Description
Technical Field
[0001] This utility model relates to the field of processing mold technology, and in particular to a processing mold for audio speakers. Background Technology
[0002] A loudspeaker is an electroacoustic transducer that converts electrical signals into sound waves. It is widely used in various electronic devices. Its core function is to drive the diaphragm to vibrate through electromagnetic induction, thereby generating sound by pushing air. When manufacturing loudspeakers, molds are needed for the plastic shell and the speaker bracket. Currently, there are some technical challenges in demolding loudspeaker molds.
[0003] Patent document CN221819254U discloses a speaker processing mold, including a housing and a fixed plate installed at the bottom of the housing. The housing has a storage groove, in which a micro-booster is fixedly installed. The output end of the micro-booster is fixedly connected to a sealing chamber, and a sealing plug is slidably installed in the sealing chamber. A support rod is fixedly connected to the sealing plug, and the other end of the support rod extends out of the sealing chamber and is fixedly connected to a top plate. By installing the micro-booster, sealing chamber, and top plate, it is easy to quickly demold the speaker in the speaker processing mold. The micro-booster drives the air pressure in the sealing chamber to increase, pushing the sealing plug upward. The sealing plug pushes the top plate to move, so that the rubber plate contacts the sealing bottom plate and lifts the sealing bottom plate. By using the boosted pressure as the driving force to push the sealing bottom plate, the formed speaker is ejected. This design is not only simple in structure but also allows for rapid demolding, thus accelerating the processing efficiency of the speaker processing mold. However, in actual use, the booster needs to be started every time demolding is performed, resulting in high energy consumption and strong equipment dependence. Summary of the Invention
[0004] The purpose of this utility model is to provide a speaker processing mold in order to solve the above-mentioned problems.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a speaker processing mold, comprising a base and a lower mold disposed on the top of the base, wherein both ends of the top of the base are provided with insert rods extending out of the top of the lower mold, and a bottom plate located inside the lower mold is disposed at the middle of the top of the base, and a connecting mechanism is disposed inside the base, the connecting mechanism comprising a connecting rod connected to the insert rods, a spring sleeved on the outer side of the insert rods and fitting against the top of the connecting rods and the bottom of the lower mold, and an adjusting component connected to the bottom plate is disposed at the middle of the top of the connecting rods.
[0006] Preferably, a threaded block is installed at the bottom of the insertion rod, and a threaded groove adapted to the size of the threaded block is opened at the top of the connecting rod.
[0007] Preferably, both ends of the connecting rod are equipped with sliders, and the top of the base is provided with a groove that matches the size of the connecting rod and the sliders.
[0008] Preferably, the adjustment assembly includes an outer cylinder, an inner cylinder, and a motor. The outer cylinder is detachably mounted on the top of the connecting rod. An inner cylinder with its top fitting against the bottom of the base plate is fitted inside the outer cylinder. A cavity is opened on one side of the connecting rod, and a motor is placed in the cavity. The output end of the motor is connected to a threaded rod, which is threadedly connected to the inner wall of the inner cylinder.
[0009] Preferably, a sleeve fitted onto the top of the inner cylinder is installed at the bottom of the base plate, a guide block is installed at the upper end of the inner cylinder, and a lightning bolt-shaped guide groove is opened at the bottom of the sleeve to correspond with the guide block.
[0010] Preferably, the top of the base is provided with an installation groove that communicates with the slide, and the bottom of the base plate is provided with multiple grooves in an array.
[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: In this application, the insert rod is squeezed by the upper mold during use. The spring rebound force and the connecting mechanism realize the up-and-down reciprocating movement of the insert rod and the base plate, realizing automatic ejection and demolding. There is no need to start the external power source for each demolding, which is energy-saving and efficient. By setting the adjustment component, the ejection height of the base plate can be precisely adjusted according to the mold thickness, adapting to the processing needs of different specifications of products and improving the versatility of the equipment.

Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-3 This utility model provides a technical solution: a speaker processing mold, including a base 1 and a lower mold 2 disposed on the top of the base 1. Both ends of the top of the base 1 are provided with insert rods 3 extending out of the top of the lower mold 2, which are used to contact and be pressed down with the outer upper mold during mold closing, thereby converting the vertical movement of the upper mold into the linear downward movement of the insert rods 3 themselves. A bottom plate 4 is disposed at the middle of the top of the base 1, located inside the lower mold 2. The bottom plate 4 is located in the cavity of the lower mold 2. When the insert rods 3 descend, they are driven downwards to the mold cavity by a connecting mechanism 5. At the bottom of the cavity, the base 1 is equipped with a connecting mechanism 5. The connecting mechanism 5 includes a connecting rod 6 connected to the insert rod 3. A spring 7 is sleeved on the outside of the insert rod 3, which fits against the top of the connecting rod 6 and the bottom of the lower mold 2. When the insert rod 3 moves down, it is compressed and stores elastic potential energy. When the upper mold is disengaged, this potential energy is converted into kinetic energy, which drives the base plate 4 to reset upward through the connecting mechanism 5, thereby ejecting the molded product. This achieves a purely mechanical automatic demolding, without the need for additional hydraulic, pneumatic or electric systems to drive demolding. It has the advantages of simple structure and low energy consumption.
[0016] Specifically, such as Figure 3 As shown, a threaded block 301 is installed at the bottom of the insertion rod 3, and a threaded groove 602 that matches the size of the threaded block 301 is opened at the top of the connecting rod 6. The insertion rod 3 can be detachably installed through the threaded block 301 and the threaded groove 602, so that the insertion rod 3 can be easily replaced after long-term use and wear, avoiding the scrapping of the entire mold due to local wear, and effectively extending the overall service life of the mold.
[0017] Specifically, such as Figure 2 and Figure 3As shown, sliders 601 are installed at both ends of the connecting rod 6. The top of the base 1 is provided with a groove 101 that matches the size of the connecting rod 6 and the slider 601. The slider 601 and the groove 101 restrict the connecting rod 6 to move only in the vertical direction, ensuring that there is no deviation or jamming during the ejection process, and improving the stability and repeatability of the demolding action.
[0018] Specifically, such as Figure 4 As shown, an adjustment assembly 8 connected to the base plate 4 is provided at the middle of the top of the connecting rod 6. The adjustment assembly 8 includes an outer cylinder 801, an inner cylinder 802, and a motor 803. The outer cylinder 801 is detachably installed on the top of the connecting rod 6. The inner cylinder 802, whose top is in contact with the bottom of the base plate 4, is sleeved on the inner side of the outer cylinder 801. A cavity 603 is opened on one side of the connecting rod 6. The motor 803 is placed in the cavity 603. The output end of the motor 803 is connected to a threaded rod 804. The threaded rod 804 is threadedly connected to the inner wall of the inner cylinder 802. When the motor 803 drives the threaded rod 804 to rotate, it causes the inner cylinder 802 to move vertically up and down relative to the fixed outer cylinder 801, thereby precisely adjusting the height of the base plate 4 to meet the demolding requirements of audio speaker products of different depths (thicknesses).
[0019] Specifically, such as Figure 4 and Figure 5 As shown, a sleeve 9 is installed at the bottom of the base plate 4 and fitted onto the top of the inner cylinder 802. A guide block 10 is installed at the upper end of the inner cylinder 802. A lightning-shaped guide groove 901 is opened at the bottom of the sleeve 9 and is aligned with the guide block 10. The guide groove 901 includes an inclined inlet section, a horizontal locking section and a vertical positioning point. During installation, the guide block 10 must be aligned with the bottom opening of the guide groove 901, pushed up first and then rotated, and finally pushed up again to lock it. Disassembly requires pushing up, reversing, and then pushing up again. This multi-step operation mechanism effectively prevents accidental loosening due to vibration or accidental contact. While ensuring the reliability of the connection, it enables the rapid replacement of the base plate 4 and improves production flexibility.
[0020] Specifically, such as Figure 2 and Figure 4 As shown, the top of the base 1 is also provided with an installation groove 102 that communicates with the slide groove 101. The installation groove 102 is larger than the base plate 4, forming a rotation space for the base plate 4. The bottom of the base plate 4 is provided with multiple grooves 401 in an array to form hand gripping points, which facilitates the application of force and adjustment of angle when disassembling or installing the base plate 4, significantly improving operating efficiency and personnel safety.
[0021] In summary, the working principle of the speaker processing mold provided in this embodiment is as follows: When the upper mold is pressed down, it first contacts the insert rod 3 extending from the top surface of the lower mold 2 and applies a vertical downward pressure. The insert rod 3 transmits this external force to the connecting rod 6 through the threaded block 301 at its bottom, which drives the entire connecting mechanism 5 to overcome the elastic force of the spring 7 and slide smoothly downward along the slide groove 101. During this process, the spring 7 is compressed and stores a large amount of elastic potential energy. At the same time, the base plate 4, which is rigidly connected to the connecting mechanism 5, moves down to the bottom of the cavity of the lower mold 2 in sync, preparing for the filling and molding of the material.
[0022] After the molding process is completed, the upper mold begins to rise. The moment it disengages from the insert rod 3, the compressed spring 7 immediately releases its stored elastic potential energy. This energy pushes the connecting rod 6 to precisely return to its original position along the slide groove 101. Then, through the adjusting component 8, the base plate 4 is driven to rise steadily from the bottom of the cavity. The upper surface of the base plate 4 evenly ejects the molded speaker product, completing the fully automatic mechanical demolding action. The entire process requires no external power source, making it efficient and reliable.
[0023] When it is necessary to process speaker products of different depths and thicknesses, the motor 803 can be started. The motor 803 drives the threaded rod 804 to rotate. Through the threaded engagement with the inner wall of the inner cylinder 802, the rotational motion is converted into the precise linear lifting and lowering of the inner cylinder 802 relative to the fixed outer cylinder 801. The top of the inner cylinder 802 directly supports the bottom plate 4, thereby precisely adjusting the initial height and final ejection position of the bottom plate 4 in the cavity, realizing the rapid adaptation of the mold to different product sizes.
[0024] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
