Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to an explosion-proof valve panel mold. Background Technology

[0002] The explosion-proof valve panel is a key component of the explosion-proof valve control box, responsible for command input, status feedback, and safety interlock functions. Its design must balance the explosion-proof protection level (such as G24 level) with the intuitiveness of user operation (such as LCD Chinese menu), and it is widely used in the storage and transportation of flammable and explosive media, dusty environments, and emergency protection systems.

[0003] Explosion-proof valve panel molds are special molds used for stamping and processing precision pressure relief structures on the surface of battery casings (especially power batteries for new energy vehicles). Their core function is to efficiently form explosion-proof holes or explosion-proof valve plates that meet safety standards on thin-walled metal casings.

[0004] The existing patent "CN118950833B" proposes a die for punching explosion-proof valve holes in the outer shell of a battery cell, including: an upper die base; a lower die base; a cantilever beam disposed on the lower die base; a sliding seat disposed on the upper side of the cantilever beam and vertically sliding; a first reset member for resetting the sliding seat upwards; a lower punch disposed on the upper side of the cantilever beam; and an upper die disposed on the upper die base.

[0005] However, the existing explosion-proof valve panel mold has a relatively simple structure and lacks a certain locking and fixing structure, which makes it impossible to quickly lock and fix the panel, thus affecting the processing efficiency of the explosion-proof valve panel. Utility Model Content

[0006] The purpose of this utility model is to solve the problem mentioned in the background art that the explosion-proof valve panel mold lacks a certain locking and fixing structure, making it impossible to quickly lock and fix the panel, and proposes an explosion-proof valve panel mold.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An explosion-proof valve panel mold includes a lower mold and an upper mold, which are connected by a connecting block. Multiple fixing bolts are threaded onto the connecting block. Both the upper and lower molds have threaded holes corresponding to the fixing bolts. A rotating shaft is rotatably connected to one end of the connecting block. The lower mold has a lower mold cavity, and the upper mold has an opening corresponding to the lower mold cavity. Multiple clamping pins are rotatably connected to the edge of the lower mold cavity. A through groove corresponding to the clamping pins is provided on the inner wall of the opening. A connecting rod is fixedly sleeved on each clamping pin. The connecting rod is connected to the rotating shaft via a tension spring. A handle is fixedly connected to one end of the rotating shaft, and a limiter corresponding to the handle is fixedly connected to the top of the upper mold.

[0009] Preferably, the top edge of the lower mold is fixedly connected with multiple limiting posts.

[0010] Preferably, the lower mold has multiple fastening openings around its perimeter.

[0011] Preferably, the limiter includes a fixing block, a limit rod is slidably inserted into the fixing block, and the handle is provided with a limit hole corresponding to the limit rod.

[0012] Preferably, a stop bar corresponding to the connecting rod is fixedly connected to the inner wall of the lower mold.

[0013] Preferably, the rotating shaft is provided with a groove corresponding to the tension spring.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, the quick-locking mechanism enables the mold to quickly lock and fix the panel, thereby effectively improving the processing efficiency of the explosion-proof valve panel.

[0016] 2. The fixing bolts in this utility model can facilitate the fixing and disassembly of the connecting block. At the same time, the limiting post can limit the position of the upper mold, the fastening port can facilitate the fixing of the lower mold, the limiting rod can effectively fix the handle, and the stop rod can limit the connecting rod.

A stop rod 13 corresponding to the connecting rod 7 is fixedly connected to the inner wall of the lower mold 1 to limit the connecting rod 7. The connecting rod 7 is connected to the rotating shaft 5 through a tension spring 8. The rotating shaft 5 is provided with a groove corresponding to the tension spring 8 to drive the connecting rod 7 to rotate.

[0026] In this embodiment, a handle 9 is fixedly connected to one end of the rotating shaft 5 to drive the rotating shaft 5 to rotate. A limiter corresponding to the handle 9 is fixedly connected to the top of the upper mold 2 to limit and fix the handle 9.
