[0026] 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.

[0027] This embodiment provides a low-pressure aluminum casting machine, mainly to solve the problem in the prior art that the robotic arm mechanism 4 of the low-pressure casting machine can only receive castings but cannot perform subsequent batch conveying operations, and provides the following technical solution, which will be combined with... Figures 1-5 Please provide a detailed explanation:

[0028] A low-pressure aluminum casting machine includes a main frame 2 with a column 1, an opening and closing mechanism 3 mounted on the frame, and an electrical control system. It should be noted that in addition to the above structures, there are also a holding furnace, a cooling system, and an ejection structure. A robotic arm mechanism 4 electrically connected to the electrical control system is mounted on the column 1. This electrical control system is a common control system in existing casting machines, generally possessing expandable functionality, i.e., the ability to program and operate the robotic arm. This is existing technology and will not be elaborated upon here. The end of the robotic arm mechanism 4 is provided with a receiving tray 5 for receiving aluminum castings. Specifically, the receiving tray 5 is fixed to the end of the robotic arm of the robotic arm mechanism 4. This robotic arm mechanism 4 is also existing technology. When the receiving tray 5 is in the first position 6, it receives aluminum castings; when it is in the second position 7, the operation is paused. In other words, the existing electrical control system can control the robotic arm to move to the first position 6 and the second position 7 and achieve the pause function. This can also be achieved through programming or limit switches, but since it is existing technology, it will not be described in detail here.

[0029] The main improvement of this application is that a receiving box 8 is provided on the ground between the first position 6 and the second position 7. A lever 9 is fixedly installed on the receiving box 8. The lever 9 is L-shaped and fixed to the top side of the box body 81, so that when the receiving tray 5 moves from the first position 6 to the second position 7, the lever 9 will push the aluminum casting on it into the box body 81. Please refer to [link / reference]. Figures 1 to 3When the robotic arm moves the receiving tray 5, which holds aluminum castings, from the first position 6 to the second position 7, the aluminum castings can be knocked over by the lever 9 and fall into the receiving box 8, thereby realizing the automatic unloading function combined with the existing technology. In order to enable batch export, a conveyor belt 10 is also included. Therefore, this application uses the receiving box 8 and the lever 9 installed on the receiving box 8 to automatically unload the aluminum castings into the receiving box 8, thereby realizing the function of batch unloading of aluminum castings combined with the existing technology.

[0030] like Figure 4 and Figure 5 As shown, in this embodiment, in order to transfer the aluminum casting from the receiving box 8 to the conveyor belt 10, the receiving box 8 includes a box body 81 and a lifting mechanism 82 installed in the box body 81. The lifting mechanism 82 is used to transfer the aluminum casting to the conveyor belt 10. Specifically, a receiving bucket 11 is provided in the box body 81 and the receiving bucket 11 can move up and down along the height of the box body 81. The inner bottom of the receiving bucket 11 is inclined so that the aluminum casting on it can slide down along the inclined surface. When the baffle pushes the aluminum casting into the receiving box 8, it first falls into the receiving bucket 11. Specifically, the function of the receiving bucket 11 moving up and down is achieved by the sliding groove 12 opened on the side wall of one opposite side of the box body 81, and the side wall of the receiving bucket 11 is constructed with a first slider 13 that slides in the sliding groove 12. The height moves up and down by the sliding of the first slider 13 on the side wall of the receiving bucket 11 in the sliding groove 12.

[0031] like Figure 4 and Figure 5 As shown in this embodiment, the specific structure of the lifting mechanism 82 is described in detail. The lifting mechanism 82 includes a support plate 821 slidably placed inside the housing 81. The side wall of the support plate 821 is constructed with a second slider 822 slidably placed inside the slide groove 12. A pressure sensor 823 is fixed to the bottom of one of the second sliders 822. An electric push rod 824 is fixed to the side wall of the housing 81. The end of the output shaft of the electric push rod 824 is fixed to the mounting location of the pressure sensor 823. When the aluminum casting falls into the receiving hopper 11, it will cause a pressure change in the pressure sensor 823. It should be noted that the pressure sensor 823 and the electric push rod 824 are... All push rods 824 are electrically connected to the electrical control system. That is, the electrical control system controls the pressure sensor 823 and the electric push rod 824. When the pressure sensor 823 detects a change in pressure, it transmits an electrical signal to the electrical control system, which then controls the electric push rod 824 to shorten. The side wall of the housing 81 is provided with an opening 16 for the aluminum casting to slide down. The conveyor belt 10 is inclined and its upper end is located at the opening 16. When the electric push rod 824 shortens, the aluminum casting will follow and fall down, then slide down the inclined surface of the receiving bucket 11 and fall onto the conveyor belt 10 through the opening 16, where it will be conveyed out.

[0032] like Figure 4 and Figure 5As shown, in this embodiment, in order to avoid excessive impact caused by the aluminum casting falling into the receiving bucket 11, a plurality of guide posts 14 that slide through the support plate 821 are fixed at the bottom of the receiving bucket 11. A spring 15 is fixed between the bottom of the receiving bucket 11 and the support plate 821. The guide posts 14 guide the receiving bucket 11 to slide up and down under the guidance of the support plate 821, and are buffered by the spring 15. At the same time, a shock absorber is provided between the support plate 821 and the receiving bucket 11 to absorb kinetic energy.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
