Description

Technical Field

[0001] This invention relates to the field of mold technology, and in particular to a method for preparing a post-attachment component. Background Technology

[0002] Bone conduction headphones generally include a back hook, a left ear hook, and a right ear hook. The two ends of the back hook are connected to the left ear hook and the right ear hook, respectively. The back hook generally includes a metal strip and a silicone layer for wrapping the metal strip. The metal strip is used to give the back hook a specific shape.

[0003] Currently, molds used for producing aftermarket parts generally include a first mold body and a second mold body. The first mold body has a first cavity, and the second mold body has a second cavity. When the first mold body and the second mold body are closed, the first cavity and the second cavity together form the product cavity. Before the first mold body and the second mold body are closed, the raw material is first laid in the first cavity and the second cavity, and then the metal strip is placed in the first cavity or the second cavity. Then the first mold body and the second mold body are closed, and then pressure is applied to the first mold body and the pressure is maintained for a period of time, so that the raw material in the product cavity undergoes a vulcanization reaction, thereby forming the aftermarket part.

[0004] During the implementation of this invention, the inventors discovered that when using the above-mentioned mold to produce the back hanger, the metal strip in the back hanger is easily exposed, resulting in poor appearance of the back hanger. Summary of the Invention

[0005] The main technical problem solved by the embodiments of the present invention is to provide a mold, a method for preparing a post-attachment, and a post-attachment, which can overcome the above problems or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, one technical solution adopted in this embodiment of the invention is as follows: A mold is provided, comprising a first mold body, a second mold body, a pre-formed mold body, and an installation module. The first mold body has a first cavity; the second mold body has a second cavity; the pre-formed mold body has a first forming part and a second forming part, the first forming part being disposed on a first surface of the pre-formed mold body, and the second forming part being disposed on a second surface of the pre-formed mold body, with the first and second surfaces facing each other. When the pre-formed mold body is positioned between the first and second mold bodies, the first forming part and the first cavity together form a first half-cavity, and the second forming part and the second cavity together form a second half-cavity. The first half-cavity is used to form a first part of the post-attachment, and the second half-cavity is used to form a second part of the post-attachment. The installation module is used to install a metal strip. When the first and second mold bodies are closed and the installation module is placed between the first and second mold bodies, the first and second cavities together form a finished product cavity, through which the metal strip passes, so that the first and second parts together cover the metal strip to form the post-attachment.

[0007] Optionally, the first mold body is further provided with a first overflow groove and a first connecting port, the first overflow groove surrounding the first cavity, and the first connecting port connecting the first cavity and the first overflow groove.

[0008] Optionally, the first mold body is further provided with a second overflow groove and a second connecting port. The first overflow groove, the first cavity and the second overflow groove are arranged at intervals, and the first cavity is located between the first overflow groove and the second overflow groove. The second connecting port connects the first cavity and the second overflow groove.

[0009] Optionally, the second mold body is provided with a third overflow groove and a third connecting port, the third overflow groove surrounds the second cavity, and the third connecting port connects the second cavity and the third overflow groove.

[0010] Optionally, the second mold body is further provided with a fourth overflow groove and a fourth connecting port. The third overflow groove, the second cavity and the fourth overflow groove are arranged at intervals, and the second cavity is located between the third overflow groove and the fourth overflow groove. The fourth connecting port connects the second cavity and the fourth overflow groove.

[0011] To solve the above-mentioned technical problems, another technical solution adopted in this embodiment of the invention is: providing a method for preparing a post-attachment, the method comprising:

[0012] Provide the first raw material, the second raw material, and the aforementioned mold;

[0013] Heat the first and second molds;

[0014] The first raw material is laid in the first cavity;

[0015] The second raw material is laid on the second molding section;

[0016] The preformed mold is placed on the first mold, and the first forming part is received in the first cavity to form the first half cavity;

[0017] The second mold body is stacked on the surface of the preformed mold body away from the first mold body, and the second molding part is received in the second cavity to form the second half cavity;

[0018] A pressure is applied to the second mold body in the direction toward the first mold body, so that the first raw material fills the first half cavity to form the first part of the rear hanger, and the second raw material fills the second half cavity to form the second part of the rear hanger;

[0019] Remove the preformed mold body;

[0020] A metal strip is provided, and the metal strip is installed on the mounting module;

[0021] The mounting module with the metal strip installed is installed on the first mold body, and the metal strip passes through the first cavity of the first mold body;

[0022] The second mold and the first mold are then joined together.

[0023] Pressure is applied to the first mold and the second mold and held for a predetermined time so that both the first part and the second part of the rear hanger undergo a vulcanization reaction, thereby forming the rear hanger together with the first part, the second part and the metal strip.

[0024] Remove the rear attachment from the mold.

[0025] Optionally, before the step of joining the second mold and the first mold, the method further includes:

[0026] Provide wires;

[0027] The wire is bonded to the metal strip.

[0028] Optionally, before the step of joining the second mold and the first mold, the method further includes:

[0029] Apply adhesive to the surfaces of the wires and metal strips.

[0030] Optionally, after the step of removing the rear hanger from the mold, the method further includes:

[0031] Check the rear hanger for any residual adhesive;

[0032] If present, clean off any remaining adhesive.

[0033] To solve the above-mentioned technical problems, another technical solution adopted in this embodiment of the invention is to provide a rear hanger, which is prepared by the above-described method.

[0034] The beneficial effects of this invention are as follows: Unlike the prior art, this invention pre-forms the first part and the second part of the hanger using a pre-formed mold, then removes the pre-formed mold, and places the mounting module with the metal strip between the first mold and the second mold, allowing the metal strip to pass through the finished product cavity formed by the first mold and the second mold. This allows the first part and the second part to jointly cover the metal strip to form the hanger, which helps reduce the risk of metal strip exposure and the risk of poor appearance of the hanger.

[0057] Figure 1 and Figure 2 This is a schematic diagram of the structure of a rear hanger 200 produced using the mold 100 embodiment of the present invention. The rear hanger 200 includes a first part 2001, a second part 2002, a metal strip 2003, and a wire 2004. The metal strip 2003 and the wire 2004 are bonded and fixed together. The length of the wire 2004 is greater than the length of the first part 2001, and both ends of the wire 2004 protrude from the first part 2001 to facilitate connection between the wire 2004 and other components. The first part 2001 and the second part 2002 together wrap the metal strip 2003 and the wire 2004. One end of the metal strip 2003 is provided with a first protrusion 20031, and the other end of the metal strip 2003 is provided with a second protrusion 20032. The first protrusion 20031 and the second protrusion 20032 are used to prevent the metal strip 2003 from slipping out of the first part 2001 and the second part 2002.

[0058] Please see Figures 1 to 14The mold 100 includes: a first mold body 1, a second mold body 2, a pre-formed mold body 3, and an installation module 4. When the pre-formed mold body 3 is disposed between the first mold body 1 and the second mold body 2, the pre-formed mold body 3 is used to cooperate with the first mold body 1 to form the first part 2001 and to cooperate with the second mold body 2 to form the second part 2002. The installation module 4 is used to install the metal strip 2003 so that when the first mold body 1 and the second mold body 2 are closed, the metal strip 2003 can be positioned between the first part 2001 and the second part 2002.

[0059] The first mold body 1 described above is provided with a first cavity 11, a first overflow trough 12, a second overflow trough 13, a first connecting port 14, and a second connecting port 15. The first overflow trough 12 surrounds the first cavity 11, and the first overflow trough 12, the first cavity 11, and the second overflow trough 13 are spaced apart, with the first cavity 11 located between the first overflow trough 12 and the second overflow trough 13. The first connecting port 14 connects the first cavity 11 and the first overflow trough 12, and the second connecting port 15 connects the first cavity 11 and the second overflow trough 13. Both the first overflow trough 12 and the second overflow trough 13 are used to collect raw materials overflowing from the first cavity 11.

[0060] The second mold body 2 described above is provided with a second cavity 21, a third overflow trough 22, a fourth overflow trough 23, a third connecting port 24, and a fourth connecting port 25. The third overflow trough 22 surrounds the second cavity 21, and the third overflow trough 22, the second cavity 21, and the fourth overflow trough 23 are spaced apart, with the second cavity 21 located between the third overflow trough 22 and the fourth overflow trough 23. The third connecting port 24 connects the second cavity 21 and the third overflow trough 22, and the fourth connecting port 25 connects the second cavity 21 and the fourth overflow trough 23. Both the third overflow trough 22 and the fourth overflow trough 23 are used to collect raw materials overflowing from the second cavity 21.

[0061] The preformed mold 3 described above is provided with a first forming part 31 and a second forming part 32. The first forming part 31 is disposed on the first surface of the preformed mold 3, and the second forming part 32 is disposed on the second surface of the preformed mold 3, with the first surface and the second surface facing each other. When the preformed mold 3 is placed between the first mold 1 and the second mold 2, the first mold 1 abuts against the first surface, and the first forming part 31 is received in the first cavity 11, so that the first forming part 31 and the first cavity 11 together form a first half-cavity 5, which is used to form the first part 2001 of the rear hanger 200. At the same time, the second mold 2 abuts against the second surface, and the second forming part 32 is received in the second cavity 21, so that the second forming part 32 and the second cavity 21 together form a second half-cavity 6, which is used to form the second part 2002 of the rear hanger 200.

[0062] In some embodiments, both the first molding portion 31 and the second molding portion 32 are coated with an anti-stick coating (not shown). When the first mold body 1, the pre-molded mold body 3, and the second mold body 2 are used to jointly mold the first part 2001 and the second part 2002, and the pre-molded mold body 3 is removed, the adhesion between the first part 2001 and the inner wall of the first cavity 11 is greater than the adhesion between the first part 2001 and the first molding portion 31. Therefore, the first part 2001 remains in the first cavity 11, and the adhesion between the second part 2002 and the inner wall of the second cavity 21 is greater than that between the first part 2001 and the first molding portion 31. The second part 2002 adheres well to the second molding part 32, so the second part 2002 remains in the second cavity 21; then the mounting module 4, which is equipped with a metal strip 2003 and a wire 2004, is installed on the first mold body 1, and the wire 2004 and the metal strip 2003 pass through the first part 2001 of the first cavity 11. Then the second mold body 2 and the first mold body 1 are closed, so that the first part 2001 and the second part 2002 together wrap the metal strip 2003 and partially wrap the wire 2004, finally forming the rear hanger 200.

[0063] In some embodiments, the anti-stick coating is made of Teflon.

[0064] In some embodiments, the mold 100 further includes a plurality of first positioning rods 7, all of which are fixed to the first mold body 1, and all of which protrude from the surface of the first mold body 1 where the first cavity 11 is provided. The preformed mold body 3 is provided with a plurality of first positioning grooves 33, and the second mold body 2 is also provided with a plurality of second positioning grooves 26. When the preformed mold body 3 is placed between the first mold body 1 and the second mold body 2, the portion of one of the first positioning rods 7 protruding from the first mold body 1 passes through a first positioning groove 33 and is inserted into a second positioning groove 26, thereby achieving positioning between the preformed mold body 3, the first mold body 1 and the second mold body 2, so that the first forming part 31 can be received in the first cavity 11 to form the first half cavity 5, and the second forming part 32 can be received in the second cavity 21 to form the second half cavity 6.

[0065] The installation module 4 described above includes an installation component 41, a first mounting member 42, a second mounting member 43, a third mounting member 44, and a fourth mounting member 45. The first mounting member 42, the second mounting member 43, the third mounting member 44, and the fourth mounting member 45 are all mounted on the installation component 41. The first mounting member 42 and the second mounting member 43 are used together to mount the first protrusion 20031 of the metal strip 2003, and the third mounting member 44 and the fourth mounting member 45 are used together to mount the second protrusion 20032 of the metal strip 2003, thereby fixing the metal strip 2003 to the installation module 4.

[0066] The mounting assembly 41 described above includes a first mounting base 412 and a second mounting base 413. The first mounting base 412 has a first mounting groove 4121 and a third mounting groove 4122 on its surface facing the second mounting base 413. One end of the first mounting member 42 is received in the first mounting groove 4121, and the first mounting member 42 is fixed to the first mounting base 412 by a first screw connector 414. One end of the third mounting member 44 is received in the third mounting groove 4122, and the third mounting member 44 is fixed to the second mounting base 413 by a second screw connector 415. The second mounting base 413 has a second mounting groove 4131 and a fourth mounting groove 4132 on its surface facing the first mounting base 412, and the second mounting groove 4131 communicates with the first mounting groove 4121, and the third mounting groove 4122 communicates with the fourth mounting groove 4132. One end of the second mounting member 43 is received in the second mounting groove 4131, and the second mounting member 43 is fixed to the second mounting base 413 by a third screw connector 416. One end of the fourth mounting member 45 is received in the fourth mounting groove 4132, and the fourth mounting member 45 is fixed to the fourth mounting base by a fourth screw connector 417. The first mounting base 412 and the second mounting base 413 are fixed together by a plurality of fifth screw connectors 418. The surface of the first mounting member 42 facing the third mounting member 44 is provided with a first receiving groove 421 and a first through groove 422; the surface of the second mounting member 43 facing the fourth mounting member 45 is provided with a second receiving groove 431 and a second through groove 432; the surface of the third mounting member 44 facing the first mounting member 42 is provided with a third receiving groove 441 and a third through groove 442; and the surface of the fourth mounting member 45 facing the second mounting member 43 is provided with a fourth receiving groove 451 and a fourth through groove 452. Before placing the mounting module 4 between the first mold 1 and the second mold 2, the metal strip 2003 needs to be installed on the mounting module 4. The specific steps are as follows:

[0067] One end of the first mounting component 42 is fixed to the first mounting groove 4121;

[0068] One end of the second mounting component 43 is fixed to the second mounting groove 4131;

[0069] One end of the third mounting member 44 is fixed to the third mounting groove 4122;

[0070] One end of the fourth mounting component 45 is fixed to the fourth mounting groove 4132;

[0071] The first protrusion 20031 of the metal strip 2003 is placed in the first receiving groove 421, and one end of the wire 2004 is placed in the first through groove 422. At this time, the first protrusion 20031 protrudes out of the first receiving groove 421, and one end of the wire 2004 protrudes out of the first through groove 422.

[0072] The second protrusion 20032 of the metal strip 2003 is placed in the third receiving groove 441, and the other end of the wire 2004 is placed in the third through groove 442. At this time, the second protrusion 20032 protrudes out of the third receiving groove 441, and the other end of the wire 2004 protrudes out of the third through groove 442.

[0073] The second mounting base 413 is fixed to the first mounting base 412 by the fifth screw connector 418. At this time, the second receiving groove 431 receives the portion of the first protrusion 20031 that protrudes from the first receiving groove 421, the second through groove 432 receives the portion of one end of the wire 2004 that protrudes from the first through groove 422, the fourth receiving groove 451 receives the portion of the second protrusion 20032 that protrudes from the third receiving groove 441, and the fourth through groove 452 receives the portion of the other end of the wire 2004 that protrudes from the third through groove 442. Thus, the first mounting member 42 and the second mounting member 43 jointly fix the first protrusion 20031, and the third mounting member 44 and the fourth mounting member 45 jointly fix the second protrusion 20032.

[0074] In some embodiments, the mold 100 further includes a plurality of second positioning rods 8, one end of each of the plurality of second positioning rods 8 being fixed to the first mold body 1, and the other end of each of the plurality of second positioning rods 8 protruding from the surface of the first mold body 1 facing the second mold body 2, and the plurality of second positioning rods 8 being spaced apart. The mounting assembly 41 is also provided with a plurality of third positioning grooves 411, the plurality of third positioning grooves 411 passing through the first mounting base 412 and the second mounting base 413. When the mounting module 4 is placed between the first mold body 1 and the second mold body 2, the portion of a second positioning rod 8 protruding from the first mold body 1 is inserted into a third positioning groove 411, thereby allowing the metal strip 2003 and the wire 2004 mounted on the mounting module 4 to pass through the finished product cavity 9 formed by the first cavity 11 and the second cavity 21. It is understood that the preformed mold body 3 is also provided with a plurality of fourth positioning grooves 34, which are spaced apart. When the preformed mold body 3 is used to preform the first part 2001 and the second part 2002, a portion of the second positioning rod 8 protruding from the first mold body 1 is inserted into a fourth positioning groove 34. This not only positions the preformed mold body 3 but also avoids interference between the preformed mold body 3 and the second positioning rod 8.

[0075] In this embodiment of the invention, the first part 2001 and the second part 2002 of the rear hanger 200 are pre-formed by the pre-formed mold 3. Then, the pre-formed mold 3 is removed, and the installation module 4 with the metal strip 2003 is placed between the first mold 1 and the second mold 2. The metal strip 2003 passes through the finished cavity 9 formed by the first mold 1 and the second mold 2. Thus, the first part 2001 and the second part 2002 together cover the metal strip 2003 to form the rear hanger 200, which helps to reduce the risk of the metal strip 2003 being exposed and the risk of the rear hanger 200 having poor appearance.

[0076] The present invention provides another embodiment of a method for preparing a rear pendant 200, wherein the method is applied to the mold 100 described above.

[0077] Example 1

[0078] Please see Figures 1 to 15 The method for preparing the post-attachment 200 includes:

[0079] Step 01: Provide the first raw material, the second raw material, and the aforementioned mold 100;

[0080] The first and second raw materials are made of the same material and are both in a soft, viscous colloidal form. The main components of both raw materials are a mixture of silicone rubber, high-strength heat-cured silicone rubber, a vulcanizing agent, and a vulcanization inhibitor. The vulcanizing agent catalyzes the vulcanization of the first and second raw materials, causing them to harden and bond together. The catalytic effect of the vulcanizing agent is stronger under heating and increased pressure conditions than under normal temperature and pressure conditions. The vulcanization inhibitor can inhibit the vulcanization of the first and second raw materials at room temperature, but it rapidly degrades under heating conditions.

[0081] Step 02: Heat the first mold 1 and the second mold 2;

[0082] The first mold 1 and the second mold 2 can be heated to above 100 degrees Celsius and maintained at that temperature.

[0083] Step 03: Lay the first raw material into the first cavity 11;

[0084] Step 04: Lay the second raw material onto the second forming part 32;

[0085] Step 05: Place the preformed mold 3 on the first mold 1, and make the first forming part 31 accommodate the first cavity 11 to form the first half cavity 5;

[0086] The first raw material fills the first half-cavity 5.

[0087] Step 06: The second mold body 2 is stacked on the surface of the preformed mold body 3 away from the first mold body 1, and the second forming part 32 is received in the second cavity 21 to form the second half cavity 6;

[0088] The second raw material fills the second half-cavity 6.

[0089] Step 07: Apply pressure to the second mold 2 in the direction of the first mold 1 so that the first raw material fills the first half cavity 5 to form the first part 2001 of the rear hanger 200, and the second raw material fills the second half cavity 6 to form the second part 2002 of the rear hanger 200.

[0090] Excess first raw material is collected in the first overflow trough 12 through the first connecting port 14, and excess first raw material is collected in the second overflow trough 13 through the second connecting port 15. Excess second raw material is collected in the third overflow trough 22 through the third connecting port 24, and excess second raw material is collected in the fourth overflow trough 23 through the fourth connecting port 25. It is worth noting that the pressure applied to the second mold 2 in the direction of the first mold 1 is not more than 5 seconds to prevent the first raw material in the first half-cavity 5 and the second raw material in the second half-cavity 6 from vulcanizing.

[0091] Step 08: Remove the preformed mold 3;

[0092] Since the first forming part 31 and the second forming part 32 of the preformed mold body 3 are both coated with an anti-stick coating, when the preformed mold body 3 is removed, the first part 2001 remains directly in the first cavity 11, and the second part 2002 remains directly in the second cavity 21.

[0093] Step 09: Provide metal strip 2003 and install the metal strip 2003 onto the mounting module 4;

[0094] The first mounting component 42 and the second mounting component 43 of the mounting module 4 together fix the first protrusion 20031 of the metal strip 2003, and the third mounting component 44 and the fourth mounting component 45 of the mounting module 4 together fix the second protrusion 20032 of the metal strip 2003.

[0095] Step 10: Install the mounting module 4, on which the metal strip 2003 is installed, onto the first mold body 1, such that the metal strip 2003 passes through the first cavity 11 of the first mold body 1;

[0096] Step 11: Close the second mold 2 and the first mold 1 together. At this time, the positional relationship between the first mold 1, the second mold 2 and the mounting module 4 is as follows: Figure 7 As shown;

[0097] Step 12: Apply pressure to the first mold 1 and the second mold 2 and hold for a predetermined time so that the first part 2001 and the second part 2002 of the rear hanger 200 both undergo vulcanization reaction, so that the first part 2001, the second part 2002 and the metal strip 2003 together form the rear hanger 200.

[0098] The predetermined time is no less than 90 seconds, so that the first part 2001 and the second part 2002 have sufficient time to vulcanize and form a single unit.

[0099] Step 13: Remove the rear hanger 200 from the mold 100.

[0100] In this embodiment of the invention, a pre-formed mold 3 is used to pre-form the first part 2001 and the second part 2002 of the rear hanger 200. Then, the pre-formed mold 3 is removed, and the mounting module 4 with the metal strip 2003 is installed on the first mold 1, so that the metal strip 2003 passes through the first cavity 11. Then, the first mold 1 and the second mold 2 are closed, so that the first part 2001 and the second part 2002 together wrap the metal strip 2003. Then, pressure is applied to the first mold 1 and the second mold 2 to vulcanize the first part 2001 and the second part 2002, thereby forming the rear hanger 200. This helps to reduce the risk of the metal strip 2003 being exposed when molding the rear hanger 200 and reduces the appearance defects of the rear hanger 200.

[0101] Example 2:

[0102] Please see Figures 1 to 15 The difference between Example 2 and the above examples is as follows:

[0103] After step 09 and before step 11, the method further includes:

[0104] Step 14: Provide wire 2004;

[0105] Step 15: Bond the wire 2004 to the metal strip 2003.

[0106] By bonding the wire 2004 to the metal strip 2003, after the rear hanger 200 is formed, the wire 2004 passes through the first part 2001 and the second part 2002 so that other components installed at one end of the rear hanger 200 can be electrically connected to other components installed at the other end of the rear hanger 200 through the wire 2004.

[0107] Example 3

[0108] Please see Figures 1 to 15 The difference between Example 3 and the above examples is as follows:

[0109] After step 15 and before step 11, the method further includes:

[0110] Step 16: Apply adhesive to the surfaces of the wire 2004 and the metal strip 2003.

[0111] By applying adhesive to the surfaces of the wire 2004 and the metal strip 2003, the risk of the wire 2004 separating from the metal strip 2003 during step 11 or step 12 can be reduced. At the same time, the stability of the fixation between the wire 2004 and the metal strip 2003 can be increased, making the wire 2004 less likely to detach.

[0112] Example 4

[0113] Please see Figures 1 to 15 The difference between Example 4 and the above examples is as follows:

[0114] After step 13, the method further includes:

[0115] Step 17: Check whether there is any residual adhesive on the rear hanger 200;

[0116] If so, proceed to step 18: clean up any remaining adhesive.

[0117] The aesthetics of the rear hanger 200 can be improved by cleaning off any residual adhesive.

[0118] Example 5

[0119] Please see Figures 1 to 16 The difference between Embodiment 5 and the other embodiments is as follows:

[0120] Step 08: Remove the preformed mold 3, further including...

[0121] Step 081: Remove the second mold 2 to separate the second mold 2 from the preformed mold 3;

[0122] At this time, the second part 2002 separates from the preformed mold 3 along with the second mold 2.

[0123] Step 082: Separate the preformed mold 3 from the first mold 1;

[0124] At this time, the first part 2001 remains inside the first mold 1.

[0125] Example 6

[0126] Please see Figures 1 to 17 The difference between Embodiment Six and the other embodiments is that:

[0127] Step 13: Remove the rear hanger 200 from the mold 100, further including,

[0128] Step 131: Remove the second mold 2 to separate the second mold 2 from the first mold 1;

[0129] Step 132: Remove the installation module 4 from the first mold body 1, thereby separating the rear hanger 200 from the first mold body 1;

[0130] At this time, the positional relationship of the first module 1, the second module 2, the mounting module 3, and the rear hanger 200 is as follows: Figure 18 As shown.

[0131] Step 133: Remove the second mounting base 413 from the first mounting base 412;

[0132] Since the first mounting member 42 and the third mounting member 44 are both fixed to the first mounting base 412, and the second mounting member 43 and the fourth mounting member 45 are both fixed to the second mounting base 413, when the second mounting base 413 is removed from the first mounting base 412, the first mounting member 42 and the second mounting member 43 separate, thereby releasing the fixation on the first protrusion 20031 of the metal strip 2003. At the same time, the third mounting member 44 and the fourth mounting member 45 separate, thereby releasing the fixation on the second protrusion 20032 of the metal strip 2003.

[0133] Step 134: Remove the rear mount 200 from the first mounting base 412.

[0134] In this embodiment of the invention, the first part 2001 and the second part 2002 of the rear hanger 200 are pre-formed by the pre-formed mold 3. Then, the pre-formed mold 3 is removed, and the installation module 4 with the metal strip 2003 is placed between the first mold 1 and the second mold 2. The metal strip 2003 passes through the finished cavity 9 formed by the first mold 1 and the second mold 2. Thus, the first part 2001 and the second part 2002 together cover the metal strip 2003 to form the rear hanger 200, which helps to reduce the risk of the metal strip 2003 being exposed and the risk of the rear hanger 200 having poor appearance.
