DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide used for integrally attaching a belt-like member to a molding body. Furthermore, the invention relates to a mold provided with such a guide.

[0002]

BACKGROUND OF THE INVENTION Vehicle seats, office or home chairs,
In an article such as a mattress having a cushioning core material formed of a molded article of a foamable resin material and a flexible coating material such as a cloth or leather covering the surface of the core material, the coating material is coated with a core material. In order to firmly and firmly adhere to the material,
It is known to use a face-to-face engagement type fastener member (so-called hook-and-loop fastener) in which a plurality of engagement elements are arranged on one surface of a base (for example, see Japanese Patent Application Laid-Open No. 9-224720).

[0003] In particular, for articles such as seats and chairs, it is desired to provide a high level of comfort to the user. There is a tendency to use a fastener member having an elongated band shape that can be arranged in a groove provided on the surface of a core material along the same. As an example, FIG. 10 shows a state in which an elongated belt-shaped fastener member 5 is installed in a groove 4 provided on a surface of a core material 3 along a seam 2 or the like of a covering material 1 in a vehicle seat. In order to fixedly install such a band-shaped fastener member at a desired position on the surface of the core material in a state where the engagement element is exposed, the fastener member is arranged as an insert in a mold of the core material that is a main body of molding, An insert molding method for fixing the fastener member to the core at the same time as the molding of the core is advantageously implemented. For example, Japanese Patent No. 2704859 discloses a guide for supporting a fastener member in a core material mold in such an insert molding method.

[0004] The guide described in this publication is provided with a single groove capable of removably accommodating the fastener member in a substantially extended state (that is, a state in which the fastener member is not wound or folded). The groove is formed by the bottom wall of the guide and a pair of side walls of the guide that are integrally erected from the bottom wall along both edges of the bottom wall extending in the longitudinal direction. Further, in this guide, partitions are provided near the longitudinal ends of the groove to prevent the liquid foaming material from entering the inside of the groove when the core material is formed.

The guide is fixed at a desired position on the molding surface by bringing its bottom wall into contact with the molding surface of the core material mold. The fastener member is housed in the groove with the engagement element inserted into the space between the pair of side walls and the pair of partition walls of the guide. In this state, if the liquid foaming material is injected into the molding cavity of the mold to form the core, the fastener member is fixedly attached to a predetermined position on the surface of the core.

[0006] The main mold used in such a molding process generally has an upper mold and a lower mold that are rotatably connected to each other via a shaft in order to facilitate opening and closing operations of the mold. Having. In this case, with the upper mold and the lower mold open, the worker attaches the fastener member to a guide fixed to one or both of the molding surfaces, and then rotates the upper mold and the lower mold. Close to the formula and mold the molding subject. After the molding, the upper mold and the lower mold are pivotally opened, and the molding main body adhered to one of the molds is taken out.

[0007]

The above-mentioned conventional guide used for integrally attaching the strip-shaped fastener member to the molding main body generally has a flat outer surface of the bottom wall and a flat outer surface of each side wall. It has outer shapes orthogonal to each other. Therefore, when the bottom wall is brought into contact with the molding surface of the mold and the guide is fixed to the molding surface, the outer surface of each side wall of the guide is arranged orthogonal to the molding surface of the mold. When the forming main body is formed using such a guide, a recess having a substantially rectangular cross section having a shape corresponding to the outer shape of the guide is formed on the surface of the forming main body, and a fastener member is fixedly attached to the bottom surface of the recess. .

In the above configuration, as the mold is opened after the molding main body is formed, there is a case where the molding main body attached to one of the upper mold and the lower mold operates to separate from the guide fixed to the other mold. is there. Here, if the guide is fixed to the molding surface with its side wall disposed substantially parallel to the rotation axis of the upper mold and the lower mold, when the molding main body separates from the guide with the opening operation of the mold. In some cases, the side wall located outside the guide when viewed from the rotation axis is caught by the forming main body, and as a result, the forming main body may be damaged such as a crack. The damage due to the so-called mold release resistance is more likely to occur as the distance between the rotation axis of the mold and the guide on the molding surface becomes smaller. Also,
Not limited to the above-described substantially parallel arrangement, as long as the side wall of the guide is arranged so as to intersect with a plane perpendicular to the rotation axis, there is a possibility of damage due to mold release resistance, although the degree varies.

[0009] Further, as the mold is opened after the molding main body is formed, the molding main body may be left in the mold to which the guide is fixed. In this case, when the molding main body is manually removed from the mold, one or both side walls of the guide may be caught by the molding main body, and as a result, the molding main body may be similarly damaged such as a crack. In any case, such damage due to the mold release resistance is caused by a concave portion having a substantially rectangular cross section formed in the molding main body and a bottom surface corresponding to the top surface of the outer side wall of the guide and a side surface corresponding to the outer surface of the same side wall. Tend to be caused by stress concentration at the intersections of.

An object of the present invention is to provide a guide used for integrally attaching a belt-like member to a molding main body, which can be easily removed without damaging the molding main body after molding of the molding main body. It is in. Another object of the present invention is to provide a molding die having a guide for integrally attaching a belt-shaped member to a molding main body, wherein the molding die can be easily removed without damaging the molding main body after molding of the molding main body. Is to do.

[0011]

Means for Solving the Problems In order to achieve the above object, the present invention according to claim 1 comprises a bottom wall, a pair of side walls erected on the bottom wall, and a bottom wall and a pair of side walls. And a guide capable of removably receiving the band-shaped member in the groove, the outer surface of at least one of the side walls,
A guide is provided which extends in a direction crossing the outer surface of the bottom wall at an acute angle.

According to a second aspect of the present invention, there is provided the guide according to the first aspect, wherein at least a part of the outer surface of at least one of the side walls has a convex curved surface.

According to a third aspect of the present invention, there is provided a guide fixedly provided on a molding surface, the guide having a pair of side walls erected on the molding surface and a groove formed between the pair of side walls. Wherein the outer surface of at least one of the side walls of the guide extends in a direction intersecting the molding surface at an obtuse angle. .

The fastener member 12 is held in a predetermined posture by a frictional force in a state in which the fastener member 12 is fitted in a. As a result, when the main body of the molding is formed while the fastener member 12 is supported by the guide 10, the infiltration of the liquid material into the second portion 26b of the groove 26 is prevented.

The guide 10 having the above structure is integrally formed by cutting a metal rod-shaped material such as aluminum, an aluminum alloy, and iron. In this case, for example, the groove 26 can be cut in accordance with a predetermined program by using a tea throw cutter (product name) mounted on an NC milling machine. However guide 10
Can be produced by various other known methods.

The fastener member 12 as an example of a band-shaped member accommodated in the guide 10 has a

A slit 44 extending in the transverse direction is formed in the lower plate portion 34 of each box-shaped portion 28 at substantially the center in the longitudinal direction. Further, a rib 46 extending in the longitudinal direction across the slit 44 is provided on the lower plate portion 34 so as to protrude over the entire base 14. Two thin plate-like anchors 48 are formed on the ribs 46 and extend substantially parallel to the lower plate portion 34, two for each box-shaped portion 28. The rib 46 and the anchor 48
It is a connecting element embedded in the forming main body through an insert forming process described later, and constitutes a mechanical connecting portion of the fastener member 12 to the forming main body.

The fastener member 1 having such a configuration
2, the base 14 can be bent relatively easily in the horizontal direction, that is, in a direction parallel to the one surface 16 as a whole, by the stress dispersing action of each box-shaped portion 28 having a hollow structure. Further, the hinge portion of each thin connecting portion 30 allows the base portion 14 to bend relatively easily in the vertical direction, that is, the direction orthogonal to the one surface 16 as a whole. As described above, the fastener member 12 can easily bend the base portion 14 in both the horizontal direction and the vertical direction, so that the base portion 14 can be three-dimensionally accurately positioned on a desired surface portion of an object having various three-dimensional surfaces. Can be installed to follow. Preferably, the fastener member 12 is integrally formed from a resin material such as nylon, polyethylene, or polypropylene.

In the guide 10, the height of the inner surfaces 22b, 24b of the side walls 22, 24 from the support surfaces 22c, 24c to the upper end is equal to or slightly equal to the thickness of the base 14 of the fastener member 12. It is desirable that it is larger. According to this configuration, the base 14 of the fastener member 12

It can be easily confirmed visually or tactilely that it is fitted in contact with 24c. However, guide 10
If each of the side walls 22 and 24 protrudes too much from the lower plate portion 34 of the base portion 14 of the fastener member 12, there is a concern that the smooth flow of the molten material is hindered during molding of a molding main body, which will be described later.
Therefore, the difference between the height of each of the side walls 22 and 24 of the guide 10 from each of the support surfaces 22c and 24c and the thickness of the base 14 of the fastener member 12 is preferably about 1 mm.

FIG. 3 shows a molding die 50 according to an embodiment of the present invention provided with the guide 10 having the above configuration. The molding die 50 has, for example, a mold structure for molding a core material (cushion) of a seat portion of a vehicle seat from a foamable resin material. However, the mold according to the present invention is not limited to the mold having the illustrated configuration, and can be applied to molds for molding other various molding bodies.

The molding die 50 includes an upper die 54 and a lower die 56 which are rotatably connected to each other via a shaft 52. The upper mold 54 and the lower mold 56 are provided with molding surfaces 58 and 60, respectively, for molding a core material which is a molding main body. The three guides 10 are provided at predetermined positions in the molding surface 60 of the lower die 56. Each guide 10 is fixed by using a known fixing means such as a putty, a bolt, and a magnet by bringing the outer surface 20a of the bottom wall 20 into contact with the molding surface 60 of the lower mold 56 (FIG. 2). In particular, if the guide 10 is fixed to the lower mold 56 using magnetic means, there is an advantage that the operation of housing the fastener member 12 can be performed outside the molding die 50.

When the guide 10 is fixed to the forming surface 60 in this manner, as shown in FIG. 2, the outer surface 22a of one of the side walls 22 of the guide 10 is arranged so as to intersect with the forming surface 60 at an obtuse angle β. The outer surface 24a of the other side wall 24 is
It is arranged orthogonal to 0. The groove 26 of the guide 10
Opens into a molding cavity formed between the molding surface 58 of the upper mold 54 and the molding surface 60 of the lower mold 56.

As shown in FIG. 4, in the molding die 50, one guide 10 on the molding surface 60 moves the side walls 22, 24 with respect to the rotating shaft 52 of the upper die 54 and the lower die 56. The other two guides 10 are arranged so as to be substantially parallel, and their two side walls 22 and 24 are arranged obliquely with respect to the rotation shaft 52. Here, each guide 10 is oriented on the molding surface 60 such that the side wall 22 having the inclined outer surface 22 a is located outside the respective guide 10 when viewed from the rotation shaft 52.

Next, an insert molding step for molding the core material 62, which is a molding main body, by using the molding die 50 having the above configuration will be described. First, the worker attaches the fastener member 12 to each of the three guides 10 fixed to the molding surface 60 with the upper mold 54 and the lower mold 56 opened. At this time, the plurality of engagement elements 18 of each fastener member 12 are accommodated in the second portion 26b of the groove 26 of the corresponding guide 10, and the base 1
4 is the inner surfaces 22 of the side walls 22 and 24 of the guide 10
b, 24b, and is housed in the first portion 26a of the groove 26.

Subsequently, the upper mold 54 and the lower mold 56 are pivotally closed, and the upper mold 54 and the lower mold 56 are heated and maintained at a predetermined temperature. A molten resin material (for example, a foamable liquid resin material such as polyurethane) is supplied to the cavity. Then, the upper mold 54 and the lower mold 5
6 is cooled to room temperature to solidify the molten resin material, and a core material, which is a molding main body, is formed. When the molding of the core material is completed, the fastener member 12 is fixedly connected to a predetermined position on the surface of the core material with the plurality of engagement elements 18 exposed.
FIG. 5A shows the core member 62 thus formed in the mold 50 together with the guide 10 and the fastener member 12.

Next, when the upper mold 54 and the lower mold 56 are pivotally opened, the core material 62 tends to maintain a state of being attached to the molding surfaces 58, 60 of one of the molds 54, 56. Here, when the core material 62 adheres to the molding surface 58 of the upper mold 54 and moves in a direction away from the lower mold 56 together with the upper mold 54, the three fastener members integrally attached to the core material 62 12 is a guide 1 corresponding to the movement of the core 62.
Depart from 0. At this time, in the molding die 50, since each guide 10 is oriented on the molding surface 60 so that the side wall 22 having the inclined outer surface 22a faces outward when viewed from the rotation shaft 52, the rotation shaft 52 is While the upper mold 54 and the core 62 move as the center, the caught between the outer side wall 22 of each guide 10 and the core 62 is effectively reduced or avoided (see FIG. 5B). As a result, when the core member 62 is detached from the molding die 50, it is possible to prevent the fastener member mounting portion of the core member 62 from being damaged such as a crack. In addition,
The core 62 attached to the molding surface 58 of the upper mold 54 can be easily detached from the upper mold 54 by manual operation.

FIG. 6 is an enlarged view showing the fastener member mounting portion of the core member 62 in which the fastener member 12 is integrally mounted at a predetermined position after the above-described insert molding step. The core member 62 has a concave portion 64 formed at a predetermined position on the surface 62a so as to correspond to the guide 10, and the fastener member 12 is fixedly attached to a bottom surface 64a of the concave portion 64. The fastener member 12 is provided on one surface 16 of the base 14.
The plurality of engaging elements 18 formed in the base member 14 are disposed in the recess 64 so as to be exposed, and the ribs 46 and the plurality of anchors 48 formed on the other surface of the base 14 are embedded in the core member 62.

The concave portion 64 formed in the core member 62 corresponds to one side surface 64b formed corresponding to the outer surface 22a of one side wall 22 of the guide 10, and corresponds to the outer surface 24a of the other side wall 24 of the guide 10. And the other side surface 64c formed. One side surface 64b of the concave portion 64 intersects the surface 62a of the core member 62 and the bottom surface 64a of the concave portion 64 at an obtuse angle, and the other side surface 64c forms the surface 62a of the core member 62 and the concave portion 64a.
Is substantially orthogonal to the bottom surface 64a of the second member. In the concave portion 64 having such a shape, stress concentration due to mold release resistance at the intersection 66 between the bottom surface 64a of the concave portion 64 and one side surface 64b when the guide 10 is separated from the core member 62 is effective. (FIG. 5B), so that damage such as a crack is unlikely to occur at the intersection portion 66.

As described above, according to the guide 10 and the molding die 50 having the same, the guide 10 is formed in the molding die 50 so that the side wall 22 having the inclined outer surface 22 a is viewed from the rotation shaft 52. By arranging it so as to be located on the outside, the core material 62, which is a molding main body, is
Can be easily removed from the molding die 50 without damaging the fastener member mounting portion.

The outer surface 20a of the bottom wall 20 of the guide 10
The preferred intersection angle α between the outer surface 22a of the side wall 22 and
Although it depends on the distance from the rotation axis 52 of the molding die 50 to the guide 10 and the arrangement angle of the side wall 22 of the guide 10 with respect to the rotation axis 52, for example, the range is 1 ° to 10 °. Further, as shown in FIG. 7, a convex curved surface 68 can be formed on at least a part of the outer surface 22a of the side wall 22 of the guide 10 (a boundary portion between the outer surface 22a and the top surface 22d in the figure). According to such a configuration, the above-described core material 62
Intersection 66 between the bottom surface 64a and the side surface 64b of the concave portion 64
Is formed into a curved surface, so that stress concentration on the intersection portion 66 is reduced more effectively. Further, as shown in FIG. 8, the entire outer surface 22a of the side wall 22 of the guide 10 is formed as a convex curved surface having a radius of curvature corresponding to the distance from the rotation shaft 52 of the molding die 50 to the outer surface 22a of the side wall 22. Can also.

By the way, in the above-described insert molding step, when the upper mold 54 and the lower mold 56 are opened after the molding of the core material 62, the core material 62 is left in a state of being attached to the molding surface 60 of the lower mold 56. There are cases. In this case, then
The core material 62 is detached from the lower mold 56 manually, but the detachment direction is different from the above-described case specified by the rotation shaft 52 in various directions that can be freely selected by the operator. Become. In such a case, in order to prevent the core member 62 from being damaged by the side walls 22 and 24 of the guide 10 at the time of detachment, the outer surface 2 of the other side wall 24 of the guide 10 is required.
4a is likewise advantageously formed as a surface extending in a direction which intersects the outer surface 20a of the bottom wall 20 at an acute angle. In addition, both end surfaces in the longitudinal direction of the guide 10 may be formed as similar inclined surfaces.

Further, in the above-described configuration, FIG.
As shown in (b), when the core member 62 separates from the guide 10, the side wall 24 located inside the guide 10 as viewed from the rotation shaft 52 is positioned inside the recess 64 of the core member 62. In particular, there is a tendency to interfere with the fastener member mounting portion. In order to avoid such interference, for example, as shown in FIG. 9, it is advantageous to form the entire guide 10 in a shape inclined in one direction. In this configuration, the bottom wall 20 of the guide 10 is
Has an outer surface 20a and an inner surface 20b extending in directions intersecting at an acute angle with each other, and one side wall 22 has an outer surface 22a intersecting the outer surface 20a of the bottom wall 20 at an acute angle and a step perpendicular to the inner surface 20b of the bottom wall 20. The other side wall 24 has an outer surface 24a intersecting the outer surface 20a of the bottom wall 20 at an obtuse angle, and a stepped inner surface 24b orthogonal to the inner surface 20b of the bottom wall 20. The guide 10 is used for the molding die 5 described above.
When it is installed at zero, the side wall 22 having the outer surface 22 a inclined at an acute angle may be oriented on the molding surface 60 so that the side wall 22 is located outside the guide 10 when viewed from the rotation shaft 52.

The molding die according to the present invention is not limited to the above-described configuration, and may have a configuration in which, for example, a guide having the same configuration as the guide 10 is integrally formed on the molding surface. Such a mold has a guide fixedly provided on a molding surface and a guide having a pair of side walls provided upright on the molding surface and a groove formed between the side walls, and a band-shaped member is provided in the groove of the guide. A mold adapted to be removably accommodated, wherein an outer surface of at least one side wall of the guide is provided.
It extends in a direction intersecting the molding surface at an obtuse angle.

According to this aspect, a conventional guide having an outer surface of the bottom wall and an outer surface of each side wall orthogonal to each other is composed of a putty or the like between the bottom wall and the molding surface of the mold. By integrally fixing to the molding surface with the wedge-shaped member interposed, a molding die according to the present invention having a guide having substantially the same configuration as the configuration shown in FIG. 9 can be provided.
