Detailed Description
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
The door hinge device for an automobile includes an upper door hinge 1U for pivotally supporting an upper portion of a door on a vehicle body and a lower door hinge 1L for pivotally supporting a lower portion of the door on the vehicle body. A swing door supported openably and closably on a side surface of a vehicle body is pivotally supported on the vehicle body by an upper door hinge 1U and a lower door hinge 1L.
Fig. 1 (a), 2 (a), 3, 5 (a), and 6 (a) show an upper door hinge 1U, and fig. 1 (b), 2 (b), 4, 5 (b), and 6 (b) show a lower door hinge 1L. Fig. 7 is an enlarged longitudinal sectional view of a main portion of the upper door hinge 1U, and fig. 8 and 9 are enlarged longitudinal sectional views of a main portion of the lower door hinge 1L.
The upper door hinge 1U and the lower door hinge 1L of the present embodiment are for supporting a left rear door (hereinafter referred to as "door") D to be openable and closable with respect to a left rear door of the vehicle body B. The upper door hinge and the lower door hinge for the right rear door, which openably and closably support the right rear door to the vehicle body, are formed in a left-right line-symmetrical shape with respect to the upper door hinge 1U and the lower door hinge 1L for the left rear door.
The door D assembled to the vehicle body B by the upper door hinge 1U and the lower door hinge 1L of the present embodiment can be detached from the vehicle body B after being painted together with the vehicle body B in the vehicle body assembling step, and after being detached, various safety devices, electric devices, and the like can be attached in the assembling step, and then can be assembled to the vehicle body B again in the vehicle body assembling step.
In the description of the door hinge device for the automobile, first, the respective components of the upper door hinge 1U are described, and then the respective components of the lower door hinge 1L are described.
The upper door hinge 1U and the lower door hinge 1L have different external shapes depending on the vehicle body structure and the door structure to be mounted, but have the same basic functions as the respective elements. Therefore, the reference numerals for the respective components of the upper door hinge 1U and the lower door hinge 1L are the same as those for the components having the same functions, and in order to distinguish the upper door hinge 1U from the lower door hinge 1L, the upper door hinge 1U is added with "U" after the arabic numerals, and the lower door hinge 1L is added with "L" after the arabic numerals.
The upper door hinge 1U includes: a door-side base member 2U fixed to the door D side; a vehicle-body-side base member 3U fixed to the vehicle body B side; a hinge shaft 4U which is oriented in the vertical direction, an upper half portion of the hinge shaft 4U being assembled to the door-side base member 2U so as to be rotatable with respect to the door-side base member 2U and substantially not to be pulled out in the axial direction, a lower half portion of the hinge shaft 4U being assembled to the vehicle-body-side base member 3U so as to be non-rotatable with respect to the vehicle-body-side base member 3U and detachably attachable in the axial direction, the hinge shaft 4U being capable of connecting the door-side base member 2U and the vehicle-body-side base member 3U to each other so as to be rotatable with respect to each other; and a screw coupling body 5U which is detachably screw-coupled to an external screw portion 41U provided at a lower portion of the hinge shaft 4U from below, wherein the upper door hinge 1U has a function of attaching and detaching: by detaching the screw-coupled body 5U from the male screw portion 41U of the hinge shaft 4U from below, the door-side base member 2U can be detached from the vehicle-body-side base member 3U in a state where the vehicle-body-side base member 3U is fixed to the vehicle body B.
As shown in fig. 3 and 7, the hinge shaft 4U is made of steel so as to be attachable and detachable, and is integrally formed with the following structure: a male screw portion 41U in the lower half portion thereof, which is inserted into a later-described shaft hole 32U of the door-side base member 3 so as not to be rotatable, and to which the screw-coupled body 5U is detachably screw-coupled; a rotating portion 42U provided in the upper half portion and inserted into a later-described shaft hole 22U of the door-side base member 2U in a rotatable manner; a diameter-expanding conical portion 43U provided between the male thread portion 41U and the rotating portion 42U; and a small diameter portion 44U provided at an upper end of the rotating portion 42U. The conical surface of the diameter-expanding conical portion 43U facing downward is engraved with serrations 45U. After the hinge shaft 4U is inserted into the shaft hole 22U of the door-side base member 2U, the small diameter portion 44U is caulked so that the hinge shaft 4U cannot be pulled out from the shaft hole 22U.
The screw-coupled body 5U is formed of steel and integrally formed in the following configuration: a head 51U, which is hexagonal, at the lower half; a cylindrical portion 53U having an inner threaded portion 52U formed on an inner peripheral surface thereof and capable of being screwed with the outer threaded portion 41U of the hinge shaft 4U; and a conical portion 54U which is located between the head portion 51U and the cylindrical portion 53U and which gradually decreases in diameter as it goes upward.
The door-side base member 2U is manufactured by casting an aluminum alloy as a raw material in order to reduce the weight and improve the production efficiency, and is integrally formed with the following structure: a base portion 21U fixed to a mounting surface (vertical surface) of the door D by bolts (not shown); and a bearing portion 23U having a vertical shaft hole 22U formed therethrough, the shaft hole 22U allowing the rotation portion 42U of the hinge shaft 4U to be inserted so as to be relatively rotatable.
Preferably, in the case where the door D is made of steel, the surface of the door side base member 2U is subjected to electrodeposition coating treatment in order to prevent dissimilar metal contact corrosion from occurring on the contact surface with the door D, and in the case where the door D is made of aluminum, the surface of the door side base member 2U is subjected to corrosion-resistant aluminum treatment (anodic oxidation treatment) as dust-proof because it is not necessary to prevent dissimilar metal contact corrosion.
The base portion 21U of the door-side base member 2U is formed with attachment holes 24U, 24U penetrating in the front-rear direction, i.e., in the direction orthogonal to the shaft hole 22U, and bolts, not shown, for fixing the base portion 21U to the door D can be inserted into the attachment holes 24U, 24U from the front.
A stopper portion 25U is provided on the outer periphery of the bearing portion 23U of the door side base member 2U, and the stopper portion 25U protrudes to the outside of the outer peripheral surface to regulate the fully open position of the door D. The stopper portion 25U abuts against the abutment surface 34U of the vehicle-body-side base member 3U to regulate the fully open position of the door D.
As can be understood from fig. 3 and 7, in order to allow the rotary portion 42U of the hinge shaft 4U to smoothly rotate in the shaft hole 22U, the upper flanged bush 6U is fitted into the shaft hole 22U of the door side base member 2U so as to be substantially non-rotatable from above, and the lower flanged bush 7U is fitted into the shaft hole 22U of the door side base member 2U so as to be substantially non-rotatable from below.
The small diameter portion 44U of the hinge shaft 4U protruding upward from the bushing 6U fitted into the upper side of the shaft hole 22U is swaged so as not to be pulled out from the shaft hole 22U. In this case, since the flange portion 61U is formed in advance in the upper bushing 6U, it is not necessary to perform flange processing on the bushing 6U at the time of caulking the hinge shaft 4U.
Preferably, a washer 8U is present between the caulking portion and the flange portion 61U of the upper bushing 6U.
Thus, the rotation portion 42U of the hinge shaft 4U is rotatably assembled to the shaft hole 22U of the door-side base member 2U through the bushes 6U, 7U so as not to be pulled out in the axial direction. Further, the inner peripheral surfaces of the bushings 6U and 7U are surface-treated so that the rotation portion 42U of the hinge shaft 4U can smoothly rotate without rattling.
The vehicle-body-side base member 3U is manufactured by casting an aluminum alloy as a raw material in order to reduce the weight and improve the production efficiency, similarly to the door-side base member 2U, and integrally formed with the following structure: a base portion 31U fixed to a mounting surface (vertical surface) of the vehicle body B by bolts (not shown); and a bearing portion 33U, which is located below the bearing portion 23U of the door-side base member 2U and has a vertical shaft hole 32U into which the male screw portion 41U of the hinge shaft 4U is inserted.
Preferably, in the case where the vehicle body B is made of steel, the surface of the vehicle-body-side base member 3U is subjected to electrodeposition coating treatment in order to prevent dissimilar metal contact corrosion from occurring at the contact surface with the vehicle body B, and in the case where the vehicle body B is made of aluminum, the surface of the vehicle-body-side base member 3U is subjected to alumite treatment (anodic oxidation treatment) because it is not necessary to prevent dissimilar metal contact corrosion.
The base portion 31U is formed with attachment holes 35U, 35U penetrating in the left-right direction, that is, in the direction orthogonal to the shaft hole 32U, and bolts, not shown, for fixing the base portion 31U to the vehicle body B can be inserted into the attachment holes 35U, 35U from the vehicle exterior side.
The male screw portion 41U of the hinge shaft 4U is inserted into the shaft hole 32U of the vehicle-body-side base member 3U from above, the cylindrical portion 53U of the screw-coupled body 5U is inserted into the shaft hole 32U of the vehicle-body-side base member 3U from below, and in this state, the female screw portion 52U of the screw-coupled body 5U is screwed to the male screw portion 41U of the hinge shaft 4U. Thereby, the male screw portion 41U of the hinge shaft 4U is fixed to the shaft hole 32U of the vehicle body side base member 3U so as not to rotate. Further, by detaching the screw-coupled body 5U from the male screw portion 41U of the hinge shaft 4U from below and displacing the door D upward, the door D can be detached from the vehicle body B in a state where the vehicle body side base member 3U is fixed to the vehicle body B and the door side base member 2U is fixed to the door D.
The reason why the screw-coupled body 5U is attached and detached to and from the upper door hinge 1U from below is that a space for attaching and detaching the screw-coupled body 5U can be easily secured in the door D having a curved shape in which the upper and lower center portions bulge outward in a front view.
A tapered portion 36U is provided at an entrance on the upper side of the shaft hole 32U, the tapered portion 36U is abutted by the serrations 45U of the diameter-expanding conical portion 43U provided on the hinge shaft 4U, and a tapered portion 37U is provided at an entrance on the lower side of the shaft hole 32U, and the tapered portion 37U is abutted by the conical portion 54U of the screw coupling body 5U.
The screw-coupled body 5U is screw-coupled to the male screw portion 41U of the hinge shaft 4U, and the head 51U is tightened with a tool, whereby the conical portion 54U of the screw-coupled body 5U is fitted into the conical portion 37U below the shaft hole 32U of the vehicle-body-side base member 3U from below by a wedge action. Thereby, the male screw portion 41U of the lower half of the hinge shaft 4U can be firmly fixed to the shaft hole 32U of the vehicle-body-side base member 3U. Further, by tightening the screw-coupled body 5U, the serrations 45U of the diameter-enlarged conical portion 43U of the hinge shaft 4U are also fitted into the upper conical portion 36U of the shaft hole 32U from above by a wedge action. Thereby, the male screw portion 41U of the lower half portion of the hinge shaft 4U can be more firmly fixed to the shaft hole 32U of the vehicle-body-side base member 3U.
In the present embodiment, the taper angle of the conical portion 54U of the screw-coupled body 5U (the same angle as θ 1 shown in fig. 9) is set to 26 degrees, the taper angle of the diameter-enlarged conical portion 43U of the hinge shaft 4U (the same angle as θ 2 shown in fig. 9) is set to 28 degrees, and the taper angles of the upper and lower tapered portions 36U and 37U of the shaft hole 32U (the same angle as θ 3 shown in fig. 9) are set to 30 degrees larger than θ 1 and θ 2. That is, the angle of each portion is set to a relationship of θ 1 < θ 2 < θ 3. By setting the angle in this manner, the conical portion 54U of the screw-coupled body 5U can be more reliably fitted into the lower tapered portion 37U of the shaft hole 32U of the vehicle-body-side base member 3U, and the serrations 45U of the diameter-enlarged conical portion 43U of the hinge shaft 4U can be more reliably fitted into the upper tapered portion 36U of the shaft hole 32U of the vehicle-body-side base member 3U.
Next, each constituent element of the lower door hinge 1L will be described. The hinge shaft 4L and the screw combination 5L of the lower door hinge 1L and the hinge shaft 4U and the screw combination 5U of the upper door hinge 1U are vertically symmetrical, and therefore, the above-described members will be described simply.
The lower door hinge 1L includes: a door-side base member 2L fixed to the door D side; a vehicle-body-side base member 3L fixed to the vehicle body B side; a hinge shaft 4L that is oriented in the vertical direction, a lower half portion of the hinge shaft 4L being assembled to the vehicle-side base member 3L so as to be rotatable with respect to the vehicle-side base member 3L and substantially not to be pulled out in the axial direction, an upper half portion of the hinge shaft 4L being assembled to the door-side base member 2L so as to be non-rotatable with respect to the door-side base member 2L and detachably attachable in the axial direction, and the door-side base member 2L and the vehicle-side base member 3L being connected to each other so as to be rotatable; and a screw coupling body 5L that is detachably screw-coupled to a male screw portion 41L provided in an upper half portion of the hinge shaft 4L from above, and the lower door hinge 1L has a function of attaching and detaching: the door-side base member 2L can be detached from the vehicle-body-side base member 3L by detaching the screw-coupled body 5L from the male screw portion 41L of the hinge shaft 4L from above.
The reason why the screw-coupled body 5L is attached and detached from above in the lower door hinge 1L is that a space for attaching and detaching the screw-coupled body 5L can be easily secured for the door D having a curved shape as described above.
As shown in fig. 4, 8 and 9, the hinge shaft 4L is integrally formed with the following structure so as to be attachable to and detachable from the housing: a male screw portion 41L in an upper half portion, and a screw combination body 5L is detachably screw-combined with the male screw portion 41L; a rotating portion 42L provided in the lower half portion; a diameter-expanding conical portion 43L provided between the male thread portion 41L and the rotating portion 42L; and a small diameter portion 44L provided at a lower end of the rotating portion 42L. The tapered surface of the enlarged diameter tapered portion 43L facing upward is engraved with serrations 45L. After the hinge shaft 4L is inserted into the shaft hole 32L of the vehicle-body-side base member 3L, the small diameter portion 44L is caulked so that the hinge shaft 4L cannot be pulled out from the shaft hole 32L.
The screw-thread combination 5L is integrally formed in the following configuration: a head 51L of the upper half; a cylindrical portion 53L having a female screw portion 52L formed on an inner peripheral surface thereof and capable of being screwed with the male screw portion 41L of the hinge shaft 4L; and a conical portion 54L which is located between the head portion 51L and the cylindrical portion 53L and has a diameter which gradually decreases as it goes downward.
The door-side base member 2L is manufactured by casting an aluminum alloy as a raw material in order to reduce the weight and improve the production efficiency, and is integrally formed with the following structure: a base portion 21L fixed to a mounting surface (vertical surface) of the door D by bolts (not shown); and a bearing portion 23L having a vertical shaft hole 22L into which the male screw portion 41L of the hinge shaft 4L is inserted. Mounting holes 24L, 24L penetrating in the front-rear direction, that is, in the direction perpendicular to the shaft hole 22L are formed in the base portion 21L of the door-side base member 2L, and bolts, not shown, for fixing the base portion 21L to the door D can be inserted into the mounting holes 24L, 24L from the front.
In order to prevent dissimilar metal contact corrosion occurring at the contact surface with the door D, the surface of the door-side base member 2L is subjected to the same surface treatment as that of the door-side base member 2U.
A stopper 25L is provided on the outer periphery of the bearing 23L of the door-side base member 2L, and the stopper 25L protrudes to the outside of the outer peripheral surface to regulate the fully open position of the door D. The stopper 25L abuts against the abutment surface 34L of the vehicle body side base member 3L, thereby restricting the fully open position of the door D in cooperation with the stopper 25U of the upper door hinge 1U.
The male screw portion 41L of the hinge shaft 4L is inserted into the shaft hole 22L of the door base member 2L from below, the cylindrical portion 53L of the screw-connected body 5L is inserted into the shaft hole 22L of the door base member 2L from above, and in this state, the female screw portion 52L of the screw-connected body 5L is screwed to the male screw portion 41L of the hinge shaft 4L. Thereby, the male screw portion 41L of the hinge shaft 4L is fixed to the shaft hole 22L of the door-side base member 2L so as not to rotate. Further, by detaching the screw-coupled body 5L from the male screw portion 41L of the hinge shaft 4L from above and displacing the door D upward, the door D can be detached from the vehicle body B in a state where the door-side base member 2L is fixed to the door D and the vehicle-body-side base member 3L is fixed to the vehicle body B.
A tapered portion 26L is provided at an upper inlet portion of the shaft hole 22L, the tapered portion 26L being in contact with the conical portion 54L of the screw coupling body 5L, and a tapered portion 27L is provided at a lower inlet portion of the shaft hole 22L, the tapered portion 27L being in contact with the serrations 45L of the diameter-expanding conical portion 43L provided on the hinge shaft 4L.
The screw-coupled body 5L is screw-coupled to the male screw portion 41L of the hinge shaft 4L and tightened with a tool, whereby the conical portion 54L of the screw-coupled body 5L is fitted into the conical portion 26L on the upper side of the shaft hole 22L of the door-side base member 2L from above by a wedge action. At the same time, the serrations 45L of the diameter-enlarged conical portion 43L of the hinge shaft 4L are fitted into the lower conical portion 27L of the shaft hole 22L from below by a wedging action, so that the upper half portion of the hinge shaft 4L is firmly fixed to the shaft hole 22L of the door-side base member 2L.
In the present embodiment, similarly to the upper door hinge 1U, the taper angle θ 1 of the taper portion 54L of the screw combination body 5L is set to 26 degrees, the taper angle θ 2 of the enlarged diameter taper portion 43L of the hinge shaft 4L is set to 28 degrees, and the taper angle θ 3 of the upper and lower taper portions 26L, 27L of the shaft hole 22L is set to 30 degrees larger than θ 1 and θ 2. Thus, the conical portion 54L of the screw-coupled body 5L can be reliably fitted into the upper conical portion 26L of the shaft hole 22L of the door-side base member 2L, and the serrations 45L of the diameter-enlarged conical portion 43L of the hinge shaft 4L can be reliably fitted into the lower conical portion 27L of the shaft hole 22L of the door-side base member 2L.
The vehicle-body-side base member 3L is manufactured by casting an aluminum alloy as a raw material in order to reduce the weight and improve the production efficiency, similarly to the door-side base member 2L, and integrally formed with the following structure: a base portion 31L fixed to a mounting surface (vertical surface) of the vehicle body B by bolts (not shown); and a bearing portion 33L, which is provided below the bearing portion 23L of the door-side base member 2L, and in which a vertical shaft hole 32L into which the rotating portion 42L of the hinge shaft 4L is inserted is bored.
The base portion 31L is formed with attachment holes 35L, 35L penetrating in the left-right direction, that is, in the direction orthogonal to the shaft hole 32L, and bolts, not shown, for fixing the base portion 31L to the vehicle body B can be inserted into the attachment holes 35L, 35L from the vehicle exterior side.
In order to allow the rotation portion 42L of the hinge shaft 4L to smoothly rotate in the shaft hole 32L, the upper flanged bush 6L is fitted into the shaft hole 32L of the vehicle-body-side base member 3L so as to be substantially non-rotatable from above, and the lower flanged bush 7L is fitted into the shaft hole 32L of the vehicle-body-side base member 3L so as to be substantially non-rotatable from below. The small diameter portion 44L of the hinge shaft 4L projecting downward from the lower bushing 7 is swaged so as not to be pulled out from the shaft hole 32L. Preferably, a washer 8L is present between the caulking portion and the flange portion 71L of the lower bushing 7L.
Thus, the rotation portion 42L of the hinge shaft 4L is assembled to the shaft hole 32L of the vehicle body side base member 3L through the bushes 6L, 7L so as to be relatively rotatable and not to be drawn out in the axial direction.
Next, the gist of the assembly and disassembly of the door D to and from the vehicle body B in the present embodiment will be described.
In a state where the door- side hinge members 2L, 2U and the vehicle- side hinge members 3L, 3U are separated from each other, the door- side hinge members 2U, 2L are fixed to the door D by bolts not shown in the drawings, and the vehicle- side hinge members 3U, 3L are fixed to the vehicle B by bolts not shown in the drawings.
In the vehicle body assembling step, when the door D is assembled to the vehicle body B, as can be understood from fig. 6, in the upper door hinge 1U, the male screw portion 41U assembled to the hinge shaft 4U of the door-side hinge member 2U is inserted from above into the shaft hole 32U of the vehicle-side hinge member 3U fixed to the vehicle body B side, and in the lower door hinge 1L, the shaft hole 22L of the door-side hinge member 2L is fitted from above to the male screw portion 41L assembled to the hinge shaft 4L of the vehicle-side hinge member 3L.
Next, in the upper door hinge 1U, the screw combination body 5U is screwed and tightened with the male screw portion 41U of the hinge shaft 4U from below. In the lower door hinge 1L, the screw combination body 5L is screwed and tightened with the male screw portion 41L of the hinge shaft 4L from above. Thereby, the door D is temporarily assembled to the vehicle body B.
Next, after finishing the painting and other processes in the vehicle body assembling process, the screw combination 5U is detached from the male screw 41U of the hinge shaft 4 from below in the upper door hinge 1U, and the screw combination 5L is detached from the male screw 41L of the hinge shaft 4L from above in the lower door hinge 1L. This allows the door D to be removed from the vehicle body B in a state where the door- side base members 2L and 2U are fixed to the door D and the vehicle-body- side base members 3L and 3U are fixed to the vehicle body B. The detached door D is transferred to an assembling process to mount various devices. The door D on which various devices are mounted is assembled to the vehicle body B as described above, and the screw combination 5L is formally fastened to the male screw portion 41L of the hinge shaft 4L, and the screw combination 5U is formally fastened to the male screw portion 41U of the hinge shaft 4U.
Next, a method for manufacturing the door-side hinge member 2U and the vehicle-body-side hinge member 3U of the upper door hinge 1U and the door-side hinge member 2L and the vehicle-body-side hinge member 3L of the lower door hinge 1L will be described. Note that, since the manufacturing methods of the hinge members 2U, 2L, 3U, and 3L are all the same, the door-side hinge member 2U of the upper door hinge 1U will be described as an example in the following description. The other hinge members 2L, 3L, and 3U can be easily understood from this description.
Fig. 10 is a schematic cross-sectional explanatory view of a casting mold 100 for manufacturing the door-side hinge member 2U.
The method for manufacturing the door-side hinge member 2U according to the present embodiment is based on an aluminum die casting method in which a plunger is used to pour a melt, which is a molten aluminum alloy as a raw material, at high pressure. The casting mold 100 includes a stationary mold 200, a movable mold 300, and slide cores 400 and 500, and a cavity 600 is defined in the casting mold 100 by the stationary mold 200 and the movable mold 300.
The melt 700 injected from the liquid supply port, not shown, is filled into the cavity 600 by sliding the plunger, not shown, in the sleeve 800.
The movable mold 300 is capable of moving forward and backward in a direction perpendicular to the fixed mold parting surface 201 of the fixed mold 200, that is, in the left-right direction in fig. 10, and the fixed mold parting surface 201 faces the movable mold parting surface 301. The movable mold 300 moves rightward in fig. 10, and the movable mold parting surface 301 and the fixed mold parting surface 201 abut against each other to be clamped, thereby forming a cavity 600. Further, the movable mold 300 retreats leftward in fig. 10, whereby the movable mold parting surface 301 and the fixed mold parting surface 201 are separated from each other to open the mold.
Preferably, the cavity 600 is divided so that a plurality of door-side hinge members 2U as molded articles can be obtained.
The slide core 400 is inserted into a guide hole 302 provided in the movable mold 300 so as to be movable up and down, and is configured to be able to advance and retreat in the cavity 600, and when the slide core 400 is lowered in fig. 10 and brought into the state shown in fig. 10 with respect to the cavity 600, it is positioned so as to be able to be clamped. The door-side hinge member 2U solidified in the cavity 600 can be taken out from the movable mold 300 by moving upward in fig. 10 with respect to the movable mold 300 and retreating from the cavity 600.
The slide core 500 is inserted into a guide hole 202 provided in the stationary mold 200 so as to be movable up and down, and is configured to be able to advance and retreat in the cavity 600, and when the slide core 500 is lowered in fig. 10 and brought into the state shown in fig. 10 with respect to the cavity 600, it is positioned so as to be able to be clamped. The door-side hinge member 2U solidified in the cavity 600 can be taken out from the fixed mold 200 by moving upward in fig. 10 with respect to the fixed mold 200 and retreating from the cavity 600.
The door-side hinge member 2U as a molded product taken out of the cavity 600 is finished by deburring a necessary portion for finishing.
The door-side hinge member 2U in the cavity 600 is manufactured so that the direction of the center axis X of the shaft hole 22U is the left-right direction in fig. 10, that is, parallel to the advancing and retreating direction of the movable mold 300. Thus, the shaft hole 22U of the door-side hinge member 2U can be formed without performing a drilling process in a separate step.
The mounting holes 24U, 24U of the door-side hinge member 2U are formed by the slide core 500 provided in the fixed mold 200 and the slide core 400 provided in the movable mold 300. Thus, since the mounting holes 24U, 24U are formed after the door-side hinge member 2U is manufactured by casting, it is not necessary to perform a hole forming process by a separate process.
In fig. 10, the left and right portions of the base portion 21U of the door-side hinge member 2U are formed with a casting draft of about 0.3 degrees or less with respect to the advancing and retreating direction of the movable mold 300, that is, the direction of the central axis X of the shaft hole 22U.
As described above, it can be understood that the lower hinge member 1L and the upper hinge member 1U are configured as in the present embodiment, and the respective hinge members 2L, 2U, 3L, and 3U are manufactured by casting using an aluminum alloy as a raw material, whereby the door D can be attached to and detached from the vehicle body B in a state where the door- side hinge members 2L and 2U are fixed to the door D and the vehicle- side hinge members 3L and 3U are fixed to the vehicle body B in the vehicle body assembly process, and the lower hinge member 1L and the upper hinge member 1U can be reduced in weight and improved in production efficiency.
Fig. 11 (a) and 11 (b) show modifications for manufacturing the hinge members 2L, 2U, 3L, and 3U of the present invention by casting.
For example, as can be understood from fig. 1 (b), in the case of a structure in which two mounting holes 35L, 35L provided in the base portion 31L are arranged so as to be spaced apart from each other in the front-rear direction, such as the vehicle-body-side hinge member 3L of the lower door hinge 1L, or a structure in which the number of the mounting holes 35L is 1, the mounting holes 35L can be molded by casting without using a slide core. This is achieved by the following structure: as shown in fig. 11 (a) and 11 (b), in order to prevent the mounting holes 35L and 35L from being undercut with respect to the fixed mold 200 and the movable mold 300 movable in the left-right direction in fig. 11 (b), a concave portion 38L is provided on the front surface of the base body portion 31L so as to be parallel to the direction of the central axis line X of the shaft hole 32L, the concave portion 38L is continuous with the left half of the mounting hole 35L and has a depth of 1/2 corresponding to the thickness of the base body portion 31L, and a concave portion 39L is provided on the rear surface of the base body portion 31L so as to be parallel to the central axis line X, the concave portion 39L is continuous with the right half of the mounting hole 35L and has a depth of 1/2 corresponding to the thickness of the base body portion 31L.
Therefore, in the present invention, when the hinge members 2L, 2U, 3L, and 3U are manufactured by an aluminum die-casting manufacturing method, the slide cores are not necessarily required by appropriately changing the positions of the mounting holes 24L, 24U, 35L, and 35U.
