Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology, and in particular to a refrigerant flow channel plate sealing device. Background Technology

[0002] Runner plates are core components used for precise fluid distribution. In injection molds, they act as manifolds in the hot runner system, ensuring that molten plastic fills multiple mold cavities uniformly and with insulation, enabling efficient and automated production. Runner plate airtightness testing typically employs a pressure monitoring method. After sealing all nozzles, compressed air is injected into the runner, and pressure changes are monitored using high-precision sensors to determine airtightness. However, due to the numerous sealing openings and significant shape deformation of runner plates, the sealing performance can be unstable, resulting in a short lifespan for the sealing rings.

Detailed Implementation

[0016] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0017] First, combine Figs. 1-7 This invention describes a refrigerant flow channel plate sealing device according to an embodiment of the present invention, used for testing the airtightness after sealing the refrigerant flow channel plate 7.

[0018] like Figs. 1-7 As shown, a refrigerant flow channel plate sealing device according to an embodiment of the present invention includes: a frame assembly, a sealing assembly, and a detection mechanism; The frame assembly includes: a positioning mechanism 1, a pressure plate mechanism 2, and a push plate mechanism 3; The positioning mechanism 1 is provided with a flow channel plate 7, the flow channel plate 7 has a plurality of sealing openings, the pressure plate mechanism 2 is located above the flow channel plate 7, and the push plate mechanism 3 is located on the side of the flow channel plate 7. The sealing assembly includes: a core-pulling sealing mechanism 4 and a spherical sealing mechanism 5; The output ends of the pressure plate mechanism 2 and the push plate mechanism 3 are each provided with a plurality of core-pulling sealing mechanisms 4 and spherical sealing mechanisms 5. The core-pulling sealing mechanism 4 is set for the sealing opening, and the spherical sealing mechanism 5 is set for the sealing opening that the core-pulling sealing mechanism 4 cannot seal. The testing mechanism is used to test the airtightness of the flow channel plate 7.

[0019] This application uses a positioning mechanism 1 to position the flow channel plate 7, and a pressure plate mechanism 2 and a push plate mechanism 3 to move the core-pulling sealing mechanism 4 and the spherical sealing mechanism 5, so that the core-pulling sealing mechanism 4 and the spherical sealing mechanism 5 can seal the sealing opening on the flow channel plate 7. The detection mechanism performs an airtightness test on the flow channel plate 7 after sealing, so as to achieve a stable seal on the sealing opening of the flow channel plate 7 and extend the life of the sealing ring.

[0020] like Figs. 4-5 As shown, the core-pulling sealing mechanism 4 includes: a cylinder 41, a piston rod 42, a sealing head 43, and a core-pulling sealing ring 44; The cylinder body 41 is fixed on the pressure plate mechanism 2 or the push plate mechanism 3. The piston rod 42 is located inside the cylinder body 41 and slides within the cylinder body 41. One end of the piston rod 42 is connected to the sealing head 43. A core-pulling sealing ring 44 is provided between the sealing head 43 and the cylinder body 41. The sealing head 43 is located at the sealing opening. The sealing head 43 has a stepped portion, which is provided corresponding to the edge of the sealing opening.

[0021] In this embodiment, during the downward movement of the cylinder 41, the sealing head 43 contacts the sealing port, and the stepped portion of the sealing head 43 is squeezed against the edge of the sealing port, causing the core-pulling sealing ring 44 to deform. The distance between the sealing head 43 and the cylinder 41 decreases, and the sealing head 43 pushes the piston rod 42 to move upward in the cylinder 41, so that the core-pulling sealing ring 44 seals the sealing port, reducing the friction when the core-pulling sealing ring 44 is inserted into the sealing port, improving the service life of the core-pulling sealing ring 44, and the stability of the core-pulling external expansion type sealing is also much higher than that of the end face sealing on the market.

[0022] The detection mechanism includes: a detector and a detection tube 6; The detection tube 6 is mounted on one of the core-pulling and sealing mechanisms 4. A detection hole is provided in the piston rod 42 of the core-pulling and sealing mechanism 4. The detection hole is connected to the sealing port. One end of the detection tube 6 passes through the cylinder 41 and is connected to the detection hole. The other end of the detection tube 6 is connected to the detector. The detector is used to detect airtightness.

[0023] In this embodiment, the detector is an existing airtightness testing device. After the sealing ports on the flow channel plate 7 are sealed, the detection tube 6 is connected to the detection hole through the detector, and the airtightness of the flow channel plate 7 is tested through the detection hole.

[0024] like Fig. 6 As shown, the spherical sealing mechanism 5 includes: a pressure rod 51, a pressure head 52, a spring 53, a sealing block 54, and a spherical sealing ring 55; One end of the pressure rod 51 is slidably mounted on the pressure plate mechanism 2 or the push plate mechanism 3, and the other end of the pressure rod 51 is provided with a pressure head 52. A spring 53 is sleeved on the pressure rod 51, and the spring 53 is located between the pressure head 52 and the pressure plate mechanism 2 or the push plate mechanism 3. The sealing block 54 is provided on the pressure head 52, and the spherical sealing ring 55 is provided on the sealing block 54. The spherical sealing ring 55 is provided corresponding to the sealing opening.

[0025] The sealing block 54 is provided with a pressure ring, which is sleeved on the sealing block 54. The pressure ring is provided at the edge of the sealing opening. The spherical sealing ring 55 is provided at the connection between the pressure ring and the sealing block 54. The sealing opening is provided with rounded corners at the location corresponding to the spherical sealing ring 55.

[0026] In this embodiment, during the downward movement of the pressure plate 21 driven by the pressure plate drive component, the pressure head 52 is pushed by the elastic force of the spring 53, causing the sealing block 54 to move into the sealing opening. The lower end of the pressure head 52 pushes the pressure ring on the sealing block 54, causing the spherical sealing ring 55 to seal the rounded corner of the sealing opening, reducing the wear of the spherical sealing ring 55 during sealing and improving the service life of the spherical sealing ring 55.

[0027] The positioning mechanism 1 includes: a base plate 11, a positioning plate 12, a support base 13, and a limiting post 14; The base plate 11 is provided with a plurality of positioning plates 12, which are used to position the flow channel plate 7. The support base 13 is provided on the base plate, and one end of the limiting post 14 is slidably disposed in the support base 13, and the other end is connected to the pressure plate mechanism 2.

[0028] The pressure plate mechanism 2 includes: a pressure plate 21 and a pressure plate driving component; The pressure plate 21 is located above the flow channel plate 7. The pressure plate 21 is connected to the limiting post 14, the core pulling and sealing mechanism 4 and the spherical sealing mechanism 5. The pressure plate driving component is used to drive the pressure plate 21 to move vertically.

[0029] The push plate mechanism 3 includes: a push plate 31, a slider 32, a slide rail 33, and a push plate drive component; The slide rail 33 is mounted on the base plate 11, the slider 32 is slidably mounted on the slide rail 33, the push plate 31 is mounted on the slider 32, the push plate 31 is connected to the core-pulling sealing mechanism 4 and the spherical sealing mechanism 5, and the push plate drive is used to drive the push plate 31 to move horizontally.

[0030] In this embodiment, both the pressure plate drive and the push plate drive are existing driving devices, which can be cylinders. The structure of the slider 32 and the slide rail 33 ensures that the push plate 31 moves linearly. The structure of the support base 13 and the limiting post 14 ensures that the pressure plate 21 moves linearly, while limiting the downward movement distance of the pressure plate 21 to avoid excessive pushing and damage to the spherical sealing ring 55.

[0031] Above, refer to Figs. 1-7 This invention describes a refrigerant flow channel plate sealing device according to an embodiment of the present invention. The flow channel plate 7 is positioned by a positioning mechanism 1, and the core-pulling sealing mechanism 4 and the spherical sealing mechanism 5 are moved by a pressure plate mechanism 2 and a push plate mechanism 3, so that the core-pulling sealing mechanism 4 and the spherical sealing mechanism 5 seal the sealing opening on the flow channel plate 7. The detection mechanism performs airtightness detection on the sealed flow channel plate 7 to achieve stable sealing of the sealing opening of the flow channel plate 7 and extend the life of the sealing ring.
