Description

Technical Field

[0001] The invention relates to the technical field of iron mold sand coating processing, in particular to a mold base fixing component and a method for iron mold sand coating processing. Background Art

[0002] As a special casting method, iron mold sand coating technology combines the advantages of metal mold casting and sand casting. It not only ensures the precision and surface quality of the casting, but also avoids some problems that may be caused by metal mold casting through the sand coating. When flipping the lower mold, the internal workpiece and the molding sand need to be separated. At this time, it is necessary to apply vibration force to the lower mold through vibration equipment. However, when the existing processing equipment is used, due to long-term vibration and impact, the fasteners such as the fixing bolts of the conveying assembly for conveying the lower mold may loosen, resulting in the displacement of the mold position, and the guide wheel part in contact with the mold is prone to wear, affecting its fixing effect and precision. Summary of the invention

The inner ring of the turning frame is fixedly connected with an upper guide wheel abutting against the top of the lower mold side guide strip, and the inner ring of the turning frame is slidably connected with a lower guide wheel abutting against the bottom of the lower mold side guide strip driven by a hydraulic cylinder;

[0005] It also includes a floating force-bearing mechanism, which includes four fixed blocks fixedly connected to the inner ring of the flip frame and located on the upper and lower sides of the lower mold, the inner cavity of the fixed block is fixedly connected to a reset spring through an inner groove, one end of the reset spring is fixedly connected to a support rod that penetrates and extends to the outside of the fixed block, one end of the support rod away from the reset spring is fixedly connected to a receiving frame for receiving the lower mold, the surface of the support rod is rotatably connected to a force-bearing wheel, and the surface of the fixed block is provided with a guide groove for the up and down movement of the force-bearing wheel;

At this time, the upper guide wheel moves downward, and the lower guide wheel moves upward. The fixed block rotates during the rotation. At this time, the air box is inflated to make the arc-shaped support frame rise. The force-bearing wheel on the surface of the support rod abuts against the guide arc surface on the side of the arc-shaped support frame. While continuously rotating, it slowly moves upward along the guide groove, pushing the support rod and the receiving frame upward. When the flip is completed, the two receiving frames are lifted up to support the lower mold. At this time, the air box is filled with gas to support the arc-shaped support frame through the top frame. , and then the upper guide wheel is driven downward by the hydraulic cylinder to separate from the lower mold, and then the lower mold falls completely above the receiving frame. At this time, the vibration component is pressed down to contact the upper part of the lower mold, and then vibrates to separate the internal molding sand and the workpiece from the lower mold. During the vibration, the receiving frame is subjected to force, driving the arc support frame to vibrate, and the top frame squeezes the elastic sealing pad downward in the air box, exerts pressure on the movable seat and the support spring, and plays an effective supporting role on the arc support frame, which can buffer the vibration force applied by the upper vibration component and ensure the support for the lower mold.

[0010] As a further solution of the present invention: three top frames are provided and are symmetrically arranged in the inner cavity of the air box. The arc-shaped support frame is fixed at multiple points by multiple top frames, and the supporting effect is better.

[0011] As a further solution of the present invention: two supporting mechanisms are provided, and are arranged on both sides of the flip frame to support the two sides of the flipped lower mold respectively.

[0012] A method for fixing a mold base for sand-coated iron molds comprises the following steps:

[0013] Step 1: The lower mold is conveyed to the inside of the turning frame by a horizontal conveyor belt. At this time, the upper guide wheel and the lower guide wheel abut against the guide strip on the side of the lower mold, and the lower mold is clamped between the upper guide wheel and the lower guide wheel;

[0014] Step 2, the driving mechanism in the fixed seat drives the flip frame to flip 180 degrees to drive the lower mold to flip. At this time, the upper guide wheel moves to the bottom, and the lower guide wheel moves to the top. The fixed block rotates during the rotation. At this time, the air box is inflated to make the arc-shaped support frame rise, and the force-bearing wheel on the surface of the support rod abuts against the guide arc surface on the side of the arc-shaped support frame. While continuously rotating, it slowly moves upward along the guide groove, pushing the support rod and the receiving frame to move upward. When the flipping is completed, the two receiving frames are lifted up to support the lower mold. At this time, the air box is filled with gas, and the arc-shaped support frame is supported by the top frame. Then the upper guide wheel is driven downward by the hydraulic cylinder to separate from the lower mold, and then the lower mold completely falls on the top of the receiving frame;

[0015] Step 3, the vibration component is pressed down to contact the top of the lower mold, and then vibrates to separate the internal molding sand and the workpiece from the lower mold. During the vibration, the receiving frame is subjected to force, driving the arc support frame to vibrate, and the top frame squeezes the elastic sealing pad downward in the air box, exerts pressure on the movable seat and the support spring, and plays an effective supporting role on the arc support frame, which can buffer the vibration force applied by the upper vibration component and ensure the supporting effect on the lower mold. After separation, the hydraulic cylinder drives the upper guide wheel to reset, and then the gas inside the air box is extracted, and the receiving frame below is lowered and separated from the lower mold. Then, the lower mold is output by rotating the upper guide wheel and the lower guide wheel, and then the new lower mold is input to repeat the above steps, and the operation is cyclic. Through the setting of the floating force-bearing mechanism and the supporting mechanism, while the lower mold can be flipped and conveyed normally, it can support its vibration state, and it can be adaptively adjusted as it flips. When the lower mold vibrates, the flip frame can be prevented from being vibrated, thereby increasing the overall service life of the equipment.

[0018] 2. When the present invention is in use, the arc-shaped support frame is forced to press the top frame downward, and the top frame presses the elastic sealing pad downward in the air box, exerting pressure on the movable seat and the supporting spring, thereby effectively supporting the arc-shaped support frame, being able to buffer the vibration force exerted by the upper vibration component, and ensuring the supporting effect on the lower mold, thereby ensuring good supporting and stability while ensuring the sealing effect.
