Description

Technical Field

[0001] This invention relates to the field of speaker bracket processing technology, specifically to a processing and forming device and method for a mobile phone speaker bracket. Background Technology

[0002] A mobile phone speaker is an electronic component inside a mobile phone used for sound output; it is a type of sound-generating unit. It converts electrical signals into sound waves through electromagnetic conversion and is mainly used for functions such as calls and music playback. It is usually integrated around the mobile phone's motherboard.

[0003] Over 90% of these components employ a dynamic coil design, using magnets and electromagnetic coils to drive the diaphragm to vibrate and produce sound. Other types include electromagnetic and planar types. The core structure consists of a diaphragm, electromagnetic coil, and magnets. The diaphragm is often made of MCPET material and equipped with a dustproof pad. In practical applications, it is necessary to maintain a symmetrical layout of the left and right speakers to avoid stereo distortion caused by distance differences, while also minimizing resonance interference around the components. Planar designs use a honeycomb diaphragm structure to reduce sound coloration and improve sound clarity. When the phone is tilted, the change in the distance between the speaker and the ear affects the sound field effect; placing speakers on both sides makes it easier to create distance differences.

[0004] Traditional mobile phone speakers cannot be fitted into the phone on their own; a matching bracket is required for them to be successfully installed on the motherboard. However, manual installation is difficult to align and prone to misalignment, resulting in significant manufacturing errors in the speaker bracket. Furthermore, the conventional processing of mobile phone speaker brackets is relatively simple and complex, which is not conducive to the positioning, extrusion, and fitting of the speaker. This adds many steps and wastes time on the speaker bracket. Moreover, demolding after molding is also very important. It is necessary to automate the demolding of the finished speaker bracket to achieve industrialized and streamlined production. Summary of the Invention

[0005] The purpose of this invention is to provide a processing and forming device and method for a mobile phone speaker bracket, which solves the problem mentioned in the background art that traditional mobile phone speakers cannot be adapted to the mobile phone on their own and require a corresponding bracket to be successfully installed in the mobile phone motherboard.

[0012] A method for processing and forming a mobile phone speaker holder, comprising the processing and forming apparatus for a mobile phone speaker holder as described in claim 1: S1: Material injection for the mobile phone speaker; S2: The assembly of the upper and lower molds; S3: Demolding.

[0013] As a preferred embodiment of the present invention: S1 is specifically as follows: At this time, the I-shaped bracket is used to share the weight of the mold placement, the upper configuration box completes the force support for the conical cover, and the damping roller shaft set on one side of the linear access seat is used to achieve tight closing of the two molds. The hinge part is based on the bearing upright and the upper movable joint. Due to the extension and retraction length of the pneumatic cylinder, the two molds are unfolded. When closing is required, only the upper movable joint needs to be shortened. Based on the support of the upper frame and the transverse support of the connecting crossbar, the upper and lower molds are compacted to avoid gaps at the mold joint.

[0014] As a preferred embodiment of the present invention: S2 specifically involves shaping the speaker portion of the microphone by using the groove between the shaping groove and one end of the assembly base to achieve vertical flipping and closure, forming a cavity. The cavity has a space for shaping. The contact edges of the two molds are pulled by a hinge shaft. The hinged arc-shaped pad flips and, combined with the insertion cavity grooves opened at the four corners of the lower injection mold, serves as the four-sided positioning points when the mold is closed, preventing the upper and lower molds from not corresponding. With the help of the hinge bracket, the surface of the sliding extension of the first linear track slides up and down, changing the support height of the hinge bracket. When the hinge bracket is laid flat, the two molds are completely closed. After the surface of the molding cavity and the speaker cavity groove are closed and formed into a complete cavity, subsequent injection molding operations can be performed.

[0015] As a preferred embodiment of the present invention: S3 specifically involves: sliding linearly up and down along one end of the corresponding second linear track, using a sliding base for displacement, ensuring that the upper and lower molds can be opened with the help of a drive roller, lifting up and down and turning left and right according to the arc-shaped bracket, pressing down and compacting after magnetic adsorption through the connecting base to prevent rebound, and tightly locking; liquid insertion, using a conical conduit for pipe passage, using the pipe passage of the injection tube to facilitate injection of the plastic for the mobile phone speaker bracket to be shaped, supported by the tube body of the arc-shaped sleeve, and to ensure that the position of the injection tube body is fixed, using the surface of the upper half of the cap to achieve a tight seal, using the support structure corresponding to the bottom of the arc-shaped sleeve for support, using the corresponding second linear track for fitting, using a specific connecting rod for support, using a connecting bracket to achieve forward and backward sliding, using a stepper motor for powering, the motor will move forward and backward around the linear sliding track, the position of the seat push rods will achieve forward and backward movement, using the surface movement of the linear sliding track to gradually push the shaped speaker device directly into the groove, facilitating the unfolding of the molds on both sides, so that after shaping, the molds on both sides can be opened to complete the removal. Compared with the prior art, the beneficial effects of the present invention are: 1) By using an I-shaped bracket and an adapter box, the assembly of the speaker bracket injection molding part is achieved. Combined with the liquid extraction base, the melted plastic liquid is injected into the molding mold. The overflow part is discharged through the L-shaped drain pipe. The upper half of the cover is used to complete the splicing and combination of the molding cavity between the upper and lower molding molds. After the upper and lower molds are closed, the plastic liquid is injected into the molding cavity for batch cooling, thus realizing the function of mass production of mobile phone speaker brackets. 2) The connecting bracket and the access base are used. The operator slides the upper mold along the upper mold to achieve the splicing and sealing combination of the two molds. The upper and lower molds are fastened together by the access base and the limit screws to complete the limiting of the two molds. When the mobile phone speaker bracket inside the mold is injection molded, the damping roller is used to flip it back and forth to complete the unfolding of the upper and lower molds and automatic demolding. The operator can then take out the molded mobile phone speaker bracket. The power source for mold traction is the extension and retraction of the cylinder of the pneumatic pressure cylinder, which drives the height change of the upper movable joint to complete the automated demolding. The connecting crossbar is used to lift the upper and lower molds to realize the process of opening and closing the upper and lower molds, avoiding manual operation. The automated demolding and the opening of the assembly base realize the demolding of the finished mobile phone speaker bracket, improving the processing efficiency of the speaker bracket and reducing the consumption of manpower and material resources. 3) The stepper motor drives the gear to rotate after being powered on. The gear meshing displacement is achieved by using the surface of the linear sliding track, which changes the forward and backward movement of the push rod, ensuring that the finished mobile phone speaker bracket can be demolded and removed. The sliding base and arc bracket are used for support, which shares the supporting weight of the upper mold. Attached Figure Description

After the molten plastic cools, it matches the shape of the cavity and can be directly demolded to complete the processing of the mobile phone speaker.

[0025] In this embodiment: a plurality of horn cavity grooves 492 for horn shaping are arranged sequentially on the surface of the adjusting roller 49. An assembly base 493 is provided on the surface of the horn cavity groove 492. A hinge roller 494 is provided at the middle of the bottom end of the hinge bracket 47.

When closing is required, only the upper movable joint (38) needs to be shortened. Based on the support of the upper frame (39), the horizontal support of the connecting crossbar (391) completes the compaction of the upper and lower molds to avoid gaps at the mold joint.

9. The processing and forming method of a mobile phone speaker bracket according to claim 7, characterized in that: S2 specifically refers to: shaping the speaker part of the microphone, using the groove between the shaping groove (44) and one end of the assembly base (493) to achieve up-and-down flipping and closing to form a cavity, forming a space inside the cavity for shaping, the contact edge of the two molds is pulled by the hinge shaft (45), the hinge upper arc-shaped pad (46) flips, combined with the insertion cavity groove (42) opened at the four corners of the lower injection mold (41) as the four-sided positioning points when the mold is closed, to avoid the upper and lower molds not being able to correspond, with the help of the hinge bracket (47), the surface of the sliding extension of the first linear track (48) slides up and down the track, changing the support height of the hinge bracket (47), when the hinge bracket (47) is laid flat, the two molds are completely closed, the surface of the molding cavity (491) and the speaker cavity groove (492) are closed and formed into a whole part to form a complete cavity, and then the subsequent injection molding operation can be carried out.

10. The processing and forming method of a mobile phone speaker bracket according to claim 7, characterized in that: S3 specifically involves: sliding vertically up and down along one end of the corresponding second linear track (61), using the sliding base (62) for displacement, ensuring the upper and lower molds can be opened with the help of the drive roller (63), achieving vertical lifting and horizontal deflection according to the arc-shaped bracket (64), pressing down to prevent rebound after magnetic adsorption through the connecting base (66), tightly clamping, liquid insertion, using the conical conduit (56) for pipe passage, using the pipe passage of the injection tube (55) to conveniently inject the plastic of the mobile phone speaker bracket to be formed, supported by the tube body of the arc-shaped sleeve (57), in order to ensure the fixed position of the tube body of the injection tube (55), using the upper half of the cap ( 58) achieves a tight seal on the surface, supports the bottom of the arc sleeve (57) according to the support structure, and is connected according to the corresponding second linear track (61). It is supported by the specific connecting rod (54), and slides back and forth using the connecting bracket (51). When the stepper motor (24) is powered on, the motor will move back and forth around the linear sliding track (22). The position of the seat push rod (25) moves back and forth. By moving the surface of the linear sliding track (22), the shaped horn device is gradually pushed directly into the slot, which facilitates the unfolding of the molds on both sides. After the shaping is completed, the molds on both sides are opened to complete the demolding.
