[0037] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on another element or there can be one or more centered elements therebetween. When an element is described as "connected" to another element, it can be directly connected to another element or there can be one or more centered elements therebetween. The orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "vertical", "horizontal", etc. used in this specification is based on the orientation or positional relationship shown in the accompanying drawings, only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0038] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0039] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0040] In order to make it easier for readers to understand the structure and function of the mold in this application, the plastic product 200 formed by using the mold in this application is first introduced. Figure 1 The plastic product 200 includes a first plastic part 2002, a second plastic part 2003 and a metal wire 2001. The first plastic part 2002 and the second plastic part 2003 are respectively arranged at the two ends of the metal wire 2001, and the metal wire 2001 is generally bent and extended. The plastic product 200 is generally used in bone conduction headphones. When the plastic product 200 is formed by using a mold, it is necessary to respectively set a wiring groove on the upper mold body and the lower mold body of the mold to accommodate the metal wire 2001. Before the upper mold body and the lower mold body are molded together, the metal wire 2001 is first placed in the wiring groove of the lower mold body, and then the upper mold body and the lower mold body are molded together, and then plastic is injected into the mold to form the first plastic part 2002 and the second plastic part 2003. However, since the diameter of the metal wire 2001 is generally less than 3 mm, it brings great difficulty for workers to place the metal wire 2001 in the wiring groove of the lower mold body, thereby affecting the production efficiency of the plastic product 200. In addition, the metal wire 2001 is generally bent and extended, and due to errors in manufacturing, when the metal wire 2001 is placed in the wiring groove of the lower mold body, it is easy for the metal wire 2001 to produce bending stress. The bending stress can easily separate the metal wire 2001 from the wiring groove of the lower mold body, thereby easily affecting the smooth mold closing between the upper mold body and the lower mold body, and further affecting the molding of the plastic product 200.

[0041] The mold of this application is introduced below.

[0042] See also Figure 1 and Figure 2 The mold 100 includes: a lower mold body 1, an upper mold body 2 and a spring-pressing component 3. The spring-pressing component 3 is installed on the upper mold body 2. When the upper mold body 2 and the lower mold body 1 are molded together, the spring-pressing component 3 can press the metal wire 2001 to reduce the risk of the metal wire 2001 moving during the injection molding process.

[0043] For the lower mold body 1 mentioned above, please refer to Figures 3 to 6The lower mold body 1 is provided with a first receiving groove 101, a first cavity 102, a second cavity 103, a first boss 104, a second boss 105, a third boss 106, a fourth boss 107, a first guide platform 108, a second guide platform 109, a third guide platform 110 and a fourth guide platform 111. The first receiving groove 101 is bent and extended, one end of the first receiving groove 101 is connected to the first cavity 102, and the other end of the first receiving groove 101 is connected to the second cavity 103. The first boss 104 and the second boss 105 are respectively located on both sides of the first receiving groove 101, and the first boss 104 and the second boss 105 are opposite. The third boss 106 and the fourth boss 107 are respectively located on both sides of the first receiving groove 101, and the third boss 106 and the fourth boss 107 are opposite, and the third boss 106 and the first boss 104 are arranged at intervals, and the fourth boss 107 and the second boss 105 are arranged at intervals. Before the upper mold body 2 and the lower mold body 1 are molded together, the metal wire 2001 is placed in the first receiving groove 101, wherein the length of the metal wire 2001 is greater than the length of the first receiving groove 101, and one end of the metal wire 2001 extends into the first cavity 102, and the other end of the metal wire 2001 extends into the second cavity 103. Under the restriction of the first boss 104 and the second boss 105 and the restriction of the third boss 106 and the fourth boss 107, the risk of the metal wire 2001 escaping from the first receiving groove 101 under the action of bending stress can be reduced, thereby ensuring that the upper mold body 2 and the lower mold body 1 can be molded together smoothly. The first guide platform 108 and the second guide platform 109 are respectively located on both sides of the first receiving groove 101, one end of the first guide platform 108 is connected to one end of the first boss 104, and one end of the second guide platform 109 is connected to one end of the second boss 105. The first boss 104 is provided with a first inclined surface 1081, and the second boss 105 is provided with a second inclined surface 1091. The first inclined surface 1081 and the second inclined surface 1091 are opposite to each other, and the first inclined surface 1081 and the second inclined surface 1091 jointly form a first guide groove 112. Figure 7 and Figure 8 , Figure 7 It is a schematic diagram of the cross-sectional structure of the lower mold body 1 at the first cross section. In the first cross section, the first guide groove 112 is V-shaped, the first guide groove 112 is connected to the first receiving groove 101, and the opening of the first guide groove 112 faces the upper mold body 2. The first guide groove 112 is used to guide the metal wire 2001 to be loaded into the first receiving groove 101, so as to facilitate the placement of the metal wire 2001 in the first receiving groove 101, wherein the first cross section is located between one end of the first guide platform 108 and the other end of the first guide platform 108, and the first cross section is perpendicular to the extension direction of the first receiving groove 101. Please refer to Figure 6The third guide platform 110 and the fourth guide platform 111 are respectively located on both sides of the first receiving groove 101. One end of the third guide platform 110 is connected to one end of the third boss 106, and one end of the fourth guide platform 111 is connected to one end of the fourth boss 107. The third guide platform 110 is provided with a third inclined surface 1101, and the fourth guide platform 111 is provided with a fourth inclined surface 1111. The third inclined surface 1101 and the fourth inclined surface 1111 are opposite to each other, and the third inclined surface 1101 and the fourth inclined surface 1111 jointly form a second guide groove 113. Please refer to Fig. 9 and Fig.10 , Fig. 9 It is a schematic diagram of the cross-sectional structure of the lower mold body 1 at the second cross section. On the second cross section, the second guide groove 113 is V-shaped, the second guide groove 113 is connected to the first receiving groove 101, and the opening of the second guide groove 113 faces the upper mold body 2, and the second guide groove 113 is also used to guide the metal wire 2001 into the first receiving groove 101, wherein the second cross section is located between one end of the third guide platform 110 and the other end of the third guide platform 110, and the second cross section is perpendicular to the extension direction of the first receiving groove 101. In this embodiment, a first guide platform 108, a second guide platform 109, a third guide platform 110 and a fourth guide platform 111 are provided, and a first guide groove 112 is formed between the first guide platform 108 and the second guide platform 109, and a second guide groove 113 is formed between the third guide platform 110 and the fourth guide platform 111. The metal wire 2001 is guided into the first receiving groove 101 through the first guide groove 112 and the second guide groove 113, so that it is convenient to place the metal wire 2001 into the first receiving groove 101, which helps to reduce the difficulty of workers placing the metal wire 2001 in the first receiving groove 101, and further helps to improve the production efficiency of the plastic product 200.

[0044] For further information, see Figure 4 and Figure 6 , Figure 4The dotted box pointed to by the middle number 1011 indicates the area of ​​the first starting section 1011, and the dotted box pointed to by the number 1013 indicates the area of ​​the first ending section 1013. The first receiving groove 101 includes the first starting section 1011, the first middle section 1012 and the first ending section 1013. One end of the first middle section 1012 is connected to one end of the first starting section 1011, the other end of the first starting section 1011 is connected to the first cavity 102, the other end of the first middle section 1012 is connected to one end of the first ending section 1013, and the other end of the first ending section 1013 is connected to the second cavity 103. The first boss 104 and the second boss 105 are both located at one end of the first middle section 1012, and the first boss 104 and the second boss 105 are located on both sides of the first middle section 1012 respectively. The third boss 106 and the fourth boss 107 are both located at the other end of the first middle section 1012, and the third boss 106 and the fourth boss 107 are respectively located at both sides of the first middle section 1012. In this embodiment, by arranging the first boss 104 and the second boss 105 at one end of the first middle section 1012, and arranging the third boss 106 and the fourth boss 107 at the other end of the first middle section 1012, it is helpful to reduce the risk of the metal wire 2001 being separated from the first receiving groove 101 as much as possible.

[0045] For further information, see Figure 6 , Fig.11 and Fig.12 The lower mold body 1 is further provided with a first glue inlet channel 116 and a second glue inlet channel 117. The first glue inlet channel 116 is connected to the first cavity 102. When the metal wire 2001 is placed in the first receiving groove 101, the metal wire 2001 abuts against the side wall of the first starting section 1011 away from the first glue inlet channel 116. When the plastic raw material is injected into the first cavity 102 from the first injection channel 116, the plastic raw material impacts a portion of the metal wire 2001 located in the first cavity 102. If there is a gap between the metal wire 2001 and the side wall of the first starting section 1011 away from the first injection channel 116, the plastic raw material is likely to impact a portion of the metal wire 2001 located in the first cavity 102, causing the metal wire 2001 to deform, which may easily lead to a defective plastic product 200. Therefore, by making the metal wire 2001 abut against the side wall of the first starting section 1011 away from the first injection channel 116, the deformation of the metal wire 2001 when the plastic raw material is injected into the first cavity 102 can be reduced, which is beneficial to improving the yield rate of the plastic product 200.

[0046] See also Figure 6 , Fig.13 and Fig.14The second glue inlet channel 117 is connected to the second cavity 103 . When the metal wire 2001 is placed in the first receiving groove 101 , the metal wire 2001 abuts against the side wall of the first tail section 1013 facing away from the second glue inlet channel 117 . When the plastic raw material is injected into the second cavity 103 from the second injection channel 117, the plastic raw material impacts a portion of the metal wire 2001 located in the second cavity 103. If there is a gap between the metal wire 2001 and the side wall of the first tail section 1013 away from the second injection channel 117, the plastic raw material is likely to impact a portion of the metal wire 2001 located in the second cavity 103, causing the metal wire 2001 to deform, which is also likely to cause a defective plastic product 200. Therefore, by making the metal wire 2001 abut against the side wall of the first tail section 1013 away from the second injection channel 117, the deformation of the metal wire 2001 when the plastic raw material is injected into the second cavity 103 can be reduced, which is beneficial to improving the yield rate of the plastic product 200.

[0047] In some embodiments, see Fig.12 and Fig.14 There may be a gap between the side wall of the first starting section 1011 close to the first glue feeding channel 116 and the metal wire 2001, which can reduce the processing accuracy of the lower mold body 1 and make it easier to place the metal wire 2001 in the first starting section 1011 of the first receiving groove 101. There may also be a gap between the side wall of the first ending section 1013 close to the second glue feeding channel 117 and the metal wire 2001, which can also make it easier to place the metal wire 2001 in the first ending section 1013. It is worth noting that the maximum size of the gap between the side wall of the first starting section 1011 and the metal wire 2001 and the gap between the side wall of the first ending section 1013 and the metal wire 2001 does not exceed 0.015 mm, which can prevent the plastic material from entering the first starting section 1011 or the first ending section 1013.

[0048] In some embodiments, see Figure 6 The lower mold body 1 is also provided with a limiting portion 118, and the limiting portion 118 is provided in the second cavity 103. The limiting portion 118 is aligned with the first tail section 1013 and connected to one end of the second cavity 103. The limiting portion 118 is used to position the metal wire 2001. When the metal wire 2001 is placed in the first receiving groove 101, the end of the metal wire 2001 needs to be abutted against the limiting portion 118, so as to achieve the positioning of the metal wire 2001.

Specifically, the surface of the first boss 104 facing the second boss 105 constitutes a part of the side wall of the first receiving groove 101, and the surface of the second boss 105 facing the first boss 104 constitutes a part of the side wall of the first receiving groove 101. It should be noted that, on the third cross section, the depth of the first receiving groove 101 is greater than the radius of the metal wire 2001 and less than the diameter of the metal wire 2001, wherein the vertical distance from the first surface 1041 of the first boss 104 to the bottom of the first receiving groove 101 is the depth of the first receiving groove 101 on the third cross section, and the first surface 1041 faces the upper mold body 2. That is, when the metal wire 2001 is placed in the first receiving groove 101, in the direction perpendicular to the first surface 1041, at least more than half of the metal wire 2001 between the first boss 104 and the second boss 105 is received in the first receiving groove 101, and at least part of the metal wire 2001 protrudes from the first surface 1041, so that the spring-pressing assembly 3 can press the part of the metal wire 2001 protruding from the first surface 1041. In this embodiment, the shape of the first receiving groove 101 in the third cross section is U-shaped, and in the third cross section, the depth of the first receiving groove 101 is greater than the radius of the metal wire 2001 and less than the diameter of the metal wire 2001, so that the metal wire 2001 is not easy to escape from the first receiving groove 101.

[0050] For further information, see Fig.17 and Fig.18 , Fig.17: is a schematic diagram of the partial cross-section structure of the mold 100 on the fourth cross section, and the shape of the first receiving groove 101 on the fourth cross section is U-shaped, wherein the fourth cross section is located at any position between one end of the third boss 106 and the other end of the third boss 106. Specifically, the surface of the third boss 106 facing the fourth boss 107 constitutes a part of the side wall of the first receiving groove 101, and the surface of the fourth boss 107 facing the third boss 106 constitutes a part of the side wall of the first receiving groove 101. It should be noted that, on the fourth cross section, the depth of the first receiving groove 101 is greater than the radius of the metal wire 2001 and less than the diameter of the metal wire 2001, wherein the vertical distance from the second surface 1061 of the third boss 106 to the bottom of the first receiving groove 101 is the depth of the first receiving groove 101 on the fourth cross section, and the second surface 1061 faces the upper mold body 2. That is, when the metal wire 2001 is placed in the first receiving groove 101, in the direction perpendicular to the second surface 1061, at least more than half of the metal wire 2001 between the third boss 106 and the fourth boss 107 is received in the first receiving groove 101, and at least part of the metal wire 2001 protrudes from the second surface 1061, so that the spring-pressing assembly 3 can press the part of the metal wire 2001 protruding from the second surface 1061. In this embodiment, the shape of the first receiving groove 101 in the fourth cross section is U-shaped, and in the fourth cross section, the depth of the first receiving groove 101 is greater than the radius of the metal wire 2001 and less than the diameter of the metal wire 2001, so that the metal wire 2001 is not easy to escape from the first receiving groove 101.

[0051] For the upper mold body 2, please refer to 6. Fig.19 and Fig. 20 The upper mold body 2 is provided with a second receiving groove 201, a third cavity 202 and a fourth cavity 203. One end of the second receiving groove 201 is connected to the third cavity 202, and the other end of the second receiving groove 201 is connected to the fourth cavity 203.
