Description

Technical Field

[0001] This utility model relates to the field of spinning machinery technology, specifically to a multi-station die-casting device for pressing the palm of a roving frame. Background Technology

[0002] The roving press is a key component on the spindle blade of a roving frame. It is mainly used to guide the roving to the bobbin and apply pressure to the bobbin to make it firm. It is mainly formed by die casting. Currently, the roving press is mainly formed by die casting process. However, traditional die casting equipment has a significant drawback: the next casting operation cannot be carried out before the workpiece inside the mold body is completely cooled. This process is time-consuming and seriously restricts production efficiency. To address this, we propose a multi-station die casting device for the roving frame roving press. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] See attached document Figure 1-3A multi-station die-casting device for a roving frame includes a base 1, a central column 2 on the base 1, the central column 2 being hollow and fixed to the base 1, a worktable 3 rotatable around its axis fitted on the outer wall of the central column 2, several receiving grooves 5 penetrating its body being opened circumferentially on the inner circumference of the worktable 3, and a lower mold 4 rotatably connected in each receiving groove 5, so that the mold cavity at the top of the lower mold 4 can be flipped downwards, a top plate 16 on the top of the central column 2, and a cylinder 17 on the side of the top plate 16 away from the central column 2, with an upper mold 18 corresponding to the lower mold 4 at the bottom output end of the cylinder 17 for mold closing and die casting. Activating the cylinder 17 causes the upper mold 18 to descend and cooperate with the lower mold 4 to complete mold closing. After die casting is completed... The upper mold 18 and lower mold 4 are separated by the cylinder 17. Then, the worktable 3 is rotated so that another lower mold 4 moves to the position of the upper mold 18. The above operation is repeated to control different lower molds 4 to close and die-cast with the upper mold 18 in sequence. After a period of time, the workpiece in the lower mold 4 is cooled down. Then, the lower mold 4 can be flipped so that the workpiece in the lower mold 4 falls down quickly without manual material removal. Moreover, by using multiple lower molds 4, when one lower mold 4 separates from the upper mold 18 for cooling, another lower mold 4 can immediately start die-casting. This allows for material removal and preparation for the next round of die-casting without waiting for the workpiece to cool down completely, ensuring the continuity of die-casting and greatly improving processing efficiency.

[0021] In this embodiment, a rotating shaft 6 is provided on the side of the lower mold 4 facing the axis of the central column 2. A torsion spring 7 is sleeved on the outer wall of the rotating shaft 6. The two ends of the torsion spring 7 are respectively connected to the receiving groove 5 and the lower mold 4 to provide a reset torque for the lower mold 4. A first gear 8 is provided on the outer wall of the rotating shaft 6. A strip groove 9 for receiving the first gear 8 is opened in the worktable 3. A vertical plate 10 is provided on the base 1. A rack 11 that engages with the first gear 8 is provided on the top of the vertical plate 10 to realize the flipping of the lower mold 4. When the worktable 3 drives the lower mold 4 to rotate to the position of the rack 11, the rack 11 limits the first gear 8 and causes it to rotate. At this time, the rotating shaft 6 drives the lower mold 4 to flip, and the workpiece inside the lower mold 4 falls out. There is no need for workers to pick up the material, which greatly saves manpower.

[0022] In this embodiment, the top of the base 1 is provided with a support plate 15 corresponding to the upper mold 18. The top of the support plate 15 abuts against the bottom of the lower mold 4 below the upper mold 18 to support the lower mold 4 at this position, so as to prevent the lower mold 4 from being pressed and flipped when the mold is closed, which would affect the injection molding effect. The top of the support plate 15 is horizontally set, and its two sides are arc-shaped to prevent the lower mold 4 from abutting against the side wall of the support plate 15 when it tilts and rotates with the worktable 3.

[0023] In this embodiment, a motor 12 is provided on the base 1. A second gear 13 is connected to the top output end of the motor 12. A third gear 14 is meshed with the outer wall of the second gear 13. The third gear 14 is sleeved on the outer wall of the central column 2 and rotatably connected to it. The top of the third gear 14 is connected to the bottom of the worktable 3 to drive it to move around the axis of the central column 2. When the motor 12 is started, the second gear 13 drives the third gear 14 to rotate, which further causes the worktable 3 to drive the lower mold 4 to rotate, which facilitates the subsequent mold closing operation of the lower mold 4.
