With the development of technology, some products require multi-color injection molded products, and the demand for multi-color injection molding machines is increasing. At the same time, a multi-color injection molding machine needs to meet the needs of various working conditions. In addition to multi-color injection molding conditions, sometimes a single injection seat needs to be moved to the center position to be used as a single-color injection molding machine, which may involve the movement of multiple injection seats, and the movement and operation of the injection seat are all supplied with liquid through pipelines.

[0003] In the prior art, a liquid supply valve plate is provided on the frame, a hydraulic valve plate is provided on each injection seat, a pipeline is provided between the liquid supply valve plate and each injection valve plate, and oil is transported through the pipeline. In order to facilitate the movement of the injection seat, the pipeline needs to be set as a hose so as not to generate resistance to the displacement of the injection seat; however, the hose is deformed during the movement of the injection seat and is easily scratched on the frame. At the same time, adjacent hoses are also easily entangled with each other. First, the hose is easily worn and needs to be replaced frequently. Second, the overall aesthetic performance is poor. Summary of the invention

[0004] The utility model is made in consideration of the above-mentioned problems. The purpose of the utility model is to provide a pipe routing structure for a multi-color injection molding machine, which can avoid pipe wear and entanglement, and improve service life and aesthetic performance.

[0007] The two ends of the first pipeline are connected to the bracket and the first integrated block respectively, so that the first pipeline is separated from the frame, and the oil supply valve plate is connected to one end of the first pipeline located on the bracket;

[0008] The second pipeline is located above the first pipeline, and the two ends of the second pipeline are respectively connected to the first integrated block and the injection valve plate.

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] like Figure 1-3 As shown, in the present application, the injection molding machine includes a frame 1, a base 2 movably arranged on the frame 1 along a first direction, a plurality of injection seats 3 movably arranged on the base 2 along a second direction, an oil supply valve plate 4 located on the frame 1, and an injection valve plate 5 located on the injection seat 3. Oil supply pipelines are provided between the oil supply valve plate 4 and the plurality of injection valve plates 5. In the present embodiment, the first direction is the width direction of the frame 1, i.e., the front-to-back direction, and the second direction is the length direction of the frame 1, i.e., the left-to-right direction. When the base 2 moves along the front-to-back direction, the plurality of injection seats 3 can be driven to move together, and the relative positions of the two will not change. When the injection seat 3 moves along the left-to-right direction, it will generate relative movement with the base 2. The oil supply valve plate 4 supplies oil to the injection valve plate 5 through the oil supply pipeline to provide the energy required for the injection seat 3 to work, and the oil supply pipeline is divided into a first pipeline 6 and a second pipeline 7 for separate control.

[0025] In this embodiment, a pipe routing structure of a multi-color injection molding machine includes a bracket 8, a first integrated block 9 and a support plate 10. The bracket 8 is fixed on the frame 1. The first integrated block 9 and the support plate 10 are both fixed on the base 2. The first integrated block 9 is used to connect the first pipeline 6 and the second pipeline 7. The support plate 10 is used to provide support for the second pipeline 7. The two ends of the first pipeline 6 are respectively connected to the bracket 8 and the first integrated block 9 to separate the first pipeline 6 from the frame 1. The oil supply valve plate 4 is connected to one end of the first pipeline 6 located on the bracket 8. The second pipeline 7 is located above the first pipeline 6, and the two ends of the second pipeline 7 are respectively connected to the first integrated block 9 and the injection valve plate 5. The support plate 10 is located between the first pipeline 6 and the second pipeline 7. When the injection seat 3 moves along the second direction, the support plate 10 can abut against the bottom of the second pipe 7 to support the second pipe 7. After the first pipe 6 is separated from the frame 1 by the bracket 8 and the first integrated block 9, when the injection seat 3 moves along the second direction, the position of the first pipe 6 remains unchanged. Only when the base 2 moves along the first direction will the first pipe 6 swing back and forth. However, since it is separated from the surface of the frame 1, the first pipe 6 will not be worn. During this process, the second pipe 7 maintains a relative position and does not move. Only when the injection seat 3 moves along the second direction will it drive the second pipe 7 to move in the left and right directions, causing the second pipe 7 to sag. The support plate 10 can prevent the second pipe 7 from sagging and entangled with the first pipe 6.

[0026] In order to realize the movement of the base 2 and the injection seat 3, a first guide rail arranged along the width direction of the frame 1 is provided on the frame 1, the base 2 is movably set on the first guide rail, and the top of the base 2 is provided with a second guide rail arranged along the length direction of the frame 1, and multiple injection seats 3 can be movably set on the second guide rail, that is, the base 2 can be displaced along the first guide rail, and the injection seat 3 can be displaced along the second guide rail.

[0027] In order to ensure the stability of the connection between the first pipe 6 and the second pipe 7, the bracket 8 and the base 2 are arranged on the top of the frame 1 along the length direction of the frame 1. When the base 2 moves along the width direction of the frame 1, the first pipe 6 will only swing along the width direction to avoid scratching the upper surface of the frame 1. The first pipe 6 is L-shaped as a whole, and the first pipe 6 includes a first hose 12 and two first hard pipes 11 located at both ends of the first hose 12, one of the first hard pipes 11 is inserted from bottom to top into the top of the bracket 8, and the other first hard pipe 11 is inserted from top to bottom. Into the first integrated block 9, two first hard tubes 11 are used for insertion and positioning, and the two first hard tubes 11 are also used to position the first hose 12 to prevent it from sagging; at the same time, the second pipeline 7 is in an arc shape as a whole, and the second pipeline 7 includes a second hose 14 and two second hard tubes 13 located at both ends of the second hose 14, one of the second hard tubes 13 can be inserted into the injection valve plate 5, and the other second hard tube 13 can be inserted into the first integrated block 9, and the two second hard tubes 13 are used for insertion and positioning, and rigid positioning is also provided for the second hose 14.

[0028] In order to achieve the connection between the oil supply valve plate 4 and the first pipeline 6, a second integrated block 15 is also included. The second integrated block 15 is installed on the top of the bracket 8, and one of the first hard pipes 11 can be inserted into the second integrated block 15. The oil supply valve plate 4 is connected with the second integrated block 15 through a third pipeline, that is, the oil supply valve plate 4 transports the hydraulic oil to the second integrated block 15 through the third pipeline, and then transmits it to the first pipeline 6 through the oil channel in the second integrated block 15.

[0029] In order to prevent the second pipe 7 from excessively wearing on the support plate 10 , the upper surface of the support plate 10 is configured as a smooth surface, which can reduce the wear on the second pipe 7 .
