BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a plate-shaped body with a mounting member used when mounting a plate-shaped body for a window on a window opening, and more particularly to mounting the plate-shaped body on the window opening with an adhesive. At this time, the present invention relates to a method for manufacturing a plate-shaped body having a member for positioning and temporarily fixing the plate-shaped body in the window opening.

[0002]

2. Description of the Related Art A plate member for a window is attached to the window opening with a sealant such as urethane interposed between the window member and the plate member. Alternatively, there is also a method in which a clip, a stud bolt, or the like attached to the plate-shaped body is inserted into a predetermined hole of the window opening to attach the plate-shaped body for the window to the window opening.

In the former case, a clip for temporarily fixing the plate-like body or the plate-like body is attached at a predetermined position of the window opening until the window opening and the plate-like body are firmly adhered by the sealant. A clip or the like for such positioning may be attached to the plate-shaped body. In the latter case, a water-tight sealant such as a butyl sealant is additionally provided between the window opening and the plate-like member to ensure the watertightness of the window. The former sealant such as urethane has a water leakage preventing effect itself.

The members used to attach the plate-like members such as stud bolts and clips to the window opening (hereinafter collectively referred to as attachment members) are directly attached to the plate-like member as described above. In some cases, when the plate-shaped body is attached to the window opening, the plate-shaped body may be attached to a synthetic resin frame integrally formed with the peripheral edge of the plate-shaped body.

The attachment member is attached to the plate-shaped body or the frame body by adhesive bonding with a sealant such as urethane or a double-sided tape interposed between the attachment member and a predetermined position of the plate-shaped body. It

[0006]

Generally, the mounting member is mounted so as to extend in the direction normal to the surface of the plate-shaped body. Therefore, the orientation of the mounting member is easily influenced by the curvature of the plate-shaped body. In order to increase the accuracy of the orientation of the mounting member, it is necessary to control the curvature of the mounting member and the plate-shaped body more than ever, and the jigs and tools for bonding must be specialized. Furthermore, if the orientation of the mounting member is to be set arbitrarily, it is necessary to devise the shape of the mounting member itself. In particular, when a plurality of mounting members are used, as many kinds as the number used are required.

Further, when a urethane sealant is used for mounting the mounting member to the plate-shaped member, it takes time for the urethane sealant to harden, so it is necessary to secure a space for storing these.

On the other hand, when the mounting member is mounted on the frame, the mounting member is usually arranged on the inner surface side of the frame. If a water leakage prevention sealant is separately applied between the frame and the window opening, the above-mentioned mounting member will be placed on the outer peripheral side of this sealant, so that the watertightness is low and the watertightness is low. Water leakage prevention parts such as packing are further required to prevent leakage.

Therefore, it is conceivable that the mounting member is disposed on the inner peripheral side of the water leakage preventing sealant by widening the width of the frame body toward the inner peripheral side of the plate-shaped body. However, in this case, the thickness of the entire window becomes thicker by the thickness of the sealant, and an extra frame material is required for widening the inner circumferential side.

As a means for preventing an increase in the material of the frame body while arranging the mounting member on the inner peripheral side of the sealant for preventing water leakage, the inner periphery of the frame body is provided only at a portion where the mounting member is arranged as a pedestal of the mounting member. It has been proposed to provide an overhang to the side. Integral molding of the frame body to the peripheral edge of the plate-like body,
This is performed by sandwiching the peripheral edge of the plate-shaped body in a resin molding die and injecting the resin into the cavity space of the die. Therefore, by providing a bridge-shaped resin material guide path in this mold, the pedestal can be formed integrally with the plate-like body, and the mounting member is attached to the pedestal.

However, since the portion formed by the guide path of the bridge-shaped resin material is a part of one round at a certain distance from the end face of the plate-like body, the portion which is projected to the inner circumferential side is inevitable. A gap is created due to the step between the non-existent portion and the water leakage prevention cannot be sufficiently achieved. Furthermore, for the bridge-shaped portion and the plate-shaped body, which are parts of the frame body, it is necessary to prepare a primer that is appropriately used when applying the water leakage prevention sealant.

By removing the bridge-shaped portion after molding, the pedestal of the mounting member is provided on the plate-like member, and the sealant for preventing water leakage can be applied to the plate-like member surface on the outer peripheral side thereof without any step. . However, even if such a method is taken, an extra process is required to remove the bridge-shaped portion. Further, this work has a drawback that there is a risk of damaging the plate-like body.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a peripheral edge portion of a window plate member is held by a resin molding die including at least two die portions. A mounting member is mounted in a cavity space formed by a concave portion provided at a position corresponding to the inner peripheral side by a predetermined distance from one end of the plate-shaped body and one side surface of the plate-shaped body; A pedestal molding resin material for the mounting member is injected into the cavity space to be solidified, and the mounting member and the mounting member pedestal are integrally molded on one side surface of the plate-shaped body. It is a manufacturing method of a plate member for a window with a mounting member.

The present invention will be described in detail below with reference to the drawings. FIG. 1A is a schematic cross-sectional view showing an example of a method for manufacturing a window plate-shaped body with a mounting member according to the present invention,
FIG. 1B is a modification thereof. The resin molding die 30 has an upper die 5, an intermediate die 6 and a lower die 7, and a resin flow path 8 including a sprue, a runner and a gate is formed between the upper die 5 and the intermediate die 6. ing. A concave portion 22 is provided on the lower surface of the intermediate die 6, and the peripheral edge portion of the plate-shaped body 1 is provided with the intermediate die 6 and the lower die 7.
When sandwiched by and, a cavity space is formed by the concave portion 22 and one side surface of the plate-shaped body 1.

At this time, it is preferable to provide a packing 10 made of urethane rubber or the like for softly sandwiching the plate-shaped body 1 at a portion of the lower die 7 which is in contact with the plate-shaped body 1. Further, it is preferable that the portion of the intermediate die 6 which is in contact with the plate-shaped body 1 is provided with an absorbing member 9 made of fluororubber or the like capable of absorbing the deviation of the curvature of the plate-shaped body 1.

The recess 22 has a substantially stepwise vertical cross section, and has a deep portion 22a and a shallow portion 22b. The resin flow path outlet 11 is provided in the shallow portion, and the resin material is injected from the resin flow path outlet 11 into the cavity space. The mounting member 21 is attached to the deep portion 22a of the recess 22.

At this time, as a preferable shape of the mounting member 21, the upper mounting member main body portion 21a has a substantially conical shape, and the bottom portion 21b has a flat plate-shaped portion.
This flat plate-shaped portion functions as a lid that partitions the upper surface of the cavity space, and can prevent the resin material from flowing upwards, which is the mounting member mounting portion 22c of the recess 22. Further, since the mounting member 21 has a substantially conical shape,
Is securely attached to. The function of the above lid may not be provided in the mounting member itself, but may be separately provided with a means for preventing the resin material from flowing into the mounting member mounting portion. Done.

In this way, a mounting member is attached to the deep portion 22a of the concave portion 22, the plate-shaped body 1 is sandwiched between the intermediate mold 6 and the lower mold 7, and the resin material is injected into the cavity space to be solidified and the gold By removing the plate-shaped body from the mold, the pedestal of the mounting member is integrally molded with the mounting member into the plate-shaped body.

The mounting member main body may have a substantially triangular cross-section instead of the above-mentioned conical shape. That is, it is also possible to exemplify a body provided with a leaf spring function which has a divergent shape toward the bottom from the tip of the body.
In this case, the mounting member can be prevented from falling off after mounting, and the mounting member can be prevented from being displaced due to the pressure of the resin material.

Further, the concave portion has three steps, and only the main body is attached to the uppermost step of the stairs, and the boundary between the middle step and the uppermost step is covered with the flat plate portion at the bottom, whereby the flat plate portion is formed. Even if the upper side of the middle stage is engaged and the resin material is injected into the cavity space, the resin material does not leak to the main body side due to the resin pressure, which is preferable (see FIG. 1B).

The plate in the present invention may be a flat plate or a curved plate, and its material may be a single plate glass, a multi-layer glass, or at least one glass. Various materials such as a glass plate such as a laminated glass in which a plate and a synthetic resin film are adhered, an organic transparent resin plate, and a laminate of a plurality of these are used.

In view of improving the adhesiveness between the plate-shaped member and the mounting member pedestal, urethane-based, acrylic-based,
It is preferable to apply a primer treatment using an adhesive such as nylon-based, phenol-based, polyester-based or silane-based adhesive. Further, it is preferable to apply an appropriate adhesive to the mounting member as well because the adhesiveness between the mounting member and the pedestal is improved.

The material of the pedestal in the present invention is, for example, polyvinyl chloride, a vinyl chloride / ethylene copolymer,
Vinyl chloride / vinyl acetate copolymer, vinyl chloride / propylene copolymer, vinyl chloride / ethylene / vinyl acetate copolymer at least one kind or a mixture of two or more kinds is used as a base resin, and a plasticizer or the like is added. It is a compound obtained by adding an agent to form a soft material, and may be blended with another thermoplastic resin in order to enhance fluidity.

The thermoplastic resin to be blended includes chlorinated polyethylene resin, urethane-modified vinyl chloride resin, urethane resin, polyester resin, acrylic resin, polyester elastomer, rubber containing at least NBR or SBR, EVA, ABS. At least 1
One kind or a mixture of two or more kinds is used.

Although these materials are molded by ordinary injection molding, the pedestal in the present invention may be molded by reaction injection molding in which a reactive urethane resin material is injected. Furthermore, examples of the material used include thermosetting resin materials. It is preferable to use the hot runner method capable of reducing the material content of the resin flow path portion or the above-mentioned reusable thermoplastic resin.

A frame body made of synthetic resin may be integrally formed on the peripheral edge of the plate-shaped body so as to be interposed between the window opening and the plate-shaped body. When the frame body is formed of the same material as the pedestal, the second cavity space is provided at a position on the outer peripheral side of the plate-shaped body with respect to the recessed portion of the mold, so that the frame body is formed by the recessed portion and the plate-shaped body. By simultaneously injecting the resin material into the first cavity space and injecting the resin material into the second cavity space, the pedestal and the frame body can be easily integrally molded into a plate-shaped body.

The resin molding die of the present invention includes
Ordinary metal molds can generally be used. Number of production lots,
By controlling the injection pressure of the resin material, inexpensive molds such as heat resistant resin molds can be used. In the above example, the resin molding die is made up of three die parts, but it is sufficient if it is made up of at least two die parts, and depending on the structural requirements of the sprue, runner, gate, etc., It can be determined appropriately.

For example, as shown in FIG. 1 (b), one mold part consisting of an upper mold 15 and an intermediate mold 16 joined to form a sprue, a runner, and a gate (resin flow path 8), and a plate. A mold part made up of a backup member 17 (which preferably has a packing on the contact surface with the plate-like body) for preventing the resin material of the plate-like body 1 from being bent or damaged by the injection pressure is defined as two mold parts. It is preferable to construct a resin molding die. This is only necessary for the plate
This is because the two mold parts (the upper mold 15 and the part of the intermediate mold 16 of the intermediate mold 16 and the backup member 17) are sandwiched, so that the plate-like body can be prevented from being damaged.

The shape of the resin flow path outlet is not particularly limited, and after the resin material is solidified, the molded pedestal and the resin flow path are reliably separated from each other, and the finishing of the molding surface is unnecessary. The outlet diameter is preferably 2 mm or less.

The shape of the recess provided in the mold is appropriately determined according to the shape of the mounting member, the shape of the window opening, and the like. Therefore, the vertical cross section is not limited to the substantially stepwise shape as in the above example, but a deep portion and a shallow portion are provided in the recess, that is, a portion where the pedestal to be formed has a high height and a low portion. It is preferable to provide the recess with a depth such that the and are formed because post-finishing of the molded pedestal can be unnecessary.

The reason why the post-finishing is unnecessary is as follows. Generally, after resin molding, a small protrusion is formed at the resin flow path outlet due to the resin material protruding and solidifying. If the small protrusion is at the top of the pedestal, that is, at the same height as the position where the mounting member for the pedestal is mounted, the adhesion between the two becomes poor when the plate-shaped body is mounted in the window opening. Therefore, it is necessary to remove these small protrusions, but the number of complicated steps increases. Therefore, if the small protrusion is formed one step below the mounting member of the pedestal to be molded, the above post-finishing is not necessary.

For that purpose, it is preferable to provide a deep portion and a shallow portion in the recess, attach a mounting member to the deep portion, and provide the resin flow path outlet in the shallow portion. Also,
In some cases, it is possible to eliminate the need for post-finishing by providing a resin flow path outlet on the side surface of the recess, but it is preferable to provide the resin flow path outlet in the shallow portion in view of the fluidity of the resin.

As the mounting member, even if the member for mounting and fixing (finally fixing) the plate-like member to the window opening is interposed, the plate-like member is interposed between the plate-like member and the window opening. It may be responsible for positioning and temporary fixing until the sealant such as urethane, which is fixed to the window opening (fixed), is solidified. In the former case, a water leakage prevention sealant is interposed between the plate-shaped body and the window opening on the outer peripheral side of the plate-shaped body with respect to the mounting member, if necessary. On the other hand, in the latter case, the sealant itself such as urethane functions as a sealant for preventing water leakage.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a schematic cross-sectional view showing an example of a method for manufacturing a window plate-shaped body with a mounting member according to the present invention. The resin molding die 40 has an upper die 5, an intermediate die 6 and a lower die 7, and a resin flow path 8 including a sprue, a runner and a gate is formed between the upper die 5 and the intermediate die 6. ing. A concave portion 22 is provided on the lower surface of the intermediate die 6, and when the peripheral edge portion of the plate-shaped body 1 made of a curved single glass plate is sandwiched between the intermediate die 6 and the lower die 7, the concave portion 22 and the plate are A cavity space is formed by the one side surface of the body 1. Further, at a position corresponding to the outer peripheral side of the concave portion 22 of the intermediate mold 6 and the lower mold 7, the plate-shaped body 1 is formed by the inner wall of the intermediate mold 7, the inner wall of the lower mold 7 and the peripheral edge of the plate-shaped body 1. The second cavity space 31 is formed so as to circulate.

A portion of the lower die 7 of the plate-shaped body 1 that abuts the plate-shaped body 1 is provided with a packing 10 made of urethane rubber that flexibly clamps the plate-shaped body 1. An absorbing member 9 made of fluororubber capable of absorbing the deviation of the curvature of the plate-shaped body 1 is provided in a portion that contacts the plate-shaped body 1.

The recess 22 has a substantially stepwise vertical cross section, and has a deep portion 22a and a shallow portion 22b. The mounting member 21 is mounted in the deep portion of the recess 22. Further, the resin flow path outlet 11 is provided in the shallow portion, and the soft vinyl chloride compound resin material is injected from the resin flow path outlet 11 into the cavity space. On the other hand, the second resin flow path outlet 12 is provided on the inner wall forming the second cavity space 3 of the intermediate mold 7, and the resin flow path outlet 1
Simultaneously with the injection from No. 1, the resin material is injected from the second resin flow path outlet 12 into the second cavity space 31.

In this way, the mounting member is mounted in the deep portion of the recess 22, the plate-shaped body 1 is sandwiched between the intermediate mold 6 and the lower mold 7, and the resin material is injected into the cavity space to be solidified, and then the intermediate space is formed. The plate 6 is removed from the mold by releasing the mold 6 and the lower mold 7 and breaking the resin at the resin flow path outlet 11, and the pedestal of the mounting member is integrally molded with the mounting member into the plate. It was At this time, even if small protrusions remain in the lower stage of the pedestal having a substantially stepped cross section due to the resin being torn off, post-finishing for removal is unnecessary.

In this example, a plurality of holes are provided at the bottom of the mounting member. When the resin material is injected into the cavity space, the resin material also flows into this hole. As a result, after the resin material is solidified, the bottom portion of the mounting member and the pedestal are more firmly integrated, which is preferable.

FIG. 3 is a schematic perspective view showing an example of a plate-like member with a mounting member manufactured as described above, and FIG.
FIG. A frame body 3 made of synthetic resin is integrally formed on the peripheral portion of the plate body 1, and an inner peripheral side thereof is integrated with a pedestal 2 of a mounting member integrally formed on one side surface side of the plate body 1. The mounting member 21 is formed into a single piece.

When the plate-shaped member with a mounting member thus obtained is used as a vehicle fixed window, the mounting member 21 is inserted into a positioning hole provided at a predetermined position in the opening of the vehicle window.
The plate-shaped body 1 can be positioned and held in the window opening by inserting. In this example, the small protrusions 29 remain on the lower stage of the pedestal 2 having a substantially stepped cross section, but the remaining position of the small protrusions 29 is a position that does not affect the positioning of the plate-shaped body. Further, a water leakage preventing sealant 4 is laminated between the frame 3 on the surface of the plate-like body 1 and the pedestal 2 of the mounting member,
The plate member with the attachment member is attached to the window opening.

When the mounting member 21 itself can fix the plate-shaped member 1 to the window opening, a butyl sealant or the like is used as the water leakage sealant. If it is poor, a urethane sealant or the like is used as the water leakage sealant. In the latter case, the attachment member 21 has a function of temporarily holding the plate-shaped body 1 at a predetermined position in the window opening until the urethane sealant is solidified and the plate-shaped body is fixed to the window opening. . In this embodiment, a resin molded product made of polyacetal is used as the mounting member, but the mounting member is not limited to this.

[0042]

According to the present invention, the pedestal of the mounting member is integrally formed on one side surface on the inner peripheral side by a predetermined distance from the end surface of the plate-like member, and therefore is applied when the plate-like member is attached to the window opening. The sealant for preventing water leakage can be provided on the outer peripheral side of this pedestal, which can prevent an increase in the number of parts and an extra process.
In particular, when the frame body is integrally formed on the peripheral portion of the plate-shaped body at the same time, the step of removing the bridge-shaped portion of the resin which has been conventionally used can be eliminated. Moreover, by eliminating this removing step, the plate-shaped body is not damaged.

The cavity is formed in the mold so that the pedestal to be molded has a step, and the resin material is injected into the cavity from a portion corresponding to a low step of the pedestal. There is no need to remove the small protrusions of resin that are formed on the pedestal.

Further, according to the present invention, since there is no restriction on how to attach the attachment member to the mold, the extending direction of the attachment member is not limited to the normal direction of the plate-like member, and the window opening or It can be oriented in an appropriate direction depending on the design of the plate-shaped body. As for the mounting position of the mounting member, it can be mounted on the plate in the required number at the required position according to the purpose of temporary fixing, permanent fixing, etc. and the size of the plate. It is possible to obtain a method of manufacturing a plate-shaped body with a mounting member having an increased degree of freedom.
