  The first horizontal drive unit 53 for setting is a linear motor, a linear drive mechanism having a screw shaft, a motor that rotationally drives the screw shaft, and a nut portion screwed to the screw shaft, or a linear such as an air cylinder or a hydraulic cylinder. It is composed of an actuator, and the setting head mechanism 60 is moved between the position on the resin component spreading device 30 side and the position on the insert molding device 100 side via the setting second horizontal driving unit 54 and the setting lifting drive unit 55. It supports so as to be able to reciprocate between positions (see FIG. 3).

  The second horizontal drive unit 54 for setting is a linear motor, a linear drive mechanism having a screw shaft, a motor that rotationally drives the screw shaft, and a nut portion screwed to the screw shaft, or a linear drive mechanism such as an air cylinder or a hydraulic cylinder. A horizontal guide portion configured by an actuator and supported by the first horizontal driving portion 53 for setting so as to be movable and driven in a posture extending in a direction substantially orthogonal to the moving direction by the first horizontal driving portion 53. 54a and a horizontal movable portion 54b supported by the horizontal guide portion 54a so as to be movable and movable along the extending direction (see FIGS. 3 and 9).

  The set lifting drive unit 55 is a linear motor, a linear drive mechanism having a screw shaft and a motor that rotationally drives the screw shaft and a nut portion screwed to the screw shaft, or an air cylinder, a hydraulic cylinder, or the like. The lifting / lowering main body portion 55a, which is configured by a linear actuator or the like, is provided so as to hang down from the horizontal movable portion 54b, and the lifting / lowering movable portion provided so as to be movable forward and backward from the tip of the lifting / lowering main body portion 55a 55b.

  Further, the setting head mechanism 60 is supported in a three-dimensionally movable manner by the configuration including the first horizontal driving unit 53 for setting, the second horizontal driving unit 54 for setting, and the lifting driving unit 55 for setting. A supporting mechanism is configured.

  In addition, an inclination driving unit for setting 56 is provided at the lower end of the elevating movable unit 55b. The set inclination driving unit 56 is configured by a rotational driving mechanism such as a stepping motor that can be rotationally driven, and has a shaft portion 56a that can be rotationally driven at a predetermined angle. The axial part 56a should just be the structure which can be rotated in the forward / reverse direction at an angle (for example, about 45 degree | times) required in the setting operation | movement of the holder 15 mentioned later (refer FIGS. 11-13). Therefore, for example, the setting tilt driving unit may be configured to convert the linear motion of the linear actuator into a rotational motion and rotate the shaft portion in both forward and reverse directions.

  The rotation axis of the shaft portion 56 a of the setting tilt driving unit 56 is set in a direction along the horizontal direction, and the shaft portion 56 a extends to the side of the setting tilt driving unit 56. A setting head mechanism 60 is attached to the shaft portion 56a via a head mounting bracket 58.

  That is, the head mounting bracket 58 is formed in a shape obtained by bending a plate member into a substantially L shape. The shaft portion 56a is fixed to the outward surface of the flat plate portion 58a on one side of the head mounting bracket 58 in a substantially orthogonal posture with respect to the flat plate portion 58a. Further, the flat plate portion 58b on the other side of the head mounting bracket 58 is configured to extend outward from the set inclination driving portion 56 in a posture substantially orthogonal to the flat plate portion 58a. The head mounting bracket 58 can be driven to swing between a vertical posture in which the flat plate portion 58b is set to a substantially vertical posture and an inclined posture in which the flat plate portion 58b is inclined by driving the set tilt driving unit 56. . Here, the tilt posture is a posture tilted by a predetermined angle of less than 90 degrees (here, approximately 45 degrees) so as to move the flat plate portion 58b downward from the vertical posture. This tilt angle is set experimentally, empirically, etc., as described later, according to the shape of the holder 15, the shape of the core 104, and the like so that the holder 15 can be easily set on the core 104. The

  A set head mechanism 60 is supported on the inward surface of the flat plate portion 58b of the head mounting bracket 58.

  Here, of the operations of the resin component setting device 50, the operation of the setting operation mechanism unit 52 will be described.

  First, after the opening of the holder 15 is widened by the resin component spreading device 30, the resin component spreading device 30 is transported to a position on the resin component setting device 50 side by driving the spreading device transport driving unit 32. The setting head mechanism 60 is disposed at a position facing the upper side of the holder 15 set in the resin component spreading device 30 by driving the operating mechanism 52. Then, the set head mechanism 60 moves closer to the holder 15 by driving the set operation mechanism 52, so that the set head mechanism 60 clamps the holder 15 (see FIG. 9).

  Thereafter, the setting operation mechanism 52 arranges the setting head mechanism 60 at a position corresponding to one of the cores 104 of the insert molding device 100, and the setting operation is started.

  In the initial stage of setting the holder 15 with respect to the core 104, as shown in FIG. 11, the holder 15 held by the setting head mechanism 60 is inclined with respect to the protruding direction of the core 104, and the core 104 It is set as the state which contact | abuts to the front-end | tip part of (refer FIG. 11). In this state, one long side portion of the tip portion of the core 104 is disposed in the opening of the holder 15.

  Thereafter, the set head mechanism 60 is moved so as to approach the core 104 by driving the second horizontal driving unit 54 for setting, and the flat plate portion on the other side of the head mounting bracket 58 is driven by the tilt driving unit 56. It swings and drives so that 58b is in a substantially vertical posture (see FIG. 12). As a result, the axial direction of the holder 15 sandwiched between the set head mechanism 60 gradually approaches the protruding direction of the core 104, and a larger portion of the tip of the core 104 is within the opening of the holder 15. It comes to be arranged.

  In the state where the above operation is continuously performed and the holder 15 reaches the upper position of the core 104, the axial direction of the holder 15 sandwiched between the setting head mechanism 60 substantially coincides with the protruding direction of the core 104, The entire tip of the core 104 is disposed in the opening of the holder 15 (see FIG. 13).

  From this state, when the holder 15 is pushed toward the core 104 by driving the elevating drive unit 55 and a contact portion advancement drive unit 94 described later, the holder 15 is set so as to be covered with the core 104. Is inserted into the holder 15 as far as it will go.

  The set head mechanism 60 basically has a configuration for holding the holder 15 in the above operation. Here, when setting the holder 15 to the core 104, the setting head mechanism 60 prevents the core 104 from coming into contact with the holder 15 with a strong force. Is provided with the following configuration for suppressing the occurrence of shaving.

  14 is a side view showing the setting head mechanism 60, FIG. 15 is a bottom view showing the setting head mechanism 60, and FIG. 16 is a front view showing the setting head mechanism 60. FIG. 6 is a rear view showing the setting head mechanism 60.

  The setting head mechanism 60 includes a clamping part 62 having a pair of clamping pieces 74, a clamping part movable support part 80, a contact part 90, and a contact part advancing drive part 94. Then, by setting the holder 15 so as to cover the core 104 while holding the holder 15 so that the position and posture can be changed, the position and shape of the core 104 are imitated during the operation. The position and posture of the holder 15 are changed.

  That is, the sandwiching part 62 includes a sandwiching main body part 64, a pair of intermediate sandwiching arm parts 70, and a pair of sandwiching pieces 74.

  The sandwiching body portion 64 supports the pair of sandwiching pieces 74 through a pair of intermediate support arm portions 70 so as to be openable and closable, and is formed in a flat and substantially block shape here. As such a sandwiching main body 64, for example, a motor, a screw shaft in which screw grooves in different spiral directions are formed in one end portion and the other end portion, and one end portion and the other end of the screw shaft, respectively. A configuration having a pair of movable parts screwed into each of the side portions can be employed. Then, on one end side of the sandwiching main body portion 64, each of the pair of movable portions supports the pair of intermediate sandwiching arm portions 70 in a protruding posture so as to be able to approach and separate. In addition to the above, such a sandwiching main body may adopt a configuration in which a pair of movable members are driven to approach and separate from each other through a force transmission mechanism as appropriate using an air cylinder or a hydraulic cylinder as another drive source. it can.

  The pair of intermediate clamping arm portions 70 are each formed in a substantially L-shaped member. And while extending the linear part of one side toward the both sides outward of the clamping main-body part 64, the linear part of the other side is the opposite side to the clamping main-body part 64 from the outer side edge part of the said one-side linear part. One end portion of the intermediate clamping arm portion 70 is attached and fixed to the movable member of the clamping main body portion 64 in a posture that extends outward. Thereby, a space in which the holder 15 and the contact portion 90 can be disposed is formed between the straight portions on the other side of the pair of intermediate clamping arm portions 70.

  The pair of sandwiching pieces 74 are respectively attached to the distal end portions of the pair of intermediate sandwiching arm portions 70 via the sandwiching piece movable support portions 78. Each clamping piece 74 has a clamping piece main body 75 and a clamping elastic member 76. The sandwiching piece main body 75 is a member formed in a substantially rectangular parallelepiped shape, and a recess having a larger spread than the portion on the short side of the holder 15 is formed on the inward surface (the surface facing the holder 15). Has been. In addition, a thin plate-like sandwiching elastic member 76 is fixed to the inward surface of the sandwiching piece main body 75 by bonding or screwing. This sandwiching elastic member 76 is a member formed of an elastic material such as urethane. The pair of clamping pieces 74 can clamp the holder 15 via the elastic member 76.

  The sandwiching piece movable support portion 78 is configured to support the sandwiching piece 74 so as to be movable along a direction substantially orthogonal to the sandwiching direction by the pair of sandwiching pieces 74. This clamping direction is a direction substantially perpendicular to the moving surface of the holder 15 in the covering operation. Here, the sandwiching piece movable support portion 78 is a member constituted by, for example, a general linear guide or the like, and has a rail portion 78a that can be inserted into the guide groove 75a formed in the sandwiching piece main body portion 75. ing. The rail portion 78a is substantially orthogonal to the holding direction of the holder 15 by the pair of holding pieces 74 (that is, the opening / closing direction of the pair of holding pieces 74) and the insertion direction when the holder 15 is set on the core 104. It is fixed to the distal end portion of the intermediate clamping arm portion 70 in a posture along the direction. The rail 78a is inserted into the guide groove 75a of the sandwiching piece main body 75 so that the sandwiching piece 74 is movably supported in the above-described manner. In addition, the intermediate clamping arm portion 70 is provided with a pair of restricting pieces 71 for sandwiching the sandwiching piece 74 from both sides along the moving direction thereof. The sandwiching piece 74 is provided with the pair of restricting pieces 71. It is possible to move between. A biasing member 72 such as a coil spring that biases the sandwiching piece 74 toward one side in the moving direction is provided between one of the restriction pieces and the sandwiching piece 74. The clamping piece 74 is pressed against the other regulation piece 71 along the moving direction by the urging force.

  In the present embodiment, a clamping piece position detection sensor 73 that detects the movement position of the clamping piece 74 is provided. Here, the detection piece 75b is formed so as to extend from the portion on the one side of the regulation piece 71 side of the sandwiching piece main body part 75 to the intermediate sandwiching arm part 70 side. The sandwiching piece position detection sensor 73 is provided at a position facing the detection piece 75b with a gap through a sensor mounting bracket 73B fixed to the intermediate sandwiching arm 70. And the distance of the clamping piece position detection sensor 73 and the detection piece 75b is fluctuate | varied because the clamping piece 74 moves along the said direction. The clamping piece position detection sensor 73 detects the distance to the detection piece 75b and outputs the detection result to the control unit 21 or the like as a signal indicating the position of the clamping piece 74. The control unit 21 is configured to monitor an operation state in which the holder 15 is set on the core 104 based on the output.

  Then, the holding piece 15 is disposed between the pair of holding pieces 74 in a posture in which the longitudinal direction of the holder 15 and the approaching / separating movement direction of the pair of holding pieces 74 coincide with each other. The holder 15 is clamped by the pair of clamping pieces 74 by the pair of clamping pieces 74 being driven to approach. In this state, the sandwiching piece 74 and the holder 15 do not have a tight concave-convex fitting structure, and the holder 15 is sandwiched by the force with which the pair of sandwiching pieces 74 sandwich the holder 15. For this reason, the holder 15 can be changed in posture within a plane substantially orthogonal to the clamping direction by the pair of clamping pieces 74. In particular, in the present embodiment, the pair of sandwiching pieces 74 sandwich the holder 15 via the sandwiching elastic member 76. Therefore, the posture change of the holder 15 can be performed while sufficiently securing the sandwiching force of the holder 15. Ensuring enough.

  Note that the sandwiching elastic member 76 is not always necessary, and a member that does not substantially have elasticity may hold the holder 15 directly. Moreover, the surface which clamps the holder 15 among a pair of clamping pieces may be formed in the flat surface. That is, it is only necessary that the surface of the pair of holding pieces that holds the holder has no irregularities that restrict the posture of the holder 15 to a fixed state. Then, the pair of holding pieces 74 are driven to be separated by driving the holding piece main body 75 from the above state, whereby the holding of the holder 15 by the pair of holding pieces 74 is released.

  The clamping part movable support part 80 is configured to support the clamping part 62 so as to be movable in the clamping direction by a pair of clamping pieces 74. More specifically, the sandwiching portion movable support portion 80 is a member constituted by, for example, a linear guide or the like, and the rail portion 82 (here, a pair of rail portions 82) and the rail portion 82 can be disposed. And a movable portion 84 having guide groove portions 84a (here, a pair of guide grooves 84a). The rail portions 82 are inserted into the respective guide groove portions 84a, so that the movable portions are movable with respect to the rail portions 82. 84 is movable along the extending direction of the rail portion 82. The rail portion 82 is fixed to the inward surface of the flat plate portion 58b on the other side of the head mounting bracket 58, and the movable portion 84 is fixed to the holding piece main body portion 75. The sandwiching portion movable support portion 80 is disposed between the head mounting bracket 58 and the sandwiching portion 62 in a state where the moving direction of the sandwiching portion 62 is substantially coincident with the sandwiching direction.

  A pair of restricting pieces 83 for restricting the moving range of the movable portion 84 are formed on both sides of the flat plate portion 58b along the moving direction of the movable portion 84. A gap larger than the dimension of the movable part 84 (here, the dimension of the movable part 84 in the moving direction is smaller than the dimension of the sandwiching piece main body part 75 in the same direction) is provided between the pair of regulating pieces 83. (See FIG. 17). The clamping unit 62 is movable within a range in which the movable unit 84 can move between the pair of regulating pieces 83. Further, an urging member 85 such as a coil spring is disposed between the movable portion 54 and the pair of restricting pieces 83. The movable member 84 and the sandwiching portion 62 are urged by the urging member 85 so as to be positioned approximately at the center between the pair of restricting pieces 83.

  The contact portion 90 is a member configured to be able to contact the holder 15 sandwiched by the pair of sandwiching pieces 74 from the base end side of the pair of sandwiching pieces 74, and the contact portion advancing drive unit 94 is The abutting portion 90 is configured to advance to the distal end side of the pair of sandwiching pieces 74.

  More specifically, the abutting portion advancing drive portion 94 is a member constituted by various linear drive mechanisms such as an air cylinder and a hydraulic cylinder, and has a rod portion 94a that can be driven forward and backward. The abutment portion advancing drive portion 94 is in a posture in which the rod portion 94a is disposed so as to be able to advance and retreat toward the distal end side of the pair of sandwiching pieces 74, and the sandwiching portion movable support portion of the sandwiching piece main body portion 75. It is fixedly attached to the opposite surface of 80.

  The contact portion 90 includes a connecting portion 90a connected to the tip portion of the rod portion 94a, an intermediate extending piece 90b extending from the connecting portion 90a toward the tip side of the pair of holding pieces 74, and the intermediate extending portion. A contact piece 90c that bends and extends from the tip of the piece 90b toward the pair of intermediate holding arm portions 70 and the pair of holding pieces 74 is provided. In the state in which the distal end portion of the rod portion 94a is retracted, the contact piece 90c is retracted to the proximal end side of the pair of sandwiching pieces 74 and is positioned between the pair of intermediate sandwiching arm portions 70. Further, in a state where the distal end portion of the rod portion 94a has advanced, the contact piece advances between the pair of sandwiching pieces 74 and the holder 15 sandwiched by the pair of sandwiching pieces 74 is pushed out to the distal end side. ing.

  The operation of the set head mechanism 60 during the above-described covering operation will be described.

  First, as shown in FIG. 11, an initial setting operation of the holder 15 with respect to the core 104 is assumed. In this state, the holder 15 is clamped by the pair of clamping pieces 74 and the lid portion 15 a of the holder 15 is in contact with the contact portion 90. In this case, as shown in FIG. 18, it is assumed that the holding position of the holder 15 by the setting head mechanism 60 is displaced with respect to the core 104 in the clamping direction (in FIG. 18, with respect to the core 104). The holder 15 is exaggeratedly drawn on the right side). In this case, if the holding position of the holder 15 is constant in the clamping direction, one side of the core 104 and the inner surface of the holder 15 come into contact with each other with a strong force, and the holder 15 is damaged or scraped. There is a fear. However, as described above, the clamping part 62 that clamps the holder 15 is supported by the clamping part movable support part 80 so as to be movable along the clamping direction. For this reason, the holder 15 and the holding part 62 are arranged in the holding direction so that the resistance action when the holder 15 is set is reduced, that is, the center of the core 104 and the center of the holder 15 substantially coincide with each other in the holding direction. It moves along (it moves to the left in FIG. 18). Thereby, it is suppressed that the one side part of the core 104 and the inner surface of the holder 15 contact with strong force.

  Next, as shown in FIGS. 11 to 13, it is assumed that the holder 15 is moved from an oblique posture to a substantially vertical posture. In this case, assuming that the holding position of the holder 15 by the setting head mechanism 60 is constant on a surface substantially orthogonal to the clamping direction, the core 104 moves to the inner surface of the holder 15 as the setting head mechanism 60 operates. On the other hand, the holder 15 may come into contact with a strong force, and the holder 15 may be damaged or scraped. However, as described above, the holder 15 is supported between the pair of clamping pieces 74 so as to be movable in a plane substantially perpendicular to the clamping direction. For this reason, when the core 104 tries to contact the inner surface of the holder 15 with a strong force, the holder 15 changes its posture between the pair of holding pieces 74 so as to relieve the force (see the two-dot chain line in FIG. 19). ). In other words, when the holder 15 is tilted from an oblique position to a substantially vertical position, the core 104 is moved between the pair of holding pieces 74 so as to relieve the core 104 from contacting the inner surface of the holder 15 with a strong force. The position of the holder 15 is changed according to the shape of the core 104. Thereby, it is suppressed that the core 104 and the inner surface of the holder 15 contact with a strong force.

  In the present embodiment, since a recess having a larger extent than the portion on the short side of the holder 15 is formed inward of the pair of sandwiching pieces 74, the posture of the holder 15 between the pair of sandwiching pieces 74. The change range is regulated within a range in which the posture can be changed within the recess. As a result, the holder 15 is changed to the substantially vertical posture while changing the posture as described above.

  The pair of sandwiching pieces 74 are supported by the sandwiching piece movable support portion 78 so as to be movable along a direction substantially orthogonal to the sandwiching direction by the pair of sandwiching pieces 74. For this reason, the holder 15 moves along the moving direction so as to relieve the core 104 from coming into contact with the inner surface of the holder 15 with a strong force even in the direction during the setting operation. Can do. Also from this point, it is suppressed that the core 104 and the inner surface of the holder 15 contact with a strong force.

  Note that the position of the pair of sandwiching pieces 74 is detected by the sandwiching piece position detection sensor 73 in the moving support direction by the sandwiching piece movable support portion 78. In the control unit 21, the operation state of the set work can be monitored based on the detection output from the clamping piece position detection sensor 73. For example, when it is determined that the displacement amount of the pair of sandwiching pieces 74 is larger than other average values in the setting operation of the predetermined holder 15, it is determined that there is a possibility that some trouble has occurred. be able to.

  20 and 21 are explanatory views showing an operation in which the setting head mechanism 60 sets the holder 15 to the core 104 after the holder 15 is set to a substantially vertical posture (see FIG. 13).

  That is, after the setting head mechanism 60 changes the posture so that the holder 15 is in a substantially vertical posture, as shown in FIG. By driving 55, the setting head mechanism 60 moves toward the core 104. As a result, the holder 15 is partially covered with the core 104.

  Thereafter, as shown in FIG. 21, the contact portion 90 is advanced toward the distal end side of the pair of sandwiching pieces 74 by driving of the contact portion advancement drive portion 94. Then, the holder 15 is pushed out from between the pair of sandwiching pieces 74 to the front end side by the contact portion 90, and the holder 15 is further covered with the core 104, and the setting operation of the holder 15 with respect to the core 104 is completed. .

  Note that this operation may be performed by the operation of only the setting head mechanism unit 60 or by the operation of only the contact portion advancement drive unit 94. In the former case, the abutting portion 90 is not necessarily provided so as to be able to advance and retreat by the abutting portion advancing drive portion 94, and is provided at a fixed position where it can abut on the holder 15 sandwiched by the pair of sandwiching pieces 74. It may be done.

<Insert molding equipment>
FIG. 22 is a schematic plan view showing the insert molding apparatus 100, and FIG. 23 is a schematic side view showing the insert molding apparatus 100.

  The insert molding apparatus 100 includes a first mold (also referred to as a lower mold) 102 and a second mold (also referred to as an upper mold) 110. The first mold 102 and the second mold 110 are The waterproof part 14 is molded as a device using the holder 15 as an insert.

  Here, two first molds 102 are provided. More specifically, the first mold 102 is provided at two locations on the substantially disc-shaped mold moving member 120 supported rotatably via the shaft 122 with the center thereof interposed therebetween. One of the two first molds 102 is disposed at a set position (the left position in FIGS. 22 and 23) where the holder 15 can be set by the resin component setting device 50, and the other is the first. 2 is disposed at a molding position below the mold 110 (the right position in FIGS. 22 and 23). The shaft 122 can be rotated by a rotation drive mechanism 124 including a motor and the like. Then, by rotating the mold moving member 120 by the rotation drive of the rotation drive mechanism 124, the first mold 102 at the set position is moved to the molding position, and the first mold 102 at the molding position is set. The movement to the position is performed continuously.

  However, the number of the first mold 102 may be one or three or more, and the configuration for moving the first mold 102 is not limited to the above example, and is a configuration for reciprocating linearly. Also good. Further, the holder 15 may be set and molded at the same position with respect to the first mold 102.

  The first mold 102 includes a substantially block-shaped mold main body 103 and a core 104 protruding from the mold main body 103. The core 104 has a shape corresponding to the shape of the inner peripheral surface of the holder 15 and is configured to be set so as to cover the holder 15. The core 104 also has a mold surface that forms a circumferential inner surface shape when the waterproof component 14 is molded. Here, four cores 104 are formed on the upper surface of the first mold 102. The number of the cores 104 is not necessarily four, and may be 1 to 3, or 5 or more as necessary.

  The second mold 110 is provided at a position away from the set position laterally, here, at a position facing the set position with the rotation axis of the mold moving member 120 interposed therebetween. The second mold 110 is provided to be capable of being opened and closed with respect to the first mold 102 at the molding position by a mold opening / closing mechanism 126 provided on one side of the mold moving member 120. When the second mold 110 is in the upper mold open state, the first mold 102 is movable, and when the second mold 110 is in the lower position, the second mold 110 and the molding position are set. The first mold 102 in the state is clamped.

  The second mold 110 has a configuration in which a mold recess 112 is formed in a substantially block-shaped member. The mold recess 112 is formed in a concave shape in which the core 104 and the holder 15 set in the core can be disposed. Then, in a state where the first mold 102 and the second mold 110 are closed, the holder 15 is interposed between the peripheral portion of the core 104 of the first mold 102 and the mold recess 112 of the second mold 110. A mold space is formed in order to form the seal portion 16 of the waterproof part 14.

  The second mold 110 has an injection port 114 for injecting molten rubber or the like, and is configured so that the molten rubber is injected into the mold space through the injection port. Yes.

  Moreover, the opening part of the metal mold | die recessed part 112 is formed in the guide surface 112g expanded sequentially toward outward (downward). As a result, when the first mold 102 and the second mold are closed, even if the opening of the holder 15 set on the core 104 is in an expanded state, the opening of the holder 15 is not in the guide. It is configured to be narrowed by sliding contact with the surface 112g.

  That is, as described above, the opening of the holder 15 is widened by the resin component spreading device 30 so that the holder 15 can be easily set on the core 104. For this reason, even when the holder 15 is set on the core 104 as described above, the opening of the holder 15 is expanded so as to float from the side surface of the core 104 as shown in FIG. . In FIG. 24, the state in which the opening of the holder 15 floats from the side surface of the core 104 is exaggerated.

  In the above state, as shown in FIG. 25, when the second mold 110 is closed with respect to the first mold 102, the widened opening of the holder 15 is in sliding contact with the guide surface 112 g of the mold recess 112. It is narrowed by. For this reason, in the manufactured waterproof component 14, each wall part 15b, 15c becomes a substantially perpendicular attitude | position with respect to the cover part 15a, and the thing close | similar to the initial design preferable as a product is obtained. Moreover, in order to inject molten rubber or the like with the first mold 102 and the second mold 110 closed, the holder 15 is heated in the above state. For this reason, the residual stress of the holder 15 is relieved, and it can be expected that a shape closer to the initial design can be obtained.

<Description of operation>
The overall operation of the waterproof connector part manufacturing apparatus 20 will be described by paying attention to the resin part spreading apparatus 30, the resin part setting apparatus 50, and the insert molding apparatus 100.

  First, the holder 15 is conveyed to the resin component spreading device 30 via the holder supply unit 22 and the holder supply conveyance unit 24. After expanding the opening of the holder 15, the resin component spreading device 30 moves from the position on the holder supply / conveyance unit 24 side to the position on the resin component setting device 50 side.

  Subsequently, the resin component setting device 50 sandwiches the holder 15 conveyed by the resin component spreading device 30 and sets the holder 15 on the core 104 of the first mold 102 of the insert molding device 100.

  At this time, since the opening of the holder 15 is widened, the holder 15 can be set on the core 104 relatively easily.

  Further, the setting head mechanism 60 supports the holder 15 so as to be movable on a surface substantially orthogonal to the clamping direction by a pair of clamping pieces 74, and also supports the holder 15 along the clamping direction by a clamping unit movable support unit 80. Further, the holder 15 is supported by the pair of sandwiching piece movable support portions 78 so as to be movable in a direction substantially perpendicular to the sandwiching direction. The core 104 is set while changing its position and posture so as to follow.

  By repeating the above, the holder 15 is set in each of a plurality (four in this case) of the cores 104 of the first mold 102 of the insert molding apparatus 100. Thereafter, the first mold 102 in the set position moves to the molding position, and the second mold 110 descends toward the first mold 102 in the molding position, so that the first mold 102 and the second mold 102 are moved downward. The mold 110 is clamped. At this time, the widened opening of the holder 15 is narrowed by sliding contact with the guide surface 112 g of the mold recess 112, and is deformed in close contact with the side surface of the core 104. Thereby, each wall part 15b, 15c of the holder 15 becomes a substantially perpendicular | vertical attitude | position with respect to the cover part 15a, and the thing of the shape close | similar to an initial design is obtained. Then, the waterproof part 14 is manufactured by injecting molten rubber or the like to form the seal portion 16. Thereafter, the first mold 102 at the molding position moves to the set position, and the waterproof component take-out device 150 removes the waterproof parts 14 from the respective cores 104 of the first mold 102 at the set position collectively or sequentially. By gripping and taking out, the waterproof part 14 which is a finished product is obtained.

  According to the waterproof connector part manufacturing apparatus 20 configured as described above, when the holder 15 is put on the core 104 by the setting operation mechanism 52, the holder 15 follows the position and shape of the core 104. The holder 15 changes its posture between the pair of sandwiching pieces 74 and the sandwiching portion 62 moves along the sandwiching direction so as to be disposed on the distal end side. Thereby, it is suppressed that the core 104 contacts the holder 15 with a strong force, and when the holder 15 is set on the core 104, the damage and scraping of the holder 15 can be suppressed. Thereby, the waterproof component 14 of the stable quality can be manufactured.

  Further, the holder 15 is advanced by the drive of the contact part advance drive unit 94 in a state where the holder 15 is disposed on the distal end side of the core 104, so that the holder 15 is further covered with the core 104. The holder 15 can be covered more deeply with respect to the core 104. In particular, since the holder 15 is pushed in with the set head mechanism 60 disposed at a fixed position, the positioning accuracy of the holder 15 in the final set state is improved.

  Further, since the pair of sandwiching pieces 74 sandwich the holder 15 via the sandwiching elastic member 76, the holder 15 supports the holder 15 so that the holder 15 can be changed in posture while suppressing damage or damage to the holder 15. can do.

  Since the opening of the holder 15 is widened by the resin component spreading device 30 before the holder 15 is set on the core 104, the holder 15 can be smoothly set on the core 104. Scratching and scraping can be more reliably suppressed.

  In addition, when the opening of the holder 15 is expanded from the inside, the cover 15 a of the holder 15 is pressed with the resin component holding portion 42, so that the escape of the holder 15 can be suppressed.

  Further, when the first mold 102 and the second mold 110 are clamped, the widened opening of the holder 15 is narrowed by sliding contact with the guide surface 112g of the mold recess 112, and the core 104 Since it is deformed in close contact with the side surface, a shape close to the original design is obtained.
