Description

Technical Field

[0001] The utility model relates to the technology of stamping product production field, in particular to an ultra-long C-shaped product die forming structure. Background Art

[0002] A speaker is a device that converts audio signals into sound. To put it simply, the audio signal is amplified and then released by the speaker so that the user can hear the sound. In order to protect its internal components, existing speakers are equipped with mesh covers to protect them. However, since speakers are extremely fragile, there are many factors that can affect the sound quality of the speakers.

[0003] Speakers are used in a variety of scenarios, such as homes, offices, public places, etc. According to different application scenarios, speakers are designed into various strange shapes. For some extra-long audio equipment, the grilles are also extra-long, belonging to extra-long C-shaped products, and their length can reach more than 1 meter. Such extra-long C-shaped products are generally stamped using a stamping die in conjunction with a punch press.

[0004] In the prior art, the main structure of the stamping die used to form super-long C-shaped products includes a lower die, an upper die and a core pulling mechanism; the upper die can be movably arranged above the lower die; the core pulling mechanism is arranged on the lower die and located between the lower die and the upper die, and the core pulling mechanism is a single-head core pulling mechanism, which includes a mold core and a driving mechanism, and the driving mechanism drives the mold core to move back and forth horizontally to achieve core pulling from the super-long C-shaped product. Since the stamping die needs to be centrally arranged on the punch press, the length of the punch press is at least three times the length of the super-long C-shaped product. The production enterprise needs to purchase an extra-large punch press, and the punch press occupies a very large area. In addition, the time required for core pulling is long, resulting in very low production efficiency. In addition, since there is only one mold core, the length is long, and the manufacturing difficulty is large, resulting in a high overall manufacturing cost of the stamping die. Utility Model Content

[0005] In view of this, the utility model aims to address the deficiencies in the prior art, and its main purpose is to provide an extra-long C-shaped product mold forming structure, which can effectively solve the problems of high cost, low production efficiency and the need to use an extra-large punch press in the existing stamping molds.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A super-long C-shaped product mold forming structure includes a lower mold, an upper mold and a core pulling mechanism; the upper mold can be movably arranged up and down directly above the lower mold; the core pulling mechanism is arranged on the lower mold and is located between the lower mold and the upper mold; the core pulling mechanism is a two-end core pulling mechanism, which includes two mold cores and two driving mechanisms; the two mold cores are arranged horizontally relative to each other and both extend horizontally, and the two mold cores can be movably arranged on the lower mold horizontally, and a cavity for molding super-long C-shaped products is formed between the two mold cores and the lower mold and the upper mold; the two driving mechanisms are both arranged on the lower mold and respectively drive the two mold cores to move horizontally back and forth to splice or separate from each other.

[0008] As a preferred solution, the lower mold includes a lower mold plate and a guide rail, which is fixed on the surface of the lower mold plate and extends laterally. The two mold cores can be installed on the guide rail for sliding back and forth laterally, so that the two mold cores can move back and forth laterally more smoothly and perform core pulling better.

[0009] As a preferred solution, the guide rail has an I-shaped structure, and its upper surface has two dovetail blocks, which are arranged longitudinally at intervals and extend laterally. The bottom surfaces of the two mold cores are concavely provided with two dovetail grooves, and the two dovetail blocks are embedded in the two dovetail grooves and installed in relative sliding cooperation, so that the two mold cores are installed stably and not easy to derail.

[0010] As a preferred solution, the driving mechanism includes a driving cylinder and a movable frame. The driving cylinder is fixed on the lower mold, and the movable frame is connected between the outer end of the mold core and the piston rod of the driving cylinder. It has a simple structure and is convenient for core pulling.

[0011] As a preferred solution, there are two driving cylinders, which are respectively located at the front and rear sides of the mold core, and the piston rods of the two driving cylinders are fixedly connected to the movable frame to make the mold core move more smoothly and quickly.

[0012] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0013] By adopting a two-end core pulling mechanism, which includes two mold cores and two driving mechanisms, the two driving mechanisms respectively drive the two mold cores to move back and forth horizontally to splice or separate each other. During the production process, it is possible to simultaneously pull the core from both ends of the super-long C-shaped product. The length of the punch press only needs to be twice the length of the super-long C-shaped product. The production company does not need to purchase an additional super-large punch press, and the punch press area is effectively reduced. In addition, the core can be pulled at the same time, which greatly shortens the core pulling time, thereby effectively improving production efficiency. In addition, due to the short length of the mold core and the low difficulty of production, the overall production cost of the mold is greatly reduced.

In this embodiment, the two mold cores 31 can be installed on the guide rail 12 to slide back and forth horizontally, so that the two mold cores 31 can move back and forth horizontally more smoothly and perform core pulling better. In addition, the bottom surfaces of the two mold cores 31 are concavely provided with two dovetail grooves 311, and the two dovetail blocks 121 are embedded in the two dovetail grooves 311 and installed in a relatively sliding manner, so that the two mold cores 31 are installed firmly and are not easy to derail. The driving mechanism 32 includes a driving cylinder 321 and a movable frame 322, the driving cylinder 321 is fixed on the lower mold 10, and the movable frame 322 is connected between the outer end of the mold core 31 and the piston rod of the driving cylinder 321, with a simple structure and convenient core pulling.

Then, the two driving mechanisms 32 respectively drive the two die cores 31 to move laterally outward, so that the two die cores 31 are separated from each other and pulled out of the extra-long C-shaped product 40. Then, the punch drives the upper die 20 to move upward to open the die with the lower die 10. Finally, the extra-long C-shaped product 40 is taken out from the space between the upper die 20 and the lower die.

[0032] The design focus of the utility model is: by adopting a two-end core pulling mechanism, which includes two mold cores and two driving mechanisms, the two driving mechanisms respectively drive the two mold cores to move back and forth horizontally to splice or separate each other.
