[0023] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0024] Reference Figure 1 and Figure 2 As shown, the mold used for making jewelry molds is a special mold used in the production of handicrafts, and it plays a significant role in the entire production process. However, most existing jewelry molds suffer from defects due to improper venting design during the injection process, leading to air bubbles in the glue and resulting in finished product defects. Furthermore, most existing injection molds lack venting structures. To ensure the orderly progress of the entire production process, a new mold for making jewelry molds is proposed, including a mounting base 1. The upper side of the mounting base 1 is provided with two guide pillars 11. A fixing frame 12 is provided at the top of the column 11. A mold assembly 2 is provided between the fixing frame 12 and the mounting base 1. The mold assembly 2 includes a lower mold 21 and an upper mold 22. The upper mold 22 slides vertically along the two guide columns 11, and an exhaust component 3 is provided inside the upper mold 22. The exhaust component 3 includes a first exhaust channel opened in the upper mold 22. The middle section of the first exhaust channel extends to both sides to form a second exhaust channel 222. A sliding air plug 31 is vertically slidably provided in the first exhaust channel. The outer periphery of the middle section of the sliding air plug 31 is concave. A third exhaust channel 311 is formed, the length of which is greater than the length of the second exhaust channel 222. The top of the sliding air plug 31 is provided with a limiting member for vertical sliding of the sliding air plug 31. The top of the lower mold 21 has a forming groove 211 that cooperates with the upper mold 22. The bottom of the sliding air plug 31 slides downwards and gradually abuts against the bottom of the forming groove 211, and is used to discharge gas from the forming groove 211. The installation of the base 1, guide post 11, and upper mold 22 achieves the goal of making the entire mold... The process is carried out in an orderly manner. The venting component 3 inside the upper mold 22 can achieve the purpose of venting the molded groove 211 by sliding the sliding air plug 31 upward after the upper mold 22 is inserted into the molding groove 211. This avoids the problem of poor glue injection effect caused by gas inside the molding groove 211 during the glue injection process. Furthermore, the setting of the limiting component can limit the vertical sliding of the sliding air plug 31 after venting, preventing the glue from pushing the sliding air plug 31 to move and causing deformation. This ensures that the glue injection process is carried out in an orderly manner.

[0025] It should be noted that the upper mold 22 is also provided with an injection port 4 for injecting material into the molding groove 211. The top of the injection port 4 is provided with a feed pipe section 41. The feed pipe section 41 is externally connected to an external feeding device. The external feeding device can inject the jewelry glue into the molding groove 211 through the feed pipe section 41 to realize the entire jewelry glue injection process.

[0026] Additionally, the specific structure of the aforementioned limiting component is as follows: the limiting component includes a fixing block 32 disposed on the top of the sliding air plug 31, and a screw 33 is rotatably disposed inside the fixing block 32. The screw 33 extends downward and is threadedly connected to the top of the upper mold 22. The fixing block 32 ensures that the downward sliding stroke of the entire sliding air plug 31 is determined, avoiding the problem of over-sliding. Furthermore, the screw 33 ensures that after the venting is completed, turning the screw 33 into the upper mold 22 can achieve the purpose of limiting and fixing the sliding air plug 31, thereby ensuring its stability.

[0027] It should also be noted that the bottom surface of the fixing block 32 is also provided with a limiting rod 321, the bottom of which abuts against the top surface of the upper mold 22; the setting of the limiting rod 321 can prevent the sliding air plug 31 from sliding down the stroke.

[0028] Furthermore, the top of the upper mold 22 is provided with a driving component 5 for driving the upper mold 22 to slide vertically. The driving component 5 is a telescopic cylinder 51, and the output end of the telescopic cylinder 51 extends downward and is located on the top of the upper mold 22. By operating the telescopic cylinder 51, the upper mold 22 can be driven to slide vertically closer to the lower mold 21 to achieve the purpose of mold closing. Moreover, the above-mentioned venting process is carried out after mold closing.

[0029] It is worth mentioning that a sealing strip 221 is also provided on the side of the upper mold 22. The sealing strip 221 can ensure that the above-mentioned glue injection process is orderly and stable.

[0030] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
