Description

Technical Field

[0001] The utility model belongs to the technical field of hot top casting molds, and particularly relates to a hot top casting mold for aluminum alloy rods. Background Art

[0002] Hot top casting refers to a process of semi-continuous casting of aluminum alloy ingots using a mold with a heat insulation layer installed on the upper part. This casting process usually installs a liquid storage tank made of refractory and heat-insulating materials on the upper part of the mold for semi-continuous casting of aluminum alloy ingots or evenly lines a heat insulation area made of flexible heat-insulating materials on the inner surface of the upper part of a common mold. Its function is to keep the melt at a relatively high temperature when it enters the mold part through the funnel.

[0003] In order to improve the efficiency of hot top casting of aluminum alloy rods, existing hot top casting molds for aluminum alloy rods can form multiple aluminum alloy rods in one casting. Most of these aluminum alloy rods are ejected at one time by a blanking mechanism. When taking some heavier aluminum alloy rods, hoisting equipment is needed for hoisting. Since the distance between the ejected aluminum alloy rods is small, the aluminum alloys are prone to collide with each other during hoisting, resulting in damage and affecting the quality of the formed aluminum alloy rods.

[0004] Therefore, a hot top casting mold for aluminum alloy rods is proposed. Content of the Utility Model

[0022] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0023] An embodiment of the present utility model provides a hot top casting die for aluminum alloy rods, as Figures 1-5As shown in the figure, it includes a lower die 1, an upper die 2 is arranged on the top of the lower die 1, a heat-insulating hot top seat 3 is fixedly connected by bolts at the central position of the top of the upper die 2, an aluminum alloy casting sleeve 4 is arranged at the inner bottom of the lower die 1, a sealing ring groove 5 and a knockout hole 6 are formed at the inner bottom of the lower die 1 near the inner side of the aluminum alloy casting sleeve 4, the sealing ring groove 5 is located above the knockout hole 6, a base 8 is arranged below the lower die 1, support columns 7 are fixedly connected by bolts between the base 8 and the lower die 1, and a first motor 9 is fixedly connected by bolts at the central position of the outer wall of one side of the base 8. The first motor 9 is fixedly connected with a first ball screw 10 through the output end on its one side. The nut seat on the first ball screw 10 is fixedly connected with a transverse moving table 11 by screws. The transverse moving table 11 is slidably connected with the base 8. A second motor 12 is fixedly connected by bolts at the central position of the outer wall of one side of the transverse moving table 11. The second motor 12 is fixedly connected with a second ball screw 13 through the output end on its one side. The first ball screw 10 and the second ball screw 13 are perpendicular to each other. Cavities are formed at the top of the base 8 near the outer sides of the first ball screw 10 and the second ball screw 13. The nut seat on the second ball screw 13 is fixedly connected with a longitudinal moving block 14 by screws. The longitudinal moving block 14 is slidably connected with the transverse moving table 11. An electric push rod 15 is fixedly connected by bolts at the central position of the top of the longitudinal moving block 14. The electric push rod 15 is fixedly connected with a knockout head 16 through the output end on its one side. A knockout head 17 is embedded in the knockout hole 6. A sealing ring seat 18 is integrally formed at the top of the knockout head 17, and a fitting hole 19 is formed at the central position of the bottom of the knockout head 17.

[0024] It should be noted that since the existing hot top casting die for aluminum alloy rods will form multiple aluminum alloy rods in one casting, most of these aluminum alloy rods are knocked out at one time by a knockout mechanism. When taking some heavier aluminum alloy rods, lifting equipment is needed for hoisting. Since the spacing between the aluminum alloy rods after ejection is small, the aluminum alloys are easily damaged due to mutual collision during hoisting, affecting the quality of the formed aluminum alloy rods. In this embodiment, through the position adjustment of the knockout head 16 in the horizontal direction and the precise cooperation between the knockout hole 6 and the knockout head 17, the aluminum alloy rods in multiple aluminum alloy casting sleeves 4 can be knocked out one by one, so that there are no obstacles around the aluminum alloy rods knocked out, thus avoiding the problem of collision damage caused by shaking during subsequent hoisting and taking of aluminum alloy rods. Through the knockout hole 6, the knockout head 16, the knockout head 17 and the fitting hole 19 with limiting ability, the sealing performance of the knockout hole 6 before and after knockout can be ensured, and the leakage of molten aluminum alloy liquid can be avoided.

[0025] Specifically, in this embodiment, the solution mainly includes a sealing ring groove 5, a blanking hole 6, a pusher head 16, a blanking head 17, and a sealing ring seat 18. When the aluminum alloy rod is cooled and formed in the aluminum alloy casting sleeve 4 and the casting is completed, the switches of the first motor 9 and the second motor 12 are controlled by an external PLC controller (not shown in the figure). First, the first motor 9 drives the first ball screw 10 to rotate through the output end on one side thereof, and the horizontal moving table 11 on the first ball screw 10 horizontally moves on the base 8. The second motor 12 drives the second ball screw 13 to rotate through the output end on one side thereof, and the longitudinal moving block 14 on the second ball screw 13 horizontally moves longitudinally on the horizontal moving table 11, so as to realize the horizontal and longitudinal position adjustment of the electric push rod 15 in the horizontal direction. When the pusher head 16 at the output end of the electric push rod 15 is controlled to move to directly below the blanking hole 6, the electric push rod 15 drives the pusher head 16 to move upward through the output end on one side thereof. During the upward movement of the pusher head 16, it is inserted into the fitting hole 19 opened at the bottom of the blanking head 17. The blanking head 17 is precisely sleeved outside the pusher head 16. As the pusher head 16 continues to move upward, the pusher head 16 pushes the blanking head 17 out of the blanking hole 6. After the sealing ring seat 18 at the top of the blanking head 17 contacts the aluminum alloy rod inside the aluminum alloy casting sleeve 4, it pushes the aluminum alloy rod out, so that the aluminum alloy rod protrudes out of the aluminum alloy casting sleeve 4. After the aluminum alloy rod is lifted and taken out, the electric push rod 15 drives the pusher head 16 to reset through the output end on one side thereof. The pusher head 16 moves downward, and the blanking head 17 sleeved outside the pusher head 16 precisely falls into the blanking hole 6, and the sealing ring seat 18 precisely falls into the sealing ring groove 5. The pusher head 16 is used to push out the aluminum alloy rods in the lower mold 1 one by one.

[0026] In a further preferred embodiment of the present utility model, as Figures 3-5 shown, the centers of the aluminum alloy casting sleeve 4, the sealing ring groove 5, and the blanking hole 6 are on the same vertical axis. The sealing ring groove 5 and the blanking hole 6 are communicated, and the cross-section of the combination of the sealing ring groove 5 and the blanking hole 6 is a T-shaped structure.

[0027] In this embodiment, through the blanking port formed by the sealing ring groove 5 and the blanking hole 6, and by using the pusher head 16 and the blanking head 17, the aluminum alloy rod formed in the aluminum alloy casting sleeve 4 can be precisely penetrated through the sealing ring groove 5 and the blanking hole 6, so as to push out the aluminum alloy rod.

[0028] In a further preferred embodiment of the present utility model, as Figures 3-5 shown, the pusher head 16 is embedded inside the fitting hole 19, and the pusher head 16 and the fitting hole 19 are precisely matched and fitted. The blanking hole 6 and the blanking head 17 are matched and fitted, and the sealing ring groove 5 and the sealing ring seat 18 are matched and fitted.

[0029] In this embodiment, through the matching and fitting, it can be ensured that the pusher head 16 is precisely inserted into the fitting hole 19, and the blanking head 17 can precisely seal the blanking hole 6.
