[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: Figure 1 - Figure 5 As shown, the utility model provides a quantitative pouring device for casting processing, comprising a fixed plate 1, a quantitative pouring mechanism 2 is provided at the lower end of the fixed plate 1, a height adjustment mechanism 3 is provided at the lower end of the fixed plate 1, and a pressurizing mechanism 4 is provided at the upper end of the fixed plate 1;

[0026] The quantitative pouring mechanism 2 includes a quantitative barrel 21 and a control system 22. A flow sensor 23 is fixedly installed at the lower end of the quantitative barrel 21, and a pouring head 24 is fixedly installed at the lower end of the flow sensor 23. A pressure sensor 25 is fixedly installed at the lower end of the quantitative barrel 21, and one end of the pressure sensor 25 penetrates into the interior of the quantitative barrel 21. A pressure plate 26 is provided inside the quantitative barrel 21, and a liquid level sensor 27 is installed through the upper end of the pressure plate 26. The outer wall of the pressure plate 26 contacts the inner wall of the quantitative barrel 21. The flow sensor 23, the pressure sensor 25 and the liquid level sensor 27 are all connected to the control system 22 for signal communication.

[0027] The pressurizing mechanism 4 includes a support frame plate 41 and a triangular support plate 42. A cylinder 43 is fixedly mounted on one side of the triangular support plate 42. A pressurizing rod 44 is fixedly mounted on the extended end of the cylinder 43. The lower end of the pressurizing rod 44 passes through the upper end of the support frame plate 41 and is fixed to the upper end of the pressurizing plate 26. The cylinder 43 is connected to the control system 22 for signal communication.

[0028] The outer wall of the metering barrel 21 is fixed to the inner wall of the fixed plate 1, one end of the control system 22 is fixed to the fixed plate 1 and one end of the support frame plate 41, the lower end of the triangular support plate 42 is fixed to the upper end of the support frame plate 41, and the four protrusions at the lower end of the support frame plate 41 are all fixed to the upper end of the fixed plate 1.

[0029] The following describes in detail the specific configuration and function of this embodiment. By operating the control system 22 in advance and inputting the desired pouring value into the control system 22, the flow sensor 23, the pressure sensor 25, the liquid level sensor 27, and the cylinder 43 are connected to the control system 22 by signal. The control system 22 can receive signals from the flow sensor 23, the pressure sensor 25, and the liquid level sensor 27 in real time, and perform data processing and analysis. By analyzing the received data, the cylinder 43 is controlled to operate, so that the extended end of the cylinder 43 pushes the pressure rod 44 to move inside the metering barrel 21, and the pressure rod 44 pushes the pressure plate 26 to move inside the metering barrel 21, and pushes the metal liquid inside the metering barrel 21 downward. The metal liquid can then be guided out of the metering barrel 21 and introduced into the pouring head 24 through the flow sensor 23, and then flows out from the pouring head 24. This allows the pouring amount to be controlled and the accuracy of the pouring amount to be ensured, which not only saves time and resources but also reduces the cost of raw materials.

[0030] The provision of the triangular support plate 42 can provide support for the cylinder 43 and facilitate the installation of the cylinder 43 on the side wall of the triangular support plate 42;

[0031] Flow sensor 23, used to measure the flow rate of molten metal;

[0032] Pressure sensor 25, detects pressure changes during the pouring process to assist in controlling the pouring amount;

[0033] Liquid level sensor 27, monitors the liquid level in the molten metal container and provides a basis for quantitative control;

[0034] The control system 22 receives signals from the flow sensor 23, the pressure sensor 25 and the liquid level sensor 27, processes and analyzes the data, and issues control instructions to adjust the pouring speed and flow rate.

[0035] Example 2: Figure 1 and Figure 5As shown, the height adjustment mechanism 3 includes a base 31, and two groups of telescopic rods 32 are fixedly installed on the upper end of the base 31. The protruding ends of the two groups of telescopic rods 32 are fixed to the lower end of the fixed plate 1. Guide cylinders 33 are fixedly installed on the upper end of the base 31 and at the four corners. Guide rods 34 are slidably installed inside the four groups of guide cylinders 33, and the upper ends of the four groups of guide rods 34 are fixed to the lower end of the fixed plate 1.

[0036] The effect achieved by the entire embodiment is that by synchronously activating the two sets of telescopic rods 32, the extended ends of the two sets of telescopic rods 32 drive the fixed plate 1 to move up and down, and the fixed plate 1 drives the metering barrel 21 and the support frame plate 41 to move up and down together. At the same time, the metering barrel 21 drives the pouring head 24 to move up and down through the flow sensor 23, thereby adjusting the height of the pouring head 24, thereby facilitating the pouring head 24 to approach the port of the casting mold, so that the pouring head 24 can subsequently pour into the casting mold;

[0037] When the fixed plate 1 moves up and down, the fixed plate 1 will drive the four groups of guide rods 34 to move up and down together. The four groups of guide rods 34 slide up and down inside the four groups of guide cylinders 33 respectively, which can guide and assist the four groups of guide rods 34, thereby increasing the stability of the fixed plate 1 when moving up and down.

[0038] The method of use and working principle of this device are as follows: First, add metal liquid into the dosing barrel 21, then operate the control system 22 in advance and input the value to be poured into the control system 22. Then, start the two sets of telescopic rods 32 synchronously. The extended ends of the two sets of telescopic rods 32 drive the fixed plate 1 to move downward, and the fixed plate 1 drives the dosing barrel 21 and the support frame plate 41 to move downward together. At the same time, the dosing barrel 21 drives the pouring head 24 to move downward through the flow sensor 23, and the pouring head 24 is inserted into the port of the casting mold. Finally, by starting the cylinder 43, the extended end of the cylinder 43 passes through the pressure rod 44. The pressure plate 26 is pushed to move, so that the pressure plate 26 moves downward inside the quantitative barrel 21 and pushes the metal liquid inside to flow downward. During the flow of the metal liquid, the flow sensor 23, the pressure sensor 25 and the liquid level sensor 27 will monitor the flow quantity in real time and transmit it to the control system 22 in real time. The control system 22 will process and analyze the received signals. When the preset value is added, the control system 22 will control the cylinder 43 to stop running to prevent the pressure plate 26 from continuing to move downward in the quantitative barrel 21, so as to control the pouring amount and ensure the accuracy of the pouring amount.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
