Problems solved by technology

[0002] The pipeline above the hot runner wire rack is currently clamped and fixed by a method similar to a U-shaped clamp. However, the pipeline is generally made of a polytetrafluoroethylene tube wrapped with a stainless steel reinforcement layer or a Teflon tube, which has a certain The rigidity is not as easy to bend as a hose
Therefore, when this kind of U-shaped clamp is under full load, because its fixing screw is under the pipeline, when the pipeline is damaged and the U-shaped clamp needs to be replaced, it is almost impossible to disassemble or use destructive removal methods. Inconvenience in after-sales maintenance
At the same time, although the external size of this structure is relatively large, the actually available internal flow area is relatively small. As a result, even when a small number of pipelines pass through, a large-sized clamp is still required, which also increases the cost to a certain extent. ; More importantly, it caused obvious wear to the clamping part of the pipeline
[0003] The existing U-shaped clamp is because its fixing screw is under the pipeline, and the pipeline is a stainless steel reinforced layer pipeline with a polytetrafluoroethylene tube, which has a certain rigidity and is not as easy to bend as a hose. Therefore, when the U-shaped clamp is fully loaded, if you want to disassemble the U-shaped clamp or replace a certain pipeline at the bottom, it is almost impossible to disassemble or use destructive removal methods
This greatly reduces the convenience of after-sales maintenance
In addition, due to the structural factors, the internal space utilization rate is low, that is, although the external size is large, the actual internal flow area is small, resulting in the need to use a larger pipe when passing through. U-clip
[0004] CN204664622U discloses a new type of pipeline L-shaped clamp, which has more flexible detachability and has a larger effective flow cross-sectional area, but still involves long-term use of worn pipelines and shortens the service life of the pipelines

Embodiment 1

[0028] The embodiment of the invention discloses a pipe clamp for hot runner system, such as figure 1 and figure 2 As shown, a clamping ring 1 is included which has a circular cross-section and which forms a point contact between the clamping ring 1 and the tubing 2 clamped in the clamping ring 1 to bear against the tubing 2 . The number of clamped pipelines 2 can be one or multiple. In this embodiment, the pipelines 2 are made of Teflon tubes, or can be made of carbon steel; when the pipelines 2 run through When the ring inner space of the clamping ring 1 abuts against the inner wall of the clamping ring 1, since the arc-shaped ring inner wall of the clamping ring 1 cross-contacts with the arc-shaped outer wall of the pipeline 2, the contact parts are two arcs The tangent point of the wall surface; in specific implementation, the section of the clamping ring 1 can also be a semicircular section, and the arc-shaped outer surface of the clamping ring 1 is used as the inner wa...

Embodiment 2

[0038] The embodiment of the present invention also discloses a hot runner system, including a manifold, a drive device and a main nozzle located at the upper end of the manifold, and a hot nozzle located at a position corresponding to the drive device at the lower end of the manifold, and a connection between the drive device and the nozzle The valve needle, the valve needle is fixedly connected to the lower surface of the piston of the driving device, and also includes the wire rack fixed on the manifold. The hot runner system also includes the above-mentioned pipe clamp, which is fixed on the wire rack; the number of pipe clamps is as many as , distributed at intervals along the pipeline extension direction on the wire rack.

[0039] Such as figure 1 and figure 2 As shown, the pipe clamp comprises a clamping ring 1 having a circular cross-section, and a point contact is formed between the clamping ring 1 and the pipeline 2 clamped in the clamping ring 1 to bear against th...

Abstract

The invention provides a pipeline clamp for a hot runner system. The pipeline clamp comprises a clamping ring, the clamping ring has a circular or semi-circular section, and point contact is formed between the clamping ring and pipelines clamped in the clamping ring, so that the clamping ring abuts against the pipelines. The invention further provides a hot runner system comprising the pipeline clamp. According to the pipeline clamp, the pipelines on a thread stand can be steadily clamped, wear of the pipeline clamp to the pipelines due to clamping can be reduced through the point contact clamping structure, the service life of the pipelines is prolonged, and meanwhile the pipeline clamp has the advantages of being simple and compact in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of hot runners, and relates to a pipe clamp used in a hot runner system and a hot runner system with the same. Background technique [0002] The pipeline above the hot runner wire rack is currently clamped and fixed by a method similar to a U-shaped clamp. However, the pipeline is generally made of a polytetrafluoroethylene tube wrapped with a stainless steel reinforcement layer or a Teflon tube, which has a certain The rigidity of the hose is not as easy to bend as the hose. Therefore, when this kind of U-shaped clamp is under full load, because its fixing screw is under the pipeline, when the pipeline is damaged and the U-shaped clamp needs to be replaced, it is almost impossible to disassemble or use destructive removal methods. Inconvenience in after-sales maintenance. At the same time, although the external size of this structure is relatively large, the actually available internal flow area is relati...
