Description

Technical Field

[0001] The utility model relates to the field of casting equipment, in particular to an improved casting pouring device. Background Art

[0002] The primary function of a casting pouring apparatus is to receive molten metal and direct it into the mold cavity within the sand mold box for pouring. The quality of a casting is closely linked to the structure of the pouring apparatus. Current improvements to the pouring apparatus's runners, utilizing various runner configurations to control the flow direction and distribution of the molten metal, ensure smooth filling of the mold cavity and avoid numerous casting defects. However, the temperature of the molten metal contained in the pouring cup fluctuates during the pouring process, causing variations in the flow rate. Failure to adjust the pouring flow rate to match the temperature can also affect casting quality. Furthermore, inaccurate control of the total amount of metal temporarily deposited into the pouring cup can result in material shortages, preventing continuous pouring, or excessive stockpiles that are wasted and difficult to clean. Currently, for personalized, small-batch castings, controlling the temperature and flow rate of the metal, as well as the amount of material added each time, is largely manual. This uncertainty in manual control can lead to unstable casting quality and increased production costs due to excess metal. In view of this, it is necessary to improve the pouring device for casting. If the pouring device can have dynamic temperature measurement, flow control and metering functions, it will improve the quality of castings and reduce production costs. This is the problem to be solved in this case. Utility Model Content

The upper portion of the screw shaft 223 can pass through the shaft hole 142 on the top plate of the support frame 14 and can rotate in the shaft hole 142.

The lifting plate 221 passes through the avoidance groove 141 and is locked on the slider provided with the guide rail 15.The second load cell 224 can be one or more. The second load cell 224 is positioned between the bottom of the pouring cup 211 and the lifting plate 221 and connected to the bottom of the pouring cup 211 and the suspended end of the lifting plate 221. In this embodiment, there are three second load cells 224, arranged in an equilateral triangle. The pouring device also includes an electronic control unit, which includes a control motherboard and a display screen. The metering base assembly 1 and the pouring assembly 2 are both electrically connected to the electronic control unit. The electronic control unit can receive weight information dynamically collected by the first load cell 13 and the second load cell 224, analyze and process it, and display it on the display screen. The electronic control unit can also receive temperature information dynamically collected by the temperature sensor 214, analyze and process it, and control the opening degree of the flow control valve 213 to control the flow of liquid at the outlet of the pouring cup 211.

[0029] The method of using the improved casting pouring device described in the utility model is as follows:

[0030] Due to the limited capacity of the pouring cup 211 and the inconvenience of continuously keeping the stored liquid material warm, continuous pouring of castings, especially continuous pouring of large castings or continuous pouring of multiple castings at the same time, mostly requires multiple feedings to the pouring cup 211. Therefore, this pouring device measures the weight of multiple feedings to the pouring cup 211 by setting a weighing sensor, so that the feeding amount is more accurate and controllable.

[0031] Before using this device, the total weight parameter of the casting to be cast and the weight parameter for alarm are set in the electronic control unit. The weight parameter for alarm is the artificially set weight of the liquid material that is still missing in the sand mold box 900 before the end of pouring. When this weight parameter is reached during pouring, an alarm can be displayed on the display screen; the electronic control unit also sets the weight parameter that needs to be displayed on the display screen each time the liquid material in the pouring cup 211 is discharged to a certain amount; the electronic control unit also sets the temperature range of the liquid material in the pouring cup 211 in the optimal pouring state and the corresponding relationship function between the temperature change of the liquid material in the pouring cup 211 and the opening state of the flow control valve 213 when the temperature range is exceeded.

[0032] When in use, first rotate the screw shaft 223 of the lifting assembly 22 to drive the pouring cup 211 of the liquid injection assembly 21 to rise, place the sand mold box 900 to be poured with molten metal on the table 12 of the metering seat assembly 1, and then drive the pouring cup 211 down to make the lower part of the pouring cup discharge pipe 2111 completely inserted into the runner feed pipe 2121, until the pouring cup discharge pipe 2111 and the runner feed pipe 2121 are tightly fitted, then the hot melt liquid metal can be added to the pouring cup 211 for the first time and poured, and the first weighing sensor 13 and the second weighing sensor 224 are both dynamically weighed and measured; when the alarm on the display shows that the pouring cup 2 If the remaining amount of liquid material added in the first step is insufficient, a second step of adding liquid material to the pouring cup 211 is performed, and the material is added multiple times in this manner until the display screen displays an alarm indicating the weight of the liquid material still missing in the sand mold box 900 before the pouring is completed. At this time, the electronic control unit will analyze and calculate the weight of the liquid material still missing in the sand mold box 900 and the weight of the liquid material still remaining in the pouring cup 211, and calculate how much liquid material needs to be added to the pouring cup 211 to complete the casting without leaving any residual material in the pouring cup 211. Adding liquid material to the pouring cup 211 according to the calculated result can ensure continuous pouring without wasting residual material. In addition, if the temperature sensor 214 detects that the temperature of the liquid material in the pouring cup 211 exceeds the temperature range for the optimal pouring state, the electronic control unit can also instruct the flow control valve 213 to control the liquid flow rate of the pouring cup discharge pipe 2111.

[0033] The utility model improves the pouring device for casting, integrates the pouring assembly 2 provided with a liquid injection fitting 21 and a lifting fitting 22 on a metering base assembly 1 that can be weighed and measured, and uses the first weighing sensor 13 of the metering base assembly 1 to dynamically measure the weight change of the sand mold box 900 placed thereon during the pouring of molten metal, and feeds back to the pouring assembly 2 so as to accurately put the subsequent required amount of material into the pouring cup 211 of the pouring assembly 2, thereby ensuring continuous pouring without causing excessive waste of material; using the temperature sensor 214 and the flow control valve 213 provided on the liquid injection fitting 21 of the pouring assembly 2, the liquid temperature in the pouring cup 211 can be dynamically detected and the liquid flow rate at the outlet of the pouring cup 211 can be controlled, and the temperature change of the liquid can be adapted by controlling the flow change of the liquid, thereby improving the quality of castings and reducing production costs.

[0034] The above is only a specific embodiment of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
