Abstract
Description
Technical Field
[0001] The utility model relates to an injection mold industry, in particular to a gate sleeve with a split fine water gate structure. Background Art
[0002] High-precision injection molds are important tools in modern manufacturing, and their manufacturing quality and efficiency have a vital impact on product quality and production efficiency. In injection molds, the sprue bushing is one of the key components for controlling the injection of materials into the mold. Traditional sprue bushing designs often ignore the problems of processing difficulty and assembly accuracy, resulting in long processing time and difficulty in ensuring accuracy, while also affecting the overall performance of the injection mold. Specifically, the inner runner part of the traditional sprue bushing usually adopts an integral design, which makes the gate channel relatively long, resulting in long and difficult electrode processing time, and is prone to carbon deposits and roughness problems, further leading to a decline in casting quality. Utility Model Content
[0003] In view of the above situation, it is necessary to provide a sprue bushing with a split fine water gate structure that solves at least one of the above problems, characterized in that it includes:
[0004] A first pouring member, comprising a first column, one end of which is provided with a groove opening, and an interior of the first column is provided with a first pouring channel that penetrates therethrough;
[0005] and a second pouring member, comprising a second column, one end of which is provided with a protrusion, and the interior of which is provided with a penetrating second pouring channel;
[0006] Wherein, the protrusion matches the groove, and when the groove fits with the protrusion, the first pouring channel is connected with the second pouring channel.
[0007] Preferably, it also includes a limiting structure for limiting the protrusion and the groove.
[0008] Preferably, the limiting structure includes a convex opening and a concave opening, the convex opening is arranged on both sides of the convex opening, and the concave opening is arranged on both sides of the concave opening, wherein when the concave opening fits with the convex opening, the convex opening is clamped in the concave opening.
[0009] Preferably, the channel volume gradually decreases from the first pouring channel along the direction of the second pouring channel.
[0010] Preferably, a clamping structure is provided at the other end of the first column for fixing the first gate member.
[0011] The gate sleeve is composed of a first gate piece and a second gate piece. The inner flow channel of the gate sleeve can only be processed by EDM discharge. The longer the length, the more difficult the electrode processing. The discharge time is long. By adopting a segmented type, the distance of its internal channel becomes smaller, the processing accuracy is improved and the processing difficulty is reduced, making the electrode processing convenient and simple, shortening the EDM processing time and avoiding carbon deposition and roughness problems. At the same time, the second gate piece can be made into a standard part to facilitate the replacement of the damaged gate in mass production of the mold. The first gate piece is processed by NC wire walking, with short processing time, high precision and easy polishing. The state is stable after the test. At the same time, a convex mouth and a groove mouth are provided. When the first gate piece and the second gate piece are combined, the convex mouth and the groove mouth fit together, which improves the combination accuracy of the first gate piece and the second gate piece, and then improves the connection accuracy of the first pouring channel and the second pouring channel.

[0022] See also Figures 1 to 6 The gate sleeve with a split fine water gate structure of the embodiment of the utility model is characterized in that it includes a first gate member 1, including a first column 11, one end of which is provided with a groove opening 12, and the interior of the first column 11 is provided with a through first pouring channel 13; and a second gate member 2, including a second column 21, one end of which is provided with a protrusion 22, and the interior of the second column 21 is provided with a through second pouring channel 23; wherein the protrusion 22 matches the groove opening 12, and when the groove opening 12 is matched with the protrusion 22, the first pouring channel 13 is connected with the second pouring channel 23.
[0023] In the above embodiment, in the high-precision injection molds used for various types of high-precision fine-gate structures, the gate sleeve is composed of the first gate piece 1 and the second gate piece 2. The inner flow channel of the gate sleeve can only be processed by EDM discharge. The longer the length, the more difficult the electrode processing. The discharge time is long. By adopting a segmented type, the distance of its internal channel becomes smaller, the processing accuracy is improved and the processing difficulty is reduced, the electrode processing is convenient and simple, the EDM processing time can be shortened and the carbon deposition and roughness problems can be avoided. At the same time, the second gate piece 2 can be made into a standard part to facilitate the replacement of the gate damage in mass production of the mold. The first gate piece 1 is processed by NC wire walking, with short processing time, high precision and easy polishing. The state is stable after the test. At the same time, a convex mouth 22 and a groove mouth 12 are provided. When the first gate piece 1 and the second gate piece 2 are combined, the convex mouth 22 and the groove mouth 12 fit together, which improves the combination accuracy of the first gate piece 1 and the second gate piece 2, and then improves the connection accuracy of the first pouring channel 13 and the second pouring channel 23.
[0024] See also Figures 1 to 6 In another embodiment, a limiting structure 3 is further included to limit the protrusion 22 and the groove 12.
[0025] In the above embodiment, the limiting structure 3 serves to ensure that the first gate member 1 and the second gate member 2 will not be accidentally separated due to external force or other factors when connected, thereby ensuring the continuity and stability of the casting process.
[0026] See also Figures 1 to 6 In another embodiment, the limiting structure 3 includes a convex opening 31 and a groove opening 32, the convex opening 31 is arranged on both sides of the convex opening 22, and the groove opening 32 is arranged on both sides of the groove opening 12, wherein when the groove opening 12 is matched with the convex opening 22, the convex opening 31 is clamped in the groove opening 12.
[0027] In the above embodiment, the convex opening 31 is arranged on both sides of the convex opening 22, and its main function is to provide additional support and stability to ensure that the convex opening 22 will not be easily separated when connected to the groove opening 12. The design of the groove position 32 and the convex opening 31 can prevent accidental separation caused by external force or other factors, further improving the reliability and stability of the system. It is arranged on both sides of the groove opening 12, and is designed to match the convex opening 31. When the convex opening 22 fits with the groove opening 12, the groove position 32 and the convex opening 31 are mutually engaged to form a stable connection structure. It can ensure a tight connection between the convex opening 22 and the groove opening 12, thereby optimizing the flow of the casting material and improving the efficiency and accuracy of the casting process. At the same time, due to its simple structure and reasonable design, the entire system is more durable and reliable.
[0028] See also Figures 1 to 6In another embodiment, the channel volume from the first pouring channel 13 along the direction of the second pouring channel 23 gradually decreases.
[0029] In the above embodiment, firstly, the gradual reduction of the channel volume can ensure that the casting material gradually slows down during the flow process, thereby reducing material impact and turbulence and making the flow smoother. Secondly, it is more difficult for the casting material to flow back or reflux, thereby ensuring the continuity and accuracy of the casting process. As the channel gradually becomes smaller, the flow rate of the casting material can be gradually reduced, thereby reducing pressure loss and making the casting process more efficient. Finally, by controlling the flow rate and direction of the casting material, this design also helps to optimize the quality and consistency of the cast product. In summary, the design of the gradually decreasing channel volume from the first pouring channel 13 along the direction of the second pouring channel 23 helps to improve the efficiency of the casting process and the quality of the product by providing a more stable flow of casting material.
[0030] See also Figures 1 to 6 In another embodiment, a clamping structure 4 is provided at the other end of the first column 11 for fixing the first gate member 1 .
[0031] In the above embodiment, the first gate member 1 can be more firmly fixed on the casting equipment through the clamping structure 4, thereby reducing the risk of displacement due to vibration or external force.
[0032] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
