Description

Technical Field

[0001] This utility model relates to the field of molecular isolation ring production technology, specifically an industrial molecular isolation ring die casting mold. Background Technology

[0002] Molecular isolation rings are a special type of seal. Their function is to form a thin film between two contact surfaces to prevent gas or liquid leakage, while reducing friction and wear. They are mainly used in industrial applications with high precision and high vacuum requirements, such as semiconductor manufacturing, vacuum equipment, and laboratory instruments. Because the molecular isolation rings have very high requirements for dimensional accuracy, they are currently mostly produced using die-casting molds to control dimensional errors. However, in traditional die-casting technology, there is a lack of effective stabilization measures between the upper and lower molds after the mold is closed. This makes it very easy for the molecular isolation rings to be affected by positional shifts between the upper and lower molds during the casting process.

[0003] To address these issues, this invention provides an industrial molecular isolation ring die-casting mold. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: Please see Figure 1-4 An industrial molecular isolation ring die casting mold, comprising: The lower mold base 1 and the upper mold base 3 are provided. The top of the lower mold base 1 is provided with a lower cavity 2, and the bottom of the upper mold base 3 is provided with an upper cavity 4 that mates with the lower cavity 2. The top of the upper mold base 3 is provided with a gate 5. Multiple stabilizing plates 6 are respectively assembled on both sides of the upper mold base 3. The bottom end of the stabilizing plate 6 is provided with a stabilizing protrusion 7. The two sides of the lower mold base 1 are provided with limiting components 8 corresponding to the stabilizing plates 6. The limiting components 8 are used to cooperate with the stabilizing plates 6 and the stabilizing protrusions 7 to form a reinforcement between the lower mold base 1 and the upper mold base 3. More specifically, since the heat dissipation fin ventilation groove of the molecular isolation ring is relatively narrow, in order to ensure the dimensional accuracy of the heat dissipation fin ventilation groove of the molecular isolation ring, in this embodiment, both the lower cavity 2 and the upper cavity 4 are directly processed by a high-precision CNC machine tool. Compared with EDM processing, the dimensional tolerance of the casting can be guaranteed. In this embodiment, the gate 5 is located in the middle of the upper mold base 3 so that the molecular isolation ring can be better filled and molded; Please refer to Figure 2 In this embodiment, the four corners of the bottom of the upper mold base 3 are fixedly connected with insert rods 15, and the top of the lower mold base 1 is provided with clearance holes 16 corresponding to the insert rods 15, and the insert rods 15 are inserted into the clearance holes 16. More specifically, through the structural cooperation of the insert rod 15 and the clearance hole 16, when the upper mold base 3 approaches the lower mold base 1, the insert rod 15 will be pre-inserted into the clearance hole 16, thereby guiding the assembly position of the upper mold base 3 and preventing the upper mold base 3 from deviating. Please refer to Figure 2 In this embodiment, vacuum interfaces 18 are fixedly connected to both sides of the bottom of the upper mold base 3, and one end of the vacuum interface 18 located inside the upper cavity 4 is connected to the upper cavity 4. Meanwhile, both sides of the top of the lower mold base 1 are fixedly provided with receiving grooves 17 corresponding to the vacuum interface 18. With the setting of the receiving grooves 17, after the upper mold base 3 and the lower mold base 1 are closed, part of the vacuum interface 18 will be stored in the receiving grooves 17, so as to avoid the presence of the vacuum interface 18 from affecting the closing of the lower mold base 1 and the upper mold base 3. More specifically, by setting the vacuum interface 18, after the lower mold base 1 and the upper mold base 3 are closed, the vacuum equipment is connected to the vacuum interface 18, which can extract the gas inside the lower cavity 2 and the upper cavity 4, so that the lower cavity 2 and the upper cavity 4 reach a suitable vacuum state. Please refer to Figure 3 In this embodiment, mounting holes corresponding to the stabilizing plate 6 are provided on both sides of the upper mold base 3, and the stabilizing plate 6 is connected to the corresponding mounting holes by screws. More specifically, the mounting holes allow the stabilizing plate 6 to be stably mounted on the upper mold base 3 with the help of screws. When the stabilizing protrusion 7 does not perform well, the screws can be removed from the upper mold base 3 to replace the stabilizing plate 6. Please refer to Figure 4 In this embodiment, the top and bottom ends of the stabilizing protrusion 7 are provided with inclined surfaces that move towards the middle of the stabilizing protrusion 7, and a wear-resistant layer is provided on the inclined surfaces. More specifically, by setting the inclined surface, during the mold closing process of the upper mold base 3 and the lower mold base 1, the inclined surface located below will contact the extension rod 11. In combination with the characteristics of the inclined surface, as the upper mold base 3 continues to move downward, the stabilizing protrusion 7 will squeeze the extension rod 11, causing the stop plate 10 to make adaptive adjustments under the support of the rotating shaft. More specifically, by setting a wear-resistant layer, the wear of the extension rod 11 when it comes into contact with the inclined surface can be reduced, thereby increasing the service life of the extension rod 11 and the stabilizing protrusion 7. More specifically, the wear-resistant layer can be made of rubber; Example 2: Please see Figure 1-4 This embodiment provides a technical solution based on Embodiment 1: the limiting component 8 includes: Positioning seat 9 is fixedly connected to the outside of the lower mold base 1. A stop plate 10 is rotatably connected to the middle of the positioning seat 9. An extension rod 11 is fixedly connected to the top of the stop plate 10. A waist hole 12 is opened at the top of the positioning seat 9. The reset component is assembled inside the waist hole 12 and is used to drive the stop plate 10 back to the initial position when the stop plate 10 is not under pressure. Please refer to Figure 4 In this embodiment, a support groove is provided in the middle of the positioning seat 9, and the stop plate 10 is connected to the inside of the support hole through a rotating shaft; More specifically, the support grooves allow the positioning seat 9 to have space for mounting the pivot. Furthermore, the support groove is U-shaped. Through the structural characteristics of the support groove, both ends of the rotating shaft can be assembled simultaneously, thereby balancing the weight at both ends of the rotating shaft and ensuring the stability of the stop plate 10 during application. Please refer to Figure 4In this embodiment, the reset component includes: a light rod 13, which is movably connected inside the waist hole 12, and one end of the light rod 13 near the stop plate 10 is fixedly connected to the stop plate 10. A helical spring 14 is sleeved on the outside of the light rod 13, and the two ends of the helical spring 14 are fixedly connected to the stop plate 10 and the positioning seat 9, respectively.

[0017] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0018] The working principle is as follows: First, the upper mold base 3 is moved downward. As the upper mold base 3 continues to move, the extension rod 11 will contact the stabilizing protrusion 7 located below in advance. The stabilizing protrusion 7 will squeeze the extension rod 11, so that the stop plate 10 will rotate under the support of the positioning seat 9. Since the helical spring 14 is located between the positioning seat 9 and the stop plate 10, the helical spring 14 will deform during the rotation of the stop plate 10. After the extension rod 11 passes the stabilizing protrusion 7 located below, the extension rod 11 loses its compression and, under the elastic potential energy of the helical spring 14, can drive the stop plate 10 to rotate towards the stabilizing plate 6, causing the extension rod 11 to fit tightly against the stabilizing plate 6, thereby forming a stabilizing support after the lower mold base 1 and the upper mold base 3 are closed, avoiding uncontrollable displacement between the lower mold base 1 and the upper mold base 3, and ensuring the dimensional accuracy of the molecular isolation ring.
