Description

Technical Field

[0001] This utility model relates to the field of coolant circuit technology, specifically to the coolant circuit system of a worm gear injection mold. Background Technology

[0002] The coolant channels in existing worm gear injection molds are mostly straight channels in one direction, which can only cool a local area of ​​the mold. The cooling coverage is limited, and the channel layout lacks symmetrical design, resulting in uneven temperature distribution in the worm gear molding area. This easily leads to defects such as deformation, shrinkage marks, and warping of the injection molded parts, which seriously affects the molding accuracy of the product. Utility Model Content

[0003] The purpose of this invention is to provide a cooling fluid system for worm gear injection molds to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cooling fluid system for a worm gear injection mold, comprising a base block, a feed block, a central liquid cooling flow path, and two side liquid cooling flow paths; The central liquid cooling flow path is installed in the central cavity of the base block, and the central liquid cooling flow path includes a horizontal main pipe and a vertical branch pipe that are perpendicularly connected to each other, as well as a connector. The two side liquid cooling flow paths are symmetrically distributed on both sides of the central liquid cooling flow path. The side liquid cooling flow path includes an L-shaped deflector, a straight branch pipe and a vertical branch pipe. The side liquid cooling flow path is embedded in the inner cavity of the feed block.

[0005] The beneficial effects of adopting the above technical solution are as follows: the central liquid cooling flow path passes through the central inner cavity of the base block, and the two side liquid cooling flow paths are symmetrically distributed on both sides of the central liquid cooling flow path and embedded in the inner cavity of the feed block. Through the split layout of the "base block-feed block" and the symmetrical design of the flow channels, a surrounding cooling is formed for the injection molding area of ​​the worm gear. The horizontal main pipe and vertical branch pipe of the central liquid cooling flow path work together with the L-shaped turning joint, straight branch pipe and vertical branch pipe of the side liquid cooling flow path to greatly expand the cooling coverage area and effectively avoid the problem of uneven local cooling of the injection molded parts. At the same time, the connector provides a convenient interface for the connection between the central liquid cooling flow path and the external pipeline, simplifying the assembly process.

[0006] As a further improvement of this utility model, the transverse main pipe extends along the length direction of the feed block, the vertical branch pipe extends along the height direction of the feed block, and the upper end of the vertical branch pipe is integrally formed and connected to the middle part of the transverse main pipe, and one end of the transverse main pipe is connected to the connector.

[0007] The beneficial effects of adopting the above technical solution are as follows: the horizontal main pipe extends along the length of the feed block, and the vertical branch pipe extends along the height of the feed block and is integrally formed and connected with the middle of the horizontal main pipe. The integrally formed structure not only enhances the structural strength and sealing performance of the connection between the horizontal main pipe and the vertical branch pipe, preventing coolant leakage, but also allows the coolant to flow smoothly in the flow channel, reducing flow resistance. The connection design between the horizontal main pipe and the connector further improves the stability and convenience of docking the central liquid cooling flow path with the external coolant supply device.

[0008] As a further improvement of this utility model, one end of the L-shaped steering joint is fixedly connected to one end of the straight branch pipe, and the other side of the L-shaped steering joint is embedded in the inner wall of the feed block.

[0009] The beneficial effects of adopting the above technical solution are as follows: one end of the L-shaped diverter is fixedly connected to the straight branch pipe, and the other side is embedded in the inner wall of the feed block. This double fixing structure not only realizes the stable assembly of the side liquid cooling flow path and the feed block, preventing the flow channel from shifting due to vibration during mold operation, but also allows for flexible adjustment of the direction of the straight branch pipe through the L-shaped diverter, accurately adapting to the internal space layout of the feed block, ensuring a compact and reasonable flow channel arrangement, and improving the overall structural stability of the side liquid cooling flow path.

[0010] As a further improvement of this utility model, the number of the straight branch pipes is two, the two straight branch pipes are arranged in parallel, and both are connected to the vertical branch pipe.

[0011] The advantages of adopting the above technical solution are: the two straight branch pipes are arranged in parallel and are both connected to the vertical branch pipe, forming a parallel structure of the side cooling branch. The coolant flow rate of a single straight branch pipe can be flexibly adjusted according to the process requirements of worm gear injection molding, so as to achieve targeted cooling of specific areas of the mold and improve the cooling accuracy. At the same time, the parallel structure makes it easy to disassemble and maintain a single straight branch pipe without disassembling the entire side liquid cooling flow path, reducing maintenance costs and downtime.

[0012] As a further improvement of this utility model, the diameter of the transverse main pipe is larger than the diameter of the straight branch pipe, and the wall thickness of the transverse main pipe is the same as the wall thickness of the straight branch pipe.

[0013] The beneficial effects of adopting the above technical solution are as follows: the diameter of the horizontal main pipe is larger than that of the straight branch pipe, and the wall thickness of the two is the same. This design not only ensures the coolant delivery volume of the horizontal main pipe as the main channel to meet the overall cooling needs of the mold, but also improves the local cooling accuracy through the small diameter design of the straight branch pipe, adapting to the fine cooling needs of local areas of the mold; the same wall thickness ensures that the overall structural strength of the flow channel is consistent, avoiding stress concentration caused by thickness differences and extending the service life of the flow channel.

[0014] As a further improvement of this utility model, a rubber buffer layer is provided on the inner wall of the central cavity of the base block, and the rubber buffer layer is attached to the outer wall of the transverse main pipe of the central liquid cooling flow path.

[0015] The beneficial effects of adopting the above technical solution are as follows: the rubber buffer layer on the inner wall of the central cavity of the base block is attached to the outer wall of the transverse main pipe. The rubber buffer layer can effectively absorb the impact of the vibration generated during the operation of the mold on the transverse main pipe, reduce the wear at the connection between the transverse main pipe and the vertical branch pipe and the connector, and improve the structural stability and service life of the central liquid cooling flow path. At the same time, the fitting design of the rubber buffer layer enhances the sealing performance between the transverse main pipe and the base block, further preventing coolant leakage and improving the working reliability of the liquid cooling system.

[0016] As a further improvement of this utility model, there are two horizontal main pipes and two vertical branch pipes, and the two horizontal main pipes and two vertical branch pipes are distributed in a square shape.

[0017] The beneficial effects of adopting the above technical solution are as follows: the two horizontal main pipes and two vertical branch pipes are distributed in a U-shape. This layout greatly expands the cooling coverage area of ​​the central liquid cooling flow path, allowing the coolant to flow evenly through the core molding area of ​​the mold, effectively reducing defects such as deformation and shrinkage marks caused by uneven cooling in worm gear injection molded parts, and improving product molding accuracy; at the same time, the U-shaped flow channel structure makes the coolant flow more even, further improving heat exchange efficiency and shortening the cooling molding cycle.
