Abstract
Description
[Technical Field]
[0001] The present disclosure relates to a chuck jig for transporting a laminate, a receiving jig, a preform mold, an insert molding mold, and a method for transporting a laminate. [Background technology]
[0002] In recent years, the diversification of customer preferences has led to a growing need for decorative techniques that offer a wide range of design expressions and high-quality design for exterior parts of home appliances, interior parts for automobiles, etc. One such decorative technique is the insert molding method, in which decorative material is positioned and fixed in an injection mold and integrated with the injected resin. This insert molding method makes it possible to obtain molded products using decorative material made from sheets, such as thinly sliced wood veneer or decorative film printed on a thick substrate.
[0003] On the other hand, when insert molding these sheet-formed decorative materials, it is common to need a mechanism for fixing the decorative material to the injection molding die, such as drilling positioning holes in the margins around the outer periphery of the product in the decorative material and providing pins for setting the positioning holes in the injection molding die (see, for example, Patent Document 1). Note that insert molding as defined in this disclosure refers to a method of forming the entire exterior surface of a product with decorative material, and also includes shapes in which the decorative material wraps around from the exterior surface to the backside of the product, depending on the product specifications. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Patent Application Publication No. 8-267505 Summary of the Invention [Problem to be solved by the invention]
[0005] Figure 7 is a perspective view showing an insert film used in the manufacturing method of an insert-molded product disclosed in Patent Document 1. In Figure 7, an insert film 35 having holes 34 in attachment pieces 33 is inserted into a recessed mold 37 having pins 36 to prevent misalignment within the mold. In this case, if the film 35 has a certain degree of rigidity, the insert film 35 can be fixed to the recessed mold 37 with just two holes 34 and pins 36, as shown in Figure 7.
[0006] However, when placing a flexible material such as cloth in a recessed mold, fixing it in only one place on each of the two sides as shown in Figure 7 will cause the holes and the left and right edges to sag, and is not effective in preventing misalignment. In other words, it is necessary to install pins in multiple places to match the product shape, more than the two places shown in Figure 7. However, the more pins and holes there are, the more time it takes to attach them to the mold. When placing a flexible material such as cloth with holes in it in a recessed mold, depending on the person, it takes more time depending on the number of holes and pins, which is disadvantageous from the perspective of productivity.
[0007] Therefore, an object of the present disclosure is to provide a chuck jig that can easily transport a laminate with low rigidity. [Means for solving the problem]

[0032] Hereinafter, a chuck jig for transporting a laminate, a receiving jig, a preform molding die, an insert molding die, and a laminate transport method according to each embodiment of the present disclosure will be described with reference to the accompanying drawings.
[0033] (Embodiment 1) <Decorative parts> FIG. 1 is a schematic cross-sectional view showing the cross-sectional structure of a decorated part 6 using a laminate 7 transported by a chuck jig for transporting a laminate according to the present disclosure. As shown in FIG. 1, the decorated part 6 is made up of a base resin 5 and a laminate 7 , and the laminate 7 is further made up of a decorative layer 2 , an adhesive layer 3 and a support layer 4 .
[0034] <Decorative layer> The decorative layer 2 is not limited as long as it is made of a commonly used decorative material such as fabric, natural wood, leather, or decorative film. The thickness of the decorative layer 2 is not particularly limited depending on the characteristics of the decorative material, but is preferably in the range of 0.1 mm to 3 mm. If the thickness of the decorative layer 2 is less than 0.1 mm, handling becomes difficult, and defects such as wrinkles and tears are likely to occur during processing. On the other hand, if the thickness of the decorative layer 2 is greater than 3 mm, the hardness of the entire laminate increases, which reduces flexibility and reduces its ability to conform to the product shape.
[0035] <Adhesive layer> The adhesive layer 3 serves to bond the decorative layer 2 and the support layer 4. The adhesive layer 3 is composed of a resin such as a vinyl chloride-vinyl acetate copolymer, an olefin, a polyolefin, a urethane, or an acrylic resin, and is formed in a manner that completely covers the surface of the support layer 4. By covering it, an airtight seal is created between the decorative layer and the support layer, making it possible to use a vacuum during transportation and preventing liquids from wetting the support layer, thereby improving the durability of the industrial product. There are no restrictions on the material as long as it is possible to bond the decorative layer 2 and the support layer 4 to each other.
[0036] Furthermore, the average film thickness of the adhesive layer 3 is preferably 2 μm or more and 200 μm or less. By setting the thickness to 2 μm or more, sufficient film strength of the adhesive layer 3 itself can be obtained, and peeling defects such as cohesive failure can be suppressed. Furthermore, a sufficient adhesive thickness can be obtained, and sufficient adhesive strength to the decorative layer 2 and the support layer 4 can be obtained. On the other hand, by setting the thickness to 200 μm or less, it is possible to suppress increases in manufacturing costs due to increased film thickness while maintaining sufficient adhesive strength. Considering the balance between film strength, adhesive strength, and manufacturing costs, a film thickness of 3 μm or more and 100 μm or less is more preferable. Furthermore, the penetration film thickness of the adhesive layer 3 into the support layer 4 (due to the anchor effect) is preferably 5 μm or more. By setting the penetration film thickness of the adhesive layer 3 to 5 μm or more, sufficient adhesive strength to the support layer 3 can be obtained, and the occurrence of interfacial peeling defects can be suppressed. The process for forming the adhesive layer 3 is not limited, depending on the handling form.
[0037] When the adhesive layer 3 is used in a liquid state, it may be formed in advance on the decorative layer 2 side or on the support layer 4 side using a known printing or coating process such as spray atomization, roll coating, or inkjet coating. Alternatively, when the adhesive layer 3 is used in a solid state such as a sheet, it may be bonded to the decorative layer 2 first and then to the support layer 3. Alternatively, conversely, it may be bonded to the support layer 4 first and then to the decorative layer 2. Furthermore, the decorative layer 2, adhesive layer 3, and support layer 4 may be bonded simultaneously. By forming the adhesive layer 3 in a form that completely covers the surface of the support layer 4, it is possible to improve its conformability to the support layer 4.
[0038] <Support layer> The support layer 4 improves the strength of the laminate 7 itself through the heat press processing and plays a role in maintaining the predetermined processed shape of the laminate 7. The adhesive layer 3 is formed in a form that completely covers the support layer 4, and the decorative layer 2 is formed via the adhesive layer 3, so that the improvement in the strength of the support layer 3 itself effectively improves the strength and shape retention of the laminate 7 itself.
[0039] The material, thickness, etc. of the support layer 4 can be selected depending on the application. The support layer 4 is formed, for example, by forming a web by folding fibers spun from a carding machine diagonally across each other, and then entangling the fibers using a needle punch machine to form a nonwoven fabric sheet. Materials that can be selected include, for example, polyester, polyethylene terephthalate, polypropylene, rayon, nylon, and vinylon. The support layer 4 may be formed from two or more materials with different melting points, or from similar materials with different melting points. For example, if polyethylene terephthalate fibers are used, and polyethylene is coated with a lower melting point than polyethylene terephthalate, the polyethylene terephthalate fibers within the nonwoven fabric sheet can be impregnated with polyethylene by optional heat treatment after the nonwoven fabric sheet is formed, resulting in a support layer 4 with high strength.
[0040] <Thermocompression bonding process> 2 is a schematic cross-sectional view showing the thermocompression bonding process for obtaining the laminate 7. The laminate 7 is formed by compression bonding using a thermocompression bonding device P that can apply heat and pressure. By applying heat and pressure, the adhesive layer 3 disposed between the decorative layer 2 and the support layer 4 melts, and the decorative layer 2 and the support layer 4 are tightly adhered to each other, thereby obtaining the laminate 7. Examples of thermocompression bonding devices P include well-known devices such as a general-purpose press device that applies pressure with upper and lower heated plates, a multi-stage press device, a vacuum laminator device, and a roll-to-roll press device. The laminate 7 manufactured using these devices is in a stiffer sheet state than when the decorative layer 2 is used alone, which improves handling during subsequent processing. If the support layer 4 described above is made of two types of fibers, adjusting the temperature of the thermocompression bonding device melts one fiber and impregnates the other fiber, thereby increasing the strength of the laminate 7.
[0041] FIG. 3A is a plan view of the trimming process in which the laminate 7 is processed into a two-dimensional shape that takes into account the unevenness and bending of the product shape, and FIG. 3B is a cross-sectional view of FIG. 3A. Trimming methods include shape punching using a Thomson die, laser cutting, and hand cutting, and are not limited as long as they can be trimmed to the desired product shape. In subsequent processes, the laminate is processed into a three-dimensional shape that matches the product shape. Therefore, if trimming can be performed so that there is no excess material in the product shape, subsequent post-processing is unnecessary, improving productivity. For example, holes 17 may be formed to improve the positional accuracy of the end faces of the laminate 7 in the decorative part 6. The hole shape may be, for example, a circle, ellipse, square, cross, or the like.
[0042] <Preforming process> 4-1 to 4-7 are schematic cross-sectional views showing the cross-sectional shapes of the punch 12 and die 14 constituting the preform mold 40 in the preform process (shaping process) for forming (shaping) the laminate 7 into the product shape. The preform process (shaping process) using the holes 17 and positioning pins 18 provided in the laminate 7 and the preform mold 40, which is a feature of the present disclosure, will be described using FIGS. 4-1 to 4-7. For convenience, in the drawings, the vertical direction is designated as the Z direction, the right-hand direction on the paper is designated as the X direction, and the depth direction on the paper is designated as the Y direction.
[0043] FIG. 4-1 is a schematic cross-sectional view showing the initial state of the preforming process for the laminate 7. The preforming mold 40 includes a movable punch 12, a stripper 13, a stripper drive mechanism 9, a die 14, a pad 15 attached to the die 14, a pad drive mechanism 16, and a stripper drive mechanism 9. The pad drive mechanism 16 is installed to support and press the laminate 7 as the punch 12 moves. The pad drive mechanism 16 is fabricated using a known drive method, such as a metal spring, a gas spring, or a hydraulic or pneumatic pump, and is selected depending on the preforming process, such as the required pressure, cost, and control method. These drive mechanisms 9 and 16 each serve to drive the stripper 13 and the pad 15. Known drive methods, such as a metal spring, a gas spring, a hydraulic or pneumatic pump, are used, and are selected depending on the preforming process, such as the required pressure, cost, and control method.
[0044] The hole 17 provided in the laminate 7 and the positioning pin 18 passing through the hole 17, which are a feature of the present disclosure, may be disposed, for example, in the die 14 or pad 15 as shown in FIG. 4-1 . The punch 12 has a hole corresponding to the positioning pin 18. If the tip of the positioning pin A18 is tapered, it acts as a guide when setting the laminate 7, making setting easier. Having two positions determines the geometric position of the laminate 7 and the die 14, but if the laminate 7 is flexible, sagging of the laminate 7 may occur. In response to this, by providing holes 17 provided in the laminate 7 and positioning pins 18 passing through the holes 17 at both ends of the die 14, it is possible to prevent the laminate 7 from sagging into the recessed portion of the die 14. However, to prevent the hole 17 from being torn by the positioning pin 18 when the laminate 7 is drawn into the die 14 in a process described later, a positioning pin drive mechanism A19 is required to extend and retract the positioning pin. The positioning pin drive mechanism A19 is manufactured using a known drive method such as a metal spring, gas spring, hydraulic or air pump, and is selected depending on the required pressure, cost, control method, etc. of the preforming process.
[0045] 4-2 is a schematic cross-sectional view showing a state in which the punch die 12, the stripper 13, and the stripper drive mechanism 9 are operating. The stripper 13 supports the laminate 7 along the pressure direction (Z direction), and also presses the laminate 7 along the pressure direction (Z direction). As a result, the stripper 13 restrains the laminate 7, and a laminate restraint point A20 is generated.
[0046] FIG. 4-3 is a schematic cross-sectional view showing the punch 12, stripper 13, and stripper drive mechanism 9 in operation. The punch 12 further descends, and the laminate 7 is held between the punch 12 and the pad 15, creating a laminate restraint point B21. Because of the presence of the laminate restraint point B21, the hole 17 formed in the laminate 7 at this position will not tear. Therefore, if a positioning pin 18 is placed within the range of the laminate restraint point B21, a positioning pin drive mechanism for pulling down the positioning pin is not required, and the mechanism of the die 14 does not become complicated.
[0047] 4-4 is a schematic cross-sectional view showing the operation of the punch 12, the stripper 13, and the stripper drive mechanism 9. The punch 12 further descends, the laminate 7 deforms along the punch 12, and the punch 12 deforms the laminate 7 from a two-dimensional shape to a three-dimensional shape.
[0048] 4-5 is a schematic cross-sectional view showing a state where the operation of the punch 12 has progressed. As a result, the laminate restraint point A20 disappears. This is because as the operation of the punch 12 progresses, the end face of the laminate 7 moves away from the upper surface, and the laminate 7 is pulled into between the punch 12 and the die 14.
[0049] 4-6 are schematic cross-sectional views showing a state in which punch 12 has been moved to the bottom dead center, whereby laminate 7 is shaped. 4-7 is a schematic cross-sectional view showing a state in which the punch die 12 has been returned to its initial state. This completes the preforming step, and the shaped laminate 7 can be taken out after the preforming step.
[0050] <Laminate conveying method> Fig. 5-1 is a schematic cross-sectional view showing the final step of the preforming process. Fig. 5-2 is a schematic cross-sectional view showing a receiving jig 22 that holds the preformed laminate 7. In Fig. 5-1, the pad 15 has a plurality of positioning pins 18. As shown in Figures 5-1 and 5-2, the shaped laminate 7 after the preforming step is held by a receiving jig 22 having a support surface corresponding to the unevenness of the shaped laminate 7. The laminate 7 removed from the preforming mold 40a may be transferred to the receiving jig 22 by hand, for example. Alternatively, as shown in a second embodiment described later, the laminate 7 may be transferred by a chuck jig without using a receiving jig.
[0051] <Receiving jig> The receiving jig 22 is a jig (fixture) for repeatedly setting the laminate 7 with high accuracy. The receiving jig 22 includes a support surface facing the surface of the laminate 7 and capable of supporting the laminate 7, a positioning pin B23, and a positioning pin drive mechanism 19. The receiving jig 22 may also include a suction groove 24 and a negative pressure generator 25. The shape of the support surface of the receiving jig 22 into which the laminate 7 is inserted is the same as the surface of the die 14 facing the surface of the laminate. The laminate is supported by the support surface corresponding to the surface of the laminate. The positioning pin B23 is a mechanism for efficiently aligning and inserting the laminate 7 into the die 14, and corresponds to and can be inserted into the hole 17 formed in the laminate 7. The positioning pin B23 protrudes from the support surface. Furthermore, if the tip of the positioning pin B23 is tapered, it serves as a guide when setting the laminate 7, making setting easier. One or more positioning pins B23 may be used. If there are a plurality of pieces, the positioning accuracy increases, but it takes time to insert the laminate 7 into the receiving jig 22.
[0052] The suction grooves 24 and negative pressure generator 25 are mechanisms for enhancing adhesion between the laminate 7 and the receiving jig 22. Depending on the shape of the preformed laminate 7, a gap may form between the laminate 7 and the receiving jig 22. At this location, the negative pressure generated by the negative pressure generator 25 via the suction grooves 24 can be used to reduce the gap. This contributes to improving the positioning accuracy of the laminate 7 relative to the receiving jig 22. Furthermore, if there is no gap between the laminate 7 and the receiving jig 22, it is possible to reduce the degree of misalignment between the laminate 7 and the receiving jig 22 due to vibrations at the production site. Two or more sets of suction grooves 24 and negative pressure generators 25 may be provided, as shown in Figure 5-2, depending on the shape and size. The negative pressure generator 25 is fabricated using a known method, such as a Combum type or vacuum pump, and is determined based on the required pressure, cost, and control method.
[0053] Fig. 5-3A is a schematic cross-sectional view showing a state in which the second pin of the chuck jig is coaxially connected to the first pin of the receiving jig. Fig. 5-3B is a schematic cross-sectional view showing a state in which the chuck jig 26 is lowered and the laminate 7 is handed over from the receiving jig 22. Fig. 5-3C is a schematic cross-sectional view showing a state in which the chuck jig 26 is raised and receives the laminate 7 from the receiving jig 22. In the drawings, for convenience, the vertical direction is shown as the Z direction, the right-hand direction of the paper is shown as the X direction, and the depth direction of the paper is shown as the Y direction. 5-3A to 5-3C, an operation method (transport method) of the chuck jig 26 that repeatedly receives the laminate 7 inserted into the receiving jig 22 from the receiving jig 22 with high accuracy, which is a feature of the present disclosure, will be described.
[0054] <Chuck jig> The chuck jig 26 includes a concave pin 27, a concave pin drive mechanism 28, and a soft pad 30. It may further include a negative pressure generator 25 and a suction bellows 29. The soft pad 30 has a support surface facing the surface of the laminate 7 and capable of supporting the laminate. The soft pad 30 may be made of a known material that deforms when pressure is applied, such as urethane or rubber. The concave pins 27 correspond to holes in the laminate 7 and protrude from the support surface. The surface of the suction bellows 29 that contacts the laminate 7 may be positioned to have the same area as the soft pad 30 or within a range of approximately 3 mm in front and behind it. The amount of deformation of the bellows should preferably be approximately 3 mm. The tip of the concave pin 27 does not have to be concave; it may also be convex. In this case, the tip of the positioning pin B of the receiving jig should be concave rather than convex.
[0055] In Fig. 5-3A, the negative pressure generator on the receiving jig 22 side is turned on, and the laminate 7 is inserted into the receiving jig 22 with high repeatability. The concave pin 27 is disposed coaxially opposite the positioning pin B23, and the soft pad 30 has a shape corresponding to the laminate 7 at that position. As shown in Fig. 5-3A, the concave pin 27 of the chuck jig 26 is connected coaxially with the positioning pin B23 of the receiving jig 22.
[0056] FIG. 5-3B is a schematic cross-sectional view showing the state in which the chucking jig 26 is lowered in the vertical direction (Z direction) and the laminate 7 is transferred from the receiving jig 22. The negative pressure generator 25 on the receiving jig 22 side is turned OFF, and when the positioning pin drive mechanism 19 retracts, the positioning pin B also retracts, and the concave pin 27 of the chucking jig 26, which is coaxially connected, penetrates the hole 17 provided in the laminate 7. The chucking jig 26 is lowered to an extent that the soft pad 30 is slightly deformed, thereby bringing the soft pad 30 and the laminate 7 into tight contact with each other without any gaps. After the chucking jig 26 is lowered and the concave pin 27 penetrates the hole 17 in the laminate 7, the negative pressure generator 25 provided on the chucking jig 26 is turned ON, creating a negative pressure between the suction bellows 29 and the laminate 7, further adhering them to each other. If both the positioning pin drive mechanism 19 and the concave pin drive mechanism 28 are springs, the spring factor of the positioning pin drive mechanism 19 must be set sufficiently lower than that of the concave pin drive mechanism 28. When pressing the soft pad 30 against the laminate 7 so as to slightly deform it, depending on the shape, the laminate 7 may slip relative to the receiving jig, but if the negative pressure generator 25 and the suction grooves 24 are arranged in the receiving jig 22 and the negative pressure is strong and the number of suction grooves 24 is increased, slippage is less likely to occur.
[0057] In FIG. 5-3C, as the chucking jig 26 rises, the laminate 7 separates from the receiving jig 22 and is fixed to the chucking jig 26. A plurality of suction bellows 29 may be provided on the chucking jig 26 depending on the shape, weight, and airtightness of the laminate 7. Similarly, a plurality of negative pressure devices 25 may be provided on the chucking jig 26. The ON / OFF timing of the negative pressure generating devices 25 provided on the receiving jig 22 and the chucking jig 26 may be automated using a timer, proximity sensor, physical switch, or the like. The chucking jig 26 may be held by a person or a robot.
[0058] <Transporting the laminate to the insert molding die> 5-4A to 5-4E illustrate an injection molding process in which the laminate 7 chucked by the chucking jig 26 is inserted into the cavity mold 10 of the insert molding die 50, and injection molding resin 8 is applied to obtain the decorated part 6. Note that the same members as those in Figs. 5-3A to 5-3C are designated by the same reference numerals, and their description will be omitted. Typically, injection molding machines used in injection molding processes are divided into vertical (vertical) types that open and close vertically (Z direction) and horizontal types that open and close horizontally (X direction). For decorative parts typically made of laminates such as film or fabric, horizontal injection molding machines are generally selected due to their product size. Therefore, Figures 5-4A to 5-4E illustrate the injection molding process using a horizontal injection molding machine. For convenience, the vertical direction is designated as the Z direction, the opening and closing direction between the cavity mold 10 and core mold 11 of the insert molding mold 50 is designated as the X direction, and the depth direction of the page is designated as the Y direction. When inserting fabric into the cavity mold 10 of a horizontal injection molding machine, the chuck jig 26 must be rotated 90 degrees as shown in Figure 5-4A compared to Figure 5-3A. However, the chuck jig 26 according to the present disclosure can also be applied to a vertical (upright) molding machine, as it simply eliminates the need for a 90-degree rotation.
[0059] FIG. 5-4A is a schematic cross-sectional view showing a state in which the concave pin (second pin) of the chuck jig 26 holding the laminate is coaxially connected to the positioning pin C of the cavity mold 10 of the insert molding die 50. FIG. 5-4A shows the state just before the chuck jig 26, which chucked the laminate 7 in FIG. 5-3C, is rotated 90 degrees and inserted into the cavity mold 10. The cavity mold 10 is provided with a suction groove 24, a negative pressure generator 25, and a positioning pin C31, similar to the receiving jig 22. As shown in FIG. 5-4A, the concave pin 27 of the chuck jig 26 is connected coaxially to the positioning pin C31 of the cavity mold 10.
[0060] FIG. 5-4B is a schematic cross-sectional view showing the state in which the chuck jig 26 is pressed into the cavity mold 10 and the laminate 7 is transferred from the chuck jig 26 to the cavity mold 10. In FIG. 5-4B, when the chuck jig 26 advances toward the cavity mold 10 and the laminate 7 comes into contact with the cavity mold 10, the negative pressure generator on the chuck jig side is turned OFF and the negative pressure generator 25 on the cavity mold 10 side is turned ON. Furthermore, the concave pin 27 on the chuck jig is retracted by the concave pin drive mechanism 28 relative to the positioning pin C31 coaxially connected to the cavity mold 10, so that the positioning pin C31 of the cavity mold 10 penetrates the laminate 7. As a result, the laminate 7 is transferred from the chuck jig 26 to the cavity mold 10.
[0061] Fig. 5-4C is a schematic cross-sectional view showing the state in which the chuck jig 26 has been removed from the cavity mold and the laminate has been transferred from the chuck jig to the cavity mold. As shown in Fig. 5-4C, the chuck jig 26 has been retracted from the cavity mold 10, and the laminate 7 is held by the positioning pin C31 of the cavity mold 10 and the negative pressure generator 25. As described with reference to Figs. 5-4B and 5-4C, a feature of the present disclosure is that the chuck jig 26 can transfer a soft laminate 7 such as a cloth into the cavity mold 10 in a single advance. In the conventional example, it was necessary to manually set the positioning pins of the cavity mold 10 one by one, equal to the number of holes provided in the laminate 7. In the case of a laminate 7 that is soft like cloth, multiple holes are required to fit it to the cavity mold, which takes time and reduces productivity. Furthermore, when the laminate 7 is manually set into the cavity mold 10, there is a possibility that quality stability will become an issue due to variations between operators.
[0062] In the case of transferring the laminate 7 according to the present disclosure, by using the chuck jig 26, it is expected that the repeatability of the transfer will be improved compared to at least manual methods, and that productivity will be improved by shortening the setting time.
[0063] 5-4D is a schematic cross-sectional view showing a process in which, with the core mold 11 and the cavity mold 10 closed, molten injection molding resin 8 is poured into the back surface of the laminate 7. This forms a decorated part 6 made up of the laminate 7 and the molding resin 8 on the back surface side. FIG. 5-4E is a schematic cross-sectional view showing that the decorated part 6 can be obtained by opening the core mold 11 and the cavity mold 10.
[0064] (Embodiment 2) The second embodiment relates to a transfer method for transferring the laminate 7 directly from the die A32 in the preforming process to the chuck jig 26 without using a receiving jig. A transfer method for transferring the laminate 7 from the die 14 to the chucking jig 26 in the preforming process will be described using Figures 6-1 to 6-3. The same reference numerals are used for the same components as in Figures 4-1 to 4-7 and Figures 5-1 to 5-4E, and their description will be omitted. In the second embodiment, the chucking jig 26 chucks the laminate 7 from the die A 32, so the positioning pin drive mechanism 19, suction groove 24, and negative pressure generator 25, which were installed on the receiving jig 22 in Figure 5-2, are provided on the die A 32. The chucking jig 26 in Figures 6-1 to 6-3 may be held by a person or a robot.
[0065] Fig. 6-1 is a schematic cross-sectional view showing a state in which a chuck jig 26 is placed on a die A32 in the preforming process. In Fig. 6-1, the laminate 7 formed in the preforming process is tightly placed on the die A32 by the suction grooves 24 with the negative pressure generator 25 in the ON state for generating negative pressure. The concave pin 27 of the chuck jig 26 is arranged coaxially with the positioning pin A18 provided on the pad 15. Note that there may be two or more pairs of positioning pin A18 and concave pin 27.
[0066] FIG. 6-2 is a schematic cross-sectional view showing the state in which the concave pins 27 of the chuck jig 26 are coaxially connected to the positioning pins A18 provided on the pads 15 of the die mold A32. In FIG. 6-2, the negative pressure generator 25 on the die mold A32 side is turned OFF, and the negative pressure generator 25 on the chuck jig 26 is turned ON. As a result, the positioning pins A18 arranged coaxially are retracted by the positioning pin drive mechanism 19, and the concave pins 27 are inserted into the holes 17 of the laminate 7. The chuck jig 26 is lowered to an extent that the soft pad 30 is slightly deformed, thereby bringing the soft pad 30 and the laminate 7 into tight contact with each other. After the chuck jig 26 is lowered and the concave pins 27 penetrate the holes 17 of the laminate 7, the negative pressure generator 25 on the chuck jig 26 is turned ON, creating a negative pressure between the suction bellows 29 and the laminate 7, further enhancing their tight contact.
[0067] Fig. 6-3 is a schematic cross-sectional view showing a state in which the chuck jig 26 is raised and receives the laminate 7 from the die mold A31. Fig. 6-3 shows a state in which the chuck jig 26 is moving away from the die mold A32 while chucking the laminate 7. The injection molding process that follows is the same as that shown in Figures 5-4A to 5-4E. In the case of the second embodiment, the cycle of the preforming process or the injection molding process must be matched to whichever is longer, which may result in expensive equipment and molds or disadvantageous depreciation. However, since the step of transferring the laminate to the receiving jig 22 is not required, the cost of the receiving jig 22 can be reduced. [Explanation of symbols]
