Description

[0001]
[Industrial application fields]
The present invention relates to a method for manufacturing a plate-like body with a mounting member used when a window-like body is attached to a window opening, and in particular, when the plate-like body is attached to a window opening with an adhesive, The present invention relates to a method for manufacturing a plate-like body having a member for positioning and temporarily fixing to a window opening.
[0002]
[Prior art]
The plate for a window is attached to the window opening with a sealant such as urethane interposed between the window opening and the plate. In addition, there is a method in which a window plate is attached to the window opening by inserting a clip, stud bolt or the like attached to the plate into a predetermined hole of the window opening.
[0003]
In the former case, until the window opening and the plate-like body are firmly bonded to each other by the sealant, positioning is performed so that the plate-like body is attached at a predetermined position of the clip or the window opening until the plate-like body is temporarily fixed. A clip or the like may be attached to the plate-like body. In the latter case, a water leak prevention sealant such as a butyl sealant is separately interposed between the window opening and the plate-like body to ensure the water tightness of the window. The former sealant such as urethane itself has a water leakage preventing effect.
[0004]
The members used for attaching these stud bolts, clips and other plate-like bodies to the window openings (hereinafter collectively referred to as attachment members) may be directly attached to the plate-like bodies as described above. However, when the plate-like body is attached to the window opening, it may be attached to a synthetic resin frame integrally formed on the peripheral portion of the plate-like body.
[0005]
The attachment member is attached to the plate-like body or the frame body by adhesively attaching a sealant such as urethane or a double-sided tape between the attachment member and a predetermined position of the plate-like body.
[0006]
[Problems to be solved by the invention]
Generally, the attachment member is attached so as to extend in the normal direction of the surface of the plate-like body. Therefore, the orientation of the mounting member is easily influenced by the curvature of the plate-like body. In order to increase the accuracy of the orientation of the mounting member, it is necessary to manage the curvature of the mounting member and the plate-shaped member more than before, and a jig for bonding must also be dedicated. Furthermore, if the direction 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 types as necessary are required.
[0007]
Further, when a urethane sealant is used for attaching the attachment member to the plate-like body, it takes time for the urethane sealant to harden. Therefore, it is necessary to secure a space for storing these.
[0008]
On the other hand, when the attachment member is attached to the frame, the attachment member is usually disposed on the inner surface side of the frame. When a water leak prevention sealant is separately applied between the frame and the window opening, the mounting member is disposed on the outer peripheral side of the sealant, so that the watertightness is low and water is not reliable. In order to prevent leakage, water leakage prevention parts such as packing are further required.
[0009]
Therefore, it is conceivable to dispose the attachment member on the inner peripheral side of the water leak preventing sealant by increasing the width of the frame body toward the inner peripheral side of the plate-like body. However, in this case, the thickness of the entire window is increased by the thickness of the sealant, and an extra frame material is required for increasing the width on the inner peripheral side.
[0010]
As a means for preventing the increase in the frame material while disposing the mounting member on the inner peripheral side of the water leak preventing sealant, only the portion where the mounting member is disposed as the base of the mounting member is provided on the inner peripheral side of the frame. It has been proposed to provide an overhang. The frame body is integrally formed on the peripheral portion of the plate-like body by sandwiching the peripheral portion of the plate-like body with a resin molding die and injecting the resin into the cavity space of the die. Therefore, by providing a guide path for the bridge-like resin material in the mold, the pedestal can be formed integrally with the plate-like body, and the attachment member is attached to the pedestal.
[0011]
However, the part formed by the guide path of the bridge-like resin material is a part of one round that is a fixed distance from the end face of the plate-like body, so there is no part that has an overhang to the inner circumference side. A gap is generated due to the difference in level, and sufficient prevention of water leakage cannot be achieved. Furthermore, for the bridge-like portion and the plate-like body, which are a part of the frame body, a primer to be used as appropriate when applying the water leakage prevention sealant must be prepared.
[0012]
By removing the bridge-like portion after molding, the mounting member base is provided on the plate-like body, and the sealant for preventing water leakage can be applied to the plate-like body surface on the outer peripheral side without any step. However, even with this method, it takes an extra step to remove the bridge-like part. Furthermore, there is a drawback that there is a risk of damaging the plate-like body by this work.
[0013]
[Means for Solving the Problems]
The present invention has been made to solve the above-mentioned problems, and is provided in one mold part by sandwiching the peripheral part of the window plate by a resin molding die comprising at least two mold parts . A mounting member on a deeper one of the two portions of the concave portion having at least two portions having different depths at a position corresponding to the inner peripheral side by a predetermined distance from the end face of the plate-like body. And injecting the resin material for forming the pedestal of the mounting member into the cavity space formed by the concave portion and one side surface of the plate-like body from the shallowest of the two portions, and solidifying A method for manufacturing a plate member for a window with a mounting member, comprising integrally forming a mounting member base together with the mounting member on one side surface of the plate member.
[0014]
Hereinafter, the present invention will be described in detail with reference to the drawings.
Fig.1 (a) is a schematic sectional drawing which shows an example of the manufacturing method of the plate member for windows with the member for attachment in this invention, FIG.1 (b) is the modification. 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 recess 22 is provided on the lower surface of the intermediate mold 6. When the peripheral edge of the plate-like body 1 is sandwiched between the intermediate mold 6 and the lower mold 7, a cavity is formed by the recess 22 and one side surface of the plate-like body 1. A space is formed.
[0015]
At this time, it is preferable to provide a packing 10 made of urethane rubber or the like that sandwiches the plate-like body 1 flexibly in a portion that contacts the plate-like body 1 of the lower mold 7. Moreover, it is preferable to provide the absorbing member 9 made of fluororubber or the like that can absorb the deviation of the curvature of the plate-like body 1 in the portion that contacts the plate-like body 1 of the intermediate die 6.
[0016]
The concave portion 22 has a substantially stepped 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 a resin material is injected from the resin flow path outlet 11 into the cavity space. A mounting member 21 is attached to the deep portion 22 a of the recess 22.
[0017]
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 portion, so that the flat plate portion defines the upper surface of the cavity space. It functions as a lid, and can prevent the resin material from flowing upward, which is the mounting member mounting portion 22c of the recess 22. In addition, the attachment member 21 is securely mounted in the recess 22 by being substantially conical. The function of the lid may be provided with means for preventing the inflow of the resin material to the mounting member mounting portion without providing the mounting member itself. Made.
[0018]
Thus, the mounting member is mounted on the deep portion 22a of the recess 22, the plate-like 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. The pedestal of the mounting member is integrally molded into the plate-shaped body together with the mounting member by taking out the cylindrical body.
[0019]
As the mounting member main body portion, a member having a substantially triangular cross section can be used even if it is not the above-mentioned conical shape. That is, the thing provided with the leaf | plate spring function which makes a divergent shape toward the bottom part from the front-end | tip of a main-body part can be illustrated. In this case, it is possible to prevent the mounting member from falling off after mounting, and the mounting member can be prevented from being displaced due to the pressure of the resin material.
[0020]
Furthermore, the stepped shape of the recess is made up of 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, so that the flat portion is the upper side of the middle step Even if the resin material is injected into the cavity space, it is preferable that the resin material does not leak to the main body side due to the resin pressure (see FIG. 1B).
[0021]
The plate-like body in the present invention may be a flat plate or a curved one, and the material thereof includes a single plate glass, a multi-layer glass, and a composite with at least one glass plate. Various materials such as a glass plate such as laminated glass bonded with a resin film, an organic transparent resin plate, and a laminate of a plurality of these are used.
[0022]
In view of improving the adhesion between the plate-like body and the mounting member pedestal, the position where the plate-like mounting member base is provided is urethane-based, acrylic-based, nylon-based, phenol-based, polyester-based in advance. The primer treatment is preferably performed using an adhesive such as silane. In addition, it is preferable to apply an appropriate adhesive to the mounting member because the adhesiveness between the mounting member and the pedestal is improved.
[0023]
Examples of the pedestal material in the present invention include polyvinyl chloride, vinyl chloride / ethylene copolymer, vinyl chloride / vinyl acetate copolymer, vinyl chloride / propylene copolymer, vinyl chloride / ethylene / vinyl acetate. A mixture of at least one or two or more types of copolymers is added as a base material with additives such as plasticizers and compounded as a soft material, and blended with other thermoplastic resins to improve fluidity. You can also.
[0024]
The thermoplastic resin to be blended is at least one of chlorinated polyethylene resin, urethane-modified vinyl chloride resin, urethane resin, polyester resin, acrylic resin, polyester elastomer, NBR or SBR, at least one of EVA, ABS Alternatively, a mixture of two or more kinds is used.
[0025]
These materials are molded by ordinary injection molding, but the pedestal in the present invention may be molded by reaction injection molding in which a reactive urethane resin material is injected. Furthermore, a thermosetting resin material is also used as a material to be used. It is preferable to use the hot runner method that can reduce the material content of the resin flow path portion or the above-described thermoplastic resin that can be reused.
[0026]
A synthetic resin frame member interposed between the window opening and the plate member may be integrally formed at the peripheral edge of the plate member. When this frame is formed of the same material as the pedestal, the second cavity space is provided at a position closer to the outer periphery of the plate-like body than the concave portion of the mold, thereby forming the recess and the plate-like body. By simultaneously injecting the resin material into the first cavity space and injecting the resin material into the second cavity space, the base and the frame can be easily formed integrally with the plate-like body.
[0027]
As the resin molding die in the present invention, a normal metal die can be generally employed. Inexpensive molds such as heat-resistant resin molds can be adopted by controlling the number of production lots and the injection pressure of the resin material. In the above example, the resin molding die is composed of three mold parts. However, it is sufficient that the resin molding mold is composed of at least two mold parts, and according to structural requirements such as a sprue, a runner, and a gate, It can be determined as appropriate.
[0028]
For example, as shown in FIG. 1 (b), one mold portion consisting of an upper mold 5 and an intermediate mold 6 joined so as to form a sprue, a runner, and a gate (resin flow path 8), and a plate-like body 1 For resin molding, a mold part composed of a backup member 17 (preferably having a packing on the contact surface with the plate-like body) for preventing deflection and breakage due to the injection pressure of the resin material is used as two mold parts. It is preferable to configure the mold. This is because it is sandwiched between only the parts of the plate-like body by means of two mold portions (portions and backup member 17 of the intermediate mold 6 of the upper die 5 and the intermediate type 6), the breakage of the plate-like body This is because it can be prevented.
[0029]
There is no particular limitation on the shape of the resin flow path outlet. After the resin material is solidified, the molded base and the resin flow path are surely separated, and the resin flow path outlet diameter is not required to finish the molding surface. Is preferably 2 mm or less.
[0030]
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 a substantially stepped shape as in the above example, but the recessed portion is provided with a deep portion and a shallow portion, that is, a portion where the height of the pedestal to be formed is high and a portion where the height is low. It is preferable to provide the recessed portion with such a depth that can be formed so that post-finishing is unnecessary for the molded pedestal.
[0031]
The reason why post-finishing is unnecessary is as follows. In general, at the outlet of the resin flow path, after resin molding, a small protrusion is formed by protruding and solidifying the resin material. If this 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 attached, the adhesion between the two becomes poor when the plate-like body is attached to the window opening. Therefore, it is necessary to remove the small protrusions, but a complicated process is increased. Therefore, if the small protrusion is formed one step below the mounting member for the pedestal to be molded, the post-finishing described above is unnecessary.
[0032]
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. In some cases, post-finishing can be made unnecessary by providing a resin channel outlet on the side surface of the recess, but it is preferable to provide the resin channel outlet in the shallow portion in view of the fluidity of the resin.
[0033]
Even if the mounting member is responsible for fixing (fixing) the plate-like body to the window opening, it is interposed between the plate-like body and the window opening, and the window opening of the plate-like body It may be responsible for positioning and temporary fixing until a sealant such as urethane that is fixed to the base (fixed) is solidified. In the former case, a sealant for preventing water leakage is interposed between the plate-like body and the window opening portion on the outer peripheral side of the plate-like body as required. On the other hand, in the latter case, a sealant such as urethane itself functions as a sealant for preventing water leakage.
[0034]
【Example】
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 producing a window plate with a mounting member in the present invention. The resin molding die 40 has an upper mold 5, an intermediate mold 6, and a lower mold 7, and a resin flow path 8 including a sprue, a runner, and a gate is formed between the upper mold 5 and the intermediate mold 6. ing. A recess 22 is provided on the lower surface of the intermediate mold 6. When the peripheral edge of the plate-like body 1 made of a curved single plate glass plate is sandwiched between the intermediate mold 6 and the lower mold 7, the recess 22 and the plate A cavity space is formed by 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 placed by the inner wall of the intermediate mold 6 , the inner wall of the lower mold 7, and the peripheral portion of the plate-shaped body 1. A second cavity space 31 is formed so as to go around.
[0035]
The portion of the lower plate 7 that is in contact with the plate-like body 1 is provided with a packing 10 made of urethane rubber that holds the plate-like body 1 in a flexible manner, and the plate-like body of the intermediate die 6. An absorbing member 9 made of fluororubber capable of absorbing the deviation of the curvature of the plate-like body 1 is provided at a portion in contact with 1.
[0036]
The concave portion 22 has a substantially stepped vertical cross section, and has a deep portion 22a and a shallow portion 22b. A mounting member 21 is attached to a deep portion of the recess 22. Also, the resin flow path outlet 11 is provided in the shallow portion, and a 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 31 of the intermediate mold 6 and is injected from the resin flow path outlet 11 and at the same time from the second resin flow path outlet 12. Resin material is injected into the second cavity space 31.
[0037]
In this way, the mounting member is mounted in the deep portion of the concave portion 22, the plate-like body 1 is sandwiched between the intermediate mold 6 and the lower mold 7, the resin material is injected into the cavity space and solidified, and then the intermediate mold 6 By releasing the lower mold 7 and tearing the resin at the resin flow path outlet 11, the plate-like body was taken out of the mold, and the base of the mounting member was integrally formed with the mounting member into the plate-like body. At this time, even if small protrusions remain on the lower stage of the pedestal having a substantially stepped cross section due to tearing of the resin, post-finishing to remove is unnecessary.
[0038]
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 of the mounting member and the base are more strongly integrated, which is preferable.
[0039]
FIG. 3 is a schematic perspective view showing an example of a plate-like body with a mounting member manufactured as described above, and FIG. 4 is a cross-sectional view taken along line AA of FIG. A frame 3 made of synthetic resin is integrally formed on the peripheral edge of the plate-like body 1, and is integrally formed on a base 2 of a mounting member integrally formed on one side of the plate-like body 1 on the inner peripheral side thereof. The mounting member 21 is formed.
[0040]
When the plate-like body with the mounting member thus obtained is used as an automobile fixing window, the plate-like body 1 is formed by inserting the mounting member 21 into a positioning hole provided at a predetermined position of the automobile window opening. It can be positioned and held in the window opening. In this example, the small protrusion 29 remains on the lower stage of the pedestal 2 having a substantially stepped cross section, but the remaining position of the small protrusion 29 is a position that does not affect the positioning of the plate-like body. Furthermore, a sealant 4 for preventing water leakage is laminated between the frame 3 on the surface of the plate-like body 1 and the mount 2 of the attachment member, and the plate-like body with the attachment member is attached to the window opening.
[0041]
When the mounting member 21 itself can fix the plate-like body 1 to the window opening, a butyl sealant or the like is used as a water leaking sealant, but the fixing force of the mounting member 21 is poor. For example, a urethane sealant is used as a water leak sealant. In the latter case, the mounting member 21 has a function of temporarily holding the plate-like body 1 at a predetermined position of the window opening until the urethane sealant is solidified and the plate-like body is fixed to the window opening. . In this embodiment, a resin molded product made of polyacetal is used as such a mounting member, but the present invention is not limited to this.
[0042]
【The invention's effect】
According to the present invention, since the pedestal of the mounting member is integrally molded from the end surface of the plate-like body to one side on the inner peripheral side by a predetermined distance, the leakage prevention for applying the plate-like body to the window opening is applied. The sealant can be located on the outer peripheral side of the pedestal, thereby preventing an increase in the number of parts and extra steps. In particular, when the frame body is integrally formed at the periphery of the plate-like body at the same time, the conventional process of removing the bridge-like portion of the resin can be eliminated. In addition, by eliminating this removal step, the plate-like body is not damaged.
[0043]
Also, a mold cavity space is formed so as to provide a step in the shape of the pedestal to be molded, and a resin material is injected into the cavity space from a portion corresponding to a low step of the pedestal, thereby completing the molded pedestal. There is no need to remove the small protrusions from the resin.
[0044]
Furthermore, according to the present invention, since there is no restriction on how to attach the mounting member to the mold, the direction in which the mounting member extends is not limited to the normal direction of the plate-like body, and the window opening or the plate-like body. Depending on the design, it can be directed in an appropriate direction. Depending on the purpose of temporary fixing, permanent fixing, etc., or the size of the plate-like body, the required number of attachment members can be attached to the plate-like body as many as necessary, which is The manufacturing method of the plate-shaped body with the member for attachment which increased the freedom degree can be obtained.
