Description

Technical Field

[0001] This utility model relates to the field of hot runner processing technology, and in particular to a hot runner manifold that is easy to install. Background Technology

[0002] Injection molding technology has become a crucial production method in industrial manufacturing, offering advantages such as high production speed, high efficiency, and dimensional accuracy. It is widely used in the molding of plastic parts. The manifold in an injection mold, also known as a hot runner manifold, is a central component of the hot runner system in multi-cavity molds. It distributes the molten plastic from the main runner nozzles to each injection point nozzle via the runner system. The manifold ensures uniform filling of the mold cavity, balanced plastic flow, and balanced system heat.

[0003] Currently, most hot runner systems are integrated structures with fixed nozzle numbers and positions, making them suitable only for specific situations and thus having poor applicability.

[0004] Therefore, those skilled in the art provide a hot runner manifold that is easy to install in order to solve the problems mentioned in the background art. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a hot runner manifold that is easy to install. The main manifold has a transverse main manifold in the middle and a downward main manifold in the middle of the upper part of the main manifold, which connects to the main manifold. An injection nozzle is provided at the opening of the main manifold. A hot nozzle is provided on the secondary manifold. A secondary manifold has a secondary manifold in the middle and connects to the hot nozzle. A connecting pipe is provided between the secondary manifold and the main manifold. One end of the connecting pipe is inserted into the main manifold and can slide relative to the main manifold. A fastening component and a connector are provided on the connecting pipe. The fastening component is threaded to the main manifold, and the connector is used to seal the gap between the connecting pipe and the main manifold.

[0006] Preferably, the fastening components include sealing rings one and two, with a fixing flange two fixedly mounted on one end of the sealing rings one and two. The fixing flange two is a hexagonal sleeve, which can be easily rotated using a hexagonal wrench. A tapered portion is fixedly mounted on the other end of the sealing rings one and two.

[0007] Preferably, a mating hole is provided on the main diversion plate at the outer end of the main diversion channel. The outer section of the mating hole is a threaded hole that mates with the sealing rings one and two, the middle section of the mating hole is a tapered hole that mates with the tapered part on the sealing rings one and two, and the rear section of the mating hole is a groove that mates with the butt joint. When the sealing rings one and two are rotated inward by the fixed flange two, the end of the tapered part on the sealing rings one and two presses against the butt joint. The deformed butt joint is tightly attached to the outer wall of the connecting pipe and the inner wall of the mating hole, improving the sealing performance of the connection.

[0008] Preferably, sealing grooves are provided at equal intervals on the tapered portion of the sealing ring one and two ends. The sealing grooves facilitate the compression deformation of the tapered portion of the sealing ring one and two ends, so that the tapered portion can better clamp the connecting pipe when squeezed by the tapered hole.

[0009] Preferably, the connecting pipe has a flow channel at one end located in the main distribution channel, and the flow channel is connected to the center hole of the connecting pipe to facilitate the smooth entry of the injection molding material into the regulating gate.

[0020] Example 1

[0021] Please see Figure 1-3 This embodiment provides a hot runner manifold that is easy to install, including a main manifold 2 and a secondary manifold 3. The main manifold 2 has a transverse main manifold channel in its middle, and a downward main manifold channel in its upper middle section, which connects to the main manifold channel. An injection nozzle is provided at the opening of the main manifold channel. The secondary manifold 3 has a hot nozzle and a secondary manifold channel in its middle, which connects to the hot nozzle. A connecting pipe 1 is provided between the secondary manifold 3 and the main manifold 2, with one end of the connecting pipe 1 inserted into the main manifold channel and able to slide relative to it. The connecting pipe 1 is equipped with a fastening component and a connector 7. The fastening component is threadedly connected to the main runner plate 2, and the connector 7 is used to seal the gap between the connecting pipe 1 and the main runner. The connecting pipe 1 is coaxially connected to the runner to reduce pressure leakage in the runner and avoid the problem of pressure leakage in the runner caused by adding an extra connecting channel. It ensures stable filling pressure in the hot runner, and the injection point can be adjusted at will within the length range of the connecting pipe 1, which can better match the mold and is applicable to a wider range of molds, thus better meeting the usage requirements.

[0022] The fastening components include sealing rings 1 and 2 6, with a fixing flange 2 5 fixedly installed at one end of the sealing rings 1 and 2 6. The fixing flange 2 5 is a hexagonal sleeve, which can be easily rotated using a hexagonal wrench. A tapered part is fixedly installed at the other end of the sealing rings 1 and 2 6.

[0023] The main diversion plate 2 is provided with a mating hole at the outer end of the main diversion channel. The outer section of the mating hole is a threaded hole that mates with the sealing rings 1 and 2. The middle section of the mating hole is a tapered hole that mates with the tapered part of the sealing rings 1 and 2 6. The rear section of the mating hole is a groove that mates with the connector 7. When the sealing rings 1 and 2 6 are rotated inward by the fixing flange 2 5, the end of the tapered part of the sealing rings 1 and 2 6 presses against the connector 7. The deformed connector 7 is pressed tightly against the outer wall of the connecting pipe 1 and the inner wall of the mating hole, improving the sealing performance of the connection.

[0024] Sealing grooves 11 are evenly spaced on the tapered portion of one end of the sealing ring 12 6. The sealing grooves 11 facilitate the compression deformation of the tapered portion of one end of the sealing ring 12 6, so that the tapered portion can better clamp the connecting pipe 1 when squeezed by the tapered hole, and can further position the connecting pipe 1, and ensure the stability of the glue injection point positioning.

[0025] The connecting pipe 1 has a flow channel 8 at one end located in the main distribution channel. The flow channel 8 is connected to the center hole of the connecting pipe 1, which facilitates the smooth entry of the injection molding material into the regulating gate. The other end of the connecting pipe 1 is provided with a tapered head and an annular groove. A sealing ring 9 is fitted inside the annular groove. A fixing flange 4 is provided on the connecting pipe 1 at the tapered head. The fixing flange 4 is fixedly connected to the secondary distribution plate 3 by fixing screws 10.

[0026] The outer end of the secondary diversion channel on the secondary diversion plate 3 is provided with a matching tapered hole, which matches the tapered head at the end of the connecting pipe 1.
