means 100a and 100b are arranged as a reversing movement device. In the present embodiment, the driving means 100a and 100b are attached to the frame 11 instead of the mold 6a. For this reason, in the present embodiment, the driving means 100a, 100b (reversing movement device) simultaneously move relative to the second molding part (piece mold 32a) of the mold 6a to manufacture the component. It can also be said that it constitutes a manufacturing mechanism for executing different manufacturing processes.

  Next, a method for molding and assembling the resin member of the present invention will be described. In the second embodiment, the resin members 1a and 2a and the joining member 4 shown in FIG. 13 are molded and assembled through the first to fourth steps, and the component 200a is manufactured.

  First, the first step will be described with reference to FIGS. FIG. 17 shows a state when the mold is closed, and FIG. 18A shows a state when the mold is closed. 18B shows a cross section along the line AA in FIG. 18A, and FIG. 18C shows a cross section along the line BB in FIG. 18A. FIG. 19A shows a cross section taken along the line AA in FIG. 18A, and FIG. 19B shows a cross section taken along the line BB in FIG. 18A.

  In the first step (molding step), as shown in FIG. 17, the rotating mold 6a, the frame 11, and the mold 7 are moved in the X51 direction toward the mold 5a, so that the mold 5a and the rotating mold 6a are molded. Close. (First process position 150a: FIG. 14B). At the same time, the slide molds 7a and 7b arranged on the frame 11 are moved in the direction of Zu1 and Zb1 by the angular pins 70a and 70b attached to the mold 5a, and contact the rotating mold 6a. Thereby, the upper and lower sides of the cavity 80a defined by the molding part 21a of the mold 5a and the piece mold 31a of the rotating mold 6 are sealed. By such a structure using the slide molds 7a and 7b, for example, even a resin member having a relatively complicated shape at both ends can be injection-molded.

  Next, in this clamping state, as shown in FIGS. 18B and 18C, the molding parts 21a and 22a of the mold 5a, the piece molds 31a and 32a of the rotating mold 6a, and the slide molds 7a and 7b. The molten resin is injected into the plurality of cavities 81a and 81b formed by the above. Thereby, as shown to Fig.19 (a), (b), several resin member 1a, 2a is shape | molded.

  Next, a 2nd process is demonstrated using FIG.18, FIG.20, FIG.21. 20 shows a state in which the mold is opened, and FIG. 21 shows a state in which the piece molds 31a and 32a hold the molded resin members 1a and 2a.

  In this second step, as shown in FIG. 20, the mold 7 and the rotating mold 6a are moved in the X52 direction away from the mold 5a to open the mold. In synchronization with this, the slide molds 7a and 7b are moved by the angular pins 70a and 70b in the directions of Zu2 and Zb2 in FIG. 18B, which are separated from the rotary mold 6a. Further, as shown in FIG. 21, the resin members 1a and 2a are released from the molding portions 21a and 22a of the mold 5a while being held by the piece molds 31a and 32a of the rotating mold 6a.

  Next, the third step will be described with reference to FIGS. 17 and 22 to 26. FIG. 22 shows a state where the rotary mold 6a is being rotated. FIG. 23 (a) shows the operation of the driving means 100a. FIG. 23B shows the H portion of FIG. 23A in an enlarged manner, and corresponds to the state before the driving means 100a as the reversing movement device is operated. FIG. 23C is an enlarged view of the portion H in FIG. 23A, and corresponds to a state after the driving means 100a is operated. 24A to 24C correspond to FIGS. 10A to 10C of the first embodiment, and show how the piece 32a is reversed and moved by the driving means 100a and 100b (reversing movement device). ing. 25 (a) and 25 (b) correspond to a state in which the joining member 4 is molded, and shows a horizontal cross section of the molding and assembling apparatus from FIG. 17 onward. FIG. 26 shows a different configuration in which an injection unit 9a having a function equivalent to that of the injection unit 9 (FIGS. 17 and 20) is arranged on the frame 11a side.

  The third step includes a rotation operation that advances one mold surface (for example, the molding surface 30a or 30b) of the rotating mold 6a from the process position 150a to 150b after the first and second steps. Further, it includes assembly by reversal and movement of the molding part 32 (piece mold 32a) by the driving means 100a, and joining operation of the resin member 1a and the resin member 2a by the joining member 4.

  In this third step, first, as shown in FIG. 22, with the molded resin member 1a and the resin member 2a held by the rotary mold 6a, the rotary mold 6a is centered on the rotary shaft 90 in the R direction. Rotate 180 °. Thereby, one mold surface (for example, molding surface 30a or 30b) of the rotating mold 6a is moved from the process position 150a to 150b.

  Next, as shown in FIG. 23A, the driving means 100a and 100b arranged in the frame 11 are moved in the Z21 and Z22 directions, respectively. Thus, the upper and lower end faces 39a and 39b of the piece mold 32a of the rotating mold 6a are brought into contact with each other. For this reason, the driving means 100a (same for 100b) is provided with a moving means 111b in which, for example, an air cylinder and an angular pin are combined. For example, as shown in FIG. 23 (b)-> FIG. 23 (c), the driving means 100a is lowered (the driving means 100b is raised) by moving the moving means 111b in the Y21 direction.

  On the other hand, the piece mold 32a (second molding portion for the resin member 2a) includes shafts 41a and 41b on the upper end surface 39a in contact with the driving means 100a. Although not shown in detail, the piece mold 32a is provided with similar shafts 41a and 41b on the lower end surface 39b in contact with the driving means 100a. Then, by bringing the driving means 100a and 100b close to the piece mold 32a, the shafts 41a and 41b of the piece mold 32a are guided into the guide groove of the driving means 100a (same for 100b) as shown in FIGS. 53a (refer FIG. 24) is penetrated, and it engages with the lever 52a.

  Thereafter, as shown in FIGS. 24A to 24C, the drive means 100a and 100b are replaced with the piece mold 32a (second molding portion for the resin member 2a) in the same manner as the drive means 10a and 10b of the first embodiment. It operates as a reversing movement device.

  In this initial state, as shown in FIG. 24 (a), the shafts 41a and 41b of the frame 32a are engaged with the guide groove 53a of the driving means 100a and the lever 52a of the driving means 100a is engaged. .

  The driving means 100a of this embodiment includes a gear 122a that is rotationally driven in the Ra1 direction and a gear 123a that is integrated with the lever 52a. The gear 122a is rotationally driven in the Ra1 direction by the same electric motor as in the above embodiment, the meshing gear 123a rotates in the Rb1 direction, and the lever 52a is moved as shown in FIGS. 24 (a), (b), and (c). Rotate. Thereby, the lever 52a contacts the shaft 41a, and the shafts 41a and 41b are moved along the U-shaped guide groove 53a.

  Here, the piece mold 32a is configured to be removable from the mold surface (the molding surface 30a or 30b) of the rotating mold 6a as in the first embodiment. Accordingly, the piece mold 32a is formed by assembling the resin member 2a held by the piece mold (31a) to the resin member 1a as shown in FIG. 24 (b)-> (c) while holding the molded resin member 2a. To be attached, it is reversed and moved on the mold surface. That is, since the piece mold 32a moves along the U-shaped groove 53a, the resin member 2a held by the piece mold 32a is inverted so as to be turned over 180 ° when contacting the resin member 1a. As described above, since the resin member 2a is in a position facing the resin member 1a, the resin member 2a can be moved to the assembly position with respect to the resin member 1a by rotating to the state shown in FIG. it can.

  Thereafter, the mold 7 is moved along the guide 501 in the X51 direction (FIG. 17) toward the rotating mold 6a (and the frame 11), and the mold 7 and the rotating mold 6a are closed. At this time, it is assumed that the mold 7 is provided with a recess capable of accommodating the frame mold 32a moved to the position of FIG. In this state, the resin member 1a and the resin member 2a are joined by the joining member 4.

  Specifically, as shown in FIG. 25A, after the piece mold 32a holding the resin member 2a and the piece mold 31a holding the resin member 1a are overlapped, the mold 7 and the rotating mold 6a are closed. Thus, the mold 7 presses the piece mold 32a. Thereby, the surfaces 1b and 2b which the resin member 1a and the resin member 2a face each other are brought into close contact with each other. Next, as shown in FIG. 25 (b), the cavity member 81d (FIG. 25 (a)) formed by the resin member 1a, the resin member 2a, and the piece mold 32a is filled with the joining member 4, whereby the resin member 1a and the resin member 2a are joined.

  An injection unit 9 disposed in the mold 7 is used for filling the molten resin constituting the joining member 4. Alternatively, instead of the injection unit 9, an injection unit 9a having an equivalent injection function may be arranged on the frame 11a side. Moreover, you may employ | adopt the process assembled instead of filling of the joining member 4 by the mutual fitting thru | or engagement (for example, click stop structure) of the resin member 1a and the resin member 2a as demonstrated in Embodiment 1. FIG.

  As described above, also in this embodiment, the resin members 1a and 2a constituting the component 200a can be detached from the first molding portion 31 (31a) arranged in parallel on the same mold surface and the mold surface. The second molding part 32 (32a) is injection-molded in the same molding process. For this reason, the resin members 1a and 2a can be injection-molded with extremely high accuracy. Furthermore, in this embodiment, the second molding part 32 (32a) is removed from the mold surface by the driving means 100a, 100b (reversing movement device), and reversed and moved with respect to the mold surface of the rotating mold 6a. The second molding part 32 (32a) is opposed to the first molding part 31 (31a). And the metal mold | die 7 and the rotation metal mold | die 6 are clamped, the joining member 4 is filled, and the resin member 2a and the resin member 1a are joined. Thus, also in this embodiment, since the resin members 1a and 2a are assembled on one mold surface of the rotating mold 6a while being held by the holding portion of the rotating mold 6a, highly accurate assembly is possible. realizable. Therefore, the component 200a can be manufactured with high accuracy.

  Next, a 4th process is demonstrated using FIG.20, FIG.23, FIG.24 and FIG. The fourth step corresponds to a step of releasing the piece mold 32a from the resin member 2a (component 200a). FIGS. 27A and 27B show a state in which the piece mold 32a and the resin member 2a are released in the same manner as in FIG. 11 of the first embodiment.

  First, the mold 7 and the rotating mold 6a are moved along the guide 501 in the X52 direction (FIG. 20) away from the mold 5a to open the mold. Subsequently, in the order of FIGS. 24C, 24B, and 24A, the piece mold 32a is again reversed and moved in the reverse direction by the driving means 100a and 100b, and the state shown in FIG. Return to the state of 24 (a). By this operation, the resin member 2a is released from the piece mold 32a and remains on the side of the component 200a held by the piece mold 31a.

  Specifically, as shown in FIGS. 27A and 27B, the gear 122a of the driving unit 100a is rotationally driven in the Rc1 direction (at this time, the driving unit 100b is also operated similarly). As a result, the gear 1223a for driving the lever 52a rotates in the Rd1 direction, the lever 52a comes into contact with the shaft 41b, and the piece 32a is reversed (in the opposite direction again) as shown in FIG. Moving. That is, the piece mold 32a is reversed and moved in a direction away from the component 200a in which the resin members 1a and 2a are already joined by the joining member 4.

  At this time, the resin member 2 a has already been joined to the resin member 1 a by the joining member 4. Since the joining force is superior to the holding force of the piece mold 32a and the resin member 2a, the piece mold 32a is separated (released) from the resin member 2a, and the initial position (molding surface 30a) of the rotary mold 6a is obtained. Or return to 30b). Thereafter, the driving means 100a and 100b are moved away from the upper and lower ends of the piece mold 32a in the order shown in FIGS. 23C and 23B, that is, in the direction opposite to the above.

  Next, the fifth step will be described with reference to FIGS. 13 and 28 to 29. This fifth step corresponds to a step of releasing the component 200a and taking it out. FIG. 28 shows a side surface (from the left side of FIG. 17) of the molding and assembling apparatus in a state where the resin members 1a and 2a are released from the rotary mold 6a. FIG. 29 shows a state where molding and assembly are performed at the process positions 150a and 150b using the two molding surfaces (30a and 30b) of the rotary mold 6a.

  In the fifth step, as shown in FIG. 28, at the second step position 150b, the completed component 200a is released by the ejector pin 101b built in the rotary mold 6a and taken out from the molding and assembling apparatus. The drive source of the ejector pin 101b may be arranged on the frame 11 side in addition to being arranged in the rotary mold 6a. As described above, the manufacture of the component 200a in which the resin members 1a and 2a as shown in FIG. 13 are assembled is completed.

  According to the second embodiment, a plurality of mold surfaces (molding surfaces 30a, 30b) of the rotating mold 6a are provided with a first molding part (31a) and a second molding part (detachable from the mold surface). The same structure with 32a) is arranged. In the second embodiment, the molding surfaces 30a and 30b constitute opposing mold surfaces of the substantially quadrangular prism-shaped rotary mold 6a. Therefore, in this embodiment, as shown in FIG. 29, the resin members 1d and 2d are used in the first process position 150a in a state where the rotary mold 6a and the frame 11, the mold 7 and the mold 5a are closed. Can be injection molded. At the same time, at the second process position 150b, the resin member 1a and the resin member 2b can be assembled by reversing and moving the second molding portion 32 (piece mold 32a).

  That is, according to the rotating mold structure of the second embodiment, the manufacturing process can be sequentially and simultaneously performed by two (or more) molding surfaces having the same shape, and the molding assembly apparatus can be manufactured. Efficiency can be significantly improved. In addition, since the resin parts 1a and 2a, which are injection-molded using the molding parts (piece molds 31a and 32a) arranged side by side on the same mold surface, are combined with each other, high-accuracy assembly can be realized. A high-quality component 200a can be manufactured.

<Modification>
In the second embodiment described above, a configuration in which two different molding surfaces (30a, 30b) having the same configuration are arranged on the rotary mold 6a is shown. However, depending on the number of steps of parts to be manufactured, the rotary mold 6a Any number of molding surfaces (30a...) May be arranged. Further, for example, the configuration may be such that injection molding and assembly are performed using only three of the four surfaces of the quadrangular prism-shaped rotating mold 6a. Although the mechanism for mold opening and closing may be complicated, the entire rotary mold 6a may have the same molding surface on the n side surfaces, for example, an n-prism shape. . With such a configuration, the manufacturing process can be sequentially and simultaneously performed by n molding surfaces having the same shape, and the manufacturing efficiency of the molding and assembling apparatus can be significantly improved.

  In the first and second embodiments, as the reversing and moving device of the second molding part (32 or piece mold 32a) that can be removed from the mold surface, the driving means 10a, 10b having a U-shaped groove as a guide, 100a, 100b, etc. are shown (FIGS. 10 and 24). However, this reversal moving device removes one molding part so that the resin members 1 (1a) and 2 (2a) which are molded and held by the two molding parts are opposed to each other, and with respect to the mold surface. Any configuration that can be reversed and moved is acceptable. In the two embodiments described above, the second molding part that can be removed from the mold surface is the molding part 32 or the piece mold 32a. However, this is merely for convenience. Of course, a functionally equivalent or equivalent manufacturing process can be executed even if the molding unit 31 or the piece mold 31a is not the molding unit 32 or the piece mold 32a but the side of the molding unit 31 or the piece mold 31a is reversed and moved by the reversing and moving device. .

  In addition, the form of the trajectory and the posture change when one of the first and second molding parts (piece molds) juxtaposed on the same mold surface is reversed and moved with respect to the mold surface by the reversing movement device, It is not necessary to have a shape defined by the U-shaped guide described above. FIG. 30 and FIG. 31 show an example of the form of trajectory and posture change when one of the forming parts, for example, the second forming part (piece mold 320) is reversed and moved. 30 and 31 show the functional structure of the reversing and moving device, and not the specific structure of the reversing and moving device. As long as the structure can be realized, the detailed structure of the inversion moving device is not limited.

  30 (a), 30 (b), 31 (a), and 31 (b), the piece mold 310 and the piece mold 320 are the same as the first molded portion (31 or piece mold 31a) in the above embodiment. 2 corresponding to the two molding parts (32 or piece mold 32a). The piece mold 310 and the piece mold 320 are juxtaposed on the same mold surface (not shown). On the other hand, in this example, for example, the piece mold 320 can be removed from the mold surface and can be reversed and moved. A rotation shaft 900 is used. The rotating shaft 900 is coupled to a rotation driving means (not shown) (such as an electric motor and a speed reducer). By rotating the rotating shaft 900, the piece 320 is turned 180 ° from the initial state of FIG. Can be reversed.

  The piece mold 310 and the piece mold 320 face a pair of molds (not shown), are clamped, and mold the resin members 1aa and 2aa corresponding to the resin members 1 (1a) and 2 (2a) by injection molding. To do. In FIGS. 30A and 30B, the resin members 1aa and 2aa correspond to the state after being molded on the piece mold 310 and the piece mold 320, respectively.

  FIG. 30B shows an outline of a trajectory for reversing and moving the piece mold 320. A guide 800 indicated by a two-dot chain line in the drawing has a U-shaped shape, engages with the rotation shaft 900 of the piece mold 320, and determines a trajectory for reversing and moving the piece mold 320. The portion corresponding to the two U-shaped arms of the guide 800 passes through the center of the piece mold 310 and the center of the piece mold 320 at the initial position indicated by the two-dot chain line as shown in the figure. For example, the guide 800 is formed on the substrate of the driving means 10a, 10b (or 100a, 100b) that constitutes the above-described reversal moving device. The drive means 10a, 10b (or 100a, 100b) also has a drive means (not shown) (electric motor and speed reducer, cam mechanism or chain mechanism) for moving the rotary shaft 900 of the piece 320 along the guide 800. Etc.) shall be provided. The mechanism for moving the block molds 310 and 320 is arranged at an arbitrary part of the molding and assembling apparatus such as one of the molds (not shown) for holding the block molds 310 and 320 and the outside. Can do.

  In the above configuration, first, the resin member 1aa is formed on the piece mold 310 and the resin member 2aa is formed on the piece mold 320 as shown in FIG. Subsequently, as illustrated in FIG. 30B, the piece mold 320 that holds the resin member 2 aa moves in the X200 direction along the movement guide 800. Subsequently, as shown in FIG. 31A, the piece mold 320 is rotated 180 in the Re direction around the rotation axis 900 at an appropriate position sufficiently separated from the mold surface (not shown) on which the piece mold 320 is held. ° Invert. In this example, the rotating shaft 900 is provided on the piece mold 320 in this embodiment, but the rotating shaft 900 may be installed outside the piece mold 320.

  Further, as shown in FIG. 31B, the piece mold 320 is sequentially moved from the position of FIG. 31A (two-dot chain line) along the guide 800 along the movement guide 800 in the Y200 direction and then in the X210 direction. Move. As a result, it is matched with the piece mold 310 (solid line), and the resin members 1aa and 2aa are joined. As described above, the resin members 1aa and 2aa can be combined. As described above, the resin members 1aa and 2aa are joined by the engagement or fitting structure described in the first embodiment, filling of the joining member (4) described in the second embodiment, or the like.

  Further, for example, the components 200 and 200a illustrated in FIGS. 1 and 13 of the first and second embodiments are cleaning units used for a cartridge of an image forming apparatus, for example. As described above, these parts 200 and 200a are integrated by assembling the resin members molded in the same process on the same mold surface by the reversing movement device of the molding part (piece type). Such a manufacturing process is significantly different from a conventional process of assembling parts formed by cavities existing on separate mold surfaces using ultrasonic welding or the like in a random combination in a subsequent process. That is, in the above embodiment, when assembling one component, the mating partner is limited to the resin member molded on the same mold surface, so that highly accurate assembly can be performed.

  Moreover, the parts manufactured by the molding and assembling apparatus employing the present invention are not limited to shapes such as the parts 200 and 200a shown in FIGS. 1 and 13 of the first and second embodiments. For example, the component 201a that forms the developer unit used in the cartridge of the image forming apparatus having the shape as shown in FIG. 32 can be manufactured by the same manufacturing process as described above. 32 includes resin members 201 and 202 as developing parts. According to the structure equivalent to Embodiment 1, 2, these resin members 201 and 202 can be simultaneously injection-molded on the molding part (piece shape) juxtaposed on the same die surface. For this reason, the component 201a can be assembled with high accuracy from the resin members 201 and 202 which are formed in the same process and have limited combinations to be joined.

  In the second embodiment using the rotating mold 6a, for example, as shown in FIG. 17, the rotating shaft 90 of the rotating mold 6a is arranged along the vertical (vertical) direction. As schematically shown in FIG. 33A, this configuration is equivalent to a configuration in which a rotating shaft 90e that supports the rotating mold 6e is arranged along the ZG direction with respect to a frame 11e that is a vertical (vertical) axis. It is. FIG. 33 (b) corresponds to the top view of FIG. 33 (a), but in this configuration, as shown in the figure, the rotating shaft 90e is rotated in the Re direction to rotate the rotating mold 6e. .

  However, it is not essential to arrange the rotating shaft 90 (90e) of the rotating mold 6a (6e) along the vertical (vertical) axis, and the rotating shaft 90 (90e) is arbitrary with respect to the vertical (vertical) axis. It may be inclined at an angle. For example, FIGS. 34 (a) and (b) are the same as FIGS. 33 (a) and (b), but as shown in FIG. 34, the rotating shaft that supports the rotating mold 6f with respect to the frame 11f. 90f may be arranged. 34A and 34B, the rotating shaft 90f that supports the rotating mold 6f with respect to the frame 11f is disposed along the YG direction (perpendicular to the vertical axis, that is, the horizontal direction). . In this configuration, as shown in FIG. 34B, the rotating shaft 90f is rotated in the Rf direction, and the rotating mold 6f is rotated. According to such a configuration, for example, the lower part of FIGS. 34 (a) and 34 (b) is used as a process position for releasing and taking out the part, thereby allowing the part to be released and taken out of the manufactured part. There is a possibility that it can proceed well.

  Also, for example, the size of the rotating mold 6e shown in FIGS. 33A and 33B is increased, and the above-described first and second molding parts are not limited to one set, but a plurality of sets, the rotating mold 6e. It may be arranged on one mold surface. In that case, a reversal moving device for reversing and moving the second forming portion is arranged for each set. With such a configuration, for example, two sets of parts (or more sets) can be obtained, and the manufacturing efficiency of the molding and assembling apparatus can be greatly improved.

  Further, as shown in FIGS. 35 (a) and 35 (b), a configuration in which a plurality of rotating dies are arranged is also conceivable. FIGS. 35A and 35B show the configuration of a molding and assembling apparatus in which two rotating dies 6g1 and 6g2 are arranged. The rotating molds 6g1 and 6g2 are configured to rotate in the Rg1 and Rg2 directions around the rotating shafts 90g1 and 90g2, respectively. The rotating molds have the same configuration as shown in FIGS. 14 to 29, for example. Can be arranged. Even with such a configuration, the manufacturing efficiency of parts of the molding and assembling apparatus can be remarkably improved.

<Control system and control procedure of molding assembly apparatus>
Here, with reference to FIGS. 36 to 38, an example of a control system configuration applicable to the molding and assembling apparatus of each of the above-described embodiments and a control procedure related to the manufacture of parts will be described.

  Hereinafter, an example of a control procedure for controlling the manufacturing process of the component (200, 200a) in each of the above embodiments will be described with reference to FIGS.

  FIG. 37 shows the first and second molding parts (31, 32, 31a) of the mold (the mold 6 of the first embodiment, the rotary mold 6a of the second embodiment) executed by the control device of FIG. , 32a) shows an example of injection molding, and control of a manufacturing process involving reversal and movement. As the reversing and moving device for the first and second forming portions (31, 32, 31a, 32a), the above-described driving means (10a, 10b in the first embodiment, 100a, 100b in the second embodiment) are used.

  In steps S01 and S02 in FIG. 37, the resin member 1 (1a) and the resin member 2 (2a) are respectively formed by the first molding part (31, 31a) and the second molding part (32, 32a). Injection molding. In the figure, for convenience, a format in which steps S01 and S02 are sequentially executed is used. However, in an actual apparatus, clamping, casting, and mold opening are performed simultaneously.

  When the injection molding of the resin member 1 (1a) and the resin member 2 (2a) in steps S01 and S02 is completed, the mold opening is performed. After that, in step S03, the second molding part (32 or piece mold 32a) is moved with respect to the mold surface by the driving means (10a, 10b of the first embodiment, 100a, 100b of the second embodiment) as a reversal moving device. Reverse and move. Thereby, the 2nd shaping | molding part (32 thru | or piece type | mold 32a) opposes the 1st shaping | molding part (31 thru | or piece type | mold 31a).

  Thereafter, in step S04, the resin member 2 (2a) held by the second molding section (32 or piece mold 32a) and the molded resin held by the first molding section (31 or piece mold 31a). The member 1 (1a) is assembled and coupled. The coupling between the resin member 1 (1a) and the resin member 2 (2a) is based on the pressing force by the driving means (10a, 10b in the first embodiment, 100a, 100b in the second embodiment) as described in the first embodiment, for example. It is performed by fitting or engagement. Alternatively, the resin member 1 (1a) and the resin member 2 (2a) are joined by, for example, filling the bonding member 4 as described in the second embodiment.

  By the control procedure as shown in FIG. 36, the resin members 1 (1a) and 2 (2a) are arranged in parallel on the same mold surface of the mold 6 (6a), and the first and second molding portions 31 are arranged. , 32 (31a, 32a) in the same molding process. Therefore, the resin members 1 (1a) and 2 (2a) can be injection molded with extremely high accuracy. Further, the resin members 1 (1a) and 2 (2a) are held on the mold surface of the mold 6 (6a) while being held by the holding unit of the mold 6 (6a) using the reversal moving device. Since it is assembled, highly accurate assembly can be realized. Therefore, the component 200 (200a) can be manufactured with high accuracy.

  FIG. 38 shows an outline of a control procedure related to the production of the part 200a by the molding / assembly apparatus using the rotating mold 6a of the second embodiment, which is executed by the control apparatus of FIG. The illustrated procedure can be stored in the above-mentioned storage means such as the ROM 602 as a control program of the CPU 601. In the following description, for example, a plurality of molding surfaces 30a, 30b (...) arranged on the rotary mold 6a are considered as a first surface and a second surface (...), respectively, and the general expression of "nth surface" Use such expressions. Similarly, the “m-th process position” is used as a general expression of the first, second,..., Process positions 150a, 150b (...). In FIG. 38, for the sake of simplification, the manufacturing process (up to component removal) for the molding surface of the nth surface is shown, but the manufacturing process for the (n + 1) th surface and the (n + 2) th surface (...) is the same. At the same time.

  38, the CPU 601 uses the drive unit 12 of the drive device 611 (drive system) to rotate the rotary mold 6a (90 ° in the arrangement shown in FIG. 20), and the molding surfaces 30a, 30b,. The n-plane is moved to the m-th process position. As is apparent from the above-described configuration of the rotating mold 6a, the rotating operation of the rotating mold 6a causes the (n + 1) th surface and the (n + 2) th surface (... ) (For example, FIG. 22).

  In steps S12 to S13, the CPU 601 is configured to drive the molding / assembly apparatus drive device 611 (drive system) and the injection molding device 612 (injection system) at the m-th process position with respect to the n-th surface of the molding surface (30a, 30b...). ) To control the m-th step. At the same time, the corresponding process positions can be executed at the (m + 1) th process position, the (m + 2) th process position, and the (m + 3) th process position (...) With respect to the other molding surfaces.

  If it is confirmed in step S13 that the mth process has been completed, the CPU 601 determines in step S14 whether or not all the processes for the nth surface have been completed. When all the processes for the nth surface have been completed in step S14, in step S15, the component 200a has been moved to the take-out position (150b in the above example), where the component of the component by the ejector pin (100) is moved. Take out. On the other hand, if all the processes for the nth surface have not been completed in step S14, the CPU 601 advances the control data of the counter (or pointer etc.) for managing the process position to point to the next process in step S16. (M = m + 1). Thereafter, the control returns to step S11, and the above operation is repeated to execute the (m + 1) th step, the (m + 2) th step, the (m + 3) th step (...) For the nth surface (30a, 30b...). it can.

  By executing a control procedure as schematically shown in FIG. 38 using a control system as shown in FIG. 36, the manufacturing steps are sequentially performed with n molding surfaces having the same shape with a delay or advance of one step. In addition, it can proceed simultaneously. Therefore, the manufacturing efficiency of the molding and assembling apparatus can be remarkably improved by the configuration as shown in FIGS.
