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

In the molding and assembling device of the present embodiment, for example, any one of the mold 5 and the mold 6 is fixed as a fixed mold to the pedestal of the injection molding machine, and the other 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 frame or the like of an injection molding machine, and the mold 5 is connected to an injection mechanism of molten resin (not shown) of the injection molding machine. It shall be.

As shown in FIG. 2A, the molding and assembling apparatus of this embodiment includes a plurality of guides 501 (four in this example) extending in the left-right direction of the figure. The guide 501 is fixed to, for example, the fixed mold 5, and guides the movable mold 6 through the mold 6.

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

First, the first step will be described with reference to FIGS. 5 to 7. FIG. 5 shows a state when the molds 5 and 6 are closed. FIG. 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 of FIG. 6A. .. Further, FIG. 7 shows a state in which the resin members 1 and 2 are injection-molded in the same format as in FIG. 6 (b).

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. A driving means arranged in an injection molding machine (not shown) is used to move the mold. However, regarding the relative movement of the molds 5 and 6, if the mold 6 is mounted as a fixed mold on the injection molding machine (not shown), the mold 5 is moved. You may.

6 (a) and 6 (b) show the state after the molds 5 and 6 are closed. In particular, FIG. 6B shows the horizontal cross sections (lines 6A-A) of the molds 5 and 6 in this mold closed state. As shown in FIG. 6B, in this mold closed state, the molding portions 21 and 22 of the mold 5 and the molding portions 31 and 32 of the mold 6 face each other and are in close contact with each other, and the resin member 1 is between the two. Cavities 80a and 80b for molding 2 and 2, respectively, are defined.

As described above, the molding portions 31 and 32 of the mold 6 are specifically composed of the piece molds 31a and 32a. In the following, for convenience, the molding portion 31 or the piece mold 31a may be referred to as a first molding portion, and the molding portion 32 or the piece mold 32a may be referred to as a second molding portion.

In the present embodiment, at least the second molded portion (32, particularly the piece mold 32a) of these molded portions is configured to be removable from the mold 6. Then, the second molding portion (32, particularly the piece mold 32a) is removed from the mold surface of the mold 6 by the driving means 10a and 10b as the reversing moving device, and is inverted and moved with respect to the mold surface. be able to. As a result, as will be described later, the second forming portion (32, particularly the piece mold 32a) is inverted and moved so as to face the first forming portion (31, particularly the piece mold 31a), and each forming portion is inverted. Assemble the resin members 2 and 1 formed in 1.

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

Next, the second step will be described with reference to FIGS. 8 and 9. This second step corresponds to the preparatory step of the third step (assembly step) described later, and is a step of mainly opening the molds 5 and 6. FIG. 8 shows a state in which the dies 5 and 6 are opened, and FIG. 9 shows a state in which the injection-molded resin members 1 and 2 are held in the molding portions 31 and 32, respectively.

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 portions 21 and 22 of the mold 5, and are held by the molding portions 31 and 32 of the mold 6, respectively. In order to open the mold in such an manner, the holding force of each mold is determined in advance by selecting the mold shape to be arranged on each side of the mold 6 and the mold 5. Alternatively, if necessary, a structure may be used in which a release pin or the like is arranged on the mold 5 side.

Next, the third step (assembly step) will be described with reference to FIGS. 9 and 10. FIG. 10 corresponds to the top view of FIG. 9 from the Z1 direction. In this third step (assembly step), the resin member 2 held by the molding portion 32 of the mold is placed on the mold surface by using the driving means 10a and 10b on the resin member 1 held by the molding portion 31. The resin member 2 is assembled to the resin member 1 by inverting and moving with.

10 (a) to 10 (c) are for inverting and moving the second forming portion (32, particularly the piece mold 32a) so as to face the first forming portion (31, particularly the piece mold 31a). , The configuration and operation of the upper drive means 10a in FIG. 9 are shown. 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 are 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 details are not shown, 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, the shaft 40a projecting from the molding portion 32 (piece shape 32a) as shown in FIGS. 10A, 10B, and 10A. , 40b move along the groove 50a.

Along with this, as shown by the two-dot chain line in FIGS. 10A, 10B, and 10C, the molding portion 32 (piece mold 32a) holding the resin member 2 is the mold of the mold 6. It is removed from the surface, inverted and moved with respect to the mold surface, and controlled to a position and orientation facing the molding portion 31 (piece mold 31a).

As described above, the molding portion 32 (piece mold 32a) is inverted and moved with respect to the mold surface by the driving means 10a, and the resin member 2 held by the molding portion 32 (piece mold 32a) is moved to the molding portion 31. The (piece type 31a) and the held resin member 1 can be opposed to each other. Then, the resin member 2 can be assembled to the resin member 1 by further pressing the molding portion 32 (piece mold 32a) by the driving 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 protrusions and grooves that can be coupled by the driving force of the driving means 10a. In the above, the operation of the drive means 10a on the upper side of the molding portion 32 (piece mold 32a) has been described, but it goes without saying that the drive means 10b on the lower side of the molding portion 32 (piece mold 32a) also operates in the same manner. ..

Next, a fourth step of releasing and taking out the molded and assembled parts 200 will be described with reference to FIGS. 10 to 12. 11 (a) and 11 (b) show the operation of the driving means 10a when the resin member 2 is released from the molding portion 32, and FIG. 12 shows the molded and assembled parts 200 from the mold 6. Shows the operation of releasing the mold.

After the parts 200 having a space inside are assembled from the resin members 1 and 2 as described above, the molded portion 32 is formed as shown in FIGS. 10 (c), (b), and (a). Operate in reverse order. Further, FIG. 11 (a) shows a state in which the driving means 10a is located at a position corresponding to FIG. 10 (b) and FIG. 11 (b) is a perspective view.

In this fourth step, the rotational drive directions of the gears 120a and 121a of the drive 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 direction opposite to that of Ra and Rb described above, the resin member 2 becomes the molded portion 32 (as shown in FIGS. 10 (c), (b) and (a)). It is released from the piece type 32a). Then, the assembled part 200 remains on the molding portion 31 (piece mold 31a) side (FIG. 11 (b)).

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 determined by the holding force of the molding portion 32 and the resin member 2. The bigger it is. Such a bonding (holding) force between the resin member 2 and the resin member 1 can be easily obtained by selecting the design conditions of the fitting structure (click stop or the like) between the two.

Further, as shown in FIG. 12, the part 200 can be released from the ejector pin 100 built in the mold 6 and the molded and assembled part 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 are the first molding portion 31 juxtaposed on the same mold surface and the first mold surface removable from the mold surface. Injection molding is performed in the same molding process by the molding unit 32 of 2. Therefore, the resin members 1 and 2 can be injection-molded with extremely high accuracy. Further, in the present embodiment, the second molding portion 32 is removed from the mold surface by the driving means 10a and 10b (reversing moving device), and is inverted and moved with respect to the mold surface of the mold 6. Then, the second molded portion 32 is opposed to the first molded portion 31, and the resin member 2 molded by the second molded portion 32 is attached to the resin member 1 molded by the first molded portion 31. .. As described above, in the present embodiment, 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, so that highly accurate assembly can be realized. Therefore, the component 200 can be manufactured with high accuracy.

In FIG. 14A, the first molding surface 30a of the mold 6a is located at the process position 150a facing the molding portions 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 can be positioned at the process position 150b (advance). )be able to.

Further, in the second embodiment, the second forming portion 32 (piece mold 32a) of the mold 6a, which functionally corresponds to the driving means 10a and 10b of the first embodiment, is located at the position corresponding to the process position 150b. Drive means 100a and 100b are arranged as the reverse movement device. In the present embodiment, the driving means 100a and 100b are mounted on the frame 11 instead of the mold 6a. Therefore, in the present embodiment, the driving means 100a and 100b (reversing moving device) simultaneously move relative to the second molding portion (piece mold 32a) of the mold 6a to manufacture the parts. It can be said that it constitutes a manufacturing mechanism that executes different manufacturing processes.

Next, the molding and assembling method of 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. 17 to 19. FIG. 17 shows a state when the mold is closed, and FIG. 18A shows a state when the mold is closed. 18 (b) shows a cross section along the line AA of FIG. 18 (a), and FIG. 18 (c) shows a cross section along the line BB of FIG. 18 (a). 19 (a) shows a cross section along the line AA of FIG. 18 (a), and FIG. 19 (b) shows a cross section along the line BB of FIG. 18 (a).

In the first step (molding step), as shown in FIG. 17, the rotary mold 6a, the frame 11, and the mold 7 are moved in the X51 direction toward the mold 5a to mold the mold 5a and the rotary mold 6a. Close. (First step position 150a: FIG. 14B). At the same time, the slide dies 7a and 7b arranged on the frame 11 are moved in the directions of Zu1 and Zb1 by the angular pins 70a and 70b attached to the dies 5a and come into contact with the rotary dies 6a. As a result, the molding portion 21a of the mold 5a and the upper and lower parts of the cavity 80a defined by the piece mold 31a of the rotary mold 6 are sealed. With such a structure using the slide dies 7a and 7b, injection molding is possible even for a resin member having a relatively complicated shape at both ends, for example.

Next, in this mold-fastened state, as shown in FIGS. 18B and 18C, the molding portions 21a and 22a of the mold 5a, the piece molds 31a and 32a of the rotary 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. As a result, a plurality of resin members 1a and 2a are molded as shown in FIGS. 19A and 19B.

Next, the second step will be described with reference to FIGS. 18, 20, and 21. FIG. 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 resin members 1a and 2a after molding.

In this second step, as shown in FIG. 20, the mold 7 and the rotary mold 6a are moved in the X52 direction away from the mold 5a to open the mold. In synchronization with this, the angular pins 70a and 70b move the slide dies 7a and 7b in the direction of Zu2 and Zb2 in FIG. 18B away from the rotary dies 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 rotary mold 6a, respectively.

Next, the third step will be described with reference to FIGS. 17, 22 to 26. FIG. 22 shows a state in which the rotary mold 6a is rotated. FIG. 23A shows the operation of the driving means 100a. FIG. 23 (b) shows an enlarged portion H of FIG. 23 (a), and the drive means 100a as the reversing moving device corresponds to the state before the operation. FIG. 23 (c) shows an enlarged portion H of FIG. 23 (a), which corresponds to a state after the driving means 100a operates. 24 (a) to 24 (c) correspond to FIGS. 10 (a) to 10 (c) of the first embodiment, and show a state in which the piece type 32a is inverted and moved by the driving means 100a and 100b (reversing moving device). ing. Further, FIGS. 25 (a) and 25 (b) correspond to a state in which the joining member 4 is molded, and the horizontal cross sections of the molding assembly apparatus after FIG. 17 are shown from below. FIG. 26 shows a different configuration in which the injection unit 9a having the same function as the injection unit 9 (FIGS. 17 and 20) is arranged on the frame 11a side.

The third step includes, after the first and second steps, a rotation operation of advancing one mold surface (for example, molding surface 30a or 30b) of the rotary mold 6a from the process position 150a to 150b. It also includes assembling by reversing and moving the molded portion 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, the rotating mold 6a is held in the rotating mold 6a in the state where the molded resin member 1a and the resin member 2a are held in the rotating mold 6a in the R direction. Rotate 180 °. As a result, one mold surface (for example, molding surface 30a or 30b) of the rotary mold 6a is moved from the process position 150a to 150b.

Next, as shown in FIG. 23A, the drive means 100a and 100b arranged in the frame 11 are moved in the Z21 and Z22 directions, respectively. As a result, the upper and lower end surfaces 39a and 39b of the piece mold 32a of the rotary mold 6a are brought into contact with each other. Therefore, for example, the driving means 100a (same for 100b) is provided with a moving means 111b in which 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 (the second molding portion for the resin member 2a) includes the shafts 41a and 41b on the upper end surface 39a in contact with the driving means 100a. Although not shown in detail, it is assumed that the piece type 32a is provided with the same shafts 41a and 41b on the lower end surface 39b in contact with the driving means 100a. Then, by bringing the drive means 100a and 100b close to the piece type 32a, the shafts 41a and 41b of the piece type 32a become the guide grooves of the drive means 100a (the same applies to 100b) as shown in FIGS. 23 (b) and 23 (c). It penetrates 53a (see FIG. 24) and engages with the lever 52a.

After that, as shown in FIGS. 24 (a) to 24 (c), the driving means 100a and 100b are mounted on the driving means 10a and 10b of the first embodiment, and the piece mold 32a (second molding portion for the resin member 2a). Operates as a reversing moving device.

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

The drive means 100a of the present 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 an electric motor or the like similar to the above embodiment, the meshing gear 123a rotates in the Rb1 direction, and the lever 52a is moved as shown in FIGS. 24A, 24B, and 24C. Rotate. As a result, the lever 52a comes into contact with the shaft 41a, and the shafts 41a and 41b are moved along the U-shaped guide groove 53a.

Here, the piece mold 32a has a configuration that can be removed from the mold surface (molding surface 30a or 30b) of the rotary mold 6a as in the first embodiment. Therefore, in the piece mold 32a, while the molded resin member 2a is held, the resin member 2a held by the piece mold (31a) is assembled to the resin member 1a as shown in FIGS. 24 (b)-> (c). Inverted and moved on the mold surface to attach. That is, since the piece shape 32a moves along the U-shaped groove 53a, the resin member 2a held by the piece shape 32a is inverted so as to be turned inside out by 180 ° when it comes into contact with the resin member 1a. Since the resin member 2a is located at a position facing the resin member 1a as described above, the resin member 2a can be moved to the assembly position with respect to the resin member 1a by rotating the resin member 2a to the state shown in FIG. 24C. it can.

After that, the mold 7 is moved along the guide 501 in the X51 direction (FIG. 17) toward the rotary mold 6a (and the frame 11) to close the mold 7 and the rotary mold 6a. At this time, it is assumed that the mold 7 is provided with a recess capable of accommodating the piece mold 32a moved to the position shown in FIG. 24 (c). 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, the piece mold 32a holding the resin member 2a and the piece mold 31a holding the resin member 1a are overlapped with each other, and then the mold 7 and the rotary mold 6a are closed. As a result, the mold 7 presses the piece mold 32a. As a result, the facing surfaces 1b and 2b of the resin member 1a and the resin member 2a are brought into close contact with each other. Next, as shown in FIG. 25 (b), the resin member is formed by filling the cavity 81d (FIG. 25 (a)) formed by the resin member 1a, the resin member 2a, and the piece mold 32a with the joining member 4. The 1a and the resin member 2a are joined.

An injection unit 9 arranged in the mold 7 is used to fill 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 side of the frame 11a. Further, instead of filling the joining member 4, a step of assembling by mutual fitting or engagement (for example, a click stop structure) of the resin member 1a and the resin member 2a may be adopted as described in the first embodiment.

As described above, also in the present embodiment, the resin members 1a and 2a constituting the parts 200a can be removed from the first molding portion 31 (31a) arranged side by side on the same mold surface and from the mold surface. Injection molding is performed in the same molding step by the second molding portion 32 (32a). Therefore, the resin members 1a and 2a can be injection-molded with extremely high accuracy. Further, in the present embodiment, the second molding portion 32 (32a) is removed from the mold surface by the driving means 100a and 100b (reversing moving device), and is inverted and moved with respect to the mold surface of the rotary mold 6a. , The second molding portion 32 (32a) is opposed to the first molding portion 31 (31a). Then, the mold 7 and the rotary mold 6 are molded, the joining member 4 is filled, and the resin member 2a and the resin member 1a are joined. As described above, also in this embodiment, the resin members 1a and 2a are assembled on one mold surface of the rotary mold 6a while being held by the holding portion of the rotary mold 6a, so that high-precision assembly is possible. realizable. Therefore, the component 200a can be manufactured with high accuracy.

Next, the fourth step will be described with reference to FIGS. 20, 23, 24, and 27. The fourth step corresponds to a step of releasing the piece mold 32a from the resin member 2a (part 200a). 27 (a) and 27 (b) show how the piece mold 32a and the resin member 2a are released from each other in the same manner as in FIG. 11 of the first embodiment.

First, the mold 7 and the rotary 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. 24 (c), (b), and (a), the piece mold 32a is again inverted and moved in the opposite direction by the driving means 100a and 100b, and the state of FIG. 24 (c) is shown. It returns 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 part 200a held by the piece mold 31a.

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

At this time, the resin member 2a has already been joined to the resin member 1a 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 of the rotary mold 6a (molding surface 30a). Or return to 30b). After that, the driving means 100a and 100b are separated from the upper and lower ends of the piece mold 32a by the operation in the order of FIGS. 23 (c) and 23 (b), that is, in the direction opposite to the above.

Next, the fifth step will be described with reference to FIGS. 13, 28 to 29. This fifth step corresponds to a step of releasing and taking out the part 200a. FIG. 28 shows the side surface (from the left side of FIG. 17) of the molding assembly device with the resin members 1a and 2a released from the rotary mold 6a. Further, FIG. 29 shows a state in which molding and assembling 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 part 200a is released from the mold by the ejector pin 101b built in the rotary mold 6a and taken out from the molding assembly apparatus. The drive source of the ejector pin 101b may be arranged in the rotating mold 6a or may be arranged on the frame 11 side. As described above, the production 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 first molding portion (31a) and a second molding portion (removable from the mold surface) are formed on a plurality of mold surfaces (molding surfaces 30a and 30b) of the rotary mold 6a. The same structure provided with 32a) is arranged. In the second embodiment, the molding surfaces 30a and 30b constitute the opposite mold surfaces of the rotating mold 6a having a substantially quadrangular prism shape. Therefore, in the present embodiment, as shown in FIG. 29, the rotating mold 6a and the frame 11, the mold 7 and the mold 5a are closed, and at the first process position 150a, the resin members 1d and 2d are used. Can be injection molded. At the same time, at the second process position 150b, the second molding portion 32 (piece mold 32a) can be inverted and moved to assemble the resin member 1a and the resin member 2b.

That is, according to the rotary mold structure of the second embodiment, the manufacturing process can be sequentially and simultaneously advanced by two (or more) molding surfaces having the same shape, and the molding assembly apparatus can be manufactured. Efficiency can be significantly improved. Moreover, since the resin members 1a and 2a, which are injection-molded using the molding portions (piece molds 31a and 32a) arranged side by side on the same mold surface and are limited in combination, can be combined, high-precision assembly can be realized. High quality parts 200a can be manufactured.

<Modification example>
In the second embodiment described above, the rotary mold 6a is provided with two different molding surfaces (30a, 30b) having the same configuration. However, depending on the number of steps of the parts to be manufactured, the rotary mold 6a may be used. The number of molding surfaces (30a ...) To be arranged may be any number. Further, for example, injection molding and assembly may be performed using only three mold surfaces out of the four surfaces of the tetragonal columnar rotary mold 6a. Further, although the mechanism for opening and closing the mold may be complicated, the entire rotary mold 6a may have the same molding surface on n side surfaces, for example, an n-square columnar shape. .. With such a configuration, the manufacturing process can be sequentially and simultaneously advanced by the n molding surfaces having the same shape, and the manufacturing efficiency of the molding assembly apparatus can be remarkably improved.

Further, as a reversing moving device for the second molding portion (32 or piece mold 32a) that can be removed from the mold surface, in the first and second embodiments, the driving means 10a and 10b having a U-shaped groove as a guide, 100a, 100b and the like are shown (FIGS. 10 and 24). However, in this reversing moving device, one of the molded portions is removed so that the resin members 1 (1a) and 2 (2a) that are molded and held by the two molded portions face each other, and the molding portion is removed from the mold surface. Any configuration may be used as long as it can be inverted and moved. Further, in the above two embodiments, the second molding portion that can be removed from the mold surface is the molding portion 32 or the piece mold 32a, but this is for convenience only. Of course, even if the side of the molding portion 31 or the piece mold 31a is inverted and moved by the reversing moving device instead of the molding portion 32 or the piece mold 32a, the functionally equivalent or equivalent manufacturing process can be executed. ..

Further, the form of trajectory and posture change when one of the first and second molding portions (piece molds) juxtaposed on the same mold surface is inverted and moved with respect to the mold surface by the reversing moving device can be determined. It does not have to be a shape defined by the U-shaped guide described above. 30 and 31 show an example of a form of change in trajectory and posture when one of the molded portions, for example, the second molded portion (piece mold 320) is inverted and moved. Although FIGS. 30 and 31 show the functional structure of the reversing moving device and do not show the specific structure of the reversing moving device, the trajectory and posture change of the molded portion as shown in both figures can be seen. As long as the structure can be realized, the detailed structure of the reversing moving device does not matter.

In FIGS. 30 (a), 30 (b), 31 (a), and 31 (b), the piece mold 310 and the piece mold 320 are the first molding portion (31 or the piece mold 31a) and the first Corresponds to each of the molding portions (32 or piece type 32a) of 2. The piece mold 310 and the piece mold 320 are juxtaposed on the same mold surface (not shown), while, for example, in this example, the piece mold 320 is removable from the same mold surface and can be inverted and moved. It includes a rotating shaft 900 to be used. The rotary shaft 900 is coupled to a rotary drive means (electric motor, speed reducer, etc.) (not shown), and by rotating the rotary shaft 900, the piece type 320 is turned inside out by 180 ° from the initial state shown in FIG. 30 (a). Can be reversed to the posture of.

The piece mold 310 and the piece mold 320 face each other with a mold pair (not shown), are molded, and the resin members 1aa and 2aa corresponding to the above-mentioned resin members 1 (1a) and 2 (2a) are molded by injection molding. To do. In FIGS. 30A and 30B, the resin members 1aa and 2aa correspond to the states 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 type 320. The guide 800 shown by a two-dot chain line in the figure has a U-shape and engages with the rotation shaft 900 of the piece shape 320 to determine a trajectory for reversing and moving the piece shape 320. As shown in the figure, the portion corresponding to the two U-shaped arms of the guide 800 passes through the center of the piece shape 310 and the center of the piece shape 320 at the initial position indicated by the alternate long and short dash line. The guide 800 is formed, for example, on the substrate of the drive means 10a and 10b (or 100a, 100b) constituting the above-mentioned reversing moving device. The drive means 10a and 10b (or 100a, 100b) also have a drive means (electric motor and speed reducer, cam mechanism or chain mechanism) (not shown) for moving the rotation shaft 900 of the piece type 320 along the guide 800. Etc.) shall be provided. The mechanism for moving the piece molds 310 and 320 shall be arranged at any part of the molding and assembling apparatus, such as at any position inside or outside the mold (not shown) holding the piece molds 310 and 320. Can be done.

In the above configuration, first, as shown in FIG. 30A, the resin member 1aa is injection-molded on the piece mold 310 and the resin member 2aa is injection-molded on the piece mold 320. Subsequently, as shown in FIG. 30B, the piece type 320 holding the resin member 2aa is moved in the X200 direction along the movement guide 800. Subsequently, as shown in FIG. 31A, at an appropriate position sufficiently separated from the mold surface (not shown) in which the piece mold 320 was held, the piece mold 320 was placed 180 in the Re direction about the rotation axis 900. °, flip. In this example, the rotating shaft 900 is provided on the piece type 320 in this embodiment, but the rotating shaft 900 may be installed outside the piece type 320.

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

Further, for example, the parts 200 and 200a shown in FIGS. 1 and 13 of the first and second embodiments are cleaning units used for, for example, a cartridge of an image forming apparatus. 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 moving device of the molding portion (piece mold). Such a manufacturing process is significantly different from the conventional method of assembling parts formed by cavities existing on different mold surfaces in a random combination in a subsequent process by using ultrasonic welding or the like. That is, in the above embodiment, when assembling one part, the joining partner is limited to the resin member formed on the same mold surface, so that high-precision assembly can be performed.

Further, the parts manufactured by the molding assembly apparatus adopting the present invention are not limited to the 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 constituting the developer unit used in the cartridge of the image forming apparatus having the shape as shown in FIG. 32 can also be manufactured by the same manufacturing process as described above. The component 201a in FIG. 32 is composed of resin members 201 and 202 as developing components. According to the same configuration as those of the first and second embodiments, the resin members 201 and 202 can be injection-molded at the same time on the molding portions (piece molds) juxtaposed on the same mold surface. Therefore, the component 201a can be assembled from the resin members 201 and 202, which are molded in the same process and have a limited number of combinations to be joined, with high accuracy.

Further, 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 the frame 11e which is a vertical (vertical) axis. Is. FIG. 33B corresponds to the top view of FIG. 33A, but in this configuration, the rotation shaft 90e is rotated in the Re direction to rotate the rotary mold 6e as shown in the figure. ..

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 tilted at an angle. For example, FIGS. 34 (a) and 34 (b) are the same drawings as those of FIGS. 33 (a) and 33 (b), but as shown in the figure, a rotating shaft that supports the rotating mold 6f with respect to the frame 11f. 90f may be arranged. In the configurations of FIGS. 34 (a) and 34 (b), the rotating shaft 90f that supports the rotating mold 6f with respect to the frame 11f is arranged along the YG direction (perpendicular to the vertical axis, that is, the horizontal direction). .. Then, in this configuration, as shown in FIG. 34 (b), the rotating shaft 90f is rotated in the Rf direction, and the rotating mold 6f is rotated. According to such a configuration, for example, by setting the lower positions in FIGS. 34 (a) and 34 (b) as the process positions for releasing and removing the parts, the mold release and removal steps of the manufactured parts can be performed. It may be possible to proceed well.

Further, for example, the size of the rotary mold 6e shown in FIGS. 33 (a) and 33 (b) is increased, and the above-mentioned first and second molded portions are not limited to one set, but a plurality of sets and the rotary mold 6e. It may be arranged on one mold surface of. In that case, a reversing moving device for reversing and moving the second molded portion is arranged for each set. With such a configuration, for example, two sets of parts (or a larger number of sets) can be taken, and the manufacturing efficiency of the molding assembly 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 can be considered. FIGS. 35 (a) and 35 (b) show the configuration of a molding assembly apparatus in which two rotating dies 6g1 and 6g2 are arranged. The rotating dies 6g1 and 6g2 are configured to rotate in the Rg1 and Rg2 directions around the rotating shafts 90g1 and 90g2, respectively, and each rotating die has a configuration similar to that shown in FIGS. 14 to 29, for example. Can be placed. Even with such a configuration, the manufacturing efficiency of the parts of the molding assembly apparatus can be remarkably improved.

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

Since it can be assembled, high-precision assembly can be realized. Therefore, the component 200 (200a) can be manufactured with high accuracy.

FIG. 38 shows an outline of a control procedure relating to the manufacture of the part 200a by the molding assembly device using the rotary mold 6a of the second embodiment executed by the control device of FIG. 36. The illustrated procedure can be stored as a control program of the CPU 601 in the above-mentioned storage means, for example, ROM 602. In the following, for example, a plurality of molding surfaces 30a and 30b (...) arranged on the rotary mold 6a are considered to be the first surface and the second surface (...), respectively, and the general expression thereof is "nth surface". Use expressions like. Similarly, as the general expression of the first, second ... process positions 150a, 150b (...), "m first process position" is used. In FIG. 38, for the sake of simplification, the manufacturing process for the molded surface of the nth surface (up to parts removal) is shown, but the same applies to the manufacturing process for the n + 1 surface and the n + 2 surface (...). Can be advanced at the same time.

In step S11 of FIG. 38, the CPU 601 rotates the rotary mold 6a (90 ° in the arrangement shown in FIG. 20) by the drive unit 12 of the drive device 611 (drive system), and the molding surfaces 30a, 30b ... The n-plane is moved to the m-th process position. As is clear from the above-described configuration of the rotary mold 6a, due to the rotational operation of the rotary mold 6a, the n + 1 surface and the n + 2 surface (...) are simultaneously placed on the m + 1 process position and the m + 2 process position (...). ) (For example, FIG. 22).

In steps S12 to S13, the CPU 601 has a drive device 611 (drive system) of the molding assembly device and an injection molding device 612 (injection system) at the m-th process position with respect to the nth surface of the molding surface (30a, 30b ...). ) Is controlled to execute the m-th step. At this time, at the same time, the corresponding process position can be executed at the m + 1 process position, the m + 2 process position, and the m + 3 process position (...) with respect to the other molding surfaces.

Upon confirming that the mth step has been completed in step S13, the CPU 601 determines in step S14 whether or not all the steps for the nth surface have been completed. When all the steps for the nth surface are completed in step S14, in step S15, the component 200a has moved to the take-out position (150b in the above example), where the ejector pin (100) of the component Take out. On the other hand, if all the steps for the nth surface have not been completed in step S14, the CPU 601 advances the control data of the counter (or pointer or the like) that manages the process position in step S16 so as to point to the next step. (M = m + 1). After that, the control returns to step S11, and by repeating the above operation, the m + 1 step, the m + 2 step, and the m + 3 step (...) with respect to the molding surface (30a, 30b ...) Of the nth surface can be executed. it can.
