Problems solved by technology

[0005] 1. In order to shorten the pouring time and ensure the temperature of the molten iron, the volume of the ladle needs to be made very large, and the speed of molten metal flowing out of the ladle should be increased as much as possible. However, in this way, it is difficult to stop pouring in time when resetting, and the pouring is easy to be excessive , resulting in poor pouring effect
[0006] 2. During the tilting pouring process, the flow of molten metal tends to be turbulent, and the entrained gas flows into the mold cavity with the liquid, so that the vibration of the molten metal will affect the pouring quality
[0007] 3. The molten metal is an ordinary molten metal, which cannot meet the requirement of pouring to follow the flow of the molten metal, and the quality of the poured castings is not high
[0008] 4. When there are various types of castings, in order to improve the accuracy of measurement, it is necessary to adjust the inclination of the ladle and accurately estimate the outflow of the ladle. In this way, the flow control of the pouring process becomes very complicated, especially for 15 For pouring less than 1 kg, it is easy to pour too much or insufficient pouring, and the pouring quality is not high
[0009] 5. Since the ladle rotates along its central axis, the molten metal flowing out of the sprue has a wide range of falling points, requiring a large diameter of the pouring hole of the casting. During pouring, the molten metal is likely to vibrate in the pouring hole of the casting, which affects the pouring quality

Embodiment 1

[0068] Example 1, such as Figure 1 to Figure 10 As shown, a high-precision automatic pouring machine includes a ladle system, a ladle lateral movement and longitudinal movement system, a servo tilting mechanism, a detection unit, and a control unit, and is characterized in that:

[0069] The ladle system includes a ladle 6 made of thermal insulation material and a ladle moving device. The ladle 6 includes a ladle body 604. The ladle body 604 is a barrel-shaped structure without a cover. One side of the ladle body 604 is provided with A through hole 601, a protruding ladle nozzle 60 is connected to the through hole 601, a pouring liquid channel 66 is provided in the ladle nozzle 60, and a partition is provided on the diameter of the position directly below the through hole 601 on the bottom surface of the ladle body 604 Plate 69, the distance of the top surface of dividing plate 69 from the bottom surface of ladle body 604 is less than the distance of through hole 601 from the...

Embodiment 2

[0105] Example 2. Such as Figure 11 , Figure 12 As shown, the only difference between this embodiment and Embodiment 1 is: the diameter of the top end of the ladle body 604 is greater than the diameter of the bottom end; There is an inclined surface 607 between them, and the bottom surface of the ladle nozzle 60 is in the same plane as the inclined surface; the angle between the inclined surface 607 and the bottom surface of the ladle body 604 is 35-45 degrees. The included angle between the slope 607 and the bottom surface of the ladle body 604 is 35-45 degrees, which ensures that the ladle mouth has a good slag blocking effect.

[0106] An electric heating tube is arranged on the cover to heat the molten metal. Usually, the side wall and bottom of the ladle itself are made of refractory and heat-insulating materials. Due to continuous operation, the temperature drop is not obvious and does not affect the pouring temperature. However, when the pouring temperature has sp...

Abstract

The invention discloses a high-precision full-automatic casting machine. The high-precision full-automatic casting machine comprises a casting ladle system, a casting ladle transverse moving and longitudinal moving system, a servo tilt-rotating mechanism, a detection unit and a control unit. The casting ladle system comprises a casting ladle made of thermal insulation materials and a casting ladle moving device. The casting ladle transverse moving and longitudinal moving system comprises a track system and a casting vehicle. The detection unit comprises a load sensor. The load sensor is used for detecting the weight of molten metal in the casting ladle of the casting machine and generating a signal representing the detected weight. The control unit is provided with a first arithmetic unit, a second arithmetic unit and a driving indication unit. The casting machine can effectively shorten the casting time and improve the casting stability.

Description

technical field [0001] The invention relates to an automatic pouring device, in particular to a high-precision full-automatic pouring machine capable of pouring molten metal into a mold. Background technique [0002] As we all know, in the casting process production process, the following process is usually carried out: making the same number of casting molds as required by the casting and having a cavity with a shape corresponding to the target casting; on the other hand, using a conveyor line The casting molds of this shape are conveyed sequentially, and during the conveying process, molten liquid is poured into the cavities of the respective casting molds, and then the castings cooled and solidified in the cavities of the respective casting molds are taken out from the respective casting molds at the end of the conveying line. [0003] In addition, it has been desired to save labor and improve the efficiency of the above-mentioned series of casting processes. In particula...
