Description

A kind of bearing sleeve steel film embedded sand casting equipment and method

Technical field

The present invention relates to the technical field of bearing seat mold casting, and more specifically, to a bearing sleeve steel film sand-embedded casting equipment and method.

Background technique

The casting mechanism is one of the indispensable devices in the work of embedding sand into the steel film of the bearing sleeve. It can inject the melted casting liquid containing gravel into the mold, and after cooling, it becomes the steel film of the bearing sleeve. In view of this , the traditional device is not perfect, and there is no facility to facilitate the quantitative control of the casting liquid. However, a bearing sleeve steel film sand-embedded casting mechanism can provide convenience for workers.

The existing casting mechanism usually requires workers to manually pour the casting liquid into the inside of the mold. It is easy to pour too much or too little, making it inconvenient to accurately control the amount of pouring liquid and reducing product quality.

The Chinese patent with the authorized publication number CN219818011U discloses a bearing sleeve steel film embedded sand casting mechanism. By installing a storage tank, the staff first injects an appropriate amount of casting liquid into the storage tank, places the mold at the corresponding bottom of the cylinder, and then Grasp the threaded ring and rotate it so that the threaded ring rotates along the screw under the action of external force. The threaded ring moves up and down using the thread action of the screw. After moving the threaded ring to the position corresponding to the appropriate scale, open the solenoid valve 1 and close the solenoid. Valve 2 starts the cylinder at the same time to drive the telescopic rod to extend, so that the telescopic rod drives the long plate to move upward. The long plate drives the circular plate and piston to move upward through the inserted rod, so that the pressure inside the cylinder is reduced, and the pressure difference with the outside world is used. Press the casting liquid inside the storage tank into the inside of the cylinder through the connecting pipe. The amount of casting liquid entering the inside of the cylinder is the value of the scale. Then close the solenoid valve one, open the solenoid valve two, and at the same time start the cylinder to drive the telescopic rod one to shrink. The telescopic rod drives the long plate to move downward, allowing the piston to push the casting liquid inside the cylinder to the mold through the air. When the long plate moves downward to the extrusion control button, the control button controls the cylinder to close. At this time, the inside of the cylinder The casting liquid is completely squeezed out of the inside of the cylinder, which facilitates the staff to select the corresponding amount of casting liquid according to different types of molds and improves product quality;

Although this bearing sleeve steel film embedded sand casting mechanism can quantitatively process the pouring liquid and improve product quality, during actual use, the completed workpiece will stick to the lower mold. The traditional unloading method Using manual unloading, the stress points of manual unloading are relatively concentrated, which can easily cause damage to the workpiece and is time-consuming and labor-intensive.
