Description

Technical Field

[0001] This utility model relates to the field of metal die casting technology, and in particular to a flow divider cone. Background Technology

[0002] In metal die casting production, the manifold cone is a key component for guiding molten metal. Currently, with traditional manifold cones, the sprue must be ejected under high pressure from the punch during mold opening. This forced ejection method easily leads to the sprue breaking or deforming, directly causing product scrap and production interruption. Furthermore, maintaining high-pressure ejection consumes a large amount of energy, significantly increasing the operating cost of the die casting machine. In addition, because the sprue is not firmly positioned on the manifold cone, it is also at risk of breaking during mold opening, further affecting the stability and continuity of production. Existing manifold cone technology has become a bottleneck restricting the improvement of production efficiency and the achievement of energy conservation and consumption reduction. Therefore, there is an urgent need for a new type of manifold cone device to solve the problems of difficult sprue ejection, high energy consumption, and poor production stability. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a flow divider cone that eliminates the need for high-pressure ejection, thereby improving the stability and efficiency of material discharge.

[0004] A flow divider cone according to an embodiment of the present invention includes: The body has a boss, a guide groove on one side of the boss, and a recessed fastening groove on the end wall of the boss. One end of the fastening groove is connected to the guide groove. When the material handle is formed, the fastening groove enables the material handle to form a fastener. The fastener is embedded in the fastening groove. The fastening groove has a first wall surface and a second wall surface. Both the first wall surface and the second wall surface are inclined to the end wall of the boss, and the first wall surface and the second wall surface can abut against the side wall of the fastener.

[0005] A flow divider cone according to an embodiment of the present utility model has at least the following beneficial effects: This embodiment includes a main body with a boss. A guide groove is provided on one side of the boss, and a recessed fastening groove is provided on the end wall of the boss. One end of the fastening groove is connected to the guide groove. When the material handle is formed, the fastening groove enables the material handle to form a fastener. The fastener is embedded in the fastening groove. The fastening groove has a first wall surface and a second wall surface. Both the first wall surface and the second wall surface are inclined to the end wall of the boss, and the first wall surface and the second wall surface can abut against the side wall of the fastener, thereby enabling the fastener to fasten with the fastening groove and connecting the material handle to the main body of the flow divider cone. When the mold is opened, the material handle is pulled, eliminating the need for a punch to eject it, thus avoiding damage to the material handle, improving the stability and efficiency of material output, and saving energy.

[0006] According to some embodiments of this utility model, the width of one end of the fastening groove that connects to the guide groove is greater than the width of the other end. When the material handle moves toward the guide groove, the fastener can disengage from the fastening groove, making it easy for the material handle to come off the body.

[0007] According to some embodiments of this utility model, the direction parallel to the end wall of the boss and towards the guide groove is defined as the first direction, and the angle between the first wall surface and the second wall surface along the first direction is α, which satisfies: 15°≤α≤25°.

[0008] According to some embodiments of this utility model, the fastening groove is provided with a third wall surface, which is inclined to the end wall of the boss, thereby improving the stability of the fastening between the body and the material handle.

[0009] According to some embodiments of the present invention, the angle between the first wall surface, the second wall surface, and the third wall surface and the end wall of the boss is β, which satisfies: 65°≤β≤75°.

[0010] According to some embodiments of this utility model, the third wall surface is an arc surface, and the two ends of the third wall surface are respectively connected to the first wall surface and the second wall surface, making the fastener easy to form and avoiding stress concentration.

[0011] According to some embodiments of the present invention, the fastener is provided with a first mating surface and a second mating surface. The first mating surface abuts against the first wall surface, and the second mating surface abuts against the second wall surface, thereby realizing the fastening of the fastener and the fastening groove.

[0012] According to some embodiments of the present invention, the bottom wall of the fastening groove is inclined and moves towards the direction of the guide groove. The bottom wall of the fastening groove is inclined away from the end wall of the boss, which is beneficial to improving the flow efficiency of the molten metal and making it easier for the fastener to come out of the fastening groove.

[0013] According to some embodiments of this utility model, transition surfaces are provided on both sides of the part where the fastening groove and the guide groove are connected. The transition surfaces are arc-shaped, which is beneficial to improving the flow efficiency of the molten metal and can avoid stress concentration during fastener forming.

[0014] According to some embodiments of this utility model, the maximum depth of the snap-fit ​​groove is less than 1 / 4 of the maximum width of the snap-fit ​​groove, which can reduce the contact area between the fastener and the snap-fit ​​groove, thereby reducing the resistance when the material handle comes out of the body.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0022] Reference Figure 1 A flow divider cone according to an embodiment of the present invention includes a body 100, the body 100 having a boss 101, and a flow guide groove 102 on one side of the boss 101. The flow guide groove 102 is used to guide the molten metal to flow into the mold cavity during the die casting process, ensuring a smooth and uniform filling process. The end wall of the boss 101 has a recessed snap-fit ​​groove 103, one end of which communicates with the flow guide groove 102. When the material handle 120 is formed, the snap-fit ​​groove 103 enables the material handle 120 to form a fastener 121. The fastener 121 is embedded in the snap-fit ​​groove 103. The snap-fit ​​groove 103 is provided with a first wall surface 104 and a second wall surface 105. The first wall surface 104 and the second wall surface 105 are both inclined to the end wall of the boss 101, and the first wall surface 104 and the second wall surface 105 can abut against the side wall of the fastener 121, so that the fastener 121 is snapped into the snap-fit ​​groove 103, and the material handle 120 is connected to the body 100 of the flow divider cone. When the mold is opened, the material handle 120 is pulled, and there is no need to use a punch to eject it, so as to avoid damage to the material handle 120, improve the stability and efficiency of material output, and save energy.

[0023] Understandably, when the molten metal fills the cavity and cools to form the mold, a portion of the molten metal will flow into and fill the snap-fit ​​groove 103, thereby forming a complementary, protruding snap fastener 121 at the corresponding position on the stalk 120. This formed snap fastener 121 will be completely embedded in the snap-fit ​​groove 103, so that a mechanically interlocking snap-fit ​​relationship is formed between the stalk 120 and the body 100 of the flow divider cone.

[0024] Understandably, both the first wall surface 104 and the second wall surface 105 are inclined to the end wall of the boss 101. After the stalk 120 is formed, the fastener 121 on it has side walls corresponding to the first wall surface 104 and the second wall surface 105. When the mold opening action begins, the flow divider cone body 100 separates from the mold and moves. At this time, the first wall surface 104 and the second wall surface 105 of the fastening groove 103 will respectively abut against and act on the corresponding side walls of the fastener 121, thereby providing sufficient friction and mechanical constraint force to the fastener 121, ensuring that under the action of the mold opening force, the stalk 120 can be firmly pulled on the flow divider cone body 100 and then ejected from the fixed mold together, completely eliminating the dependence on the high-pressure ejection of the punch.

[0025] Understandably, the width of the end of the snap-fit ​​groove 103 that connects to the flow guide groove 102 is greater than the width of the other end, forming a trapezoidal open structure. When it is necessary to remove the material handle 120 from the flow divider cone, the material handle 120 will move along the direction close to the flow guide groove 102. Since the snap-fit ​​groove 103 gradually widens in this direction, it provides more space for the fastener 121 to detach, allowing the fastener 121 to slide smoothly out of the snap-fit ​​groove 103, thereby allowing the material handle 120 to easily separate from the body 100 and avoiding secondary damage.

[0026] Reference Figure 2 In this embodiment, the direction parallel to the end wall of the boss 101 and towards the guide groove 102 is defined as the first direction. The angle between the first wall surface 104 and the second wall surface 105 along this first direction is defined as α, and the angle α satisfies: 15°≤α≤25°. It can be understood that if the angle α is less than 15°, the first wall surface 104 and the second wall surface 105 will be too close to parallel, which will cause the fastener 121 to be too tightly engaged with the fastening groove 103 during mold opening, increasing the demolding resistance and making it easy for the fastener 121 to be sheared and broken during forced pull-out, thus failing to achieve smooth demolding. If the angle α is greater than 25°, the fastening groove 103 will become too open and shallow. During mold opening, the containment and mechanical constraint force of the wall surface of the fastening groove 103 on the fastener 121 will be significantly weakened, and it will not be able to provide sufficient fastening force. The stalk 120 may detach from the flow divider cone prematurely due to its own weight or slight resistance, failing to be reliably pulled out of the mold, leading to stalk breakage and production interruption. Therefore, controlling the included angle α between 15° and 25° ensures both a stable and reliable latching force during mold opening and maintains a suitable opening angle so that the stalk can be stably pulled out.

[0027] In some embodiments, the fastening groove 103 is further provided with a third wall surface 106. This third wall surface 106 is also inclined to the end wall of the boss 101, which further increases the contact area and constraint direction between the fastening groove 103 and the fastener 121. When the fastener 121 is inserted, its end will contact the third wall surface 106, which makes the material handle 120 stable when subjected to forces in multiple directions, thereby improving the stability and reliability of the fastening between the body 100 and the material handle 120, and effectively preventing the material handle 120 from shaking or loosening under complex stress conditions.

[0028] Reference Figure 3 and Figure 4The included angles between the first wall surface 104, the second wall surface 105, and the third wall surface 106 and the end wall of the boss 101 are defined as β. This included angle β satisfies: 65° ≤ β ≤ 75°. It is understandable that if the included angle β is less than 65°, meaning the walls of the fastening groove 103 are too gentle relative to the end wall, the resulting fastener 121 will be too short and thin, lacking sufficient mechanical strength. Under the force of mold opening, the fragile base of the fastener 121 is prone to breakage, leading to fastening failure. Simultaneously, the gentle walls result in insufficient radial constraint force of the fastening groove 103 on the fastener 121, potentially causing the shank 120 to wobble or even loosen within the mold, compromising the stability of the demolding process. If the included angle β is greater than 75°, the wall of the snap-fit ​​groove 103 will be almost perpendicular to the end wall. During demolding, the connection stability between the fastener 121 and the side wall of the snap-fit ​​groove 103 will be insufficient, and the fastener 121 will easily detach from the snap-fit ​​groove 103, causing the material handle 120 to be unable to exit smoothly. Therefore, setting the included angle β between 65° and 75° can ensure that the snap-fit ​​groove 103 has sufficient depth and inclination to form a complete fastener 121, thereby providing strong snap-fit ​​strength and constraint force, and ensuring the stability of the mold opening action.

[0029] Furthermore, the third wall surface 106 can be designed as a smooth arc surface. Both ends of this arc surface are smoothly connected to the first wall surface 104 and the second wall surface 105, respectively. This improves the flow state during molten metal filling, avoids turbulence or air entrapment caused by sharp corners, and ensures the tightness of the fastener 121. Simultaneously, in terms of stress, the rounded corners effectively eliminate stress concentration, preventing the fastener 121 from cracking due to stress concentration during molding or demolding. It also extends the service life of the flow divider cone body 100 mold and avoids fatigue cracks starting from sharp corners.

[0030] Reference Figures 5 to 7 It is understandable that the fastener 121 formed on the material handle 120 also has corresponding mating surfaces. Specifically, the fastener 121 has a first mating surface 122 and a second mating surface 123. When the fastener 121 is inserted into the fastening groove 103, the first mating surface 122 abuts tightly against the first wall surface 104 of the fastening groove 103, and the second mating surface 123 abuts tightly against the second wall surface 105, ensuring the uniform transmission of the fastening force and achieving a stable and reliable mechanical fastening. At the same time, the fastening groove 103 has a third wall surface 106, and the fastener 121 correspondingly has a third mating surface 124 that mates with the third wall surface 106.

[0031] Understandably, the bottom wall of the snap-fit ​​groove 103 is inclined. Approaching the flow channel 102, the bottom wall of the snap-fit ​​groove 103 slopes away from the end wall of the boss 101. This inclined structure acts as a guide during molten metal filling, facilitating smoother flow of the molten metal from the snap-fit ​​groove 103 into the flow channel 102 and reducing filling defects. During the demolding stage, this inclined bottom wall provides a natural ejection ramp for the fastener 121. As the spool 120 moves towards the flow channel 102, the fastener 121 can quickly disengage from the bottom wall of the snap-fit ​​groove 103, thereby reducing demolding resistance.

[0032] At the junction of the snap-fit ​​groove 103 and the guide groove 102, transition surfaces 107 are designed on both sides. These transition surfaces 107 are designed as arc-shaped surfaces. The arc-shaped transition surfaces 107 can optimize the flow path of the molten metal, making the flow of the molten metal from the guide groove 102 into the snap-fit ​​groove 103 more stable, avoiding the generation of eddies or dead zones, thereby ensuring the forming quality of the fastener 121. Secondly, the smooth transition can effectively avoid the formation of sharp inner corners at the corresponding positions of the fastener 121, eliminating potential stress concentration points, which improves its structural integrity and reliability both during the ejection process of the shank 120 and in the subsequent use of the product.

[0033] Furthermore, the maximum depth of the snap-fit ​​groove 103 is designed to be less than one-quarter of its maximum width, which controls the embedding depth of the fastener 121. While a deeper snap-fit ​​provides greater snap-fit ​​force, it also results in an excessively large contact area, causing the stalk 120 to overcome greater friction when finally disengaging from the flow divider cone, which can easily damage the stalk. By controlling the depth to be less than one-quarter of the width, the contact area between the fastener 121 and the snap-fit ​​groove 103 can be minimized while ensuring sufficient snap-fit ​​force to prevent loosening during mold opening. This significantly reduces the resistance that the stalk 120 needs to overcome when finally disengaging from the body 100.

[0034] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
