[0002]
[Prior art]
2. Description of the Related Art A long trim material having a lip is used as a trim material such as a gasket attached to a peripheral portion of a vehicle window. In such a trim material, there is a case in which the lip changes at a different angle in each part due to a positional relationship with the vehicle body panel or a difference in functions required for the lip.
[0003]
Conventionally, as such trim materials having different lip directions, there is a long trim material obtained by joining molded materials manufactured for each part by injection molding or the like. In addition to the increase in cost, the joining portion is conspicuous and a product excellent in appearance cannot be obtained.
[0004]
In order to improve such a point, it is known that extrusion is performed so that the lip projects in the first direction, and immediately after the extrusion, the lip is plastically deformed by pushing the lip from one side in the second portion ( JP-A-59-182722).
However, in this method, since the lip is pushed and displaced from only one side, it is necessary to largely displace the lip from the position of the orifice toward the second portion, and one surface is elongated, and the surface on the opposite side is compressed and roughened. In addition to being unable to accurately control the position of the surface or the deformation, the third part that moves from the first position to the second position cannot be gradually changed in a natural manner.
[0005]
[Problems to be solved by the invention]
An object of the present invention is to solve the above-mentioned problems, in which lips whose protruding direction changes in each part are formed continuously and integrally along the longitudinal direction, and roughening or deformation due to the change is prevented. In addition, it is an object of the present invention to propose a long trim material having a lip which can gradually change in an intermediate position naturally and thereby obtain an excellent appearance, and an efficient manufacturing method and a manufacturing apparatus therefor.

In the state in which the gap is regulated, the gear 30a and 35b are rotated at the same speed in opposite directions via the driving shaft 33 and the driven shaft 34 arranged in parallel with each other, and the rotation changes the direction and the bent shape of the gap 30. However, the space between the mold surfaces 31a and 32a has substantially the same cross-sectional area, so that the protruding direction of the lip 4 is changed in the first direction Y and the second direction Z.ProtrusionIt is configured to be. It is preferable that the mold surfaces 31a and 32a are formed of a material having good slipperiness with respect to the lip 4, or that a layer having good slipperiness is formed in advance. The drive shaft 33 and the driven shaft 34 are supported by bearings 36a and 36b, and are connected to a drive source such as a servo motor (not shown). 31n and 32n are second shaping molds provided as necessary, and have the same structure as the first shaping device, but the molding material 25 passes through the first shaping device 14 and the second shaping device passes a certain time. It is designed to operate with a time delay as it passes through the shaping device.
[0013]
In the shaping molds 31 and 32, the ends 31b and 32b on the base side of the lip 4 are circles having the same diameter D, the shafts 33 and 34 are located at the center, and the ends 31c and 32c on the tip side of the lip 4 are substantially the same.

[0015]
In the method of manufacturing the trim material 1, the core material 2 is first sent out from the bobbin 11, and is continuously sent to the extrusion mold 13 in a state where the core material 2 is tensioned so that the brake 12 does not elongate. In the extrusion mold 13, the first and second resins 23 are supplied to the resin flow path 24 from the first and second resin supply paths 21 and 22, and the core 2 is embedded in the first resin. The molding material 25 in which the main body 3 having a substantially U-shaped cross section and the lip 4 and the sliding part 5 made of the second resin are integrated is extruded from the orifice 26. At this time, the lip 4 isangleAs shown by a broken line X in FIG. 6, it is formed so as to protrude in a direction (X direction) intermediate between the positions in the first direction (Y direction) and the second (Z direction). It is preferable to set the position in a direction equally dividing the (Y direction) and the second direction (Z direction).
[0016]
When the molding material 25 is in a state where at least the lip 4 can be plastically deformed, preferably in a softened state immediately after extrusion molding, the shaping device 14 slides the lip 4 between the mold surfaces 31a and 32a. Lip 4 in first and second directions in first and second portionsProtrudes. At this time, when the extruded amount of the molding material 25 is optically detected by the extruded amount detecting device 15 and the detection signal is input to the control device 20, the control device 20 converts the change signal based on a preset program into the shaping device 14. And outputs an opening signal to the valve 38.
[0017]
Accordingly, in the shaping device 14, the drive shaft 33 rotates, and the shaping dies 31, 32 rotate in opposite directions with the lip 4 interposed therebetween due to the engagement of the gears 35a, 35b. As a result, the projection direction of the lip 4 is changed from the state of the X direction at the outlet of the orifice 26, as shown in FIG. 6 in the Y directionProtrusionIn the lower portion L, which is the second position, the second direction is the minus direction, that is, the Z direction.ProtrusionAt the corner C of the lower portion L, which is the third portion between them, the first direction Y gradually moves in the second direction Z or the second direction Z gradually moves in the first direction Y.ProtrusionLet it. In addition, from the first position to the third position, or from the second position to the third positionProtrusionIn this case, it is preferable to rotate the deformation roller in the same direction as the moving direction of the molding material 25. During this time, the refrigerant is guided from the refrigerant source 37 to the refrigerant receiving grooves 31 d and 32 d through the refrigerant supply path 39, thereby cooling the shaped molds 31 and 32. Liquid nitrogen, air, or the like is used as the refrigerant, and inert nitrogen is preferable. By performing such cooling, the shaping molds 31 and 32 can be maintained at a predetermined temperature.

In the shaping device 14, both surfaces of the lip 4 are regulated by the mold surfaces 31 a and 32 a of the shaping dies 31 and 32.Change in direction of protrusionIs performed, when the lip 4 changes to the first or second position in the first, second, and third portions, both surfaces of the lip 4 are roughened or carelessly deformed in an undesirable direction. The mold surfaces 31a and 32a are transferred without any wrinkles, and an excellent appearance is obtained. The lip 4 is continuous through the first, second, and third portions, changes in a natural manner and is integrally formed, so that a trim material having an excellent appearance can be easily formed. It is preferable that both surfaces of the lip 4 and the mold surfaces 31a and 32a are always in contact with each other. However, some gaps may occur in practical use.
[0020]
By the above, of lip 4Changed the projecting directionThe molding material 25 is cooled and hardened by the cooling device 16, and when the constituent resin contains rubber or rubber, vulcanization is performed by the vulcanizing device 16a. The cured molding material 25 is taken off by a take-off machine 17, a take-off amount is detected by a take-off amount detection device 18, and cut by a cutting machine 19 driven by a command from a control device 20 based on the signal to cut the trim material 1. It is formed. The cutting by the cutting machine 19 is performed at substantially the middle V of the lower portion L in FIG. 3, whereby the trim material 1 composed of one long material having a length W is obtained. In the above-described embodiment, the shaping device is disposed immediately after the extrusion die, but it may be disposed at a position after the molding material 25 has hardened. In this case, it is necessary to reheat the lip 4 at least to a temperature at which the lip 4 can be plastically deformed. When the lip 4 is deformed after the molding material 25 has been cooled and hardened, it is possible to perform processing in separate steps.

In this embodiment, the trim material 1 is a long trim material used as a gasket or a molding of a front window, and has a main body portion 3 made of a soft synthetic resin in which a core material 2 is embedded as in FIGS. Lips,, made of rubber or synthetic resin, which are softer and more flexible than the main body 3, are formed integrally with the lips 4, 42, and 43. The lips 42 and 43 have the same cross-sectional shape throughout the entire length, but the projection direction of the lip 4 changes in the same manner as the lip 4 in FIGS.
[0025]
In this case, the lip 4 is inclined toward the window plate 6 as the first direction at the side portion S as the first portion, as shown in FIG. To prevent water on the window plate from flowing across the trim material 1, as shown in FIG. 11 (a) in the upper portion U as a second portion. 2, a water receiving portion 44 is formed between the main body 3 and the outer surface of the body panel 8 side, and a flush portion 45 is formed on the opposite side.

It is changing gradually. 46 is an opaque print layer and 47 is a dam rubber.
[0026]
The trim member 1 is attached along the outer peripheral edge of the window plate 6 of the front window of the vehicle, and is fixed by fixing means 7 such as an adhesive. In the attached state, the lip 4 is inclined at the side portion S toward the window plate 6 side, and the water receiving portion 44 is formed, so that the rainwater 48 on the window plate 6 is prevented from flowing over the trim material 1. Then, the water is collected to prevent lateral flow to the side window. In the upper portion U, the lip 4 is inclined toward the vehicle body panel (roof panel) 8 to form the water receiving portion 44, so that the rain water 48 on the vehicle body panel (roof panel) 8 is collected and the window plate is formed. 6 is prevented, and the formation of the flush portion 45 allows water on the window plate 6 to flow over the trim material 1 to the roof side due to the wind pressure during traveling, and to reduce air resistance. Make it smaller to reduce wind noise. Further, since the lip 4 is formed of a soft and flexible material, it is safe even if a human body comes into contact.
[0027]
The above-mentioned trim material 1 can be manufactured in the same manner as in the above embodiment. In this case, an extrusion mold 13 having an orifice 25 having a cross-sectional shape of the trim material 1 is used, and the lip 4 is sandwiched between the mold surfaces 31a and 32a of the shaping molds 31 and 32.Change the projection direction of lip 4By doing so, the same trim material 1 as in the above embodiment can be obtained.

Lip 4Change the projecting direction ofWhen the shaping dies 31 and 32 formed of the deformable rollers as in the above embodiment are used as the means for causing the lip 4, the positions of the mold surfaces 31a and 32a that regulate both surfaces of the lip 4 can be changed by a simple configuration and operation. Alternatively, a shaping type with a different mechanism can be used.
[0029]
Since the core material 2 does not substantially expand or contract, or expands and contracts to a foreseeable extent, the lip 4Change the projecting direction ofBy doing so, the trim member 1 having a predetermined shape can be manufactured. In this case, in addition to the core material 2 in which the strips and the like shown in FIGS. 1 and 2 are embedded in the resin main body, the decorative material 41 shown in FIG. 9A may be used as the core material, as shown in FIG. The main body 3 may be used as a core material, or a core material made of a metal deformed material may be combined with a synthetic resin, and can be manufactured in the same manner as described above. If the expansion / contraction error of the core material 2 is so small as to be practically negligible, the detection of one of the extruded amount detecting device 15 and the picked-up amount detecting device 18 causesChange in the projection direction of lip 4However, if control is performed separately using both the detection devices, a long trim material having high dimensional accuracy can be obtained even for a core material having a large expansion / contraction error.
