Description

Technical Field

[0001] The utility model relates to the technical field of casting equipment, in particular to a casting sand box casting device. Background Technique

[0002] In the field of mold production and manufacturing, manufacturers are often subject to special customized equipment designed by customers themselves. Most of these equipment are assembled by manufacturing individual small parts. The specifications of these individual small parts are different, and new quantitative values need to be set each time casting is performed, which is very troublesome. Moreover, it takes a certain amount of time from casting to demolding, resulting in a rather long time required for a complete equipment to come out as a whole.

[0003] After a large amount of retrieval, it is found that in the prior art, such as the automatic quantitative casting device for a casting sand box with the application number CN202222488856.0, by tightening the handle bolt, the fastening seat clamps and fixes the mold, which can achieve the purpose of fixing molds of different specifications, prevent the influence on the casting effect caused by the shaking of the mold during casting, ensure the casting quality, and has strong applicability and is worthy of promotion. Although this method can clamp the mold, it is rotated manually. Although this method is feasible, manual rotation not only has low efficiency but also requires a large amount of labor. Therefore, further improvement is needed.

[0004] Therefore, it is necessary to provide a casting sand box casting device to solve the above technical problems. Content of the Utility Model

[0005] The utility model provides a casting sand box casting device, which solves the problems in the background technique.

[0006] To solve the above technical problems, a casting sand box casting device provided by the utility model includes a base. A bearing frame is installed on the top surface of the base. A spring is vertically installed on the top surface of the base. The top end of the spring is installed with a mounting table. Vertical plates are symmetrically installed on the bottom surface of the mounting table. A bidirectional lead screw is movably installed between the two vertical plates. One end of the bidirectional lead screw is connected to a stepping motor. A moving plate is helically connected to the surface of the bidirectional lead screw. A threaded hole is penetrated through the surface of the moving plate. An extrusion plate is slidably arranged on the top surface of the mounting table. The bottom end of the extrusion plate is fixedly connected to the top end of the moving plate. A mold is clamped between the two extrusion plates. A pouring pipe is arranged on the top surface of the mold. A quantitative tank is penetrated through the top surface of the pouring pipe. An electromagnetic valve is installed on the surface of the pouring pipe. By setting the cooperation of the mounting table, vertical plates, bidirectional lead screw, moving plate, extrusion plate and stepping motor, it is convenient to quickly clamp and fix the mold. When operating, only need to place the mold on the top surface of the mounting table, then start the stepping motor, and then the stepping motor drives the bidirectional lead screw to rotate. Then, under the cooperation of the bidirectional lead screw and the threaded hole, the moving plate drives the extrusion plate to move, so that the two extrusion plates extrude the mold on the mounting table. This method is simple to operate and does not require manual rotation to drive the extrusion, which not only reduces the workload, but also improves the work efficiency.

The output end of the material cylinder penetrates through the surface of the bearing frame and is connected to a discharge gun. The discharge gun is located directly above the quantitative tank.

[0008] Preferably, a vibration motor is installed on the bottom surface of the mounting table, and there are two vibration motors, and the two vibration motors are symmetrically installed about the center line of the mounting table. By setting the vibrator, it is convenient to vibrate the mold after pouring to avoid the situation of air bubbles inside the mold. Moreover, the vibration motor only contacts the mounting table and does not contact the bearing frame. Therefore, during operation, only the mold is vibrated, and the bearing frame will not shake, thereby improving the stability of the bearing frame.

[0009] Preferably, a strip-shaped hole is penetrated through the top surface of the mounting table, and the internal width of the strip-shaped hole is equal to the width of the moving plate. By setting the strip-shaped hole, it is convenient to make way for the moving plate and ensure that the moving plate drives the extrusion plate to extrude the mold on the mounting table.

[0010] Preferably, there are multiple springs, and the multiple springs are equidistantly installed between the mounting table and the base. A damper is installed inside the spring. By setting multiple springs, it is convenient to support all directions of the mounting table. By setting the damper, it is convenient to play a damping role on the spring to prevent the vibration amplitude of the mounting table from being too large.

[0011] Preferably, a controller is installed on the outer surface of the carrier. By setting the controller, it is convenient to control the electrical components inside the device.

[0012] Compared with the related art, a casting sand box casting device provided by the present utility model has the following beneficial effects:
