Description

Technical Field

[0001] This utility model relates to the field of hot runner processing technology, specifically a split-type hot runner system. 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 a fixed number of nozzles and their relative positions to the manifold, making them suitable only for specific situations and having poor applicability.

[0004] Therefore, those skilled in the art have provided a split-type hot runner system to solve the problems mentioned in the background art. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A split-type hot runner system includes a main manifold, a secondary manifold, an injection nozzle, and a hot nozzle. The injection nozzle is located on the upper part of the main manifold, and the hot nozzle is located on the lower part of the secondary manifold. The flow channel inside the hot nozzle is connected to the flow channel inside the secondary manifold. The discharge ends of the flow channels of the main manifold and the secondary manifold are respectively provided with quick-detachable connectors or plugs. A flow channel pipe is provided between two corresponding connectors on the main manifold and the secondary manifold, and the connectors are threaded to both ends of the flow channel pipe.

[0008] Preferably, the main diverter plate and the secondary diverter plate each have mounting holes at their respective diverter outlet ends, and these mounting holes are compatible with the connector and the plug.

[0009] Preferably, the connector includes a connecting part, a limiting part one, a connecting ring, and a flow channel hole. The connecting part is a truncated cone structure. The limiting part one is integrally provided at the large diameter end of the connecting part. The connecting ring one is integrally provided at the end of the limiting part one. The inner side of the connecting ring is provided with an internal thread that mates with the end of the flow channel pipe. The flow channel hole is opened at the central axis of the connecting part and the limiting part one, and the flow channel hole passes through the connecting part and the limiting part one.

[0010] Preferably, the sealing head includes a sealing part and a limiting part two. The sealing part is a truncated cone structure, and the limiting part two is integrally provided at the large-diameter end of the sealing part.

[0011] Preferably, the opening end of the mounting hole is threaded with a fastening ring, and the outer end face of the fastening ring has symmetrical positioning holes. Using a two-jaw wrench that matches the positioning holes, the fastening ring can be rotated and tightened. The inner end of the fastening ring presses against the limiting part one on the connector or the limiting part two on the sealing head, so that the connector or sealing head is tightly set in the mounting hole.

[0012] Preferably, a heating sleeve is fitted over the outside of the flow channel tube, and a heating wire is installed inside the heating sleeve to heat the flow channel tube and prevent the molten material from cooling inside the flow channel tube.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The length of the runner tube in this utility model can be changed according to the mold cavity. By changing the runner tube to different lengths, the position of the hot nozzle relative to the main manifold can be adjusted, so that the hot runner system can be used in more molds and has a wider range of applications. The quick-disassembly connector allows for faster disassembly and replacement of the runner tube, making the operation more convenient and efficient. Attached Figure Description

An injection nozzle 3 is located above the main flow channel of the main flow divider 1, and a hot nozzle 8 is located below the secondary flow divider 2.
