Description

Technical Field

[0001] This utility model relates to the technical field of vent plugs, and in particular to a mirror-sealed vent plug head structure. Background Technology

[0002] A vent plug is a mold accessory used inside a mold to expel air and other impurities, thereby improving the quality of the molded product. Other names include: honeycomb vent plug, breather plug, ventilation plug, and cylindrical vent plug. Aluminum vent plugs pose a high risk of scratching the product, potentially causing damage to its appearance, performance degradation, and affecting product quality. Vent plugs made of nylon or other plastics suffer from helium absorption and insufficient strength. Helium absorption significantly impacts the accuracy of helium testing. Insufficient strength also causes deformation and damage under pressure or external force, resulting in an inability to achieve the desired sealing effect. Vent plugs made of POM with a threaded connection to a stainless steel adapter have a high probability of leakage, and this sealing structure has a short lifespan and is cumbersome and time-consuming to repair. When a vent plug is machined into a single piece using POM material, the plug's strength is greatly reduced, making it prone to breakage. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a mirror-sealed vent plug structure with suitable strength, which reduces the impact of the plug on the product and inspection results, improves the sealing performance, and makes installation, disassembly and replacement more convenient in actual operation.

[0004] This utility model discloses a mirror-sealed vent plug structure, including a G1 / 4 quick-connect fitting, a POM vent plug, an adapter, and a connecting component. The top of the POM vent plug is connected to the G1 / 4 quick-connect fitting via the adapter, and the bottom of the POM vent plug is fitted with the connecting component. The vent plug made of POM has suitable strength, will not scratch the product, and will not cause helium absorption, greatly reducing the impact of the plug on the product and inspection results. The adapter and the POM vent plug form a mirror seal, which greatly improves the sealing performance and makes installation, disassembly, and replacement more convenient in actual operation.

[0005] Preferably, the adapter includes a 304 adapter, which achieves a mirror seal with the POM vent plug via an O-ring; the G1 / 4 quick connector is connected to the other side of the 304 adapter with threaded adhesive or Teflon tape. The new sealing structure adds a 304 adapter to form a mirror seal with the POM vent plug, greatly improving the sealing performance.

[0006] Preferably, the connecting component includes a through-hole bolt, which passes through the POM vent plug and connects to the internal thread of the 304 adapter; the through-hole bolt secures the 304 adapter and the POM vent plug, ensuring the strength of the sealing structure and making installation, disassembly, and replacement more convenient in actual operation.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: the vent plug made of POM has suitable strength, which will not scratch the product or cause helium absorption, greatly reducing the impact of the plug on the product and inspection results. The conversion component and the vent plug made of POM form a mirror seal, which greatly improves the sealing performance and makes installation, disassembly and replacement more convenient in actual operation.

[0013] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0014] like Figures 1 to 4 As shown, the 304 adapter 2 and the POM vent plug 3 achieve a mirror seal through an O-ring. The G1 / 4 quick-connect fitting 1 is connected to the other side of the 304 adapter 2 with thread-locking adhesive or Teflon tape. The new sealing structure adds a mirror seal between the 304 adapter 2 and the POM vent plug, greatly improving the sealing performance. The through-hole bolt 4 passes through the internal thread of the POM vent plug 3 and connects to the 304 adapter 2. The through-hole bolt 4 is used to fix the 304 adapter 2 and the POM vent plug 3, ensuring the strength of the sealing structure. This makes installation, disassembly, and replacement more convenient in actual operation.

[0015] like Figures 1 to 4As shown, this utility model discloses a mirror-sealed vent plug structure. During operation, the vent plug made of POM has suitable strength, which will not scratch the product or cause helium absorption, greatly reducing the impact of the plug on the product and inspection results. The new sealing structure adds a 304 material adapter to form a mirror seal with the POM material vent plug, improving the sealing performance. It is fixed by vent bolts to ensure the strength of the sealing structure.

[0016] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
