Description

Technical Field

[0001] The utility model relates to the technical field of sand-covering and sand-discharging equipment for iron molds, in particular to an automatic sand-discharging device for sand-covering iron molds. Background Art

[0002] Iron mold sand-coated casting production technology is a semi-precision casting method that is different from casting methods such as sand casting, lost foam casting, and metal mold casting. This method uses a cast iron model and a cast iron cavity that is close to the shape of the casting as a sand box iron mold. The close-shaped iron mold is covered with a layer of coated sand to form a casting mold for pouring into the casting - this is iron mold sand-coated casting; Patent No. CN202123050046.9 discloses an automatic sand discharge device for iron mold sand coating. By turning two rotating handles clockwise, the rolling ball is driven to approach and contact the extrusion conveyor device. The device is fixedly installed on the conveyor device that conveys the iron mold and the shaped sand box. By opening the control valve, the coated sand in the sand discharge hopper falls into the shaped sand box under the action of gravity, completing the sand discharge operation of the iron mold; However, since the benchmark will move with the magnetic counterweight block, and the sand in the sand discharge hopper will move with the vibration of the conveying device, this can easily cause the counterweight block to sink with the vibration of the sand, which can easily affect the benchmark measurement. Therefore, we propose an automatic sand unloading device for sand-covered iron molds. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides an automatic sand unloading device for sand-covering an iron mold.

[0004] The technical solution adopted by the utility model to solve the technical problem is an automatic sand unloading device for sand-covered iron molds, comprising a frame, a top plate slidably mounted on the top of the frame, a sand hopper body assembled in the top plate, a pipe seat mounted on the top surface of the sand hopper body, a benchmark body for measuring sand content slidably mounted in the pipe seat, and an air bag ring assembled at one end of the benchmark body located in the sand hopper body;

[0005] The outer periphery of the tube seat is provided with a transverse hole, and there are two groups of transverse holes. A joint is threadedly installed in the transverse hole, and a conductive column that abuts the benchmark body is slidably installed at one end of the joint located in the transverse hole. A T-shaped conductive rod that is slidably connected to the conductive column is installed in the joint, and a spring for pushing the conductive column to slide is installed in the joint. A conductive ring that is electrically connected to the conductive column is installed on the outer periphery of the benchmark body, and a battery box that is electrically connected to the joint is installed on the top surface of the top plate, and an alarm light is installed on the top surface of the battery box.

[0006] By adopting the above technical solution, when the sand discharging equipment for covering the iron mold with sand is used, the benchmark body slidably installed in the pipe seat on the top of the top plate can drive the air bag ring to measure the sand content in the sand bucket body. The contact area between the air bag ring and the sand is larger, and it is not easy to fall, and it can stably drive the benchmark body to measure the sand content in the sand bucket body.

[0007] When the benchmark body slides and displaces in the tube seat, the conductive ring on the outer periphery of the benchmark body can abut against the conductive column in the inner periphery joint of the tube seat. At the same time, the spring in the joint facilitates pushing the conductive column, so that the conductive column and the T-shaped conductive rod slide against each other and can tightly abut against the conductive ring, so that the current can flow between the two sets of joints on the outer periphery of the tube seat, and the alarm light on the top of the battery box on the top plate is energized to operate, which is convenient for warning personnel and timely adding sand for covering the iron mold into the sand bucket body. When the conductive column and the conductive ring are separated from each other, the circuit is disconnected and the alarm light stops working.

[0008] Specifically, a threaded ring is assembled on the outer periphery of the benchmark body close to the airbag ring, and a threaded hole is provided in the pipe seat to be screwed together with the threaded ring.

[0009] By adopting the above technical solution, when adding sand to the sand bucket, the benchmark body can be moved, and the threaded ring on the outer periphery of the benchmark body can be screwed together with the threaded hole in the pipe seat, which is convenient for fixing the position of the benchmark body and conveniently and smoothly adding sand to the sand bucket.

[0010] Specifically, a cover plate for sealing is hinged in the top open end of the top plate through a torsion spring hinge, and there are two groups of cover plates.

[0011] By adopting the above technical solution, the cover plate is installed at the open end of the top of the top plate through a torsion spring hinge, which is convenient for automatic opening and closing, and facilitates stable addition of sand raw materials to the sand hopper body.

[0012] Specifically, a rubber sleeve that matches the pole body is assembled in the pipe seat.

[0013] By adopting the above technical solution, the rubber sleeve has a certain elasticity, which is convenient for reducing the situation where friction between the benchmark body and the tube seat causes scratches and damage.

[0014] Specifically, a rotating rod is assembled on the top surface of the pole body.

[0015] By adopting the above technical solution, the rotating rod makes it easier to rotate the pole body.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application adopts the design of the top plate, sand bucket, pipe seat, benchmark body and air bag ring. When the sand unloading equipment for covering the iron mold with sand is used, the benchmark body slidably installed in the pipe seat on the top of the top plate can drive the air bag ring to measure the sand content in the sand bucket. The contact area between the air bag ring and the sand is larger, and it is not easy to fall, and it can stably drive the benchmark body to measure the sand content in the sand bucket.

[0018] 2. The technical solution of the present application is designed with horizontal holes, joints, conductive columns, T-shaped conductive rods, springs, conductive rings, battery boxes and alarm lights. When the benchmark body slides and displaces in the tube seat, the conductive rings on the outer periphery of the benchmark body can abut against the conductive columns in the joints on the inner periphery of the tube seat. At the same time, the springs in the joints facilitate pushing the conductive columns, so that the conductive columns and the T-shaped conductive rods slide against each other and can tightly abut against the conductive rings, so that current can flow between the two sets of joints on the outer periphery of the tube seat, and the alarm light on the top of the battery box on the top plate is energized and operated, which is convenient for warning personnel and timely adding sand for covering the iron mold into the sand bucket body. When the conductive columns and the conductive rings are separated from each other, the circuit is disconnected and the alarm light stops operating. BRIEF DESCRIPTION OF THE DRAWINGS
