Abstract
Description
Technical Field
[0001] This utility model relates to the field of acoustic diaphragm forming technology, and in particular to a dual-position forming equipment for large diaphragm plates. Background Technology
[0002] The diaphragm is a crucial component in a loudspeaker's sound production. The sound emitted by a loudspeaker is entirely derived from the diaphragm's movement pattern, which determines the loudspeaker's timbre and sound quality. As people's demands for loudspeaker sound effects increase, so too do their requirements for diaphragm quality.
[0003] A search revealed that the document with publication number "CN217591102U" states: "This utility model relates to the technical field, specifically to a multi-station diaphragm forming equipment, including a base, an electric cylinder, a mold, and mold head plates. Mold head plates are fixedly installed in the middle of the upper end of the base. This utility model overcomes the shortcomings of the prior art. By setting up an electric cylinder, a movable plate, a mold, and a track, when personnel need to form a film, the film material can first be placed above two sets of mold head plates, and then the position of the mold head plates can be adjusted to be directly below the mold. When the mold temperature rises to the set pressing temperature..." At this time, the operator can activate the electric cylinder, which will drive the movable plate to move downwards along the track and begin inflating and molding. Two sets of molds are fixedly connected below the movable plate. The molds can be simultaneously pressed down onto the mold head plate. After the temperature reaches the setting temperature, the molds can be cooled with water. Once the temperature drops to the set demolding temperature, the molds are lifted by the electric cylinder, thus completing the molding of the molded material. In use, by setting two molding mold stations, it enables multi-station simultaneous film formation, replacing the previous method of using only a single film formation station, greatly improving the efficiency of film production.
[0004] However, traditional diaphragm forming equipment has a limited number of molds, resulting in a small amount of film material that can be pressed at one time, leading to low production efficiency. Furthermore, when inflating a large number of diaphragms at once, it is easy to cause inaccurate air pressure control, which affects the stability and consistency of diaphragm forming.
[0005] Therefore, we provided a dual-position forming equipment for large diaphragm panels to solve the above problems. Utility Model Content
[0006] To overcome the above deficiencies, this utility model provides a dual-position forming equipment for diaphragm large plates, which aims to solve the problems mentioned above.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A dual-position forming device for diaphragm plates includes a forming table. Support frames are welded to the top of the left and right sides of the forming table. A forming assembly is provided on the upper side of the forming table. The forming assembly includes a lower mold template installed above the forming table. A snap-fit block is provided at the top of the lower mold template. A forming die head is installed above the snap-fit block. A hydraulic spindle is installed in the center of the support frame. A forming pressure plate is welded to the bottom of the hydraulic spindle. An upper mold template is provided at the bottom of the forming pressure plate.
[0009] As a further description of the above technical solution:
[0010] The lower mold template is arranged in two symmetrical groups, and the forming mold head is connected to the lower mold template by a slot. The forming mold heads are arranged in groups of two, and four groups of forming mold heads are installed on each group of the lower mold template.
[0011] As a further description of the above technical solution:
[0012] The upper template is connected to the lower template of the mold via a hydraulic spindle to form a lifting structure, and the upper template corresponds one-to-one with the forming die head.
[0013] As a further description of the above technical solution:
[0014] Air pumps are installed at both ends of the forming table, and connecting pipes are installed above each air pump. Air holes are evenly opened at the bottom of the upper template, and each air hole is connected to the connecting pipe.
[0015] As a further description of the above technical solution:
[0016] The connecting pipes are arranged in four groups, and each group of connecting pipes corresponds to two columns of upper templates.
[0017] As a further description of the above technical solution:
[0018] A connecting block is welded to the bottom of the lower mold template, and an adjusting electric control screw is installed on the inner side of the surface of the forming table. The connecting block and the adjusting electric control screw are connected by a thread. The lower mold template and the upper mold template form a back-and-forth moving structure through the adjusting electric control screw.
[0019] As a further description of the above technical solution:
[0020] The connecting block is provided with adjusting sliders on both sides, and the adjusting electric control screw is provided with adjusting slide rail. The adjusting slider and the adjusting slide rail are slidably connected.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] By setting up the molding components, during production, the air pump is started to inflate the air holes in the upper template through the connecting pipe, which improves the uniformity of the force on the diaphragm material between the upper template and the lower template of the mold, and further improves the uniformity and quality of diaphragm molding. At the same time, by grouping the upper templates, each group of upper templates is inflated separately, avoiding excessive inflation at one time, which would cause unstable air pressure between the diaphragms and affect the quality of diaphragm molding.
[0023] After one molding, the lower mold plate is moved as a whole by adjusting the rotation of the electric control screw, and another set of lower mold plates is moved to the bottom of the upper mold plate. Then the hydraulic spindle is started to perform diaphragm molding again. During the molding process, the operator can unload the diaphragm on the other set of lower mold plates or put new material on it, which improves the continuity of equipment use and the efficiency of diaphragm molding.

[0031] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figure 1-6 As shown, this utility model provides a technical solution: a dual-position forming device for diaphragm plates, including a forming table 1, support frames 2 welded to the top of the left and right sides of the forming table 1, a forming component 3 provided on the upper side of the forming table 1, the forming component 3 including a lower mold template 301 installed above the forming table 1, a snap-fit block 302 provided at the top of the lower mold template 301, a forming die head 303 installed above the snap-fit block 302, a hydraulic spindle 304 installed in the center of the support frame 2, a forming pressure plate 305 welded to the bottom end of the hydraulic spindle 304, and an upper template 306 provided at the bottom end of the forming pressure plate 305.
[0033] Furthermore, the lower mold platen 301 is arranged symmetrically in two sets, front and back. The forming die head 303 is connected to the lower mold platen 301 by a slot. The forming die heads 303 are arranged in groups of two rows. Each set of the lower mold platen 301 has four sets of forming die heads 303 installed. By setting multiple sets of forming die heads 303, the number of diaphragms that can be formed at one time can be increased. At the same time, different numbers of forming die heads 303 can be installed according to production needs, thereby improving production flexibility.
[0034] Furthermore, the upper template 306 forms a lifting structure with the lower template 301 of the mold through the hydraulic spindle 304. The upper template 306 and the forming die head 303 correspond one-to-one. In production, the diaphragm material is laid flat on the surface of the lower template 301 of the mold. Then the mold is heated. When the mold temperature rises to the set pressing temperature, the upper template 306 is lifted and lowered through the hydraulic spindle 304, thereby hot-pressing the diaphragm.
[0035] Furthermore, air pumps 307 are installed at both ends of the forming table 1, and connecting pipes 308 are installed above each air pump 307. Air holes 309 are evenly opened at the bottom of the upper template 306, and the air holes 309 are all connected to the connecting pipes 308. During the forming process, the air pumps 307 are started to inflate the air holes 309 in the upper template 306 through the connecting pipes 308, thereby improving the uniformity of the force on the diaphragm material between the upper template 306 and the lower template 301 of the mold, and further improving the uniformity and quality of the diaphragm forming.
[0036] Furthermore, four sets of connecting pipes 308 are provided, with each set of connecting pipes 308 corresponding to two columns of upper templates 306. By grouping the upper templates 306, each set of upper templates 306 can be inflated separately, avoiding excessive inflation at one time, which would cause unstable air pressure between diaphragms and affect the quality of diaphragm formation.
[0037] Furthermore, a connecting block 310 is welded to the bottom end of the lower mold platen 301, and an adjusting electric control screw 311 is installed on the inner side of the surface of the forming table 1. The connecting block 310 and the adjusting electric control screw 311 are connected by a thread. The lower mold platen 301 and the upper mold platen 306 form a back-and-forth moving structure through the adjusting electric control screw 311. After one forming, the lower mold platen 301 is moved as a whole by adjusting the rotation of the adjusting electric control screw 311, and another set of lower mold platens 301 is moved to the bottom of the upper mold platen 306. Then, the hydraulic spindle 304 is started to perform diaphragm forming again. During the forming process, the operator can unload the diaphragm on the other set of lower mold platens 301 or put new material on it, which improves the continuity of equipment use and the efficiency of diaphragm forming.
[0038] Furthermore, the connecting block 310 is provided with adjusting sliders 312 on both sides, and the adjusting electric control screw 311 is provided with adjusting slide rail 313. The adjusting sliders 312 and adjusting slide rail 313 are slidably connected. Through the slidable connection between adjusting sliders 312 and adjusting slide rail 313, the stability of the lower mold plate 301 during the movement process can be ensured, and the accuracy of diaphragm forming can be prevented from being affected by shaking or displacement.
[0039] Working principle: After installing the device in the working position and starting the equipment, the diaphragm material is laid flat on the surface of the lower mold plate 301. Then, the mold starts to heat up. When the mold temperature rises to the set pressing temperature, the hydraulic spindle 304 drives the lower forming plate 305 and the upper mold plate 306 to descend, cooperating with the lower mold plate 301 to hot-press the diaphragm. At the same time, the air pump 307 is started, and air is injected into the air holes 309 in the upper mold plate 306 through the connecting pipe 308 to ensure that the diaphragm material is subjected to force between the upper mold plate 306 and the lower mold plate 301. Uniformity is achieved, thereby improving the uniformity and quality of diaphragm forming. After one forming is completed, the rotation of the electric control screw 311 is adjusted to control the overall movement of the lower mold plate 301. Another set of unused lower mold plates 301 are moved to the lower mold plate 306 to prepare for the next round of diaphragm forming. During the forming process, the operator can unload the diaphragm on the formed lower mold plate 301 or put new material on it, thereby improving the continuity of equipment use and the efficiency of diaphragm forming. This completes the use process of the dual-position forming equipment for large diaphragm plates.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
