The third and fourth slice portions are positioned and held in the cavity by holding the proximal end portions of the first and second slice portions by the first and second molds. In other words, the first and second slice portions for positioning and holding the third and fourth slice portions in the cavity are indispensable, and therefore the terminal system is increased in size. Therefore, it is difficult to miniaturize the resin molded article.

The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a resin molded article in which a slice portion of a terminal can be easily positioned and held in a cavity of a first and a second mold. A molded mold for miniaturization, a method for producing a resin molded article using the mold, and a resin molded article.

In order to solve the above problems, the molding die of the present invention includes first and second molds, and the first and second molds have cavities that can accommodate at least a slicing portion of the terminal. The first mold has a convex portion that can abut against the first surface of the slicing portion, and a projection that is provided at a distance from the convex portion. The protrusion has a first edge that is in contact with the second surface on the side opposite to the first surface of the sliced portion and an edge that is the end side of the protrusion. The second edge and the inclined surface which is inclined so as to be away from the convex portion from the first edge to the second edge or the curved surface which is curved.

In the case of the molding die of this type, the first surface of the sliced portion of the terminal is brought into contact with the convex portion of the first mold, and the second surface of the sliced portion is brought into contact with the projection of the first mold. The first edge. Thereby, since the slicing portion is held by the convex portion of the first mold and the first edge of the protrusion, the slice portion of the terminal can be easily positioned and held in the cavity of the first and second molds. . Further, since the slicing portion is held by the convex portion of the first mold and the first edge of the projection, it is possible to cause The movement or deformation of the terminal caused by the injection pressure when the resin is ejected from the cavity is suppressed. Further, it is not necessary to separately provide a portion for positioning and holding the slicing portion in the cavity of the first and second molds at the terminal. Therefore, since the terminal system is not enlarged, it is possible to reduce the size of the resin molded article. Further, since the slicing portion is guided between the convex portion of the first mold and the first edge of the projection by the inclined surface or the curved surface, the slicing portion can be easily inserted into the convex portion of the first mold and Between the first edges of the protrusions. Further, the inclined surface of the projection is inclined so as to be away from the slicing portion. Further, the curved surface of the protrusion is curved so as to be away from the sliced portion. In other words, since a space which is a part of the cavity is formed between the second surface of the slicing portion and the inclined surface of the projection or the curved surface, the resin can flow into the space. Therefore, even if the second surface of the slicing portion is brought into contact with the projection, the second surface can be buried in the resin.

The first and second molds may be configured such that the terminal body capable of accommodating the terminal and the terminal body connected to the terminal body and bent with respect to the terminal body are formed in the cavity Slice section.

In the case of the molding die of this form, since the slicing portion is bent at a substantially right angle with respect to the terminal body, it is susceptible to the injection pressure when the insulating resin is injected into the cavity. However, since the slicing portion is held by the first edge of the convex portion and the projection, it is possible to suppress the movement or deformation of the slice portion of the terminal due to the above-described injection pressure.

The first and second molds may be configured such that the terminal body can be housed in the cavity and partially held.

In the case of the molding die of this type, since the first and second molds are held in the cavity and the terminal body is held, the terminal can be moved due to the injection pressure when the resin is ejected into the cavity or The case of deformation is further suppressed.

The method for producing a resin molded article of the present invention is a method for producing a resin molded article by using the above-described molding die. In this method, the slice portion of the terminal is inserted between the convex portion of the first mold and the protrusion, and the first surface of the slice portion is brought into contact with the convex portion to make the second surface The first edge of the protrusion is brought into contact with the protrusion, and the slice portion is held by the protrusion and the first edge.

The insulating resin is injected and hardened to the cavity, and the sliced portion is buried in the insulating resin.

In the case of the manufacturing method of this aspect, it is only necessary to insert the sliced portion of the terminal between the convex portion and the projection of the first mold, and the first portion of the convex portion and the first edge of the projection can be held by the first edge. Slice section. Therefore, it is possible to easily position and hold the sliced portion of the terminal in the cavity of the first and second molds. Further, since the slicing portion is held by the convex portion of the first metal mold and the first edge of the projection, it is possible to cause the movement or deformation of the terminal due to the injection pressure when the resin is ejected to the cavity. inhibition. Also, it does not need to be set at the terminal to slice The portion is positioned and held in the cavity of the first and second molds. Therefore, since the terminal system is not enlarged, it is possible to reduce the size of the resin molded article. Further, the insulating resin that is injected into the cavity flows into the space between the second surface of the slicing portion and the inclined surface or the curved surface of the projection. Therefore, even if the second surface of the slicing portion is brought into contact with the projection, the second surface can be buried in the resin.

When the sliced portion of the terminal is disposed in the cavity of the first and second molds, the terminal body of the terminal can be connected to the terminal body and made relative to the terminal body. The sliced portion that is bent is disposed in the cavity.

In the case of the manufacturing method of this aspect, since the slicing portion is bent at a substantially right angle with respect to the terminal body, it is susceptible to the influence of the injection pressure when the insulating resin is injected into the cavity. However, since the slicing portion is held by the first edge of the convex portion and the projection, it is possible to suppress the movement or deformation of the slice portion of the terminal due to the above-described injection pressure.

The first and second molds may be configured such that the terminal body can be housed in the cavity and partially held.

In the case of the manufacturing method of this aspect, since the first and second molds are held in the cavity and the terminal body is held, the terminal can be moved or deformed due to the injection pressure when the resin is ejected into the cavity. The situation is further suppressed.

In this manner, the terminals 200a, 200b, and 200c are inserted into the body portion 100 (first insulating resin R1).

Specifically, the terminal bodies 210a, 210b, 210c are embedded in the base 110 of the body 100. Thereby, the first faces 211a, 211b, and 211c of the terminal bodies 210a, 210b, and 210c are partially exposed from the first surface 111 of the body portion 100. The second surface 212a of the terminal body 210a is partially exposed from the branch portion 142 of a part of the concave portion 140 of the body portion 100. The second faces 212a and 212b of the terminal bodies 210a and 210b are partially exposed from the other branch portions 142 of the recess 140 of the body portion 100. The second faces 212a and 212c of the terminal bodies 210a and 210c are partially exposed from the remaining branch portions 142 of the recesses 140 of the body portion 100. Portions other than the front end portions of the connecting portions 250a, 260a, 220b, and 220c are embedded in the base body 110 of the body portion 100, and the front end portion protrudes beyond the body portion 100. The slicing portions 220a, 230a, 240a are embedded in the side wall 120 of the body 100. Thereby, the first faces 221a, 231a, and 241a of the slicing portions 220a, 230a, and 240a are exposed from the wall surface 121 of the side wall 120. The second faces 222a, 232a, and 242a of the slicing portions 220a, 230a, and 240a are in contact with the first edges 131a, 131b, and 131c of the recessed portions 130a, 130b, and 130c, and are inclined faces of the recessed portions 130a, 130b, and 130c.

Thereafter, the first and second dies 10 and 20 are released from the mold, and the body 100 and the terminals 200a, 200b, and 200c are taken out.

Thereafter, the body 100 and the terminals 200a, 200b, The 200c is housed in the cavity C2 of the third and fourth molds 30 and 40, and the concave portion 140 of the body 100 is closed by the fourth mold. Thereby, the space is defined by the fourth mold 40 and the concave portion 140 of the body portion 100. Thereafter, the second insulating resin R2 is ejected from the runner 14 for the space, and is filled in the space (the recess 140). Thereafter, the second insulating resin R2 is cured. In this manner, the second insulating resin R2 is molded as the sealing portion 300. Thereby, the sealing portion 300 is fixed to the body portion 100 and the terminals 200a, 200b, and 200. Thereafter, the third and fourth molds 30 and 40 are released from the mold, and the body 100, the terminals 200a, 200b, and 200c and the sealing portion 300 are taken out. A resin molded article was produced as described above.

In the case of the above-described resin molded article, the slicing portion 220a is held between the convex portion 11 of the first metal mold 10 and the first edge 13a1 of the projection 13a during the molding of the body portion 100. The slicing portion 230a is held between the convex portion 11 of the first mold 10 and the first edge 13b1 of the projection 13b. The slicing portion 240a is held between the convex portion 11 of the first mold 10 and the first edge 13c1 of the projection 13c. Further, the terminal bodies 210a, 210b, and 210c are held between the convex portion 11 of the first mold 10 and the projections 22 of the second mold 20. Therefore, since the terminal 200a can be easily positioned and held in the cavity C1, the terminal 200a can be miniaturized and the resin can be obtained as compared with the case where the positioning holding portion is separately provided at the terminal 200a. The miniaturization of the molded article. Further, since the slicing portions 220a, 230a, and 240a are bent at a right angle with respect to the terminal body 210a, they are easily exposed to the cavity C1. 1 The influence of the injection pressure when insulating resin R1. However, since the slicing portions 220a, 230a, and 240a are held by the convex portion 11 and the first edge of the projection as described above, the slicing portion 220a of the terminals 200a, 200b, and 200c due to the above-described ejection pressure can be applied. The movement or deformation of 220b, 220c is suppressed. Further, since the slicing portion 220a is guided between the convex portion 11 and the first edge 13a1 of the projection 13a by the inclined surface 13a3 of the first mold 10, the slicing portion 220a can be easily inserted into the convex portion 11 Between the first edge 13a1 and the first edge 13a1. In this regard, the slicing portions 230a and 240a are also the same.

Further, the inclined faces 13a3, 13b3, and 13c3 of the projections 13a, 13b, and 13c of the first die 10 are inclined so as to be apart from the convex portion 11. If the slicing portions 220a, 230a, 240a are held between the convex portions 11 and the first edges 13a1, 13b1, 13c1 of the projections 13a, 13b, 13c, the inclined surfaces 13a3, 13b3, 13c3 and the slicing portions 220a, 230a are formed. A space which is a part of the cavity C1 is formed between the second faces 222a, 232a, and 242a of the 240a. Since the first insulating resin R1 can flow into the space, the second faces 222a, 232a, and 242a of the slice portions 220a, 230a, and 240a and the first edges 13a1 and 13b1 of the projections 13a, 13b, and 13c are formed. When 13c1 is in contact with each other, the second faces 222a, 232a, and 242a can be buried in the resin.

Further, during the molding of the body portion 100, the terminals 200a, 200b, and 200c are held between the convex portion 11 of the first mold 10 and the projection 22 of the second mold 20. Therefore, at the second surface 112 of the body portion 100, a concave portion 140 corresponding to the outer shape of the protrusion 22 is formed. in In the recessed portion 140, the sealing portion 300 is filled. Therefore, the insulation property, water repellency, and dustproofness of the resin molded article can be improved without increasing the thickness of the resin molded article. Further, since the sealing portion 300 is filled in the concave portion 140 and fixed to the body portion 100 and the terminals 200a, 200b, and 200c, it is difficult to peel off.

Further, the concave portion 140 has a shape including a center portion 141 and a plurality of branch portions 142 extending radially from the center portion 141. The branch portion 142 is elongated as long as the above. Therefore, when the second insulating resin R2 is emitted into the center portion 141 during the molding of the sealing portion 300, the second insulating resin R2 flows from the center portion 141 to the branch portion 142. In other words, since the fluidity of the second insulating resin R2 is improved, the second insulating resin R2 (the sealing portion 300) can be easily filled in the concave portion 140.
