Abstract

PURPOSE:To prevent falling down of hairs from being generated through heat and pressure, and a partial change of color from being generated, by a method wherein an air blowing pipe is communicated with a mold surface of a receiving mold, a part covering an ornament member out of a synthetic resin skin material is floated from the surface of the member, and vacuum molding is performed. CONSTITUTION:An ornament member 21 is attached partially to the surface of a base material 11, and a die 5 is set up to a mold surface of a broken receiving mold 1. A vinyl chloride resin sheet having a foamed layer is set up on the upper part of the same under a state where the resin sheet is softened by heating at 150 deg.C as a synthetic resin skin material 31, and the die 5 and receiving mold 1 are clamped together. In this instant, though the die 5 comes into contact with the base material 11, air of atmospheric pressure or higher which is preferably 2-6 kg/cm<2> is blown through an air blowing pipe 4 being communicated with the mold surface of the receiving mold 1 directly before the contact. Then a part out of the synthetic resin skin material 31, which is on the upper part of an ornament member 21 is floated toward a cave part 6 to be formed between the die 5 and receiving mold 1. On the one hand, vacuum molding of the synthetic resin skin material 31 being heated and softened through a vacuum box 2 connected with a vacuum source and a vacuum suction hole 3 arranged on the receiving mold 1 is performed on the surface of the base material.

た。(Problems to be Solved by the Invention) However, in this type of conventionally known method, it is difficult to coat a synthetic resin skin material on the surface of a base material to which a raised ornament member is partially attached. , a synthetic resin skin material is heated and set on the front side of the base material, and then the ornament material is vacuum formed by applying negative pressure from the back side of the base material so as to completely cover the surface of the base material. Therefore, during vacuum forming, the heated synthetic resin skin material is pressed onto the surface of the ornament member, causing hair to fall and whitening, making it difficult to obtain a good-quality product with a good appearance. In the case of certain molded base materials, this tendency is remarkable in the white part.Furthermore, when vacuum-formed synthetic resin skin materials are cooled, residual stress is generated, and the welded parts are damaged during the subsequent welding process with ornament parts. This may cause defects such as cracks, tears, and loose welds in the synthetic resin skin material, so the part of the synthetic resin skin material that covers the ornament member should be cut out immediately after vacuum forming, or the residual stress should be removed. In order to prevent this, there is a concern that the heating temperature of the synthetic resin skin material may be raised to increase the degree of plastic deformation.For this reason, in the former case, complicated measures are required, and in the latter case, the design quality may be affected due to overheating. There were problems such as damage to the

This method was completed for the purpose of producing an automobile interior material that can be used as an interior material for automobiles.The surface of a base material partially attached with a raised ornament member is coated with a synthetic resin skin material, and this is applied around the periphery of the ornament member. A base material to which a brushed ornament member is partially added, in a method for manufacturing an automobile interior material, in which a portion of the synthetic resin skin material covering the ornament member is removed along the weld line while being welded. When applying synthetic resin skin material to the surface, the part of the synthetic resin skin material that covers the ornament member is raised slightly above the surface of the ornament member, and the heated synthetic resin skin material and the ornament member are brushed. It is characterized by vacuum forming while cutting off contact with the parts.

The effect is particularly remarkable when a molded base material with unevenness is used. Next, as an ornament material to be covered on the surface of the base material, fabrics such as moquette fabric, curved fabric, and 7-tooth fabric with a raised length of about 0.5 to 10 mm are woven from chemical fibers, natural fibers, and other arbitrary fibers. Materials with relatively long naps such as woolen fabrics and flocked fabrics, while synthetic resin skin materials do not particularly matter as long as they can be welded by high frequency welding or other means, but in general heat A solid type sheet made of plastic synthetic resin or a laminated type sheet with a foam layer is used, and depending on the material, a synthetic resin adhesive layer for welding such as true melt adhesive is previously formed on the back side of the part to be welded. Further, the welding means for welding the synthetic resin skin material to the peripheral edge of the ornament member may be performed by using an ultrasonic welder or any other welder in addition to the high-frequency welder.

11) Has a nap of 2 lengths on the surface and has a softening point of 90℃
The ornament member (21) is attached to the base material (11) by partially adhering a fabric piece made of polyester fiber of ) is partially attached to the surface of the assist mold (5), which is then set on the mold surface of the receiving mold (1) from which the assist mold (5) has been opened, and the synthetic resin skin material (31 ) A vinyl chloride resin sheet having a foam layer is heated and softened at 150° C. and set, and the assist mold (5) and the receiving mold 10 are clamped. At this time, at the same time or just before the assist mold (5) comes into contact with the base material (11), the air blowing pipe (4), which is connected to the mold surface of the receiving mold (1), is pressed at a pressure higher than atmospheric pressure b). 2 to 3 kir/- of air is blown into the part of the synthetic resin skin material (31) above the ornament member (21) into the cavity formed between the assist mold (5) and the receiving mold (1). (6) The synthetic resin skin is heated and softened through the vacuum box (2) connected to a vacuum source and the vacuum suction hole (3) provided in the mold (1) while being lifted up. When the material (31) is vacuum formed on the surface of the base material, the ornament member (2) is formed on the mold surface of the assist mold (5).
Since the pressing protrusion (8) is provided so as to correspond to the outer shape of item 1), this pressing protrusion (8) presses the peripheral portion of the ornament member (21) together with a part of the synthetic resin skin material (31). The synthetic resin skin material (31) is pressed against the base material (11) on the receiving mold (1), and the synthetic resin skin material (31) is separated from the part covering the ornament member (21) and the base material (11) using the peripheral edge of the ornament member (21) as the boundary. It is divided into a part that covers the ornament member (21), and airtightness is maintained so that the part that covers the ornament member (21) can be lifted up by air blowing and the other parts can be properly vacuum formed, and heated during vacuum forming. The contact between the synthetic resin skin material (31) and the raised portion of the ornament member (21) is cut off, and therefore the ornament member (21)
It is possible to completely prevent hair fall and whitening phenomena that occur when the base material (1) is pressed against the heated synthetic resin skin material (31) during vacuum forming. The expansion rate of the skin material (31) is low due to partial lifting, and therefore residual stress can be reduced without taking the trouble of cutting out a part immediately after vacuum forming or increasing the heating temperature. Can be done. Note that even if a part of the synthetic resin skin material is welded to the periphery of the ornament member (21) by using the pressing protrusion (8) as a welding electrode of a high-frequency welder or the like, another process may be performed in the next step. Although welding may be performed using a welding device, the ornamental member (2) of the synthetic resin skin material (31) may also be welded during welding.
By raising the part that covers 1), it is possible to prevent the part adjacent to the welding line forming part from coming into contact with the raised part of the ornament member (21) when pressed by the welding electrode, so that the part covering the welding line can be raised. It is also possible to prevent whitening of the ornament member (21), which tends to occur along the edges. In addition, in the above description, air is blown as a means for lifting the part of the synthetic resin skin material (31) that covers the ornament member (21), but as shown in FIG. When performing vacuum forming without using an assist mold, a vacuum cap (9) with a pressing protrusion (8) at the leg end is provided above the receiving mold (1), and the vacuum cap (9) is placed above the receiving mold (1). A part of the coated synthetic resin skin material (31) is placed around the periphery of the ornament member (21) in the vacuum camp (
9) It is also possible to reduce the pressure inside the vacuum cap (9) while pressing with the pressing protrusion (8) at the end of the zero leg, and to float it up with this suction force. The synthetic resin skin material (31) is not covered directly, but the cutter material is added in advance, or the receiving mold (11) and the assist mold (5) are arranged to face each other from side to side instead of facing each other vertically. After welding, the synthetic resin skin material (
31), the portion covering the ornament member (21) may be removed or thinned to the extent that it can be easily removed, and then removed to expose the ornament member (21).

の発展に寄与するところ極めて大きいものがある。(Effects of the Invention) As is clear from the above description, the present invention is characterized in that when vacuum forming a synthetic resin skin material, the part covering the ornament member is slightly raised, and the synthetic resin is heated against the nap of the ornament member. By simply applying a process to eliminate contact between the synthetic resin skin material and the ornament material, it is possible to prevent hair falling and the accompanying whitening phenomenon that occurs due to the heat and pressure applied during vacuum forming. In order to remove the residual stress caused by the temperature change of the material or the tension applied to the part covering the ornament member, the part of the synthetic resin skin material that covers the ornament member may be incised, or the heating temperature of the synthetic resin skin material may be adjusted. Because it does not require the complicated methods used in the past, such as increasing the There are some methods that can greatly contribute to the development of the industry by solving problems in manufacturing methods.

Detailed Description of the Invention (Field of Industrial Application) The present invention facilitates the production of a good-looking automobile interior material in which the surface of a base material is covered with an ornamental material such as moquette or carpet material and a synthetic resin skin material. The present invention relates to a manufacturing method and manufacturing equipment for automobile interior materials that can be mass-produced. (Prior art) A synthetic resin skin material is completely coated on the surface of a base material to which a raised ornament member such as carpet material is partially attached, and this is welded to the periphery of the ornament member. A method of manufacturing an automobile interior material in which a portion of the synthetic resin skin material covering the ornament member is removed along the welding line is widely known, such as in Japanese Patent Publication No. 59-24008. (Problems to be Solved by the Invention) However, in this type of conventionally known method, in order to cover the surface of a base material partially attached with an ornament member with a synthetic resin skin material, a synthetic resin The surface material is heated and placed on the front side of the base material, and then vacuum formed using negative pressure applied from the back side of the base material so as to completely cover the surface of the base material on which the ornament member is attached. Therefore, during vacuum forming, the heated synthetic resin skin material is pressed onto the surface of the ornament member, causing hair to fall and causing partial color change, making it difficult to obtain a good-quality product with a good appearance. When the base material is a molded base material with unevenness, this tendency is remarkable in the white part. Furthermore, when vacuum-formed synthetic resin skin material is cooled, residual stress is generated, and during the subsequent welding process with ornament parts, the synthetic resin skin material at the welded area may cause defects such as cracks, tears, and welding. To prevent plastic deformation, the part of the synthetic resin skin material that covers the ornament member may be cut out immediately after vacuum forming, or the heating temperature of the synthetic resin skin material may be raised to prevent residual stress. Therefore, in the former case, complicated means are required, and in the latter case, there are problems such as overheating, which impairs the design. (Means for Solving the Problems) The present invention solves the above-mentioned problems and provides an automobile interior that can be easily coated with a synthetic resin skin material by a vacuum forming method without causing a color change phenomenon on ornament members. This method was completed for the purpose of manufacturing a material, in which a synthetic resin skin material is coated on the surface of a base material partially attached with an ornament member, and this is welded to the periphery of the ornament member, and the synthetic resin is In a manufacturing method for an automobile interior material in which the part of the ornamental skin material that covers the ornament member is removed along the welding line, a synthetic resin skin material is applied to the surface of the base material to which the raised ornamental material is partially attached. When covering the ornament material, the part of the synthetic resin skin material that covers the ornament member is slightly raised above the surface of the ornament member to prevent contact between the heated synthetic resin skin material and the raised part of the ornament member. The first invention is a method for manufacturing an automobile interior material characterized by vacuum forming while cutting, and a receiving mold for placing a base material provided with vacuum suction holes, and a mold that can be freely matched to the receiving mold. 1! An automobile interior material in which a synthetic resin skin material is placed between the presser die and the mold and the synthetic resin skin material is vacuum formed on the surface of the base material. Manufacturing of an automobile interior material, characterized in that the receiving mold is provided with an air blowing pipe whose base end is connected to an air supply source and whose tip communicates with a part of the mold surface of the receiving mold. The device is a second invention. The base material used in the present invention may be of any material such as a synthetic resin board or hard fiber board, and may have a flat structure or a molded base material with irregularities.
This effect is particularly noticeable when a molded base material with irregularities is used.Next, the ornamental member to be covered on the surface of the base material may be woven or knitted with chemical fibers, natural fibers, or any other fiber. Any fiber fabric is fine, but in particular,
The effect is remarkable when the material has relatively long naps, such as moquette fabrics, carpet fabrics, and flocked fabrics with a nap length of about 0.5 to 10 mm·υ. On the other hand, the synthetic resin skin material may be of any material as long as it can be welded by high frequency welding or other means, but in terms of -C, it may be a solid type made of thermoplastic synthetic resin or a laminated type with a foam layer. A sheet ta is used, and depending on the material, a synthetic resin adhesive layer for welding, such as a hot melt adhesive, may be previously formed on the back surface of the part to be welded. Furthermore, the welding means for welding the synthetic resin skin material to the periphery of the ornament member is also available in addition to the high-frequency welder.
This may be done using an ultrasonic well or any other welder. (Embodiment) Next, an embodiment of the present invention will be described in detail with reference to the drawings. +11 is a receiving mold whose lower part is a vacuum box (2), and the mold surface has vacuum suction holes (3). ) is formed on a concave-convex mold surface, and a part of this mold surface is connected to an air blowing pipe (4) connected to an air supply source.(5) is a receiving mold (1). ) is an assist mold as a holding mold which is arranged so as to be freely moldable, and most of the mold surface of the assist mold corresponds to the mold surface of the receiving mold (1), Only a portion of the receiving mold (11) that faces the part where the ornament member is placed has a required cavity (6
) is sufficient to form a concave surface. In addition, (7) in the figure shows that when setting the base material on the mold surface of the receiving mold (1), in order to maintain the balance of the base material and enhance the sealing effect,
A soft sealing material (8) is partially embedded in the mold surface of the receiving mold +11 so as to slightly protrude from the mold surface of the holding mold (5).
) is a pressing projection provided on the mold surface so as to correspond to the outer shape of the ornament member, 01 is a ventilation hole that opens the cavity (6) of the holding mold (5) to the atmosphere, and (11) is a receiving mold. (1
), the base material (11)
The base material (11) is made by pre-forming a synthetic resin board or a hard fiber board into a textured one and providing a large number of small holes for suction, and part of the surface of the base material (11) has a raised length of 0.5. ~lO
Carpet fabric or moquette fabric made of polyester or polyamide fibers with a softening point of about 70 to 120 degrees Celsius is cut into the desired shape after attachment, or an ornament material (previously cut into the required shape and attached to the bag) 21) is pasted, and (31) is a synthetic resin skin material with a foam layer laminated on the back side if necessary, and the synthetic resin skin material (31) is made of vinyl chloride resin or polyethylene. It is made of vacuum-formed resin or thermoplastic synthetic resin such as thermoplastic polyester resin and weldable leather or film material, and is not melted but is sufficiently softened at an optimum temperature of, for example, about 100 to 200°C. It is set between a receiving mold (11) and a presser mold (5) in a heated state.Next, a specific example of manufacturing an automobile interior material using the above-mentioned apparatus and materials will be described. First, the base material (
11) has a nap of 2fl length on the surface and has a softening point of 90
The ornament member (21) is attached to the base material (21) by partially pasting the fabric lifter strip made of polyester fiber at 30°C to the convex portion formed on the surface of the base material and trimming it into the desired shape. 11), and place it on the mold surface of the receiving mold (1) where the presser mold (5) is opened, and add the synthetic resin skin material ( As 31), a vinyl chloride resin sheet having a foam layer is heated and softened at 150°C and set, and a presser mold (5) and a receiving mold +1. At this time, at the same time or just before the presser mold (5) comes into contact with the base material (11), the air blowing pipe (4), which is connected to the mold surface of the receiver mold (1), is used to clamp the mold. Atmospheric pressure or higher, preferably 2~
6kg/ru! Synthetic resin skin material (
31) above the ornament member (2]) into the cavity formed between the holding die (5) and the receiving die (1).
6) The synthetic resin skin material is heated and softened through a vacuum box (2) connected to a vacuum source and a vacuum suction hole (3) provided in the receiving mold (1) while being raised in the direction of the surface. If (31) is vacuum formed on the surface of the base material, the presser mold (
Since a pressing protrusion (8) is provided on the mold surface of 5) so as to correspond to the outer shape of the ornament member (21), this pressing protrusion (8) presses the peripheral portion of the ornament member (21) into the synthetic resin. A mold (
]) on the base material (11), and press the ornament member (
The synthetic resin skin material (31) is divided into a part that covers the ornament member (21) and a part that covers the base material (11) with the peripheral edge of Synthetic resin skin material (31) that is kept airtight and heated during vacuum forming to ensure proper vacuum forming of raised parts and other parts.
The contact between the raised part of the ornament member (21) and the raised part of the ornament member (21) is cut off, and therefore, the color change phenomenon caused by the hair falling when the ornament member (21) is pressed against the heated synthetic resin skin material (31) during vacuum forming is completely prevented. can be prevented,
Furthermore, when the base material fil has an uneven curved surface, the synthetic resin skin material (31) has a low development rate due to partial lifting, and therefore the troublesome process of cutting out a part immediately after vacuum forming is required. Residual stress can be reduced without increasing heating temperature. In addition, a part of the synthetic resin skin material is used as an ornament member (2
1), or may be welded using a separate welding device in the next step, but the part of the synthetic resin skin material (31) that covers the ornament member (21) may By raising the welding electrode, it is possible to prevent the part adjacent to the welding line forming part from coming into contact with the nap of the ornament member (21) when pressed by the welding electrode, which is likely to occur along the welding line. Whitening of the ornament member (21) can also be prevented. Furthermore, in the above description, air is blown as a means of lifting the part of the synthetic resin skin material (31) that covers the ornament member (21), but the ventilation hole α is connected to a vacuum source (not shown). However, the goal can be achieved. Furthermore, like the other implementation device shown in FIG. 3, a frame-shaped presser mold (5) with a pressing protrusion (8) at the leg end is provided above the receiving mold (1), and the base material (21) is Synthetic resin skin material (31) coated on the surface of
A part of the ornament member (21) may be pressed against the periphery of the ornament member (21) with the pressing protrusions (8) at the leg ends of the frame-shaped presser die (5) described above, or a part of the base material (21) may be lifted up. (
A cushioning material may be added in advance to the surface of the ornament member attached to the mold (11) without directly covering it with the synthetic resin skin material (31), or the receiving mold (11) and the assist mold (5) may be placed vertically. You can change the details as you like, such as making them face each other in the opposite direction or facing left and right.After welding, the ornament member (21) is cut out of the synthetic resin skin material (31) using a fusing blade attached to the welding electrode. ) may be removed by removing the portion covering the ornament member (21) or by thinning it to the extent that it can be easily removed to expose the ornament member (21). (Effects of the Invention) As is clear from the above description, , when vacuum forming synthetic resin skin material, the part covering the ornament member is slightly raised to prevent the heated synthetic resin skin material from coming into contact with the nap of the ornament member. It is possible to prevent hair falling and color change caused by the heat and pressure applied during vacuum forming of ornament parts, and also to remove residual stress caused by temperature changes in vacuum formed synthetic resin skin materials. In order to remove the tension applied to the part that covers the ornament, it is no longer necessary to take the complicated measures that were conventionally used, such as cutting out the part of the synthetic resin skin material that covers the ornament member, or raising the heating temperature of the synthetic resin skin material. This method simplifies the manufacturing process, does not impair the design due to overheating, has a simple structure, and can be provided at low cost. It will greatly contribute to the development of the industry as it solves the problems of manufacturing equipment. 4.
