Description

Technical Field

[0001] The present disclosure relates to a method for manufacturing a mold member and a method for controlling a manufacturing apparatus.

Background Art

[0002] In recent years, when joining molded products provided by a molding method typified by injection molding, a method using molten resin has been adopted for the purpose of improving the reliability of joining, the joining strength, and suppressing the apparatus cost. Specifically, first, a plurality of single parts are molded by an injection molding machine. Then, once the mold is opened, the mold is moved so that the single parts face each other. In that state, the mold is closed again, and a space for joining is formed by combining the molded single parts. Then, molten resin is poured into this space to perform joining. By adopting this method, the joining process can be completed within a single injection molding machine. Further, by moving the mold so that the molded products formed on the mold face each other, an improvement in positional accuracy such as the relative position and parallelism of the parts can be expected. Furthermore, the clamping force of the injection molding machine can be utilized for pressing the parts together.

[0003] However, in the case of the above method, the process of forming the molded product and the process of flowing the molten resin cannot be carried out simultaneously. Therefore, by providing a rotatable intermediate mold, a molded product is formed by one mold and the first surface of the intermediate mold, and the molded product is left on the intermediate mold. By rotating the intermediate mold by 180 degrees, the molded product is moved to the second surface of the intermediate mold. And a method may be adopted in which molten resin is applied by the other mold and the second surface of the intermediate mold. Thereby, since each process can be advanced simultaneously and in parallel on both surfaces, productivity is improved. At this time, by moving the intermediate mold every 90 degrees, on the operation side and the counter-operation side of the molding machine, it is also conceivable to assemble parts on the mold using a supply device, insert other parts, or discharge articles.

[0004] Patent Document 1 discloses a technique related to a molded product in which a first component, a second component, and a third component are joined by a joining resin. Patent Document 2 discloses a technique in which the position of a mold moves relatively by a die slide.

Summary of the Invention

Problems to be Solved by the Invention

[0006] In Patent Document 1, the following steps are performed using a mold for manufacturing a molded product. That is, a primary molding step of molding a first component, a second component, and a third component, an assembling step of assembling the three components in the mold, and a secondary molding step of filling a joining resin into a joining shape portion formed between the assembled three components are performed. In the technique of Patent Document 1, two assembling operations are required to combine the three components into one in the assembling step.

[0007] Here, for example, if the position of the mold moves relatively by a die slide as described in Patent Document 2, each component can be easily assembled. However, if the number of components is large, the same number of slide mechanisms are required, resulting in a complex and large-scale mold.

[0008] In addition, in the case where there is an insert member, assembly by sliding cannot be performed. In this case, it is desirable to take out the molded product from the mold once using a robot or the like and then assemble it. At this time, a clearance is required between the components to be assembled and the components to be assembled, so play occurs between the assembled components. Since this play occurs between each of the components to be combined, the overall play increases as the number of assembly operations increases.

[0009] In Patent Document 1, the three parts stacked in the assembly process are placed in the secondary molding space by being clamped again in the secondary molding process and joined with a joining resin. However, due to the looseness between the assembled parts, the joining shape formed between the assembled parts may not be correctly formed, and there is a risk that the joining resin may leak. In addition, the three parts may not fit into the space during the clamping operation of the secondary molding process, and there is a risk that the molded product may be shaved or caught between the molds. Also, if the number of assembly operations is large, the time required for the assembly process increases, and the tact time is extended.

[0010] An object of the present disclosure is to suppress looseness of the entire assembled parts and shorten the tact time of the assembly process.

Means for Solving the Problems

[0011] A method for manufacturing a mold member according to an aspect of the present disclosure is a manufacturing method for manufacturing a mold member by molding at least three or more molded products using a mold having opposing first and second molds, and joining the molded products with a joining resin, the method including: a step of molding a first molded product and a second molded product that are molded so as to remain in the first mold, and a third molded product that is molded so as to remain in the second mold; a step of assembling the molded second molded product to the molded first molded product; a step of moving at least one of the first mold and the second mold so that the first molded product with the second molded product assembled thereto remaining in the first mold and the third molded product remaining in the second mold face each other; and a step of joining by forming a joining shape portion by combining the first molded product with the second molded product assembled thereto and the third molded product, and pouring the joining resin into the joining shape portion.

Effects of the Invention

[0012] According to the present disclosure, it is possible to suppress the rattling of the entire assembled component and shorten the tact time of the assembly process.

Modes for Carrying Out the Invention

[0014] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. It should be noted that the following embodiments do not limit the matters of the present disclosure, and not all combinations of the features described in the following embodiments are essential for the solution means of the present disclosure. The same reference numerals are assigned to the same components. Also, the relative arrangement, shape, etc. of the components described in the embodiments are merely examples, and are not intended to limit the scope of this disclosure only to them.

[0015] <<First Embodiment>> FIG. 1 is a view showing a joint component according to the present embodiment. The joint component has a configuration in which a first molded product 1, a second molded product 2, and a third molded product 3 are joined by a joining resin 4. At the time of joining, a dissimilar member (insert member) such as a rubber part or a filter may be inserted between the molded products. In the example of FIG. 1, an example in which an elastic member 5 is inserted as the insert member is shown.

[0016] FIG. 2 is a view showing a state immediately before joining three components of a first molded product 1, a second molded product 2, and a third molded product 3 with a joining resin. FIG. 2 is not a view of an aspect according to the present embodiment, but a view of a comparative example for explanation. In FIG. 2, the first molded product 1 remains in the mold 6. In this mold 6, other parts are assembled to the first molded product 1. As described above, a clearance is required for assembly, so there is a risk that the parts may be displaced or tilted by the amount of the clearance. The more parts to be assembled, the greater the clearance generated between the respective parts, and thus the overall displacement becomes larger. In this state, the parts are configured to fit by being clamped in the space for joining with the joining resin 4. However, if the displacement is too large, the molded product may not fit into the space and may be sandwiched by the mold 6. Further, in the configuration of FIG. 2, joining is performed while compressing the inserted elastic member 5 by clamping. In this case, when assembling the second molded product 2, the second molded product 2 floats due to the reaction force of the rubber, so the mating portion with the first molded product assembled by clamping cannot be aligned to the deepest part. Since the mating portion is usually provided with a taper for easy assembly, the clearance becomes larger and the displacement and tilt also become larger due to the inability to align the mating portion to the deepest part.

[0017] FIG. 3 is a schematic view of a three-plate mold having a first mold 11 attached to the first platen 9 of a molding machine, a second mold 12 attached to the second platen of the molding machine, and an intermediate mold 13 therebetween, with the intermediate mold 13 rotating. In FIG. 3, the X direction is the mold opening / closing direction. The intermediate mold 13 is configured to be rotatable 360 degrees about an axis (an axis extending in the Z direction) orthogonal to the mold opening / closing direction. By attaching the intermediate mold 13 to the LM (Linear Motion) guide 14 of the second platen 10 of the molding machine, positioning during mold clamping becomes easy. In this mold, primary molding of a primary molded product is performed between the first mold 11 and the intermediate mold 13, and between the second mold 12 and the intermediate mold 13, respectively. Further, the intermediate mold 13 is rotated to perform secondary molding in which the primary molded products are joined with a joining resin between the second mold 12 and the intermediate mold 13.

[0018] Hereinafter, an example of a manufacturing method for manufacturing a mold member using a manufacturing apparatus including such a mold will be described. The mold member refers to a member manufactured using a mold.

[0019] Figures 4, 5, and 6 are diagrams for explaining the manufacturing process in this embodiment. Figures 4 to 6 are schematic views of the mold (manufacturing apparatus) in Figure 3 as seen from above. As a first step in this embodiment, a step of molding a molded product, that is, primary molding is performed. In the first step, as shown in Figure 4(a), in the space formed between the first mold 11 and the intermediate mold 13, the first molded product 1 and the second molded product 2 are molded by the first injection unit 7. At this time, as shown in Figure 4(a), using a part of the space for secondary molding with the bonding resin 4 formed between the second mold 12 and the intermediate mold 13, the third molded product 3 is also molded. After molding, as shown in Figure 4(b), the second mold 12 and the intermediate mold 13 move in the -X direction respectively, so that the molds are separated. In this embodiment, as shown in Figure 3, the second plate 10 of the molding machine provided with the second mold 12 and the intermediate mold 13 are movable molds. For this reason, the second mold 12 and the intermediate mold 13 are configured to be able to move in conjunction in the mold opening and closing direction (X direction). After molding, as shown in Figure 4(b), the first molded product 1 and the second molded product 2 are left on the intermediate mold side (intermediate mold 13), and the third molded product 3 is left on the second mold side (second mold 12).

[0020] As a second step in this embodiment, a step of assembling the molded products is performed. In the second step, as shown in Figure 5, the intermediate mold rotates 90 degrees. A robot 15 such as a 6-axis robot is prepared at a position facing the position where the first molded product 1 and the second molded product 2 have rotated 90 degrees. As shown in Figure 5, using this robot 15, the second molded product 2 is assembled to the first molded product 1 left on the intermediate mold 13 in the first step. At this time, the insertion of different members such as the elastic member 5 and the filter is also performed. As described above, in the first step, the third molded product 3 is molded using the space for secondary molding. For this reason, the number of times of assembling the parts is reduced by one compared to the case where all three parts are molded between the first mold 11 and the intermediate mold 13. Thereby, the total amount of displacement of the assembled parts generated in the second step can be reduced.

[0021] As the third step of this embodiment, a step of joining three parts, that is, secondary molding is performed. In the third step, as shown in FIG. 6, the intermediate mold further rotates 90 degrees from the state of FIG. 5. By this rotational movement, the space part holding the third molded product 3 molded in the first step faces the first molded product 1 to which the second molded product 2 is assembled. Then, as shown in FIG. 6, the second mold 12 (the second plate 10 of the molding machine) moves in the direction of closing the mold (+X direction). By this mold clamping operation, the three parts are assembled in the space part, and the joining resin 4, which is a molten resin, is poured into the joining shape parts formed on the three parts, thereby joining the three parts.

[0022] FIG. 7 is a view showing how three parts are assembled in the space part for secondary molding. The side surface of the second molded product 2 is not held by the mold. The first molded product 1, the second molded product 2, and the third molded product 3 have mating parts that mate when assembled. By the mold clamping operation, the position of the second molded product 2 is determined and joined with the first molded product 1 and the third molded product 3 while correcting the displacement and inclination of the second molded product 2 with the mating parts.

[0023] After being molded in the first step, the third molded product 3 is held in the space part for secondary molding without being taken out of the mold (the second mold 12) until the third step. For this reason, as shown in FIG. 7, there is no inclination or displacement in the third molded product 3, and the third molded product 3 is assembled with the first molded product 1 and the second molded product 2.

[0024] Also, in the example shown in FIG. 6, the second mold 12, that is, the second platen 10 of the molding machine, moves in the +X direction, so that the intermediate mold 13 also moves in the +X direction and mold clamping is performed. The intermediate mold 13 is also mounted on the second platen 10 of the molding machine, and both the second mold 12 and the intermediate mold 13 are movable units. Therefore, they cannot receive the mold clamping force and need to be pressed against the first mold 11 (the first platen 9 of the molding machine) side. For this reason, both the second mold 12 and the intermediate mold 13 are moving in the +X direction. However, it is not limited to this example. Based on the intermediate mold 13, the first mold 11 and the second mold 12 may be configured to be movable. In this case, if the first mold 11 and the second mold 12 can move independently, in the assembling process shown in FIG. 6, only the second mold 12 may move.

[0025] FIG. 8 is a schematic diagram of the entire liquid ejection device 16. FIG. 9 is a diagram for explaining the connection portion 21 of the liquid storage container 18. FIG. 10 is a diagram showing the joining parts used for the connection portion 21 of the liquid storage container 18. Hereinafter, a specific example of using the injection molding machine (manufacturing device) of the present embodiment in the liquid storage container 18 of the liquid ejection device 16 will be described with reference to FIGS. 8 to 10. Note that the liquid ejection device 16 of the present embodiment is an inkjet printer.

[0026] As shown in FIG. 8, the liquid ejection device 16 includes a liquid ejection head 17, a liquid storage container 18, a tube 19, and a hollow needle 20. Note that the example shown in FIG. 8 is a schematic diagram for explaining the outline, and it may have configurations other than these. The liquid ejection head 17 may be a line type liquid ejection head that performs continuous recording in one pass while continuously or intermittently conveying a plurality of recording media. Alternatively, it may be a serial type liquid ejection head that performs recording by repeating the conveyance of the recording medium and the reciprocating scanning of the liquid ejection head 17. The liquid ejection device 16 may include a liquid storage container 18 of K (black) single color, or may include liquid storage containers 18 corresponding to each color so that full-color printing using CMYK (cyan, magenta, yellow, black) inks is possible.

[0027] The liquid storage container 18 for storing liquid and the liquid ejection head 17 communicate with each other via a tube 19 and a hollow needle 20. The liquid stored in the liquid storage container 18 is supplied to the liquid ejection head 17 through the hollow needle 20 and the tube 19.

[0028] When manufacturing the connection part 21 of the liquid storage container 18 as shown in FIG. 8, etc., the connection part 21 is formed as a joined part made of a joining resin. FIG. 9(a) is a perspective view of the liquid storage container 18. FIG. 9(b) is an exploded perspective view of the part of the connection part 21 in the liquid storage container 18. FIG. 9(c) is a cross-sectional view of the state where the hollow needle 20 is inserted into the connection part 21, that is, the state where the liquid storage container 18 is attached to the liquid ejection device 16. As shown in FIG. 9, in the connection part 21, the hollow needle 20 is inserted into the elastic member 5 having a cut. By adopting such a configuration, the connection part 21 can provide the function of a valve that enables the retention and supply of liquid. As shown in FIGS. 9(b) and 9(c), the connection part 21 is a joined part including a first molded product 1, a second molded product 2, a third molded product 3, and an elastic member 5.

[0029] FIG. 10 is a view showing the joined part as the connection part 21. As shown in FIG. 10(a), the first molded product 1, the second molded product 2, and the third molded product 3 are formed by injection molding. Next, as shown in FIG. 10(b), the elastic member 5 is supplied to the first molded product 1. Then, as shown in FIG. 10(c), the second molded product 2 and the third molded product 3 are assembled and joined to the first molded product 1 to which the elastic member 5 has been supplied. The joining can be performed by pouring the joining resin 4 into the space part formed between the molded products to form an integral molded product, similar to the joined part shown in FIG. 1. In the injection molding machine device in the present embodiment, in addition to the molding of the first molded product 1 and the second molded product 2, the third molded product 3 is molded using a part of the space part for performing secondary molding.

[0030] As described above, according to the present embodiment, it is possible to suppress the rattling of the entire assembled parts and shorten the tact time of the assembly process. Specifically, in the joining parts that join molded parts of three or more parts where the assembly work occurs two or more times in the assembly process, while reducing the number of assembly times in the assembly process, a plurality of parts can be assembled into one in the secondary molding process. By reducing the number of assembly times, the assembly itself becomes easier, and the rattling of the entire assembled parts can also be reduced. In addition, the primary molded product formed in the secondary molding space part is joined without being taken out of the mold. That is, since the position of the primary molded product formed in the secondary molding space part is determined by the mold, rattling does not occur. Also, by reducing the number of assembly times, the tact time of the assembly process can be shortened.

[0031] In addition, in the above example, the process for one part was described, but it is also possible to continuously manufacture a plurality of parts. That is, in the state of FIG. 6, by using the first mold 11 and the intermediate mold 13 to mold the next part corresponding to FIG. 4(a), it is also possible to continuously produce the joining parts.

[0032] Also, as described in the present embodiment, by using the rotating intermediate mold 13, each process can be dispersed on different surfaces, so the space efficiency is improved. In addition, since the work can be performed simultaneously and in parallel on each surface, the production capacity can be improved.

[0033] <<Second Embodiment>> In the first embodiment, an example of performing the primary molding process, the assembly process, and the secondary molding process using the first mold 11, the second mold 12, and the intermediate mold 13 was described. In this embodiment, an example of performing the primary molding process, the assembly process, and the secondary molding process without using the intermediate mold will be described. In this embodiment, it is assumed that either the first board 9 of the molding machine equipped with the first mold 11 or the second board 10 of the molding machine equipped with the second mold 12 is a movable board.

[0034] FIG. 11, FIG. 12, and FIG. 13 are diagrams for explaining the manufacturing process in the present embodiment. FIG. 11, FIG. 12, and FIG. 13 are schematic diagrams of scenes corresponding to FIGS. 4, 5, and 6, respectively. In the present embodiment, the second mold 12 has a slidable slide mechanism 121.

[0035] As a first step, a step of molding a molded product, that is, primary molding is performed. In the first step, as shown in FIG. 11(a), in the space formed in the first mold 11, the first injection unit 7 molds the first molded product 1 and the second molded product 2. At this time, as shown in FIG. 11(a), the third molded product 3 is also molded using a part of the space for secondary molding formed by the bonding resin 4 in the second mold 12. After molding, as shown in FIG. 11(b), when the second mold 12 moves in the -X direction, the molds are separated. After molding, as shown in FIG. 11(b), the first molded product 1 and the second molded product 2 remain in the first mold 11, and the third molded product 3 remains in the second mold 12.

[0036] As a second step, a step of assembling the molded products is performed. In the second step, as shown in FIG. 12, with the molds open, the robot 15 enters between the molds for assembly. As described in the first embodiment, insert members such as the elastic member 5 are also assembled at this time. Also, as shown in FIG. 12, when the slide mechanism 121 moves, the third molded product 3 moves to a position facing the first molded product 1 and the second molded product 2.

[0037] As described above, in the first step, the third molded product 3 is molded using the space for secondary molding. Therefore, the number of times of assembling the parts is reduced by one compared to the case where all three parts are molded in the first mold 11. As a result, the total amount of displacement of the assembled parts generated in the second step can be reduced.

[0038] As a third step, a step of joining three components is performed, that is, secondary molding is carried out. In the third step, as shown in FIG. 13, from the state of FIG. 12, the second mold 12 moves and mold clamping is performed. By this mold clamping operation, the three components are assembled in the space portion, and by pouring the bonding resin 4 into the bonding shape portions formed on the three components, the three components are joined.

[0039] As described above, even in the present embodiment that does not use an intermediate mold, it is possible to suppress the rattling of the entire assembled components and shorten the tact time of the assembly process.

[0040] <<Other Embodiments>> In the examples described in the first embodiment and the second embodiment, the form in which the first mold 11 does not move has been described. However, in the first embodiment and the second embodiment, the first mold 11 may also be in a form that moves. Alternatively, a form in which the first mold 11 moves and the second mold 12 and the intermediate mold 13 do not move may be used. That is, in the first embodiment, at least one of the first mold 11, the second mold 12, and the intermediate mold 13 may be configured to be movable. In the second embodiment, at least one of the first mold 11 and the second mold 12 may be configured to be movable.

[0041] Also, in the first embodiment and the second embodiment, a method for manufacturing a mold member using a manufacturing apparatus for the mold member has been described. The examples described in the first embodiment and the second embodiment are also control methods for the manufacturing apparatus for the mold member. Each of the above-described steps is performed by control by a control unit (not shown) or the like.
