Description

Technical Field

[0001] The utility model relates to the technical field of inner mold cores, in particular to a sealing ring structure for an inner mold core of a mold. Background Art

[0002] On-site machining of mold sealing ring grooves can result in certain errors, affecting the sealing effectiveness of the water channel. Furthermore, due to the characteristics of plastic materials, many products require very high mold temperatures (>100°C) during injection molding. After a period of mass production, the sealing rings age and leaks from the mold bottom surface can occur, impacting production progress. Utility Model Content

[0003] (1) Technical problems solved

[0004] In view of the deficiencies in the prior art, the present invention provides a sealing ring structure for a mold core in a mold, which solves the problems raised in the above-mentioned background technology.

[0005] (2) Technical solution

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a sealing ring structure for a mold core, comprising a B plate, wherein the B plate is provided with a rear mold core connected to the B plate, the rear mold core is provided with a water pipe assembly that can be arranged along the interior of the rear mold core, and the rear mold core is provided with a sealing ring assembly that can cooperate with the water pipe assembly and can seal the rear mold core.

[0007] Furthermore, the water pipe assembly includes a first water pipe and a second water pipe, and the second water pipe is connected to the first water pipe; the sealing ring assembly includes a first sealing ring and a second sealing ring, and the first sealing ring and the second sealing ring are arranged in parallel at the connection between the second water pipe and the first water pipe.

[0008] Furthermore, the bottom end of the second water pipe is connected to the top end of the first water pipe, the second water pipe and the first water pipe are arranged in the rear mold core, the second sealing ring is arranged at the connection between the second water pipe and the first water pipe, and the second sealing ring is arranged in the first sealing ring.

[0009] Furthermore, the second sealing ring is located above the first sealing ring.

[0010] Furthermore, the first water pipe is in an L-shape, the second water pipe is in an L-shape, a straight-line shape or an S-shape, and the diameter of the second sealing ring is greater than the diameter of the first sealing ring.

[0011] Setting two sealing rings in parallel on the pipeline usually means installing two independent sealing rings at the same connection or adjacent positions of the pipeline system to achieve a higher level of sealing effect. This setting method is mainly based on the following considerations:

[0012] 1. Enhance sealing performance

[0013] 1. **Double Protection**: The two sealing rings work simultaneously to form a double sealing barrier. Even if one of the sealing rings leaks or is damaged slightly, the other sealing ring can still maintain the sealing effect, thereby greatly reducing the risk of overall leakage.

[0014] 2. **Increase sealing pressure**: In some high-pressure piping systems, the sealing capacity of a single sealing ring may not be sufficient to withstand the high-pressure environment. By installing two sealing rings in parallel, the sealing pressure can be dispersed, improving the pressure-bearing capacity of the entire sealing system.

[0015] 2. Extend service life

[0016] 1. **Shared Wear**: During pipeline operation, seals are subject to wear due to various factors, including medium flow, temperature changes, and vibration. Installing two seals in parallel can share this wear and extend their service life.

[0017] 2. **Mutual backup**: When one of the sealing rings reaches the end of its service life and needs to be replaced, the other sealing ring can still maintain the sealing effect, providing a time buffer for the continuous operation of the pipeline.

[0018] Compared with the prior art, the sealing ring structure for the mold core of the mold has a better sealing effect by using two sealing rings, effectively improves the problem of mold leakage during mass production, extends the service life of the mold and ensures continuous production.
