Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical equipment parts processing technology, and specifically relates to a sand mold vibration compaction device for producing counterweights. Background Technology
[0002] A counterweight is a rigid component that balances or stabilizes equipment or structures using its own weight. It is usually made of high-density materials such as metal and concrete and is in the form of regular blocks or sheets. Its core function is to provide a controllable load to counteract motion inertia, adjust the center of gravity, or increase system stability. It is commonly used in mechanical bases, lifting equipment, fitness equipment, and other scenarios. However, traditional sand mold compaction devices use unidirectional vibration, which limits the flowability and filling capacity of sand particles in the mold. This can easily lead to insufficient compaction at the edges or complex cavities of the sand mold, resulting in local looseness or porosity defects. Furthermore, it is difficult to quickly match the different compaction requirements of different sand molds or counterweights, which may cause local over-tightness or looseness defects in the sand mold. The inability to accurately adapt to the characteristics of the sand mold also increases the scrap rate. To solve the problems mentioned above, we propose a sand mold compaction device for counterweight production. Utility Model Content
[0003] The purpose of this utility model is to provide a sand mold vibration compaction device for the production of counterweights, which has the advantages of multi-directional vibration and vibration amplitude adjustment.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sand mold vibration compaction device for producing counterweight blocks, comprising a movable box, springs A being bolted to the four corners of the bottom of the movable box, a placement plate being bolted to the top of the springs A, a connecting rod being hinged to the left side of the top of the movable box, a connecting shaft being rotatably connected to the left side of the bottom of the connecting rod, a connecting block being bolted to the bottom of the connecting shaft, and an adjustment mechanism being provided at the bottom of the connecting block.
[0005] The above technical solution involves: a motor driving an adjustment box to rotate, the adjustment box driving a connecting block to rotate, the adjustment box driving a connecting shaft to rotate, the connecting shaft driving a connecting rod to move, the connecting rod driving a moving box to move, the moving box driving spring A to move and extend / retract, and spring A driving a placement plate to move and vibrate. This multi-directional vibration sand mold compaction device significantly improves the overall compactness and uniformity of the counterweight sand mold, especially in complex cavities or corners. Through the synergistic effect of multi-directional vibration forces, the sand particles are made to fill the mold gaps more densely and orderly, reducing local looseness or porosity defects. This vibration method not only adapts to the needs of sand molds of different shapes and sizes but also effectively shortens the compaction time and reduces the frequency of manual sand replenishment and adjustment, thereby improving production efficiency while ensuring a dense internal structure after casting.
[0006] The present invention is further configured such that the adjustment mechanism includes an adjustment box, the adjustment box is located at the bottom of the connecting block, the front end of the adjustment box is provided with a slot, a buckle is engaged inside the slot on the right side, a spring B is bolted to the back of the buckle, and the back of the spring B is bolted to the front of the connecting block, and a damper is sleeved inside the spring B.
[0007] The above technical solution employs an adjustment mechanism. By holding the connecting rod and moving it to the left, the connecting shaft moves, which in turn moves the connecting block. The connecting block then moves the spring B, which in turn moves the latch. The latch moves and retracts along the path of the slot, causing the spring B to retract as well. The damper limits the spring B, which moves to the left slot. The spring B then rebounds, causing the latch to engage and secure with the slot. This simple mechanical switching allows for quick adaptation to different sand mold compaction requirements without relying on complex control systems or frequent component replacements. This significantly improves production flexibility, avoids sand mold breakage due to excessive vibration or uneven compaction caused by insufficient vibration, and reduces debugging difficulty and equipment maintenance costs.
[0008] The present invention is further configured such that a motor is fixedly sleeved on the left side of the bottom of the adjustment box.
[0009] The above technical solution involves incorporating a motor to drive the adjustment box to rotate.
[0010] The present invention is further configured such that a frame is embedded in the bottom of the motor.
[0011] The above technical solution, by setting up a frame, can stabilize the motor.
[0012] The present invention is further configured such that a base is bolted to the bottom of the frame, and a fixing box is bolted to the right side of the top of the base.
[0013] The above technical solution uses a base to stabilize the device.
[0014] The present invention is further configured such that sliders A are bolted to the front and back of the movable box, and grooves A are provided at the front and rear ends of the inner wall of the fixed box, and the interior of the grooves A is slidably connected to the surface of the sliders A.
[0015] The above technical solution is adopted: by setting slider A and slide groove A, the movement of the movable box can be limited.
[0016] The present invention is further configured such that a slider B is bolted to the back of the connecting block, and a groove B is provided at the rear end of the inner wall of the adjustment box, and the interior of the groove B is slidably connected to the surface of the slider B.
[0017] The above technical solution allows for the limiting of the movement of the connecting block by setting slider B and groove B.
[0018] The present invention is further configured such that a baffle is bolted to the top of the placement plate.
[0019] The above technical solution, by setting up a baffle, can prevent sand leakage.
[0020] In summary, this utility model has the following beneficial effects:
[0021] 1. This utility model can significantly improve the overall compactness and uniformity of the counterweight sand mold by adopting a multi-directional vibration sand mold compaction device. Especially in complex cavities or corners, the synergistic effect of multi-directional vibration forces promotes the sand particles to fill the mold gaps more tightly and orderly, reducing local looseness or porosity defects. This vibration method can not only adapt to the needs of sand molds of different shapes and sizes, but also effectively shorten the compaction time and reduce the frequency of manual sand replenishment and adjustment, thereby improving production efficiency and ensuring that the internal structure of the casting is dense after molding.
[0022] 2. This utility model can quickly adapt to different sand mold compaction requirements through simple mechanical clamping switching, without relying on complex control systems or frequent parts replacement, significantly improving production flexibility, avoiding sand mold damage caused by excessive vibration or uneven compaction caused by insufficient vibration, and reducing debugging difficulty and equipment maintenance costs.
