Description

【Technical Field】 【0001】 The present invention relates to a method for manufacturing a resin molded product, a resin molded product manufactured by the manufacturing method, and an insert molding die used in the manufacturing method. 【Background Art】 【0002】 Conventionally, a resin molded product in which an insert member and a resin molded body are integrated has been manufactured by setting an insert member in a mold and filling molten resin around the insert member. For example, Patent Document 1 (Japanese Patent No. 5546696) discloses a technique for exposing a contact pin electrically connected to an electrode pattern of a base film inserted into an injection molded product from a molding resin by insert molding. 【Prior Art Documents】 【Patent Documents】 【0003】 【Patent Document 1】 Japanese Patent No. 5546696 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0004】 Although a rod-shaped insert member such as the contact pin described in Patent Document 1 is exposed from the resin molded body, it is difficult to expose a member having a complicated shape such as a connector to the outside of the resin molded body by insert molding. Therefore, conventionally, after insert molding, a through hole penetrating to an insert member for making an electrical connection is provided in the resin molded body, and after making an electrical connection of the connector using the through hole, a manufacturing method of filling the through hole with a sealing material is often used. 【0005】 However, if you use a through-hole to make an electrical connection, for example, with a connector, and then fill the through-hole with a sealing material, it is not only time-consuming, but if the sealing with the sealing material is insufficient, moisture or other substances may enter the connection area, causing malfunctions or other problems. The object of the present invention is to provide an insert molding method in which a part of an insert member is exposed to the outside of a resin molded body, in which the embedded portion following the exposed portion is sufficiently supported by the resin of the resin molded body itself and the embedded portion is sufficiently sealed. [Means for solving the problem] 【0006】 Several embodiments for solving the problem are described below. These embodiments can be combined as needed. The present invention relates to a method for manufacturing a resin molded product in which a resin molded body and an insert member are integrated by insert molding, and the insert member has a main body portion inserted into the resin molded body, an embedded portion protruding from the main body portion and embedded in the resin molded body, and an exposed portion extending from the embedded portion and exposed to the outside of the resin molded body. The method for manufacturing a resin molded product comprises a first step of setting the insert member between a first mold and a second mold, a second step of clamping the first mold and the second mold to form a molding space containing the insert member, a third step of pouring molten resin into the molding space and solidifying the molten resin to mold a resin molded body with the insert member inserted, and a fourth step of opening the first mold and the second mold to remove the resin molded body. The wall surface of the molding space includes the first surface of the first mold and the second surface of the second mold. In the second step, the sliding pins are slid in sync with the clamping operation of the first and second molds, changing the position of the sliding pins so that the embedded portion of the insert member is exposed to the molding space while the exposed portion is enclosed by the sliding pins, and the sliding pins form a third surface on the wall of the molding space at the boundary between the embedded portion and the exposed portion. In the third step, the embedded portion is positioned in the molten resin and the molten resin is poured in and solidified until the molten resin comes into contact with the third surface. In the fourth step, the sliding pins are slid to change the position of the sliding pins so that the exposed portion is released from being enclosed by the sliding pins. In this method of manufacturing a resin molded product, the sliding pins change to enclose the exposed portion, so even if the shape of the exposed portion is complex, it is possible to easily manufacture a resin molded product having an insert member in which the exposed portion is exposed to the outside of the resin molded body and the embedded portion is embedded inside the resin molded body. In the resin molded product manufactured in this way, the embedded portion is firmly supported by the resin molded body, and the area around the boundary between the embedded portion and the main body is sealed by the resin molded body. 【0007】 The above-described method for manufacturing a resin molded product can be configured such that, in the second step, the exposed portion is housed in the housing of the sliding pin in an open state in synchronization with the mold clamping operation, and the housing is deformed into a closed state to enclose the exposed portion and form a third surface; in the third step, molten resin is not allowed to flow into the housing; and in the fourth step, the housing is deformed from a closed state to an open state to remove the exposed portion from the housing. In this method for manufacturing a resin molded product, the sliding pin can be changed by utilizing the mold clamping operation by deforming the housing from an open state to a closed state in synchronization with the mold clamping operation, thereby simplifying the manufacturing process and manufacturing equipment. 【0008】 In the above-described method for manufacturing a resin molded product, the housing portion for the sliding pin can be configured such that it includes a plurality of divided pieces, which slide and combine to form a closed state when the exposed portion is housed inside the housing portion in the second step, and separate to form an open state when the exposed portion is removed from the housing portion in the fourth step. In this method for manufacturing a resin molded product, since the housing portion consists of a plurality of divided pieces, it becomes easier to form the housing portion to match the shape of the exposed portion. 【0009】 The above-described method for manufacturing a resin molded product can be configured such that the multiple segmented pieces slide away from the resin molded body when separated. In this configuration, the influence of the sliding pins on the resin molded product during sliding can be reduced. The above-described method for manufacturing a resin molded product involves an exposed portion having an annularly protruding dam portion on its outer surface to block molten resin, and a housing portion having an annular groove portion that allows the exposed portion to move in a direction intersecting the sliding direction and to contact the dam portion in an annular manner. With this configuration, the tolerance for dimensional errors of the insert member can be increased. 【0010】 The present invention relates to a resin molded product comprising a resin molded body made of a thermoplastic resin and an insert member inserted into the resin molded body by insert molding. The insert member has a main body portion inserted into the resin molded body, an embedded portion protruding from the main body portion and embedded in the resin molded body, and an exposed portion extending from the embedded portion and exposed to the outside of the resin molded body. The exposed portion includes an outer peripheral surface exposed from the resin molded body and a protrusion protruding from the outer peripheral surface. The aforementioned resin molded product allows for complex shapes in the exposed portion of the insert member due to the protrusions that extend from the outer surface, enabling, for example, the creation of a connector with a complex shape. The resin molded product described above can be configured to have a dam portion on its outer surface that protrudes in an annular shape and is in contact with the resin molded body. The resin molded product described above includes a film substrate having an electrical circuit in its main body. The exposed portion includes a connector or terminal that is electrically connected to the electrical circuit. In a resin molded product configured in this way, the connector or terminal is firmly supported by the resin molded body, and the electrical connection between the electrical circuit and the connector or terminal can be protected by the resin molded body. 【0011】 The insert molding die according to the present invention is an insert molding die for manufacturing a resin molded product in which a resin molded body and an insert member are integrated by insert molding, and the insert member has a main body portion inserted into the resin molded body, an embedded portion protruding from the main body portion and embedded in the resin molded body, and an exposed portion extending from the embedded portion and exposed to the outside of the resin molded body. The die comprises a first mold having a first surface for forming the wall surface of the molding space for molding the resin molded body, a second mold having a second surface, and a sliding pin having a third surface for forming the wall surface of the molding space. The sliding pin has a housing portion for housing the exposed portion. The housing portion changes from an open state to a closed state to house the exposed portion when the mold is clamped, and changes from a closed state to an open state when the mold is opened so that the exposed portion can be removed. The insert molding die configured in this way can be applied even if the shape of the exposed portion that is exposed to the outside of the resin molded body is complex. 【Advantages of the Invention】 【0012】 In the method for manufacturing a resin molded product, the resin molded product, and the insert molding die according to the present invention, in a resin molded product including an insert member having an exposed portion exposed to the outside of the resin molded body, a buried portion following the exposed portion can be sufficiently supported by the resin of the resin molded body itself and the buried portion can be sufficiently sealed. 【Brief Description of the Drawings】 【0013】 [Figure 1] It is a perspective view of a resin molded product according to an embodiment.

[Modes for carrying out the invention] 【0014】 <First Embodiment> (1) Composition of resin molded product Figures 1 and 2 show an example of a resin molded product 1 manufactured by a resin molded product manufacturing method according to the first embodiment of the present invention. Figure 2 shows a cross-section cut along line II in Figure 1. The resin molded product 1 comprises a resin molded body 10 and an insert member 20. The resin molded product 1 is formed by integrating the resin molded body 10 and the insert member 20 by insert molding. The insert member 20 has a main body portion 30, an embedded portion 40, and an exposed portion 50. The main body portion 30 is inserted into the resin molded body 10. The main body portion 30 shown in Figures 1 and 2 is a thin member that has a rectangular shape when viewed from above. The main body portion 30 is part of the insert member 20. The main body portion 30 is, for example, a film substrate having an electrical circuit (not shown). However, the main body portion 30 is not limited to a film substrate and may be made of other materials. Also, the shape of the main body portion 30 is not limited to a film shape and may be other shapes such as a cube or a sphere. Furthermore, the main body portion 30 is partially embedded in the resin molded body 10 and partially exposed from the first main surface 11 of the resin molded body 10. However, the location where the main body portion 30 is placed is not limited to the first main surface 11. The main body portion 30 can also be placed so as to be embedded inside the resin molded body 10. The main body 30 can also be arranged such that a portion is embedded in the resin molded body 10, a portion is exposed from the first main surface 11, and a portion is exposed from the second main surface 12. The main body 30 can also be arranged such that a portion is embedded in the resin molded body 10, and a portion is exposed from the side surface 13 of the resin molded body 10. 【0015】 The embedded portion 40 is the part that protrudes from the main body portion 30 and is embedded in the resin molded body 10. The embedded portion 40 is part of the insert member 20. The exposed portion 50 is the part that extends from the embedded portion 40 and is exposed to the outside of the resin molded body 10. The exposed portion 50 is also part of the insert member 20. The exposed portion 50 includes an outer peripheral surface 51 exposed from the resin molded body 10 and two protrusions 52 protruding from the outer peripheral surface 51. The outer peripheral surface 51 is the surface of the cylindrical exposed portion 50 with an oval cross-section. The two protrusions 52 are positioned further from the central axis than the distance from the central axis of the cylindrical exposed portion 50 to the outer peripheral surface 51. Therefore, even if a hole the same size as the outer peripheral surface 51 of the exposed portion 50 is formed in the second mold 120 (see Figure 4), the protrusions 52 will get caught and cannot be accommodated in the hole. Here, the buried portion 40 and the exposed portion 50 constitute a single component. The component consisting of the buried portion 40 and the exposed portion 50 is, for example, a connector. The connector, including the buried portion 40 and the exposed portion 50, is electrically connected to the electrical circuit of the main body portion 30, which is, for example, a film substrate. However, the component including the buried portion 40 and the exposed portion 50 is not limited to a connector, but may be other components. Here, the component including the buried portion 40 and the exposed portion 50 is cylindrical, but the shape of the component including the buried portion 40 and the exposed portion 50 is not limited to cylindrical. The shape of the component including the buried portion 40 and the exposed portion 50 may be other shapes, such as columnar, weight-shaped, or plate-shaped. Furthermore, although this description explains the case where the main body 30, the buried portion 40, and the exposed portion 50 are separate components, they may also be a single integrated component. Here, this description explains the case where there is one main body 30, one buried portion 40, and one exposed portion 50. However, there may be multiple main body 30s, multiple buried portions 40s, and multiple exposed portions 50s. 【0016】 (2) Overview of the manufacturing method for resin molded products Figure 3 shows a flow chart of the manufacturing method for the resin molded product 1. Figures 4 to 7 show the mold 100 and insert member 20 in the manufacturing process of the resin molded product 1. A cross-section of the resin molded product 1, which comprises the insert member 20 and the resin molded body 10, is shown in Figure 2, which has already been described. The main body portion 30 of the insert member 20, shown in Figure 4, is set on the first surface 118 of the first mold 110. One main surface of the main body portion 30 has, for example, copper wiring (not shown) for forming an electrical circuit and electrode terminals (not shown) electrically connected to the copper wiring. The mold 100 comprises a first mold 110 having a first surface 118 for forming the wall surface of the molding space for molding the resin molded body 10 and a second mold 120 having a second surface 128 (see Figure 5). The mold 100 also comprises a sliding pin 130 and an ejector pin 140 (see Figure 4). Furthermore, the mold 100 comprises an ejector plate 150 and a cylinder 160. 【0017】 In the first step S1, the insert member 20 is set between the first mold 110 and the second mold 120. The insert member 20 is positioned such that one main surface of the main body 30 faces the direction in which the molding space SP (see Figure 6) is formed. The embedded portion 40 and the exposed portion 50 (cylindrical portion) of the insert member 20 protrude from the main body 30 in the direction in which the sliding pin 130 slides. 【0018】 In the second step S2, the first mold 110 and the second mold 120 are clamped together to form a molding space SP (see Figure 6) for housing the insert member 20. Figures 4 and 5 show the state in which the first mold 110 and the second mold 120 are being clamped together. Figure 6 shows the state after the clamping of the first mold 110 and the second mold 120 is complete. In Figure 4, cross-sections of the first mold 110 and the second mold 120 are shown, with the sides of the sliding pin 130 and ejector pin 140 visible. In Figure 5, the main body 30 is omitted from the description in order to make the embedded part 40 and the exposed part 50 easier to see. For example, the embedded part 40 has electrode terminals 41 for connecting to the electrode terminals of the main body 30. In the second step S2, the sliding pin 130 is slid in synchronization with the clamping operation of the first mold 110 and the second mold 120. The mold 100 deforms the sliding pin 130 so that the embedded portion 40 of the insert member 20 is exposed to the molding space SP while the exposed portion 50 is enclosed by the sliding pin 130. When the clamping is completed (see Figure 6), the sliding pin 130 forms a third surface 138, which is part of the wall surface of the molding space SP, at the boundary between the embedded portion 40 and the exposed portion 50. Here, when the clamping is completed, the upper surfaces of the divided pieces 131 and 132 of the sliding pin 130 become flush with the second surface 128 of the second mold 120, becoming the third surface 138 of the molding space SP. The molding space SP shown in Figure 6 is a closed space with the first surface 118, the second surface 128 and the third surface 138 as its walls. The housing portion 133 for the sliding pin 130 includes a plurality of divided pieces 131, 132. In other words, in the configuration shown in Figures 4 and 5, the two divided pieces 131, 132 constitute the housing portion 133. Referring back to the housing portion 133, in the second step S2, synchronized with the clamping operation, the exposed portion 50 is housed inside the housing portion 133 of the sliding pin 130 in its open state, and the housing portion 133 is deformed into a closed state. As a result, the housing portion 133 encloses the exposed portion 50 and forms a third surface 138. The two divided pieces 131 and 132 move and combine in the second step S2 when the exposed portion 50 is housed inside the housing portion 133, thereby transforming into a closed state. 【0019】 In the third step S3, molten resin is poured into the molding space SP and solidified to form a resin molded body 10 (see Figure 1) into which the insert member 20 is inserted. In the third step S3, molten resin is injected into the molding space SP and cooled to solidify the molten resin. In the third step S3, the embedded portion 40 is positioned in the molten resin and the molten resin is poured in and solidified until it comes into contact with the third surface 138. 【0020】 In the fourth step S4, the molds of the first mold 110 and the second mold 120 are opened to remove the resin molded body 10 in which the insert member 20 is inserted. The removed resin molded body 10 has, for example, an exposed portion 50 as shown in Figure 1, exposed from the resin molded body 10. On the other hand, the embedded portion 40 is embedded in the resin molded body 10. In the fourth step S4, the two divided pieces 131 and 132 are deformed into an open state by separating when the exposed portion 50 is removed from the housing portion 133. In conventional insert molding, a series of steps from the first step S1 to the fourth step S4 are repeated to produce multiple resin molded products 1. 【0021】 (3) Materials used in the manufacture of resin molded products (3-1) Insert member As the insert member 20, the main body 30 is, for example, a film-like or plate-like printed circuit board. For example, if the main body 30 is a film-like printed circuit board, the film substrate, which is the main material of the printed circuit board, is insulating. For example, a resin film or an elastomer film can be used as the insulating film substrate. For example, the resin film material can be a thermosetting resin or a thermoplastic resin. For example, the resin film material can be polyimide, polyethylene terephthalate, polycarbonate, or cycloolefin. In addition to a film substrate, a three-dimensional substrate having a three-dimensional shape can also be used for the main body 30. For example, a MID (Molded Interconnect Device) can be used for the main body 30, and wiring may be formed on the surface of a three-dimensional member by LDS (Laser Direct Structuring). 【0022】 (3-2) Materials for resin molded products Examples of thermoplastic resins used as materials for molten resins include polyester resin, polyethylene terephthalate (PET) resin, acrylic resin, polycarbonate resin, polybutylene terephthalate (PBT) resin, triacetylcellulose resin, polyimide resin, polyethylene naphthalate (PEN) resin, liquid crystal polymer (LCP) resin, cycloolefin polymer (COP), styrene resin, and ABS resin. 【0023】 (4) Mold description (4-1) Type 1 and Type 2 In the first embodiment, the first mold 110 is the cavity and the second mold 120 is the core. The first mold 110 and the second mold 120 are made of metal, and the metal material can be, for example, iron, steel, or stainless steel. The first surface 118 of the first mold 110 and the second surface 128 of the second mold are combined with the third surface 138 of the sliding pin 130 to form a molding space SP into which molten resin is poured. 【0024】 (4-2) Sliding pin The sliding pin 130 includes divided pieces 131, 132 and a sliding portion 135. The sliding pin 130 is made of metal, for example, iron, steel, or stainless steel. The sliding pin 130 is shown in Figures 7, 8, 9, and 10. The two divided pieces 131 and 132 constitute the housing portion 133. The sliding portion 135 is fixed to the ejector plate 150. The sliding portion 135 slides as the ejector plate 150 moves. Here, the sliding portion 135 slides in the same direction as the movement of the first type 110. The sliding portion 135 has a T-groove 171 for slidably supporting the divided pieces 131 and 132. Each divided piece 131 and 132 has a slider 172 with a T-shaped cross-section that fits into the T-groove 171. The divided pieces 131 and 132 move in a direction perpendicular to the sliding direction of the sliding portion 135 as the slider 172 slides in the T-groove 171. Each divided piece 131 and 132 has a guide rib 173 that extends in a direction inclined with respect to the sliding direction of the sliding portion 135. The second type 120 has a guide groove 174 (see Figure 4) into which the guide rib 173 fits. The guide groove 174, like the guide rib 173, extends in a direction inclined with respect to the sliding direction of the sliding portion 135. As the guide rib 173 slides within the guide groove 174, the housing portion 133 deforms as the sliding portion 135 slides. Specifically, when the sliding part 135 slides towards the first mold 110, the divided pieces 131 and 132 slide away from each other. Conversely, when the sliding part 135 slides away from the first mold 110, the divided pieces 131 and 132 slide towards each other. In the combined divided pieces 131 and 132, an internal space IS (see Figure 7) is formed to house the exposed portion 50. For this purpose, the divided piece 131 has a recess 181 that matches the outer circumferential surface 51 of the exposed portion 50, and the divided piece 132 has a recess 182 that matches the outer shape of the exposed portion 50. As shown in Figure 10, the recesses 181 and 182 are provided with a recess 184 into which the convex portion 52 of the exposed portion 50 fits. Figure 10 shows a cross-section of the sliding pin 130 and the exposed portion 50 in a plane perpendicular to the sliding direction in the state of Figure 5. The oval shape 185 of the combined divided pieces 131 and 132 matches the shape of the boundary between the embedded portion 40 and the exposed portion 50. Therefore, there is virtually no gap between the embedded portion 40 and the exposed portion 50 and the combined divided pieces 131 and 132, so molten resin does not penetrate into the internal space IS of the combined divided pieces 131 and 132. 【0025】 (4-3) Cylinder Cylinder 160 is an actuator that drives the ejector plate 150 to which the sliding pin 130 and ejector pin 140 are fixed. As shown in Figure 11, controller C1 controls the drive unit D1 that drives the first type 110 and the second type 120, and cylinder 160. The ejector plate 150 changes the ejector stroke St shown in Figure 6 by cylinder 16. Controller C1 can be configured as, for example, a computer (not shown). The computer can use, for example, an MPU or CPU and memory. With the first type 110 and the second type 120 in an open state, the controller C1 instructs the drive unit D1 to start the clamping operation of the first type 110 and the second type 120. Note that the second type 120 does not move during the clamping operation. When the first type 110 and the second type 120 are open, the dividing pieces 131 and 132 are also open. With the dividing pieces 131 and 132 still open, the first type 110 begins to move toward the second type 120. At this time, the controller C1 controls the cylinder 160 so that the ejector plate 150 does not start to move. Next, when the exposed part 50 enters the housing part 133, the controller C1 controls the cylinder 160 to start the movement of the ejector plate 150, and controls the drive unit D1 to continue the movement of the first type 110. At the moment when the upper surfaces (third surface 138) of the divided pieces 131 and 132 reach the boundary between the embedded portion 40 and the exposed portion 50, the controller C1 controls the drive unit D1 and the cylinder 160 to stop the movement of the first mold 110 and the ejector plate 150. This increases the ejector stroke St between the second mold 120 and the ejector plate 150. As the ejector stroke St increases, the guide rib 173 moves along the guide groove 174, narrowing the distance between the divided pieces 131 and 132. As a result, the divided pieces 131 and 132 merge, forming a molding space SP surrounded by the first surface 118, the second surface 128, and the third surface 138, and the mold clamping is completed. As described above, during the mold clamping operation, the operation of the cylinder 160 and the drive unit D1 are synchronized under the control of the controller C1. 【0026】 Mold opening begins after the molten resin has filled the molding space SP and solidified. Starting from a closed state of the first mold 110 and the second mold 120, the mold opening operation of the first mold 110 and the second mold 120 is initiated by an instruction from the controller C1. When the first mold 110 and the second mold 120 are closed, the segmented pieces 131 and 132 are also closed. The cylinder 160 maintains the state it was in when the mold clamping operation was completed until the first mold 110 and the second mold 120 have finished opening. Once the first mold 110 and the second mold 120 have finished opening, the cylinder 160 reduces the ejector stroke St between the second mold 120 and the ejector plate 150. As the ejector stroke St decreases, the guide rib 173 moves along the guide groove 174, causing the distance between the segmented pieces 131 and 132 to widen. As the ejector stroke St decreases, the ejector pin 140 also pushes out the resin molded product 1. As the divided pieces 131 and 132 open and the ejector pin 140 protrudes, the mold opening of the first mold 110 and the second mold 120 is completed. 【0027】 <Second Embodiment> (5) Overall structure In the first embodiment described above, the case in which the sliding pin 130 is fixed to the ejector plate 150 was explained. However, a dedicated plate 155 for sliding the sliding pin 130 may be provided in a location other than the ejector plate 150. In the second embodiment, the main components other than the dedicated plate 155, the ejector plate drive unit 164, the ejector return spring 165, and the dedicated plate return spring 166 are the same as in the first embodiment, so the description of the configurations of the first type 110, the second type 120, and the sliding pin 130 will be omitted. In the second embodiment, the cylinder 160 is an actuator that drives a dedicated plate 155 (see Figure 12) to which the sliding pin 130 is fixed. Figure 12 shows the dedicated plate 155 and other parts of the first type 110 and second type 120 partially cut away and viewed from diagonally above. The ejector plate 150 is driven by the ejector plate drive unit 164. In the second embodiment, the controller C1 controls the drive unit D1 that drives the first type 110 and second type 120, the ejector plate drive unit 164, and the cylinder 160. The ejector plate 150 changes the ejector stroke St shown in Figure 14 by the ejector plate drive unit 164 and the ejector return spring 165. The dedicated plate 155 changes the sliding stroke Di shown in Figure 13 by the cylinder 16 and the dedicated plate return spring 166. Figures 12 to 15 show cross-sections of the first type 110 and the second type 120, and the side views of the sliding pin 130 and ejector pin 140 are also shown. 【0028】 With the first mold 110 and the second mold 2120 in an open state, the mold clamping operation of the first mold 110 and the second mold 2120 is initiated by an instruction from the controller C1 to the drive unit D1. Note that the second mold 2120 does not move during the mold clamping operation. When the first mold 110 and the second mold 2120 are open, the dividing pieces 131 and 132 are also open. First, the first mold 110 begins to move toward the second mold 2120. At this time, the controller C1 controls the cylinder 160 so that the ejector plate 150 does not start to move. With the dividing pieces 131 and 132 still open, the first mold 110 moves toward the second mold 2120. At this time, the ejector plate 150 moves away from the second mold 2120 by the ejector return spring 165. However, the dedicated plate 155 is supported by the cylinder 160 and does not move, remaining stationary relative to the second mold 2120. In other words, the controller C1 controls the drive unit D1 and the cylinder 160, causing the first type 110 and the ejector plate 150 to move and the dedicated plate 155 to remain stationary. Next, when the exposed portion 50 enters the housing portion 133, controller C1 controls cylinder 160 to start moving the dedicated plate 155, and controls drive unit D1 to continue moving the first type 110. When the upper surfaces (third surfaces 138) of the divided pieces 131 and 132 reach the boundary between the embedded portion 40 and the exposed portion 50, controller C1 controls drive unit D1 and cylinder 160 to stop the movement of the first type 110 and the dedicated plate 155. As a result, the sliding stroke Di between the second type 120 and the dedicated plate 155 decreases. At this time, the dedicated plate return spring 166 is stretched. As the sliding stroke Di decreases, the guide rib 173 moves along the guide groove 174, narrowing the distance between the divided pieces 131 and 132. The divided pieces 131 and 132 are joined together to form a molding space SP surrounded by the first surface 118, the second surface 128, and the third surface 138, and the mold clamping is completed. As described above, during the mold clamping operation, the operation of the cylinder 160 and the drive unit D1 are synchronized under the control of the controller C1. 【0029】 The mold opening process begins after the molten resin has filled the molding space SP and solidified. Starting from a closed state, the mold opening operation of the first mold 110 and the second mold 120 is initiated by an instruction from the controller C1. When the first mold 110 and the second mold 120 are closed, the divided pieces 131 and 132 are also closed. When the mold opening operation begins, the first mold 110 opens and the ejector plate 150 moves simultaneously, driven by the drive device D1 controlled by the controller C1. As the ejector plate 150 moves, the ejector return spring 165 is compressed. Pushed by this ejector plate 150, the ejector pin 140 protrudes, and the dedicated plate 155 moves toward the second mold 120. As the ejector plate 150 approaches the second mold 120, the ejector stroke St decreases. Then, when the first type 110 and the second type 120 have finished opening, the ejector stroke St becomes 0. As the ejector stroke St decreases, the guide rib 173 moves along the guide groove 174, causing the spacing between the divided pieces 131 and 132 to widen. As the ejector stroke St decreases, the ejector pin 140 also pushes out the resin molded product 1, as shown in Figure 15. With the divided pieces 131 and 132 opening and the ejector pin 140 pushing out, the mold opening of the first mold 110 and the second mold 120 is completed. 【0030】 <Third Embodiment> (6) Overall structure In the first embodiment described above, the intrusion of molten resin was prevented by substantially eliminating the gap between the third surface 138 formed by the sliding pin 130 and the boundary between the embedded portion 40 and the exposed portion 50. As described in the third embodiment, the intrusion of molten resin may be prevented more by the internal space IS of the housing portion 133 than by the third surface 138. In the third embodiment, the main components other than the sliding pin 130 and the insert member 20 can be configured in the same way as in the first embodiment, so the explanation of the configurations of the first type 110 and the second type 120, as well as the ejector plate 150 and the cylinder 160, will be omitted. Figures 16, 17, 18, 19, and 20 show a connector 200 including a sliding pin 130 and an embedded portion 40 and an exposed portion 50 of an insert member 20. The sliding pin 130 of the third embodiment includes four segmented pieces 231, 232, 233, and 234 and a sliding portion 235. The four segmented pieces 231, 232, 233, and 234 constitute a housing portion 133. The sliding portion 235 of the third embodiment is fixed to the ejector plate 150, as in the first embodiment, or to a dedicated plate 155, as in the second embodiment. The sliding portion 235 slides as the ejector plate 150 or the dedicated plate 155 moves. 【0031】 The sliding portion 235 has a T-groove 171 that extends in a cross shape in plan view for slidably supporting the four segmented pieces 231 to 234. Each segmented piece 231 to 234 has a slider 172 with a T-shaped cross section that fits into the T-groove 171. Each segmented piece 231 to 234 joins together as the slider 172 slides along the T-groove 171, moving from all four sides in directions perpendicular to the sliding direction of the sliding portion 235. Each segmented piece 231 to 234 has a guide rib 173 that extends in a direction inclined with respect to the sliding direction of the sliding portion 235. In the combined divided pieces 231-234, an internal space IS (see Figure 20) is formed for housing the exposed portion 50 inside. To this end, as shown in Figure 18, recesses 281-284 are formed in the divided pieces 231-234 to match the outer circumferential surface 210 of the exposed portion 50. The recesses 281-284 are provided with indentations 285 into which the protrusions 52 of the exposed portion 50 fit. The connector 200 of the insert member 20 has a dam portion 220 on the outer circumferential surface 210 of the exposed portion 50. The dam portion 220 protrudes in an annular shape to dam the molten resin. The divided pieces 231-234 (housing portion 133) have an annular groove portion 250 that allows the exposed portion 50 to move in a direction intersecting the sliding direction and to contact the dam portion 220 in an annular manner. As shown in Figure 20, the upper wall 251 of the groove portion 250 contacts the upper surface 221 of the dam portion 220. Therefore, there is virtually no gap between the exposed portion 50 and the combined divided pieces 231-234, so that the molten resin does not enter the internal space IS of the combined divided pieces 231-234 (housing portion 133). Since the width L1 of the annular dam portion 220 is smaller than the width L2 of the annular groove portion 250, it is easier to tolerate manufacturing tolerances of the connector 200. In this manufacturing method, the area from the upper surface 221 of the dam section 220 to the third surface 138 becomes the boundary between the exposed section 50 and the buried section 40. Electrode terminals 222 are located in the buried section 40. 【0032】 <Fourth Embodiment> (7) Overall structure In the first embodiment described above, the case in which the T-groove 171 of the sliding pin 130 is formed to extend in a direction perpendicular to the sliding direction was explained. However, the T-groove 171 of the sliding pin 130 may be formed to extend in a direction inclined with respect to the sliding direction. In the fourth embodiment, the main components other than the sliding pin 130 are the same as in the first embodiment, so the description of the configurations of the first type 110 and the second type 120 will be omitted. 【0033】 Figures 21, 22, 23, and 24 show the sliding pin 130 and the resin molded body 10. The sliding pin 130 of the fourth embodiment includes two segmented pieces 131 and 132 and a sliding portion 135. The two segmented pieces 131 and 132 constitute the housing portion 133. The sliding portion 135 of the fourth embodiment is fixed to the ejector plate 150, as in the first embodiment, or to a dedicated plate 155, as in the second embodiment. The sliding portion 135 slides as the ejector plate 150 or the dedicated plate 155 moves. In Figure 21, arrow AR1 is the direction of sliding when the mold is opened, and arrow AR2 is the direction of movement of the segmented pieces 131 and 132 when the mold is opened. When the mold is opened, the segmented pieces 131 and 132 move away from the resin molded body 10. In other words, the segmented pieces 131 and 132 move in a direction inclined with respect to the direction perpendicular to the sliding direction. Therefore, the sliding portion 135 has a T-groove 171 that extends in a direction inclined with respect to the direction perpendicular to the sliding direction in a side view, for slidably supporting the divided pieces 131 and 132. As shown in Figure 22, the direction in which the T-groove 171 extends is inclined by an angle An1 with respect to the direction perpendicular to the sliding direction. Also, as shown in Figure 23, the direction in which the slider 172 extends is inclined by an angle An1 with respect to the direction perpendicular to the sliding direction. By moving the divided pieces 131 and 132 in an inclined direction (direction of arrow AR2), they can move without contacting the resin molded body 10, even when the resin molded body 10 is bent, as shown in Figure 21. In addition to such cases, this method can be applied, for example, when the resin molded body 10 has a protrusion that extends beyond the third surface 138, or when there are protrusions other than the exposed portion 50 protruding from the resin molded body 10. 【0034】 <Fifth Embodiment> (8) Overall structure In the first to fourth embodiments described above, the case in which the divided pieces 131, 132 or divided pieces 231 to 234 are composed of parts that can be separated from the sliding parts 135, 235 has been explained. In the first to fourth embodiments, the sliding pins 130 are formed such that the housing part 133 deforms when the sliders 172 of the divided pieces 131, 132 or divided pieces 231 to 234 slide along the T-groove 171. However, the divided pieces do not have to be separable from the sliding parts, and the divided pieces may be connected to the sliding parts. Figures 25, 26, 27, 28, 29, and 30 show the first type 110 and the second type 120 according to the fifth embodiment, and a sliding pin 330 in which a sliding portion 335 is connected to two divided pieces 331 and 332. In other words, the sliding pin 330 of the fifth embodiment has a bifurcated tip with divided pieces 331 and 332 at its tip (see Figures 27 and 28). If no force is applied to the divided pieces 331 and 332, they remain separated from each other. The sliding pin 330 is made of metal. When a force is applied in a direction that brings the divided pieces 331 and 332 closer together, the divided pieces 331 and 332 combine to form an internal space IS (see Figure 30). 【0035】 From the open state to partway through the mold clamping process, the divided pieces 331 and 332 are open, as shown in Figures 25 and 26. Therefore, the exposed portion 50 having the protrusion 52 can be inserted between the divided pieces 331 and 332. As the mold clamping progresses further, the inclined back surfaces 341 and 342 (see Figure 28) of each divided piece 331 and 332 come into contact with the opening edge 125 of the second mold 120. Since the size of the opening edge 125 is substantially equal to the size of the combined divided pieces 331 and 332, as the mold clamping progresses and the sliding pin 330 is drawn into the second mold 120, the divided pieces 331 and 332, pushed by the opening edge 125, move closer to each other. When the mold clamping is complete, the divided pieces 331 and 332 are combined, and the upper surface of the sliding pin 330 becomes the third surface 138 (see Figure 29). Once the first type 110 and the second type 120 have finished opening, the ejector plate 150 is brought closer to the second type 120, causing the ejector pin 140 and the sliding pin 330 to protrude from the second type 120. At this time, the tip of the sliding part 335 of the sliding pin 330 deforms so that the elastic deformation of the sliding part 335 is released, and the divided pieces 331 and 332 open. The recesses 381, 382 and the indentation 384 of the sliding pin 330 have the same configuration as the recesses 181, 182 and the indentation 184 of the sliding pin 130 in the first embodiment. In the fifth embodiment, the same reference numerals are used for components that are the same as in the first embodiment, and their descriptions are omitted. Also, in Figure 25, cross-sections of the first type 110 and the second type 120 are shown, and the side views of the sliding pin 330 and the ejector pin 140 are shown. 【0036】 (9) Variant (9-1) Variation A In the first to fifth embodiments described above, an example was described in which one sliding pin 130, 330 is provided on the second mold 120. However, it is possible to provide multiple exposed parts 50 on a single resin molded product 1. Therefore, multiple sliding pins 130, 330 may be provided on the second mold 120. Also, the sliding pins 130, 330 can be provided on the first mold 110. For example, a dedicated plate 155 and a cylinder 160 can be provided on the first mold 110. 【0037】 (9-2) Variation B In the first to fifth embodiments described above, the case in which the sliding pins 130 and 330 slide in the same direction as the relative movement direction of the first type 110 and the second type 120 was explained. However, the sliding pins 130 and 330 can also be slid in a direction inclined with respect to the relative movement direction of the first type 110 and the second type 120. (9-3) Modification C In the first to fifth embodiments described above, for example, as shown in Figure 31, a case was described in which a part 51a of the outer peripheral surface 51 of the exposed portion 50 and the contact surfaces 181a and 182a of the recesses 181 and 182 come into contact. In this case, by combining the arc-shaped contact surface 181a and the arc-shaped contact surface 182a and making contact with the entire part 51a of the ring-shaped outer peripheral surface 51, the exposed portion 50 can be exposed from the resin molded body 10. However, as shown in Figure 32, a sealing member 400 may be interposed between a part 51a of the outer peripheral surface 51 of the exposed portion 50 and the contact surfaces 181a and 182a of the recesses 181 and 182. As the sealing member 400, for example, heat-resistant rubber, heat-resistant resin film, or metal film can be wrapped around the exposed portion 50. After molding, the sealing member 400 is configured to be removed. In this case as well, the sliding pin 130 changes to a position that forms the third surface 138, and the sliding pin 130 encloses the exposed portion 50 while leaving the embedded portion 40 of the insert member 20 exposed to the molding space SP. However, in this case, the sliding pin 130 alone cannot close the housing portion 133 and seal off the internal space of the housing portion 133 from molten resin flowing in, so the housing portion 133 and the sealing member 400 work together to seal off the internal space of the housing portion 133. 【0038】 (9-4) Modification D In the first to fifth embodiments described above, the sliding pins 130 and 330 were described in cases where a portion of them was divided into pieces 131, 132, 231, 232, 233, 234, or 331, 332. In these sliding pins 130 and 330, the sliding of one sliding portion 135, 335 causes the divided pieces 131, 132, 231-234, and 331, 332 to deform. However, the sliding pin 530 can also be configured to have two sliding parts 535a and 535b, as shown in Figures 33 and 34. In the sliding pin 530, the divided part 531 is integrally formed with the sliding part 535a, and the divided part 532 is integrally formed with the sliding part 535b. The housing part 533 is composed of two divided parts 531 and 532. The sliding parts 535a and 535b of the sliding pin 530 slide in different directions from each other. When the sliding part 535a slides in the direction of arrow AR3, the divided part 531 moves in the direction of arrow AR5. When the sliding part 535b slides in the direction of arrow AR4, the divided part 532 moves in the direction of arrow AR6. In other words, as the sliding parts 535a and 535b slide toward the divided parts 531 and 532, the two divided parts 531 and 532 move toward each other. The state shown in Figures 33 and 34 is one in which the two divided parts 531 and 532 are joined together, and the upper surfaces of the divided parts 531 and 532 form the third surface 138. By joining the divided parts 531 and 532, the recesses 181 and 182 come together to form a space that accommodates the exposed part 50 (see Figure 31). (9-5) Modification E Figure 35 shows a modified example E of the connector 200. The difference between the modified example E and the connector 200 of the third embodiment (see Figure 19) is that a part of the embedded portion 40, which is the contact surface with the resin molded body, has an uneven shape 223, which increases the grip. In the connector 200 shown in Figure 35, the uneven shape 223 is formed on the flat portion 224 where the electrode terminals 222 are formed. However, the location where the uneven shape 223 is formed is not limited to the flat portion 224, but can be anywhere on the embedded portion 40. By having the uneven shape 223 on the embedded portion 40, the grip of the embedded portion 40 on the resin molded body 10 is increased, and the fixing strength of the connector 200 to the resin molded body 10 can be improved. 【0039】 (10) Features (10-1) In the manufacturing method of the resin molded product 1 described in the first to fifth embodiments above, the sliding pins 130 and 330 deform to enclose the exposed portion 50. Therefore, even if the shape of the exposed portion 50 is complex, for example, having a protrusion 52, the exposed portion 50 can be exposed to the outside of the resin molded body 10, while the embedded portion 40 can be embedded inside the resin molded body 10. Thus, a resin molded product 1 having an insert member 20 including the exposed portion 50 and the embedded portion 40 can be easily manufactured. In the resin molded product 1 manufactured in this way, the embedded portion 40 and the exposed portion 50 are firmly supported by the resin molded body 10, and the area around the boundary between the embedded portion 40 and the main body portion 30 is sealed by the resin molded body 10. 【0040】 (10-2) In the manufacturing method of the resin molded product 1 described above, in the second step S2, the exposed portion 50 is housed in the housing portions 133, 333 of the open sliding pins 130, 330 in synchronization with the mold clamping operation, and the housing portions 133, 333 are deformed into a closed state to enclose the exposed portion 50. Then, by deforming the housing portions 133, 333 into a closed state, a third surface 138 is formed, and in the third step S3, a part of the outer surface of the resin molded product 10 is formed by the third surface 138 without allowing molten resin to flow into the inside of the housing portions 133, 333. Furthermore, in the fourth step S4, the closed housing portions 133, 333 are deformed into an open state, and the exposed portion 50 is removed from the housing portions 133, 333. By configuring the manufacturing method for the resin molded product 1 in this way, the housing section can be transformed from an open state to a closed state in synchronization with the mold clamping operation, thereby utilizing the mold clamping operation of the first mold 110 and the second mold 120 to change the sliding pins 130 and 330, and the manufacturing process and manufacturing equipment can be simplified. 【0041】 (10-3) In the manufacturing method of the resin molded product 1 described above, the housing portion 133 for the sliding pin 130 includes a plurality of divided pieces 131, 132 or divided pieces 231 to 234. The plurality of divided pieces 131, 132 or divided pieces 231 to 234 slide and combine to deform into a closed state when the exposed portion 50 is housed inside the housing portion 133 in the second step S2. The plurality of divided pieces 131, 132 or divided pieces 231 to 234 separate to deform into an open state when the exposed portion 50 is removed from the housing portion 133 in the fourth step S4. In this manufacturing method of the resin molded product 1, since the housing portion 133 consists of a plurality of divided pieces 131, 132 or divided pieces 231 to 234, it is easy to form the housing portion 133 to match the shape of the exposed portion 50. 【0042】 (10-4) In the method for manufacturing the resin molded product 1 described with reference to Figures 21 to 24, the multiple segmented pieces 131, 132 or segmented pieces 231 to 234 can be configured to slide away from the resin molded body 10 when separated. In the method for manufacturing the resin molded product 1 configured in this way, the influence of the sliding pin 130 on the resin molded product 1 during sliding can be reduced. For example, the sliding pin 130 becomes less likely to rub against the resin molded body 10 during sliding, and it becomes easier to form a portion that protrudes from the third surface 138 of the resin molded body 10 towards the sliding portion 135. 【0043】 (10-5) In the manufacturing method of the resin molded product 1 described with reference to Figures 16 to 20, the exposed portion 50 has an annularly protruding dam portion 220 on its outer surface 210 that blocks molten resin. The housing portion 133 has an annular groove portion 250 that allows the exposed portion 50 to move in a direction intersecting the sliding direction and to contact the dam portion 220 in an annular manner. In a manufacturing method of the resin molded product 1 with such a configuration, for example, even if the difference in movement is between the width L1 of the dam portion 220 and the width L2 of the annular groove portion 250, resin intrusion can be prevented, so the tolerance for dimensional errors of the insert member 20 can be increased. In the resin molded product 1 having a dam section 220, the resin molded body 10 is in contact with the dam section 220. 【0044】 <Sixth Embodiment> (11) Overall structure In the third embodiment described above, the case was described in which the insert member 20 is composed of a main body 30 and a connector 200, and the embedded portion 40 and the exposed portion 50 are included in the connector 200. However, the member including the embedded portion 40 and the exposed portion 50 may be a plate-shaped connecting terminal 600 shown in Figures 36, 37, 38 and 39A (sixth embodiment). The connecting terminal 600 shown in Figures 36 to 39A is, for example, a terminal formed by bending a metal plate. Examples of metal materials for the plate include copper, brass, phosphor bronze, iron, and stainless steel. The connecting terminal 600 has a connecting portion 601 and a rising portion 602 that intersect each other with a bent portion 603 in between. Figure 36 shows a connecting terminal 600 bent at a right angle, but the bending angle may be obtuse or acute. When the main body 30 is a film substrate having an electrical circuit, the connection portion 601 of the connection terminal 600 is the part that connects to the electrical circuit. This connection portion 601 is fixed to the main body 30. For example, the connection portion 601 is fixed to the main body 30 with solder and electrically connected. The rising portion 602 of the connection terminal 600 is the part that connects to, for example, an electrical device outside the film substrate. The rising portion 602 rises in a direction that intersects with the surface of the main body 30 to which the connection portion 601 is fixed. In the connection terminal 600 shown in Figure 36, the connection portion 601 and the rising portion 602 are perpendicular to each other. The direction in which the rising portion 602 extends coincides, for example, with the sliding direction of the sliding pin 130. In the sixth embodiment of the connection terminal 600, the connection portion 601 and a part of the rising portion 602 become the buried portion 40, and the other part of the rising portion 602 becomes the exposed portion 50. In the sixth embodiment, the exposed portion 50 is included in the connection terminal 600. A protrusion 52 is provided at the tip 604 of the rising section 602 (see Figure 37). The protrusion 52 is the portion of the rising section 602 that protrudes in the width direction (direction DR3) from the main section 605. The main section 605 is the portion of the rising section 602 excluding the portion on which the protrusion 52 is provided, with a part of the main section 605 included in the buried section 40 and the other part of the main section 605 included in the exposed section 50. Here, the width direction (direction DR3) is the direction perpendicular to the thickness direction (direction DR2) of the rising section 602, and is the direction perpendicular to the upright direction (direction DR1) from the bent section 603 toward the tip 604. 【0045】 In the sixth embodiment, a resin molded product 1 having the connection terminal 600 shown in Figure 39A can be manufactured using a mold similar to the mold 100 of the first embodiment, which is equipped with a sliding pin 130. For comparison, Figure 39B shows a resin molded product 1 having a connector 200 according to the third embodiment. As shown in Figures 1, 39A, and 39B, the resin molded product 1 of the sixth embodiment comprises a resin molded body 10 and an insert member 20, similar to the resin molded product 1 of the first and third embodiments. In the sixth embodiment, in order to simplify the explanation, the configuration of the insert member 20, which has a different shape from the resin molded product 1 of the first and third embodiments, has been mainly described. Regarding the resin molded product 1, there are parts that are the same as the same components that are denoted by the same reference numerals in the first and third embodiments and the sixth embodiment, and their descriptions have been omitted in order to avoid repeating the same explanation. 【0046】 Furthermore, the mold of the sixth embodiment can be configured to include a first mold 110, a second mold 120, a sliding pin 130, and an ejector pin 140, similar to the mold 100 of the first embodiment (see Figure 4). In addition, the mold of the sixth embodiment can be configured to include an ejector plate 150 and a cylinder 160. In the sixth embodiment, in order to simplify the explanation, the configuration of the sliding pin 130, which has a different shape from the sliding pin 130 of the mold 100 of the first embodiment, will be described mainly. Regarding the sliding pin 130, there are parts of the same component that are given the same reference numerals in the first embodiment and the sixth embodiment that have been omitted from the explanation in order to avoid repeating the same explanation. In the sixth embodiment, the housing portion 133 that accommodates the exposed portion 50 includes divided pieces 131 and 132, similar to the first embodiment. Each divided piece 131 and 132 has recesses 181 and 182 formed therein. Since the shape of the exposed portion 50 in the first embodiment is different from the shape of the exposed portion 50 in the sixth embodiment, the shapes of the recesses 181 and 182 in the first embodiment are different from the shapes of the recesses 181 and 182 in the sixth embodiment. The shape of the recesses 181 and 182 in the sixth embodiment consists of normal width portions 181m and 182m corresponding to the main portion 605 and wider portions 181n and 182n that are wider than the normal width portions 181m and 182m (see Figures 37 and 38). The width of the wider portions 181n and 182n is greater than or equal to the width of the portion where the convex portion 52 is formed. The wider portions 181n and 182n correspond to the recess 184 in the first embodiment. The resin molded product 1 of the sixth embodiment can be manufactured by applying the same manufacturing method as the resin molded product 1 of the first embodiment. Because of the protrusion 52, when the divided pieces 131 and 132 are joined together, the connecting terminal 600 cannot be pulled out from the hole formed by the joining of the normal width sections 181m and 182m. However, as described in the first embodiment, the sliders 172 of the divided pieces 131 and 132 slide along the T-groove 171 of the sliding portion 135 and separate, allowing the connecting terminal 600 to be removed from the recesses 181 and 182. Furthermore, in the sixth embodiment, the divided pieces 131 and 132 are provided with a fitting groove 186 on the divided piece 131 and a fitting projection 187 on the divided piece 132 in order to suppress relative misalignment when the divided pieces 131 and 132 are joined together. By fitting the fitting projection 187 into the fitting groove 186 and making contact, it is possible to suppress misalignment between the divided pieces 131 and 132 when they are joined together. 【0047】 (12) Modification F In the sixth embodiment, the case in which the protrusion 52 is located on the tip 604 of the connection terminal 600 was described. However, the location where the protrusion 52 is located may be other than the tip 604 of the exposed portion 50. For example, the protrusion 52 may be located in the middle of the exposed portion 50 on the rising portion 602. Also, although the case in which one protrusion 52 is provided on one side of one rising portion 602 was described, the protrusion 52 may be provided on both sides of one rising portion 602. Furthermore, in the sixth embodiment, the case in which the width of the protrusion 52 protruding from the main portion 605 is constant at all locations was described. However, the shape of the protrusion 52 may be such that the protrusion width differs depending on the location of the protrusion 52, for example, like a sine curve. Furthermore, in the sixth embodiment, the case in which the protrusion 52 protrudes in the width direction of the plate-shaped connector 600 was described. However, the protrusion may also protrude in the thickness direction of the plate-shaped connector 600, although this is not shown in the figures. For example, the protrusion can be formed by bending the tip 604 of the plate-shaped connector 600. 【0048】 (13) Variation G In the sixth embodiment, a case was described in which a resin molded product 1 is formed using a connecting terminal 600 having a protrusion 52. However, a mold and a manufacturing method having similar technical characteristics can be applied to a resin molded product and its manufacture using a connecting terminal 690 without a protrusion 52, as shown in Figure 40. The connecting terminal 690 shown in Figure 40 is the same as the connecting terminal 600 shown in Figure 37 in that it has a connecting portion 601 and a rising portion 602. However, the rising portion 602 in Figure 40 has a constant width and does not have a protrusion 52. Therefore, the divided pieces 131 and 132 of the sliding pin 130 in Figure 40 do not have the wide portions 181n and 182n shown in Figures 37 and 38, in order to accommodate the exposed portion 50 of the connecting terminal 690 which does not have the protrusion 52. 【0049】 <Seventh Embodiment> (14) Overall structure In the sixth embodiment described above, the case in which the connection terminal 600 is formed by bending a metal plate, for example, was explained. However, as shown in Figures 41 to 44, the shape of the connection terminal 700 may be, for example, a pin shape having a protrusion 52. The connection terminal 700 is, for example, made of metal. Examples of materials for the metal connection terminal 700 include copper, brass, phosphor bronze, iron, and stainless steel. The connection terminal 700 of the seventh embodiment shown in Figures 41 to 44 has a disc-shaped connection portion 701 and a rising portion 702. The tip portion 704 of the rising portion 702 is processed into a disc shape and has a protrusion 52 formed thereon. The portion of the rising portion 702 excluding the disc-shaped tip portion 704 is a cylindrical main portion 705. The buried portion 40 includes the disc-shaped connection portion 701 and a part of the cylindrical main portion 705, and the exposed portion 50 includes the other part of the cylindrical main portion 705. The protruding portion 52 is included in the exposed portion 50. If the main body 30 is a film substrate having an electrical circuit, the connection portion 701 of the connection terminal 700 is the part that connects to the electrical circuit. This connection portion 701 is fixed to the main body 30. For example, the connection portion 701 is fixed to the main body 30 with solder and electrically connected. The rising portion 702 of the connection terminal 700 is the part for connecting to, for example, an electrical device outside the film substrate. The rising portion 702 rises in a direction intersecting the surface of the main body 30 to which the connection portion 701 is fixed. In the connection terminal 700 shown in Figure 41, the central axes of the disc-shaped connection portion 701 and the cylindrical main body 705 are aligned with each other. The direction in which the rising portion 702 extends coincides, for example, with the sliding direction of the sliding pin 130. 【0050】 In the seventh embodiment, a resin molded product 1 having a connecting terminal 700 as shown in Figure 44 can be manufactured using a mold similar to the mold 100 of the first embodiment, which includes a sliding pin 130. As shown in Figures 1 and 44, the resin molded product 1 of the seventh embodiment comprises a resin molded body 10 and an insert member 20, similar to the resin molded product 1 of the first embodiment. In the seventh embodiment, in order to simplify the explanation, the configuration of the insert member 20, which has a different shape from the resin molded product 1 of the first embodiment, has been mainly described. Regarding the resin molded product 1, there are parts that are the same as the same components that are given the same reference numerals in the first embodiment and the seventh embodiment, and their descriptions have been omitted to avoid repeating the same explanation. Furthermore, direction DR1 shown in Figure 42 is the upright direction of the rising section 702, and is the direction in which the central axis of the rising section 702 extends. Directions DR2 and DR3 are the radial directions of the rising section 702. Direction DR2 is the direction of movement of the divided pieces 131 and 132, and direction DR3 is the direction perpendicular to direction DR2. 【0051】 The mold of the seventh embodiment can be configured to include a first mold 110, a second mold 120, a sliding pin 130, and an ejector pin 140, similar to the mold 100 of the first embodiment (see Figure 4). Furthermore, the mold of the seventh embodiment can be configured to include an ejector plate 150 and a cylinder 160. In the seventh embodiment, in order to simplify the explanation, the configuration of the sliding pin 130, which has a different shape from the sliding pin 130 of the mold 100 of the first embodiment, will be described mainly. Regarding the sliding pin 130, there are parts of the same component that are given the same reference numerals in the first embodiment and the seventh embodiment that have been omitted from the explanation to avoid repeating the same explanation. In the seventh embodiment, the housing portion 133 that accommodates the exposed portion 50 includes divided pieces 131 and 132, similar to the first embodiment. Each divided piece 131 and 132 has a recess 181 and 182 formed therein. Since the shape of the exposed portion 50 in the first embodiment is different from the shape of the exposed portion 50 in the seventh embodiment, the shapes of the recesses 181 and 182 in the first embodiment are different from the shapes of the recesses 181 and 182 in the seventh embodiment. The shape of the recesses 181 and 182 in the seventh embodiment includes semi-cylindrical first portions 181p and 182p corresponding to the main portion 705, and second portions 181q and 182q which are shaped like a disk with a larger diameter than the semi-cylindrical first portions 181p and 182p, cut in half by a plane passing through the central axis. The radii of the second portions 181q and 182q are greater than or equal to the radius of the disk-shaped tip portion 704. The second parts 181q and 182q correspond to the recess 184 in the first embodiment. In the seventh embodiment, third parts 181r and 182r are provided in the recesses 181 and 182, into which the connection terminals 700 do not fit. However, the configuration may be made without these third parts 181r and 182r. The resin molded product 1 of the seventh embodiment can be manufactured by applying the same manufacturing method as the manufacturing method of the resin molded product 1 of the first embodiment. Because of the protrusion 52, when the divided pieces 131 and 132 are joined together, the connecting terminal 700 cannot be pulled out from the hole formed by the joining of the first parts 181p and 182p. However, as described in the first embodiment, the sliders 172 of the divided pieces 131 and 132 slide along the T-groove 171 of the sliding part 135 and separate, allowing the connecting terminal 700 to be removed from the recesses 181 and 182. Furthermore, the divided pieces 131 and 132 of the seventh embodiment are also provided with fitting grooves 186 and fitting projections 187, similar to those of the sixth embodiment. 【0052】 (15) Variation H In the seventh embodiment, the case in which the protrusion 52 is located on the tip 704 of the connection terminal 700 was described. However, the location where the protrusion 52 is located may be other than the tip 704 of the exposed portion 50. For example, the protrusion 52 may be located in the middle of the exposed portion 50 on the rising portion 702. Also, in the seventh embodiment, the case in which the radius of the protrusion 52 is constant at all locations was described. However, the shape of the exposed portion 50 with the protrusion 52 may be, for example, a barrel shape that gradually widens towards the center. 【0053】 (16) Variation I In the seventh embodiment, a case was described in which a resin molded product 1 is formed using a connecting terminal 700 having a protrusion 52. However, a mold and a manufacturing method having similar technical characteristics can be applied to a resin molded product and its manufacture using a connecting terminal 790, which does not have a protrusion 52, as shown in Figure 45. The connecting terminal 790 shown in Figure 45 is the same as the connecting terminal 700 shown in Figure 41 in that it has a connecting portion 701 and a rising portion 702. However, the rising portion 702 in Figure 44 is cylindrical with a constant radius and does not have a protrusion 52. Therefore, the divided pieces 131 and 132 of the sliding pin 130 in Figure 44 do not have the second parts 181q and 182q shown in Figures 42 and 43, in order to accommodate the exposed portion 50 of the connecting terminal 790 which does not have the protrusion 52. Although the first to seventh embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications are possible without departing from the spirit of the invention. In particular, the multiple embodiments and modifications described herein can be arbitrarily combined as needed.
